"Tremendous . . . zeroes in on the critical first days of Weserübung and offers a minutely detailed account of the unfolding action."—World War II This book documents the German invasion of Norway, focusing on the events at sea. More than most other campaigns of WWII, Operation Weserübung has been shrouded in mystery, legend and flawed knowledge. Strategic, political and legal issues were at best unclear, while military issues were dominated by risk; the German success was the result of improvisation and the application of available forces far beyond the comprehension of British and Norwegian military and civilian authorities. Weserübung was the first combined operation ever where air force, army and navy operated closely together. Troops were transported directly into battle simultaneously by warship and aircraft, and success required cooperation between normally fiercely competing services. It was also the first time that paratroopers were used. The following days were to witness the first dive bomber attack to sink a major warship and the first carrier task-force operations. The narrative is based on primary sources from British, German and Norwegian archives, and it gives a balanced account of the reasons behind the invasion. With its unrivalled collection of photographs, many of which have never before appeared in print, this is a major new WWII history and a definitive account of Germany's first and last major seaborne invasion. "This is the author's first book but he has a fine natural talent for maritime history. This is a magnificent work."—Work Boat World "A very impressive piece of work that comes highly recommended."—HistoryOfWar.org
