flotilla outgunned, and hence was able to fend off, the boats from the British ships. Battles continued through June 10. The British, frustrated by their inability to flush Barney out of his safe retreat, proceeded to raid several nearby Maryland settlements; sacking and burning Calverton, Huntingtown, Prince Frederick, Benedict and Lower Marlboro. Among the British units that participated in the campaign were a battalion of Royal Marines and the Corps of Colonial Marines, a unit consisting of enslaved African Americans who had deserted their enslavers and joined the British. Battle of St. Leonard's Creek On June 26, after the arrival of troops commanded by U.S. Army Colonel Decius Wadsworth, and U.S. Marine Captain Samuel Miller, Barney attempted a breakout. A simultaneous attack from land and sea on the blockading frigates at the mouth of St. Leonard's creek allowed the flotilla to move out of the creek and up-river to Benedict, Maryland, though Barney had to scuttle gunboats 137 and 138 in the creek. The British entered the then-abandoned creek and burned the town of St. Leonard, Maryland. The British, under the command of Admiral Sir Alexander Cochrane, moved up the Patuxent, preparing for a landing at Benedict, Maryland. For several days the British fleet bombarded the Flotilla with cannon and congreve rockets in an attempt to destroy it. August 11, 1814, the Flotilla left St. Leonard's Creek and sailed north up the Patuxent River. A plan had been discussed to transport the entire Flotilla overland from the port of Queen Anne to the South River and return it to the Bay. However, concerned that the Flotilla would fall into British hands, Secretary of the Navy Jones ordered Barney to take his squadron as far up the Patuxent as possible, to Queen Anne, and scuttle the vessels should the British appear. On 22 August the British approached the Flotilla, and Barney ordered its destruction. He then force-marched the men from the flotilla and such cannons as were movable, to Washington D.C. where they were to join the Battle of Bladensburg. Three active battalions of the Regular Army (1-4 Inf, 2-4 Inf and 3-4 Inf) perpetuate the lineages of the old 36th and 38th Infantry Regiments, both of which had elements that participated in the Battle of St. Leonard's Creek. Battle of Queen Anne On August 22, the British attempted to capture Barney's squadron at Queen Anne. In his report of the
