The Normandy Landings (codenamed Operation Neptune) were the landing operations on Tuesday, 6 June 1944 (termed D-Day) of the Allied invasion of Normandy in Operation Overlord during World War II. The largest seaborne invasion in history, the operation began the liberation of German-occupied northwestern Europe from Nazi control, and contributed to the Allied victory on the Western Front.
The amphibious landings were preceded by extensive aerial and naval bombardment and an airborne assault—the landing of 24,000 American, British, and Canadian airborne troops shortly after midnight. Allied infantry and armoured divisions began landing on the coast of France at 06:30.
When the seaborne units began to land about 06:30 on June 6, the British and Canadians on Gold, Juno, and Sword beaches overcame light opposition. So did the Americans at Utah. The U.S. 1st Division at Omaha Beach, however, confronted the best of the German coast divisions, the 352nd, and was roughly handled by machine gunners as the troops waded ashore. During the morning, the landing at Omaha threatened to fail. Only dedicated local leadership eventually got the troops inland—though at a cost of more than 2,000 casualties.
