The remarkably effective submarines (U-boats) of the German Navy devastated the Allies during the first part of World War II and very nearly brought British and American sea forces to their knees. Military historian Hoyt here describes the years when U-boat "wolf packs" under the command of Admiral Karl Doenitz terrorized the Allies, sinking a third of Britain's battleships in 1939, and how the Allies came back, developing anti-submarine weapons that sent almost three-fourths of the U-boat crews to the bottom of the ocean. The U-Boat Wars is a gripping account of the battles at sea and the men—Doenitz, Churchill, sub-hunter Captain F. J. Walker, and others—who decided the fate of the Atlantic.

“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

The only thing that ever really frightened me during the war was the U-boat peril - Prime Minister Winston Churchill. Churchill, as a former First Lord of the Admiralty, was well versed in the importance of Britain protecting itself at sea. In the opening years of the Second World War, Germanys U-boat (submarine) fleet was tasked with attacking and destroying the supply ships that Britain depended upon for its survival.The U-boats were under the command of Grand Admiral Karl Doenitz who, for much of the war, effectively guided that strategy. There was a very real possibility that the British people would starve if the U-boats succeeded in their campaign. When France fell to the German forces in 1940, Hitlers Ubootwaffe gained a significant asset in five important ports along the Brittany coast - Brest, Lorient, St. Nazaire, La Palace and Bordeaux. The use of these ports put Germanys submarine force hundreds of miles closer to the action in the North Atlantic, the routes of the Allied supply convoys which were operating mainly between Halifax, Nova Scotia and various English port cities. This afforded the U-boats several more days at sea on their deadly patrols than was possible while they had been based in Germany and German-occupied Norway.In this new publication from Philip Kaplan, the massive bunkers or pens constructed in Brittany by the laborers of the German Organisation Todt are revisited. These giant structures, some of which sheltered more than a dozen submarines at a time, still exist because they were built with concrete ceilings more than three meters thick. With equally impressive supporting walls, they suffered relatively little damage in the wartime bombing raids of the Royal Air Force and the US Eighth Army Air Force. Illustrated with more than 150 rare and compelling photo images, this book is a richly rewarding journey back across time to some of the most intriguing and electrifying sites from the war years. The story of the pen shelters and their part in that war is both fascinating and enduring.

In the waning days of World War II, a little-known battle took place under the frozen seas off the coast of Norway . . . and changed the course of the war. In February of 1944, Germany and Japan devised a desperate plan to escape defeat. The Germans would send Japan a submarine—boat U-864—packed with their most advanced rocket and jet aircraft technology. Japan could then reestablish air superiority in the Pacific, drawing the attention of Allied forces long enough for Germany to regroup. Meanwhile, British code breakers, working with the Norwegian underground, had discovered the plan. But even though they were unable to stop the submarine from embarking, the British submarine HMS Venturer was waiting for it at sea. In a cat-and-mouse battle beneath the waves, they hunted one another, each waiting to strike. The Venturer won the game, becoming the only submarine in history to sink another sub in underwater combat. This is the dramatic, action-packed account of one of the greatest unsung victories in military history, and of a historical moment in the annals of naval warfare.

From January to July 1942, more than seventy-five ships sank to North Carolina's "Graveyard of the Atlantic" off the coast of the Outer Banks. A Standard oil tanker sank just sixty miles from Cape Hatteras. German U-boats sank ships in some of the most harrowing sea fighting close to America's shore. Germany's Operation Drumbeat, led by Admiral Karl Donitz, brought fear to the local communities. The U-85 was the first U-boat sunk by American surface forces, and local divers later discovered a rare Enigma machine aboard. Author Jim Bunch traces the destructive history of world war on the shores of the Outer Banks.

Submariners are a tight knit group of men bound together by training and experience, and with a language all their own. That language is perhaps a little vulgar, but never intentionally demeaning, and a little irreverent but still worldly. This work is an attempt to preserve and explain some of these curious guys who so proudly wear a shiny metal pin that looks like a strange pair of fish on their left breast. This process of accumulating this new language begins in Boot Camp, and is added to with every change of duty station the sailor undergoes. It is heard aboard the boats and, unknowingly, by family members who can't understand terms like head, deck, and overhead, and who think SOS is a distress signal.
