The defence of Baltimore was one of the most spirited of the many gallant actions on our sea-board and frontier during the late war; and it occurred more opportunely, as it followed so closely upon the defeat at Bladensburgh, which, though inevitable from the superior numbers of the enemy, was still accompanied with the mortification inseparable from such disaster.

After the embarkation of the troops under General Ross, (who had bought his victory at Bladensburgh with the loss of nearly a thousand men,) Admiral Cochrane concentrated his fleet, and made preparations for the attack on Baltimore. The whole squadron, amounting to forty vessels, sailed soon after for the Patapsco, and arriving near North Point, twelve miles from the city, the ships of the line anchored across the channel, and commenced the debarkation of troops. By the morning of the 12th of September about 8,000 soldiers, sailors, and marines, were in readiness to march upon the town, and sixteen bomb vessels and frigates proceeded up the river, and anchored within two miles and a half of Fort McHenry.

This garrison, which was mainly relied on for the protection of the city, was defended by about 5,000 men, and a detachment of about 3,000 was sent on by the North Point road to annoy or engage the enemy at his approach. Intelligence soon came in, that a light corps was advancing; and two companies of infantry, with a few riflemen, and ten artillerists with a single four-pounder, proceeded half a mile, and met and engaged the main body. The situation of the ground would not admit of the cooperation of the artillery and cavalry; and the infantry and riflemen sustained the whole action with great gallantry. The advance of the enemy was checked, and Major-General Ross and several other British officers killed.

The detachment now fell back upon the main line of the American force, and after some skirmishing with rockets and artillery at a distance, the whole force of the enemy pushed forward, and attacked the two regiments on the left with great impetuosity. These being thrown into confusion, a general fire was opened upon the British line, and a vigorous action followed, which lasted till four o’clock. At that hour the American force amounting to but about 1,400, and the British to about 7,000, General Stucker fell back upon the reserve regiment, and was joined by some other companies, who took position with him within half a mile of the entrenchments.

Early the following morning the Admiral made signals to the British officer in command on shore, that the frigates, bomb-ships, and flotilla of barges, would take their stations to bombard the town and fort in the course of the morning. The land forces accordingly moved forward, and took up a position two miles eastward of the entrenchments. The day was chiefly passed in manœuvring; but Colonel Brooke, after a vain attempt to make a detour through the country, concentrated the English force directly in front of the American line, drove in the outposts, and made preparations for an attack in the night.

The night was stormy; and in the morning it was discovered that the enemy had abandoned his position. The troops were re-embarked, and a bombardment commenced, which lasted till the following morning, during which a fleet of barges attempted to storm Fort Covington, but were repulsed with great loss. With the failure of this attempt the undertaking was abandoned altogether, and the fleet stood down the river.

When the bombardment commenced, the fort opened its batteries upon the ships; but, the shot falling short, the little garrison were compelled to keep their post without retaliation. There were four killed and twenty-four wounded in the entrenchments, and among the former were two very gallant young men, Lieutenants Clagett and Clem, volunteer officers.

The entire loss of the British could not be ascertained. That of the Americans on the field was about 150, which, added to those in the fort, makes a total of 178.
