Thames Estuary
At 1101 hours, two raids were plotted approaching Deal. They combined to form a raid of 25+ aircraft which turned north and entered the Thames Estuary where two convoys were attacked. The enemy were intercepted by our fighters and casualties were inflicted.
Attack on Manston Aerodrome
At 1245 hours, the aerodrome at Manston was attacked by 50 enemy aircraft and damage done to the aerodrome and hangars. Four squadrons and one section of fighters engaged the enemy.
Dover Area
At 0720 hours, a large-scale attack began to develop on Dover and continued until about 0840 hours. There were 11 raids in all, consisting of about 200 aircraft, some of which are reported to been camouflaged in a manner similar to our fighters. RAF establishments at Dover, Rye and Pevensey were attacked but not seriously damaged. The four squadrons sent up to intercept shot down several enemy aircraft. Our own casualties were extremely slight.
From 1400 to 1500 hours, a strong reconnaissance was plotted in the Straits of Dover and carried out and extensive search without approaching the English Coast.
From 1700 hours onwards, about 17 raids were concerned in a further attack on Dover and district. A considerable battle developed during which enemy aircraft were active over Hawkinge and Lympne. Our fighters again intercepted and destroyed many enemy aircraft.
During the period of these attacks on the South East Coast, two patrols of about 20 aircraft each were maintained by the enemy in the Straits about 10 miles south of Dover.
Portsmouth Area
Shortly after 0930 hours, one raid unsuccessfully attacked an RAF establishment at Poling.
At 1151 hours, a raid of 150+ aircraft was plotted 30 miles north of Cherbourg. This raid split into a number of smaller raids which approached on a wide front. Some reached Portsmouth and Southampton where damage was done. Others flew over convoys off the Isle of Wight but no damage to shipping is reported. An RAF establishment at Ventnor was bombed and damaged at about 1300 hours.
In the above raids the enemy were engaged by our fighters and suffered further losses.
Reconnaissances
There have been a number of reconnaissances searching for shipping off the East Coast. The was one reconnaissance from Shoreham up to Northolt and one over South Wales and Somerset and it is reported that one aircraft flew over the north of Scotland to 250 miles out into the Atlantic thence down the West Coast of Ireland.
By night
Widespread raids in small numbers occurred over the country. Minelaying was suspected off the North East and East Coasts and in the Thames Estuary and Bristol Channel. Enemy aircraft were active near Bircham Newton, towards Nottingham and in the Blackpool district. About 6 raids approached Norwich but did not appear to penetrate far inland.
