Dozens upon dozens of undelivered letters from Confederate prisoners at Camp Chase were found in 1904. They as of yet are still sitting somewhere in Ohio.
Here is one such letter that was transcribed in 1906.
"Camp Chase, April 21,1862.
Dear Mother: My health is tolerably good at this time, but I have been very sick since I came here first, which was after Fort Donelson was taken. I guess I have got to stay here, for I see no chance of getting anywhere else. I hope the time will soon come when I may go home, but you need not look for me until you see me coming. We are treated much better than I expected. We have plenty to eat and good cabins to stay in. I send this by Mrs. Clark, who will take it to Richmond.
Yours until death, Uriah Gardner.
To Mrs. Mary Gardner, Jackson, West Tennessee."
