September 4th, 1940
UNITED KINGDOM:
RAF Bomber Command:
4 Group (Whitley).51 Sqn. 1 aircraft missing from Berlin, ditched off Holland. 1 crew drowned, rest PoW.
Bombing - power station at Berlin - oil tanks at Magdeburg - ‘Razzling’.
51 Sqn. Six aircraft to Berlin. Five bombed and ‘Razzled’, one FTR.
78 Sqn. Six aircraft to Magdeburg. Five bombed primary, one bombed Bremen.
Battle of Britain:
RAF Fighter Command: Airfields at Bradwell, Lympne and Eastchurch (twice) are bombed.
Medway towns and Shorts aircraft factory at Rochester and Vickers at Weybridge are bombed.
At night Liverpool, Bristol, south-east England are raided.
A small group of low-flying, bomb-carrying Bf110s of ZG 76 crossed the coast at Littlehampton, then made for Brooklands Hurricane factory. Hurricanes of 253 Squadron patrolling near Guildford and using Observer Corps information swooped upon the ‘110s, destroying six. Confusion overtook the remainder as they hurled 500-kg bombs at the Vickers Wellington factory, killing 88 and causing over 700 casualties as a result of heavy machinery, materials and glass being hurled around factory shops.
The intention was that Bf110s and ‘109s of Erpro 210 after attacking Poling CH (Chain Home radar) station, would provide withdrawal cover for ZG 76. Instead, RAF fighters also dealt effectively with the escort, picking off its Gruppenkommandeur and forcing ZG 76 to find its own way home.
Losses: Luftwaffe, 25; RAF, 17.

Day 370 September 4, 1940
Battle of Britain Day 57. More good weather for flying and Luftwaffe sends 2 raids up the Thames Estuary and across Kent to attack RAF airfields at Brooklands, Eastchurch, Lympne & Rochford as well as the aircraft works at Rochester (Short Brothers) and Brooklands (Vickers Armstrong, where 55 workers are killed and 250 injured). 20 German aircraft are shot down (6 Bf109s, 1 He111 and 13 Bf110s). RAF loses 9 Spitfires, 6 Hurricanes and 1 Defiant which crashes during night landing practice (11 pilots and 1 gunner killed). Overnight, there is bombing of South Wales and the Midlands. Hitler makes a speech condemning RAF bombing of Germany and threatens the destruction of British cities in retaliation. This is exactly the reaction Churchill is hoping for, to draw the Luftwaffe’s fire away from the RAF airfields. http://www.battleofbritain1940.net/0034.html

Wasn't Grayling to be the standard design for attack submarines in the USN for the next few years?
