Night: London attacked.
Weather: Generally fair but cloudy with light winds.
Main Activity:
An hour separated the first two major raids which began at 9 a.m. In the first there were thirty bombers and 100 fighters; in the second sixty planes.
Crossing the coast at Dungeness the two raids were met in force. Split and harried, neither reached London.
At 10.50 a.m. radar warned of another attack—this time approaching Dorset from Cherbourg. The planes were Bf 110 fighter-bombers escorted by 109s. They were so severely handled by the RAF that they turned back before reaching the coast.
Midday came and with it a fierce battle over Kent. Then at 3.10 p.m. a series of minor sorties was followed by a major raid of more than 100 planes. Thirty reached London. Within fifty minutes 180 more bombers and fighters were plotted approaching Weybridge and Slough on a front of eight miles.
One hundred miles west, forty escorted Heinkel bombers crossed the coast heading for the Westland works at Yeovil. Cloud obscured the target and the Germans were obliged to bomb blind. Sherborne, some miles from Yeovil, took the full impact of the attack.
The Germans had to fight their way in against four British squadrons and they were beset by another four on the way out. Four Hurricanes fell to their gunners and an Bf 110 shot down another.
Two of the British pilots baled out and the third. Wing Commander Constable-Maxwell, shot down by a single bullet puncturing the oil system of his aircraft, force-landed his Hurricane on a beach.
By dusk the last great daylight battle was over and the score was 47 German aircraft destroyed for a loss of 20 RAF fighters and eight pilots killed or wounded.
Just as the JU-87 Stuka had been withdrawn from the battle so now were the twin-engined bombers to be relegated to the night offensive — except for those rare occasions when they could use the clouds to cover their sorties over Britain. Night time mass Luftwaffe bombing (The Blitz) over British cities will continue but during daylight over Britain RAF has definite air supremacy.
And as if to mark the occasion the King appointed Dowding Knight Grand Commander of the Bath.
