At the same time that McClellan was superseded, General FitzJohn Porter, the gallant soldier of Gaines’ Mill and Malvern Hill, probably the best officer in the Army of the Potomac, was ordered to resign command of the Fifth Army Corps, and to appear before a court-martial on charges of incompetency and neglect of duty at the Second Manassas. The fact that those charges were preferred by Pope, and that Porter had been allowed to retain his command through the campaign in Maryland, were hardly calculated to inspire the army with confidence in either the wisdom or the justice of its rulers; and it was the general opinion that his intimate friendship with McClellan had more to say to his trial than his alleged incompetency.

Burnside commenced his career by renouncing the enterprise which McClellan had contemplated. Longstreet was left unmolested at Culpeper; and, in order to free the communications from Jackson, the Federal army was marched eastward along the Rappahannock to Falmouth, a new line of supply being established between that village and Aquia Creek, the port on the Potomac, six hours’ sail from Washington.

Lee had already foreseen that Jackson’s presence in the Valley might induce the Federals to change their line of operations. Fredericksburg, on the south side of the Rappahannock, and the terminus of the Richmond and Potomac Railroad, had consequently been garrisoned by an infantry regiment and a battery, while three regiments of cavalry patrolled the river. This force, however, was not posted on the Rappahannock with a view of retarding the enemy’s advance, but merely for observation. Lee, at this date, had no intention of concentrating at Fredericksburg. The Federals, if they acted with resolution, could readily forestall him, and the line of the North Anna, a small but difficult stream, thirty-six miles south, offered peculiar advantages to the defence.

Nov. 17 The Federal march was rapid. On November 15 the Army of the Potomac left Warrenton, and the advanced guard reached Falmouth on the afternoon of the 17th. General Sumner, in command, observing the weakness of the Confederate garrison, requested permission from Burnside to cross the Rappahannock and establish himself on the further bank. Although two army corps were at hand, and the remainder were rapidly closing up, Burnside refused, for the bridges had been broken, and he was unwilling to expose part of his forces on the right bank with no means of retreat except a difficult and uncertain ford. The same day, part of Longstreet’s corps and a brigade of cavalry were sent to Fredericksburg; and on the 19th, Lee, finding that the Federals had left Warrenton, ordered Longstreet to concentrate his whole force at Fredericksburg, and summoned Jackson from the Valley to Orange Court House.

Jackson, meanwhile, had moved to Winchester, probably with the design of threatening the enemy’s garrisons on the Potomac, and this unexpected movement had caused much perturbation in the North. Pennsylvania and Maryland expected nothing less than instant invasion. The merchant feared for his strong-box, the farmer for his herds; plate was once more packed up; railway presidents demanded further protection for their lines; generals begged for reinforcements, and, according to the “Times” Correspondent, it was “the universal belief that Stonewall Jackson was ready to pounce upon Washington from the Shenandoah, and to capture President, Secretaries, and all.” But before apprehension increased to panic, before Mr. Lincoln had become infected by the prevailing uneasiness, the departure of the Confederates from the Valley brought relief to the affrighted citizens.

On November 22 Jackson bade farewell to Winchester. His headquarters were not more than a hundred yards from Dr. Graham’s manse, and he spent his last evening with his old friends. “He was in fine health and fine spirits,” wrote the minister’s wife to Mrs. Jackson. “The children begged to be permitted to sit up to see “General Jackson,” and he really seemed overjoyed to see them, played with them and fondled them, and they were equally pleased. I have no doubt it was a great recreation to him. He seemed to be living over last winter again, and talked a great deal about the hope of getting back to spend this winter with us, in the old room, which I told him I was keeping for you and him. He certainly has had adulation enough to spoil him, but it seems not to affect or harm him at all. He is the same humble, dependent Christian, desiring to give God all the glory, looking to Him alone for a blessing, and not thinking of himself.”

So it was with no presage that this was the last time he would look upon the scenes he loved that Jackson moved southward by the Valley turnpike. Past Kernstown his columns swept, past Middletown and Strasburg, and all the well-remembered fields of former triumphs; until the peaks of the Massanuttons threw their shadows across the highway, and the mighty bulk of the noble mountains, draped in the gold and crimson of the autumn, once more re-echoed to the tramp of his swift-footed veterans. Turning east at New Market, he struck upwards by the familiar road; and then, descending the narrow pass, he forded the Shenandoah, and crossing the Luray valley vanished in the forests of the Blue Ridge. Through the dark pines of Fisher’s Gap he led his soldiers down to the Virginia plains, and the rivers and the mountains knew him no more until their dead returned to them.

On the 26th the Second Army Corps was at Madison Court House.

Nov. 27 The next day it was concentrated at Orange Court House, six-and-thirty miles from Fredericksburg. In eight days, two being given to rest, the troops had marched one hundred and twenty miles, and with scarce a straggler, for the stern measures which had been taken to put discipline on a firmer basis, and to make the regimental officers do their duty, had already produced a salutary effect.

On Jackson’s arrival at Orange Court House he found the situation unchanged. Burnside, notwithstanding that heavy snow-storms and sharp frosts betokened the approach of winter, the season of impassable roads and swollen rivers, was still encamped near Falmouth. The difficulty of establishing a new base of supplies at Aquia Creek, and some delay on the part of the Washington authorities in furnishing him with a pontoon train, had kept him idle; but he had not relinquished his design of marching upon Richmond. His quiescence, however, together with the wishes of the President, had induced General Lee to change his plans. The Army of Northern Virginia, 78,500 strong, although, in order to induce the Federals to attack, it was not yet closely concentrated, was ready to oppose in full force the passage of the Rappahannock, and all thought of retiring to the North Anna had been abandoned.
