Born at the Casablanca Conference in January 1943, the Combined Bomber Offensive—codenamed Pointblank—married the RAF’s night area bombing with the USAAF’s daylight precision campaign into a single, devastating industrial strategy. Officially approved on 10 June 1943, the plan targeted seventy-six precision systems: fighter factories, submarine yards, and oil refineries. By day, the Eighth Air Force’s heavy bombers struck specific aiming points; by night, the Lancasters and Halifaxes of Bomber Command flattened the surrounding cities. The objective was to erode Luftwaffe fighter strength before Operation Overlord. It was a brutal calculus—unescorted deep penetrations cost staggering losses—but by spring 1944 the German air force had been bled white, and the skies over Normandy belonged to the Allies.
