What were Operation Overlord, Operation Neptune and the Battle of Normandy? When did they take place?
The armed forces use codenames to refer to the planning and execution of specific military operations. Operation Overlord was the codename for the Allied invasion of north-west Europe. The assault phase of Operation Overlord was known as Operation Neptune. This operation involved landing the troops on the beaches, and all other associated supporting operations required to establish a beachhead in France. Operation Neptune began on D-Day (6 June 1944) and ended on 30 June 1944. By this time, the Allies had established a firm foothold in Normandy. Operation Overlord also began on D-Day, and continued until Allied forces crossed the River Seine on 19 August 1944. The Battle of Normandy is the name given to the fighting in Normandy between D-Day and the end of August 1944.
