"A first hand account of the German U-boat battles of World War II, by one of the very few surviving commanders. This is a story of triumph, disaster and eventual survival against all odds. Herbert Werner was one of the few U-boat commanders whose skill, daring and incredible luck saw him safely through to the end of the war. His is an epic and chilling description of the fearful havoc wrought by one small U-boat on the Atlantic convoys. But easy success ebbed away in the face of ever-improving Allied detection and attack techniques. The hunters became the prey, to suffer appalling losses. Of 842 U-boats launched 779 were sunk, 'iron-coffins' to 28,000 men. Herbert Werner's graphic account of war waged from beneath the sea, of horror and cold, cruel death, is dedicated to the seamen of all nations who died in the Battle of the Atlantic."
