Critical Convoy Battles Of Wwii

"Remarkable...a feat of historical reconstruction."—Paul Kennedy, New York Times bestselling author of The Rise and Fall of the Great Powers The Battle of the Atlantic, the longest continuous campaign of World War II, climaxed in 1943, when Germany came closest to interrupting Allied supply lines and perhaps winning the war. In March of that year, German U-boats scored their last great triumph, destroying nearly 150,000 tons of supplies and fuel. • Blow-by-blow account of the largest convoy battle of the war • Analyzes the tactics, technology, and intelligence of both sides

The Battle of the Atlantic, the longest continuous campaign of World War II, climaxed in 1943, when Germany came closest to interrupting Allied supply lines and perhaps winning the war. In March of that year, German U-boats scored their last great triumph, destroying nearly 150,000 tons of supplies and fuel.

This book tells the saga of a German front-line U-Boat, U-I 7S, which, with her compatriots, very nearly severed Britain's lifeline across the Atlantic, and which culminated in a critical battle around Convoy HX-233 in the Spring of 1943. The author was a witness to the battle and this, combined with the meticulous research of original documents and his use of eye witness accounts from both the Allied and German sides, has resulted in a quite remarkable piece of work in which no stone has been left unturned in his desire to reconstruct exactly what happened both to the U-boats and their quarry in the crucial months of 1943. But the book is much more than a description of a single battle for the author takes this particular event as a microcosm to explain the strategic and tactical background, the technical developments on both sides, and the operational experiences that occurred throughout the whole of the War. He is particularly astute at evaluating both the US and British contributions to the Atlantic convoy battles and explaining the logistical problems faced by the Kriegsmarine.

German submarine operations against allied convoys, during March 1943 is critically analyzed from an operational perspective. The theater commander’s operational scheme is dissected for the purpose of identifying lessons which can be applied to the planning and execution of today’s theater operations. A brief historical account of the early phases of the war and the events and decisions which preceded the critical convoy battles will be followed by an analysis of the operational scheme employed by Admiral Dönitz. German victory during the spring offensive clearly demonstrated numerous operational successes, a reasonably well conceived operational plan, and proof positive of the potential for a larger scale victory. Yet history recorded Germany’s ultimate defeat in the Battle of the Atlantic. This analysis identified three significant flaws which led to the German demise; first, strategic guidance and operational means were inadequately reconciled which prevented the proper execution of the operational plan; second, operational intelligence and reconnaissance were inadequately exploited; third, Germany failed to coordinate and execute joint operations between service arms, specifically the lack of air assets in support of vital U-boat operations. Clearly one must conclude a reasonable operational plan has marginal chance for success when strategic guidance and joint coordination are incompatible with theater objective accomplishment.

The author of The First Day on the Somme details a naval skirmish that became a turning point for the Battle of the Atlantic during World War II. Winston Churchill wrote, “The only thing that ever really frightened me during the war was the U-boat peril.” Had the convoy link between North America and Britain been broken, the course of World War II would have been different. There was a period during the winter of 1942-43 when the Germans almost cut the North Atlantic lifeline. In the first twenty days of March, 1943, the Germans sank ninety-seven Allied merchant ships—twice the rate of replacement. During the same period, seven U-boats were lost and fourteen put in service. No wonder Churchill was worried. Early in March, 1943, Convoys SC122 and HX229 sailed from New York harbor for England, and Admiral Doenitz deployed forty-two U-boats to entrap them. Twenty-one merchant ships were sunk in the ensuing battle. The Germans called it “the greatest convoy battle of all time.” This book documents the convoys, every maneuver of the merchant ships, their escort vessels, the long-range aircraft cover, and the attacking U-boats in a powerful narrative reminiscent of Nicholas Monsarrat’s bestselling novel The Cruel Sea. In many ways, this book could be the story of any of the hundreds of convoys that sailed the ocean during the war. Middlebrook also elucidates three controversial aspects of the Battle of the Atlantic: why there was an “Air Gap” long after full air cover could have been provided, why the convoys had to sail with dangerously weak naval escorts, and how the Allied outwitted the Germans in the radio decoding war.

In the final year of World War I, Germany made its first attempt to wage submarine warfare off faraway shores. Large, long-range U-boats (short for unterseeboot or "undersea boat") attacked Allied shipping off the coasts of the U.S., Canada and West Africa in a desperate campaign to sidestep and scatter the lethal U-boat defenses in European waters. Commissioned in 1917, U-156 raided commerce, transported captured cargo and terrorized coastal populations from Madeira to Cape Cod. In July 1918, the USS San Diego was sunk as it headed into New York Harbor--the opening salvo in a month-long series of audacious attacks by U-156 along the North American coast. The author chronicles the campaign from the perspective of Imperial Germany for the first time in English.
