With the pressure off their air bases the RAF was now able to increase its nightly raids on industrial sites in Germany and occupied lands. Because of the inability to correctly target these sites, the raids soon turned into “area bombing”, and German civilian casualties rose. These raids were to reach further into Germany as the war progressed and were greatly increased when American bombers began their sorties.
