THE U-BOAT WARS 1916-1945 by Terraine, John

New York 1989, Putnam, US first edition, 6 1/2 x 9 1/2, FINE/FINE CONDITION, xx, 841 pages, illustrations, maps, notes, appendices, bibliog, index.  A distinguished historian's definitive account of the development of submarine warfare during and between two world wars.---------------------------------------------Drawing on a wealth of rich new documentary information and analysis, John Terraine offers a masterful examination of the U-boat campaigns in World Wars I and II, particularly the Battle of the Atlantic, 1939-1945, one of this century's most critical battlegrounds. Beginning with the inception of "unrestricted submarine warfare" in 1916, Terraine examines the day-in-and-day-out endeavors of the navies, the shifting tactics and strategies, and the intricate political maneuverings. He explores the previously obscured roles of air power and British intelligence in World War 2 submarine warfare and shows how the Battle of the Atlantic was very nearly lost, how little attention was paid to the lessons of submarine warfare learned during World War I, and how the tide was finally turned just in time. For if the new submarine Germany was bringing into operation in April 1945 had existed in 1944, the results for the Allies might well have been catastrophic.
