The Federal gunners, striving valiantly to cover the retreat of their shattered infantry, met the advance of the Southerners with a rapid fire. Pope and McDowell exerted themselves to throw a strong force on to the heights above Bull Run; and the two brigades upon the left, Warren’s and Alexander’s, already overlapped, made a gallant effort to gain time for the occupation of the new position.
But the counterstroke of Lee was not to be withstood by a few regiments of infantry. The field of Bull Run had seen many examples of the attack as executed by indifferent tacticians. At the first battle isolated brigades had advanced at wide intervals of time. At the second battle the Federals had assaulted by successive divisions. Out of 50,000 infantry, no more than 20,000 had been simultaneously engaged, and when a partial success had been achieved there were no supports at hand to complete the victory. When the Confederates came forward it was in other fashion; and those who had the wit to understand were now to learn the difference between mediocrity and genius, between the half-measures of the one and the resolution of the other. Lee’s order for the advance embraced his whole army. Every regiment, every battery, and every squadron was employed. No reserves save the artillery were retained upon the ridge, but wave after wave of bayonets followed closely on the fighting-line. To drive the attack forward by a quick succession of reinforcements, to push it home by weight of numbers, to pile blow on blow, to keep the defender occupied along his whole front, and to provide for retreat, should retreat be necessary, not by throwing in fresh troops, but by leaving the enemy so crippled that he would be powerless to pursue—such were the tactics of the Confederate leader.
The field was still covered with Porter’s and Hatch’s disordered masses when Lee’s strong array advanced, and the sight was magnificent. As far as the eye could reach the long grey lines of infantry, with the crimson of the colours gleaming like blood in the evening sun, swept with ordered ranks across the Groveton valley. Batteries galloped furiously to the front; far away to the right fluttered the guidons of Stuart’s squadrons, and over all the massed artillery maintained a tremendous fire. The men drew fresh vigour from this powerful combination. The enthusiasm of the troops was as intense as their excitement. With great difficulty, it is related, were the gunners restrained from joining in the charge, and the officers of the staff could scarcely resist the impulse to throw themselves with their victorious comrades upon the retreating foe.
The advance was made in the following order:
Wilcox’ division, north of the turnpike, connected with Jackson’s right. Then came Evans, facing the two brigades which formed the Federal left, and extending across the turnpike. Behind Evans came Anderson on the left and Kemper on the right. Then, in prolongation of Kemper’s line, but at some interval, marched the division of D. R. Jones, flanked by Stuart’s cavalry, and on the further wing, extending towards Bull Run, were Starke, Lawton, and A. P. Hill. 50,000 men, including the cavalry, were thus deployed over a front of four miles; each division was formed in at least two lines; and in the centre, where Anderson and Kemper supported Evans, were no less than eight brigades one in rear of the other.
The Federal advanced line, behind which the troops which had been engaged in the last attack were slowly rallying, extended from the Groveton wood to a low hill, south of the turnpike and east of the village. This hill was quickly carried by Hood’s brigade of Evans’s division. The two regiments which defended it, rapidly outflanked, and assailed by overwhelming numbers, were routed with the loss of nearly half their muster. Jackson’s attack through the Groveton wood was equally successful, but on the ridge in rear were posted the regulars under Sykes; and, further east, on Buck Hill, had assembled the remnants of four divisions.
Outflanked by the capture of the hill upon their left, and fiercely assailed in front, Sykes’s well-disciplined regiments, formed in lines of columns and covered by a rear-guard of skirmishers, retired steadily under the tremendous fire, preserving their formation, and falling back slowly across Young’s Branch. Then Jackson, reforming his troops along the Sudley road, and swinging round to the left, moved swiftly against Buck Hill. Here, in addition to the infantry, were posted three Union batteries, and the artillery made a desperate endeavour to stay the counterstroke.
But nothing could withstand the vehement charge of the Valley soldiers. “They came on,” says the correspondent of a Northern journal, “like demons emerging from the earth.” The crests of the ridges blazed with musketry, and Hill’s infantry, advancing in the very teeth of the canister, captured six guns at the bayonet’s point. Once more Jackson reformed his lines; and, as twilight came down upon the battle-field, from position after position, in the direction of the Stone Bridge, the division of Stevens, Ricketts, Kearney, and Hooker, were gradually pushed back.
On the Henry Hill, the key of the Federal position, a fierce conflict was meanwhile raging. From the high ground to the south Longstreet had driven back several brigades which, in support of the artillery, Sigel and McDowell had massed upon Bald Hill. But this position had not been occupied without a protracted struggle. Longstreet’s first line, advancing with over-impetuosity, had outstripped the second; and before it could be supported was compelled to give ground under the enemy’s fire, one of the brigades losing 62 officers and 560 men. Anderson and Kemper were then brought up; the flank of the defenders was turned; a counterstroke was beaten back, ridge after ridge was mastered, the edge of every wood was stormed; and as the sun set behind the mountains Bald Hill was carried. During this fierce action the division of D. R. Jones, leaving the Chinn House to the left, had advanced against the Henry Hill.
6 p.m. On the very ground which Jackson had held in his first battle the best troops of the Federal army were rapidly assembling. Here were Sykes’ regulars and Reynolds’ Pennsylvanians; where the woods permitted batteries had been established; and Porter’s Fifth Army Corps, who at Gaines’ Mill and Malvern Hill had proved such stubborn fighters, opposed a strong front once more to their persistent foes.
