This thesis traces the efforts in the 1930s of the Polish, French, and British Intelligence Services to break the German Enigma ciphering machine, efforts which led to the Bletchley Park Ultra operations of World War II. The cooperation, and lack thereof, among the Intelligence Services is discussed, with the conclusion that more cooperation sooner would have better served the individual national interests of each.
