Download or read book Ultra Versus U Boats written by Roy Conyers Nesbit and published by Casemate Publishers. This book was released on 2009-04-17 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Keeping the Atlantic sea-lanes open was a vital factor in the fight against Nazi Germany. In the battle to protect merchant shipping from the menace of surface raiders and U-boats, Allied resolve and resources were tested to the utmost. The story of the extraordinary measures that were taken to combat the threat, at sea and in the air, has often been told. But there is one crucial element in this prolonged campaign that has still not been fully appreciated the role of code-breaking, in particular the decryption of secret signals transmitted by German Enigma machines. And this is the focus of Roy Nesbits fascinating new account of the Battle of the Atlantic. Using previously unpublished decrypts of U-boat signals, selected from the National Archives, along with historic wartime photographs, he tells the stories of the individual U-boats and describes their fate. Their terse signals reveal, perhaps move vividly than conventional communications could do, the desperate plight of the U-boatmen as they struggled against increasingly effective Allied countermeasures that eventually overwhelmed them.

Available in PDF, EPUB and Kindle. Book excerpt: The problem addressed is the extent to which the United States Navy used Ultra, or Special Intelligence, in the campaign against the German U-boats. Information was gathered through published and unpublished sources. Through a chronological approach, United States Navy involvement is traced from entry into the war until its conclusion. Many factors are involved in the final outcome of the war and Ultra is only one. The Battle of the Atlantic was long and gruesome rather than short and spectacular. The United States Navy used Ultra along with technology, tactics, brilliant leadership and courageous men at sea to win the Battle of the Atlantic in World War II. The lessons for the future are clear. If the United States intends to oppose the Soviet submarine force at sea anywhere in the world, then we must maintain the lead in intelligence, tactics and technology. Further, and most importantly, we must strive to regain superiority of forces in those ocean areas where our interests are at stake.

Download or read book One Day in August written by David O'Keefe and published by Icon Books. This book was released on 2020-11-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'A lively and readable account' Spectator 'A fine book ... well-written and well-researched' Washington Times In less than six hours in August 1942, nearly 1,000 British, Canadian and American commandos died in the French port of Dieppe in an operation that for decades seemed to have no real purpose. Was it a dry-run for D-Day, or perhaps a gesture by the Allies to placate Stalin's impatience for a second front in the west? Historian David O'Keefe uses hitherto classified intelligence archives to prove that this catastrophic and apparently futile raid was in fact a mission, set up by Ian Fleming of British Naval Intelligence as part of a 'pinch' policy designed to capture material relating to the four-rotor Enigma Machine that would permit codebreakers like Alan Turing at Bletchley Park to turn the tide of the Second World War.

Download or read book Very Special Intelligence written by Patrick Beesly and published by Pen and Sword. This book was released on 2015-06-02 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operational Intelligence Centre was the nerve centre of the British Admiralty in World War II, dedicated to collecting, analyzing and disseminating information from every possible source which could throw light on the intentions and movements of German naval and maritime forces. OIC labored tirelessly, despite early disappointments, to supply the Navy and RAF with the intelligence that would enable them to defeat Hitler and his admirals. Patrick Beesly, an insider drawing on considerable personal knowledge, reveals, in full, the compelling story of OIC. He throws light on dramatic episodes such as the hunt for the Bismarck; the tragedy of Convoy PQ17; the long war against the U-boats; and on many other significant events critical to the course of the war. Very Special Intelligence, here presented with a new Introduction which sets the work in context and takes account of new research, is the fascinating story of an organization which contributed so much to Allied success.

The chapters cover her construction, crew and commanders, combat history, general Type IX operations, naval intelligence, the eight fatal German mistakes that doomed the boat, and her capture, transportation, and restoration for posterity. The contributors to this fascinating volume--a Who's Who of U-boat historians--include: Erich Topp (U-Boat Ace, commander of U-552); Eric Rust (Naval Officers Under Hitler); Timothy Mulligan (Neither Sharks Nor Wolves); Jak Mallman Showell (Hitler's U-boat Bases); Jordan Vause (Wolf); Lawrence Patterson (First U-boat Flotilla); Mark Wise (Enigma and the Battle of the Atlantic); Keith Gill (Curator, Museum of Science and Industry), and Theodore Savas (Silent Hunters; Nazi Millionaries).
Download or read book Churchill s Greatest Fear written by Richard Doherty and published by Pen and Sword. This book was released on 2015-11-30 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Battle of the Atlantic (Churchill's term) was arguably the pivotal campaign of the Second World War it was certainly the longest starting with the sinking of RMS Athenia on 3 September 1939 and ending with the torpedoing of SS Avon Dale on 7 May 1945.This superbly researched work covers all the major aspects of The Battle, balancing the initial advantages of Admiral Doenitz's U-Boat force, the introduction of the convoy system, the role of the opposing surface fleets and air forces, relative strengths and the all important technical developments. Intelligence particularly the Bletchley Park intercepts played an increasingly important part in the final outcome.The author concludes that May 1943 was the moment when the Allies seized the initiative and, despite desperate German efforts, never lost their advantage.Using official records, personal accounts and a wealth of historical research, this work gives the reader a splendidly concise yet broad account of the course of the campaign, the men who fought it on both sides and the critical moments and analysis of the outcome.

Available in PDF, EPUB and Kindle. Book excerpt: “A gripping narrative” of the German submarines that nearly changed the outcome of World War II from the author of Dönitz and the Wolf Packs (Naval Review). In essence, this is the story of U-223, commanded by Karl-Jurgen Wächter from the time of her commissioning in Kiel in January 1943 through a murderous career to her eventual but dramatic demise in the Mediterranean in March 1944. At the same time, the book covers the declining fortunes of the U-boat arm as a whole from early 1943 when it seemed invincible and seriously threatened the Allies with defeat to the end of the war. “An intimate narrative, one driven by human endurance and frailty.” —Amsterdam Nautical College Newsletter
Download or read book The Battle of the Atlantic and Signals Intelligence written by David Syrett and published by Boydell & Brewer. This book was released on 2018-10-24 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the U-boats situations and trends written by the staff of the Admiralty's Operational Intelligence Centre during the Second World War. Based largely on communications intelligence, the U-boat situations and trends were designed to inform a small number of senior officers and high officials of the latest events and developments in the Allied war against the U-boats. The Battle of the Atlantic and the war against the U-boats was the longest and the most complex naval battle in history. In this huge conflict which sprawled across the oceans of the world the U-boats sank 2,828 Allied merchant ships while the Allies destroyed more than 780 German U-boats. These documents relate on a weekly, and in some cases a daily, basis exactly what the Allies knew concerning the activities of the U-boats during the Battle of the Atlantic.

Download or read book Hitler s U Boat War written by Clay Blair and published by Modern Library. This book was released on 2010-07-21 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clay Blair's best-selling naval classic Silent Victory: The U.S. Submarine War Against Japan, is regarded as the definitive account of that decisive phase of the war in the Pacific. Nine years in the making, Hitler's U-boat War is destined to become the definitive account of the German submarine war against the Allies, or "The Battle of the Atlantic." It is an epic sea story, the most arduous and prolonged naval battle in all history. For a period of nearly six years, the German U-boat force attempted to blockade and isolate the British Isles, in hopes of forcing the British out of the war, thereby thwarting the Allied strategic air assault on German cities as well as Overlord, the Allied invasion of Occupied France. Fortunately for the Allies, the U-boat force failed to achieve either of these objectives, but in the attempt they sank 2,800 Allied merchant ships, while the Allies sank nearly 800 U-boats. On both sides, tens of thousands of sailors perished. The top secret Allied penetration of German naval codes, and, conversely, the top secret German penetration of Allied naval codes played important roles in the Atlantic naval battle. In order to safeguard the secrets of codebreaking in the postwar years, London and Washington agreed to withhold all official codebreaking and U-boat records. Thus for decade upon decade an authoritative and definitive history of the Battle of the Atlantic could not be attempted. The accounts that did appear were incomplete and full of errors of fact and false interpretations and conclusions, often leaving the entirely wrong impression that the German U-boats came within a whisker of defeating the Allies, a myth that persists. When London and Washington finally began to release the official records in the 1980s, Clay Blair and his wife, Joan, commenced work on this history in Washington, London, and Germany. They relied on the official records as well as the work of German, British, American, and Canadian naval scholars who published studies of bits and pieces of the story. The end result is this magnificent and monumental work, crammed with vivid and dramatic scenes of naval actions and dispassionate but startling new revelations and interpretations and conclusions about all aspects of the Battle of the Atlantic. The Blair history will be published in two volumes. This first volume, The Hunters, covers the first three years of the war, August 1939 to August 1942. Told chronologically, it is subdivided into two major sections, the War Against the British Empire, and the War Against the Americas. Volume II, The Hunted, to follow a year later, will cover the last years of the naval war in Europe, August 1942 to May 1945, when the Allies finally overcame the U-boat threat. Never before has Hitler's U-boat war been chronicled with such authority, fidelity, objectivity, and detail. Nothing is omitted. Even those who fought the Battle of the Atlantic will find no end of surprises. Later generations will benefit by having at hand an account of this important phase of World War II, free of bias and mythology.
