Assailed in front by superior numbers, and enfiladed by the batteries beyond the Antietam, the Confederate left had everywhere given back. The East Wood was in possession of the enemy. Their right occupied the Miller House; their centre, supported by many batteries, stood across the corn-field; while the left, thrust forward, was actually established on the edge of the West Wood, some five hundred yards to northward of the church. But if Jackson had yielded ground, he had exacted a fearful price. The space between the woods was a veritable slaughter-pen, reeking under the hot September sun, where the blue uniforms lay thicker than the grey. The First Army Corps had been cut to pieces. It had been beaten in fair fight by Jackson’s two divisions, counting at the outset less than half its numbers, and aided only by the cavalry. It had lost in killed and wounded over 100 officers and 2,400 men. Hooker himself had been struck down, and as far as the Antietam the field was covered with his stragglers. The Twelfth Corps had suffered hardly less severely; and Mansfield himself, an old man and a gallant soldier, was dying of his wounds. His batteries indeed remained in action, pouring shot and shell on the West Wood and the Dunkard Church; but his infantry, reduced by more than 1,500 rifles, could do no more than hold their ground.
Nor was the exhaustion of the enemy the only advantage which the Confederates had gained by the slaughter of 4,000 men. The position to which Jackson had retired was more favourable than that from which he had been driven. The line, no longer presenting a weak angle, was almost straight, and no part of the front was open to enfilade. Stuart and his artillery, withdrawn to a more favourable position, secured the left. D. H. Hill on the right, though part of his force had given way, still held the Roulette House and the sunken road, and the troops in the West Wood were well protected from the Northern batteries. The one weak point was the gap occupied by Greene’s Federals, which lay between Grigsby’s regiments in the northern angle of the West Wood and Hood’s division at the Dunkard Church. The enemy, however, showed no signs of making good his opportunity; Early’s brigade was close at hand, and Lee had promised further reinforcements.
A glance southward showed that there was no reason for despair. Over all the field lay the heavy smoke of a great artillery battle. From near the Dunkard Church to the bluff overhanging the Antietam, a distance of two miles, battery on battery was in line. Here were Longstreet’s artillery under Stephen Lee, together with the six-and-twenty guns of Cutts’ reserve battalion, forty-eight guns in all; the divisional batteries of D. H. Hill, and the Washington artillery of New Orleans,[[9]] and in addition to these eighty guns others were in action above the Burnside Bridge. An array even more formidable crowned the opposite crest; but although the Confederate batteries, opposed by larger numbers and heavier metal, had suffered terribly, both in men and in matériel, yet the infantry, the main strength of the defence, was still intact.[[10]] The cliffs of the Red Hill, replying to the rolling thunder of near 800 guns, gave back no echo to the sharper crack of musketry. Save a few skirmishers, who had crossed the Sharpsburg Bridge, not one company of McClellan’s infantry had been sent into action south of the Dunkard Church. Beyond the Antietam, covering the whole space between the river and the hills, the blue masses were plainly to be seen through the drifting smoke; some so far in the distance that only the flash of steel in the bright sunshine distinguished them from the surrounding woods; others moving in dense columns towards the battle:
Standards on standards, men on men;
In slow succession still.
But neither by the Sharpsburg nor yet by the Burnside Bridge had a single Federal regiment crossed the stream; Lee’s centre and right were not even threatened, and it was evident his reserves might be concentrated without risk at whatever point he pleased.
Walker’s division was therefore withdrawn from the right, and McLaws, who had reached Sharpsburg shortly after sunrise, was ordered to the front. G. T. Anderson’s brigade was detached from D. H. Hill; and the whole force was placed at Jackson’s disposal. These fresh troops, together with Early’s regiments, not yet engaged, gave 10,000 muskets for the counterstroke, and had Hooker and Mansfield been alone upon the field the Federal right wing would have been annihilated. But as the Confederate reserves approached the Dunkard Church, Sumner, whom McClellan had ordered to cross Pry’s Bridge with the Second Army Corps, threw three divisions against the West Wood and the Roulette House. In three lines, up the slope from the Antietam, at sixty yards distance and covering a wide front, came Sedgwick on the right, French on the left, and Richardson to the left rear. So orderly was the advance of those 18,000 Northerners, and so imposing their array, that even the Confederate officers watched their march with admiration, and terrible was the shock with which they renewed the conflict.
Sedgwick, emerging from the East Wood, moved directly over the corn-field, crossed the turnpike, and entering the West Wood to northward of the point still held by Greene, swept through the timber, and with a portion of his advanced brigade reached the further edge. Greene, at the same moment, moved upon the Dunkard Church, and Early, who with the fragments of Jones’ division was alone within the wood, marched rapidly in the same direction. Attacked suddenly in flank from behind a ridge of rock Greene’s regiments were driven back; and then Early, observing Sedgwick’s third line pushing across the turnpike, reformed his troops for further action. Greene, for the moment, had been disposed of, but a more formidable attack was threatening. Sedgwick’s 6,000 muskets, confronted only by some 600[[11]] of the Valley soldiers under Grigsby, were thronging through the wood, and a change of front southward would have sent them sweeping down the Confederate line. Early could hardly have withstood their onset; Hood was incapable of further effort, and D. H. Hill was heavily pressed by French. But Jackson’s hand still held the reins of battle. During the fierce struggle of the morning he had remained on the edge of the West Wood, leaving, as was his wont, the conduct of the divisions to his subordinates, but watching his enemy with a glance that saw beyond the numbers arrayed against him. He had already demanded reinforcements from General Lee; and in anticipation of their speedy arrival their orders had been already framed. They had not been called for to sustain his front, or to occupy a new position. Despite the thronging masses of the Federals, despite the fact that his line was already broken, attack, and attack only, was in Jackson’s mind, and the reserves and the opportunity arrived together. A staff officer was dispatched to direct Walker, on the left, to sustain the Texans, to clear the West Wood, and to place a detachment in the gap between the Dunkard Church and the batteries of Colonel Lee;[[12]] while Jackson himself, riding to meet McLaws, ordered him “to drive the enemy back and turn his right.” Anderson’s brigade was sent to support McLaws, and Semmes’ brigade of McLaws’ division was detached to strengthen Stuart.
Forming into line as they advanced, McLaws and Walker, leaving the Dunkard Church on their right, and moving swiftly through the wood, fell suddenly on Sedgwick’s flank. Early joined in the mêlée, and “the result,” says Palfrey, a Northern general who was present on the field, “was not long doubtful. Sedgwick’s fine division was at the mercy of their enemy. Change of front was impossible. In less time than it takes to tell it the ground was strewn with the bodies of the dead and wounded, while the unwounded were moving off rapidly to the north. Nearly 2,000 men were disabled in a moment.”[[13]] And the impetus of the counterstroke was not yet spent. Gordon’s brigade of the Twelfth Corps had been dispatched to Sedgwick’s help, but McLaws had reformed his troops, and after a short struggle the Confederates drove all before them.
Confusion reigned supreme in the Federal ranks. In vain their powerful artillery, firing case and canister with desperate energy, strove to arrest the rush of the pursuing infantry. Out from the West Wood and across the cornfield the grey lines of battle, preceded by clouds of skirmishers, pressed forward without a check, and the light batteries, plying whip and spur, galloped to the front in close support. Hope rose high. The Southern yell, pealing from ten thousand throats, rang with a wild note of anticipated triumph, and Jackson, riding with McLaws, followed with kindling gaze the progress of his counterstroke attack. “God,” he said to his companion, as the shells fell round them and the masses of the enemy melted away like the morning mist, “has been very kind to us this day.”
But the end was not yet. Sedgwick’s brigades, flying to the north-east, rallied under the fire of their batteries, and as the Confederates advanced upon the East Wood, they found it already occupied by a fresh brigade. Smith’s division of the Sixth Corps had been sent forward by McClellan to sustain the battle, and its arrival saved his army from defeat. Once more the corn-field became the scene of a furious struggle, the Southerners fighting for decisive victory, the Federals for existence. So impetuous was McLaws’ attack that the regiments on his left, although checked by the fences, drove in a battery and dashed back the enemy’s first line; but the weight of the artillery in front of the North Wood, supported by a portion of Smith’s division, prevented further advance, and a Federal brigade, handled with rare judgment, rushed forward to meet the assailants in the open. Sharp was the conflict, for McLaws, a fine soldier, as daring as he was skilful, strove fiercely to complete the victory; but the fight within the woods and the swift pursuit had broken the order of his division. Brigade had mingled with brigade, regiment with regiment. There were no supports; and the broken ranks, scourged by the terrible cross-fire of many batteries, were unable to withstand the solid impact of the Federal reserve. Slowly and sullenly the troops fell back from the deadly strife. The enemy, no less exhausted, halted and lay down beyond the turnpike; and while the musketry once more died away to northward of the Dunkard Church, Jackson, rallying his brigades, re-established his line along the edge of the West Wood.
