With fine weather, the Germans tried out their new tactics. Numerous coastal radar installations were bombed but most were repaired and operational by the end of the day, although Ventnor (Isle of Wight) was badly damaged and still be out of action. The Luftwaffe mounted heavy raids on British airfields in Kent (Manston, Lympne & Hawkinge). Portsmouth was also bombed, leaving 100 civilians dead. To test the effects of knocking out radar, the Germans also attacked convoys in the English Channel and Thames Estuary, sinking the minesweeping trawlers HMT Pyrope and Tamarisk. Despite damage to radar and runways, the RAF responded to most of the attacks and shot down 55 German aircraft for the loss of 6 Spitfires and 9 Hurricanes. The Lutfwaffe lost 7 more bombers to anti-aircraft fire.
