Jackson began his march on September 10th with secret instructions from his commander to encompass and capture the Federal garrison and the vast store of war material at this place, made famous a few years before by old John Brown. To conceal his purpose from the inhabitants he inquired along the route about the roads leading into Pennsylvania. It was from his march through Frederick that the Barbara Frietchie story took its rise. But there is every reason to believe that General Jackson never saw the good old lady, that the story is a myth, and that Mr. Whittier, who has given us the popular poem under the title of her name, was misinformed. However, Colonel H. K. Douglas, who was a member of Jackson’s staff, relates, in “Battles and Leaders of the Civil War,” an interesting incident where his commander on entering Middletown was greeted by two young girls waving a Union flag. The general bowed to the young women, raised his hat, and remarked to some of his officers, “We evidently have no friends in this town.” Colonel Douglas concludes, “This is about the way he would have treated Barbara Frietchie.”

On the day after Jackson left Frederick he crossed the Potomac by means of a ford near Williamsport and on the 13th he reached Bolivar Heights. Harper’s Ferry lies in a deep basin formed by Maryland Heights on the north bank of the Potomac, Loudon Heights on the south bank, and Bolivar Heights on the west. The Shenandoah River breaks through the pass between Loudon and Bolivar Heights and the village lies between the two at the apex formed by the junction of the two rivers.

As Jackson approached the place by way of Bolivar Heights, Walker occupied Loudon Heights and McLaws invested Maryland Heights. All were unopposed except McLaws, who encountered Colonel Ford with a force to dispute his ascent. Ford, however, after some resistance, spiked his guns and retired to the Ferry, where Colonel Miles had remained with the greater portion of the Federal troops. Had Miles led his entire force to Maryland Heights he could no doubt have held his ground until McClellan came to his relief. But General Halleck had ordered him to hold Harper’s Ferry to the last, and Miles interpreted this order to mean that he must hold the town itself. He therefore failed to occupy the heights around it in sufficient strength and thus permitted himself to be caught in a trap.

During the day of the 14th the Confederate artillery was dragged up the mountain sides, and in the afternoon a heavy fire was opened on the doomed Federal garrison. On that day McClellan received word from Miles that the latter could hold out for two days longer and the commanding general sent word: “Hold out to the last extremity. If it is possible, reoccupy the Maryland Heights with your entire force. If you can do that I will certainly be able to relieve you.... Hold out to the last.” McClellan was approaching slowly and felt confident he could relieve the place.

On the morning of the 15th the roar of Confederate artillery again resounded from hill to hill. From Loudon to Maryland Heights the firing had begun and a little later the battle-flags of A. P. Hill rose on Bolivar Heights. Scarcely two hours had the firing continued when Colonel Miles raised the white flag at Harper’s Ferry and its garrison of 12,500, with vast military stores, passed into the hands of the Confederates. Colonel Miles was struck by a stray fragment of a Confederate shell which gave him a mortal wound. The force of General Franklin, preparing to move to the garrison’s relief, on the morning of the 15th noted that firing at the Ferry had ceased and suspected that the garrison had surrendered, as it had.

The Confederate Colonel Douglas, whose account of the surrender is both absorbing and authoritative, thus describes the surrender in “Battles and Leaders of the Civil War”:

“Under instructions from General Jackson, I rode up the pike and into the enemy’s lines to ascertain the purpose of the white flag. Near the top of the hill I met General White and staff and told him my mission. He replied that Colonel Miles had been mortally wounded, that he was in command and desired to have an interview with General Jackson.... I conducted them to General Jackson, whom I found sitting on his horse where I had left him.... The contrast in appearances there presented was striking. General White, riding a handsome black horse, was carefully dressed and had on untarnished gloves, boots, and sword. His staff were equally comely in costume. On the other hand, General Jackson was the dingiest, worst-dressed and worst-mounted general that a warrior who cared for good looks and style would wish to surrender to.

“General Jackson ... rode up to Bolivar and down into Harper’s Ferry. The curiosity in the Union army to see him was so great that the soldiers lined the sides of the road.... One man had an echo of response all about him when he said aloud: ‘Boys, he’s not much for looks, but if we’d had him we wouldn’t have been caught in this trap.’”

McClellan had failed to reach Harper’s Ferry in time to relieve it because he was detained at South Mountain by a considerable portion of Lee’s army under D. H. Hill and Longstreet. McClellan had come into possession of Lee’s general order, outlining the campaign. Discovering by this order that Lee had sent Jackson to attack Harper’s Ferry he made every effort to relieve it.

The affair at Harper’s Ferry, as that at South Mountain, was but a prelude to the tremendous battle that was to follow two days later on the banks of the little stream called Antietam Creek, in Maryland. When it was known that Lee had led his army across the Potomac the people were filled with consternation—the people, not only of the immediate vicinity, but of Harrisburg, of Baltimore, of Philadelphia. Their fear was intensified by the memory of the Second Bull Run of a few weeks earlier, and by the fact that at this very time General Bragg was marching northward across Kentucky with a great army, menacing Louisville and Cincinnati.
