June 6, 1944, known as D-Day, saw the Allies launch a massive beach assault against German forces on the coast of Normandy, France. This operation began the liberation of German-occupied France (and later Western Europe) and laid the foundations of the Allied victory on the Western Front. Planned by a team led by General Eisenhower and involving thousands of troops from the United States, the United Kingdom, Canada, and other Allied nations, D-Day is one of the largest military maneuvers in history. It demonstrated the power of Allied cooperation and marked a turning point in World War II.
