Operation Fortitude: The Story Of The Spies And The Spy Operation That Saved D-Day

Operation Fortitude tells the thrilling tale of an ingenious deception that changed the course of the Second World War. The story is one of intrigue, drama, and good fortune, practically a Hollywood script. It is the tale of double agents, fake radio transmissions and dummy invasion craft.

The success of D-Day was made possible by the efforts of people who were not even present on the Normandy Beaches. General Patton spent D-Day on British shores commanding a phantom army. Spanish double-agent GARBO sent messages relaying supposed intelligence from his fictitious spy network, fooling the Nazis right up until the end of the war. Even as the Normandy landings were happening, Hitler remained convinced they were a diversionary tactic to force him to move his troops. So, thanks to Fortitude, D-Day was a triumph; without it the war might well have had a very different outcome.
