The most extensive and reliable data available on Axis submarine victories are presented in this comprehensive reference. First published in 1983 and now revised to reflect information recently uncovered, the book is the product of years of research by Jurgen Rohwer, a leading expert in the field. Taken from widely dispersed sources, the information offers a detailed compilation of German, Italian, Japanese, Romanian, Finnish, and Vichy-French submarine successes and claims against Allied and neutral ships in every theater of the war at sea. Each entry gives the date of the attack; the nationality, name, and commander of the attacking submarine; a reference map with the precise location of the attack; and the type, tonnage, nationality, and name of ship sunk. Additional information, aimed at resolving controversial claims and clarifying previously inexact data, is also provided. Separating fact from wartime propaganda and myth, the book will serve as an indispensable guide to submarine operations and military and merchant shipping losses.
