At daybreak on the morning of the nineteenth it was discovered that the enemy had departed during the night and the last of their rear guard was then crossing the Potomac at Shepherdstown ford. General Porter's Corps was ordered to the ford. On the way we passed through a part of the battlefield, which was still strewn with Rebel corpses. Most of them had turned so black that they looked almost like negroes and their heads and bodies had swollen to an enormous size. It was a horrible sight. We passed through the town of Sharpsburg and beyond that through some of the deserted Rebel camps, where fires were still burning and there was every evidence of hasty departure.

When we approached the ford there was much artillery firing from Rebel batteries posted on the hills on the other side of the Potomac, which was replied to by some of our batteries. Sharp-shooters were posted at the river-bank and canal, firing at the enemy opposite. Towards evening a regiment of the First Division and the sharp-shooters crossed the river by fording and found a lodgment on the other side, capturing a few guns.

Early on the morning of the twentieth our brigade and the Fifth New York of the Third Brigade were ordered to ford the river and make a reconnaissance on the Charlestown road. General Sykes himself accompanied the brigade. We deployed as skirmishers, advanced about a mile and halted in some woods, when it was discovered that a large force of the enemy was rapidly approaching with artillery. General Sykes ordered the brigade to fall back slowly to the bluffs on the river-bank. In the meantime Barnes's Brigade of the First Division of the Fifth Corps had also crossed the river to go to Shepherdstown, but General Sykes ordered them to take a position on the heights near where they had crossed, to our right, where their skirmishers soon became engaged with the approaching enemy and brought on a spirited engagement. General Sykes, who informed General Porter of the large force opposed to his two small brigades, was ordered immediately to recross all the troops. This we were enabled to do in good order by the aid of a number of our batteries, posted on the heights on the Maryland side. These batteries delivered a destructive fire over our heads which kept the enemy from the river-bank, or it would have gone hard with us while fording the river. Before night all our troops had recrossed the Potomac.

This engagement at Shepherdstown ended the Maryland campaign. The loss on our side was about five hundred and, with the exception of nineteen, was all in General Barnes's brigade. The loss in my battalion was one killed and two wounded. Later it was learned that the retreating foe had turned back nine brigades of infantry with artillery under Generals Early and Hill to oppose us at Shepherdstown. No doubt they over-estimated our numbers and thought we were an army corps instead of two weak brigades. We then realized what great peril we had been in.

A daring act was performed by First Sergeant Daniel W. Burke of Company B, as we re-crossed the Potomac. He voluntarily attempted to spike some abandoned Rebel guns near the shore under a withering fire from the enemy. He received a commission soon after and was retired in 1899 as a brigadier-general and medal-of-honor man.

The next day we established a permanent camp in some woods near Sharpsburg, where we remained for more than six weeks and received a detachment of recruits during our stay, which somewhat replenished our skeleton companies. Four companies of the Seventh Infantry also joined our brigade at this place. They were a part of the troops surrendered in Texas, who were paroled at the time and had since been exchanged.

A few days after we had settled down to our regular camp duties I was much surprised when the first sergeant of my company informed me that I had been detailed to report to Lieutenant Hawkins as brigade commissary sergeant. This was promotion to a post usually filled by an older and more experienced soldier. My comrades congratulated me and said I was in luck to get that position—one that was greatly desired. I was not much elated over it, however, and seriously considered whether I should not ask to be excused and remain with my company.

By this time the sergeant major and half a dozen of the first sergeants of the companies had received commissions as second lieutenants, and without exception they made good officers and gave the regiment a better character and standing than the inexperienced civilians that had been inflicted upon us at the beginning of the war, many of whom we had since got rid of. All of these sergeants were older than I and had been longer in the service; I had only just turned twenty-one and looked much younger. With the exceptions of our two musicians, I was the youngest soldier in the company, until some recruits joined us a while later. I had learned from the sergeant major that my name had been mentioned in the regimental report for good conduct in battle, along with those of some other non-commissioned officers.

I had spoken to a couple of our officers, who were most friendly to me, about applying for a commission, and was advised to wait until I should be first sergeant of a company. This seemed a long way off, as I was only the third sergeant of the company at the time. I realized that if I left the company on special duty, to act as brigade commissary sergeant, the man who remained in the ranks would get the preference in promotion, other reasons being equal. On the other hand the position offered many advantages and was less arduous than that of a company officer. No more marching—I would have a horse to ride; no more guard and picket duties; no more standing in ranks to be fired at for hours by the enemy. The worst that had befallen the army trains thus far had been guerrilla attacks and captures by the enemy. So far I had been so lucky as to escape without a scratch, but I had seen many of my comrades fall in battle while in the ranks, and it might be my turn in the very next engagement. I decided to hold the position and left my company to report to the acting commissary officer at brigade headquarters. There was no extra pay attached to the position. I was carried on the company's muster rolls as "absent on special duty."

First Lieutenant Hamilton S. Hawkins of the Sixth United States Infantry was acting as the brigade commissary and quartermaster. He was a West Point graduate and a gentleman—one of the finest officers I met in the service. He was very dignified, honorable and just, kind and pleasant with his inferiors in rank—one of Nature's noblemen. In after years he was called the "Sir Henry Havelock" of the American Army. In the Spanish War he was a major-general of volunteers and commanded the division that captured San Juan Hill. He retired in 1898 as a brigadier-general of the United States Army, and at his death (which occurred recently) he was the governor of the Soldiers' Home in Washington, D.C.
