Yes. I am tracing my grandfathers path through France and Germany with the 80th Infantry Division and his battalions AARs say they were strafed both days by Luftwaffe fighters. The Battalions AAA claimed they saw hits/damage but none shot down. Was hoping to see what Luftwaffe units they were.
I see. Those sorts of late war Luftwaffe diaries are extremely rare. However, I can tell you that II/JG 3 and III/JG 76 were based outside of Châlons-en-Champagne until the Allies captured it around the same day you mention. The airfield in question was officially captured by the Allies on September 4.
Uncertain on the JG 3 claim, actually.
