Before he remade himself as the master spy known as Garbo, Juan Pujol was nothing more than a Barcelona poultry farmer. But as Garbo, he turned in a masterpiece of deception that changed the course of World War II. Posing as the Nazis’ only reliable spy inside England, he created an imaginary million-man army, invented armadas out of thin air, and brought a vast network of fictional subagents to life. The scheme culminated on June 6, 1944, when Garbo convinced the Germans that the Allied forces approaching Normandy were just a feint - the real invasion would come at Calais. Because of his brilliant trickery, the Allies were able to land with much less opposition and eventually push on to Berlin.
