How did Adolf Hitler react to the D-Day invasion of Normandy on 6 June 1944, when American, British, and Canadian troops established a foothold in western Europe? He slept through it, having convinced his Nazi cohorts that the rumored Allied attack would be a diversion designed to fool the Nazis into deploying considerable military assets in the wrong place.
At the Berghof, Hitler's Bavarian Alps residence, the Führer and his entourage stayed up late, watching the latest newsreels and celebrating until 3 a.m., according to Nazi associate Joseph Goebbels. By 6 a.m. the widespread attack was confirmed, but the Führer's aides were hesitant to wake him. “The news couldn’t be better,” Hitler reportedly said upon awakening about 10 a.m.
