Answers Explained

Q: When did WW2 start?

A: 1 September 1939 — Germany's invasion of Poland.

The war had been building since Hitler's rise to power in 1933. The invasion of Poland was the final trigger. Germany used a new style of rapid warfare — Blitzkrieg (lightning war) — combining tanks, aircraft and infantry that overwhelmed Polish defences in weeks.

Q: What was Operation Overlord?

A: The Allied D-Day landings in Normandy, 6 June 1944.

Operation Overlord was meticulously planned over 18 months. The operation included a massive deception campaign — Operation Fortitude — convincing the Germans the invasion would target Calais rather than Normandy. By late August 1944, Paris was liberated.

Q: Why was the Battle of Stalingrad a turning point?

A: It was the first decisive Axis defeat on the Eastern Front.

Over 800,000 Axis soldiers were killed, wounded or captured at Stalingrad. The German Sixth Army — the most powerful force of the Wehrmacht — was completely destroyed. After Stalingrad, Germany never regained the strategic initiative in the East.

Q: What triggered US entry into WW2?

A: Japan's surprise attack on Pearl Harbor, 7 December 1941.

The attack destroyed or damaged 19 US Navy ships including 8 battleships, and killed 2,403 Americans. Hitler declared war on the United States four days later, bringing the US fully into both the Pacific and European theatres of war.
