Battle of Wits

The Complete Story of Codebreaking in World War II
Author: Stephen Budiansky
Publisher: Simon and Schuster

A million pages of new World War II codebreaking records have been released by the U.S. Army and Navy and the British government over the last five years. Now, Battle of Wits presents the history of the war that these documents reveal. From the Battle of Midway until the last German code was broken in January 1945, this is an astonishing epic of a war that was won not simply by brute strength but also by reading the enemy's intentions. The revelations of Stephen Budiansky's dramatic history include how Britain tried to manipulate the American codebreakers and monopolize German Enigma code communications; the first detailed published explanations of how the Japanese codes were broken; and how the American codebreaking machines worked to crack the Japanese, the German, and even the Russian diplomatic codes. This is the story of the Allied codebreakers puzzling through the most difficult codebreaking problems that ever existed. At the same time, the compelling narrative shows the crucial effect codebreaking had on the battle-fields by explaining the urgency of stopping the wolf pack U-boat attacks in the North Atlantic, the burning desire in the United States to turn the tide of the war after Pearl Harbor, the importance of halting Rommel's tanks in North Africa, and the necessity of ensuring that the Germans believed the Allies' audacious deception and cover plans for D-Day. Budiansky brings to life the unsung code-breaking heroes of this secret war: Joseph J. Rochefort, an intense and driven naval officer who ran the codebreaking operation in "The Dungeon", a dank basement at Pearl Harbor, that effectively won the Battle of Midway; Alan Turing, the eccentric father of the computerage, whose brilliant electromechanical calculators broke the German Enigma machine; and Ian Fleming, whose daredevil espionage schemes to recover codebooks resembled the plots of the 007 novels he later wrote. Among the villains, we meet the Nazi Admiral Donitz, who led the submarine wolf packs against Allied shipping in the North Atlantic with horrific casualty rates -- until the codebreakers stopped him. Budiansky, a Harvard-trained mathematician, demonstrates the mathematical insight and creativity of the cryptographers by showing step-by-step precisely how the codes were broken. This technology -- the flow of information, its encryption, and the computational methods of recovering it from the enemy -- had never before been so important to the outcome of a war. Informative diagrams, maps, appendices, and photographs show exactly how, why, and where the secret war was won. Unveiled for the first time, the complete story of codebreaking in World War II has now been told.

Bletchley Park's Architect of Ultra Intelligence

A magnificent biography which finally provides recognition to one of Bletchley's and Britain's lost heroes.' Michael Smith??The Official Secrets Act and the passing of time have prevented the Bletchley Park story from being told by many of its key participants. Here at last is a book which allows some of them to speak for the first time. Gordon Welchman was one of the Park's most important figures. Like Turing, his pioneering work was fundamental to the success of Bletchley Park and helped pave the way for the birth of the digital age. Yet, his story is largely unknown to many. His book, The Hut Six Story, was the first to reveal not only how they broke the codes, but how it was done on an industrial scale. Its publication created such a stir in GCHQ and the NSA that Welchman was forbidden to discuss the book or his wartime work with the media.??In order to finally set the record straight, Bletchley Park historian and tour guide Joel Greenberg has drawn on Welchman's personal papers and correspondence with wartime colleagues which lay undisturbed in his son's loft for many years. Packed with fascinating new insights, including Welchman's thoughts on key Bletchley figures and the development of the Bombe machine, this is essential reading for anyone interested in the clandestine activities at Bletchley Park.??As seen in the Kent and Sussex Courier, Dover Express, Folkestone Herald, Sevenoaks Chronicle, M.K.

Without warning, a Starfleet ship is overwhelmed by a mysterious, alien aggressor -- one who appears to possess an intimate knowledge of the vessel's tactical technology. Then a second Starfleet ship is attacked. And a third. Twenty-eight-year-old Jean-Luc Picard, captain of the U.S.S. Stargazer -- a Constellation-class starship -- is ordered to help form a desperate line of defense against the aggressor. But it seems nothing can stop the aliens' headlong plunge into the heart of the Federation. Or rather, nothing in front of them can. Trailing one of the alien attack formations is a tiny Starfleet shuttle with a half dozen crewmembers aboard. One of them is Picard's first officer and best friend, Gilaad Ben Zoma. Another is Arlen McAteer, the ambitious admiral who has made it his business to relieve Picard of his command. Can Ben Zoma and McAteer work together to unlock the secret of the alien assault? Or will their differences sabotage their effort -- and deprive the Federation of its last hope for survival?

'Briggs is an engaging and amiable guide though the mysteries of wartime cryptography . . . a fascinating account of an outstanding young man and his time at a quite remarkable institution.' Roger Moorhouse in BBC History magazine Lord Briggs has long been regarded as one of Britain's most important historians. However, until the publication of this remarkable book, he had never written about his time at Bletchley Park. Briggs himself did not tell his wife about his wartime career until the 1970s and his parents died without ever knowing about their son's contribution to the war effort. In this meticulously researched account he finally reveals the details of his life in Hut Six working as a code breaker alongside Alan Turing and Gordon Welchman. In addition to discussing the progress of the Allies' code breaking efforts and its impact on the war, Lord Briggs considers what the Germans knew about Bletchley and how they reacted to revelatory memoirs about the Enigma machine, which were not published until the 1970s. Packed with fascinating anecdotes, this is the gripping, revelatory story of an extraordinary young man in an extraordinary place.

The breaking of the Enigma machine is one of the most heroic stories of World War II, and highlights the crucial work of the Bletchley Park codebreakers which shortened the war by several years. But there was another code machine used by Hitler himself to convey messages to his top commanders in the field. More complex and secure than Enigma, it could never be broken. For 60 years no one knew about Lorenz or "Tunny," or the courageous group of men who finally broke the code. Here for the first time, codebreaker Jerry Roberts tells how these forgotten heroes of Bletchley broke Hitler's top secret code, and how he finally got the codebreakers the recognition they deserve.

Ultra -- the code word for the greatest secret of World War II -- was the method by which the Allies intercepted German radio transmissions and broke their coded contents. But how was this information transmitted to the battlefield? Author Ronald Lewin was the first historian to utilize actual Ultra intercepts to show how this information was used in combat. He is also the first historian to have interviewed the men, both British and American, who produced and used Ultra intercepts in the key positions of leadership throughout the war. In documenting these incredible events, author Ronald Lewin tells the story of Ultra from 1920 through 1945. He utilized more than 70,000 previously secret Ultra intercepts. He has interviewed the Head of the Polish secret service who provided the Allies with the first Ultra code-breaking equipment before WWII started. He shows how the German radio signals were intercepted, how the codes were broken, how the information was evaluated, how Allied reactions were planned, and what impact this Ultra material had on the field of battle

View: 9374
The original history of Bletchley Park's Hut 6 was considered so sensitive, it was only declassified in June 2006. For the first time the wider public can read the story of Bletchley Park's epic battle with the Enigma-enciphered messages of the German Army and Air Force, as written by the codebreakers and edited by John Jackson. This momentous struggle is told anonymously by the men and women working in Hut 6 at Bletchley Park, who recorded their experiences in a top secret report at the end of World War 2. Where the German forces went the Enigma machine went with them. The daily changing cipher keys and the continuous security improvements put a continual strain on the quiet heroes of Bletchley Park. This specially edited version of the original three volumes, which includes all of the volume on cryptography, is a lasting tribute to their unrelenting pursuit of the innermost secrets of the Nazi war machine and to their genius in overcoming all the odds.
