U.S. troops wade ashore during the Allied invasion of Normandy, France, June 6, 1944.
D-Day was one of the world’s most gut-wrenching and consequential battles. Nearly 160,000 American, British, Canadian and French troops participated in the invasion of northwest France, known as Operation Overlord. More than 9,000 Allied forces were killed or wounded.
The Allied landing led to the liberation of France, and marked the turning point in the European theater of World War II.
