The ground on the eastern side of the river, where the British approached, was low and clear. On the western it rose in a gradual slope, and along the stream was fringed with willows and larches. A body of American riflemen was posted in the shrubbery that lined the bank. Three hundred yards up the slope was a slight earthwork, mounting six guns, supported by two companies of Baltimore volunteers. General Stansbury had posted three regiments to the right of it, but Secretary Monroe had moved them to a point in the rear of the battery and five hundred yards farther up the slope. At the top of the hill, one mile from the bridge, was formed a line consisting of Maryland militia on the right, Barney's seamen and marines in the centre, a detachment of regular troops and a regiment of District militia on the left, with a battery of six guns and a company of riflemen in front.
The enemy entered the village of Bladensburg soon after noon of the 24th, and was at once subjected to a fire that compelled him to seek the shelter of the houses. At one o'clock the advance column rushed at the double quick upon the bridge, where it met a concentrated fire from the American batteries and riflemen, and almost entirely melted away. A remnant, however, succeeded in crossing, deployed at once, and advanced upon the first line, which fell back and permitted two guns to be lost.
Elated at this success, the thin line of British troops threw off their knapsacks and advanced toward the second line, without waiting for another column to cross the bridge to their support. When General Winder saw their error, he placed himself at the head of a regiment of Baltimore volunteers, gave them an effective volley, and then made a charge, and at the point of the bayonet drove them down to the very brink of the river, where with difficulty they maintained their foothold under the trees till another brigade had crossed the bridge to their relief.
One regiment of these fresh troops turned the left of the American line, and threw in some Congreve rockets, which so frightened the militia on that flank that they broke at once and fled in confusion. The regiment headed by Winder stood firm till both its flanks were turned, when it retired, its retreat being covered by the riflemen.
The enemy then attacked the remainder of the line, all of which soon gave way, except Barney's men, who kept them in check for half an hour, and with the fire of four pieces of artillery ploughed their ranks through and through. But when the militia broke, the teamsters stampeded, without stopping to unhitch their horses from the ammunition wagons. Barney was thus left with but a single round of ammunition, while the enemy was gradually gaining a position upon his flank; and though many of his men were acting as infantry and behaved admirably, charging several times with great effect, he was obliged to order a retreat. He himself had been severely wounded, while two of his principal officers were killed, and two others wounded. He fell into the hands of the enemy, who took him to their hospital at Bladensburg. In this action the Americans had lost seventy-seven men killed or wounded; the British, more than five hundred. Ross's entire loss, including deserters, prisoners, and those who succumbed to the weather, was said to be nearly a thousand.
But no serious obstacle now stood in the way of General Ross's purpose to destroy the capital; and with that portion of his force which had not been engaged, he marched thither without the loss of an hour, arriving at eight o'clock that evening.
The most valuable portion of the public archives had been removed to a place of safety, and Mrs. Madison had managed to carry away the original draft of the Declaration of Independence, a portrait of Washington that hung in the White House, and a few other articles which could not have been replaced. The magazines and shipping at the Navy Yard had already been fired by order of the Secretary of War, and everything there was destroyed.
It is said that General Ross offered to spare the city for a price; but there was no one at hand who could treat with him, if the authorities had been inclined to purchase its safety. He expected to be attacked by a more formidable force than that he had met at Brudensburg, and, as he wrote to Earl Bathurst, "judging it of consequence to complete the destruction of the public buildings with the least possible delay, so that the army might retire without loss of time, he without a moment's delay burned and destroyed everything in the most distant degree connected with the government." There was one notable exception. At the intercession of Dr. Thornton, who superintended the Patent Office, the building containing that and the Post Office was spared; because, as the doctor represented, it contained great numbers of models and papers which were of value to the whole scientific world. The jail, one hotel, and a few dwellings also escaped. All else, including the President's house, the public libraries, and the new Capitol—of which only the wings had been built—was given to the flames. The commanders of the expedition distinguished themselves personally in this vandalism. Admiral Cochrane, who had a spite against the National Intelligencer because of its strictures upon his marauding exploits along the coast, caused the office to be sacked and the type thrown into, the street, and with his own hand set the building on fire. Admiral Cockburn is said to have led his men into the hall of the House of Representatives, where he leaped into the Speaker's chair and shouted, "Shall this harbor of Yankee democracy be burned? All for it will say, Aye!"
In the night of the 25th, Ross silently withdrew from the city, leaving his camp-fires burning, for he expected and feared pursuit-, and marched with all that remained of his force to Benedict, where they reëmbarked.
A division of the enemy's fleet, consisting of eight vessels, ascended the Potomac to attack the city of Alexandria. Fort Warburton, a small work intended for its defence, was destroyed by the garrison at the approach of the ships, and with no opposition they passed up and laid the town under their guns. A parley was had, the result of which was that the dwellings were left unmolested, the condition being, "the immediate delivery [to the enemy] of all public and private naval and ordnance stores; of all shipping, and the furniture necessary to their equipment then in port; of all the merchandise of every description, whether in the town or removed from it since the 19th of the month; that such merchandise should be put on board the shipping at the expense of the owners; and that all vessels which might have been sunk upon the approach of the fleet should be raised by the merchants and delivered up with all their apparatus." These conditions, hard as they were, were complied with, and on the 6th of September the fleet, loaded with booty, returned down the river. Two batteries on the shore—at White House and Indian Head, commanded by Captains Porter and Perry, of the navy—damaged it considerably as it passed, but were not able to stop it.
