Operation Overlord saw some 156,000 Allied troops landing in Normandy on June 6, 1944.
It is thought as many as 4,400 were killed in an operation Winston Churchill described as ‘undoubtedly the most complicated and difficult that has ever taken place’.
The assault was conducted in two phases: an airborne landing of 24,000 British, American, Canadian and Free French airborne troops shortly after midnight, and an amphibious landing of Allied infantry and armoured divisions on the coast of France commencing at 6.30am.
The operation was the largest amphibious invasion in world history, with over 160,000 troops landing. Some 195,700 Allied naval and merchant navy personnel in over 5,000 ships were involved.

The landings took place along a 50-mile stretch of the Normandy coast divided into five sectors: Utah, Omaha, Gold, Juno and Sword.
The assault was chaotic with boats arriving at the wrong point and others getting into difficulties in the water.
Troops managed only to gain a small foothold on the beach – but they built on their initial breakthrough in the coming days and a harbour was opened at Omaha.
They met strong resistance from the German forces who were stationed at strongpoints along the coastline.
Approximately 10,000 allies were injured or killed, inlcuding 6,603 American, of which 2,499 were fatal.
Between 4,000 and 9,000 German troops were killed – and it proved the pivotal moment of the war, in the allied forces’ favour.
