During the war there was a great premium on secure communications. The British had broken the Germans Code and of course the United States had been reading the Japanese secure communications since before the war. So the Army tried to find a secure manner of communicating.
Most people know of the work of the Navajos in the Pacific as portrayed in the movie "Windtalker's" which depicted their heroic exploits. But very few people know of the secret work of the Woman's Army Corp (WAC's) who were involved in their own top secret operation.
The Army was of course a very misogynistic place during World War Two so when women began to wear the uniform they were ignored and patronized by most of the officer corps. Except for one man. Brigadier General Theodore Roosevelt Jr. knew of the strange ability that some woman had to force air through their vagina's. When he was involved in the planning for D-Day he brought it to the attention of General Eisenhower. Together with OSS spymaster Allen Dulles they trained a series of young woman who could communicate a series of signals in code by forcing air through their naughty bits. This was particularly useful in large meetings that were attended by dubious characters such as the Free French under Giruad and the Soviet Union's representative General Potemkin. The WAC's often served as secretaries or drivers and when they saw a particular note or aside they would communicate by queefing in code. Then General Eisenhower's driver Kay Summersby would write down the message and pass it to her boss so he was in the know without anyone else suspecting.
