By 1942 the Kreigsmarine was largely confined to harbour but none the less the Royal Navy still pursued it. In February 1942, two battlecruisers escaped with a daring, daylight sortie up the channel. Following this, there was a series of battles in Arctic waters which left the Scharnhorst sunk in a blizzard by HMS Duke of York and the Tirpitz capsized by giant bombs. This second volume describes the disproportionate effort expended in trying to sink the finest warships ever built. The Prinz Eugen for example withstood a nuclear explosion after the war ended.
