1944 May, During the Allied invasion of Anzio the Germans broke secret codes and "murdered" the allied forces. Military security began to use an electromechanical machine known as Sigaba, whose codes were never broken.
SIGABA - Wikipedia, the free encyclopedia
SIGABA was similar to the Enigma in basic theory, in that it used a series of rotors to encipher every character of the plaintext into a different character of ciphertext. Unlike Enigma's three rotors however, the SIGABA included fifteen, and did not use a reflecting rotor.
By 1943, more than 10,000 SIGABA machines were in use.
