The details of the engagement are useless--there was a show of resistance and some well sustained firing for awhile; but the whole battle, so far as it can be called one, was fought by Barney. He had planted four guns, among them an eighteen pounder, so as to sweep the main road, and quietly sat beside them on his bay horse, allowing the column to come within close range before he gave orders to fire. The first terrible discharge cleared the road. Three times the British endeavored to advance in front, and as often were swept to destruction by that battery. At length they were compelled to abandon the attempt, and taking shelter under a ravine filed off to the right and left and assailed Barney in flank and rear. Driving easily before them the regiments whose duty it was to protect the artillery, they moved swiftly forward. Barney's horse had been shot under him and he himself, prostrated by a wound, lay stretched in the road. Seeing that the battle was lost, he bade his seamen cut their way through the enemy and escape. Reluctant at first to obey him, they at last fled, and their gallant commander was taken prisoner. A few such determined men would have saved Washington from the flames. The six hundred Virginians who had hastened to the rescue never joined the army at all. Having arrived without arms, they slept in the House of Representatives all night and were not equipped next day till the battle was over. The _retreat_ became a wild and shameful flight. No other stand was made, and the fugitive army fled unpursued in squads hither and thither. It was a regular stampede. The fields and roads were covered with a broken and flying multitude. President, secretaries of war and navy, attorney-general and all were borne away in the headlong torrent; and though the enemy had no cavalry to pursue, and the infantry were too tired to follow up their success, the panic was so complete and ridiculous that our troops never stopped their flight except when compelled to pause from sheer exhaustion. Fatigue, not the interval they had put between themselves and the enemy, arrested their footsteps. Only fifty or sixty had been killed on our side, while the British had lost several hundred, a large portion of whom fell under the murderous discharges of Barney's battery. After the shouts and derision of the enemy had subsided with the disappearance of the last fugitive over the hills, the tired army instead of advancing to Washington reposed on the field of battle. Winder endeavored to rally the troops at the capital for another defence, but not a sufficient number could be found to make a stand, and with curses and oaths the rabble rout streamed along the road to Georgetown, presenting a picture of demoralization and insubordination that formed a fit counterpart to their poltroonry.
