Summary: During the night of 27th April 1944, Exercise Tiger, a rehearsal for the D-day landings, took place off the coast of Devon. This supposedly routine exercise experienced a series of fatal blunders that allowed German E boats to intercept the convoy of landing craft. By dawn, nearly 1000 American servicemen, many young and untrained, had lost their lives. This story explains how and why the tragedy happened, and explores the elaborate cover-up that later took place. It is also the tale of one man's obsession to honour the memory of those Americans who died so needlessly.
