I have an interesting story. My g-g-grandfather was in the 25th/28th Tenn Inf. He was captured after being left behind when Bragg retreated to Chattanooga. He and his brother had just come back from a hospital in Atlanta and were too sick to march. Ed was sent to Camp Chase while his brother was told they would come back for him when he was well enough to travel to a POW camp. They eventually paroled him instead. Ed's health was broken at Camp Chase, a real hell-hole, and when he took the oath at the end of the war, they gave him a transportation voucher to ride the trains as far as Columbia, Tenn. He lived in White County and walked the rest of the way. The voucher had another man's name on it, and Ed was illiterate. I don't know how the other guy swapped with him, but when I finally was able to read his name, the guy's records showed him to be a pretty shady character.
