This book traces the development of the U-boat threat from the Brandtaucher, designed by Wilhelm Bauer, the father of the German submarine arm, in 1850, through to the commissioning of Germany's first U-boat to go into service, the U-1, in 1906. It then covers the main types of World War I U-boat, detailing the operational history of the U-boat service in depth, with a particular focus on the campaigns in the Atlantic and Mediterranean, as well as the slow build up of anti-submarine measures by the allies."@en . . .
