The assault of the rebels fell upon the green troops of the Third division, who, seized with consternation, fled in confusion without attempting resistance. General Seymour whose gallant conduct up to this time had won for him the admiration of all, made desperate attempts to rally his panic-stricken brigade and refused to go to the rear with them. While thus striving vainly to restore order to his shattered command, rushing to the front and attempting by his own manner to inspire courage in his men, he was surrounded by the enemy and captured. He had but just returned from the rebel prisons where he had been since the unfortunate battle of Olustee.

The hasty flight of the Third division opened the flank and rear of the First division to the charge of the rebels, who now rushed on with redoubled fury and with demoniac yells, carrying everything before them. The First division fell back, but not in the disorder and confusion of the other. General Shaler, with a large part of his brigade, which held that part of the line joining the Third division, was captured while vainly striving to resist the onset of the rebel forces.

The regiments of our Third brigade were forced from the rifle pits, leaving the Seventy-seventh regiment and a part of the Forty-third alone contending the ground, exposed to a galling fire on front, flank and rear. The gallant regiments remained in the breastworks, pouring their fire into the enemy's ranks until ordered to withdraw, to save themselves from capture.

The right wing, if not the whole army, was now in danger. It was at such times that the great spirit of the noble Sedgwick rose to the control of events. It seemed to require adversity to bring out all the grand qualities of his nature. We had witnessed his imperturbable bravery and determination on the retreat to Banks' Ford, his unsurpassed heroism at Antietam, when he kept the field after he was thrice wounded, was familiar to the nation, and now we were to see another manifestation of his indomitable courage.

Rushing here and there, regardless of personal safety, he faced the disordered mass of fugitives of the Third division, and with threats and entreaties prevailed upon them to halt; then turning to the veterans of the First division, he shouted to them to remember the honor of the old Sixth corps. That was an irresistible appeal, and the ranks of the First division and of our Third brigade were formed along the turnpike, which was at right angles to our former position. The corps now charged upon the exultant foe, and forced them back until our breastworks were recaptured; but our flank was too much exposed, and again the enemy charged upon our front and flank, forcing the corps to wheel back to the turnpike, where it had first rallied.

General Sedgwick now ordered another charge, and bravely the men rushed forward, ready to obey any order from the revered lips of "Uncle John." The enemy was again forced back, and again the corps occupied the breastworks. It was now dark, but the roar of musketry mingled with the deep toned artillery shook the ground, and the dense forest was lighted by the scores of thousands of flashing rifles which sent death to unseen foes.

The corps had not recovered its line of works without sacrifice, for the ground in our rear was covered with our fallen comrades, while many more had been captured by the enemy. But we were now able to hold the ground. The temporary disorder had arisen, and had been mostly confined to the new troops, and even these, when rallied from their momentary confusion, had fought with heroic valor. Although, for a time, forced back by the surprise of the rebel onset, the old troops of the corps had shown no want of courage. The Sixth corps proper had not lost its pristine glory. Something of a panic had been created among the teamsters in the rear, and before dark the trains were hurrying toward Chancellorsville.

Leaving the excitement of the battle, let us now turn where the results of this carnage are seen in their sober reality. While we stand in line of battle we see little of the frightful havoc of war. The wounded drop about us, but, except those left on disputed ground and unable to crawl away, they are carried instantly to the rear. The groans and cries of the wounded and dying, of which we so often read as filling up the grand discord of sounds on the battle-field, are things scarcely known in actual war. Rarely, as in the present battles, wounded men, unable to get away, are left between the lines in such numbers that, when the musketry dies away, their groans become heart-rending. But this is not usual.

But at the field hospitals, the work of destruction is seen in all its horrors. There, wounded men by thousands are brought together, filling the tents and stretched upon every available spot of ground for many rods around. Surgeons, with never tiring energy, are ministering to their wants, giving them food, dressing their wounds or standing at the operating table removing the shattered fragments of limbs. Men wounded in every conceivable way, men with mutilated bodies, with shattered limbs and broken heads, men enduring their injuries with heroic patience, and men giving way to violent grief, men stoically indifferent, and men bravely rejoicing that it is only a leg. To all these the surgeons are to give such relief as lies in their power, a task the very thoughts of which would overcome physicians at home, but upon which the army surgeon enters with as much coolness and confidence as though he could do it all at once. He has learned to do what he can. Contenting himself with working day and night without respite, and often without food, until, by unremitting but quiet toil, the wants of all are relieved. No class of men in the army perform so great labors with so little credit as the surgeons.

Lest the author should be accused of undue partiality for his own staff, he will quote the words of an unprejudiced witness, who, in speaking of the labor, the anxiety and the responsibility imposed upon the surgeons after a great battle, says:
