Ok this is way out of left field.
Just got some info from Germany. My great uncle died at 0400 on 17 July 1941 on the railway platform at feldlazarete 11 in porchow near east Prussia. The info also includes the fact he was buried on the western side of a sports field near the hospital in a military cemetery.
I was most impressed at the detail of the info.
Does anyone here study, specialize in field hospitals?????
It's a big ask, but if you don't ask you never know
