This movement undoubtedly lost General Hooker all the advantages which up to that moment he had secured. What his motive for the order in question was, it is impossible for the present writer to understand, unless the approach of Lee powerfully affected his imagination, and he supposed the thicket around Chancellorsville to be the best ground to receive that assault which the bold advance of his opponent appeared to foretell. Whatever his motive, General Hooker withdrew his lines from the open country, fell back to the vicinity of Chancellorsville, and began to erect elaborate defences, behind which to receive Lee's attack.
In this backward movement he was followed and harassed by the forces of Jackson, the command of Anderson being in front. Jackson's maxim was to always press an enemy when he was retiring; and no sooner had the Federal forces begun to move, than he made a prompt attack. He continued to follow them up toward Chancellorsville until nightfall, when the fighting ceased, the Confederate advance having been pushed to Alrich's house, within about two miles of Chancellorsville. Here the outer line of the Federal works was found, and Jackson paused. He was unwilling at so late an hour to attempt an assault upon them with his small force, and, directing further movements to cease, awaited the arrival of the commander-in-chief.
Lee arrived, and a consultation was held. The question now was, the best manner, with a force of about thirty-five thousand, to drive the Federal army, of about one hundred thousand, beyond the Rappahannock.
III.
LEE'S DETERMINATION.
On this night, of the 1st of May, the situation of affairs was strange indeed.
General Hooker had crossed the Rappahannock with a force of one hundred and twenty thousand infantry, and had, without obstruction, secured a position so strong, he declared, that Lee must either "ingloriously fly," or fight a battle in which "certain destruction awaited him." So absolutely convinced, indeed, was the Federal commander, of the result of the coming encounter, that he had jubilantly described the Southern army as "the legitimate property of the Army of the Potomac," which, in the event of the retreat of the Confederates, would "be after them." There seemed just grounds for this declaration, whatever question may have arisen of the good taste displayed by General Hooker in making it. The force opposed to him was in all about forty-seven thousand men, but, as cavalry take small part in pitched battles, Lee's fighting force was only about forty thousand. To drive back forty thousand with one hundred and twenty thousand would not apparently prove difficult, and it was no doubt this conviction which had occasioned the joyous exclamation of General Hooker.
But his own act, and the nerve of his adversary, had defeated every thing. Instead of retreating with his small force upon Richmond, Lee had advanced to accept or deliver battle. This bold movement, which General Hooker does not seem to have anticipated, paralyzed his energies. He had not only crossed the two rivers without loss, but had taken up a strong position, where he could manoeuvre his army perfectly, when, in consequence of Lee's approach with the evident intent of fighting, he had ceased to advance, hesitated, and ended by retiring. This is a fair summary of events up to the night of the 1st of May. General Hooker had advanced boldly; he was now falling back. He had foretold that his adversary would "ingloriously fly;" and that adversary was pressing him closely. The Army of the Potomac, he had declared, would soon be "after" the Army of Northern Virginia; but, from the appearance of things at the moment, the Army of Northern Virginia seemed "after" the Army of the Potomac. We use General Hooker's own phrases—they are expressive, if not dignified. They are indeed suited to the subject, which contains no little of the grotesque. That anticipations and expressions so confident should have been met with a "commentary of events" so damaging, was sufficient, had the occasion not been so tragic, to cause laughter in the gravest of human beings.
Lee's intent was now unmistakable. Instead of falling back from the Rappahannock to some line of defence nearer Richmond, where the force under Longstreet, at Suffolk, might have rejoined him, with other reënforcements, he had plainly resolved, with the forty or fifty thousand men of his command, to meet General Hooker in open battle, and leave the event to Providence. A design so bold would seem to indicate in Lee a quality which at that time he was not thought to possess—the willingness to risk decisive defeat by military movements depending for their success upon good fortune alone. Such seemed now the only deus ex machina that could extricate the Southern army from disaster; and a crushing defeat at that time would have had terrible results. There was no other force, save the small body under Longstreet and a few local troops, to protect Richmond. Had Lee been disabled and afterward pressed by General Hooker, it is impossible to see that any thing but the fall of the Confederate capital could have been the result.
From these speculations and comments we pass to the narrative of actual events. General Hooker had abandoned the strong position in advance of Chancellorsville, and retired to the fastnesses around that place, to receive the Southern attack. His further proceedings indicated that he anticipated an assault from Lee. The Federal troops had no sooner regained the thicket from which they had advanced in the morning, than they were ordered to erect elaborate works for the protection of infantry and artillery. This was promptly begun, and by the next morning heavy defences had sprung up as if by magic. Trees had been felled, and the trunks interwoven so as to present a formidable obstacle to the Southern attack. In front of these works the forest had been levelled, and the fallen trunks were left lying where they fell, forming thus an abatis sufficient to seriously delay an assaulting force, which would thus be, at every step of the necessarily slow advance, under fire. On the roads piercing the thicket in the direction of the Confederates, cannon were posted, to rake the approaches to the Federal position. Having thus made his preparations to receive Lee's attack, General Hooker awaited that attack, no doubt confident of his ability to repulse it.
