Pointblank directive

The Pointblank directive authorised the initiation of Operation Pointblank, the code name for the part of the Allied Combined Bomber Offensive intended to cripple or destroy the German aircraft fighter strength, thus drawing it away from frontline operations and ensuring it would not be an obstacle to the invasion of Northwest Europe. The Pointblank directive of 14 June 1943 ordered RAF Bomber Command and the U.S. Eighth Air Force to bomb specific targets such as aircraft factories, and the order was confirmed when Allied leaders met at the Quebec Conference in August 1943. Up to that point, the RAF and USAAF had mostly been attacking the German industry in their own way – the British by broad night attacks on industrial areas, and the US in "precision attacks" by day on specific targets. The operational execution of the Directive was left to the commanders of the forces. As such, even after the directive, the British continued their night attacks. The majority of the attacks on German fighter production and combat with the fighters were conducted by the USAAF.

In practice, the USAAF bombers made large-scale daylight attacks on factories involved in fighter aircraft production. The Luftwaffe was forced into defending against these raids, and its fighters were drawn into battle with the bombers and their escorts. It was these battles of attrition that reduced the Luftwaffe's fighter pilot strength, despite increases in German aircraft production.

Casablanca directive

At the January 1943 Casablanca Conference, the Combined Chiefs of Staff agreed to conduct the Combined Bomber Offensive (CBO), and the British Air Ministry issued the Casablanca directive on 4 February with the object of:

The progressive destruction and dislocation of the German military, industrial and economic systems and the undermining of the morale of the German people to a point where their capacity for armed resistance is fatally weakened. Every opportunity to be taken to attack Germany by day to destroy objectives that are unsuitable for night attack, to sustain continuous pressure on German morale, to impose heavy losses on German day fighter force and to contain German fighter strength away from the Russian and Mediterranean theatres of war.
