"Behind the front line of works, there were some defences in the valley near the creek, not constituting a connecting line, however; and these in turn were succeeded by the second main line of works, which covered the Fairview heights, and were more strongly constructed even than the first." It was at just the time of Rodes's assault, that Birney had received orders to withdraw from his cardinal position at the angle made by Geary and Williams, and to form as a second and third line near the plank road, a duty there was an abundance of troops to fill. He retired, and ployed into brigade columns by regiments, immediately beyond the crest of Fairview hill. Here, placing batteries in position, he shelled the field from which he had just withdrawn. This crest, however, Archer speedily occupied; and on its summit Stuart, with better foresight than Hooker, posted some thirty guns under Walker, which enfiladed our lines with murderous effect during the remainder of the combat of Sunday, and contributed largely to our defeat. The attack of the Confederates was made, "as Jackson usually did, in heavy columns" (Sickles), and was vigorous and effective. According to their own accounts, the onset was met with equal cheerful gallantry. While Archer occupied Hazel Grove, McGowan and Lane assaulted the works held by Williams, carried them with an impetuous rush, and pushed our troops well back. This rapid success was largely owing to a serious breach made in the Union line by the decampment of the Third Maryland Volunteers, a full regiment of Knipe's brigade, which held the right of Williams's division on the plank road. The regiment was composed of new men, no match for Jackson's veterans. They stood as well as raw troops can, in the face of such an onslaught; but after a loss of about a hundred men, they yielded ground, and were too green to rally. Into the gap thus made, quickly poured a stream of Lane's men, thus taking both Berry's and Williams's lines in reverse. The Second Brigade was compelled to change front to meet this new attack: Mott was instantly thrown forward to fill the interval; and after a desperate hand-to-hand struggle he regained the lost ground, and captured eight stands of colors and about a thousand prisoners. This separated Archer from the main line, and took in their turn McGowan and Lane in reverse, precipitately driving them back, and enabling our columns to regain the ground lost by the fierceness of the Confederate inroad. This sally in reverse likewise carried back Lane and Heth, the entire corps having suffered severely from the excellent service of the Federal guns. But the effect on Williams's division of this alternating gain and loss, had been to cause it to waver; while having for an instant captured our works, was encouragement to our foes.
