As soon as Crook was fairly across the Red Bud, his movement silenced the battery on the left bank that had been enfilading Emory's line, and this served to tell Emory that Crook was in place and at work. Averell and Merritt could be plainly seen surging up the valley road far in Gordon's left and rear, furiously driving before them the main body of Fitzhugh Lee's cavalry. About four o'clock the cheers of Duval's men beyond the Red Bud served as the signal for Thoburn, and now as Crook moved forward, sweeping everything before him, from right to left the whole army responded to the impulse. To meet Thoburn, Breckinridge placed Wharton in position at right angles with Gordon and with the valley road. Duval, having easily driven before him everything on the left bank of the Red Bud, waded through the marsh on his left, crossed the run, and united with Thoburn. Then Crook, with a sudden and irregular but curiously effective half-wheel to the left, fell vigorously upon Gordon, and Torbert coming on with great impetuosity at the same instant, the weight was heavier than the attenuated lines of Breckinridge and Gordon could bear. Early saw his whole left wing give back in disorder, and as Emory and Wright pressed hard, Rodes and Ramseur gave way, and the battle was over. All that remained to Early was to make good his retreat, now seriously compromised by the steady progress of Wilson toward and at last upon the Millwood road. Early vainly endeavored to reunite his shattered fragments behind the lines constructed in the former campaigns for the defence of Winchester on the east. About five o'clock Torbert and Crook, fairly at right angles to the first line of battle, covered Winchester on the north from the rocky ledges that lie to the eastward of the town nearly to the first position of Braxton's guns. Thence Wright extended the line at right angles with Crook and parallel with the valley road, while Sheridan drew out Emory, who was naturally displaced by these converging movement, and sent him to extend Wright's line toward the south. The disorderly retreat of Early's men once begun, there was no staying it. Torbert pursued the fugitives to Kernstown, where Ramseur faced about, but Sheridan, mindful that his men had been on their feet since two o'clock in the morning, many of them since one, and had in the meantime fought with varying success a long and hard fight ending in a great victory, made no attempt to send his infantry after the flying enemy.
