I have an ancestor 2nd Lieutenant RTM Simmons of the 40th AL inf. that according to his service record was captured at Big Shanty (listed as private RTM Simmons 40th AL on the card) It says he was captured on June 15th and "forwarded" on June 17th. However I have an abstracted transcription of one of his letters dated June 18 and he is in the hospital in Marietta with an "old" wound suffered at Chickamauga.
the letter dated June 18 1864 is addressed from "Division Hospital, Marietta, GA.

the next letter is addressed Stuart's Division Hospital Marietta, GA June 24, 1864

Here are the questions:
1. Does anyone know where Stuart's division hospital was located at these times (and was it at the same place both times and does the building/s still exist) as I know some former hospitals still do.

2. Are there any hospital records for this one and if so would the men be listed with their maladies and when they were admitted?
