On 22 June 1941, Nazi Germany invaded the Soviet Union across a 2,900-kilometer front, initiating Operation Barbarossa. Adolf Hitler committed over 3.8 million German and allied troops to destroy the Red Army, capture vital agrarian and industrial regions, and eradicate the Soviet state. The Axis force advanced in three principal thrusts: Army Group North aimed through the Baltic states for Leningrad, Army Group Center drove through Belarus toward Moscow, and Army Group South attacked through Western Ukraine toward Kiev and the Donbas.
Surprise was pervasive. Frontline Red Army communications dissolved under airstrikes and artillery bombardments, allowing German panzer groups to execute massive double envelopments. North of the Pripyat Marshes, Panzer Groups 2 and 3 trapped large Soviet concentrations around Bialystok and Minsk, capturing several hundred thousand Soviet soldiers within weeks. In the northwest, Army Group North drove across the Dvina and Luga rivers toward Leningrad. In the south, resistance proved firmer around Brody and Rovno, but Army Group South progressively forced Soviet formations into retreat across Ukraine.
In July, Army Group Center enveloped Smolensk, pocketing multiple Soviet field armies and approaching the Moscow axis. However, bitter Soviet counterattacks and logistical strain delayed the drive. Hitler redirected Panzer Group 2 southward to coordinate with Army Group South in an encirclement east of Kiev. By September 1941, the resulting pocket captured four Soviet field armies and secured Ukraine, while Army Group North severed the land approaches to Leningrad, commencing an extended siege.
On 30 September 1941, Germany initiated Operation Typhoon, resuming the offensive toward Moscow. German panzers surrounded large Red Army forces at Vyazma and Bryansk, capturing hundreds of thousands more Soviet troops. Autumn rains turned the dirt roads to impassable mud, slowing the Axis supply columns to a crawl. When freezing temperatures arrived, the mechanized spearheads pressed toward the northern and southern suburbs of Moscow. Severely depleted, lacking winter clothing, and overextended across hundreds of kilometers of hostile terrain, the German armies met newly assembled Red Army reserves under General Georgy Zhukov. On 5 December 1941, the German advance ground to an absolute halt, marking the strategic defeat of the initial blitzkrieg campaign.
