Book excerpt: When the Luftwaffe entered World War 2, its nightfighter force was virtually nonexistent thanks to its leader, Reichmarschall Hermann Göring, who boasted that bombs would never fall on Germany. By mid-1940 his folly was evident; the first night fighter wing was hastily formed with Bf 110s. Initially capable of detecting targets by visual acquisition only, the force greatly improved its effectiveness with the creation of the 'Giant Würzburg' radar chain. By the end of 1942, the night fighter force controlled some 389 fighters and had destroyed 1,291 RAF bombers in that year alone. Complete with first-hand accounts and detailed colour illustrations, this book profiles the many variations of night fighters, and the men who made ace flying them.
