From 1939 until 1942, Hitler's U-boats-the submarine fleet dubbed the "gray wolves"-threatened to accomplish what his air force had been unable to achieve: to starve Britain into submission. The ensuing struggle for control of the storm-tossed Atlantic trade routes became a full-scale war-within-a-war, and one which led to astounding losses: Allied powers would lose more than fifty thousand men, and fifteen million tons of shipping, over the course of the conflict.Through exclusive interviews with survivors on both sides-including those given for the first time by former U-boat crew members-historian and documentary producer Andrew Williams provides a riveting account of these crucial years of battle. Vividly recreating the claustrophobic and dangerous life on board, The Battle of the Atlantic succeeds in encompassing the whole experience of warfare as few other histories have, and forms an important contribution to our understanding of one of the greatest fights of the twentieth century.
