“In a short while General McClellan came from his headquarters near the battleground, joined the President, and with him reviewed the troops at Bolivar Heights that afternoon, and at night returned to his headquarters, leaving the President at Harper’s Ferry. “On the morning of the second, the President, with General Sumner, reviewed the troops respectively at Loudon Heights and Maryland Heights, and at about noon started to General McClellan’s headquarters, reaching there only in time to see very little before night. “On the morning of the third all started on a review of the Third Corps and the cavalry, in the vicinity of the Antietam battle-ground. After getting through with General Burnside’s corps, at the suggestion of General McClellan, he and the President left their horses to be led, and went into an ambulance to go to General Fitz John Porter’s corps, which was two or three miles distant. “I am not sure whether the President and General McClellan were in the same ambulance, or in different ones; but myself and some others were in the same with the President. On the way, and on no part of the battleground, and on what suggestions I do not remember, the President asked me to sing the little sad song that follows (“Twenty Years Ago, Tom”), which he had often heard me sing, and had always seemed to like very much. “After it was over, some one of the party (I do not think it was the President) asked me to sing something else; and I sang two or three little comic things, of which ‘Picayune Butler’ was one. Porter’s corps was reached and reviewed; then the battle-ground was passed over, and the most noted parts examined; then, in succession, the cavalry and Franklin’s corps were reviewed, and the President and party returned to General McClellan’s headquarters at the end of a very hard, hot and dusty day’s work. “Next day (the 4th), the President and General McClellan visited such of the wounded as still remained in the vicinity, including the now lamented General Richardson; then proceeded to and examined the South-Mountain battle-ground, at which point they parted, General McClellan returning to his camp, and the President returning to Washington, seeing, on the way, General Hartsoff, who lay wounded at Frederick Town. “This is the whole story of the singing and its surroundings. Neither General McClellan nor any one else made any objections to the singing; the place was not on the battle-field; the time was sixteen days after the battle; no dead body was seen during the whole time the President was absent from Washington, nor even a grave that had not been rained on since the time it was made.” “ONE WAR AT A TIME.”
