I, too, am looking for additional information on the 7th. My husband's gggf was Thomas Cothran (also spelled Cawthon, etc.) whose tombstone shows "PVT US ARMY CIVIL WAR CO A 7 ALA MISS TENN CSA." On the website previously provided in the above post, I found a John O. Cawthon who became a POW in Franklin, TN, but no mention of Thomas. Also, can anyone enlighten me as to what "CSA" means?
