Fine weather gives the opportunity of the first really big raids on British airfields. German bombers and fighters from Norway and Denmark crossed the North Sea to bomb RAF airfields in the North of Britain. At noon, they were met by RAF fighters. Simultaneously, a formation of 1,100 Luftwaffe aircraft crossed the Dover Straits, then split up heading for various airfields. RAF squadrons were scrambled, giving rise to dogfights over Kent and the English Channel. Numerous airfields received damage to aircraft, hangars and runways. Radar stations at Rye, Dover and at Foreness were put out of action. In the evening Messerschmitt Bf110s bombed South London airfield (now known as Heathrow Airport) by mistake. Many Bf110’s were shot down by RAF fighters, crashing in the London suburb of Croydon.
Despite taking a heavy toll on RAF installations, the Luftwaffe lost 161 aircraft, mostly bombers, while RAF losses were 34 fighters, but only 18 pilots. Other sources quote 76 German losses and 35 British.
In British Somaliland the Italians again attacked British defences at Tug Argan and took another hill. British forces withdrew overnight towards Berbera. The Black Watch along with African and Indian troops held a rear-guard position ten miles back at Barkasan on the Berbera road.
Italy attacked the neutral Greek Navy near the tiny Aegean islands of Tinos and Syros. The Italian air force bombed the Greek destroyers Vasilissa Olga and Vasilevs Georgios I escorting merchant ships, and the Italian submarine Delfino sank the Greek cruiser Helle at anchor.
The Kriegsmarine ordered construction of 86 new U-boats. UA sank the Greek steamer Aspasia, carrying Manganese ore, with two torpedoes 700 miles West of Gibraltar. All 19 crew were killed in the explosion and subsequent fire.
U-51 sank the British tanker Sylvafield, carrying 7,860 tons of fuel oil, 190 miles Northwest of Rockall, Ireland.
The U.S. Army contracted with Chrysler to build the Detroit Arsenal Tank Plant in Warren, Michigan.
Game day 350. Japan
Japan deployed two new fighter units and two destroyers in the home islands, as well as two infantry and two armoured units in Manchukuo.
Infantry units continued to move eastwards in China and SingKiang. Six armoured units disembarked in Shanghai. Six more moved west from Kwangtung into China to support two infantry units in attacking three Chinese infantry units. The Chinese were wiped out for the loss of one Japanese armoured units.
These were the last Chinese military units in China, so the territory became Japanese-controlled.
