The Germans have finally abandoned the mass bombing of London by day in view of their heavy losses. No more bombers by day. Instead, the capital is bombed by fighters (they break through in small groups), accompanied by fighter escorts (which do not carry bombs) at a proportion of eight escorts per fighter. The fighter-bombers fly at an altitude of 8–9,000 metres. It is difficult to detect them, and still harder to give them chase. The moral and material effect of the day raids is generally negligible.
