Shortly after 0700 hours, ten Ju 87 Stuka dive-bombers from IV/LG 1, escorted by Bf 109s from III/JG 27, headed towards a convoy passing through Lympne Bay. Three Hurricanes of No. 501 Squadron were en route to intercept the Stukas when they were bounced by the Messerschmitt escort, losing one aircraft. Six Spitfires of No. 609 Squadron were scrambled from Warmwell and arrived over the convoy just as the Stukas attacked. Outnumbered by odds of 6:1, the squadron was routed and lost two aircraft. However, none of the ships in the convoy were hit.
At 1100 hours, another formation of Ju 87 Stukas from StG 2, escorted by Bf 110s from III/ZG 76, was despatched to attack the convoy. Eighteen Hurricanes from Nos. 87, 238, 501, and 601 Squadrons were scrambled and met the enemy aircraft over Portland. Four Bf 110s and two Ju 87s were shot down. Another Ju 87 was damaged and force-landed at St-Inglevert. The 530-ton patrol vessel HMS Warrior II was sunk.
At 1715 hours, twelve He 111 bombers from KG 51 and KG 55, escorted by twelve Bf 110s from III/ZG 76, appeared heading for Portsmouth. Hurricanes from Nos. 601 and 145 Squadrons intercepted and shot down three bombers. Two Hurricanes were also lost including one that was hit by “friendly” AA fire. A number of He 111s evaded RAF fighters and bombed Portsmouth dockyard, sinking three barges and damaging the French destroyer Savorgnam De Brazza. Bombs also fell on the city, killing 19 civilians and injuring 26.
