The German military model, the '''[[Wehrmacht]] Enigma''', is the version most commonly discussed.  

The machine has gained notoriety because Allies of World War II cryptologists were able to decrypt a large number of messages that had been enciphered on the machine. Decryption was made possible in 1932 by Polish cryptographers Marian Rejewski, Jerzy Różycki and Henryk Zygalski from Biuro Szyfrów (Cipher Bureau]. In mid-1939 reconstruction and decryption methods were delivered from Poland to United Kingdom and France.  The Military intelligence gained through this source, codenamed [[Ultra|ULTRA]], was a significant aid to the Allied war effort. The exact influence of ULTRA is debated, but a typical assessment is that the Victory in Europe Day was hastened by two years because of the decryption of German ciphers.[http://www.nsa.gov/publications/publi00004.cfm]
