This letter from a prisoner named Thomas Skinner was written just five days after the prison had opened. It is very informative letter and one of the earliest examples of prison letters.

Johnson's Island April 15, 1862

Dear Pa,

I was very sorry indeed that I had to leave Camp Chase just at the time when I was most looking for you to visit me. Camp Chase is not to be compared at all with this place neither in health or comfort. Although we had to forsake a great many things in the furniture line (such as chairs tables plates cups dishes &etc. and also a Negro boy that we had hired who was a splendid cook) I think the Comforts of this place will compensate for them all. This must be a very healthy climate. There is always a cool invigorating breeze from the lake such as I never felt before. We are almost three miles from Sandusky, Ohio. Sandusky is a very nice looking place. We, being the first Secesh they had ever seen. I have purchased such clothes as I most needed with the money you sent me. I will copy from my book my expenses since I have been a prisoner and send to you. I would be very glad to see you if you will be permitted to come. We are in very comfortable quarters only four in a room the houses are two storys high large windows and are plenty nice for soldiers. Write to me soon and often give me all the news. Why Dint Jim Murphy write to me Aunt Lilly and Aunt Marion Belle. Give My love to all the Family

I remain Your Affectionate Son
Thos. C. Skinner.
