After a brave and obstinate contest, lasting all day on the 30th, in which a victory should have been won, but was lost through the defection and petty jealousies of some leading officers, the Union forces yielded the ground and fell back toward Washington.
On the night of Sep't 1st, we picketed on the flank of the army camped at Centreville, then joined in the general retreat and finally went into camp at Upton's hill, near Alexandria.
September 6th, we moved across the Long Bridge, through Washington city, to Leesboro, Md. where we went into camp.
The Rebel army under Gen'l Lee, has crossed the Potomac near Point of Rocks, and it is his intention to "liberate Maryland, and invade Pennsylvania."
His plan is to hold the gaps across South Mountain, and push his army north through the rich and beautiful Cumberland valley, "cut his way to Philadelphia, and dictate terms of peace in Independence Square."
On September 14th, the Union army found the enemy well posted on the mountain twelve miles west of Frederick city, and four miles from Middletown, and the Union veterans of the Peninsula, hurried up to meet him. Reaching the foot of the mountain after a hurried march, we file to the right, then face to the front, and begin the ascent of the mountain. Onward, upward we sweep, like a great tidal wave, the foot of the last acclivity is reached, then with a cheer, we cross the stone wall in our front, and with a rush up through the corn field, then a short, desperate, decisive struggle, and the battle of South Mountain is won.
Lieut. J. D. Sadler in command of the company fell while gallantly leading his men in this charge, and at the same moment Jere. Naylor and Peter Miller, were killed, while Lieut. H. N. Minnigh and several men were wounded, leaving the company without a commissioned officer, Capt. Stewart still being absent, on account of wounds.
On September 17th, the command was at Antietam, and took its place in line, though the company only numbered ten or twelve men for duty, and were led by Serg't Kitzmiller, and fortunately no casualties occurred, during that terrible struggle.
