The three Confederate lines of attack had soon, as on yesternight, become one, as each pushed forward to sustain the other. The enemy "pressed forward in crowds rather than in any regular formation" (Sickles); but the momentum of these splendid troops was well-nigh irresistible. Nichols's brigade of Trimble's division, and Iverson's and Rodes's of Rodes's division, pressed forward to sustain the first line on the north of the road, and repel the flank attack, constantly renewed by Berry. Another advance of the entire line was ordered. Rodes led his old brigade in person. The Confederates seemed determined, for Jackson's sake, to carry and hold the works which they had twice gained, and out of which they had been twice driven; for, with "Old Jack" at their head, they had never shown a sterner front.

Now came the most grievous loss of this morning's conflict. Gallant Berry, the life of his division, always in the hottest of the fire, reckless of safety, had fallen mortally wounded, before Ward's brigade could reach his line. Gen. Revere assumed command, and, almost before the renewal of the Confederate attack, "heedless of their murmurs," says Sickles's report, "shamefully led to the rear the whole of the Second Brigade, and portions of two others, thus subjecting these proud soldiers, for the first time, to the humiliation of being marched to the rear while their comrades were under fire. Gen. Revere was promptly recalled with his troops, and at once relieved of command." Revere certainly gives no satisfactory explanation of his conduct; but he appears to have marched over to the vicinity of French of the Second Corps, upon the White House clearing, and reported to him with a large portion of his troops. Revere was subsequently courtmartialled for this misbehavior, and was sentenced to dismissal; but the sentence was revoked by the President, and he was allowed to resign.

Col. Stevens was speedily put in command in Revere's stead; but he, too, soon fell, leaving the gallant division without a leader, nearly half of its number off the field, and the remainder decimated by the bloody contest of the past four hours. Moreover, Gen. Hays, whose brigade of French's division had been detached in support of Berry, where it had done most gallant work, was at the same time wounded and captured by the enemy.

It was near eight o'clock. The artillery was quite out of ammunition, except canister, which could not be used with safety over the heads of our troops. Our outer lines of breastworks had been captured, and were held by the enemy. So much as was left of Berry's division was in absolute need of re-forming. Its supports were in equally bad plight. The death of Berry, and the present location of our lines in the low ground back of the crest just lost, where the undergrowth was so tangled and the bottom so marshy, that Ward, when he marched to Berry's relief, had failed to find him, obliged the Federals to fall back to the Fairview heights, and form a new line at the western edge of the Chancellor clearing, where the artillery had been so ably sustaining the struggle now steadily in progress since daylight. Sickles himself supervised the withdrawal of the line, and its being deployed on its new position.

The receding of the right of the line also necessitated the falling-back of Williams. The latter officer had, moreover, been for some time quite short of ammunition; and though Graham had filled the place of a part of his line, and had held it for nearly two hours, repeatedly using the bayonet, Williams was obliged to give way before Stuart's last assault. But Graham was not the man readily to accept defeat; and, as Williams's line melted away, he found himself isolated, and in great danger of being surrounded. Gen. Birney fortunately became aware of the danger before it was too late; and, hastily gathering a portion of Hayman's brigade, he gallantly led them to the charge in person; and, under cover of this opportune diversion, Graham contrived to withdraw in good order, holding McGowan severely in check.

The Union troops now establish their second line near Fairview. The Confederates' progress is arrested for the nonce. It is somewhat after eight A.M. A lull, premonitory only of a still fiercer tempest, supervenes.

But the lull is of short duration. Re-forming their ranks as well as may be on the south of the road, the Confederates again assault the Union second line, on the crest at Fairview. But the height is not readily carried. The slope is wooded, and affords good cover for an assault. But the artillery on the summit can now use its canister; and the Union troops have been rallied and re-formed in good order. The onset is met and driven back, amid the cheers of the victorious Federals.

Nor are Stuart's men easily discouraged. Failure only seems to invigorate these intrepid legions to fresh endeavors. Colston's and Jones's brigades, with Paxton's, Ramseur's, and Doles' of the third line, have re-enforced the first, and passed it, and now attack Williams with redoubled fury in his Fairview breastworks, while Birney sustains him with his last man and cartridge. The Confederate troops take all advantage possible of the numerous ravines in our front; but the batteries at Fairview pour a heavy and destructive fire of shell and case into their columns as they press on. Every inch of ground is contested by our divisions, which hold their footing at Fairview with unflinching tenacity.

Meanwhile Doles, moving under cover of a hill which protects him from the Federal batteries, and up a little branch coming from the rear of Fairview, takes in reverse the left of Williams's line, which has become somewhat separated from Geary, (whose position is thus fast becoming untenable,) moves up, and deploys upon the open ground at Chancellorsville. But he finds great difficulty in maintaining his footing, and would have at once been driven back, when Paxton's (old Stonewall) brigade comes up to his support on the double-quick. Jackson's spirit for a while seems to carry all before it; the charge of these two brigades against our batteries fairly bristles with audacity; but our guns are too well served, and the gallant lines are once again decimated and hustled back to the foot of the crest.

The seizure of Hazel Grove, from which Sickles had retired, had now begun to tell against us. It had enabled the Confederates not only to form the necessary junction of their hitherto separated wings, but to enfilade our lines in both directions. The artillery under Walker, Carter, Pegram, and Jones, was admirably served, and much better posted than our own guns at Fairview. For this height absolutely commanded the angle made by the lines of Geary and Williams, and every shot went crashing through heavy masses of troops. Our severest losses during this day from artillery-fire emanated from this source, not to speak of the grievous effect upon the morale of our men from the enfilading missiles.
