Britain planned to end the war by turning Hitler into a woman, a new book reveals.
The Allies schemed to smuggle female sex hormone, estrogen, into Hitler’s food in an attempt to make him less aggressive.
The female hormone plot was one of a number of bizarre ideas to end the war, according to a new book by academic Brian Ford.
Estrogen was chosen for its tasteless properties, Ford claims, and because it would have a slow and subtle effect, making it easier to smuggle past Hitler's food testers.
Ford said: “There was an allied plan that they would smuggle oestrogen into Hitler’s food and change his sex so he would become more feminine and less aggressive.
“Their research had showed the importance of sex hormones – they were beginning to be used in sex therapy in London.
“The plan was to give sex hormones to Hitler and counterbalance his unnecessary aggression.
“There were agents who would be able to get it into his food – it would have been entirely possible.
“He had testers who used to taste his food. There was no mileage to putting poison in his food because they would immediately fall victim to it.
“Sex hormones were a different matter. They only affected you if you took them for weeks or months on end, so no one would have ever realised that the hormones were in the food.”
Other strange plots included dropping glue on Nazi troops in an attempt to stick them to the ground and disguising bombs in tins of fruit being imported to Germany.
Ford’s book, Secret Weapons: Technology, Science And The Race To Win World War II, published by Osprey, will be launched on September 20.
