Jefferson Patterson Park and Museum

Jefferson Patterson Park and Museum (JPPM) is a MD state museum of history and archaeology whose mission is to preserve, research, and interpret the diverse cultures of the Chesapeake Bay region. Located in Calvert Co. on a 560-acre property along the Patuxent River and St. Leonard Creek, it is listed on the National Register of Historic Places. The  Battle of St. Leonard Creek, a large War of 1812 naval engagement, took place where the Patuxent River meets the mouth of St. Leonard Creek, right off the shore of JPPM.. Charles Ball, a Calvert Co. resident who wrote a narrative of his life in enslavement and his escape to freedom in the North, described fighting in this battle in his book, Slavery in the United States: A Narrative of the Life and Adventures of Charles Ball. A large portion of the property that is now JPPM was owned by George Peterson at the beginning of the Civil War. According to the 1850 census, Peterson enslaved 16 people. At least two of them, William Coates and William Jones, enlisted in the USCT and were freed.
