The Normandy Landings, also known as D-Day, took place on June 6, 1944, during World War II. This massive military operation involved Allied forces landing on the beaches of Normandy, France, to begin the liberation of Western Europe from Nazi occupation. Approximately 156,000 troops from the United States, United Kingdom, Canada, and other nations participated in the assault. The operation was one of the largest amphibious invasions in history, featuring extensive planning and coordination. The success of the Normandy Landings marked a significant turning point in the war, leading to the eventual defeat of Nazi Germany and the liberation of occupied territories.
