When his troops had been summarily brought to a standstill by Berry's firm ranks and the heavy artillery fire, Jackson determined to withdraw his first and second lines to Dowdall's clearing to reform, and ordered A. P. Hill forward to relieve them.

While this manoeuvre, rendered extremely difficult by the nature of the woods in which the fighting had been done, but which Hooker was in no condition to interfere with, was in progress, Sickles and Pleasonton, whose position was considerably compromised, sought measures to re-establish communication with the headquarters of the army.

Sickles despatched Col. Hart, with a cavalry escort, to Hooker, bearing a detailed statement of his situation. This officer experienced no little difficulty in reaching Chancellorsville. The roads being in possession of the enemy, he was forced to make his way through the woods and ravines. But after the lapse of a number of hours he succeeded in his mission, and brought back word to hold on to the position gained. Sickles had so advised, and had, moreover, requested permission to make a night attack, to recover some guns, caissons, and Whipple's ammunition-train, which had been left in the woods in Sickles's front, and to enable him to join his right to Slocum's new line, thrown out in prolongation of Berry.

It will be observed that Sickles was now facing northerly, and that his rear had no obstacle on which to rest, so as to save him from the attack of Lee, had the latter been aware of the weakness of his position.

In view of this fact, a move was made somewhat to his right, where a crest was occupied near Hazel Grove. Here, says Pleasonton, "with the support of Gen. Sickles's corps we could have defeated the whole rebel army." It was clearly a strong position; for it is thus referred to by Stuart, after our troops had been next day withdrawn: "As the sun lifted the mist that shrouded the field, it was discovered that the ridge on the extreme right was a fine position for concentrating artillery. I immediately ordered thirty pieces to that point. The effect of this fire upon the enemy's batteries was superb." Its possession by the Confederates did, in fact, notably contribute to the loss of the new lines at Chancellorsville in Sunday morning's action.

From this position, at precisely midnight, Sickles made a determined onslaught upon the Confederate right. It was clear, full moonlight, and operations could be almost as well conducted as during the daytime, in these woods.

Birney stationed Ward in the first line, and Hays in the second, one hundred yards in the rear. The regiments moved by the right of companies, with pieces uncapped, and strict orders to rely solely upon the bayonet. On the road from the Furnace north, parallel to which the columns moved, the Fortieth New York, Seventeenth Maine, and Sixty-Third Pennsylvania Volunteers pushed in, in columns of companies at full distance.

Berry had been notified to sustain this attack by a movement forward from his lines, if it should strike him as advisable.

The attack was made with consummate gallantry. Sickles states that he drove the enemy back to our original lines, enabling us for the moment to re-occupy the Eleventh Corps rifle-pits, and to re-capture several pieces of artillery, despite the fire of some twenty Confederate guns which had been massed at Dowdall's.

Thus attacked in flank, though the Confederate right had been refused at the time of Pleasonton's fight, and still remained so, Hill's line replied by a front movement of his left on Berry, without being able, however, to break the latter's line.

Slocum states that he was not aware that this advance was to be made by Sickles across his front. Imagining it to be a movement by the enemy on Williams, he ordered fire to be opened on all troops that appeared, and fears "that our losses must have been severe from our own fire." Williams, however, does not think so much damage was done, and alleges that he himself understood what the movement was, without, however, quoting the source of his information.

The Confederate reports state that this attack was met and repulsed by the Eighteenth, Twenty-eighth, and Thirty-third North-Carolina regiments, with small difficulty or loss.

It is, however, probable that these as much underrate the vigor and effect of the attack, as Sickles may overstate it. It is not impossible that some portion of the Eleventh Corps position was actually reached by these columns. The road down which the movement was made strikes the plank road but a short distance east of the position of Buschbeck's line. This ground was not held in force by Jackson's corps at the moment, and it was not difficult for Sickles to possess himself temporarily of some portion of that position. But it must have been a momentary occupation.

Birney retired to Hazel Grove after this sally, having recovered part of Whipple's train, and one or two guns.

There can be found in the Confederate and Union reports alike, numerous statements which are not sustained by other testimony. As a sample, Gen. Lane of A. P. Hill's division states that a Lieut. Emack and four men captured an entire Pennsylvania regiment, under Lieut.-Col. Smith. The nearest approach to this is found in the capture of Col. Mathews and two hundred men of the One Hundred and Twenty-Eighth Pennsylvania, while Williams was moving by his left to regain his old ground. But it is highly probable that it required more than five men to effect the capture.

A wise rebuke of careless statements in official reports is found in the following indorsements on a report made of the operations of the One Hundred and Fourteenth Pennsylvania:—

In forwarding this report, which I do merely as a matter of duty, it is incumbent upon me to say that it is a complete romance from beginning to end. Col. Collis has had his attention called to these errors, but has refused to correct them.

This paper is forwarded with attention called to Brig.-Gen. Graham's indorsement. The officer is under arrest on charges of misbehavior before the enemy.
