In the pre-dawn darkness of April 30, 1943, a body disguised as a Royal Marine Major washed ashore on the coast of Spain, carrying false documents indicating that the Allies were set to launch an attack on Greece, rather than Sicily. Immortalized in the film The Man Who Never Was, Operation Mincemeat is renowned as the most spectacular episode in the annals of deception. In this accurate and in-depth retelling of the story, Denis Smyth draws on a vast collection of previously unavailable documentary sources to provide many key details overlooked in other accounts of Mincemeat. He reveals how the architects of the plan navigated a maze of medical, technical, and logistical issues to deceive the enemy at the highest strategic levels. Before planting the corpse in the Spanish coastal waters via a stealthy submarine operation, the planners not only gave their dead messenger a new military identity, but also a private one--as the fiancé of an attractive young woman named "Pam." Nazi intelligence was fooled, falling for a ruse which ultimately saved thousands of American lives.
