The breaking of the Enigma Codes in WWII was one of the defining actions of the whole war. Many books have been written about this as one of the best kept secrets of WW2. Few have looked right inside the Enigma cipher machine itself...Inside Enigma does just that. It brings to life how the Enigma machines were used, how the messages were encoded and why the Enigma code was virtually unbreakable.

Enigma expert Professor Tom Perera, W1TP, provides a history of these fascinating machines from their predecessors through to the cipher machines of the Cold War. The wartime Enigmas used by the German Army and Navy are covered in great depth, as well as the development of coding machines, into the post-war variants. Includes a guide to finding and buying your very own Enigma machine and instructions for building a modern day one.
