The order to withdraw, though sent by Hooker before the receipt of Sedgwick's despatch saying he would hold the corps south of the river, was received by Sedgwick long before the countermand, which was exceptionally delayed, and was at once, under the urgent circumstances, put into course of execution.
As soon as the enemy ascertained that Sedgwick was crossing, Alexander's artillery began dropping shells in the neighborhood of the bridges and river banks; and Gen. Wilcox, with his own and Kershaw's brigades, followed up Sedgwick's movements to the crossing, and used his artillery freely.
When the last column had almost filed upon the bridge, Sedgwick was taken aback by the receipt of Hooker's despatch of 1.20 A.M., countermanding the order to withdraw as above quoted.
The main portion, however, being already upon the left bank, the corps could not now re-cross, except by forcing the passage, as the Confederates absolutely commanded the bridge and approaches, and with a heavy body of troops. And, as Lee was fully satisfied to have got rid of Sedgwick, upon conditions which left him free to turn with the bulk of his army upon Hooker, it was not likely that Sedgwick could in any event have successfully attempted it. The situation left him no choice but to go into camp near by. An adequate force was sent to watch the ford, and guard the river.
The losses of the Sixth Corps during these two days' engagements were 4,925 men. Sedgwick captured, according to his report, five flags, fifteen guns (nine of which were brought off), and fourteen hundred prisoners, and lost no material. These captures are not conceded by the Confederate authorities, some of whom claim that Sedgwick decamped in such confusion as to leave the ground strewed with arms, accoutrements, and material of all kinds. But it is probable, on comparison of all facts, and the due weighing of all testimony, that substantially nothing was lost by the Sixth Corps, except a part of the weapons of the dead and wounded.
Gibbon's division, about the same time, crossed to the north bank of the river, and the pontoon bridge at Lacy's was taken up. Warren says, "Gen. Sedgwick was attacked very heavily on Monday, fought all day, and retreated across the river that night. We lay quiet at Chancellorsville pretty nearly all day." This Warren plainly esteems a poor sample of generalship, and he does not understand why Hooker did not order an assault. "I think it very probable we could have succeeded if it had been made." "Gen. Hooker appeared very much exhausted,"—"'tired' would express it."
Lee's one object having been to drive Sedgwick across the river, so as to be relieved of the troublesome insecurity of his rear, he could now again turn his undivided attention to his chief enemy, who lay listlessly expectant at Chancellorsville, and apparently oblivious of his maxim enjoined upon Stoneman, "that celerity, audacity, and resolution are every thing in war."
Early and Barksdale were left, as before, to hold the Confederate lines at and near Fredericksburg, while McLaws and Anderson were at once ordered back to the old battle-field. "They reached their destination during the afternoon (Tuesday, 5th) in the midst of a violent storm, which continued throughout the night, and most of the following day." (Lee.)
Wilcox and Wright lay that night in bivouac on the Catherine road; Mahone, Posey, and Perry, along the plank road.
Kershaw was sent to relieve Heth at the crossing of the River and Mine roads, and the latter rejoined his division.
