The largest naval engagement in Maryland took place in St. Leonard Creek in June 1814. Americans prevailed in a series of skirmishes June 8-10, but the British ultimately trapped them in the creek. The first battle had little effect. On June 26, U.S. land units gave support from nearby heights. Following the intense fighting in the Second Battle of St. Leonard Creek, the Chesapeake Flotilla escaped up the Patuxent.
