Thanks, I agree. It makes me think there is some leadership or organization relationship between the Okolona facility and the facilities at Marion and Meridian (and, perhaps, Lauderdale Springs).
On J. D. Caldwell and Walter Curry the only information I have is that they were both original members of the 1st Alabama Infantry Regiment. Dr. Caldwell was the unit Surgeon and Dr. Curry was his Assistant Surgeon. Both appear to have been at Pensacola and Shiloh before "popping up" on the discharge.
Of Course, I'm mostly interested in their connection to the Marion Hospital and both appear to have played prominent roles in that (and the Meridian) facility. At some point, Dr. Curry was assigned to Gen. Johnston and was present at the Fall of Jackson. When his (Curry's) General Hospital was threatened, Johnston's Medical Director, Dr. Yandall (also an extremely important figure in Meridian and Marion hospitals) ordered him to "remove to Marion" and "establish" a hospital. Marion would have been in existance at this time and, based on the casuality information that I have, that was where he went.
I don't have any further on those two Surgeons. The discharge also indicates the present of G. A. Nott, another Surgeon and a J.(?) M. Hoyle, an Assistant Surgeon. Perhaps, researching these two (which I haven't started yet) would be productive.
Thanks for your help.
