orensic analysis of the design, operation and loss of Germany s greatest battleship and draws on survivors accounts and the authors combined decades of experience in naval architecture and command at sea. Their investigation into every aspect of this battleship has taken fifty-six years of painstaking research, during which time they conducted extensive interviews and corresponded with the ship s designers and the survivors of the battle of the Denmark Strait and Bismarck s final battle. Albert Schnarke, for instance, the former gunnery officer of Tirpitz, Bismarck s sister ship, aided the authors greatly by translating and supplying manuscript materials from those who had participated in the design and operations. Survivors of Bismarck s engagements contributed to this comprehensive study including D B H Wildish, RN, damage control officer aboard HMS Prince of Wales, who located photographs of battle damage to his ship. After the wreck of Bismarck was discovered in June 1989, the authors served as technical consultants to Dr Robert Ballard, who led three trips to the site. Film maker and explorer James Cameron has contributed a chapter, which gives the reader a comprehensive overview of his deep-sea explorations on Bismarck and it is illustrated with his team s remarkable photographs of the wreck. The result of nearly six decades of research and collaboration, this new work is an engrossing and encyclopaedic account of the events surrounding one of the most epic naval battles of World War Two. And Battleship Bismarck finally resolves some of the major questions around her career, not least the most profound one of all: Who sank the Bismarck, the British or the Germans?
