D-Day in Pictures
Almost immediately after France fell to the Nazis in 1940, the Allies planned a cross-Channel assault on the German occupying forces. At the Quebec Conference in August 1943, Winston Churchill and Franklin Roosevelt reaffirmed the plan, which was code-named Overlord. Although Churchill acceded begrudgingly to the operation, historians note that the British still harbored persistent doubts about whether Overlord would succeed.

The decision to mount the invasion was cemented at the Teheran Conference held in November and December 1943. Joseph Stalin, on his first trip outside the Soviet Union since 1912, pressed Roosevelt and Churchill for details about the plan, particularly the identity of the Supreme Commander of Overlord. Churchill and Roosevelt told Stalin that the invasion would be possible by August 1, 1944, but that no decision had yet been made to name a Supreme Commander. To this latter point, Stalin pointedly rejoined, "Then nothing will come of these operations. Who carries the moral and technical responsibility for this operation? Churchill and Roosevelt acknowledged the need to name the commander without further delay.
