Description: The German port city of Wilhelmshaven was bombed twice in 1943 -- once by the USAAF on January 27, and again by the RAF Bomber Command on February 11-12. These aerial reconnaissance images show Wilhelmshaven before and after the two bombings. The second bombing, carried out at night, was especially challenging because of dense cloud cover. Planes equipped with the RAF's newly developed H2S ground-mapping radar located strategic targets, then illuminated them with parachute flares. A successful strike on a naval ammunition dump south of Wilhelmshaven caused widespread destruction of dockyards and the city.
