Operation Garbo

Garbo was the British codename of Juan Pujol Garcia, perhaps the most influential spy of the Second World War. By feeding false information to the Germans on the eve of the D-Day landings he ensured Hitler held troops back that might otherwise have defeated the Normandy landings. This allowed the Allied push against the Nazis in Europe to begin. Amazingly, Garbo's cover was never broken and he remains the only person ever to have been awarded both the British MBE and the German Iron Cross. After the war Garbo faked his own death and fled to Venezuela with a mistress, where he later opened a book store. Ironically, his family in Spain only found out he was still alive when this book was published - Garbo having failed to realise it would also be translated into Spanish.
