Amazon.com Product Description (ISBN 0304352039, Paperback)

34 b/w illustrations! In the frigid waters of the Atlantic during WWII, many soldiers died after their subs and ships were destroyed--mostly from exposure while awaiting rescue. Then Donitz developed the "wolf pack" technique: having subs fight in small groups before dispersing again until the next battle. With this strategy, he nearly succeeded in winning the war. From the development of this brilliant tactic to highlights of the wolf packs' major attacks and their last great challenge, Edward includes actual moment-by-moment reports, comments by Donitz, maps, and photos. Trim size: 5 x 7 3/4.
