The late Dr. David Westward was chiefly known as a military historian with a profound knowledge of German military weapons. However, one aspect of naval history fascinated him – the U-boat war of 1939-1945. His study of the Type VII U-boat (see No. 237 above) was widely-acclaimed. In this current book, he consults hitherto lightly-researched material in the Bundesarchiv, examining pre-war German efforts to build up and reinvigorate the U-boat theory of war, and their clandestine research of the 1920s and early 1930s which led to an aggressive construction programme once the Nazi Party assumed power in 1933. The entire U-boat campaign is examined, in all its many aspects, and the development of the Type-XXI electro-U-boats is fully explained – see Item No. 124 above. FINE copy.
