Thursday the 15th of August 1940

Day: All three Luftflotten were in action in a maximum effort against airfields, radar stations and factories, including a heavy attack by seventy two He111's of KG 26 and twenty one Bf 110's of ZG 76 (Luftflotte 5) on the Newcastle area. They were intercepted by No 72 Squadron from Aklington. RAF Driffield was bombed and 10 Whitley bombers were destroyed on ground. Other attacks left Dishforth, Linton-on-Ouse and Usworth undamaged. Bridlington ammunition dump was blown up. In the South, factories at Rochester (Short Brothers and Pobjoy) and Croydon (Rollason and Redwing) were severely damaged. Hawkinge and Lympne airfields were badly damaged, the latter put out of action for about 48 hours. Other airfield targets include Manston, Martlesham Heath, Middle Wallop and West Malling. Croydon town was bombed in the first attack on London. Raids on Eastchurch spread into Kent, Surrey, Hampshire, Wiltshire, and the Isle of Wight, engaging 11 Group Fighter Command Squadrons. Today saw the most widespread activity of the battle.
There were 1,786 German sorties in 24 hours.
Fighter Command flew 974 sorties
Night: Widespread night raiding across entire central England from Swansea to the Wash.

Comment: This day is a turning point. German losses convince the Luftwaffe that air superiority is essential before all-out bombing can be successful. It also marks the virtual end of Luftflotte 5's offensive usefulness, so sparing the North such heavy attacks in future. It also marks the beginning of the end of the Ju 87's usefulness as a dive bomber and that of the Bf 110 as an escort fighter.
Losses: Luftwaffe 71: Fighter Command  34.

Weather: Fine and warm anticyclonic weather.
