Thanks for your response. My Great-Grandfather went to Alton Prison Oct 28, 1863. I know that both of these men were lucky to even survive because they came into the prison right after the smallpox outbreak. I'm trying to find out the procedures for release. My Great-Grandfather was released on Oath and $1,000 bond. John Wesley Brock was released on Oath alone, apparently both times. Thanks for any information given.
