Fighter Squadrons intercepted and casualties were inflicted on the enemy.
At dusk, 25 enemy aircraft, originating from the Bay of Biscay, attacked Crewe.
Reconnaissances by small formations and single aircraft were made along the South Coast and inland, increasing in intensity particularly between 1600 and 1700 hours.

Intense activity took place off the Dutch Coast.
South East Coast
Reconnaissances in the Estuary and over East Kent were made during the morning and 4 aircraft operating singly, penetrated to London.
Great activity prevailed in the Straits and off the French Coast.
During the afternoon, activity increased and coastal towns were bombed by single aircraft. Landfalls were made at Harwich and Hastings, the aircraft in the former case penetrating to London via Debden and Northolt and departing via Kenley and Biggin Hill.
Interceptions were attempted without conclusive results.
South and West Coasts
Between 1500 and 1700 hours, reconnaissances were made from Selsey Bill to Cornwall.
At 1630 hours, about 40 enemy aircraft approached the Isle of Wight from Cherbourg and these were followed by a second wave of bombers and fighters amounting to about 60 aircraft.
At the same time, single aircraft approached Beachy Head possibly as a diversion. The objective was Southampton where the Supermarine Works were extensively damaged. Dive-bombing as well as high-level bombing is reported. 12 Squadrons were in the air of which 8 were engaged in the defence of Southampton. No interception was made prior to the attack. 31 enemy aircraft were destroyed (plus 10 probable and 10 damaged) as a result of combats during this attack with a loss of 8 of our aircraft (plus one probable and 2 damaged).
At about 1800 hours, a reconnaissance by 3 aircraft was made over Southampton and Middle Wallop, while a further 3 aircraft came in at Christchurch.
Midlands
At 1950 hours, 23 enemy aircraft attacked Crewe having flown from the Bay of Biscay up the Irish Sea and across Wales. After leaving Crewe, the raids split up and returned via Bristol and Poole Bay.
Night Operations - 26th/27th September 1940
Enemy activity was first widespread over the whole country South of a line Liverpool to Humber. Raids did not approach London until 2030 hours and then continued until 0300 hours. A lull until 0500 hours followed when 12 further raids visited London.
1930 to 2100 Hours
40 raids crossed our Coasts originating from the Dutch Coast, Le Havre and Cherbourg and entering between Cromer-Humber, Beachy Head - Selsey and Selsey - Swanage, respectively. Many of the raids from the Dutch Coast flew due West to the Midlands. At 1950 hours, a convoy in the Firth of Forth reported that it was being attacked.
2100 to 0100 Hours
Hostile activity was continuous and was concentrated on the London area although some raids visited Liverpool, the Midlands, Cambridge, Mildenhall, Newmarket and Duxford, and enemy aircraft from Cherbourg flew coastwise from Lyme Bay to Start Point.
There was suspected minelaying in the Thames Estuary and off North Foreland.
0100 to 0600 Hours
Enemy raids originating from Dieppe and proceeding to the London area, mostly entered between Beachy Head and Folkestone. One raid entering at the Wash, penetrated inland to Digby and flew back over King's Lynn.
There was a lull from 0300 to 0500 hours and the Country was entirely clear for 1 hour, when about 12 raids - some of which were at first thought to be returning friendly bombers - came out of Dieppe and were plotted to London. These were all homing by 0450 hours and the Country was again clear by 0600 hours.
