Some more interesting details. I send a copy of the hospital records to Robert Phillips, my cousin and R. W. Rea's great grandson. He sent this interesting story:

Hi Ed, we’re fine, hope you are doing well. Thanks for the document, I wonder what he was in the hospital for, CSA records that late in the war are rare. I do know that after Nashville he was posted at Tupelo while the rest of the regiment went on to Mobile. Also years after the war he had a shoulder wound that would not heal properly. My grandmother, his daughter Mary, told me that as a teenager she was asked to probe the wound and was able to pull out a piece of uniform cloth. After that it healed up.

His brother, George Rea, was a Lt. in the 36th and was wounded mortally at Nashville. I saw this account on FindaGrave https://www.findagrave.com/memorial/117058418/george-w_-rea He was transported to Mobile during the retreat and died there in Feb. ‘65. They buried him at Hazelhurst.

I hope you can open the findagrave site listed above and click on the full story of Lt. George Rea, Co. C, 36th MS. Quite a story of courage! Perhaps as Sargent Clarke requested in his notes, we can remember: "He deserves to have his name inscribed on the eternal annals of fame...I cannot see why some of the Copiah friends of the young officer.... do not write, and have published, an account of his gallant conduct, in leading our Regiment to victory."
