The impact of the war on the soviet union

When did the USSR join WW2

when nazi germany invaded the soviet union in June 1941 - this broke the terms of the nazi soviet pact

the Grand Alliance?

Stalin’s response to the growing fascist threat was to form the “Grand Alliance” with USA and Britain

It formed after Operation Barbarossa in June 1941, when Nazi Germany invaded the USSR.

Despite deep ideological hatred between capitalism and communism, they united to defeat Adolf Hitler.

👉 It was an alliance of necessity, not trust.

Operation Barbarossa

22 June 1941 Nazi Germany launched operation Barbarossa and made rapid gains into soviet territory

October 1941 another army was marching on Moscow and by December over 6m red army soldiers and many towns,cities and villages were overrun, this early success was down to Stalin’s mistaken belief that the Nazi-soviet pact would safeguard the USSR

Foreign aid

The USSR benefited from foreign aid from the USA and Great Britain munitions,transport and raw materials

300,000 trucks

• 14,000 aircraft

• 13,000 tanks

what was stalin’s reaction to the nazi germany invasion of june 1941

On 22 June:

• Stalin did not immediately address the nation.

• Foreign Minister Vyacheslav Molotov announced the invasion instead.

This is significant — it suggests hesitation, shock, or uncertainty.

new position

By 30 June:

• He became head of the State Defence Committee (GKO) — effectively dictator of the war effort.

• He later took the title of Supreme Commander.

This centralised all military, economic and political authority in his hands.

So while his initial reaction may have involved shock, institutionally he moved quickly to take total control.

the speech

On 3 July, Stalin finally addressed the Soviet people by radio.

This speech is hugely important.

He:

• Called citizens “brothers and sisters”

• Framed the war as a patriotic struggle

This marks the beginning of the Great Patriotic War narrative.

phase one

• 22 June 1941: Operation Barbarossa Begins.

• 30 June 1941: Creation of the GKO.

• 3 July 1941: Stalin’s First Radio Address.

• 16 August 1941: Order 270. Stalin issues a decree stating that commanders and commissars who surrender or retreat are traitors; their families would be liable to arrest.

• 8 September 1941: Siege of Leningrad Begins. German forces encircle the city. The siege would last for nearly 900 days, resulting in over 600,000 civilian deaths from hunger and cold.

• 19 September 1941: Fall of Kiev. A catastrophic defeat where approximately 665,000 Soviet troops are captured after Stalin refuses to allow a retreat.

• 5–6 December 1941: Soviet Counter-Offensive at Moscow. Aided by the Russian winter and fresh troops from Siberia, the Red Army halts the German advance and pushes them back, marking the failure of the German Blitzkrieg.

• July 1942: Fall of Rostov. The city falls to the Germans with little resistance, marking one of the lowest points of the war for the Soviet Union.

phase two turning the tide

• (1942 – Summer 1943)

  
  

• 28 July 1942: Order 227. Known as "Not a Step Back!", this order is issued to stiffen resistance after the fall of Rostov. It demands that troops defend every meter of Soviet territory.

• 19 November 1942: Operation Uranus. The Soviet counter-offensive at Stalingrad begins, eventually encircling the German Sixth Army.

• 2 February 1943: German Surrender at Stalingrad. The German Sixth Army surrenders. This is a psychological and military turning point, proving the USSR could defeat the Wehrmacht.

• July 1943: Battle of Kursk. The Germans launch Operation Citadel. It results in the largest tank battle in history (Prokhorovka). The Red Army, utilizing T-34 tanks, halts the offensive, seizing the strategic initiative for the remainder of the war.

• 9 May 1945: Victory Day. Germany surrenders. By the war's end, the USSR has emerged as a military-industrial superpower, though at the cost of approximately 20 million Soviet lives.

The Kiev disaster

• The Kiev Disaster (Sept 1941): When General Zhukov advised a strategic withdrawal from Kiev to save the army, Stalin refused and poured in reserves. The result was the encirclement and capture of approximately 665,000 Soviet troops—a catastrophe caused directly by Stalin’s refusal to listen to military experts.

reliance on civil war tactics

• Inflexible "Stand Fast" Strategy: Stalin relied on tactics from the Russian Civil War (1918–21), demanding fierce discipline and constant offense. This "no retreat" policy was disastrous against the Nazi Blitzkrieg, which used encirclement. Stalin denied commanders flexibility, micromanaging army movements from Moscow.

order 227 not a step back

• Order 227 "Not a Step Back" ( 28 July 1942): Issued after the humiliating fall of Rostov, this order created "blocking detachments" to shoot "panic-mongers." While brutal, it was a desperate measure to stiffen resistance before the shift to better strategic planning took effect.

strategic at kursk

• Strategic Patience (Kursk, 1943): When facing the German buildup at Kursk, Stalin wanted to launch a pre-emptive offensive (his old habit). Zhukov advised a "defense in depth" strategy to absorb the German attack first. The "new Stalin" accepted this advice, leading to the decisive victory at Prokhorovka.

turning the tide

• Professionalizing the Command: Stalin appointed Zhukov as Deputy Supreme Commander and promoted talented officers like Vasilevsky (Chief of Staff) and Antonov. He began to accept a "collegiate" style where disagreement was tolerated, allowing the experts to plan.

• Reducing Political Interference: In the autumn of 1942, at Stalin's insistence, the powers of the politruki (political commissars) were reduced. Commanders were no longer automatically executed for failure, fostering greater self-reliance and initiative.

road to victory

• The Race for Berlin (1945): Stalin’s paranoia and political ambition returned. Fearing the Western Allies might reach Berlin first, or that his own generals might steal the glory, he pitted Marshal Zhukov against Marshal Konev in a race to capture the city. This rushed frontal assault resulted in exceptionally severe and unnecessary loss of life.

• Diplomatic Skill: At the Tehran (1943) and Yalta (1945) conferences, Stalin proved to be a skilled diplomat. He exploited divisions between Churchill and Roosevelt to secure a Soviet sphere of influence in Eastern Europe, achieving his long-term security aims.

industrial decline

Coal - 1940 165.9m/t 1945 - 149.3m/t

Electricity - 48.3 m KWH- 43.2m KWH

Oil 31.1 m/t - 19.4m/t

devastating impact on the economy

factory

By the end of 1941 1523 factories had been moved incl. 100+ aircraft factories up to 1.5m railway wagon Stalin moved them eastward

the red army was producing aircraft,tanks ,guns and shells faster than the germans 1942-1945

This helped the USSR maintain production.

• Tank production massively increased

• Around 80,000 T-34 tanks produced

Industrial mobilisation meant the USSR could replace massive losses.

agriculture output

agriculture suffered and by 1943 output was 38% of 1940 but peasants remained resilient , manage to feed towns and cities under horrific conditions

Stalin responsibility for initial losses

• error of judgement as Stalin believed that the Germans would not attack the USSR until they defeated Britain

• He ignored eighty warnings of German intentions

• In the week before the nazi invasion, Stalin refused the requests of the red army commanders to have their at battle readiness and in better defensive positions

• June 1941 the Russians had hardly any heavy guns,radio equipment, or minefields Stalin also underestimated the scale of the nazi invasion

Stalin’s ruthlessness

he was able to send millions to their deaths in battle

Order 270 - 16 august 1941 “commanders and commisars who leave the front or surrender will be considered deserters and their families liable to arrest”

over 430,000 men served in punishment companies

Crimean tatars

May 1944.

Deportation of the Crimean Tatars

What happened

• Soviet secret police (NKVD) surrounded Crimean Tatar villages.

• Families were given minutes to pack belongings.

• They were forced onto cattle trains and transported east.

Around 190,000–200,000 Crimean Tatars deported.

Stalin’s wartime regime remained brutally repressive despite the patriotic unity of the war effort.

splitting the German advance

1941

Hitler made a critical decision in August 1941 to divide German forces instead of focusing on Moscow.

Army groups:

• Army Group North → Leningrad

• Army Group Centre → Moscow

• Army Group South → Ukraine

Hitler temporarily diverted Army Group Centre south to Kiev.

Consequences:

• delayed the attack on Moscow by several months

• gave the USSR time to reinforce the capital

This contributed to German failure at the Battle of Moscow (winter 1941).

Russian winter

Germany was not prepared for the Russian winter.

Key facts:

• temperatures dropped to –30°C or lower

• German troops lacked winter uniforms

• tanks and vehicles froze

Supply problems were severe because:

• German supply lines stretched over 1,000 km

• Soviet railways used different track gauges, slowing logistics

Consequences:

• German offensives stalled

• Soviet counteroffensives pushed them back from Moscow.

operation URANUS

november 1942

• about 300,000 Axis troops trapped

• 91,000 captured

• only about 5,000 ever returned to Germany

This was the first major German defeat of the war.

Kursk

Germany attempted one last major offensive at the Battle of Kursk (July 1943).

Facts:

• largest tank battle in history

• about 6,000 tanks involved

Problems for Germany:

• the attack was delayed several months

• this allowed the Soviets to build deep defensive lines

The USSR deployed:

• around 1.3 million soldiers

• 3,600 tanks

Germany failed to break through.

Consequences:

• Germany permanently lost the strategic initiative on the Eastern Front.
