I agree. Amazingly, it was the Poles who came up with some of the initial breaks in Enigma.

Have you ever visited the NSA's web site? There are some interesting (and long) articles about Enigma and how it was broken. Click on this link:

Warning: Reading "The Cryptographic Mathematics of Enigma" will make you insane or your head explode!

I haven't seen the NSA article, but have read Codebreakers - a good read.

IMHO the Poles have never gotten enough credit for getting their hands on the first machine.

I got to see an original Enigma in the Imperial War Museum, a way cool place.
