The Second World War
The week runs from the invasion of Poland in 1939 to D-Day in 1944. The lecture argues the Eastern Front decided the war, and the west did not.
Germany attacked on 1 September 1939. Britain and France declared war two days later, so this is where the war in Europe begins.
Most of the German army fought and was destroyed here, from Barbarossa in 1941 to Stalingrad and Kursk in 1943. The lecture treats it as the deciding front.
The Allied landing in Normandy on 6 June 1944 opened a second front, so Germany had to fight east and west at once.
D-Day was not the turning point. Germany was already losing in the east by 1944, and the lecture puts the turning point at Stalingrad.
