On the morning of June 5, 1944, U.S. General Dwight D. Eisenhower gave the go-ahead for Operation Overlord, the largest amphibious military operation in history. On his orders, 6,000 landing craft, ships and other vessels carrying 176,000 troops began to leave England for the trip to France. That night, 822 aircraft filled with parachutists headed for drop zones in Normandy. An additional 13,000 aircraft were mobilized to provide air cover and support for the invasion. By dawn on June 6, 18,000 parachutists were already on the ground; the land invasions began at 6:30 a.m. The British and Canadians overcame light opposition to capture Gold, Juno and Sword beaches; so did the Americans at Utah. The task was much tougher at Omaha beach, however, where 2,000 troops were lost and it was only through the tenacity and quick-wittedness of troops on the ground that the objective was achieved. This amphibious operation became the turning point for World War II in Europe. This famous battle is called D-Day or the Invasion of Normandy.
