Battle of Britain Day 27. Despite fine weather, it is another quiet day. Large Luftwaffe formations patrol the Dover Straits and attack convoys off the East and Southeast coast of England. RAF fighters go up to intercept (4 Messerschmitt Bf109s and 1 Spitfire are shot down). Several other raids approach the coast and convoys but turn back before engaging. There is little activity overnight, with some minelaying. The number of serviceable British fighters has increased by 55 in the last 2 days.
British Somaliland. Italians take the port of Zeila on the coast near the border with French Somaliland, effectively isolating the British colonial forces and advance on Berbera from the West. The main Italian force, going across the mountains towards Berbera, is held up at Hargeisa. Italian light tanks push back Somaliland Camel Corps and other unarmoured British units.
