Hooker and Sickles have both stated that the plan of the former was to allow this movement of Jackson's to develop itself: if it was a retreat, to attack the column at the proper time; if a tactical flank movement, to allow it to be completed, and then thrust himself between the two wings of Lee's army, and beat them in detail. This admirable generalization lacked the necessary concomitant of intelligent and speedy execution.

Now, Hooker had his choice between two theories of this movement of Jackson. It was a retreat from his front, either because Lee deemed himself compromised, or for the purpose of making new strategic combinations; or it was the massing of troops for a flank attack. It could mean nothing else. Let us, then, do Hooker all the justice the situation will allow.

All that had occurred during the day was fairly explainable on the former hypothesis. If Jackson was passing towards Culpeper, he would naturally send flanking parties out every road leading from the one his own columns were pursuing, towards our lines, for strictly defensive purposes. The several attacks of the day might have thus occurred. This assumption was quite justifiable.

And this was the theory of Howard. He knew that Hooker had all the information obtained along the entire line, from prisoners and scouts. He naturally concluded, that if there was any reasonable supposition that an attack from the west was intended, Hooker would in some way have notified him. But, far from doing this, Hooker had inspected and approved his position, and had ordered Howard's reserve away. To be sure, early in the morning, Hooker had told him to guard against an attack on the right: but since then circumstances had absolutely changed; Barlow had been taken from him, and he conjectured that the danger of attack had passed. How could he assume otherwise?

Had he suspected an attack down the pike, had he received half an hour's warning, he could, and naturally would, assuming the responsibility of a corps commander, have changed front to rear so as to occupy with his corps the line along the east side of the Dowdall's clearing, which he had already intrenched, and where he had his reserve artillery. He did not do so; and it is more easy to say that he was to blame, than to show good cause for the stigma cast upon him for the result of this day.

However much Hooker's after-wit may have prompted him to deny it, his despatch of 4.10 P.M., to Sedgwick, shows conclusively that he himself had adopted this theory of a retreat. "We know that the enemy is flying," says he, "trying to save his trains. Two of Sickles's divisions are among them."

And it is kinder to Hooker's memory to assume that he did not apprehend a flank attack on this evening. If he did, his neglect of his position was criminal. Let us glance at the map.

We know how the Eleventh Corps lay, its reserve removed, with which it might have protected a change of front, should this become necessary, and itself facing southerly. What was on its left, to move up to its support in case of an attack down the pike? Absolutely not a regiment between Dowdall's and Chancellorsville, and near the latter place only one division available. This was Berry's, still luckily massed in the open north of headquarters. And to Sickles's very deliberate movement alone is due the fact that Berry was still there when the attack on Howard burst; for Sickles had bespoken Berry's division in support of his own advance just at this juncture.

Birney, who was the prop of Howard's immediate left, had been advanced nearly two miles through the thickets to the south to attack an imaginary enemy. Whipple had followed him. Of Slocum's corps, Williams had been sent out "two or three miles," to sweep the ground in his front, and Geary despatched down the plank road "for the purpose of cutting off the train of the enemy, who was supposed to be in retreat towards Gordonsville." To oppose the attack of a column of not far from twenty-five thousand men, there was thus left a brigade front of four small regiments, and the flank of a corps of eight thousand men more, without reserves, and with no available force whatever for its support, should it be overwhelmed.

Is any criticism needed upon this situation? And who should be responsible for it?

In a defensive battle it is all-important that the general in command should hold his troops well in hand, especially when the movements of the enemy can be concealed by the terrain. The enemy is allowed his choice of massing for an attack on any given point: so that the ability to concentrate reserve troops on any threatened point is an indispensable element of safety. It may be assumed that Hooker was, at the moment of Jackson's attack, actually taking the offensive. But on this hypothesis, the feebleness of his advance is still more worthy of criticism. For Jackson was first attacked by Sickles as early as nine A.M.; and it was six P.M. before the latter was ready to move upon the enemy in force. Such tardiness as this could never win a battle.

While all this had been transpiring on the right, Lee, to keep his opponent busy, and prevent his sending re-enforcements to the flank Jackson was thus threatening, had been continually tapping at the lines in his front. But, owing to the small force left with him, he confined this work to Hooker's centre, where he rightly divined his headquarters to be. About seven A.M. the clearing at Chancellorsville was shelled by some of Anderson's batteries, obliging the trains there parked to go to the rear into the woods.

Hancock states that the enemy frequently opened with artillery, and made infantry assaults on his advanced line of rifle-pits, but was always handsomely repulsed. "During the sharp contests of that day, the enemy was never able to reach my principal line of battle, so stoutly and successfully did Col. Miles (who commanded the advanced line) contest the ground."

Col. Miles says his line was constantly engaged skirmishing with the enemy during the day. At about three P.M. the Confederates massed troops in two columns, one on each side the road, flanked by a line some eight hundred yards long, in the woods. An impetuous charge was made to within twenty yards of the abattis, but it was baffled by our sturdy front.

Sickles, then still in reserve, had made a reconnoissance early on Saturday, in Hancock's front, with the Eleventh Massachusetts and Twenty-sixth Pennsylvania Volunteers, covered by some sharpshooters; had driven in the enemy's pickets, and found him, to all appearances, in force. This was Anderson's line.

The Twelfth Corps had also made a reconnoissance down the plank road later in the day, but with no immediate results.

All that was accomplished was a mere feeling of the other's lines by either force. Hooker vainly endeavored to ascertain Lee's strength at various places in his front. Lee, to good purpose, strove to amuse Hooker by his bustle and stir, to deceive him as to the weakness of his force, and to gain time.

During the afternoon of Saturday, Hooker had a rare chance of redeeming his error made, the day before, in withdrawing from the open country to the Wilderness, and of dealing a fatal blow to his antagonist. He knew that Jackson, with twenty-five thousand men, was struggling through difficult roads towards his right. Whatever his object, the division of Lee's forces was a fact. He knew that there could be left in his front not more than an equal number. It was actually less than eighteen thousand men; but Hooker, with his knowledge of Lee's strength, could not estimate it at more than twenty-five thousand by any calculation he could make. Himself had over seventy thousand men in line, and ready to mass on any given point. He ought to have known that Lee was too astute a tactician seriously to attack him in front, while Jackson was manoeuvring to gain his right. And all Lee's conduct during the day was palpable evidence that he was seeking to gain time.

However much Hooker may have believed that Jackson was retreating, he was bound to guard against the possibility of an attack, knowing as he did Jackson's whereabouts and habit of rapid mystery. Had he thrown the entire Eleventh Corps en potence to his main line, as above indicated, to arrest or retard an attack if made; had he drawn troops from Meade on the extreme left, where half an hour's reconnoitring would have shown that nothing was in his front, and from Couch's reserves in the centre; had he thrown heavy columns out where Birney was, to prevent the re-union of Jackson and Lee, and to make a determined attack upon the latter's left while Hancock pressed him in front,—half the vigor displayed in the early days of this movement would have crushed the Army of Northern Virginia beyond recovery for this campaign. Lee's only salvation would have lain in instant withdrawal from our front, and a retreat towards Gordonsville to re-unite with his lieutenant.

However he might have disposed his forces for an attack on Saturday afternoon, he could have committed no mistake as great as the half-way measures which have been narrated. And if the heavy fighting of Sunday had been done the day before with any thing like the dispositions suggested, it could have scarcely failed of brilliant success for the Army of the Potomac.

But six o'clock came: Hooker still lay listlessly awaiting an attack, with his forces disjointedly lodged, and with no common purpose of action; and Jackson had gathered for his mighty blow.

It is but fair to give weight to every circumstance which shall moderate the censure attributable to Hooker for his defeat in this campaign. Early in the morning, after his inspection of the lines on the right, which was made with thoroughness, and after receipt of the first news of the movement of troops across our front, Hooker issued the following circular:—

MAJOR-GEN. SLOCUM AND MAJOR-GEN. HOWARD.

I am directed by the major-general commanding to say that the disposition you have made of your corps has been with a view to a front attack by the enemy. If he should throw himself upon your flank, he wishes you to examine the ground, and determine upon the positions you will take in that event, in order that you may be prepared for him in whatever direction he advances. He suggests that you have heavy reserves well in hand to meet this contingency. The right of your line does not appear to be strong enough. No artificial defences worth naming have been thrown up; and there appears to be a scarcity of troops at that point, and not, in the general's opinion, as favorably posted as might be.

We have good reason to suppose that the enemy is moving to our right. Please advance your pickets for purposes of observation as far as may be, in order to obtain timely information of their approach.

Although addressed to Slocum as well as Howard, this order scarcely applied with much force to the former, who occupied the right centre of the army, with Birney lying between him and the Eleventh Corps. Howard carried out his part of these instructions as well as circumstances allowed. He posted Barlow's brigade, his largest and best, on the Buschbeck line, in position for a general reserve for the corps, and took advantage of the ground in a manner calculated to strengthen his flank, and to enable it to cover a change of front if necessary; he placed his reserve artillery on the right of the rifle-pits running across the road at Dowdall's; he located several regiments on Dowdall's clearing so as to wheel to the west or south as might be required; Major Hoffman was set to work, and spent the entire day locating and supervising the construction of field-works; and generally, Howard disposed the forces under his command after a fashion calculated to oppose a stubborn resistance to attacks down the pike, should they be made.

Later on in the day, we have seen how Hooker's aide, Capt. Moore, ordered this brigade of Barlow's away from its all-important position. We have seen Hooker's dispositions of the Third and Twelfth Corps. We have seen Hooker's 4.10 P.M. order to Sedgwick. No room is left to doubt that Hooker's opinion, if he had any, underwent a change after issuing these instructions, and that he gave up the idea of an attack upon the right. His dispositions certainly resulted in convincing Howard that he had done so.

But suppose Hooker still remained of the same opinion during the afternoon, was the issue of this circular in the morning enough? If he supposed it probable that the enemy would strike our right, was it not the duty of the commanding general, at least to see that the threatened flank was properly protected,—that the above order was carried out as he intended it should be? No attack sufficient to engross his attention had been made, or was particularly threatened elsewhere; and a ten-minutes' gallop would bring him from headquarters to the questionable position. He had some excellent staff-officers—Gen. Warren among others—who could have done this duty; but there is no evidence of any one having been sent. Gen. Howard, in fact, states that no inspection by, or by the order of, Gen. Hooker was made during the day, after the one in the early morning.

It may be alleged that Hooker had desired to draw in the extended right the evening before, and had yielded only to the claim that that position could be held against any attack coming from the front. This is true. But when half his enemy's forces, after this disposition was made, are moved to and massed on his right, and have actually placed themselves where they can take his line in reverse, is it still fair to urge this plea? Hooker claims that his "instructions were utterly and criminally disregarded." But inasmuch as common-sense, not to quote military routine, must hold him accountable for the removal of Barlow (for how can a general shelter himself from the consequences of the acts of his subordinates, when these acts are in pursuance of orders received from his own aide-de-camp?), and himself acknowledges the disposition made of Sickles and Slocum, can the facts be fairly said to sustain the charge? There was, moreover, so much bitterness exhibited after this campaign, that, had the facts in the slenderest degree warranted such action, formal charges would assuredly have been brought against Howard and his division commanders, on the demand alike of the commander-in-chief and a disappointed public.
