Battle of Britain Campaign
Diary
Date: 21st September 1940
- Weather: Mainly fine.
- Day: Some fighter sweeps in east Kent.
- Night: London and Merseyside attacked.
Enemy action by day
Enemy reconnaissances were active along the East, South and South
West Coasts during the day and attacked some isolated objectives.
In the evening a strong formation, consisting mainly of fighters,
made a sweep over Kent and the Estuary, some penetrating to the eastern
boundary of Central London. During the day our fighters destroyed
2 enemy aircraft (plus 1 probable plus 6 damaged). Our casualties
were nil.
Major Attack
Between 1750 and 1800 hours seven formations crossed the coast between
Dungeness and North Foreland, flying North West. These were followed
by others until about 200 enemy aircraft in all were over the country.
Twenty Squadrons were sent up, while others patrolled Hornchurch,
North Weald, and Guildford. Combats do not appear to have been numerous
and only one enemy aircraft is reported damaged.
North and East
Reconnaissance aircraft were reported off North East Scotland in
the Castletown area, 20 miles South of Scapa, and East of Flamborough
Head. In the afternoon the Royal Air Force Station at Waltham was
attacked and suffered minor damage.
South East
At 0823 hours enemy aircraft attacked Weybridge and one of these
is believed damaged. Later targets near Ramsgate and Rye were unsuccessfully
attacked. Reconnaissance aircraft flew over the Hastings, Dungeness,
Redhill and Tonbridge areas during the day. Attempts to intercept
did not succeed.
South and West
Hostile aircraft reconnoitred Thorney Island, Tangmere, Kenley,
Middle Wallop, Spithead and districts in South Wales. Of these two
were destroyed, one near Tangmere and one in South Wales (plus one
probable and four damaged).
By night
London Central received a RED warning at 2009 hours. A steady stream
of enemy aircraft came from Holland and Le Havre. Those from Holland
crossed the coast between Thames Orfordness and went to London from
the North; those from Le Havre crossed the coast near Shoreham and
went to London and then returned to the South. Later hostile raids
continued to come from the direction of the Belgian Coast and later
still from the direction of Le Havre and Dieppe entering between
Beachy Head and Dungeness and covering South London, Biggin Hill
and Kenley districts.
On the whole, it would seem that the enemy activity was not quite
so intense as of late.
Just after dust East Anglia received a good deal of attention and
some of the raiders flew down to the London area. Many enemy aircraft
flew over the Bristol Channel and up over Wales to Liverpool which
was given more notice than for some time past.
Minelaying was suspected in the Estuary also off the North-East
coast of Yorkshire, in the Tyne area, possibly off the Firth of Forth
and off the entrance to Stranraer. Raiders also visited the Lancashire
Coast, North of the Tyne and the Midlands near Derby and Sheffield,
and two raids were plotted off the Scottish Coast South of Aberdeen.
Four or five raids flew over two convoys North of the Tyne and it
is reported that two aerial torpedoes were dropped.

- Date: 21th September 1940
- During the day Surrey, Sussex, Kent, Essex and the
East End of London were indiscriminately bombed, but
very little damage was done and few casualties reported.
- After dark London was again attacked and bombing seems
to have been chiefly directed against the East End and
the Dock areas where very serious fires have resulted.
- Liverpool and adjoining areas were also the scenes
of bombing resulting in several fires.

Cut and also damaged part of a warehouse. Navigation
is therefore closed from the Thames to Britannia Bridge.
