An illustrated exploration of the development, technology, and operations of the Wilde Sau fighters in the night skies over Germany during the Defense of the Reich. In July 1943, Germany's defense against the increasingly effective RAF night bombing campaign almost came to a halt. 'Window' was used—strips of paper with aluminum on one side—dropped by bombers to block German radar. Fortunately for the Luftwaffe, the concept of Wilde Sau for point defense with single-engine fighters had already been developed and would become the cornerstone of Germany's night defense during the summer and autumn of 1943. In this new study, Martin Streetly analyzes the roots, tactics, and implementation of Wilde Sau, exploring the successes and failures through the experiences of pilots who flew Bf 109s, Fw 190s, and Me 262s in battles against the heavy bombers Lancaster and Halifax. Authentic testimonies of Wilde Sau missions come alive through archival photos and new artistic creations of some of the most iconic German fighters of World War II.
