The Great Patriotic War, 1941-1945
For four years from June 1941 the Soviet Union fought the largest land war in history. Roughly 27 million Soviet citizens died — about one in seven. By 1945 Stalin was master of half of Europe and a co-architect of the post-war world. The story of the Great Patriotic War is one of catastrophic early losses, brutal endurance, and a transformation of Stalin’s rule that combined wartime relaxation with renewed terror after victory.
The Nazi-Soviet Pact, 1939
In August 1939, Stalin and Hitler stunned the world by signing the Nazi-Soviet Pact, a non-aggression treaty negotiated by Foreign Minister Vyacheslav Molotov and his German counterpart Joachim von Ribbentrop. Secret protocols divided Eastern Europe into spheres of influence: Stalin took eastern Poland, the Baltic states and parts of Romania; Hitler took western Poland and a free hand against the West. Stalin saw the Pact as buying time and pushing the Soviet border westwards. Hitler always intended to break it.
Operation Barbarossa, June 1941
Stalin received dozens of warnings of an imminent German attack — from British intelligence, his own spies (Richard Sorge in Tokyo, Leopold Trepper’s Red Orchestra), and his front-line generals. He dismissed them as British provocations. On 22 June 1941, three million German and Axis soldiers crossed the Soviet frontier in Operation Barbarossa. The Luftwaffe destroyed most of the Soviet air force on the ground in 24 hours.
Stalin reportedly withdrew to his dacha for several days, possibly expecting to be arrested by his own Politburo. When he eventually addressed the nation by radio on 3 July, he called Soviet citizens ‘brothers and sisters’ — family language not used in Stalin propaganda before. By December 1941 the Germans had reached the suburbs of Moscow. Three million Soviet soldiers had been killed or captured.
Operation Barbarossa launched on 22 June 1941 with three million Axis troops. Stalin had ignored intelligence warnings and the 1937 purges had stripped the army of experienced commanders. By December 1941, three million Soviet soldiers had been killed or captured, and the Germans were at the gates of Moscow.
Mobilising the Home Front
The most dramatic Soviet achievement was industrial. Between July and December 1941, around 1,500 factories were dismantled and shipped east of the Ural Mountains, beyond the reach of German bombers. Workers, mostly women, restarted production on muddy ground in the Urals winter. By 1942, Soviet weapons output exceeded German output. The T-34 tank — faster, better-armoured and easier to produce than its German rivals — became the iconic Soviet weapon of the war.
Female employment surged again. Women drove tractors, ran lathes, served as pilots in the ‘Night Witches’ bomber regiment, and worked as front-line snipers and medics. Around half a million women served in the Red Army. American Lend-Lease — trucks, food, aviation fuel, raw materials — helped: the USSR received over 400,000 trucks and roughly 14,000 aircraft. The relative weight of Lend-Lease versus Soviet production is debated; both mattered.
Leningrad, Stalingrad and Kursk
The siege of Leningrad ran from September 1941 to January 1944 — 872 days. Roughly one million civilians died, mostly of starvation; people ate wallpaper paste, leather and, in extreme cases, the dead. The Battle of Stalingrad, between August 1942 and February 1943, became the war’s turning point. German Sixth Army, encircled by a Soviet pincer movement (Operation Uranus, November 1942), surrendered on 2 February 1943 under Field Marshal Friedrich Paulus — 91,000 prisoners of whom only 5,000 survived to return home in the 1950s.
The Battle of Kursk in July 1943, the largest tank engagement in history, confirmed Soviet superiority. From there, Soviet forces drove west, reaching Berlin in April 1945. Germany surrendered to the Red Army in Berlin late on 8 May 1945; in Moscow it was already 9 May — Victory Day, still Russia’s most important national holiday.
Stalin’s record as a wartime leader is contested. Early failures — ignoring intelligence, paralysis at Barbarossa, ordering ‘not one step back’ (Order 227 of July 1942) which forbade retreat at Stalingrad on pain of death — cost millions of Soviet lives. Later, he learned to delegate to professionals like Marshal Georgy Zhukov, the most successful Red Army commander, who oversaw victories at Moscow, Stalingrad, Kursk and Berlin. Stalin chaired the State Defence Committee that ran the war effort and made the strategic decisions on factory evacuation. Never write that Stalin was always brilliant — weigh the early failures against the eventual victory.
Wartime Society
War transformed daily life. Stalin tactically relaxed pressure on the Russian Orthodox Church — reopening churches, releasing imprisoned bishops — to mobilise patriotic feeling. Wartime propaganda emphasised Russian rather than Communist heroes (Alexander Nevsky, Suvorov) and used the term ‘Motherland’ (Rodina) more than ‘socialism’. The Comintern was dissolved in 1943 to reassure the Western Allies. Conditions for ordinary Soviets remained brutal: rationing, conscription, deportation of suspect minorities (Chechens, Crimean Tatars, Volga Germans) en masse. Famines hit again in 1942-43.
Repression continued alongside this relaxation. Order 270 in 1941 declared every Soviet soldier who surrendered to the enemy a traitor; their families could be punished. SMERSH (military counter-intelligence, set up in 1943) shot deserters and screened returning prisoners of war. The gulag continued to expand. Wartime relaxation was tactical, not principled — once victory was secured, much of it would be reversed.
From 1941 onwards Stalin deported entire ethnic groups suspected of disloyalty. Volga Germans were uprooted in 1941 within weeks of Barbarossa. Chechens and Ingush were deported from the North Caucasus in February 1944 — around half a million people moved by cattle truck to Kazakhstan and Central Asia in days, with thousands dying of cold and hunger en route. The Crimean Tatars followed in May 1944, accused of collaborating with the German occupiers; nearly a third died in the first year of exile. The deportations show the wartime regime continuing the pre-war logic of collective punishment, even as it relaxed pressure on the Orthodox Church for tactical reasons.
The Cost of Victory
By 1945 the USSR had paid a price beyond comparison. Roughly 27 million Soviet dead, perhaps two-thirds of them civilians. About 1,700 cities and 70,000 villages were destroyed. Industry had to be rebuilt from rubble across European Russia, Ukraine and Belarus. Yet the Soviet Union emerged a superpower — with the Red Army occupying Eastern Europe, atomic-weapon research underway, and a permanent seat on the UN Security Council. Stalin was at the height of his international authority. Within a year of victory the wartime alliance with Britain and the United States had collapsed into the Cold War.
The Soviet Union lost roughly 27 million people in the war — about one in seven citizens. The siege of Leningrad lasted 872 days; the German Sixth Army surrendered at Stalingrad on 2 February 1943. The cost was matched by transformation: the USSR emerged a superpower controlling Eastern Europe.
