Date: 9th September 1940

Enemy action by day
One main attack was made in the afternoon by some 300 aircraft in direction of Thames Estuary/South London and Biggin Hill but only a section penetrated to Central London. During the resulting engagements our fighters destroyed 50 enemy aircraft (plus 9 probable and 13 damaged) and Anti-Aircraft fire accounted for 2 destroyed and 2 probable. Our casualties amounted to 20 aircraft of which 5 pilots killed or missing.
There were also a number of enemy reconnaissances, mostly over Convoys on East Coast.
East
One raid is reported to have made an early morning attack on a Trawler, 25 miles East of Lowestoft. Four raids made a reconnaissance of convoys off East Anglian Coast, of which one also penetrated to Bury St Edmunds. Two raids crossed Lincolnshire Coast. Interception was made by without success.
South East
One early raid to Clacton and another from Beachy Head to Central London and back over Hastings. Later in the morning a raid of three aircraft approached the Kent coast. Fighters unsuccessfully attempted interception. Apart from patrols in Calais/Boulogne area, there was little enemy activity until 1605 hours when formations began to mass in Calais/Boulogne area. From 1655 hours an attack in force on the South East crossed the Coast between North Foreland and Cover. Enemy strength is estimated at some 300 aircraft amongst which there are reported to have been 6 four-engined aircraft with strong fighter escort. Up to 1730 hours the main trend was towards the Estuary and South London, though one raid of about 35 aircraft penetrated to Central London.
A general drift Westwards then developed, and small raids were plotted as far West as Salisbury. The enemy withdrew in small groups and during this period Dover was shelled. 24 Squadrons of fighters were detailed to this attack, inflicting heavy casualties, and an intercepted instruction from Gruppe Headquarters read "Break off task if fighter opposition is too strong". Later it was reported that shipping off Dover was attacked by enemy seaplanes with fighter escort.
By night
The usual stream of raids started to come out of Cherbourg and the Somme about 2000 hours, crossing the coast between Isle of Wight and Dungeness, all proceeding to the London area, where again four to five raids were maintained for most of the period.
From about 0230 hours the method of approach changed and activity increased. Raids had by this time practically ceased to come out of French Coast and were replaced by a larger series of raids from the Dutch Islands via the Thames Estuary into the London area, homing over Dungeness.
Soon after 0430 hours the last raids were leaving the London Area and by 0455 hours the country was clear of enemy raids.
There were a few raids before midnight in South Wales, Bristol, Midlands and one to Liverpool, and later raids spread up the East Coast with a few penetrations inland. Minelaying was suspected between Newcastle and Middlesborough.
Dover was reported to have been shelled several times during the night.
