Pages : 471

Book Description
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 Using previously unpublished decrypts of U-boat signals, selected from the National Archives, along with historic wartime photographs, he tells the stories of the individual U-boats and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.

One Day in August

One Day in August PDF Author: David O'Keefe
Publisher: Icon Books
ISBN: 1785786318
Category : History
Languages : en
Pages : 409

Book Description
'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. 'A fast-paced and convincing book ... that clears up decades of misinformation about the ignoble raid' Toronto Star

Air Power Versus U-Boats - Confronting Hitler’s Submarine Menace In The European Theater [Illustrated Edition]

Air Power Versus U-Boats - Confronting Hitler’s Submarine Menace In The European Theater [Illustrated Edition] PDF Author: A. Timothy Warnock
Publisher: Pickle Partners Publishing
ISBN: 1782898905
Category : History
Languages : en
Pages : 46

Book Description
Includes over 14 photos and maps More than fifty years after World War II, America’s major air power contribution to the war in Europe-in efforts such as Big Week, Regensburg, and Patton’s dash across Europe-live on in the memories of airmen and students of air power. Never before had air forces performed so many roles in so many different types of operations. Air power proved to be extremely flexible: wartime missions included maintaining air superiority, controlling the air space over the battlefield; strategic bombardment, destroying the enemy’s industrial and logistical network; air-ground support, attacking targets on the battlefield; and military airlift, delivering war materiel to distant bases. Perhaps one of the least known but significant roles of the Army Air Forces (AAF) was in antisubmarine warfare, particularly in the European-African-Middle Eastern theater. From the coasts of Greenland, Europe, and Africa to the mid-Atlantic, AAF aircraft hunted German U-boats that sank thousands of British and American transport ships early in the war. These missions supplemented the efforts of the Royal Navy, the Royal Air Force Coastal Command, and the U.S. Navy, and helped those sea forces to wrest control of the sea lanes from German submarines.

You'll discover the tactics, technology, and weapons these vessels used to prey upon Allied warships and unarmed merchantmen alike, how they fought together in wolf packs and alone, how the crews lived beneath the waves, and how they died.

Sighted Sub, Sank Same

Sighted Sub, Sank Same PDF Author: Alan C. Carey
Publisher: Casemate
ISBN: 1612007848
Category : History
Languages : en
Pages : 250

Book Description
A historian examines the U.S. Navy’s efforts to stop Axis forces from attacking Allied merchant ships providing supplies during World War II. During the Second World War, a battle was waged to cut the lifeline of food and armaments sailing across the Atlantic from North America. It evolved into a far-ranging conflict beyond the North Atlantic and the eastern seaboard of the United States. It covered the frigid waters off Iceland down to the warm waters of Florida, through the Caribbean Sea, across the ocean to the Bay of Biscay, the Mediterranean Sea, down to Africa, and across the South Atlantic to Brazil’s southern tip. Nazi Germany’s efforts to deny supplies from reaching Europe came at a high price, losing 783 U-boats and approximately 30,000 men between 1939 and 1945, with land and carrier-based naval air units sinking 83 German submarines of the 159 sunk by American aircraft. Axis forces saw their submarines targeted as well in the Atlantic, with Imperial Japanese submarine I-52 and the Italian Archimede falling victim to American naval aircraft armed with depth bombs or acoustic homing torpedoes. All the dramatic action is captured in Sighted Sub, Sank Same. This book contains over 200 color and black and white photographs, as well as personal interviews, interrogation reports, personal correspondence, and after-action reports, weaving a fascinating history about the naval air campaign in the Atlantic, Caribbean, and Mediterranean Theaters during World War II. Praise for Sighted Sub, Sank Same “Richly illustrates the navy’s battle for the Atlantic from the air.” —The National WWII Museum “Gives the reader a real feeling of that relentless hunt.” —Baird Maritime
