This important new reference work details all those ships and vessels of the Royal Navy, large and small, which were lost by accident or enemy action, during the twentieth century, from the end of the World War, to the last years of the century. In all, the fates of over 2,000 ships and small craft are covered, from aircraft carriers and battleships to motor launches, harbor tenders and tugs. Those vessels hired or purchased for wartime service, such as trawlers, paddle steamers and yachts are also listed. The core of the book is taken up by those losses experienced during World War II, but peacetime losses and more recent conflicts such as the Falklands War of 1982 are included. Arranged chronologically, every entry notes the outline details of the vessel, identifies the Commanding Officer, where known, and gives a full and often harrowing account of the circumstances of the loss and the number of casualties. The details come from extensive original research using primary source material wherever possible. This comprehensive record of warship losses, from all causes, suffered by the Royal Navy over the past one hundred years, is the first single-volume work on the subject and represents a major milestone in naval research and publishing.
