“In his book, author Gordon Williamson has a look at how submarines operated at various stages of the war. There are sections on associated equipment, offensive and defensive weapons/equipment, and various defensive tactics used. This latter was more and more important as the war went against the German submarine fleet. All of this is illustrated by a goodly selection of period photographs and that artwork of Ian Palmer, who shows some very well done charts of how both the submarines and Allied shipping dealt with the submarine war. It makes for a book I found quite engrossing and one that I can easily recommend to you.” —Scott Van Aken, Modeling Madness (November 2010)

“...this book will give[readers] an understanding of why some boats were more successful than others and why the war was ultimately lost.” —Glen Porter, www.hyperscale.com (February 2011)

“...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
