If memory serves me correctly the Poles did a clandestine op in Germany where they stole either a prototype or an early Enigma machine to study. Later Polish cryptanalysts\mathematicians at the fall of Poland escaped to France then later to the UK. The heroes of cracking Enigma are three Polish mathematicians not Alan Turing! Turing’s contribution was in the computing machine used and contributed to early Computer Science design & theory. He’s played up by the UK because he’s British and because it’s fashionable to promote him because he’s was homosexual.
Post #80 was meant to be directed to you. That was an excellent example of how history gets warped and those who actually deserve credit too often get the short end.
