This is the fully revised and updated edition of the first comprehensive account of every peacetime submarine disaster from 1774 to the present day. By examining many of the sinkings in considerable detail, analyzing what went wrong and describing the attempts made to rescue the crew and the vessel, Edwyn Gray traces the development of the submarine from the earliest experimental submersibles of the late 18th century, to the nuclear powered monsters of today. The appendices include the most comprehensive and accurate list of submarine disasters ever printed, in the compilation of which the author has had the cooperation of the US, French, Italian, Danish and Japanese Navies, as well as the RN Submarine Museum and the German U-Boat Archive.
