The D-Day invasion of Normandy on 6 June 1944 was a massive undertaking involving approximately 6,939 Allied ships, 11,590 aircraft and 156,000 troops.
The military term "D-day" refers to the day when a combat operation is to begin, and "H-hour" is the exact time the operation is to begin. This concept allows military strategists to plan an operation in advance, even when the exact date and time of action are still unknown.
D-Day, however, would be associated with the invasion of Normandy, one of the largest and most famous amphibious campaigns in the history of the war. As D-Day fades further away in the mirror of history, photos remain with us, almost a no-compromise for that extraordinary, remarkable event.
