…The others were captured; four on the same evening, and two others the next day. I was one of those captured on the same evening. Shortly after that, they removed us to the barracks in town, where we were better treated, more kindly treated than we had ever been before that. We remained there until December, when we were sent to Richmond. We were first taken to the Libby Prison, and told that we were to be exchanged. They sent a very light guard along with us, trusting to our belief that we would be exchanged; and so believing, we went along quietly and made no attempt to escape, which we could easily have done. We were taken to the Libby Prison and kept there about an hour, and then transferred to the criminal prison, Castle Thunder. Here we were put into a little room up stairs, of which three sides were only weatherboarded, and there we remained during the months of December and January, without any fire, and with a very scanty supply of clothing, as they had taken all our blankets from us when we left Atlanta, with the exception of two small ones, which we had managed to secrete when we left the barracks. This was the only covering we had during those two months for all six of us there. We were very destitute of other clothing at that time-nearly out of it, in fat. About the 1st of February, however, they wanted that room, with a number of other rooms on the same floor, for hospital purposes, and transferred us to a large room down stairs on the ground floor, which was assigned Union prisoners. Here we enjoyed more liberty than we had before, and remained until a special exchange was made. They attempted to exchange us as citizens, leaving our name on the citizens’ list from Castle Thunder, although we had our names marked as soldiers, and our companies and regiments were down on the prison books; and, in the charges and specifications given to the seven of our comrades who were tried and executed, it was admitted that they were soldiers, and their companies and regiments were named.
