When did American troops invade Normandy?

Answer 1

The Normandy Landings were the first operations of the Allied invasion of Normandy, also known as Operation Neptune and Operation Overlord, during World War II. The landings commenced on Tuesday, 6 June 1944 (D-Day), beginning at 6:30 British Double Summer Time (UTC+2). In planning, D-Day was the term used for the day of actual landing, which was dependent on final approval.

The assault was conducted in two phases: an air assault landing of American, British and Canadian airborne troops shortly after midnight, and an amphibious landing of Allied infantry and armoured divisions on the coast of France commencing at 6:30. There were also subsidiary 'attacks' mounted under the codenames Operation Glimmer and Operation Taxable to distract the German forces from the real landing areas.

The operation was the largest single-day amphibious invasion of all time, with 160,000 troops landing on 6 June 1944. 195,700[5] Allied naval and merchant navy personnel in over 5,000 ships were involved. The invasion required the transport of soldiers and materiel from the United Kingdom by troop-laden aircraft and ships, the assault landings, air support, naval interdiction of the English Channel and naval fire-support. The landings took place along a 50-mile (80 km) stretch of the Normandy coast divided into five sectors: Utah, Omaha, Gold, Juno and Sword.
