Although countless books have been written about the U-boat war in the Atlantic, precious few facts have come to light about the men who served in the submarines that wrought such havoc on Allied ships. Eager to get beyond the stereotypes perpetuated in movies and novels and find out who these elusive sailors really were, archivist Timothy Mulligan started searching official records. Eventually he went straight to the source, conducting a survey of more than a thousand U-boat officers and enlisted men and interviewing a number of them personally. The result is this character study of the German submarine force that challenges traditional and revisionist views of the service. Mulligan found striking similarities in the men's geographic and social origins, education, and previous occupations, particularly within the specialized engineering and radio branches of the submarine force. The information he gathered establishes quantifiable patterns in age, length of service, and experience, as well as the organization's overall recruitment policies and training standards. The numbers and losses of U-boat personnel are also fully examined. Beyond these objective characteristics, this study lists such subjective factors as morale, treatment of enemy ship survivors, and the relationship of the submariners to the Nazi regime, and it confirms a serious crisis in morale in late 1943. The roles played by the head of the U-boat arm, Grand Admiral Karl Donitz, and its organizational chief, Admiral Hans-Georg von Friedeburg, are thoroughly addressed. Mulligan concludes that the U-boat arm quickly evolved from a handpicked elite to a more representative sample of the German navy at large but continued to be treated as an elite force. The only comprehensive investigation yet published, this book also draws on POW interrogations of U-boat survivors and documentation of Kriegsmarine personnel policy obtained from German archives.

During the Second World War over 250 Allied warships from a dozen navies were sent to the bottom by German U-boats. This ground-breaking study provides a detailed analysis of every sinking for which source material survives from both the Allied and the German sides, resulting in detailed treatment of the fate of 110 vessels, with the remainder summarised in an extensive appendix. Uniquely, each entry is built around a specialist translation of the relevant segment of the war diary (log) of the U-boat in question, taken directly from the surviving originals – remarkably, this represents the first large-scale publication of the U-boat war diaries in any language. The book offers a wealth of new information, not only with respect to the circumstances of the sinkings from both the Allied and German perspectives, but also to the technical environment in which they lived as well as the fate of the crews. The entries include background details on the vessels concerned and the men involved, with a selection of rare and carefully chosen photos from archives and collections around the world. Each entry is itself a compelling narrative, but is backed with a list of sources consulted, including documents, published works and websites. A decade in the making, this is probably the most important book on the U-boat war to be published for many a year

The accepted historical narrative of the Second World War predominantly assigns U-boats to the so-called 'Battle of the Atlantic', almost as if the struggle over convoys between the new world and the old can be viewed in isolation from simultaneous events on land and in the air. This has become an almost accepted error. The U-boats war did not exist solely between 1940 and 1943, nor did the Atlantic battle occur in seclusion from other theatres of action. The story of Germany's second U-boat war began on the first day of hostilities with Britain and France and ended with the final torpedo sinking on 7 May 1945. U-boats were active in nearly every theatre of operation in which the Wehrmacht served, and within all but the Southern Ocean. Moreover, these deployments were not undertaken in isolation from one another; instead they were frequently interconnected in what became an increasingly inefficient German naval strategy. This fascinating new book places each theatre of action in which U-boats were deployed into the broader context of the Second World War in its entirety while also studying the interdependence of the various geographic deployments. It illustrates the U-boats' often direct relationship with land, sea and aerial campaigns of both the Allied and Axis powers, dispels certain accepted mythologies, and reveals how the ultimate failure of the U-boats stemmed as much from chaotic German military and industrial mismanagement as it did from Allied advances in code-breaking and weaponry.
