Title: The Polish perspective on Enigma
Review: This book tells the story of the Polish breaking of the German Enigma code before WWII and thru the early part of the war. The famous English Enigma work was based on the earlier work performed by 3 Polish mathematicians. This book tells how the Polish broke the code using mathematics (not a captured machine as is commonly thought) and details the methods used to decrypt messages when settings were changed. There is a lot of (Polish) patriotic pride in this book which occasionally gets in the way of the content, but it is an excellent book nonetheless. It includes an appendix in which the mathematician who originally broke Enigma explains exactly how he did it which is especially interesting.
