Aug 14
     On the afternoon readiness were: F/Lt Szczesniewski, F/O Falkowski, F/O Czajkowski, F/O Nowak, P/O Gil, P/O Andersz, P/O Drybanski, P/O Grudzinski, Sgt Chudek, Sgt Krieger, Sgt Gruszczynski and Sgt Cwynar.
Around 3:00 p.m. W/Cdr Rolski called pilots to the briefing room. Present was a station commander: G/C McEvoy. Rolski announced fighter sweep on route: Northolt - Hardelot - Fruges - Saint Omer - Dover - Northolt. He was to lead Sqr. 3006, S/Ldr Pisarek Sqr. 308 and F/Lt Szczesniewski Sqr.315. The altitudes were given for each squadron. 306 Squadron would fly at 21,00 feet, 308 at 24,000 and 315 at 27,000. The objective was to engage German fighters so the six Blenheim bombers - flying several minutes after - would have easier time over the munitions factory in Marquise. The weather outlook was described. Pilots made notes and received escape packets.
Squadron 315 took off at 8 a.m. and after 20 min passed near Calais. Then "zulu" called "carmen" leader announcing about 30 bandits left at 22K. All 36 pilots heard this message and all of them instantly started to look for e/a. After about three minutes, F/Lt Szczesniewski went on the R/T:
- Carmen leader, this is brickbat leader. I see them lower left, about thirty a/c.
W/Cdr Rolski replied:
- I see them too. Mary leader and brickbatt leader, attack.
Both squadrons maneuvered to get the suns in their back and almost simultaneously tore down on the e/a. Germans appeared to be surprised. After the first attack of the polish Spitfires few Bf-109s went down trailing smoke. First white umbrellas of parachutes appeared. A wild mêlée broke out, where everyone was on his own.
306 Squadron, led by W/Cdr Rolski,  stayed out of the fight. Few minutes later they went after 12 Bf-109s that were going down to join slowly descending fight, and clashed with them.
After the battle pilots of Polish Wing returned to Northolt alone or in small groups.
315's intelligence officer: F/O Harding received reports and it became obvious that his squadron had a great day.
    F/Lt Szczesniewski 1 Bf-109 destroyed and 1 Bf-109 probable.
    P/O Grudzinski ......2 Bf-109 destroyed
    Sgt  Chudek ...........1 Bf-109 destroyed and 1 Bf-109 damaged
    F/O Falkowski ......1 Bf-109 destroyed
    P/O Gil .................1 Bf-109 destroyed
    Sgt  Krieger ...........1 Bf109 destroyed
    Sgt  Cwynar ...........1 Bf-109 destroyed

     F/O Falkowski recalls: That was a Wing operation. Three squadrons were to operate together: 306 at 28,000 feet, 315 in the middle at 27K and 308 at 27K. We took off few minutes after 8 a.m., and after 20 min we crossed a French coast. In the same time, few other squadrons were escorting bombers on their way to target area. We were flying south of Calais when I spotted a group of about thirty German aircraft. They were some 17K below us. "Petro" (S/Ldr Pietraszkiewicz) gave the order to attack. We had a total advantage. Enemy was below and the sun was behind us. Moments after we started to dive somebody from the 306 Squadron called out another group of Messerschmidts. They started their own fracas what gave us a secure back. The situation was developing in a favorable way. Our two squadrons swooped down on the lower group of e/a. There was 24 of us against 30 Bf-109s and felt very confident. I selected one Messerschmidt and pressed the tit. I was shooting till its empennage came off. Then I saw a thick trail of a smoke coming out of it and e/a went down. Disposing of "my" German I looked for the rest of the squadron to join them. Doing this I saw how Sgt Malczewski and "Petro" trashed theirs Bf-109s. It was a very interesting scene. "Z wiatrem w twarz" Jan Falkowski.
