text: In December 2017 the company, which was named Amazon Prime Air, announced its rebranding as Amazon Air to avoid confusion with the Amazon Prime Air drone delivery service, although it continues to operate under the callsign "Prime Air".


title: Amazon Air

text: As of June 2018, Amazon Air had 20 of its 33 cargo planes based at the Cincinnati/Northern Kentucky International Airport (KCVG), with the rest flying point-to-point transit routes across the United States. Amazon Air was to move into office space at the former Comair headquarters by March 2018.

text: Amazon has completed a new regional air hub at Fort Worth Alliance Airport (KAFW) and does not airlift third-party packages. The new regional hub began operating on October 2, 2019.


title: Amazon Air

text: For 2019 and 2020, Amazon has committed to leasing 10 additional 767-300 aircraft from Air Transport Services Group, which would bring active aircraft to a total of 50. Phase one of the CVG sort facility, encompassing is scheduled for completion in 2020, while the remaining will be developed by 2025–2027 during phase two. Amazon eventually plans to have over 100 aircraft based at CVG with over 200 daily flights and 15,000 employees.

text: In July 2020, Amazon Air had secured up to six million gallons of sustainable aviation fuel (SAF) supplied by Shell Aviation and produced by World Energy.


title: Amazon Air

text: In September 2020, Amazon committed to buy four aircraft under their own operations. These are the first aircraft the company will own rather than lease. The four 767-300 aircraft were previously under the ownership of WestJet, who purchased them from Qantas in 2015. In January 2021, with passenger air traffic severely depressed and cargo traffic higher due to the COVID-19 pandemic, Amazon announced it had completed the purchase of 11 Boeing 767-300s from Delta Air Lines and WestJet.


title: Amazon Air

text: In March 2021, Amazon exercised its warrants to acquire a minority stake in Air Transport Services Group, the parent company of Amazon Air sub-lessor Air Transport International. The deal was valued at $131 million for 13.5 million shares in the company. Amazon also holds warrants to acquire a minority stake in Atlas Air Worldwide Holdings, the parent company of Atlas Air.


title: Amazon Air

text: The primary function of Amazon Air is to transport Amazon packages from distant fulfillment centers that are outside of Amazon's local ground linehaul network for a specific area. Once the buyer's order is flown from the distant fulfillment center to the buyer's region, it is either transported to the regional Amazon Sortation Center for last mile delivery either by Amazon Logistics or the United States Postal Service, or directly to the local Amazon Delivery Station for last mile delivery by Amazon Logistics.

text: Amazon Air uses ATR 72, Boeing 737 and Boeing 767 aircraft, all of which are operated by contracted partners including Atlas Air, Air Transport Services Group and ASL Aviation.


title: Recorded history

text: Recorded history or written history describes the historical events that have been recorded in a written form or other documented communication which are subsequently evaluated by historians using the historical method. For broader world history, recorded history begins with the accounts of the ancient world around the 4th millennium BC, and it coincides with the invention of writing. For some geographic regions or cultures, written history is limited to a relatively recent period in human history because of the limited use of written records. Moreover, human cultures do not always record all of the information which is considered relevant by later historians, such as the full impact of natural disasters or the names of individuals. Recorded history for particular types of information is therefore limited based on the types of records kept. Because of this, recorded history in different contexts may refer to different periods of time depending on the topic.


title: Recorded history

text: The interpretation of recorded history often relies on historical method, or the set of techniques and guidelines by which historians use primary sources and other evidence to research and then to write accounts of the past. The question of the nature, and even the possibility of an effective method for interpreting recorded history, is raised in the philosophy of history as a question of epistemology. The study of different historical methods is known as historiography, which focuses on examining how different interpreters of recorded history create different interpretations of historical evidence.


title: Recorded history

text: Prehistory traditionally refers to the span of time before recorded history, ending with the invention of writing systems. Prehistory refers to the past in an area where no written records exist, or where the writing of a culture is not understood.


title: Recorded history

text: Protohistory refers to the transition period between prehistory and history, after the advent of literacy in a society but before the writings of the first historians. Protohistory may also refer to the period during which a culture or civilization has not yet developed writing, but other cultures have noted its existence in their own writings.


title: Recorded history

text: More complete writing systems were preceded by proto-writing. Early examples are the Jiahu symbols (c. 6600 BCE), Vinča signs (c. 5300 BCE), early Indus script (c. 3500 BCE) and Nsibidi script (c. before 500 CE). There is disagreement concerning exactly when prehistory becomes history, and when proto-writing became "true writing". However, invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age in the late Neolithic of the late 4th millennium BCE. The Sumerian archaic cuneiform script and the Egyptian hieroglyphs are generally considered the earliest writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400 to 3200 BCE with earliest coherent texts from about 2600 BCE.


title: Recorded history

text: The earliest chronologies date back to the earliest civilizations of Early Dynastic Period of Egypt, Mesopotamia and the Sumerians, which emerged independently of each other from roughly 3500 BCE. Earliest recorded history, which varies greatly in quality and reliability, deals with Pharaohs and their reigns, as preserved by ancient Egyptians. Much of the earliest recorded history was re-discovered relatively recently due to archaeological dig sites findings. A number of different traditions have developed in different parts of the world as to how to interpret these ancient accounts.


title: Recorded history

text: Dionysius of Halicarnassus knew of seven predecessors of Herodotus, including Hellanicus of Lesbos, Xanthus of Lydia and Hecataeus of Miletus. He described their works as simple, unadorned accounts of their own and other cities and people, Greek or foreign, including popular legends.


title: Recorded history

text: Herodotus (484 BCE – 425 BCE) has generally been acclaimed as the "father of history" composing his "The Histories" from the 450s to the 420s BCE. However, his contemporary Thucydides (c. 460 BCE – c. 400 BCE) is credited with having first approached history with a well-developed historical method in his work the "History of the Peloponnesian War". Thucydides, unlike Herodotus, regarded history as being the product of the choices and actions of human beings, and looked at cause and effect, rather than as the result of divine intervention. History developed as a popular form of literature in later Greek and Roman societies in the works of Polybius, Tacitus and others.


title: Recorded history

text: Saint Augustine was influential in Christian and Western thought at the beginning of the medieval period. Through the Medieval and Renaissance periods, history was often studied through a sacred or religious perspective. Around 1800, German philosopher and historian Georg Wilhelm Friedrich Hegel brought philosophy and a more secular approach into historical study.


title: Recorded history

text: The "Zuo zhuan", attributed to Zuo Qiuming in the 5th century BCE covers the period from 722 to 468 BCE in a narrative form. The Book of Documents is one of the Five Classics of Chinese classic texts and one of the earliest narratives of China. The "Spring and Autumn Annals", the official chronicle of the State of Lu covering the period from 722 to 481 BCE, is arranged on annalistic principles. It is traditionally attributed to Confucius (551–479 BCE). "Zhan Guo Ce" was a renowned ancient Chinese historical compilation of sporadic materials on the Warring States period compiled between the 3rd and 1st centuries BCE.


title: Recorded history

text: Sima Qian (around 100 BCE) was the first in China to lay the groundwork for professional historical writing. His written work was the "Records of the Grand Historian", a monumental lifelong achievement in literature. Its scope extends as far back as the 16th century BCE, and it includes many treatises on specific subjects and individual biographies of prominent people, and also explores the lives and deeds of commoners, both contemporary and those of previous eras. His work influenced every subsequent author of history in China, including the prestigious Ban family of the Eastern Han dynasty era.


title: Recorded history

text: In Sri Lanka, the oldest historical text is the Mahavamsa ( 5th century CE). Buddhist monks of the Anuradhapura Maha Viharaya maintained chronicles of Sri Lankan history starting from the 3rd century BCE. These annals were combined and compiled into a single document in the 5th century by the Mahanama of Anuradhapura while Dhatusena of Anuradhapura was ruling the Anuradhapura Kingdom. It was written based on prior ancient compilations known as the "Atthakatha", which were commentaries written in Sinhala. An earlier document known as the "Dipavamsa" (4th century CE) "Island Chronicles" is much simpler and contains less information than the "Mahavamsa" and was probably compiled using the "Atthakatha" on the "Mahavamsa" as well.


title: Recorded history

text: A companion volume, the "Culavamsa" "Lesser Chronicle", compiled by Sinhala monks, covers the period from the 4th century to the British takeover of Sri Lanka in 1815. The "Culavamsa" was compiled by a number of authors of different time periods.


title: Recorded history

text: The combined work, sometimes referred to collectively as the "Mahavamsa", provides a continuous historical record of over two millennia, and is considered one of the world's longest unbroken historical accounts. It is one of the few documents containing material relating to the Nāga and Yakkha peoples, indigenous inhabitants of Lanka prior to the legendary arrival of Prince Vijaya from Singha Pura of Kalinga.


title: Recorded history

text: The Sangam literature offers a window into some aspects of the ancient South Indian culture, secular and religious beliefs, and the people. For example, in the Sangam era "Ainkurunuru" poem 202 is one of the earliest mentions of "pigtail of Brahmin boys". These poems also allude to historical incidents, ancient Tamil kings, the effect of war on loved ones and households. The "Pattinappalai" poem in the Ten Idylls group, for example, paints a description of the Chola capital, the king Karikala, the life in a harbor city with ships and merchandise for seafaring trade, the dance troupes, the bards and artists, the worship of the Hindu god Murugan and the monasteries of Buddhism and Jainism.


title: Recorded history

text: Indica is an account of Mauryan India by the Greek writer Megasthenes. The original book is now lost, but its fragments have survived in later Greek and Latin works. The earliest of these works are those by Diodorus Siculus, Strabo ("Geographica"), Pliny, and Arrian ("Indica").


title: Recorded history

text: In the preface to his book, the "Muqaddimah" (1377), the Arab historian and early sociologist, Ibn Khaldun, warned of seven mistakes that he thought that historians regularly committed. In this criticism, he approached the past as strange and in need of interpretation. Ibn Khaldun often criticized "idle superstition and uncritical acceptance of historical data." As a result, he introduced a scientific method to the study of history, and he often referred to it as his "new science". His historical method also laid the groundwork for the observation of the role of state, communication, propaganda and systematic bias in history, and he is thus considered to be the "father of historiography" or the "father of the philosophy of history".


title: Recorded history

text: While recorded history begins with the invention of writing, over time new ways of recording history have come along with the advancement of technology. History can now be recorded through photography, audio recordings, and video recordings. More recently, Internet archives have been saving copies of webpages, documenting the history of the Internet. Other methods of collecting historical information have also accompanied the change in technologies; for example, since at least the 20th century, attempts have been made to preserve oral history by recording it. Until the 2000s this was done using analogue recording methods such as cassettes and reel-to-reel tapes. With the onset of new technologies, there are now digital recordings, which may be recorded to compact disks. Nevertheless, historical record and interpretation often relies heavily on written records, partially because it dominates the extant historical materials, and partially because historians are used to communicating and researching in that medium.


title: Recorded history

text: The historical method comprises the techniques and guidelines by which historians use primary sources and other evidence to research and then to write history. Primary sources are first-hand evidence of history (usually written, but sometimes captured in other mediums) made at the time of an event by a present person. Historians think of those sources as the closest to the origin of the information or idea under study. These types of sources can provide researchers with, as Dalton and Charnigo put it, "direct, unmediated information about the object of study."


title: Recorded history

text: Historians use other types of sources to understand history as well. Secondary sources are written accounts of history based upon the evidence from primary sources. These are sources which, usually, are accounts, works, or research that analyse, assimilate, evaluate, interpret, and/or synthesize primary sources. Tertiary sources are compilations based upon primary and secondary sources and often tell a more generalized account built on the more specific research found in the first two types of sources.


title: Zipper

text: A zipper, zip, fly, or zip fastener, formerly known as a clasp locker, is a commonly used device for binding together two edges of fabric or other flexible material. Used in clothing (e.g. jackets and jeans), luggage and other bags, camping gear (e.g. tents and sleeping bags), and many other items, zippers come in a wide range of sizes, shapes, and colors. Whitcomb L. Judson, an American inventor from Chicago, in 1892 patented the original design from which the modern device evolved.


title: Zipper

text: A zipper consists of a slider mounted on two rows of metal or plastic teeth that are designed to interlock and thereby join the material to which the rows are attached. The slider, usually operated by hand, contains a Y-shaped channel that, by moving along the rows of teeth, meshes or separates them, depending on the direction of the slider's movement. The teeth may be individually discrete or shaped from a continuous coil, and are also referred to as "elements". The word "zipper" is onomatopoetic, because it was named for the sound the device makes when used, a high-pitched "zip."


title: Zipper

text: In many jackets and similar garments, the opening is closed completely when the slider is at the top end.


title: Zipper

text: Some jackets have double-separating zippers with two sliders on the tape. When the sliders are on opposite ends of the tape, the jacket is closed. If the lower slider is raised then the bottom part of the jacket may be opened to allow more comfortable sitting or bicycling. When both sliders are lowered then the zipper may be totally separated.


title: Zipper

text: Bags, suitcases and other pieces of luggage also often feature two sliders on the tape: the part of the zipper between them is unfastened. When the two sliders are located next to each other, which can be at any point along the tape, the zipper is fully closed.


title: Zipper

text: These variations are achieved by sewing one end of the zipper together, sewing both ends together, or allowing both ends of the zipper to fall completely apart.


title: Zipper

text: A zipper costs relatively little, but if it fails, the garment may be unusable until the zipper is repaired or replaced—which can be quite difficult and expensive. Problems often lie with the zipper slider; when it becomes worn it does not properly align and join the alternating teeth. With separating zippers, the insertion pin may tear loose from the tape; the tape may even disintegrate from use. If a zipper fails, it can either jam (i.e. get stuck) or partially break off.


title: Zipper

text: In 1851, Elias Howe received a patent for an "Improvement in Fastenings for Garments". He did not try seriously to market it, thus missing the recognition that he might otherwise have received. Howe's device was more like an elaborate drawstring than a true slide fastener.


title: Zipper

text: Forty-two years later, in 1893, Cleb Cleberson, who invented a pneumatic street railway, patented a "Shoe-Fastening". The device served as a (more complicated) hook-and-eye shoe fastener. With the support of businessman Colonel Lewis Walker, Judson launched the Universal Fastener Company to manufacture the new device. Judson's "clasp locker" had its public debut at the 1893 Chicago World's Fair and met with little commercial success. Judson is sometimes given credit as the inventor of the zipper, but his device was not used in clothing.


title: Zipper

text: The Universal Fastener Company moved to Hoboken, New Jersey, in 1901, reorganized as the Fastener Manufacturing and Machine Company. Gideon Sundback, a Swedish-American electrical engineer, was hired to work for the company in 1906. Good technical skills and marriage to the plant manager's daughter Elvira Aronson led Sundback to the position of head designer. The company moved to Meadville, Pennsylvania, where it operated for most of the 20th century under the name Talon, Inc. Sundback worked on improving the fastener and in 1909 he registered a patent in Germany. The US rights to this invention were on the name of the Meadville company (operating as the Hookless Fastener Co.), but Sundback retained non-U.S. rights and used these to set up in subsequent years Lightning Fastener Co. in St. Catharines, Ontario. Sundback's work with this firm has led to the common misperception that he was Canadian and that the zipper originated in that country.


title: Zipper

text: In 1916 newspapers in Australia reported displays of the "new hookless fastener", a device from America that "the world has been waiting for" by a live model in the store window of Raynor's, of Melbourne.


title: Zipper

text: Gideon Sundback increased the number of fastening elements from four per inch (about one every 6.4  mm) to ten or eleven (around every 2.5  mm), introduced two facing rows of teeth that pulled into a single piece by the slider and increased the opening for the teeth guided by the slider. The patent for the "Separable Fastener" was issued in 1917. Gideon Sundback also created the manufacturing machine for the new device. The "S-L" or "strapless" machine took a special Y-shaped wire and cut scoops from it, then punched the scoop dimple and nib, and clamped each scoop on a cloth tape to produce a continuous zipper chain. Within the first year of operation, Sundback's machinery was producing a few hundred feet (around 100 meters) of fastener per day. In March of the same year, Mathieu Burri, a Swiss inventor, improved the design by adding a lock-in system attached to the last teeth, but his version never got into production due to conflicting patents.


title: Zipper

text: In 1923 during a trip to Europe Sundback sold his European rights to Martin Othmar Winterhalter who improved the design by using ribs and grooves instead of Sundback's joints and jaws and started producing with his company Riri on a large scale first in Germany, then in Switzerland.


title: Zipper

text: The popular North American term "zipper", (UK "zip", or occasionally "zip-fastener"), came from the B. F. Goodrich Company in 1923. The company opted to use Gideon Sundback's fastener on a new type of rubber boots (or galoshes) and referred to it as the zipper, and the name stuck. The two chief uses of the zipper in its early years were for closing boots and tobacco pouches. Zippers began being used for clothing in 1925 by Schott NYC on leather jackets.


title: Zipper

text: In the 1930s, a sales campaign began for children's clothing featuring zippers. The campaign praised zippers for promoting self-reliance in young children by making it possible for them to dress themselves. The zipper beat the button in 1937 in the "Battle of the Fly", after French fashion designers raved over zippers in men's trousers. "Esquire" declared the zipper the "Newest Tailoring Idea for Men" and among the zippered fly's many virtues was that it would exclude "The Possibility of Unintentional and Embarrassing Disarray."


title: Zipper

text: The most recent innovation in the zipper's design was the introduction of models that could open on both ends, as on jackets. Today the zipper is by far the most widespread fastener, and is used on clothing, luggage, leather goods, and various other objects.


title: Zipper

text: Airtight zippers were first developed by NASA for making high-altitude pressure suits and later space suits, capable of retaining air pressure inside the suit in the vacuum of space.


title: Zipper

text: The airtight zipper is built like a standard toothed zipper, but with a waterproof sheeting (which is made of fabric-reinforced polyethylene and is bonded to the rest of the suit) wrapped around the outside of each row of zipper teeth. When the zipper is closed, the two facing sides of the plastic sheeting are squeezed tightly against one another (between the C-shaped clips) both above and below the zipper teeth, forming a double seal.


title: Zipper

text: This double-mated surface is good at retaining both vacuum and pressure, but the fit must be very tight, to press the surfaces together firmly. Consequently, these zippers are typically very stiff when zipped shut and have minimal flex or stretch. They are hard to open and close because the zipper anvil must bend apart teeth that are being held under tension. They can also be derailed (and damage the sealing surfaces) if the teeth are misaligned while straining to pull the zipper shut.


title: Zipper

text: These zippers are very common where airtight or watertight seals are needed, such as on scuba diving dry suits, ocean survival suits, and hazmat suits.


title: Zipper

text: A less common water-resistant zipper is similar in construction to a standard toothed zipper, but includes a molded plastic ridge seal similar to the mating surfaces on a Ziploc bag. Such a zipper is easier to open and close than a clipped version, and the slider has a gap above the zipper teeth for separating the ridge seal. This seal is structurally weak against internal pressure, and can be separated by pressure within the sealed container pushing outward on the ridges, which simply flex and spread apart, potentially allowing air or liquid entry through the spread-open ridges. Ridge-sealed zippers are sometimes used on lower-cost surface dry suits.


title: Zipper

text: Some zippers include a designed ability for the slider to hold in a steady open or closed position, resisting forces that would try to move the slider and open the zipper unexpectedly. There are two common ways this is accomplished:


title: Zipper

text: The zipper handle can have a short protruding pin stamped into it, which inserts between the zipper teeth through a hole on the slider, when the handle is folded down flat against the zipper teeth. This appears on some brands of trousers. The handle of the fly zipper is folded flat against the teeth when it is not in use, and the handle is held down by both slider hinge tension and the fabric flap over the fly.


title: Zipper

text: The slider can also have a two-piece hinge assembly attaching the handle to the slider, with the base of the hinge under spring tension and with protruding pins on the bottom that insert between the zipper teeth. To move the zipper, the handle is pulled outward against spring tension, lifting the pins out from between the teeth as the slider moves. When the handle is released the pins automatically engage between the zipper teeth again. They are called "auto-lock sliders".


title: Zipper

text: A three-piece version of the above uses a tiny pivoting arm held under tension inside the hinge. Pulling on the handle from any direction lifts the pivoting arm's pins out of the zipper teeth so that the slider can move.


title: Zipper

text: Forbes reported in 2003 that although the zipper market in the 1960s was dominated by Talon Zipper (USA) and Optilon (Germany), Japanese manufacturer YKK grew to become the industry giant by the 1980s. YKK held 45 percent of world market share, followed by Optilon (8 percent) and Talon Zipper (7 percent).


title: Zipper

text: In Europe, Cremalleras Rubi company established in 1926 in Spain, continues to compete with the big multinationals selling over 30 million zippers in 2012.


title: Zipper

text: In 2005, "The Guardian" reported that China had 80 percent of the international market. Most of its product is made in Qiaotou, Yongjia County.


title: Zipper

text: The zipper is analogous in function to a drawstring, but different in mechanism. A draw string works by tension in the string drawing together the eyelets of the piece together because the tension acts to straighten the string and so forces the eyelets toward a line. The zipper works by an elastic, that is, reversible, deformation of the "locking members" (teeth). The zipper teeth are shaped and sized so that the forces which act on the zipper when the garment it is sewn on is worn cannot unlock the teeth. The slider constrains the teeth positions, moves them along a given path, and acts on the teeth one-by-one in its "Y-shaped channel" and so can reversibly lock and unlock them. This is a lock and key design. In Sundback's invention the teeth are symmetric with "exterior and interior rounded surfaces" that are "elongated transversely". The teeth have a material part ("external projection") and a space ("internal recess"). The material part of one tooth is slightly smaller than the space on the other and so shaped to act as a "contractible jaw"--the jaw is elastically opened and then closed as it goes over the other tooth. The "snug fit" that results when "one member nests within the recess of an adjoining member" is a stable locked state. The maximum force when the slider operates is in between the unlocked and locked positions, giving two stable mechanical equilibria. The "snug fit" is stable not only to forces from wear that act in the same direction as those of the slider but to transverse and longitudinal (both perpendicular) forces.


title: Zipper

text: The zipper is analogous in mechanism to a bobby pin, where the person's hand slides hair into and out of the pin's "contractible jaw".


title: Zipper

text: Zippers have entered into urban legends. American folklorist Jan Brunvand noted that "The zipper has been the subject of jokes and legends since... the 1920s". Those stories reflect "modern anxieties and desires", emphasizing embarrassments and accidents, primarily involving the flies of men's trousers in stories such as "The Unzipped Stranger" and "The Unzipped Fly".


title: Zipper

text: The zipper is often the least durable component in any garment or type of equipment. Most often the zipper fails to close due to a worn or bent slider not being able to apply the necessary force to the sides of the teeth to cause them to interlock. This problem can sometimes be redressed by using small pliers to carefully squeeze the back part of the slider together a fraction of a millimeter. This can compensate for the wear of the slider. The slider is typically made as a magnesium diecast which breaks easily. It is necessary to reduce the force on the pliers before it can be felt that the slider actually gives in. If it is not yet possible to successfully close the zipper, the pressure applied to the slider should only gradually be increased. Another way to reduce the gap of the open end of the slider is by preparing a small block of wood by sawing a slot into one end so that it fits over the upper arm of the slider. Then a hammer can be used to exact a force onto the slider by carefully hitting the wood.


title: Zipper

text: When the protective coating of the diecast slider has been worn off by prolonged usage, the material can corrode. The corrosion products are usually metal salts which can accumulate and block the slider from moving. When this happens the salt can often be dissolved by submerging the slider in vinegar or another mild acid. Otherwise the slider needs to be removed and replaced.


title: Airborne forces

text: Airborne forces, airborne troops, or airborne infantry are ground combat units carried by aircraft and airdropped into battle zones, typically by parachute drop or air assault. Parachute-qualified infantry and support personnel serving in airborne units are also known as paratroopers.


title: Airborne forces

text: The main advantage of airborne forces is their ability to be deployed into combat zones without land passage, as long as the airspace is accessible. Formations of airborne forces are limited only by the number and size of their transport aircraft; a sizeable force can appear "out of the sky" behind enemy lines in merely hours if not minutes, an action known as "vertical envelopment".


title: Airborne forces

text: Airborne forces typically lack enough supplies for prolonged combat, so they are utilized for establishing an airhead to bring in larger forces before carrying out other combat objectives. Some infantry fighting vehicles have also been modified for paradropping with infantry to provide heavier firepower.


title: Airborne forces

text: Due to their necessary slow descent, paratroopers are vulnerable to anti-air fire from ground defenders, but combat jumps are at low altitude (400–500 ft) and normally carried out a short distance away (or directly on if lightly defended) from the target area at night. Airborne operations are also particularly sensitive to weather conditions, which can be dangerous to both the paratroopers and airlifters, so extensive planning is critical to the success of an airborne operation.


title: Airborne forces

text: Advances in VTOL technologies (helicopter and tiltrotor) since World War II have brought increased flexibility, and air assaults have largely been the preferred method of insertion for recent conflicts, but airborne insertion is still maintained as a rapid response capability to get troops on the ground anywhere in the world within hours for a variety of missions.


title: Airborne forces

text: Benjamin Franklin envisioned the danger of airborne attack in 1784, only a few months after the first manned flight in a hot air balloon:


title: Airborne forces

text: Although Winston Churchill proposed the creation of an airborne force to assault behind the German lines in 1917 during the First World War, the first modern operation was envisioned in late 1918. Major Lewis H. Brereton and his superior Brigadier General Billy Mitchell suggested dropping elements of the U.S. 1st Division behind German lines near Metz. The operation was planned for February 1919 but the war ended before the attack could be seriously planned. Mitchell conceived that US troops could be rapidly trained to utilize parachutes and drop from converted bombers to land behind Metz in synchronisation with a planned infantry offensive.


title: Airborne forces

text: Following the war, the United States Army Air Service experimented with the concept of carrying troops on the wings of aircraft, with them pulled off by the opening of their parachutes. The first true paratroop drop was by Italy in November 1927. Within a few years, several battalions were raised and eventually formed into two Folgore and Nembo divisions. Although they later fought with distinction in World War II, they were never used in a parachute drop. Men drawn from the Italian parachute forces were dropped in a special-forces operation in North Africa in 1943 in an attempt to destroy parked aircraft of the United States Army Air Forces.


title: Airborne forces

text: At about the same time, the Soviet Union was also experimenting with the idea, planning to drop entire units complete with vehicles and light tanks. To help train enough experienced jumpers, parachute clubs were organized with the aim of transferring into the armed forces if needed. Planning progressed to the point that Corps-size drops were demonstrated to foreign observers, including the British Military Attaché Archibald Wavell, in the Kiev military district maneuvers of 1935.


title: Airborne forces

text: One of the observing parties, Nazi Germany, was particularly interested. In 1936, Major F. W. Immans was ordered to set up a parachute school at Stendal (Borstel), and was allocated a number of Junkers Ju 52 aircraft to train on. The military had already purchased large numbers of Junkers Ju 52s which were slightly modified for use as paratroop transports in addition to their other duties. The first training class was known as "Ausbildungskommando Immans". They commenced the first course on May 3, 1936.


title: Airborne forces

text: Other nations, including Argentina, Peru, Japan, France and Poland also organized airborne units around this time. France became the first nation to organize women in an airborne unit, recruiting 200 nurses who during peacetime would parachute into natural disaster zones but also as reservists who would be a uniformed medical unit during wartime.


title: Airborne forces

text: Several groups within the German armed forces attempted to raise their own paratroop formations, resulting in confusion. As a result, Luftwaffe General Kurt Student was put in overall command of developing a paratrooper force to be known as the "Fallschirmjäger".


title: Airborne forces

text: During the invasions of Norway and Denmark in Operation Weserübung, the Luftwaffe dropped paratroopers on several locations. In Denmark, a small unit dropped on the Masnedøfort on the small island of Masnedø to seize the Storstrøm Bridge linking the islands of Falster and Zealand. A paratroop detachment also dropped at the airfield of Aalborg which was crucial for the Luftwaffe for operations over Norway. In Norway, a company of paratroopers dropped at Oslo's undefended airstrip. Over the course of the morning and early afternoon of April 9, 1940, the Germans flew in sufficient reinforcements to move into the capital in the afternoon, but by that time the Norwegian government had fled.

text: In the Battle of France, members of the Brandenburg Regiment landed by Fieseler Fi 156 Storch light reconnaissance planes on the bridges immediately to the south of the 10th Panzer Division's route of march through the southern Ardennes. In Belgium, a small group of German glider-borne troops landed on top of the Belgian fortress of Eben Emael on the morning of May 10, 1940, and disabled the majority of its artillery. The fort held on for another day before surrendering. This opened up Belgium to attack by German Army Group B.


title: Airborne forces

text: The Dutch were exposed to the first large scale airborne attack in history. During the invasion of the Netherlands, the Germans threw into battle almost their entire "Luftlandekorps", an airborne assault army corps that consisted of one parachute division and one division of airlanding troops plus the necessary transport capacity. The existence of this formation had been carefully kept secret until then. Two simultaneous airborne operations were launched. German paratroopers landed at three airfields near The Hague, hoping to seize the Dutch government. From one of these airfields, they were driven out after the first wave of reinforcements, brought in by Ju 52s, was annihilated by anti-aircraft fire and fierce resistance by some remaining Dutch defenders. As a result, numerous crashed and burning aircraft blocked the runway, preventing further reinforcements from landing. This was one of the few occasions where an airfield captured by paratroops has been recaptured. The other two airfields were recaptured as well. Simultaneously, the Germans dropped small packets of paratroopers to seize the crucial bridges that led directly across the Netherlands and into the heart of the country. They opened the way for the 9th Panzer Division. Within a day, the Dutch position became hopeless. Nevertheless, Dutch forces inflicted high losses on German transportation aircraft. Moreover, 1200 German elite troops from the "Luftlandekorps" taken prisoner around The Hague, were shipped to England just before the capitulation of the Dutch armed forces.


title: Airborne forces

text: The "Fallschirmjägers"' greatest victory and greatest losses occurred during the Battle of Crete. Signals intelligence, in the form of Ultra, enabled the British to wait on each German drop zone, yet despite compromised secrecy, surviving German paratroops and airlanded mountain troops pushed the Commonwealth forces off the island in part by unexpected fire support from their light 75 mm guns, though seaborne reinforcements were destroyed by the Royal Navy. However, the losses were so great that Adolf Hitler forbade their use in such operations in the future. He felt that the main strength of the paratroopers was novelty, and now that the British had clearly figured out how to defend against them, there was no real point to using them any more.


title: Airborne forces

text: One notable exception was the use of airborne forces in special operations. On September 12, 1943, Otto Skorzeny led a daring glider-based assault on the Gran Sasso Hotel, high in the Apennines mountains, and rescued Benito Mussolini from house arrest with very few shots being fired. On May 25, 1944, paratroopers were dropped as part of a failed attempt to capture Josip Broz Tito, the head of the Yugoslav Partisans and later postwar leader of Yugoslavia.


title: Airborne forces

text: Before the Pacific War began, the Imperial Japanese Army formed "Teishin Dan" ("Raiding Brigades") and the Imperial Japanese Navy trained marine ("Rikusentai") paratroopers. They used paratroops in several battles in the Dutch East Indies campaign of 1941–1942.


title: Airborne forces

text: "Rikusentai" airborne troops were first dropped at the Battle of Manado, Celebes in January 1942, and then near Usua, during the Timor campaign, in February 1942. "Teishin" made a jump at the Battle of Palembang, on Sumatra in February 1942. Japanese airborne units suffered heavy casualties during the Dutch East Indies campaign, and were rarely used as parachute troops afterward.


title: Airborne forces

text: On 6 December 1944, a 750-strong detachment from "Teishin Shudan" ("Raiding Division") and the "Takachiho" special forces unit, attacked U.S. airbases in the Burauen area on Leyte, in the Philippines. The force destroyed some planes and inflicted casualties, but was eventually wiped out.


title: Airborne forces

text: Ironically, the battle that ended Germany's paratrooper operations had the opposite effect on the Allies. Convinced of the effectiveness of airborne assaults after Crete, the Allies hurried to train and organize their own airborne units. The British established No.1 Parachute Training School at RAF Ringway near Manchester, which trained all 60,000 European paratroopers recruited by the Allies during World War II.


title: Airborne forces

text: An Airlanding School was also set up in New Delhi, India, in October/November 1941, at the then-Welllingdon Airport (now the defunct Safdarjang Airport) to train paratroopers for the British Indian Army which had been authorised to raise an airborne-capable formation earlier, resulting in the formation of the 50th Indian Parachute Brigade. The Indian airborne forces expanded during the war to the point that an airborne corps was planned bringing together the 2nd Indian Airborne Division and the British 6th Airborne Division, but the war ended before it could materialize.


title: Airborne forces

text: A fundamental decision was whether to create small airborne units to be used in specific coup-de-main type operations, or to organize entire airborne divisions for larger operations. Many of the early, successful airborne operations were small, carried out by a few units, such as seizing a bridge. After seeing success of other units and observing smokejumper training methods on how training can be done, ,in June 1940, General William C. Lee of the U.S. Army established the Army's first airborne division. The 101st world be reorganized into the 101st Airborne Division.


title: Airborne forces

text: The Allies eventually formed two British and five American divisions: the British 1st and 6th Airborne Divisions, and the U.S. 11th, 13th, 17th, 82nd, and 101st Airborne Divisions. By 1944, the British divisions were grouped into the 1st Airborne Corps under Lieutenant-General Sir Frederick Browning, while the American divisions in the European Theatre (the 17th, 82nd, and 101st) were organized into the XVIII Airborne Corps under Major General Matthew Ridgway. Both corps fell under the First Allied Airborne Army under U.S. Lieutenant General Lewis H. Brereton.


title: Airborne forces

text: The first U.S. airborne operation was by the 509th Parachute Infantry Battalion in November 1942, as part of Operation Torch in North Africa. The U.S. 82nd and 101st Airborne Divisions saw the most action in the European Theater, with the former in Sicily and Italy in 1943, and both in Normandy and the Netherlands in 1944. The 517th Parachute Regimental Combat Team was the principal force in Operation Dragoon in Southern France. The 17th Airborne Division deployed to England in 1944 but did not see combat until the Battle of the Bulge in January 1945 where they, along with the 82nd and 101st Airborne Divisions were deployed as ground troops.


title: Airborne forces

text: The U.S. 11th and 13th Airborne Divisions were held in reserve in the United States until 1944 when the 11th Airborne Division was deployed to the Pacific, but mostly used as ground troops or for smaller airborne operations. The 13th Airborne Division was deployed to France in January 1945 but never saw combat as a unit.


title: Airborne forces

text: The Soviets mounted only one large-scale airborne operation in World War II, despite their early leadership in the field in the 1930s. Russia also pioneered the development of combat gliders, but used them only for cargo during the war.


title: Airborne forces

text: Axis air superiority early in the conflict limited the ability of the Soviets to mount such operations, whilst later in the conflict ongoing shortages of materiel, including silk for parachutes, was also a problem. Nonetheless, the Soviets maintained their doctrinal belief in the effectiveness of airborne forces, as part of their concept of "deep battle", throughout the war. The largest drop during the war was corp-sized (the Vyazma airborne Operation, the 4th Airborne Corps). It was unsuccessful. Airborne formations were used as elite infantry units however, and played a critical role in several battles. For example, at the Battle of Kursk, the Guards Airborne defended the eastern shoulder of the southern penetration and was critical to holding back the German penetration.


title: Airborne forces

text: The Soviets sent at least one team of observers to the British and American airborne planning for D-Day, but did not reciprocate the liaison.


title: Airborne forces

text: Britain's first airborne assault took place on February 10, 1941, when 'X' Troop, No 11 Special Air Service Battalion (which was formed from No 2 Commando and subsequently became 1st Battalion, The Parachute Regiment) dropped into southern Italy from converted Whitley bombers flying from Malta and demolished a span of the aqueduct near Tragino in a daring night raid named Operation Colossus.


title: Airborne forces

text: 54 effectives of 'L' Detachment, Special Air Service Brigade (largely drawn from the disbanded Layforce) mounted a night parachute insertion onto two drop zones in Bir Temrad, North Africa on the night of November 16/17 1941 in preparation for a stealthy attack on the forward airfields of Gambut and Tmimi in order to destroy the Axis fighter force on the ground before the start of Operation Crusader, a major offensive by the British Eighth Army.


title: Airborne forces

text: A Würzburg radar site on the coast of France was attacked by a company of 120 British paratroopers from 2 Battalion, Parachute Regiment, commanded by Major John Frost, in Operation Biting on February 27, 1942. The key electronic components of the system were dismantled by an English radar mechanic and brought back to Britain for examination so that countermeasures could be devised. The result was a British victory. Of the 120 paratroopers who dropped in the dead of night, there were two killed, six wounded, and six captured.


title: Airborne forces

text: This was the last large-scale airborne assault by Hitler and the Germans. The German paratroopers had such a high casualty rate that Hitler forbade any further large-scale airborne attacks. The Allies, on the other hand, were very impressed by the potential of paratroopers, and started to build their own airborne divisions.


title: Airborne forces

text: The first United States airborne combat mission occurred during Operation Torch in North Africa on 8 November 1942. 531 men of the 2nd Battalion, 509th Parachute Infantry Regiment flew over at night from Britain, over Spain, intending to drop near Oran and capture two airfields. Navigation errors, communications problems, and bad weather scattered the forces. Seven of the 39 C-47s landed far from Oran from Gibraltar to Tunisia, and only ten actually delivered their troops by parachute drop. The remainder off-loaded after 28 C-47 troop carriers, short on fuel, landed on the Sebkra d'Oran dry lake, and marched overland to their objectives.


title: Airborne forces

text: One week later, after repacking their own chutes, 304 men of the battalion conducted a second combat jump on 15 November 1942 to secure the airfield at Youk-les-Bains near the Tunisian border. From this base, the battalion conducted combined operations with various French forces against the German Afrika Korps in Tunisia. A unit of French Algerian infantry, the 3rd Regiment of Zouaves, was present at Youk-les-Bains and awarded the American paratroopers their own regimental crest as a gesture of respect. This badge was awarded to the battalion commander on 15 November 1942 by the 3rd Zouaves' regimental commander, and is worn today by all members of the 509th Infantry.


title: Airborne forces

text: As part of Operation Husky, the Allied invasion of the island of Sicily, four airborne operations (two British and two American) were carried out, landing during the nights of July 9 and 10 1943. The American paratroopers were from the 82nd Airborne Division, mainly Colonel James Gavin's 505th Parachute Regimental Combat Team (consisting of the 3rd Battalion of the 504th PIR, Company 'B' of the 307th Airborne Engineer Battalion and the 456th Parachute Field Artillery Battalion, with other supporting units), making their first combat jump. Strong winds encountered en route blew the dropping aircraft off course and scattered them widely. The result was that around half the paratroopers failed to make it to their rallying points. The British airborne troops from the 1st Airborne Division were glider infantry of the 1st Airlanding Brigade, commanded by Brigadier Philip Hicks, and they fared little better. Only 12 out of 137 gliders in Operation Ladbroke landed on target, with more than half landing in the sea. Nevertheless, the scattered airborne troops maximised their opportunities, attacking patrols and creating confusion wherever possible. On the night of 11 July, a reinforcement drop of the 82nd, consisting of the 504th Parachute Regimental Combat Team (composed of the 1st and 2nd Battalions, the 376th Parachute Field Artillery and Company 'A' of the 307th Airborne Engineer Battalion), under Colonel Reuben Tucker, behind American lines at Farello airfield resulted in heavy friendly fire casualties when, despite forewarnings, Allied anti-aircraft fire both ashore and aboard U.S Navy ships shot down 23 of the transports as they flew over the beachhead.


title: Airborne forces

text: Despite a catastrophic loss of gliders and troops loads at sea, the British 1st Airlanding Brigade captured the Ponte Grande bridge south of Syracuse. Before the German counterattack, the beach landings took place unopposed and the 1st Airlanding Brigade was relieved by the British 5th Infantry Division as it swept inland towards Catania and Messina.


title: Airborne forces

text: On the evening of July 13, 1943, more than 112 aircraft carrying 1,856 men and 16 gliders with 77 artillerymen and ten 6 pounder guns, took off from North Africa in Operation Fustian. The initial target of the British 1st Parachute Brigade, under Brigadier Gerald Lathbury, was to capture the Primosole bridge and the high ground around it, providing a pathway for the Eighth Army, but heavy anti-aircraft fire shot down many of the Dakotas before they reached their target. Only 295 officers and men were dropped close enough to carry out the assault. They captured the bridge, but the German 4th Parachute Regiment recaptured it. They held the high ground until relieved by the 50th (Northumbrian) Infantry Division of the Eighth Army, which re-took the bridge at dawn on 16 July.


title: Airborne forces

text: The Allied commanders were forced to reassess the use of airborne forces after the many misdrops and the deadly friendly fire incident.


title: Airborne forces

text: General Dwight D. Eisenhower reviewed the airborne role in Operation Husky and concluded that large-scale formations were too difficult to control in combat to be practical. Lieutenant General Lesley J. McNair, the overall commander of Army Ground Forces, had similar misgivings: once an airborne supporter, he had been greatly disappointed by the performance of airborne units in North Africa and more recently Sicily. However, other high-ranking officers, including the Army Chief of Staff George Marshall, believed otherwise. Marshall persuaded Eisenhower to set up a review board and to withhold judgement until the outcome of a large-scale maneuver, planned for December 1943, could be assessed.


title: Airborne forces

text: McNair ordered 11th Airborne Division commander Major general Joseph May Swing to form a committee—the Swing Board—composed of air force, parachute, glider infantry and artillery officers, whose arrangements for the maneuver would effectively decide the fate of divisional-sized airborne forces. As the 11th Airborne Division was in reserve in the United States and had not yet been earmarked for combat, the Swing Board selected it as the test formation. The maneuver would additionally provide the 11th Airborne and its individual units with further training, as had occurred several months previously in an earlier large-scale exercise conducted by the 82nd and 101st Airborne Divisions.


title: Airborne forces

text: The 11th Airborne, as the attacking force, was assigned the objective of capturing Knollwood Army Auxiliary Airfield near Fort Bragg in North Carolina. The force defending the airfield and its environs was a combat team composed of elements of the 17th Airborne Division and a battalion from the 541st Parachute Infantry Regiment. The entire operation was observed by McNair, who would ultimately have a significant say in deciding the fate of the parachute infantry divisions.


title: Airborne forces

text: The Knollwood Maneuver took place on the night of 7 December 1943, with the 11th Airborne Division being airlifted to thirteen separate objectives by 200 C-47 Skytrain transport aircraft and 234 Waco CG-4A gliders. The transport aircraft were divided into four groups, two of which carried paratroopers while the other two towed gliders. Each group took off from a different airfield in the Carolinas. The four groups deployed a total of 4,800 troops in the first wave. Eighty-five percent were delivered to their targets without navigational error, and the airborne troops seized the Knollwood Army Auxiliary Airfield and secured the landing area for the rest of the division before daylight. With its initial objectives taken, the 11th Airborne Division then launched a coordinated ground attack against a reinforced infantry regiment and conducted several aerial resupply and casualty evacuation missions in coordination with United States Army Air Forces transport aircraft. The exercise was judged by observers to be a great success. McNair, pleased by its results, attributed this success to the great improvements in airborne training that had been implemented in the months following Operation Husky. As a result of the Knollwood Maneuver, division-sized airborne forces were deemed to be feasible and Eisenhower permitted their retention.


title: Airborne forces

text: Italy agreed to an armistice with the Allies on September 3, 1943, with the stipulation that the Allies would provide military support to Italy in defending Rome from German occupation. Operation Giant II was a planned drop of one regiment of the U.S. 82nd Airborne Division northwest of Rome, to assist four Italian divisions in seizing the Italian capital. An airborne assault plan to seize crossings of the Volturno river during the Allied invasion of Italy, called Operation Giant, was abandoned in favor of the Rome mission. However, doubts about the willingness and capability of Italian forces to cooperate, and the distance of the mission far beyond support by the Allied military, resulted in the 82nd Airborne artillery commander, Brigadier General Maxwell Taylor (future commander of the 101st Airborne Division), being sent on a personal reconnaissance mission to Rome to assess the prospects of success. His report via radio on September 8 caused the operation to be postponed (and canceled the next day) as troop carriers loaded with two battalions of the 504th PIR were warming up for takeoff.


title: Airborne forces

text: With Giant II cancelled, Operation Giant I was reactivated to drop two battalions of the 504th PIR at Capua on September 13. However, significant German counterattacks, beginning on September 12, resulted in a shrinking of the American perimeter and threatened destruction of the Salerno beachhead. As a result, Giant I was cancelled and the 504th PIR instead dropped into the beachhead on the night of September 13 using transponding radar beacons as a guide. The next night the 505th PIR was also dropped into the beachhead as reinforcement. In all, 3,500 paratroopers made the most concentrated mass night drop in history, providing the model for the American airborne landings in Normandy in June 1944. An additional drop on the night of September 14–15 of the 509th PIB to destroy a key bridge at Avellino, to disrupt German motorized movements, was badly dispersed and failed to destroy the bridge before the Germans withdrew to the north.


title: Airborne forces

text: In April 1945, Operation Herring, an Italian commando-style airborne drop aimed at disrupting German rear area communications and movement over key areas in Northern Italy, took place. However the Italian troops were not dropped as a unit, but as a series of small (8–10 man) groups. Another operation, Operation Potato, was mounted by men drawn from the Folgore and Nembo divisions, operating with British equipment and under British command as No. 1 Italian Special Air Service Regiment. The men dropped in small groups from American C-47s and carried out a successful railway sabotage operation in northern Italy.


title: Airborne forces

text: The Allies had learned better tactics and logistics from their earlier airborne drops, and these lessons were applied for the assaults along the Western Front.


title: Airborne forces

text: One of the most famous of airborne operations was Operation Neptune, the assault of Normandy, part of Operation Overlord of the Normandy landings on June 6, 1944. The task of the airborne forces was to secure the flanks and approaches of the landing beaches in Normandy. The British glider transported troops and paratroopers of the 6th Airborne Division, which secured the eastern flank during Operation Tonga. This operation included the capture of the Caen canal and Orne river bridges, and the attack on the Merville gun battery. The American glider and parachute infantry of the 82nd (Operation Detroit) and 101st Airborne Divisions (Operation Chicago), though widely scattered by poor weather and poorly marked landing zones in the American airborne landings in Normandy, secured the western flank of U.S. VII Corps with heavy casualties. All together, airborne casualties in Normandy on D-Day totaled around 2,300.


title: Airborne forces

text: Operation Dingson (5–18 June 1944) was conducted by about 178 Free French paratroops of the 4th Special Air Service (SAS), commanded by Colonel Pierre-Louis Bourgoin, who jumped into German-occupied France near Vannes, Morbihan, southern Brittany, in Plumelec, at 1130 on the night of 5 June and Saint-Marcel (8–18 June). At this time, there was approximately 100,000 German troops and artillery preparing to move to the Normandy landing areas. Immediately upon landing, 18 Free French went into action near Plumelec against German troops (Vlassov's army). The Free French established a base at Saint-Marcel and began to arm and equip local resistance fighters, operating with up to 3,000 Maquis. However, their base was heavily attacked by a German paratroop division on 18 June, and the men were forced to disperse. Captain Pierre Marienne with 17 of his companions (six paratroopers, eight resistance fighters and three farmers) died a few weeks later in Kerihuel, Plumelec, at dawn of 12 July. The Dingson team was joined by the men who had just completed Operation Cooney. Dingson was conducted alongside Operation Samwest and Operation Lost as part of Overlord.


title: Airborne forces

text: In Operation Dingson 35A, on 5 August 1944, 10 Waco CG-4A gliders towed by aircraft of 298 Squadron and 644 Squadron transported Free French SAS men and armed jeeps to Brittany near Vannes (Locoal-Mendon), each glider carrying three Free French troopers and a jeep. One glider was lost with the death of the British pilot. The SAS teams remained behind enemy lines until the Allies arrived.


title: Airborne forces

text: On August 15, 1944, airborne units of the 6th Army Group provisional airborne division, commanded by U.S. Major General Robert T. Frederick, opened Operation Dragoon, the invasion of Southern France, with a dawn assault. Called the "1st Airborne Task Force", the force was composed of the 1st Special Services Forces, British 2nd Independent Parachute Brigade, the 517th Parachute Regimental Combat Team, the 509th and 551st Parachute Infantry Battalions, the glider-borne 550th Airborne Infantry Battalion, and supporting units. Nearly 400 aircraft delivered 5,600 paratroopers and 150 guns to three drops zones surrounding Le Muy, between Fréjus and Cannes, in phase 1, Operation Albatross. Once they had captured their initial targets, they were reinforced by 2,600 soldiers and critical equipment carried in 408 gliders daylight missions code-named Operation Bluebird, phase 2, simultaneous with the beach landings, and Operation Dove, phase 3. A second daylight parachute drop, Operation Canary, dropped 736 men of the 551st PIB with nearly 100% effectiveness late on the afternoon of August 15. The airborne objective was to capture the area, destroy all enemy positions and hold the ground until the U.S. Seventh Army came ashore.


title: Airborne forces

text: Operation Market Garden of September 1944, involved 35,000 airborne troops dropped up to behind German lines in an attempt to capture a series of bridges over the Maas, Waal and Rhine Rivers, in an attempt to outflank German fortifications and penetrate into Germany. The operation was hastily planned and many key planning tasks were inadequately completed. Three complete airborne divisions executed Operation Market, the airborne phase. These were the British 1st Airborne Division, the U.S. 82nd and 101st Airborne Divisions, as well as the Polish 1st Independent Parachute Brigade. All units were landed or dropped at various points along Highway 69 ("Hell's Highway") in order to create a "carpet" over which the British XXX Corps could rapidly advance in Operation Garden, the land phase. It was a daylight assault, with little initial opposition, and most units achieved high accuracy on drop and landing zones. In the end, after strong German counterattacks, the overall plan failed: the British 1st Airborne Division was all but destroyed at Arnhem, and the final Rhine bridge remained in German hands.


title: Airborne forces

text: Operation Repulse, which took place in Bastogne on December 23, 24, 26, and 27, 1944, as part of the Battle of the Bulge, glider pilots, although flying directly through enemy fire, were able to land, delivering the badly needed ammunition, gasoline and medical supplies that enabled defenders against the German offensive to persevere and secure the ultimate victory.


title: Airborne forces

text: Operation Varsity was a daylight assault conducted by two airborne divisions, the British 6th Airborne Division and the U.S. 17th Airborne Division, both of which were part of the U.S. XVIII Airborne Corps. Conducted as a part of Operation Plunder, the operation took place on 24 March 1945 in aid of an attempt by the Anglo-Canadian 21st Army Group to cross the Rhine River. Having learnt from the heavy casualties inflicted upon the airborne formations in Operation Market Garden, the two airborne divisions were dropped several thousand yards forward of friendly positions, and only some thirteen hours after Operation Plunder had begun and Allied ground forces had already crossed the Rhine. There was heavy resistance in some of the areas that the airborne troops landed in, with casualties actually statistically heavier than those incurred during Operation Market Garden. The British military historian Max Hastings has labelled the operation both costly and unnecessary, writing that "Operation Varsity was a folly for which more than a thousand men paid for with their lives ..."


title: Airborne forces

text: In September 1943, in New Guinea, the U.S. Army's 503rd Parachute Infantry Regiment and elements of the Australian Army's 2/4th Field Regiment made a highly successful, unopposed landing at Nadzab, during the Salamaua-Lae campaign. This was the first Allied airborne assault in the Pacific Theater.


title: Airborne forces

text: In July 1944, the 503rd jumped again, onto Noemfoor Island, off Dutch New Guinea, in the Battle of Noemfoor.


title: Airborne forces

text: The honors for recapturing the Rock went to the 503rd Parachute Regimental Combat Team of Lieutenant Colonel George M. Jones and elements of Major General Roscoe B. Woodruff's 24th Infantry Division, the same units which undertook the capture of Mindoro island. The U.S. 503rd Parachute Infantry Regiment's most famous operation was a landing on Corregidor ("The Rock") in February 1945, during the Philippines campaign of 1944–45.


title: Airborne forces

text: The U.S. Army's 11th Airborne Division saw a great deal of action in the Philippines as a ground unit. The 511th Parachute Infantry Regiment made the division's first jump near Tagaytay Ridge on 3 February 1945, meeting no resistance at the drop zone. Elements of the division also jumped to liberate 2,000 Allied civilians interned at Los Baños, 23 February 1945. The final operation of the division was conducted on 23 June 1945, in conjunction with an advance by U.S. ground forces in northern Luzon. A task force from the 11th was formed and jumped on Camalaniugan Airfield, south of Aparri.


title: Airborne forces

text: A large British force, known as the Chindits, operated behind Japanese lines during 1944. In Operation Thursday, most of the units were flown into landing grounds which had been seized by glider infantry transported by the American First Air Commando Group, commencing on March 5. Aircraft continued to land reinforcements at captured or hastily constructed landing strips until monsoon rains made them unusable. Small detachments were subsequently landed by parachute. The operation eventually wound down in July, with the exhausted Chindits making their way overland to link up with advancing American and Chinese forces.


title: Airborne forces

text: For Operation Dracula, an ad hoc parachute battalion group made up of personnel from the 153 and 154 (Gurkha) Parachute Battalions of the Indian Army secured Japanese coastal defences, which enabled the seaborne assault by the 26th Indian Infantry Division to attain its objectives with a minimum of casualties and time.


title: Airborne forces

text: During the Ecuadorian–Peruvian War, the Peruvian army established its own paratrooper unit and used it to great effect by seizing the Ecuadorian port city of Puerto Bolívar, on July 27, 1941, marking the first time in the Americas that airborne troops were used in combat.


title: Airborne forces

text: The Dutch Korps Speciale Troepen made two combat jumps during the Indonesian War of Independence. The first jump was as part of Operation Kraai: the capture of Yogyakarta, and the capture of Sukarno and Mohammad Hatta on 19 and 20 December 1948.


title: Airborne forces

text: The second combat jump happened during Operation Ekster: the capture of Jambi and the oilfields surrounding is, on Sumatra from 29 December 1948 to 23 January 1949. From the Indonesian side, the first airborne operation was an airborne-infiltration operation by 14 paratroopers on 17 October 1947, in Kotawaringin, Kalimantan.


title: Airborne forces

text: The 187th Airborne Regimental Combat Team ("Rakkasans") made two combat jumps in Korea during the Korean War. The first combat jump was made on October 20, 1950, at Sunchon and Sukchon, North Korea. The missions of the 187th were to cut the road north going to China, preventing North Korean leaders from escaping from Pyongyang; and to rescue American prisoners of war.


title: Airborne forces

text: The second combat jump was made on Wednesday, March 21, 1951, at Munsan-ni, South Korea codenamed Operation Tomahawk. The mission was to get behind Chinese forces and block their movement north. The 60th Indian Parachute Field Ambulance provided the medical cover for the operations, dropping an ADS and a surgical team totalling 7 officers and 5 other ranks, treating over 400 battle casualties apart from the civilian casualties that formed the core of their objective as the unit was on a humanitarian mission. The unit was to become the longest-serving military unit in any UN operation till date, serving from October 1950 till May 1953, a total of three and a half years, returning home to a heroes' welcome.


title: Airborne forces

text: The 187th served in six campaigns in Korea. Shortly after the war the 187th ARCT was considered for use in an Airborne drop to relieve the surrounded French garrison at Dien Bien Phu in Vietnam but the United States, at that time, decided not to send its troops into the combat zone.


title: Airborne forces

text: The unit was assigned to the reactivated 101st Airborne Division and subsequently inactivated as a combat team in 1956 as part of the division's reorganization into the Pentomic structure, which featured battle groups in place of regiments and battalions. The 1st and 3rd Battalions, 187th Infantry, bearing the lineages of the former Co A and Co C, 187AIR, are now with the 101st Airborne Division as air assault units.


title: Airborne forces

text: The French used paratroopers extensively during their 1946-54 war against the Viet Minh. Troupes de marine, Foreign Legion and local Vietnamese units took part in numerous operations which were to culminate in the disastrous siege of Dien Bien Phu.


title: Airborne forces

text: Launching the 1956 Suez War, on October 29, 1956, Israeli paratroopers led by Ariel Sharon dropped onto the important Mitla Pass to cut off and engage Egyptian forces. "Operation Machbesh" (Press) was the IDF's first and largest combat parachute drop.

text: A few days later, Operation Musketeer needed the element of total surprise to succeed, and all 660 men had to be on the ground at El Gamil airfield and ready for action within four and a half minutes. At 04.15 hours on November 5, 1956, British 3rd Battalion, Parachute Regiment jumped in and although opposition was heavy, casualties were few. Meanwhile, French paratroopers of the 2nd Marine Infantry Parachute Regiment under the command of Colonel Chateau-Jobert jumped on the water treatment factory South of Port Said.

text: The landings from the sea the next day saw the first large-scale heliborne assault, as 45 Commando, Royal Marines were landed by helicopters in Port Said from ships offshore. Both the British and the French accomplished total military victory against the disorganized Egyptian military and local armed civilians but political events forced total retreat of these forces after 48 hours of fighting.

text: Paratroopers were first used in combat in South Asia during the Indo-Pakistani War of 1965. A covert operation was launched by the Pakistani Army with the intention of infiltrating Indian airbases and sabotaging them. The SSG (Special Service Group) commandos, were parachuted into Indian territory. Of the 180 para-commandos dropped, 138, including all officers but one, were captured and safely taken to prisoner of war (POW) camps. Twenty-two were killed, or rather lynched by joint combing teams of villagers armed with sticks, police and even bands of muleteers released by the Army, from the animal transport battalion of the nearby Corps headquarters.


title: Airborne forces

text: Only 20 para-commandos were unaccounted for and most escaped back to Pakistan under the fog. Most of these were from the Pathankot group, dropped less than 10 km from the border in an area that had plenty of ravines, riverine tracks to navigate back along.

text: During the Bangladesh Liberation War of 1971, the Parachute Regiment of the Indian Army fought in numerous contacts in both the Eastern and Western Theatres. On 11 December, India airdropped the 2nd battalion (2 Para) in what is now famous as the Tangail airdrop. The paratroop unit was instrumental in denying the retreat and regrouping of the Pakistani Army and contributed substantially to the early collapse of Dhaka via covert operations. The regiment earned the battle honours of Poongli Bridge, Chachro and Defence of Poonch—during these operations.

text: The Indonesian Army used airborne troops in their 1975 invasion of East Timor. Following a naval bombardment of Dili, on December 7, 1975, Indonesian seaborne troops landed in the city while paratroops simultaneously descended on the city. 641 Indonesian paratroopers jumped into Dili, where they engaged in six-hours combat with East Timorese gunmen.

text: In 1963, in the Battle of Ap Bac, ARVN forces delivered airborne troops by helicopter and air drop. The use of helicopter-borne airmobile troops by the United States Army in the Vietnam War was widespread, and became an iconic image featuring in newsreels and movies about the conflict.

text: In February 1967 Operation Junction City was launched, it would be the largest operation the Allied forces would assemble. During this operation, 845 members of the 2nd Battalion, 503rd Airmen (Airborne), the 319th Artillery (Airborne), and elements of H&H company of the 173rd Airborne Brigade made the only combat jump in Vietnam.


title: Airborne forces

text: The men of the Rhodesian Light Infantry made more parachute jumps than any other military unit in history. While an Allied paratrooper of the Second World War would be considered a "veteran" after one operational jump, an RLI paratrooper could make three operational jumps in a single day, each in a different location, and each preceding a successful contact with the enemy. Between 1976 and 1980, over 14,000 jumps were recorded by the Rhodesian Security Forces as a whole.


title: Airborne forces

text: The world record for operational jumps by an individual soldier is held by Corporal Des Archer of 1 Commando, RLI, who made 73 operational jumps between 1977 and the end of the war.


title: Airborne forces

text: Fireforce is a variant of the tactic of vertical envelopment of a target by helicopter-borne and small groups of parachute infantry developed by the Rhodesian Security Force.


title: Airborne forces

text: Fireforce counter-insurgency missions were designed to trap and eliminate insurgents before they could flee. The Rhodesian Security Force could react quickly to insurgent ambushes, farm attacks, Observation Post sightings, and could also be called in as reinforcements by trackers or patrols which made contact with the enemy. It was first deployed in January 1974 and saw its first action a month later on 24 February 1974. By the end of Rhodesian operations with internal peace agreements, Fireforce was a well-developed counterinsurgency tactic.


title: Airborne forces

text: Fireforce was an operational assault or response usually composed of a first wave of 32 soldiers carried to the scene by three Alouette III helicopters and one Dakota transport aircraft, with another Alouette III helicopter as a command/gunship aircraft and a light attack aircraft in support. One of the advantages of the Fireforce was its flexibility as all that was needed was a reasonable airstrip. It was such a successful tactic that some Rhodesian Light Infantry soldiers reputedly made as many as three parachute combat jumps in one day.

text: During the War in Angola, paratroopers of the South African Army attacked a South West Africa People's Organization (SWAPO) military base at the former town of Cassinga, Angola on 4 May 1978. Conducted as one of the three major actions of Operation Reindeer during the South African Border War, it was the South African Army's first major air assault.


title: Airborne forces

text: The Soviet Union maintained the world's largest airborne force during the Cold War, consisting of seven airborne divisions and a training division. The VDV was subordinated directly to the Ministry of Defense of USSR, and was a 'prestige service' in the armed forces of the USSR and Russia to reflect its strategic purpose. Recruits received much more rigorous training and better equipment than ordinary Soviet units. Unlike most airborne forces, which are a light infantry force, VDV has evolved into a "fully mechanized" parachute-deployed force thanks to its use of BMD-series light IFVs, BTR-D armoured carriers, 2S9 Nona self-propelled 120 mm gun-howitzer-mortars and 2S25 Sprut-SD 125 mm tank destroyers.


title: Airborne forces

text: The VDV have participated in virtually all Soviet and Russian conflicts since the Second World War, including the Soviet–Afghan War. As an elite force, the VDV developed two distinctive items of clothing: the "telnyashka", or striped shirt, and the famous blue beret. Airborne assault (десантно-штурмовые войска or DShV) units wore similar striped shirts (as did the naval infantry) but used helicopters, rather than the Military Transport Aviation's An-12s, An-22s, and Il-76s, which carried the airborne troops and their equipment.

text: Operation Meghdoot ( "Operation Cloud Messenger"), launched in the early hours of 13 April 1984, was the codename given to the preemptive strike launched by the Indian Armed Forces' to gain control of the Siachen Glacier in Kashmir, precipitating the Siachen conflict.


title: Airborne forces

text: Executed in the highest battlefield in the world, Meghdoot was the first ever military offensive of its kind. The operation was a success, resulting in Indian forces gaining control of the Siachen Glacier in its entirety.


title: Case Blue

text: Case Blue (German: "Fall Blau") was the German Armed Forces' plan for the 1942 strategic summer offensive in southern Russia between 28 June and 24 November 1942, during World War II. The objective was to capture the oil fields of Baku (Azerbaijan SSR), Grozny and Maikop for two purposes: to enable the Germans to re-supply their low fuel stock and also to deny their use to the Soviet Union, thereby bringing about the complete collapse of the Soviet war effort.


title: Case Blue

text: After Operation Barbarossa failed to destroy the Soviet Union as a political and military threat the previous year, Adolf Hitler, the "Führer" of Nazi Germany, recognised that Germany was now locked in a war of attrition, and he was also aware that Germany was running low on fuel supply and would not be able to continue attacking deeper into enemy territory without more stock. With this in mind, Hitler ordered for the preparation of offensive plans for summer 1942 to secure the Soviet oil fields in the Caucasus. The operation involved a two-pronged attack: one from the Axis right flank against the oil fields of Baku, known as Operation Edelweiss, and one from the left flank to protect the first attack, moving in the direction of Stalingrad along the Don River, known as Operation Fischreiher.


title: Case Blue

text: Army Group South ("Heeresgruppe Süd") of the German Army was divided into Army Groups A and B ("Heeresgruppe A" and "B"). Army Group A was tasked with fulfilling Operation Edelweiss by crossing the Caucasus mountains to reach the Baku oil fields, while Army Group B protected its flanks along the Volga by fulfilling Operation Fischreiher.


title: Case Blue

text: Supported by 2,035 Luftwaffe aircraft and 1,934 tanks and assault guns, the 1,570,287-man Army Group South began the offensive on 28 June, advancing 48 kilometers on the first day and easily brushing aside the 1,715,000 Red Army troops opposite, who falsely expected a German offensive on Moscow even after "Blau" commenced. The Soviet collapse in the south allowed the Germans to capture the western part of Voronezh on 6 July and reach and cross the Don river near Stalingrad on 26 July. Army Group B's approach toward Stalingrad slowed in late July and early August owing to constant counterattacks by newly deployed Red Army reserves and overstretched German supply lines. The Germans defeated the Soviets in the Battle of Kalach and the combat shifted to the city itself in late August. Nonstop Luftwaffe airstrikes, artillery fire and street-to-street combat completely destroyed the city and inflicted heavy casualties on the opposing forces. After three months of battle, the Germans controlled 90% of Stalingrad on 19 November.


title: Case Blue

text: In the south, Army Group A captured Rostov on 23 July and swept south from the Don to the Caucasus, capturing the demolished oilfields at Maikop on 9 August and Elista on 13 August near the Caspian Sea coast. Heavy Soviet resistance and the long distances from Axis sources of supply reduced the Axis offensive to local advances only and prevented the Germans from completing their strategic objective of capturing the main Caucasus oilfield at Baku. Luftwaffe bombers destroyed the oilfields at Grozny but attacks on Baku were prevented by the insufficient range of the German fighters.


title: Case Blue

text: The Allies were concerned about the possibility of German forces continuing to the south and east and linking up with Japanese forces (then advancing in Burma) in India. However, the Red Army defeated the Germans at Stalingrad, following Operations Uranus and Little Saturn. This defeat forced the Axis to retreat from the Caucasus in order to avoid getting cut off by the Red Army, which was now advancing from Stalingrad towards Rostov in order to achieve the cut-off. Only the Kuban region remained tentatively occupied by Axis troops.


title: Case Blue

text: On 22 June 1941, Germany launched Operation Barbarossa with the intention of defeating the Soviet Union in a quick offensive which was expected to last only 3 months. The Axis offensive had met with initial success and the Red Army had suffered some major defeats before halting the Axis units just short of Moscow (November/December 1941). Although the Germans had captured vast areas of land and important industrial centers, the Soviet Union remained in the war. In the winter of 1941–42, the Soviets struck back in a series of successful counteroffensives, pushing back the German threat to Moscow. Despite these setbacks, Hitler wanted complete destruction of Russia, for which he required the oil resources of the Caucasus. By February 1942 the German Army High Command (OKH) had begun to develop plans for a follow-up campaign to the aborted Barbarossa offensive – with the Caucasus as its principal objective. On 5 April 1942, Hitler laid out the elements of the plan now known as "Case Blue" ("Fall Blau") in "Führer Directive" "No. 41". The directive outlined the main goals of the 1942 summer campaign on Germany's Eastern Front: holding attacks for Army Group (AG) Centre, the capture of Leningrad and the link-up with Finland for AG North, and the capture of the Caucasus region for Army Group South. The main focus was to be the capture of the Caucasus region.


title: Case Blue

text: The Caucasus, a large, culturally diverse region traversed by its eponymous mountains, is bounded by the Black Sea to the west and the Caspian Sea to the east. The region north of the mountains was a production center for grain, cotton and heavy farm machinery, while its two main oilfields, at Maykop, near the Black Sea, and Grozny, about halfway between the Black and the Caspian Seas, produced about 10 percent of all Soviet oil. South of the mountains lay Transcaucasia, comprising Georgia, Azerbaijan and Armenia. This heavily industrialized and densely populated area contained some of the largest oilfields in the world. Baku, the capital of Azerbaijan, was one of the richest, producing 80 percent of the Soviet Union's oil—about 24 million tons in 1942 alone.


title: Case Blue

text: The Caucasus also possessed plentiful coal and peat, as well as nonferrous and rare metals. Manganese deposits at Chiatura, in Transcaucasia, formed the richest single source in the world, yielding 1.5 million tons of manganese ore annually, half of the Soviet Union's total production. The Kuban region of the Caucasus also produced large amounts of wheat, corn, sunflower seeds, and sugar beets, all essential in the production of food.


title: Case Blue

text: These resources were of immense importance to Hitler and the German war effort. Of the three million tons of oil Germany consumed per year, 85 percent was imported, mainly from the United States, Venezuela, and Iran. When war broke out in September 1939, the British naval blockade cut Germany off from the Americas and the Middle East, leaving the country reliant on oil-rich European countries such as Romania to supply the resource. An indication of German reliance on Romania is evident from its oil consumption; in 1938, just one-third of the 7,500,000 tons consumed by Germany came from domestic stocks. Oil had always been Germany's Achilles heel, and by the end of 1941, Hitler had nearly exhausted Germany's reserves, which left him with only two significant sources of oil, the country's own synthetic production and the Romanian oilfields, with the latter supplying 75% of Germany's oil imports in 1941. Aware of his declining oil resources, and fearful of enemy air attacks on Romania (Germany's main source of crude oil), Hitler's strategy was increasingly driven by the need to protect Romania and acquire new resources, essential if he wanted to continue waging a prolonged war against a growing list of enemies. In late 1941, the Romanians warned Hitler that their stocks were exhausted and they were unable to meet German demands. For these reasons, the Soviet oilfields were extremely important to Germany's industry and armed forces as the war became global, the power of the Allies grew, and shortages started to occur in Axis resources.


title: Case Blue

text: The strategic objectives of the operation were the oilfields at Maykop, Grozny and Baku. As in Barbarossa, these movements were expected to result in a series of grand encirclements of Soviet troops.


title: Case Blue

text: The offensive was to be conducted across the southern Russian (Kuban) steppe utilizing the following Army Group units:


title: Case Blue

text: The Soviet army command ("Stavka") failed to discern the direction of the main German strategic offensive anticipated in 1942, even though they were in possession of the German plans. On 19 June, the chief of operations of the 23rd Panzer Division, Major Joachim Reichel, was shot down over Soviet-held territory while flying an observation aircraft over the front near Kharkov. The Soviets recovered maps from his aircraft detailing the exact German plans for Case Blue. The plans were handed over to "Stavka", in Moscow.


title: Case Blue

text: Joseph Stalin, however, believed it to be a German ruse, remaining convinced that the primary German strategic goal in 1942 would be Moscow, in part due to Operation Kremlin ("Fall Kreml"), a German deception plan aimed at the city. As a result, the majority of Red Army troops were deployed there, although the direction from which the Case Blue offensive would come was still defended by the Bryansk, Southwestern, Southern and North Caucasian Fronts. With about 1 million soldiers at the front line and another 1.7 million in reserve armies, their forces accounted for about one quarter of all Soviet troops. Following the disastrous start of Case Blue for the Soviets, they reorganised their frontlines several times. Over the course of the campaign, the Soviets also fielded the Voronezh Front, Don Front, Stalingrad Front, Transcaucasian Front, and the Caucasian Front, though not all existed at the same time.


title: Case Blue

text: With the German thrust expected in the north, "Stavka" planned several local offensives in the south to weaken the Germans. The most important of these was aimed at the city of Kharkov and would be conducted mainly by the Southwestern Front under Semyon Timoshenko, supported by the Southern Front commanded by Rodion Malinovsky. The operation was scheduled for 12 May, just prior to a planned German offensive in the area. The ensuing Second Battle of Kharkov ended in disaster for the Soviets, severely weakening their mobile forces. At the same time, the Axis clearing of the Kerch Peninsula together with the Battle of Sevastopol, which lasted until July, weakened the Soviets further and allowed the Germans to supply Army Group A across the Kerch Peninsula through the Kuban.


title: Case Blue

text: The German offensive commenced on 28 June 1942, with Fourth Panzer Army starting its drive towards Voronezh. Due to a chaotic Soviet retreat, the Germans were able to advance rapidly, restoring "Wehrmacht" confidence for the upcoming major offensive.


title: Case Blue

text: Close air support from the Luftwaffe also played an important role in this early success. It contained the Red Air Force, through air superiority operations, and provided interdiction through attacks on airfields and Soviet defence lines. At times, the German air arm acted as a spearhead rather than a support force, ranging on ahead of the tanks and infantry to disrupt and destroy defensive positions. As many as 100 German aircraft were concentrated on a single Soviet division in the path of the spearhead during this phase. General Kazakov, the Bryansk Front's chief of staff, noted the strength and effectiveness of the Axis aviation. Within 26 days, the Soviets lost 783 aircraft from the 2nd, 4th, 5th and 8th Air Armies, compared to a German total of 175.


title: Case Blue

text: By 5 July, forward elements of Fourth Panzer Army had reached the Don River near Voronezh and became embroiled in the battle to capture the city. Stalin and the Soviet command still expected the main German thrust in the north against Moscow, and believed the Germans would turn north after Voronezh to threaten the capital. As a result, the Soviets rushed reinforcements into the town to hold it at all costs and counterattacked the Germans' northern flank in an effort to cut off the German spearheads. 5th Tank Army, commanded by Major General A.I. Liziukov, managed to achieve some minor successes when it began its attack on 6 July, but was forced back to its starting positions by 15 July, losing about half of its tanks in the process. Although the battle was a success, Hitler and von Bock, commander of Army Group South, argued over the next steps in the operation. The heated debate, and continuing Soviet counterattacks, which tied down Fourth Panzer Army until 13 July, caused Hitler to lose his temper and dismiss von Bock on the 17th of July. As part of the second phase of the operation, on 9 July, Army Group South was split into Army Group A and Army Group B, with Wilhelm List appointed as commander of Army Group A and Army Group B commanded by Maximillian von Weichs.


title: Case Blue

text: Only two weeks into the operation, on 11 July, the Germans began to suffer logistical difficulties, which slowed the advance. The German Sixth Army was continually delayed by fuel shortages. Eight days later, on 20 July, shortages of fuel were still undermining operations, leaving many units unable to execute their orders. The 23rd Panzer Division and 24th Panzer Division both became stranded during the opening phase. Once again, as it had done during the Norwegian Campaign in April 1940, and "Barbarossa" in 1941, the Luftwaffe's Junkers Ju 52 transport fleet flew in supplies to keep the army going. The situation remained difficult with German troops forced to recover fuel from damaged or abandoned vehicles, and in some cases, leave behind tanks and vehicles with heavy fuel consumption to continue their advance. This undermined the strength of the units, which were forced to leave fighting vehicles behind. Nevertheless, the Luftwaffe flew in 200 tons of fuel per day to keep the army supplied. Despite this impressive performance in keeping the army mobile, Löhr was replaced by the more impetuous and offensive-minded von Richthofen.


title: Case Blue

text: Believing that the main Soviet threat had been eliminated, desperately short of oil and needing to meet all the ambitious objectives of Case Blue, Hitler made a series of changes to the plan in "Führer" Directive No. 45 on July 23, 1942:


title: Case Blue

text: There is no evidence Hitler was opposed by, or received complaints from Franz Halder, Chief of the General Staff, or anyone else, about the directive until August 1942. The new directive created enormous logistical difficulties, with Hitler expecting both Army Groups to advance along different routes. Logistics lines were already at breaking point with ammunition and fuel shortages most apparent and it would be impossible to advance using the conservative supply rates he demanded. The divergence of the Army Groups would also open a dangerous gap between the Armies, which could be exploited by the Soviets. The Italian Alpine Corps, of the Italian Army in the Soviet Union, did not arrive in the Caucasus Mountains with Army Group A, instead remaining with Sixth Army. Army Group A was expected to operate in mountain terrain with only three mountain divisions and two infantry divisions unsuited to the task.


title: Case Blue

text: The splitting of Army Group South enabled the launching of Operation Edelweiss and Operation Fischreiher, the two main thrusts of the Army Groups. Both groups had to achieve their objectives simultaneously, instead of consecutively. The success of the initial advance was such that Hitler ordered the Fourth Panzer Army south to assist the First Panzer Army to cross the lower Don river. This assistance was not needed and Kleist later complained that Fourth Panzer Army clogged the roads and that if they had carried on toward Stalingrad, they could have taken it in July. When it turned north again two weeks later, the Soviets had gathered enough forces together at Stalingrad to check its advance.


title: Case Blue

text: With air support from the Ju 87s of "Sturzkampfgeschwader 77", List's Army Group A recaptured Rostov, the "gate to the Caucasus", on 23 July 1942 relatively easily. The "Luftwaffe" had air superiority in the early phase of the operation, which was of great help to the ground forces. With the Don crossing secured and Sixth Army's advance flagging on the Volga front, Hitler transferred the Fourth Panzer Army to Army Group B and sent it back to the Volga. The redeployment used enormous amounts of fuel to transfer the army by air and road.


title: Case Blue

text: After crossing the Don on 25 July, Army Group A fanned out on a front from the Sea of Azov to Zymlianskaya (today Zymlyansk). The German Seventeenth Army, along with elements of the Eleventh Army and the Romanian Third Army, manoeuvred west towards the east coast of the Black Sea, while the First Panzer Army attacked to the south-east. The Seventeenth Army made a slow advance but the First Panzer Army had freedom of action. On 29 July the Germans cut the last direct railway between central Russia and the Caucasus, causing considerable panic to Stalin and Stavka, which led to the passing of Order No. 227 "Not a step back!". Salsk was captured on 31 July and Stavropol on 5 August. Although the army group made a quick advance, by 3 August the vanguard comprised only light mobile forces and most of the tanks lagged behind, due to lack of fuel and supply breakdowns, despite the efforts of 4th Air Corps, which flew in supplies around the clock.


title: Case Blue

text: On 9 August, the First Panzer Army reached Maikop in the foothills of the Caucasus mountains, having advanced more than in fewer than two weeks. The western oil fields near Maikop were seized in a commando operation from 8–9 August, but the oil fields had been sufficiently destroyed by the Red Army to take about a year to be repaired. Shortly afterwards Pyatigorsk was taken. On 12 August, Krasnodar was captured and German mountain troops hoisted the Nazi flag on the highest mountain of the Caucasus, Mount Elbrus.


title: Case Blue

text: The length of the German advance created chronic supply difficulties, particularly of petrol; the Black Sea was judged too dangerous and fuel was brought by rail through Rostov or delivered by air, but panzer divisions were sometimes at a standstill for weeks. Even petrol trucks ran out of fuel and oil had to be brought up on camels. With the Soviets often retreating instead of fighting, the number of prisoners fell short of expectations and only 83,000 were taken. As Hitler and OKH began to concentrate on Stalingrad, some of Kleist's mobile forces were diverted. Kleist lost his flak corps and most of the "Luftwaffe" supporting the southern front, only reconnaissance aircraft being left behind. The Voyenno-Vozdushnye Sily (VVS) brought in about 800 bombers, a third of which were operational. With the transfer of air cover and flak units, Soviet bombers were free to harass the German advance. The quality of the Soviet resistance increased, with many of the forces used coming from local levies, who Kleist thought were willing to fight harder for their homeland. German units were especially bogged down by fighting Georgian alpine and mountain troops, who greatly contributed to stalling their advance. The quantity of replacements and supplies the Soviets committed increased, and faced with these difficulties, the Axis advance slowed after 28 August.


title: Case Blue

text: In the south-east, the "Wehrmacht" headed in the direction of Grozny and Baku, the other important petroleum centres. More installations and industrial centres fell into German hands, many intact or only slightly damaged during the Russian retreat. From August–September, the Taman Peninsula and a part of the Novorossiysk naval base were captured. The Germans continued towards Tuapse on the Black Sea coast and in the east Elista was taken on 13 August. In the south, the German advance was stopped north of Grozny, after taking Mozdok on 25 August. German paratroopers assisted an insurgency in Chechnya, operating behind Soviet lines. German mountain troops failed to secure the Black Sea ports and the advance fell short of Grozny as supply difficulties arose once more. The Soviets dug in the 9th and 44th armies of the North Transcaucasian Front along the rocky Terek River bank in front (north) of the city. The "Luftwaffe" was unable to support the German army that far forward and Soviet aviation attacked bridges and supply routes virtually unopposed. The Germans crossed the river on 2 September but made only slow progress. At the beginning of September, Hitler had a major argument with the High Command and specifically List, as he perceived the advance of the German forces as too slow. As a result, Hitler dismissed List on 9 September and took direct command of Army Group A himself.The Germans took Tuapse and got to the peaks.
