Germany is already fighting in the Soviet Union when D-Day happens. Keep that in mind.

In June 1944 the Allies land on the coast of northern France. What does that mean for Germany?

Your verdict

Was America's entry the most important turning point?

The claim

America's entry into the war was the most important turning point of the war.

Place each piece of evidence to load the balance. Mark the strong ones — they count double.

  1. Pearl Harbour (December 1941) brought the USA into the war against both Japan and Nazi Germany.

    Evidence 1: does it support or challenge the claim?
  2. The period 1941-2 weakened Nazi Germany and led to the entry of the USA into the war.

    Evidence 2: does it support or challenge the claim?
  3. The USA later dropped the two atomic bombs on Japan, leading to the end of the war.

    Evidence 3: does it support or challenge the claim?
  4. Another significant turning point was the first defeat of the Nazi army in the Soviet Union.

    Evidence 4: does it support or challenge the claim?
  5. Oak National Academy states that four out of five German soldiers killed in the war died on the Eastern Front.

    Evidence 5: does it support or challenge the claim?
  6. The Battle of Britain had already stopped the invasion of Britain before the USA entered the war.

    Evidence 6: does it support or challenge the claim?

WHAT YOU'VE LEARNED

A quick recap of today's lesson.

Germany ended the war surrounded. Let's find the moments where it all began to turn.

What you need to know

  • A turning point is a moment after which the war's direction changed, and historians interpret which events count.
  • Blitzkrieg (planes, tanks and foot soldiers in one rapid assault) had beaten four nations by 1940.
  • To invade Britain, Germany first had to defeat the RAF. The RAF repulsed the Luftwaffe, and the invasion plans were given up.
  • Have a goYou are planning Germany's seaborne invasion of Britain. What has to happen in the air first?

    The RAF has to be defeated.

    The plan put the air fight first, and because the RAF repulsed the Luftwaffe, the invasion never happened.

  • In June 1941 Hitler invaded the Soviet Union. At first the Nazis took much of its western parts.
  • In December 1941 Japan attacked the USA at Pearl Harbour, so the USA was at war with both Japan and Nazi Germany.
  • Have a goA classmate insists Pearl Harbour was just Japan versus America, so Nazi Germany had nothing to do with it. Who was the USA at war with afterwards?

    Both Japan and Nazi Germany.

    Your classmate has stopped at the attack itself, but it brought the USA into the war against both enemies.

  • In 1942 the Nazis tried to take Stalingrad and were ultimately unsuccessful after five months of fighting.
  • D-Day (June 1944) was the Allied attack on the coast of northern France, so Germany now fought on two fronts.
  • Have a goD-Day put Allied troops in northern France. Where was Germany already fighting, on the other side?

    In the Soviet Union, to the east.

    That fighting had not stopped, which is why the landings meant two fronts, not one.

  • Germany surrendered in May 1945, surrounded by the Allies from the west and Soviet forces from the east.
  • Oak National Academy states that four out of five German soldiers killed in the war died on the Eastern Front.
  • In August 1945 the USA dropped two atomic bombs on Japan, leading to the end of the war.

The big picture

The Second World War turned against Nazi Germany and Japan in stages: the Battle of Britain, then 1941-2 (the invasion of the USSR, Pearl Harbour and Stalingrad), D-Day and the atomic bombs. Which moment mattered most is a matter of interpretation.

Key points

1A turning point is a moment after which the war's direction changed. Ask: what could Germany (or Japan) do before it, and what changed after?
2The Battle of Britain: the RAF repulsed the Luftwaffe, and Germany gave up its plans to invade Britain.
31941-2 weakened Nazi Germany and led to the entry of the USA: the invasion of the USSR (June 1941), Pearl Harbour (December 1941) and Stalingrad (1942).
4D-Day (June 1944) meant Germany was fighting on two fronts, and it hastened Germany's surrender in May 1945.
5Britain and America did not win the war alone: the Soviets pushed the Nazi army back across eastern Europe.
6The two atomic bombs (August 1945) led to the end of the war. Which turning point mattered most is a matter of interpretation.

Worked example

Problem

How long was it from D-Day (June 1944) to Germany's surrender (May 1945)? Then decide what that gap does and does not tell you.

⚠ Watch out

Mixing up which event belongs to which story. Pearl Harbour (December 1941) brought the USA in. D-Day (June 1944) was in northern France. The Soviet Union's fighting was on the Eastern Front. Keep each event in its own place on the timeline.
