During World War II, Hitler's Nazi soldiers often contracted sexually transmitted diseases, especially syphilis, from the French prostitutes they frequented. This is why Hitler approved the top-secret "Borghild Project," in 1940, a mission inspired by SS chief Heinrich Himmler, who first alerted Hitler to the syphilis problem.

The dolls were inflatable, blonde, blue-eyed, and could fit into the soldier's backpacks. Unfortunately, the soldiers soon refused to carry the dolls for fear that the dolls would be discovered if they were ever captured by enemy forces.
