In the recent attempt of the enemy on the city of Baltimore, defended by militia and volunteers, aided by a small body of regulars and sea men, he was received with a spirit which produced a rapid retreat to his ships, whilst concurrent attack by a large fleet was successfully resisted by the steady and well-directed fire of the fort and batteries opposed to it. In another recent attack by a powerful force on our troops at Plattsburg, of which regulars made a part only, the enemy, after a perseverance for many hours, was finally compelled to seek safety in a hasty retreat, with our gallant bands pressing upon them. On the Lakes, so much contested throughout the war, the great exertions for the command made on our part have been well repaid. On Lake Ontario our squadron is now and has been for some time in a condition to confine that of the enemy to his own port, and to favor the operations of our land forces on that frontier. A part of the squadron on Lake Erie has been extended into Lake Huron, and has produced the advantage of displaying our command on that lake also. One object of the expedition was the reduction of Mackinaw, which followed with the loss of a few brave men, among whom was an officer justly distinguished for his gallant exploits. The expedition, ably conducted by both the land and the naval commanders, was otherwise highly valuable in its effects. On Lake Champlain, where our superiority had for some time been undisputed, the British squadron lately came into action with the American, commanded by Captain Macdonough. It issued in the capture of the whole of the enemy's ships. The best praise for this officer and his intrepid comrades is in the likeness of his triumph to the illustrious victory which immortalized another officer and established at a critical moment our command of another lake. On the ocean the pride of our naval arms had been amply supported. A second frigate has indeed fallen into the hands of the enemy, but the loss is hidden in the blaze of heroism with which she was defended. Captain Porter, who commanded her, and whose previous career had been distinguished by daring enterprise and by fertility of genius, maintained a sanguinary contest against two ships, one of them superior to his own, and under other severe disadvantages, 'til humanity tore down the colors which valor had nailed to the mast. This officer and his brave comrades have added much to the rising glory of the American flag, and have merited all the effusions of gratitude which their country is ever ready to bestow on the champions of its rights and of its safety.
