Arranged by sea areas and in chronological order, this informative study contains reports of the attacks by Soviet submarines in the Baltic and Black Seas, and the attacks by British and other Allied submarines from Norway to Morocco, including the Mediterranean. This information has been compiled by the renowned German naval historian Jurgen Rohwer, with assistance from experts in Great Britain, France, Poland, Norway, the Netherlands, Italy, Greece, Russia, Finland, Sweden, Turkey, the United States, and Japan. The work not only confirms assessments from earlier publications, but corrects many wartime reports based on insufficient or incorrect observations and claims.
