1939年二战爆发，为打击英国的贸易航线，德意志帝国战争海军在战争爆发之前的8月份就派出了三艘德意志级袖珍战列舰前往大西洋。相比英军战列舰，德意志级航速更快可以逃脱；相比英军巡洋舰，德意志级装甲和火力更为强大。“斯佩伯爵海军上将”号就是德意志级中最先进的一艘，从1939年8月到11月活跃于印度洋和大西洋的盟国航线之上。由于英国仅有的三艘战列巡洋舰需要布置在本土密切注意德国沙恩霍斯特级战列舰，猎杀德意志级的任务只能交给巡洋舰们。1939年12月13日，轻巡洋舰“阿贾克斯”号、“阿基里斯”号和重巡洋舰“埃克塞特”号在南美拉普拉塔河口发现了“斯佩伯爵”，一番追击战过后，“斯佩伯爵”耗光了自己的弹药，躲进中立国乌拉圭的蒙得维的亚港。乌拉圭政府极力避免卷入战争，留给“斯佩伯爵”的时间只有72小时，她和她的舰员将会面临怎样的命运？

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 Arm's failed torpedo attack at sea, the RAF's 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.
