At the break of day on the morning of the 30th of August, the troops were aroused from their slumbers and ordered to prepare for the great and decisive battle at hand. But hour after hour passed by, and except an occasional picket shot, all else was still. It was, though, but the calm which precedes the storm, for suddenly dense masses of the enemy emerged from the woods, and moved at the double-quick upon Jackson’s lines. It was a grand sight to see those three lines rush forward in the most beautiful order. For a minute a deathlike silence prevailed, when the very earth was made to tremble by the roar of Stephen D. Lee’s thirty-six pieces of artillery, fired at point blank range. The slaughter was appalling, and whole ranks melted away in an instant, but the brave survivors closed up their decimated columns, and despite that awful fire pressed on until they encountered the infantry posted in the railroad cut in front, where for a time the fight was waged hand to hand. At length they began to break and to retreat, and the batteries, which had been silent for some time owing to the proximity of the struggling columns of infantry, again belched forth into the fleeing mass their deadly discharges of grape, which was continued until the fugitives reached the shelter of the woods from which they had emerged. Of the several batteries under General Lee that day, not one was worked more fiercely than the Baltimore Light Artillery, and none contributed more to the defeat and destruction of the enemy. Long before nightfall the victory was won, and the braggart Pope, with the remnant of his army, was seeking safety in the defences around Washington. In the invasion of Maryland, which followed this signal victory, the battery was placed in the advance, and crossed the river at White’s Ford. On the 6th of September the battery passed through Frederick city, and encamped on the suburbs. Many were the congratulations the brave fellows received from the citizens, and during the three days they remained, their wants were abundantly supplied. Leaving Frederick city, the battery passed through Boonsboro, Middletown, and Williamsport, where they recrossed the Potomac, and on the 12th entered Martinsburg. From thence it moved towards Harper’s Ferry, when upon arriving at Loudoun Heights Brockenborough was assigned a position from which, at early dawn of the 15th, he opened, along with other batteries, a terrific fire upon the enemy’s entrenched position on Bolivar Heights. The batteries were worked furiously for an hour, when just as the Confederate infantry were put in motion to storm the works, a white flag fluttered in the breeze, and Harper’s Ferry surrendered with its twelve thousand troops, and artillery and supplies in abundance.
