How can I find a Re-buried pow from Stalag IV B?

Perhaps helpful:
I suspect that Stillwell was transferred with other British PoWs from Camp IV B to the Kriegsgefangegen-Reservelazarett Zeithain in the winter of 1944/45 due to acute accommodation problems. He may also have contracted typhus there.
(In fact, it was more a mortuary camp than a hospital for Soviet PoW with typhus)

All dead were buried at the Bad Liebenwerda-Neuburxdorf military cemetery. According to the memorial plaque, 50 British nationals were buried there, all of whom were reburied
