Led by S/Ldr Janus; squadron took off at 11:00 a.m. Its mission was to form a top cover for a Wing, which was escorting squadron of "Hurrybombers". "Deblinski " flew at 10K and ~5 miles from French coast. After few minutes of patrolling, F/Lt Czajkowski observed and called out three Bf-109s sneaking-up on his section. He attacked them with his wingman Sgt Czezowski. E/a started down with Polish Spitfires on their tails. They were nose-diving down to 3K. F/Lt Czajkowski got one Bf-109 at that level and sent it crashing to the sea. Meantime, S/Ldr Janus trounced another one. Air became full of individual duels for few minutes. One Bf-109 got F/Lt Groszewski only to be damaged by P/O Kornacki in return. F/Lt Groszewski jumped out landed in the sea. He was O.K. seating in his dinghy while P/O Kornicki's section hung around. Section from British squadron stationing in Biggin Hill changed Poles, but did not find floating pilot. Rescue boats got under attack of German fighters while approaching the area. Thus, for a price of one of its pilots, 315 destroyed two and damaged one Bf-109s.
