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.

Agent Garbo

The Brilliant, Eccentric Secret Agent Who Tricked Hitler and Saved D-Day

Author: Stephan Talty

Page: 304

“The book presses ever forward down a path of historical marvels and astonishing facts. The effect is like a master class that’s accessible to anyone, and Agent Garbo often reads as though it were written in a single, perfect draft.”—The Atlantic Before he remade himself as the master spy known as Garbo, Juan Pujol was nothing more than a Barcelona poultry farmer. But as Garbo, he turned in a masterpiece of deception that changed the course of World War II. Posing as the Nazis’ only reliable spy inside England, he created an imaginary million-man army, invented armadas out of thin air, and brought a vast network of fictional subagents to life. The scheme culminated on June 6, 1944, when Garbo convinced the Germans that the Allied forces approaching Normandy were just a feint—the real invasion would come at Calais. Because of his brilliant trickery, the Allies were able to land with much less opposition and eventually push on to Berlin. As incredible as it sounds, everything in Agent Garbo is true, based on years of archival research and interviews with Pujol’s family. This pulse-pounding thriller set in the shadow world of espionage and deception reveals the shocking reality of spycraft that occurs just below the surface of history. “Stephan Talty’s unsurpassed research brings forth one of the war’s greatest agents in a must-read book for those who think they know all the great World War II stories.” —Gregory Freeman, author of The Forgotten 500

'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.

Battle of Wits

The Complete Story of Codebreaking in World War II

Author: Stephen Budiansky

Publisher: Simon and Schuster

ISBN: 0684859327

Category: History

Page: 436

View: 4685

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.

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?

Alan Turing: The Enigma

The Book That Inspired the Film "The Imitation Game"

Author: Andrew Hodges

Publisher: Princeton University Press

ISBN: 1400865123

Category: Biography & Autobiography

Page: 768

View: 5879

A NEW YORK TIMES BESTSELLER The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades--all before his suicide at age forty-one. This New York Times–bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing's royal pardon in 2013, is the definitive account of an extraordinary mind and life. Capturing both the inner and outer drama of Turing’s life, Andrew Hodges tells how Turing’s revolutionary idea of 1936--the concept of a universal machine--laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program--all for trying to live honestly in a society that defined homosexuality as a crime. The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.

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

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.
