A richly illustrated examination of the British raid on the port of St Nazaire: one of the most daring actions of World War II. The port lies at the mouth of the River Loire and in 1942, as well as a U-Boat base, contained the massive 'Normandie' dock, the only facility on the Atlantic coast large enough to accommodate the German pocket battleship Tirpitz. This book tells the story of the raid that denied the use of the dock to the Tirpitz, the sister ship of the Bismarck, and constituted a crucial victory for the British Combined Operations in the Battle of the Atlantic.
