Friedrich was shot down on Apr.17/43 near Hochspeyer by an RAF bomber he was attacking. There are two likely candidates.
Just after midnight Halifax HR758 was engaged in a combat that began over Borrstadt continued to Gollheim and was finally shot down 2 miles north of Borrstadt. They are believed to have shot down their attacker.
At 1 am Stirling BK659 was 15 miles west of Mannheim on a track for Hochspeyer when it engaged a two engine German fighter and they believed they shot it down after seeing an explosion in the air and on the ground 30 seconds later.
I believe the records only show one German loss in the area that night.
Is there any way of determining what time Friedrich was shot down?
Also can anyone confirm that Friedrich was was wounded as well as his Bordfunker?
Thanks
