I am searching for my great grandfather Ismailov Isa Iskander's grave.
He was born in 1904 in Khanlar (Helenendorf), Azerbaijan. That city was founded by Germans.
Isa learned German language from his friends in Khanlar. In 1941 he went to the war. My grandpa was a Soviet soldier. When he took part in World War II he was captured in December 1941. According to official Soviet archives he wais missing.
After the Collapse of the Soviet Union a man who was also in captivity told told me that he saw Isa in Graz, Austria in 1944. Isa was captured by Germans in Graz, Austria and has a berth among the other captives.
Can anyone suggest how I can find out what happened to him after he was captured, and/or confirm any of the details of his capture and captivity above?
