> Joan Clarke, Woman Who Cracked Enigma with Alan Turing Only - Joan and Alan didn't crack Enigma. Worked on it yeah. Made improvements sure. But cracked it

  "Alan Turing ... provided much of the original thinking that led to the design of the cryptanalytical Bombe machines and the eventual breaking of naval Enigma" - Wikipedia Apparently the German army Enigma was cracked because they didn't have rigorous procedures, didn't rotate keys as often as they should. The German Navy had strict discipline and it took Turing et. al. to crack the math before those dispatches could be read.

    Exactly, as has been pointed out above Different use patterns and protocols for Enigma encoding used by different branches of the German military were cracked at different times by different people and teams. The reason Bletchley Park is so famous is for three reasons. One is it cracked the most rigorous and hardest to crack variants of Enigma. Another is that is used forerunners of modern computers to do so and Alan in particular laid some of the theoretical foundations for modern computer systems. Finally it's because cracking the German Navy code basically saved Britain from strangulation by the U-Boat blockade. Yes Poles cracke Enigma first and this provided valuable intelligence, but their explot would not have worked against the Navy variants and would not have made any difference to the Battle of the Atlantic.
