Germany's World War 2 U-Boat fleet was a truly elite fighting force. The U-Boat Waffe represented the cream of Germany's naval personnel, and in terms of technology, training, tactics and combat successes, the German fleet was far superior to that of any other combatant nation. This book tells the complete U-Boat story. The wartime development of the U-Boat is traced from the Type I through to the Type XXI, and the experiences of typical U-Boat crewmen, from recruitment to combat, are brought to life. Operational tactics are examined, and the massive bunkers that housed the U-Boat fleet are described and illustrated. Contains material taken from Fortress 3: 'U-Boat Bases and Bunkers 1941-45', Warrior 36: 'Grey Wolf - U-Boat Crewman of World War II', New Vanguard 51: 'Kriegsmarine U-Boat 1939-45 (1)' and 55: 'Kriegsmarine U-Boat 1939-45 (2)', plus a brand new section on wartime tactics.
