There were two major attacks on London and the southeast on 5 September 1940, consisting of Do17s, He111s, Ju88s, and Me109 escorts, the first between 09:40-10:40, and the second between 14:15 and 16:30.

I've checked the 11 Group ORB, 11 Group Appendix, Hornchurch ORB, and 41 Squadron ORB, but none of these docs seem to identify the estimated size of the attacks, i.e. how many Luftwaffe aircraft were involved.

Can anyone point me in the direction of a source, or quote me details from a reputable source, that identifies how many bombers and fighters were involved in these attacks, please? I'm not seeking detailed breakdowns, rather top level estimates (or actuals, if available) on the numbers involved.
