The first major color-illustrated book to capture life on board a U-boat. The text, drawing on letters, diaries, journals, memoirs, prose, poetry and proverb, relates the mundane and the routine, the dramatic and the heroic, fear and resilience as experienced by every man from Kapitänleutnant to Mechaniker. By the end of the war, however, of the 39,000 men who went to sea in the U-boats, 27,491 died in action and a further 5,000 were made prisoners-of-war. Of the 863 U-boats that sailed on operational patrols, 754 were lost. Wolfpack is a vivid and brutally realistic portrait of the lives of the men who fought and died beneath the surface of the Atlantic. -- Adapted from the book jacket.
