The Defeat Of The German U Boats

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 collection of true stories featuring German U-boatmen vividly tell what it was like to undergo the terror and tedium of living for weeks on end in a narrow, stinking tube, targeting their counterparts for sudden, sinking death. In these first-person accounts, even the torpedo attacks are routine; what creates terror is the sudden instant when something goes horribly, often fatally, wrong.

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.

"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.

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.

World War I saw the submarine develop into a potent weapon of war. The German submarine campaign almost defeated Britain during the spring of 1917. By striking at the shipping that supplied her, it has been estimated that Britain came within six weeks of starvation.

On a sweltering day in August 1906 U-1, or Unterseeboot 1, meaning underwater boat, was lifted into Kiel's waters for trials; 100 hundred years later Kiel still witnesses the launching of U-boats, modern submarines with fuel cell propulsion systems, built for navies worldwide. In the years in between Germany fought two world wars, in which the U-boat almost defeated the Allies. --The U-boat was one of the most potent weapons of the 20th century, and here Mallmann Showell, perhaps the world's leading U-boat historian, explains how it was developed and designed and then deployed to wreak havoc in European waters and further afield in the Atlantic and the Far East. This is not a dry technical book but a work that looks behind the scenes at the men who built and fought in them. Weapons systems, operational areas, bases, builders and fleet organisation are covered, and as well as dealing with the world wars, the author brings the story up to date with the third, latest, generation of U-boats. The text is augmented by over 300 images, many never published before. --Publisher description.
