Nazi Germany and Axis partners open the Eastern Front by invading the Soviet Union along a vast front, aiming for a rapid destruction of Soviet forces and seizure of key cities and resources.
Major fighting erupts around Smolensk as German panzer groups attempt deep encirclements on the road to Moscow; Soviet resistance slows the advance and contributes to the failure of a quick campaign.
German and Finnish forces isolate Leningrad, initiating a prolonged blockade that becomes one of the deadliest sieges in modern history and ties down major forces on the northern sector of the front.
Following the German capture of Kyiv, Nazi killing units carry out mass shootings at Babi Yar (29–30 September 1941), illustrating the integration of genocidal violence with the eastern campaign.
Germany launches its main drive on Moscow; the ensuing campaign culminates in Soviet defense and counteroffensives that halt the Wehrmacht and shatter expectations of a swift victory in the USSR.
Axis forces besiege the major Soviet naval base at Sevastopol, beginning a long struggle for control of Crimea and the Black Sea approaches.
After months of bombardment and assaults, Sevastopol falls to Axis forces, marking a major (if costly) German success in the southern theater before the 1942 push toward the Volga and Caucasus.
The Red Army launches a major counteroffensive north and south of Stalingrad, smashing weaker Axis allied formations and trapping the German Sixth Army—an operational turning point on the Eastern Front.
After the encirclement and protracted fighting, remaining Axis forces in Stalingrad capitulate, delivering Germany a catastrophic defeat and shifting strategic initiative to the USSR.
German forces under Manstein counterattack overextended Soviet formations after Stalingrad, recapturing Kharkov and temporarily stabilizing the front before the decisive summer battles of 1943.
Germany launches a major offensive against the Kursk salient; Soviet defenses and subsequent counteroffensives defeat the attack, ending Germany’s ability to regain the strategic offensive in the east.
Soviet operations break the blockade and restore land communications to Leningrad, concluding the 872-day siege and marking a major strategic and moral victory for the USSR.
The Red Army opens its massive summer offensive in Belarus, shattering German Army Group Centre and driving the front far west—one of Germany’s greatest military disasters.
