In this comprehensive book, the wartime development of the U-Boat is traced along with the experiences of typical U-Boat crewmen, from recruitment to combat. Germany's World War II U-Boat fleet represented the elite of their naval personnel. In terms of technology, training, tactics and combat successes, the U-Boat Waffe was far superior to that of any other combatant nation. Gordon Williamson examines the operational tactics of the U-Boat fleet, as well as describing the massive bunkers that housed them. Wolf Pack contains material taken from Fortress 3: 'U-Boat Bases and Bunkers 1941-45', Warrior 36: 'Grey Wolf: U-Boat Crewman of World War II' and New Vanguards 51 and 55: 'Kriegsmarine U-Boat 1939-45 (1) and (2)', with the addition of a new section on wartime tactics.
