"...this book will give [readers] an understanding of why some boats were more successful than others and why the war was ultimately lost."

"...provides a fine, narrowed history of u-boat tactics that uses wartime source material documents and manuals to explain operational tactics used by German subs during the war. Any collection strong in military strategy will consider this a key survey."
- The Midwest Book Review
"This well-illustrated monograph describes the variety of tactics used by the Kreigsmarine’s submarine force to attack Allied convoys and warships in the Atlantic campaign that did more to threaten Great Britain’s survival than any other threat during the war. The author researched German documents and manuals to describe deck-gun and torpedo attacks, wolfpack tactics, cooperative operations with aircraft, anti-aircraft defense and the use of tethered unpowered gyrocopters for target spotting. He also details some of the technology — armor, anechoic coating, flak guns, homing torpedoes — that enhanced and changed the tactics as the war progressed." -Seapower (June 2011)
