This was to be 'Station X', the Allies' top-secret centre for deciphering enemy codes.Their task was to break the ingenious Enigma cypher used for German high-level communications. The settings for the Enigma machine changed continually and each day the German operators had 159 million million million different possibilities. Yet against all the odds this gifted group achieved the impossible, coping with even greater difficulties to break Shark, the U-Boat Enigma, and Fish, the cypher system used by Hitler to talk to his generals.'Sation X' is also the story of the people involved from leading codebreakers such as Alan Turing, father of the modern computer, to the female operators who intercepted the messages. Through interviews with surviving members of Bletchley Park, Michael Smith has discovered what life was like there. In this chaotic and isolated environment they found time for drama performances, music recitals, orchestras and love affairs.Not only did these people shorten the war by several years - they were essential to victory in the Atlantic and North Africa and to the masterminding of the D-Day landings - 'Station X' was also the birth place of the world's first programmable computer and the successful Anglo-American intelligence partnership.

    He was twenty-two. Soon recognized as a cryptographer of genius, he became head of communications at the Special Operations Executive (SOE), where he revolutionized the codemaking techniques of the Allies and trained some of the most famous agents dropped into occupied Europe, including "the White Rabbit" and Violette Szabo. As a top codemaker, Marks had a unique perspective on one of the most fascinating and, until now, little-known aspects of the Second World War. Writing with the narrative flair and vivid characterization of his famous screenplays, Marks gives free rein to his keen sense of the absurd and his wry wit, resulting in a thrilling and poignant memoir that celebrates individual courage and endeavor, without losing sight of the human cost and horror of war.

    This country house was home to Britain's most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology—indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the scientists and the codebreaking, fictional and non-fiction—from Robert Harris and Ian McEwan to Andrew Hodges' biography of Turing—what of the thousands of men and women who lived and worked there during the war? The first history for the general reader of life at Bletchley Park, this is also an amazing compendium of memories from people now in their eighties of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in), of a youthful Roy Jenkins—useless at codebreaking, of the high jinks at nearby accommodation hostels, and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other's work.

    Sebag-Montefiore also relates new details about the genesis of the code, little-known facts about how the Poles first cracked the Luftwaffe's version of the code (and then passed it along to the British), and the feverish activities at Bletchley Park. Based in part on documents recently unearthed from American and British archives--including previously confidential government files--and in part on unforgettable, firsthand accounts of surviving witnesses, Enigma unearths the stunning truth about the brilliant piece of decryption that changed history.

    This book rewrites the history of computer science, arguing that in reality Colossus--the giant computer built by the British secret service during World War II--predates ENIAC by two years.Colossus was built during the Second World War at the Government Code and Cypher School at Bletchley Park. Until very recently, much about the Colossus machine was shrouded in secrecy, largely because the code-breaking algorithms that were employed during World War II remained in use by the British security services until a short time ago. In addition, the United States has recently declassified a considerable volume of wartime documents relating to Colossus. Jack Copeland has brought together memoirs of veterans of Bletchley Park--the top-secret headquarters of Britain's secret service--and others who draw on the wealth of declassified information to illuminate the crucial role Colossus played during World War II. Included here are pieces by the former WRENS who actually worked the machine, the scientist who pioneered the use of vacuum tubes in data processing, and leading authorities on code-breaking and computer science.A must read for anyone curious about code-breaking or World War II espionage, Colossus offers a fascinating insider's account of the world first giant computer, the great great grandfather of the massive computers used today by the CIA and the National Security Agency.

    The guerrilla campaign that followed was every bit as extraordinary as the six men who directed it. One of them, Cecil Clarke, was a maverick engineer who had spent the 1930s inventing futuristic caravans. Now, his talents were put to more devious use: he built the dirty bomb used to assassinate Hitler's favorite, Reinhard Heydrich. Another, William Fairbairn, was a portly pensioner with an unusual passion: he was the world's leading expert in silent killing, hired to train the guerrillas being parachuted behind enemy lines. Led by dapper Scotsman Colin Gubbins, these men—along with three others—formed a secret inner circle that, aided by a group of formidable ladies, single-handedly changed the course Second World War: a cohort hand-picked by Winston Churchill, whom he called his Ministry of Ungentlemanly Warfare.Giles Milton's Churchill's Ministry of Ungentlemanly Warfare is a gripping and vivid narrative of adventure and derring-do that is also, perhaps, the last great untold story of the Second World War.

    Almost to the end of the war, the Germans had firm faith in the Enigma ciphering machine, but in fact the codebreakers were deciphering nearly 4,000 German transmissions daily by 1942, reaping a wealth of information on such important matters as the effort to resupply Rommel's army in North Africa and the effect of Allied attempts to mislead the Germans about the location of D-Day landings. Indeed, Winston Churchill hailed the work of Bletchley Park as the secret weapon that won the war. Only now, nearly half a century since the end of the Second World War, have any of the men and women in this group come forward to tell this remarkable story in their own words--a story that an oath of secrecy long prevented them from revealing. In Codebreakers, F.H. Hinsley and Alan Stripp have gathered together twenty-seven first-hand accounts of one of the most amazing feats in intelligence history. These engaging memoirs, each written by a different member of the codebreakers team, recount the long hours working in total secrecy and the feelings of camaraderie, tension, excitement, and frustration as these men and women, both British and American, did some of the most important work of the war. These talented people share not only their technical knowledge of cryptography and military logistics, but also poignant personal recollections as well. Walter Eytan, one of a handful of Jews at Betchley Park, recalls intercepting a message from a German vessel which reported that it carried Jews en route for Piraeus zur Endlosung (for the final solution). Eytan writes I had never heard this expression before, but instinctively, I knew what it must mean, and I have never forgotten that moment. Vivienne Alford tells of her chilling memory of hearing that the atomic bomb had been dropped on Hiroshima, and the stillness that came over her and her co-workers in Naval Section VI. And William Millward confides that he is still haunted by the work he did in Hut 3 nearly fifty years ago. I sometimes wonder, especially during the night, how many sailors I drowned. Few readers will finish this book without feeling that the codebreakers were essential to the outcome of the war--and thereby of major importance in helping to shape the world we live in today.

    Purpose? To deceive the Nazis into thinking the Allies were planning to attack Europe by way of Greece or Sardinia, rather than Sicily, as the Nazis had assumed & the Allies ultimately chose. Charles Cholmondeley of MI5 & the British naval intelligence officer Ewen Montagu were very different. Cholmondeley was a dreamer seeking adventure. Montagu was an aristocratic, detail-oriented barrister. A perfect team, they created an ingenious plan: equip a corpse with secret (but false) papers concerning the invasion, then drop it off the coast of Spain where German spies would hopefully take the bait. The idea was approved by British intelligence officials, including Ian Fleming (007's creator). Winston Churchill believed it might ring true to the Axis & help bring victory.Filled with spies, double agents, rogues, heroes & a corpse, the story of Operation Mincemeat reads like an international thriller. Unveiling never-before-released material, Macintyre goes into the minds of intelligence officers, their moles & spies, & the German Abwehr agents who suffered the “twin frailties of wishfulness & yesmanship.” He weaves together the eccentric personalities of Cholmondeley & Montagu & their improbable feats into an adventure that saved thousands & paved the way for the conquest of Sicily.

    Here, unsuspected by the Germans, the famous Enigma codes were broken, almost continuously throughout the war. Welchman was a leading figure at Bletchley Park; his brilliant mathematical mind, and imaginative attack on apparently insuperable problems, were of inestimable value in shaping the course of the war and hastening victory. No other book has explained so thoroughly how the job was done, and how so often a flash of genius, an inspired insight, or even a stroke of luck, tipped the balance from failure to success, against all the odds.Gordon Welchman, a talented mathematician, was educated at Marlborough, and Trinity College, Cambridge. He had taken up a post as a fellow of Sidney Sussex College when the war started, and he was an obvious recruit for the expanding codebreaking operations at Bletchley Park. He was awarded the OBE for his war work. After the war he emigrated to the USA, and continued to work on computers and their applications to security and communications. He died in 1985."A publishing history is given on page 252, in Appendix III: First published by McGraw-Hill Book Co. Inc. in 1982, with a British edition appearing in the same year under the Allen Lane imprint. A paperback edition was published by Penguin Books in 1984.

    NBC News calls it, "A historical document of major significance." The focus is on Sir William Stephenson, Britain's urbane spy chief who inspired James Bond.

    It is a tale of double agents, black radio broadcasts, phantom armies, 'Ultra' decrypts, and dummy parachute drops. These diverse tactics were intended to come together to create a single narrative so compelling that it would convince Adolf Hitler of its authenticity.Operation Fortitude was intended to create the false impression that the Normandy landings were merely a feint to disguise a massive forthcoming invasion by this American force in the Pas de Calais. In other words, the success of D-Day – the beginning of the end of the Second World War – was made possible by the efforts of men and women who were not present on the Normandy beaches.Men such as Juan Pujol, a Spanish double-agent (code-name GARBO) who sent hundreds of wireless messages from London to Madrid in the build-up to D-Day relaying supposed intelligence from his fictitious spy network. This allowed the enemy to conclude that the number of Allied divisions preparing to invade was twice the actual number.Men such as R.V Jones, the head of British Scientific Intelligence, who masterminded the dropping of tinfoil confetti from the bomb-bay doors of Lancaster bombers, creating a false impression that a flotilla of Allied ships was heading in the opposite direction to the genuine invasion fleet.Using first hand sources from a wide range of archives, government documents, letters and memos Operation Fortitude builds a picture of what wartime Britain was like, as well as the immense pressure these men and women were working under and insure D-Day succeeded.

    To protect itself, the nation fell back on cunning and camouflage. With Winston Churchill in charge, the British bluffed their way out of trouble—lying, pretending and dressing up in order to survive. The British had developed this uncommon talent during the trench and desert fighting of the First World War, when writers and artists created elaborate camouflages and fiendish propaganda. So successful were these deceptions they gave rise to the German belief that they hadn't been beaten fairly - in which case why not 'have a second go'? By the Second World War, the British were masters of the art. Churchill adored stratagems, ingenious devices and special forces: pretend German radio stations broadcast outrageous British propaganda in German. British geniuses broke German secret codes and eavesdropped on their messages. Every German spy in Britain was captured and many were used to send back false information to their controllers. Forged documents misled their Intelligence. Bogus wireless traffic from entire phantom armies, dummy airfields with model planes, disguised ships and inflatable rubber tanks created a vital illusion of strength. Culminating in the spectacular misdirection that was so essential to the success of D-Day in 1944, Churchill's Wizards is a thrilling work of popular military history. Above all, Nicholas Rankin reveals the true stories of those brave and creative mavericks who helped win what Churchill called 'the war of the Unknown Warriors'.

    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. The compelling narrative shows the crucial effect codebreaking had on the battlefields by explaining the urgency of stopping the wolf pack U-boat attacks in the North Atlantic, 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. Unveiled for the first time, the complete story of codebreaking in World War II has now been told.

    His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century.Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

    citizen recognized its ominous potential. Armed with clear evidence of computer espionage, he began a highly personal quest to expose a hidden network of spies that threatened national security. But would the authorities back him up? Cliff Stoll's dramatic firsthand account is "a computer-age detective story, instantly fascinating [and] astonishingly gripping" (Smithsonian). Cliff Stoll was an astronomer turned systems manager at Lawrence Berkeley Lab when a 75-cent accounting error alerted him to the presence of an unauthorized user on his system. The hacker's code name was "Hunter" -- a mysterious invader who managed to break into U.S. computer systems and steal sensitive military and security information. Stoll began a one-man hunt of his own: spying on the spy. It was a dangerous game of deception, broken codes, satellites, and missile bases -- a one-man sting operation that finally gained the attention of the CIA...and ultimately trapped an international spy ring fueled by cash, cocaine, and the KGB.
