Actually I gather it had a lot to do with the fact that
the Germans made some blunders in the way they used the
Enigma that seriously compromised its security. There
was reportedly a branch of the German forces that used
their Enigmas differently, avoiding those mistakes, and
the British never managed to crack any of their messages.
