Subtitled The True Spy Story that Changed the Course of World War II, Operation Mincemeat is about the Allies’ deception plan codenamed Operation Mincemeat in 1943, which underpinned the invasion of Sicily. It was framed around a man who never was.

The success of the Sicilian invasion depended on overwhelming strength, logistics, secrecy and surprise. But it also relied on a wide web of deception, and one deceit in particular: a spectacular con trick dreamed up by a team of spies led by an English lawyer. (page xi)

At first I found this book a little confusing and far too detailed, but as I read on I became absolutely fascinated and amazed at what had actually happened. The plan was to take a dead body, equipped with false documents, deposit it on a beach in Spain, so that it would be passed over to the Germans and divert them from the real target into believing that the preparations to invade Sicily were a bluff.

Operation Mincemeat would feed them both a false real plan, and a false cover plan – which would actually be the real plan (page 58)

The corpse was a Welsh tramp who had committed suicide. His body was clothed in the uniform of an Royal Marine with documents identifying him as Major William Martin and letters about the top-secret Allied invasion plans. This involved creating a fictional character, a whole host of imaginary agents and sub-agents all with their own characteristics and imaginary lives – just as in a novel. The details of the deception were dreamt up by Ewan Montagu, a barrister and Charles Cholmondeley (pronounced Chumley), a flight-lieutenant in the RAF seconded to MI5, the Security Service. Both were enthusiastic readers, which stood them in good stead:

For the task of the spy is not so very different from that of the novellist: to create an imaginary credible world, and then to lure others into it, by words and artifice. (page 62)

The plan was not without its faults and and indeed it contained some potentially fatal flaws, but incredibly it succeeded.

Operation Mincemeat was pure make-believe; and it made Hitler believe something that changed the course of history. (page 307)

This is a book, totally outside my usual range of reading. I wasn’t expecting to enjoy it as much as I did and I think I did enjoy it because it was so far-fetched to be almost like reading a fictional spy story. I marvelled at the ingenuity of the minds of the plans’ originators and the daring it took to carry it out.
