Three large raids in the south-east, including London. Portsmouth and Southampton attacked. German invasion postponed again (till the 14th).
Night: London and Merseyside attacked.
Weather: Mainly fine with some local showers. Cloud in the Channel and Thames Estuary.
After reconnaissance flights at lunchtime, Luftflotte 2 put up three big raids and Luftflotte 3 attacked Southampton. At 2.45 p.m. formations began building up over Calais and Ostend and aimed for London. At 3.45 another wave came in over Folkestone, and was shortly followed by a third. Bombs fell on the City, the docks, Islington and Paddington, and others on Biggin Hill, Kenley, Brooklands and Hornchurch.
Simultaneously two raids from Seine Bay and Cherbourg had linked up over Selsey Bill and despite harrying fighters dropped bombs on Southampton and Portsmouth.
An hour later waves of Bf 109s appeared over Kent, some attacking the Dover balloons. Another force attacked a convoy and single aircraft headed for Colerne, Kenley, Detling and Eastchurch. The convoy ‘Peewit’ was dive-bombed, its escort ‘Atherstone’ being disabled.
In all this widespread activity, Fighter Command flew 678 sorties. The scoreboard at the end of the day was in reality depressing, RAF losses being 29 aircraft, 17 pilots killed and 6 wounded, compared with German casualties for the 24 hours of 25 aircraft. KG 26 was the worst hit, with eight He 111s shot down. At the time it was estimated German losses were far higher, but the red in the British balance sheet on the final reckoning is accounted for by the fact that many squadrons became entangled with the escorting formations who attacked from above.
