Was Gratiot the only prison in St. Louis?
No. There were a number of other prisons and buildings used besides Gratiot, but they all fell under Gratiot’s administration (which was run by the Provost Marshal) and were, effectively, part of Gratiot. Other prisons include Myrtle Street Prison which was a confiscated slave pen known as Lynch’s Slave Pen (confiscated from Bernard Lynch), Chesnut Street Prison which was the confiscated home of Margaret McLure and was used to hold women, and a variety of other buildings in the area surrounding Gratiot.
