Enemy action by day
With the exception of attacks on Filton and Portland during the morning and an attack on Plymouth in the afternoon enemy activity has been confined to small raids chiefly in the South Eastern area. About one hundred aircraft had massed in the Calais area by 0900 hours but an attack did not materialise.
During the day our fighters destroyed twenty-two enemy aircraft (plus eight probables and ten damaged). In addition anti aircraft destroyed three enemy aircraft (plus two damaged). Our losses were four aircraft with one pilot missing and one died of wounds.
In the main attacks, the proportion of fighters to bombers appears to have been approximately equal.
Attack on Filton
At 1148 hours, about sixty enemy aircraft consisting of twenty seven bombers with fighter escort, which had crossed the coast near Weymouth, attacked the Bristol Aeroplane Company's Works at Filton. The attack was made from 11,000 feet and all bombs were dropped simultaneously. Three Squadrons plus one section were despatched to intercept and all of them engaged, though only one Squadron succeeded in doing so before the enemy aircraft reached the target. Eighteen enemy aircraft - chiefly bombers - were destroyed (plus six probables and seven damaged). Anti aircraft destroyed three enemy (plus two damaged). Our losses were four aircraft and one pilot (died of wounds).
Attack on Portland
It is reported by AA Command that seven Ju88s broke away from the main body flying to Filton, and made an unsuccessful dive bombing attack down to 500 feet on the oil tanks at Portland.
Attack on Plymouth
Approximately twenty-four enemy bombers with an escort of twelve Me110s crossed the coast at Start Point and attacked the Plymouth area at 1647 hours. Two sections of fighters intercepted and dispersed this formation. One enemy bomber was destroyed (plus two aircraft probably destroyed and one damaged) without loss to our fighters.
Reconnaissances and Patrols
Hostile reconnaissances - mostly of single aircraft - were plotted during the day as follows:
- Over three convoys - one of which is reported to have been attacked.
- London (three), Thames Estuary, Luton, Hatfield, Farnborough, Northolt, Kent, Sussex Coast, Bristol Channel, Somerset, Wiltshire, Hampshire and east of Yarmouth. Patrols by enemy aircraft were frequent in the Straits.
Night Operations - 25th/26th September 1940
Enemy activity in the London area was widespread and steadily maintained throughout the night.
1930 to 2100 Hours
Shortly after 1930 hours, raids began doming out of Le Havre towards Portsmouth and made for London. These were followed by others from Cherbourg which entered along the coast Westward from Beachy Head. Other raids from Holland came in over the Norfolk Coast and the Wash. Some of the later made a wide sweep and approached London from the North West.
During this period, about twenty-five raids crossed our Coast, some of which flew to South Wales and one over Derby.
Anti-aircraft in the Rochford area claim to have destroyed on JU88 at 1940 hours which is reported to have fallen into the sea.
2100 to 0100 Hours
About 100 enemy aircraft came inland, nineteen of which proceeded to the Midlands (as far North as the Mersey) and to the West Country and South Wales.
After 2300 hours, raids ceased to approach London from East Anglia, the points of entry being between Dungeness and the Isle of Wight. Many raids appeared to return via the Estuary to the Dutch Coast.
After midnight, about nine aircraft from the Dutch Coast circled in the outer Thames Estuary and may have been engaged on a shipping search or minelaying operations.
0100 to 0500 Hours
At 0115 hours, a new series of about twenty raids started approaching from Holland and made for the London Area, but some remained in the Thames Estuary and these, to, may have been minelaying.
By 0530 hours, the last raids from the London area had recrossed the South Coast.
In addition to the activity mentioned above, there have been a few raids in Lincolnshire, the Humber area and in the South West. There has been no activity in the North of England or in Scotland.
