Official start of the Battle of Britain

The Air Ministry classifies the Battle of Britain as being between 10 July and 31 October 1940.

Pilots and aircrew who flew at least one sortie with a squadron under the operation control of Fighter Command were deemed to have taken part in the battle.

Germans attack southern England with a formation of 70 aircraft.

EprGr 210 attack four radar stations

Visibility is perfect with Dungeness being visible from Dover.

The Bf 110s of EprGr 210 lead by Swiss born Hptm Rübensdörffer come in at low level to attack the radar network. Lacking azimuth tracking and confusing range information by passing abeam the radar sites, the Filter Room at Fighter Command assigns the plot an 'X' code (doubtful origin).

Oberleutnant Otto Hintze leads 3 Staffel's eight Bf 109E-1/B Jabos - carrying one SC250 bomb each - attacking Dover. They approach the Dover radar at right angles to make them harder to detect but are picked up by the Rye Radar. The towers are slightly damaged and huts are smashed. Hintze reports seeing the towers clearly swaying.

Two minutes later Lieutenant Rössinger leads 2 Staffel's Bf 110s attacking Rye. Almost every building is hit, except the transmitting and receiving block. The Filter Room repeatedly tries to contact them eventually being told by a WAFF that "Your X raid is bombing us."

Hauptman Rübensdörffer leads the attack on Dunkirk. One 500kg bomb moves the concrete transmitter building several inches.

The final element of 1 Staffel's Bf 110s hit Pevensy with eight 500kg bombs, one of which cuts the power line taking the station off line.

A breach of 160 km has been opened in the radar coverage.
