Operation Garbo

Juan Pujol Garcia, better known as Garbo, was perhaps the most influential spy of World War II. By feeding false information to the Germans on the eve of the D-Day landings he ensured their absence in great numbers from Normandy’s beaches. This allowed the Allied push against Hitler to begin. Amazingly, Garbo’s cover was never broken.
After the war Juan Pujol Garcia faked his own death and moved to Venezuela where he opened a book store. He died in Caracas in 1988.
