"This is the first comprehensive English-language study of S-Boat, or schnellboot, actions during World War II in all the theatres where they were deployed." "The operational deployment of the S-Boat in all these theatres is given comprehensive treatment and not purely from the isolated viewpoint of S-Boat warfare, but as an integral part of the overall military objectives of the time. The author analyses the effectiveness of the S-Boat, its successes and Failures, and much of his study is based on war diary entries and previously unseen original sources. Illustrated with an extensive collection of new photographs and specially commissioned maps, the book is an outstanding account of this German naval arm that survived to be the last class of surface warship carrying the offensive to the enemy."--BOOK JACKET.
