Download or read book Enigma written by Hugh Sebag-Montefiore and published by Weidenfeld & Nicolson. This book was released on 2011-07-21 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complete story of how the German Enigma codes were broken. Perfect for fans of THE IMITATION GAME, the new film on Alan Turing's Enigma code, starring Benedict Cumberbatch. Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost, their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book tells the whole Enigma story: its original invention and use by German forces and how it was the Poles who first cracked - and passed on to the British - the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable.

Available in PDF, EPUB and Kindle. Book excerpt: 'Turing writes on codebreaking with understandable authority and compelling panache.' - Michael Smith, bestselling author of Station X. The Enigma cipher was supposed to be the German's impenetrable defence for its military communications against prying eyes during World War II. All manner of secrets were entrusted to it. When the Allies finally managed to crack the code, it heralded a turning point in the war. Written by Dermot Turing - the nephew of famous codebreaker Alan Turing - The Enigma Story reveals the efforts of the codebreakers at Bletchley Park, the machines called 'bombes' specially designed to break it, and the vast resources devoted in America to decrypting German messages. From the cloak-and-dagger heroics of men like Hans-Thilo Schmidt and Gustave Bertrand to the brilliant mathematical discoveries of men like Henryk Zygalski and Dilly Knox to the fraught decision-making of Allied High Command, the battle for the code was at the heart of the Allied victory in World War II. This extraordinary tale of intrigue, ingenuity and courage brings to life the complete story of the Enigma in a lively and entertaining narrative.

Download or read book Seizing the Enigma written by David Kahn and published by Frontline Books. This book was released on 2012-02-02 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: “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).

Available in PDF, EPUB and Kindle. Book excerpt: The British, Soviets, and Americans unite in this chapter of the six-volume WWII history by the legendary prime minister and Nobel Prize recipient. The Grand Alliance describes the end of an extraordinary period in British military history, in which Britain stood alone against Germany. Two crucial events brought an end to Britain’s isolation. First was Hitler’s decision to attack the Soviet Union, opening up a battle front in the East and forcing Stalin to look to the British for support. The second was the bombing of Pearl Harbor. US support had long been crucial to the British war effort, and here, Winston Churchill documents his efforts to draw the Americans to aid, including correspondence with President Roosevelt. This book is part of the six-volume account of World War II told from the unique viewpoint of a British prime minister who led his nation in the fight against tyranny. In addition to the correspondence with FDR, the series is enriched with extensive primary sources. We are presented with not only Churchill’s retrospective analysis of the war, but also memos, letters, orders, speeches, and telegrams, day-by-day accounts of reactions as the drama intensifies. Throughout these volumes, we listen as strategies and counterstrategies unfold in response to Hitler’s conquest of Europe, planned invasion of England, and assault on Russia, in a mesmerizing account of the crucial decisions made as the fate of the world hangs in the balance. “A masterly piece of historical writing . . . complete with humor and wit.” —The New Yorker

Download or read book Alan Turing The Enigma written by Andrew Hodges and published by Princeton University Press. This book was released on 2014-11-10 with total page 777 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
