Velites

Velites (singular: ) were a class of infantry in the Roman army of the mid-Republic from 211 to 107 BC. "Velites" were light infantry and skirmishers who were armed with a number of darts (), each with a 30-inch wooden shaft the diameter of a finger, with a 10-inch (25 cm) narrow metal point, to fling at the enemy. They also carried short thrusting swords, or "gladii", for use in melee. They rarely wore armour as they were the youngest and poorest soldiers in the legion and could not afford much equipment. They did carry small wooden shields called "parma" for protection, and wore headdresses made from wolf skins so their brave deeds could be recognized. The "velites" were placed at the front partly for tactical reasons, and also so that they had the opportunity to secure glory for themselves in single combat.
"Velites" did not form their own units; a number of them were attached to each "maniple" of "hastati", "principes" and "triarii". They were typically used as a screening force, driving off enemy skirmishers and disrupting enemy formations with javelin throws before retiring behind the lines to allow the heavier-armed "hastati" to attack. They were normally the ones who engaged war elephants and chariots if they were present on the field, such as in the Battle of Zama, in 202 BC. Their high mobility and ranged weaponry made them much more effective against these enemies than heavy infantry. An early Roman legion contained approximately 1,000 "velites". "Velites" were eventually disbanded after the Marian reforms. Lucilius suggests that "rorarii" and "velites" were interchangeable, with "velites" gradually superseding "rorarii". Another theory is that the "leves"' equipment was upgraded until they were at the same level as the "rorarii", and they both collectively became known as the "velites".
Equipment.
"Velites" were the youngest and usually the poorest (being fifth class citizens, with property worth 400–2,500 "denarii") soldiers in the legion, and could rarely afford much equipment. They were armed with "veretum", light javelins, each with a 90 cm (3 ft) wooden shaft the diameter of a finger, with a 10-inch (25 cm) narrow metal point, and tips designed to bend on impact to prevent them being thrown back, similar to the heavier "pila" of other legionaries. Livy says that they each carried seven javelins, however Roman satirist Lucilius says that they carried five, suggesting that the amount may have changed. The "hastati" and "principes" carried "gladii", relatively short thrusting swords 74 centimetres (29 inches) in length, as their main weapons, and the "velites" carried them as backup weapons. They fought in a very loose, staggered formation like most irregular troops, and carried small round shields called "parma", 90 cm (3 feet) in diameter.
The "velites" were placed at the front of the "maniples", so that the "velites" had the chance to prove themselves and win glory by seeking out single combat with an enemy. This is also why they wore highly identifiable wolfskin headdresses.
Organization.
In the legion, the "velites" were attached to each maniple of "hastati", "principes" and "triarii". They usually formed up at the front of the legion before battle to harass the enemy with javelin throws and to prevent the enemy doing the same before retiring behind the lines to allow the heavier infantry to attack. After they had fallen back, they would move up behind the attacking troops and throw darts at the enemy. They also sometimes carried wounded back to the rear, however usually a corps of "deportates" did this. In a pitched battle, the "velites" would form up at the front of the legion and cover the advance of the hastati, who were armed with swords. If the "hastati" failed to break the enemy, they would fall back and let the "principes", similarly equipped though more experienced infantry, take over. If the "principes" failed, they would retire behind the "triarii", well trained, heavily armoured, spear armed legionaries and let them attack.
The number of "triarii" was fixed at 600 per legion, there were usually 1,200 "hastati" and 1,200 "principes" per legion, with the rest being light infantry like the "velites". In the standard legion around the time of the Second Punic War (218 -201 BC) there were 10 "maniples" of "hastati", each having 120 "hastati", with 40 "velites" attached. The "maniples" were further split into centuries, of 60 "hastati" and 20 "velites", with the centurion of the "hastati" century commanding the "velites" as well.
After the Romans were ambushed at the Battle of Lake Trasimene, which remains the largest ambush in military history by men involved, in 217 BC, Quintus Fabius Maximus Verrucosus introduced a military step known as the "agmen". It was a variable formation, with one or more columns, separated by cohorts, with their allies in between the cohorts. The front of the columns were the "extraordinarii", along with some of the "velites". Following this formation was a rear-guard of the "ablecti", and the rest of the "velites". The baggage trail was guarded by the cavalry. Both the front and the flanks contained a number of "speculatores" (scouts), to provide warning of an enemy army's approach. When enemies were nearby, the baggage train would be dispersed between the "maniples". If the columns were forced to retreat, the "velites" and the "extraordinarii" that were in the front guarded the retreat of the others; this contrasts with their usual method of retreat, in which the cavalry, the "velites", and the "triarii" stayed behind and covered the retreat.
When the Romans set up a temporary "castra", two "maniples" (without their "velites") were selected to pitch the tents of the headquarters and officers, and details were made for fatigue duty, to get wood and water, and to give food and water to the animals accompanying them. The rest of the men, excepting "velites" and officers, set up the tents of the soldiers. During this time the "velites" would guard the outside of the wall and the wall itself, while the rest of the troops would guard the interior. The watch, which was composed of eight men led by a decurion, ran from 6:00 am to 6:00 pm, and was divided into four shifts, each of three hours.
History.
"Velites" were descended from an earlier class of light infantry, "leves", dating from the Camillan legion of the 5th century BC, who had a very similar role to the "velites". They were also the poorer and younger soldiers in the legion, though the "rorarii" and "accensi" classes were considerably poorer and were eventually disbanded, having insufficient equipment to be effective soldiers. Leves were likewise armed with a number of javelins, but carried a spear rather than a sword. Like the "velites", "leves" did not have their own units, but were attached to units of "hastati".
Lucilius, however, suggests that "rorarii" and "velites" were interchangeable, with "velites" gradually superseding "rorarii". Another theory is that the "leves"' equipment was upgraded until they were at the same level as the "rorarii", and they both collectively became known as the "velites".
"Velites" were first used, and created, at the siege of Capua in 211 BC, and were made up of citizens who would normally be too poor to join the "hastati" but were called up due a shortage of manpower. They were trained to ride on horseback with the "equites" and jump down at a given signal to fling javelins at the enemy. After the siege, they were adopted into the legions as a force of irregular light infantry for ambushing and harassing the enemy with javelins before the battle began in earnest.
The "velites" were used against the Carthaginian elephants in the Battle of Zama. After their usual javelin throw, the "velites" took cover behind the "maniples", and then launched a sortie, quickly coming out from behind the troops and attacking the elephants, before retreating again.
With the military reforms of Gaius Marius in 107 BC, designed to combat a shortage of manpower due to wars against Jugurtha, the different classes of units were disbanded entirely. The wealth and age requirements were scrapped. Now soldiers would join as a career, rather than as service to the city, and would all be equipped as heavy infantry with the same, state purchased equipment.
The Imperial Guard of Napoleon were named after the Roman "velites".
