The largest, most complex naval battle and its impact on World War II's outcome.

In May 1943, Allied sea and air forces won a stunning, dramatic, and vital victory over the largest and most powerful submarine force ever sent to sea, sinking forty-one German U-boats and damaging thirty-seven others. It was the forty-fifth month of World War II, and by the end of May the Germans were forced to acknowledge defeat and recall almost all of their remaining U-boats from the major traffic lanes of the North Atlantic. At U-Boat Headquarters in Berlin, despondent naval officers spoke of "Black May." It was a defeat from which the German U-boat fleet never recovered. Black May is a triumph of scholarship and narrative, an important work of history, and a great sea story. Acclaimed historian Michael Gannon, author of Operation Drumbeat, has done enormous research and produced the most thoroughly documented study ever done of these battles. In his compelling historical saga, the people are as significant as the technical information. Given the strategic importance of the events of May 1943, it is natural to ask, How did Black May happen and why? Who or what was responsible? Were new Allied tactics adopted or new weapons employed? This book answers those questions and many others. Drawing on original documents in German, British, U.S., and Canadian archives, as well as interviews with surviving participants, Gannon describes the exciting sea and air battles, frequently taking the reader inside the U-boats themselves, aboard British warships, onto the decks of torpedoed merchant ships, and into the cockpits of British and U.S. aircraft. Throughout, Gannon tells the Black May story from both the German and Allied perspectives, often using the actual words of captains and crews. Finally, he allows the reader to "listen in" on secretly recorded conversations of captured U-boat men in POW quarters during that same incredible month, giving intimate and moving access to the thoughts and emotions of seamen that is unparalleled in naval literature. Rarely, if ever, has the U-boat war been presented so accurately, so graphically, and so personally as in Black May.

A Washington Post Notable Book In March 1941, after a year of devastating U-boat attacks, the British War Cabinet turned to an intensely private, bohemian physicist named Patrick Blackett to turn the tide of the naval campaign. Though he is little remembered today, Blackett did as much as anyone to defeat Nazi Germany, by revolutionizing the Allied anti-submarine effort through the disciplined, systematic implementation of simple mathematics and probability theory. This is the story of how British and American civilian intellectuals helped change the nature of twentieth-century warfare, by convincing disbelieving military brass to trust the new field of operational research.

Investigating the employment of British aircraft against German submarines during the final years of the First World War, this new book places anti-submarine campaigns from the air in the wider history of the First World War. The Royal Naval Air Service invested heavily in aircraft of all types—aeroplanes, seaplanes, airships, and kite balloons—in order to counter the German U-boats. Under the Royal Air Force, the air campaign against U-boats continued uninterrupted. Aircraft bombed German U-boat bases in Flanders, conducted area and ‘hunting’ patrols around the coasts of Britain, and escorted merchant convoys to safety. Despite the fact that aircraft acting alone destroyed only one U-boat during the war, the overall contribution of naval aviation to foiling U-boat attacks was significant. Only five merchant vessels succumbed to submarine attack when convoyed by a combined air and surface escort during World War I. This book examines aircraft and weapons technology, aircrew training, and the aircraft production issues that shaped this campaign. Then, a close examination of anti-submarine operations—bombing, patrols, and escort—yields a significantly different judgment from existing interpretations of these operations. This study is the first to take an objective look at the writing and publication of the naval and air official histories as they told the story of naval aviation during the Great War. The author also examines the German view of aircraft effectiveness, through German actions, prisoner interrogations, official histories, and memoirs, to provide a comparative judgment. The conclusion closes with a brief narrative of post-war air anti-submarine developments and a summary of findings. Overall, the author concludes that despite the challenges of organization, training, and production the employment of aircraft against U-boats was largely successful during the Great War. This book will be of interest to historians of naval and air power history, as well as students of World War I and military history in general.

"In Defeating the U-boat: Inventing Antisubmarine Warfare, Newport Paper 36, Jan. S. Breemer tells the story of the British response to the German submarine threat. His account of Germany's 'asymmetric' challenge (to use the contemporary term) to Britain's naval mastery holds important lessons for the United States today, the U.S. Navy in particular. The Royal Navy's obstinate refusal to consider seriously the option of convoying merchant vessels, which turned out to be key to the solution of the U-boat problem, demonstrates the extent to which professional military cultures can thwart technical and operational innovation even in circumstances of existential threat. Although historical controversy continues to cloud this issue ... Breemer ends his lively and informative study with some general reflections on military innovation and the requirements for fostering it."--Foreword.

On June 15, 1942, as thousands of vacationers lounged in the sun at Virginia Beach, two massive fireballs erupted just offshore from a convoy of oil tankers steaming into Chesapeake Bay. While men, women, and children gaped from the shore, two damaged oil tankers fell out of line and began to sink. Then a small escort warship blew apart in a violent explosion. Navy warships and aircraft peppered the water with depth charges, but to no avail. Within the next twenty-four hours, a fourth ship lay at the bottom of the channel— all victims of twenty-nine-year-old Kapitänleutnant Horst Degen and his crew aboard the German U-boat U-701. In The Burning Shore, acclaimed military reporter Ed Offley presents a thrilling account of the bloody U-boat offensive along America’s east coast during the first half of 1942, using the story of Degen’s three war patrols as a lens through which to view this forgotten chapter of World War II. For six months, German U-boats prowled the waters off the eastern seaboard, sinking merchant ships with impunity, and threatening to sever the lifeline of supplies flowing from America to Great Britain. Degen’s successful infiltration of the Chesapeake Bay in mid-June drove home the U-boats’ success, and his spectacular attack terrified the American public as never before. But Degen’s cruise was interrupted less than a month later, when U.S. Army Air Forces Lieutenant Harry J. Kane and his aircrew spotted the silhouette of U-701 offshore. The ensuing clash signaled a critical turning point in the Battle of the Atlantic—and set the stage for an unlikely friendship between two of the episode’s survivors. A gripping tale of heroism and sacrifice, The Burning Shore leads readers into a little-known theater of World War II, where Hitler’s U-boats came close to winning the Battle of the Atlantic before American sailors and airmen could finally drive them away.

In 1942 German U-boats turned the shipping lanes off Cape Hatteras into a sea of death. Cruising up and down the U.S. eastern seaboard, they sank 259 ships, littering the waters with cargo and bodies. As astonished civilians witnessed explosions from American beaches, fighting men dubbed the area "Torpedo Junction." And while the U.S. Navy failed to react, a handful of Coast Guard sailors scrambled to the front lines. Outgunned and out-maneuvered, they heroically battled the deadliest fleet of submarines ever launched. Never was Germany closer to winning the war. In a moving ship-by-ship account of terror and rescue at sea, Homer Hickam chronicles a little-known saga of courage, ingenuity, and triumph in the early years of World War II. From nerve-racking sea duels to the dramatic ordeals of sailors and victims on both sides of the battle, Hickam dramatically captures a war we had to win--because this one hit terrifyingly close to home.

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.
