Great Mysteries and Myths of the Twentieth Century (1998)

Season 1: Episode 14

D-Day was the largest amphibious operation ever mounted in the history of world conflict. It not only transported hundreds of thousands of men and their equipment onto the beaches of Normandy, but also supplied their fuel, stores and supplies on a logistical basis never previously seen. Hitler was completely taken by surprise - the result of several major deceptions involving dummy armies, mythical bomber squadrons and the "secret plans" supposedly discovered in a briefcase.
