This message was issued by Gen. Dwight D. Eisenhower to encourage Allied soldiers taking part in the D-day invasion of June 6, 1944. Almost immediately after France fell to the Nazis in 1940, the Allies planned a cross-Channel assault on the German occupying forces, ultimately code-named Operation Overlord. By May 1944, 2,876,000 Allied troops were amassed in southern England. The largest armada in history, made up of more than 4,000 American, British, and Canadian ships, lay in wait, and more than 1,200 planes stood ready. Against a tense backdrop of uncertain weather forecasts, disagreements in strategy, and related timing dilemmas, Eisenhower decided before dawn on June 5 to proceed with Overlord.
