A gripping examination of the Battle of the Barents Sea, fought in the near darkness and icy cold of the northern winter, in which the Kriegsmarine sought to sever the crucial Allied Arctic Convoy route once and for all. The Arctic convoys that passed through the cold, dangerous waters of the Barents Sea formed a vital lifeline – a strategic link in tanks, supplies and above all goodwill between the Western Allies and the Soviet Union. In December 1942, under Operation Regenbogen (Rainbow), the German Kriegsmarine sought to strike a crippling blow on the Arctic convoys and finally sever this all-important sea route. In this fascinating work, renowned naval expert Angus Konstam documents the fate of the Allied Convoy JW 51B as it came under attack from some of the Kriegsmarine's most powerful surface warships – a pocket battleship, a heavy cruiser and six destroyers. Illustrated with stunning battlescene artworks, maps, 3D diagrams and photographs, it explores the David and Goliath struggle between the Allied ships defending the convoy and the powerful German force, until the arrival of the two British cruisers tipped the balance of power. The Battle of the Barents Sea, fought amid snowstorms and the darkness of the Arctic night, would prove to be a turning point in the hard-fought war in northern waters, and would test Hitler's patience with his surface fleet to the limit.
