Though a losing battle, the Union armies had made a splendid fight at Second Manassas. The stand at Ox Hill was severe; severe till the march of retreat, so that the Army of Northern Virginia should have held in profound respect its formidable adversary, seasoned by many bloody fields.
The policy of the Richmond government was defensive rather than aggressive warfare, but the situation called for action, and there was but one opening,—across the Potomac. General Lee decided to follow his success in its natural leading, and so reported to the Richmond authorities.
He was not so well equipped as an army of invasion should be, but the many friends in Maryland and the fields on the north side of the Potomac were more inviting than those of Virginia, so freely foraged. He knew from events of the past that his army was equal to the service to which he thought to call it, and ripe for the adventure; that he could march into Maryland and remain until the season for the enemy’s return into Virginia for autumn or winter work had passed, improve his transportation supplies, and the clothing of his army, and do that, if not more, for relief of our Southern fields and limited means, besides giving his army and cause a moral influence of great effect at home and abroad. He decided to make his march by the most direct route from Chantilly, where he had last fought, to the Potomac, and so crossed by the fords near Leesburg. Marching by this route, he thought to cut off a formidable force of Union troops at Winchester, at Martinsburg, and a strong garrison occupying the fortified position at Harper’s Ferry.
To summarize the situation, we were obliged to go into Maryland or retreat to points more convenient to supplies and the protection of Richmond.
At Leesburg Lee learned that the Union troops in the Valley had left Winchester, and sent back orders to have the crippled and feeble soldiers wending their way to the army march through the Valley to join us in Maryland. Trains of supplies were ordered to move by the same route.
On the 5th and 6th the columns crossed the Potomac by the fords near Leesburg. Stuart’s cavalry, coming up from the line near Alexandria and the Long Bridge, passed to front and right flank of the army. General McLaws’s division, General J. G. Walker, with two brigades of his division, and General Hampton’s cavalry brigade, including Colonel Baker’s North Carolina regiment, joined us on the march. On the 7th our infantry and artillery commands came together near Frederick City.
Riding together before we reached Frederick, the sound of artillery fire came from the direction of Point of Rocks and Harper’s Ferry, from which General Lee inferred that the enemy was concentrating his forces from the Valley, for defence at Harper’s Ferry, and proposed to me to organize forces to surround and capture the works and the garrison.
I thought it a venture not worth the game, and suggested, as we were in the enemy’s country and presence, that he would be advised of any move that we made in a few hours after it was set on foot; that the Union army, though beaten, was not disorganized; that we knew a number of their officers who could put it in order and march against us, if they found us exposed, and make serious trouble before the capture could be accomplished; that our men were worn by very severe and protracted service, and in need of repose; that as long as we had them in hand we were masters of the situation, but dispersed into many fragments, our strength must be greatly reduced. As the subject was not continued, I supposed that it was a mere expression of passing thought, until, the day after we reached Frederick, upon going over to head-quarters, I found the front of the general’s tent closed and tied. Upon inquiring of a member of the staff, I was told that he was inside with General Jackson. As I had not been called, I turned to go away, when General Lee, recognizing my voice, called me in. The plan had been arranged. Jackson, with his three divisions, was to recross the Potomac by the fords above Harper’s Ferry, march via Martinsburg to Bolivar Heights; McLaws’s division by Crampton’s Gap to Maryland Heights; J. G. Walker’s division to recross at Cheek’s Ford and occupy Loudoun Heights, these heights overlooking the positions of the garrison of Harper’s Ferry; D. H. Hill’s division to march by the National road over South Mountain at Turner’s Gap, and halt at the western base, to guard trains, intercept fugitives from Harper’s Ferry, and support the cavalry, if needed; the cavalry to face the enemy and embarrass his movements. I was to march over the mountain by Turner’s Gap to Hagerstown.
As their minds were settled firmly upon the enterprise, I offered no opposition further than to ask that the order be so modified as to allow me to send R. H. Anderson’s division with McLaws and to halt my own column near the point designated for bivouac of General D. H. Hill’s command. These suggestions were accepted, and the order[55] so framed was issued.
It may be well to digress from my narrative for a moment just here to remark that General Lee’s confidence in the strength of his army, the situation of affairs, and the value of the moral effect upon the country, North and South, was made fully manifest by the nature of the campaign he had just entered upon, especially that portion of it directed against Harper’s Ferry, which, as events were soon to prove, weakened the effectiveness of his army in the main issue, which happened to be Antietam.
