context_page_description: The Eastern Front of World War II was a theatre of conflict between the European Axis powers and co-belligerent Finland against the Soviet Union, Poland and other Allies, which encompassed Central Europe, Eastern Europe, Northeast Europe, and Southeast Europe from 22 June 1941 to 9 May 1945. It is known as the Great Patriotic War in the Soviet Union and some of its successor states, while everywhere else it was called the Eastern Front.
  The battles on the Eastern Front of the Second World War constituted the largest military confrontation in history. They were characterised by unprecedented ferocity, wholesale destruction, mass deportations, and immense loss of life due to combat, starvation, exposure, disease, and massacres. Of the estimated 70–85 million deaths attributed to World War II, around 30 million occurred on the Eastern Front. The Eastern Front was decisive in determining the outcome in the European theatre of operations in World War II, eventually serving as the main reason for the defeat of Nazi Germany and the Axis nations.
  The two principal belligerent powers were Germany and the Soviet Union, along with their respective allies.
context_section_description: Operation Barbarossa began just before dawn on 22 June 1941. The Germans cut the wire network in all Soviet western military districts to undermine the Red Army's communications. Panicky transmissions from the Soviet front-line units to their command headquarters were picked up like this: "We are being fired upon. What shall we do?" The answer was just as confusing: "You must be insane. And why is your signal not in code?"
  At 03:15 on 22 June 1941, 99 of 190 German divisions, including fourteen panzer divisions and ten motorised, were deployed against the Soviet Union from the Baltic to the Black Sea. They were accompanied by ten Romanian divisions, three Italian divisions, two Slovakian divisions and nine Romanian and four Hungarian brigades. On the same day, the Baltic, Western and Kiev Special military districts were renamed the Northwestern, Western and Southwestern Fronts respectively.
  To establish air supremacy, the Luftwaffe began immediate attacks on Soviet airfields, destroying much of the forward-deployed Soviet Air Force airfield fleets consisting of largely obsolescent types before their pilots had a chance to leave the ground. For a month the offensive conducted on three axes was completely unstoppable as the panzer forces encircled hundreds of thousands of Soviet troops in huge pockets that were then reduced by slower-moving infantry armies while the panzers continued the offensive, following the Blitzkrieg doctrine.
  Army Group North's objective was Leningrad via the Baltic states. Comprising the 16th and 18th Armies and the 4th Panzer Group, this formation advanced through the Baltic states, and the Russian Pskov and Novgorod regions. Local insurgents seized the moment and controlled most of Lithuania, northern Latvia and southern Estonia prior to the arrival of the German forces.
  Army Group Centre's two panzer groups (the 2nd and 3rd), advanced to the north and south of Brest-Litovsk and converged east of Minsk, followed by the 2nd, 4th, and 9th Armies. The combined panzer force reached the Beresina River in just six days, 650 km (400 mi) from their start lines. The next objective was to cross the Dnieper river, which was accomplished by 11 July. Their next target was Smolensk, which fell on 16 July, but the fierce Soviet resistance in the Smolensk area and slowing of the Wehrmacht advance by the North and South Army Groups forced Hitler to halt a central thrust at Moscow and to divert the 3rd Panzer Group north. Critically, Guderian's 2nd Panzer Group was ordered to move south in a giant pincer manoeuvre with Army Group South which was advancing into Ukraine. Army Group Centre's infantry divisions were left relatively unsupported by armour to continue their slow advance to Moscow.
  This decision caused a severe leadership crisis. The German field commanders argued for an immediate offensive towards Moscow, but Hitler over-ruled them, citing the importance of Ukrainian agricultural, mining and industrial resources, as well as the massing of Soviet reserves in the Gomel area between Army Group Centre's southern flank and the bogged-down Army Group South's northern flank. This decision, Hitler's "summer pause", is believed to have had a severe impact on the Battle of Moscow's outcome, by slowing down the advance on Moscow in favour of encircling large numbers of Soviet troops around Kiev.
  Army Group South, with the 1st Panzer Group, the 6th, 11th and 17th Armies, was tasked with advancing through Galicia and into Ukraine. Their progress, however, was rather slow, and they took heavy casualties in a major tank battle. At the beginning of July, the Third and Fourth Romanian Armies, aided by elements of the German 11th Army, fought their way through Bessarabia towards Odessa. The 1st Panzer Group turned away from Kiev for the moment, advancing into the Dnieper bend (western Dnipropetrovsk Oblast). When it joined up with the southern elements of Army Group South at Uman, the Group captured about 100,000 Soviet prisoners in a huge encirclement. Advancing armoured divisions of the Army Group South met with Guderia
