The Chicken Farmer Who Defeated Hitler
"Juan Poyol, the Spanish chicken farmer, the most important moment in World War II was D-Day. So as D-Day was happening, Juan gave so much fake information, he convinced them that D-Day was going to happen in Calais. So Hitler and Himmler were getting these reports from Juan. They thought the war was going to happen in Calais, so they sent some of their most important armies, to Calais, then the D-Day happens."
Juan Poyol, a failed chicken farmer, was rejected by MI5 multiple times before joining the Nazis to become valuable enough for British intelligence to recruit him. He became the only person to receive both Hitler's Iron Cross and an MBE from the King, convincing the Nazis that D-Day would occur at Calais instead of Normandy, causing Hitler to redeploy critical forces. He faked his own death in 1949 and lived secretly in Venezuela until the 1980s when former MI5 agents discovered he was still alive.

About this episode

The podcast episode features a detailed historical account of Juan Poyol, a Spanish chicken farmer who became one of World War II's most valuable double agents. After being repeatedly rejected by the British Embassy in Madrid in 1941, Poyol took the extraordinary step of joining Nazi intelligence to make himself valuable enough for MI5 to recruit. Once accepted by both sides, he created an elaborate network of 27 fictional sub-agents that fed false intelligence to the Nazis throughout the war. His most significant contribution came during D-Day, when his disinformation convinced Hitler and Himmler that the Allied invasion would occur at Calais rather than Normandy, causing German forces to be fatally misdeployed. MI5 codenamed him Garbo after actress Greta Garbo due to his exceptional acting skills. Poyol became the only person in history to receive both the Iron Cross from Hitler and an MBE from the British King. The episode reveals that he faked his own death to malaria in Mozambique in 1949 and lived secretly in a Venezuelan bookstore until the 1980s, when former MI5 agents discovered he was still alive. The discussion explores themes of agency, persistence, and strategic thinking, noting that Poyol is considered one of the three most important figures of D-Day alongside Eisenhower and Montgomery. The episode also touches on post-war Nazi threats and why Poyol felt compelled to remain in hiding for decades despite the war's end.
