While the British squadron was blockading the eastern coast during the summer of 1814, Commodore Barney sailed from Baltimore in command of a flotilla consisting of a cutter, two gun-boats, a galley, and nine large barges, for the protection of the inlets and harbours in the several parts of the bay. On the 1st of June, being at the mouth of the Patuxent, he discovered two schooners, one of which carried eighteen guns; and immediately gave chase. The schooners were joined, however, by a large ship, which despatched a number of barges to their assistance; and the commodore sailed up the Patuxent to avoid being cut off from the Potomac. The schooners and barges following him, he engaged and drove them back, and then anchored within three miles of the seventy-four. In the course of a few days, the enemy was reinforced by a rasee and a sloop of war; and joining the barges of these vessels, they followed the flotilla into St. Leonard’s Creek, across which Commodore Barney formed his boats in line of battle. A sharp engagement ensued, the enemy gave way, and the flotilla pursued them to within a short distance of their shipping. In the afternoon, the enemy made another attempt with twenty barges and two schooners. After a warm action, the barges were driven back upon the eighteen-gun schooner, which, in attempting to beat out, was so severely handled, that her crew ran her aground and abandoned her. On the 26th, a corps of artillery arrived from Washington to the commodore’s assistance, and a combined attack was made on the whole squadron. The action continued two hours; at the end of which the enemy’s ships were driven from their anchorage, and stood down the river. The cessation of hostilities in Europe, enabled the British government to send out powerful reinforcements to their fleets and armies in America; and Sir Alexander Cochrane soon arrived with thirty sail, having on board several thousand men, under command of Major General Ross. This force entered the Chesapeake, and a plan of attack on Washington, Alexandria, and Baltimore, was adopted. Admiral Cochrane very honourably informed the Secretary of State that he had orders to lay waste all the accessible towns on the coast; and the fleet, in two divisions, soon after approached the capital by the Potomac and the Patuxent.
