I am doing family research and have hit a bump. My great great grandfather Charles W. Lange (1891) born , joined up after he graduated from the Malerschule, a private art school- in Buxtehude in March 1912. His graduation picture shows all the boys in uniform. He was from Hamburg but spent time in Bremen, so I assume he joined up in one of those towns. I also am assuming he was infantry.
He was captured as a POW and sent to England...and that is all we know about the way, except a handful of old cigarette cards from the trenches.
I am searching for some sort of record, they seem awfully hard to track down.
Any ideas? I would very much appreciate any guidance.
