Thomas P Preston, his record indicates he was wounded in the hip, admitted Resaca, Ga., Dept. of the Cumberland field hospital May 20, 1864, died June 8. Another card states he was killed May 15, 1864. I believe the two records shown in the American CW Research Database below are two and the same men.

Other than Thomas, the only other Preston on the regimental rolls was Sergeant Major Joshua E. Preston.

Given that, there is an outside chance that "The Medical and Surgical History of the Civil War" could conceivably indicate when and where buried. My best guess is that those who died in a field hospital were buried closely nearby, and being Rebels, unmarked.

Someone on these message boards has access to these records, I do not know where they are found.
