LW involvement in Air Battle on Sept. 13, 1944
 

HI All.

I am looking for losses of Luftwaffe suffered over Poland on September 13, 1944. Two 31.FG pilots claimed one Me 109 and one FW 190. I know few JG 52 a/c were involved...but any other units? (JGr Ost?)
Can someone provide me with losses of Luftwaffe a/c in the area of poland, northern Czech or northern Slovakia on that day?
Thanks a lot! This woould solve some mysteries...
