Monday the 9th of September 1940

Day: No attacks appeared until the afternoon, when massed high-flying groups are broken up approaching Thames Estuary. This resulted in much scattered bombing - much of it jettisoned rather than aimed over a wide area of Kent and Surrey. Some bombs were dropped on Central London. 412 civilians are killed, fifty of them in one block of flats. Every railway line to the South of London were blocked. Raids aimed at London are beaten back.

Beaufighter's equipped with A1 radar enter service.

Night: Wave technique also applied at night, in continuous attack on London by Air Fleet III, including the City of London and the West End.

Losses: Luftwaffe 28: Fighter Command 16.

Weather: Fair, but cloud, scattered showers and thunder in east.
