THE SECOND WORLD WAR 1939-45


THE SECOND WORLD WAR 1939-45



9.1 Wartime Alliances

May 1939 Pact of Steel required both countries to help each other in war.



Britain would not ally with the USSR because:

  • Feared Communism
  • Knew about mass murder
  • Believed that the Red army was useless because of purges



Stalin believed he was on his own and signed a 10-year Non-aggression Pact with Hitler.

Also called Nazi-Soviet Pact or Molotov-Ribbentrop Pact, it had secret clauses that allowed Germany to take ½ of Poland and the USSR to have the rest and the Baltic States.

After Barbarossa the alliance with Britain and France happened.



The US sided with Britain and France because:

  • Concern about Nazism
  • Ethnic ties
  • Big business would lose if Hitler took over Europe

1940 Roosevelt started the ‘Lend-lease Programme’ that would loan arms to Britain while the war lasted.

December 1941 Pearl Harbour the US declared war.



The Allies = Britain, France, USA and USSR

The Axis = Germany, Italy and Japan.





9.2 A Run of German Victories

1st September 1939 invasion of Poland.

Blitzkrieg destroyed Poland in 2 weeks.

By the end of October Poland was divided.

Blitzkrieg tactics

The Phoney War


Winter 1939-40. No fighting

France felt safe behind the Maginot line.

Germany stayed behind the Siegfried Line.

Britain sent the BEF.



In April Hitler took control of Norway, Sweden and Denmark.

Quisling became head of a puppet government in Norway.

In May the Netherlands, Luxembourg and Belgium surrendered



The Fall of France


In June Churchill, who had just become PM, had to evacuate the BEF from Dunkirk.

Petain became  leader of the Vichy government.

Mussolini, who sensed a German victory, declared war.



Dunkirk Evacuation

Britain Alone


Operation Sea Lion.

Goring’s Luftwaffe V Air Marshall Hugh Dowding’s RAF

The Battle of Britain July 1940 to June 1941

The Blitz.





9.3 The Soviet State at War

November 1939 the USSR invaded Finland. They made such hard work out of it that Hitler was convinced an invasion of USSR would be easy.



Operation Barbarossa


June 1941 3 million men in a 3 pronged attack on Leningrad, Moscow and the Caucasian oilfields.

500,000 died in a900 day siege of Leningrad. Still the Russians held out until help came.

General Zhukov and ‘General Winter’ pushed the Germans back in Moscow.

General Von Paulus 6th army sent to Stalingrad.

Zhukov defended at all costs. Hitler wouldn’t let Von Paulus surrender. He had to in the end.

The German army started to retreat.

Russian victory in tank battle at Kursk.



Reasons for Soviet Victory


  • Hitler delayed Barbarossa for 2 months in order to help Mussolini in Greece.
  • General Winter
  • Russians dismantled factories and moved them east.
  • Nazi brutality galvanised Russians
  • Soviet scorched-earth policy





9.4 Allied Victory

American build-up

Montgomery’s victory over Rommel at El Alamein and Eisenhower’s trapping of the enemy at Tunis meant the way was clear to attack Germany through Italy.

Mussolini deposed but set up as a puppet ruler.

Germans defended Italy fiercely.



Operation Overlord


German ‘Atlantic Wall’

Eisenhower in charge of D-day, 6th June 1944.

Omaha, Utah, Gold, Juno and Sword

General Patton landed in the South of France and linked with the Normandy troops.

Eisenhower and Montgomery quarrelled but Eisenhower’s more cautious approach prevailed.

General Von Runstedt lost the Battle of the Bulge. Last chance over.

April 1945 Hitler committed suicide on the same day the Russians entered Berlin.

8th May VE day


Normandy Landings

Japan Surrenders

After Pearl Harbour, Japan continued its conquest of Asia.

1942 the Battle of the Coral Sea sank the ‘Lexington’(aircraft carrier)

Battle of Midway defeated the Japanese Fleet (kamakazi)

Japan’s refusal to surrender in the battles for islands led to the use of atomic bombs.

Hiroshima and Nagasaki

Attack on Pearl Harbour

Dropping Atomic Bomb

The Grand Alliance


This refers to the fact that the allied leaders were prepared to sink their differences until Hitler was defeated.

They met at wartime conferences:

  1. 1943 Tehran Conference. Stalin, Churchill and Roosevelt agreed that a second front be opened in France. A replacement for the League of Nations should be set up.
  2. February 1945 Yalta. They advanced a charter for the UN but failed to agree on the future of Poland.
  3. 1945 (after the war) Potsdam decided on division of Germany but already cracks were appearing





9.5 The Technology of War



Infantry


Lighter, faster-firing rifles developed. British Lee Enfield. German Karabiner.

The mortar became the soldiers’ own light artillery.



Tanks


Very prominent role.

US Sherman V Panzer

El Alamein and Kursk

Allied Tanks

German Tanks of WW2


Rockets


V1 and V2 defeated when the launching sites were bombed.



Planes


Most important.

British Hurricanes and Spitfires (pilot’s favourite) V Messerschmidt

Stuka dive bomber used in Blitzkrieg

German big bombers Heinkel and Junker

British Lancaster and Wellington

US Flying Fortress

Use of radar important



Code

Thousands employed at Bletchley Park to crack Enigma.

Success led directly to the defeat of Rommel in North Africa.

Imitation Game: Movie about Enigma


Allied Bombing


Luftwaffe no real threat after the Battle of Britain.

Sir Arthur Harris (bomber) started with ‘surgical strikes’ but RAF losses were high.

Then adopted ‘carpet bombing’ of German cities (Dresden, Cologne, Berlin)

Ended the war quicker. Morality?



The Atomic Bomb


1942 a team of British and US scientists embarked on the ‘Manhattan Project’

Harry Truman approved the Enola Gay.

Nagasaki and Hiroshima. Led to quick surrender.



The Sea


Germany relied on small battleships and U-Boats.
U Boats

The Schnorkel tube made U-Boats very effective until escorted convoys, the centrimetric radar, and  the Hedgehog depth charge were introduced.

The US and the Japanese made great use of aircraft carriers but US established dominence at the Battle of Midway.

Everyday in WW2


Fallen of WW2

Winston Churchill

We Shall fight on the beaches
