Astonishing! Again chaps thanks for this. The Thesis seems to indicate that on 3.6.30 the groupe claimed one He111 with two others probably destroyed and an Me109 possibly destroyed.
Previous posts change the dates for many claims with the 18th June victory being relocated to 9.6.40, and total claims for 8.6.40 now being 5 confirmed instead of one destroyed or probable.
The one thing that the all agree on is that the groupe were officially (?) credited with 15 victories. Either 12 or 13 destroyed and 2 or 3 probable.
this is an interesting account of the 8.6.40 scrap...
At 3:54 p.m., a section of five aircraft, led by kpt. Wczelik, took off to patrol over the Vernon-Meulan area. South of Rouen, the Poles attacked a group of about twenty Messerschmit 110s and had a good scrap with them. They landed at 5:10 p.m. Officers Wczelik and Czerwinski claimed victories, but none of the other pilots saw the enemy aircraft crash. Commander Kepinski recognized only one of them as probable but soon after, around the area of that clash, the wrecks of five Me-110s were found. After a fight analysis, por. Tadeusz Czerwinski was credited with two enemy aircraft shot down, while kpt. Wczelik, ppor. Aleksy Zukowski, and ppor. Jerzy Godlewski with kpr. Piotr Zaniewski were credited with one Bf110 each
