“An absorbing and thoroughly well documented account” of WWII naval intelligence and the Allied hunt for the Nazi code machine known as the Enigma (Warship). From the start of World War II to mid-1943, British and American naval forces fought a desperate battle against German submarine wolfpacks. And the Allies might have lost the struggle at sea without an astounding intelligence coup. Here, the author brings to life the race to break the German U-boat codes. As the Battle of the Atlantic raged, Hitler’s U-boats reigned. To combat the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of Hitler’s cipher device, the Enigma. They first found success with the capture of U-110,—which yielded the Enigma machine itself and a trove of secret documents. Then the weather ship Lauenburg seized near the Arctic ice pack provided code settings for an entire month. Finally, two sailors rescued a German weather cipher that enabled the team at Bletchley to solve the Enigma after a year-long blackout. In “a highly recommended account with a wealth of materials” Seizing the Enigma tells the story of a determined corps of people who helped turn the tide of the war (Naval Historical Foundation).

The Atlantic in World War II is the setting for the race to break the German U-boat codes and turn the tides of war by the losing British and American navys.

For almost sixty years after their deaths, three men, whose brave actions shortened the Second World War by as much as two years, remained virtually unknown and uncelebrated. Two lost their lives retrieving vital German codebooks from a sinking U-boat. The third survived the war, only to die in a house fire soon afterwards. But it was the precious documents they seized in October 1942 that enabled Bletchley Park's code-breakers to crack Enigma and so win the Battle of the Atlantic. Now recognised as a pivotal moment in world history, three British servicemen made it possible to finally beat the U-boats, but at the time not even their families could be told of the importance of their deeds. Shrouded in secrecy for decades, then recast as fictional Americans by the Hollywood film U-571, this book sets the record straight. It is written in celebration of Colin Grazier GC, Tony Fasson GC, and Tommy Brown GM - the REAL Enigma heroes.

The first full account of Hitler's extensive intelligence network-and the dramatic story of how Germany lost the battle of the secret services in World War II.

Spies, secret messages, and military intelligence have fascinated readers for centuries but never more than today, when terrorists threaten America and society depends so heavily on communications. Much of what was known about communications intelligence came first from David Kahn's pathbreaking book, The Codebreakers. Kahn, considered the dean of intelligence historians, is also the author of Hitler’s Spies: German Military Intelligence in World War II and Seizing the Enigma: The Race to Break the German U-Boat Codes, 1939-1943, among other books and articles. Kahn’s latest book, How I Discovered World War II's Greatest Spy and Other Stories of Intelligence and Code, provides insights into the dark realm of intelligence and code that will fascinate cryptologists, intelligence personnel, and the millions interested in military history, espionage, and global affairs. It opens with Kahn telling how he discovered the identity of the man who sold key information about Germany’s Enigma machine during World War II that enabled Polish and then British codebreakers to read secret messages. Next Kahn addresses the question often asked about Pearl Harbor: since we were breaking Japan’s codes, did President Roosevelt know that Japan was going to attack and let it happen to bring a reluctant nation into the war? Kahn looks into why Nazi Germany’s totalitarian intelligence was so poor, offers a theory of intelligence, explicates what Clausewitz said about intelligence, tells—on the basis of an interview with a head of Soviet codebreaking—something about Soviet Comint in the Cold War, and reveals how the Allies suppressed the second greatest secret of WWII. Providing an inside look into the efforts to gather and exploit intelligence during the past century, this book presents powerful ideas that can help guide present and future intelligence efforts. Though stories of WWII spying and codebreaking may seem worlds apart from social media security, computer viruses, and Internet surveillance, this book offers timeless lessons that may help today’s leaders avoid making the same mistakes that have helped bring at least one global power to its knees. The book includes a Foreword written by Bruce Schneier.
