Teheran Conference – Roosevelt, Stalin, and Churchill decided upon a meeting in Tehran, Iran from November 28th to December 1st, 1943. The most important achievement of the meeting was agreement on broad plans, especially those for launching Soviet attacks on Germany from the east simultaneously with the prospective Allied assault from the West.
D-Day – Over 3 million Allied troops were prepared in England for the cross-channel invasion of France. The overall command was given to General Eisenhower, and French Normandy, less heavily defended than other parts of Europe, was pinpointed for the invasion assault. On D-Day, June 6, 1944, the enormous operation involving some 4,600 vessels began. Stiff resistance was encountered from the Germans, but the Allies already controlled the air over France and were thus able to block reinforcements by crippling railroads and gasoline-producing plants. An America-French force landed in August 1944 on the southern coast of France and swept northward, allowing the liberation of France in the same month. Allied forces rolled into Germany, and Hitler was doomed.
