"Operation Tiger" was part of a series of large scale D-Day rehearsals. Tragically, coordination and communication problems resulted in friendly fire during the exercise, and an attack by Nazi E-boats resulted in the deaths of 749 American servicemen. The disaster was kept secret due to the impending invasion of Normandy, but now the truth of the tragedy is finally revealed by its survivors.
