qAfter World War I, German admirals were shocked to discover that the Royal Navy had penetrated their secret radio codes and the new, post-war navy set about creating a system so secure that such a breach would never occur again. The result was the now famous Enigma - the Impenetrable Puzzle. This machine was so complex that it was thought no one could break into it; not even when they had a captured machine at their disposal. The German High Command was convinced that the system was wholly secure and totally impregnable.q qTheir supreme confidence was, however, misplaced. During World War Two, Polish cryptanalysts helped Britain to break into the Enigma system used by the Luftwaffe and Army, but the naval version was more complicated. Even so, British cryptanalysts persevered and in the end they did manage the impossible; to break into this most complicated of ciphers. As a result they helped many merchant convoys avoid the teeth of the Wolf Packs.q qThis book describes the story of how the tools for this incredible effort were extracted from the U-boats themselves. With a detailed analysis of the development of Enigma, its role during U-boat operations and the subsequent code-breaking at Bletchley Park, this book will be essential for all those fascinated by this enigmatic tool.q --Book Jacket.As a result they helped many merchant convoys avoid the teeth of the Wolf Packs.aquot; aquot;This book describes the story of how the tools for this incredible effort were extracted from the U-boats themselves.
