The double agent's name was Juan Pujol García, also known as Agent Garbo.

He was born in Barcelona, Spain in 1912.

García played a crucial role in the Allied victory in World War II.

He successfully convinced the Germans that the D-Day landings would take place at Calais instead of Normandy.

García was initially turned down by British intelligence but eventually recruited by MI6 in 1942.

He was known for his impressive acting skills and convincing persona as a pro-Nazi spy.

García created a network of fictitious agents that he used to deceive the Germans.

He was awarded both the Iron Cross by the Germans and the Member of the Order of the British Empire by the British.

García faked his own death in order to throw the Germans off his trail.

After the war, García moved to Venezuela where he lived in obscurity until he was rediscovered in the 1980s.
