Oblt. Friedrich Kohlweiss shot in Troyes on the 27. July 1944

Hallo!

My Name is Andreas Kohlweiss!
I am from the City Graz in Austria

My Uncle 3rd grade was Oberleutnant Friedrich Kohlweiss.
He was a Luftwaffe Pilot with many flights in different Airplane types, like de He 111, the Me 110 and in his last days the Bf 109.

I am writting a short story about his Life and because of this i am searching for further informations about his dead.

He was shot in Romilly near Troyes (France) in the west front war on the 27th of July 1944.
The Unit I./JG 27 flies from Varades to Champfleury, where the unit get in trouble with american fighters/hunters. Then in a short air combat he was shot by an american hunter, but i have no information, which airplane or which pilot his fighting enemy was.

Maybe there is a specialist there in the forum which is able to help me to find out the name of the american pilot or at least the Airplane type. This would be great.

I have some further informations:
On this day he flies a Messerschmitt Bf 109 with the Production number 165658.

I am looking forward to hear from you,

Best regards and thank you,

Andreas Kohlweiss
