Friday 23 August 1940
|Heinkel He 115 seaplane.|
A Luftwaffe raid on RAF Manston at 13:25 and Thorney Island around the same time. There are several other attempted penetrations that either can't find their targets in the clouds or abort their missions before they even reach the coast.
After dark, the Luftwaffe once again attacks the Bristol and South Wales sector, with Cardiff and RAF Filton taking damage. There are solo raids all along the coast up to York, with a raid on Aberdeen as well.
Heinkel He 115 seaplanes of Küstenfliegergruppe (KGr) 506 (based at Stavanger, Norway) torpedo and sink 5035 ton British cargo ship Llanishen in the Moray Firth and 6680 ton Makalla in the Pentland Firth. There are eight deaths on the Llanishen. Both the Llanishen and Makalla have been travelling with Convoy OA 203. This is a change in tactics by the seaplanes, which heretofore have been dropping bombs to little purpose. Using torpedoes seems to be a much more effective plan. Heinkel He 115 seaplanes are the largest in action during the war (as opposed to flying boats, which are much larger).
The Luftwaffe bombs and sinks ferry HMS New Royal Sovereign at Bridlington, Yorkshire. There are no casualties as nobody was aboard.
Kriegsmarine trawler No. 13 "Düsseldorf" hits a mine off Dieppe and is beached where it can be salvaged.
During the day, the RAF raids the big German coastal guns at Cap Gris Nez again, without success. After dark, there are scattered raids by Bomber Command against airfields, railway installations at Mannheim and the Ruhr industrial valley.
The Luftwaffe drops mines in the Thames estuary and outside ports along the eastern coast. RAF Bomber Command also sends 40 planes on mine-laying missions.
Friendly fire incidents continue to bedevil the RAF. Anti-aircraft fire downs a Hurricane of RAF No. 73 Squadron operating out of Church Fenton. It crashes west of Beverley, Yorkshire at 01:30, but the pilot bails out safely. Another Hurricane force-lands at Withyham, Kent after running out of petrol, and that pilot is ok as well.
The score for the day shows minimal losses for both sides, between 1-5 planes for both sides. Exactly how many planes each side loses depends on whether or not you count things like the friendly fire incidents, planes lost on the ground and so forth, and when you don't count those, the RAF figures tend to improve substantially.
Pilot Officer Petrus Hendrik Hugo, of RAF No. 615 Squadron is awarded the DFC for downing five Luftwaffe planes in June and July.
RAF No. 304 (Polish) Squadron forms at RAF Bramcote. This takes the name "Land of Silesia" and is led by Wing Commander William Graham.
RAF No. 307 (Polish) Squadron forms to fly night fighters.
RCAF No. 1 Squadron is operational and sorties against some Luftwaffe planes today, but has no victories or losses.
Reichsmarschall Goering continues his purge in the Luftwaffe fighter units (so far, other units have been spared):
- Walter Oesau replaces Trautloft as Gruppenkommandeur of III./JG 51;
U-37 also sinks 1,718-ton Norwegian freighter Keret in the same convoy. Some sources place this sinking on the 22nd, others on the 23rd. There are 10 survivors and 33 crew perish.
Battle of the Mediterranean: British destroyer HMS Hostile hits a mine at 03:17 and eventually sinks (torpedoed by HMS Hero to avoid it falling into Italian hands) in the Strait of Sicily off Cape Bon. This is where the Italians recently laid a minefield. There are 141 survivors and five crew perish.
The Italians cautiously return to Fort Capuzzo, which they evacuated after a recent Royal Navy attack.
Admiral Cunningham in Alexandria has a flotilla led by the Australian cruiser HMAS Sydney attack the Italian seaplane base at Bomba, Libya.

US Military: Cruisers USS Wichita and Quincy continue their "Show the flag" cruise along South America and make port in Montevideo, Uruguay. Meanwhile, destroyers USS Wake and Wainwright depart Pará, Brazil for the Guantanamo Bay Naval Base.
Destroyer USS Allen (DD-66) is recommissioned (originally commissioned on 24 January 1917) as part of the Pacific fleet now based at Pearl Harbor. It is the oldest destroyer in the fleet.
British Government: British Prime Minister Churchill officially changes the name of the local volunteer defense forces to Home Guard. The Home Guard now (finally) is receiving uniforms, weapons, ammunition, and some training to make it a somewhat more professional force.
King George VI issues a proclamation striking all Italians and Germans from the lists of British titles and decorations. This deprives Italian Duce Benito Mussolini and King Victor Emmanuel II of decorations.
Greece: The Greek army, alarmed by recent Italian provocations such as the sinking of the light cruiser Helle, takes anti-invasion precautions.
American Homefront: Shirley Temple's final film for 20th Century Fox, "Young People," premieres at the Roxy in New York City.
