This is the story of an air campaign in which each bomb could dramatically influence the course of the war. In January 1942, the powerful German battleship Tirpitz sailed into her new base in a Norwegian fjord, within easy reach of the Arctic Convoys. Her destruction suddenly became a top Allied priority. But sinking a modern and formidably armed battleship was no easy task, especially when she lay secure in a remote, mountainous fjord, protected by anti-torpedo nets, radar, flak guns and smoke generators. This book charts the full, complex story of the air war against Tirpitz, from the Fleet Air Arms failed torpedo attack at sea, the RAFs early Halifax raids, and the carrier-borne Barracuda airstrikes of Operations Mascot, Tungsten and Goodwood, to the three Tallboy attacks that finally crippled and sank her. With detailed maps and diagrams, it explains the aircraft and ordnance the British had to work with, the evolving strategic situation, and why the task was so difficult.
