on the pike to the west end of Berryville Canyon, where the Virginians fled past pickets from the 23rd North Carolina Infantry Regiment. The North Carolinians fell back several hundred yards (about 275 m) beyond the west end of Berryville Canyon, and joined the rest of their brigade as their commander sent a courier to division commander Major General Stephen Dodson Ramseur. McIntosh attacked the high ground with his lead regiments armed with repeating rifles. Lieutenant Colonel William P. Brinton, commanding the 18th Pennsylvania Cavalry Regiment, led a charge that captured an important Confederate breastworks. The Confederates regrouped and recaptured the breastworks, shooting Brinton's horse and capturing Brinton, who escaped that evening. McIntosh personally led men from the 2nd Ohio Cavalry Regiment, some dismounted, and again captured the breastworks. Wilson reported that with the breastworks "securely in our possession, the infantry were enabled to form at leisure and to deliver battle with every prospect of success." The fighting reached a stalemate as Ramseur rallied his men and brought in reinforcements, while Wilson deployed his artillery. His other brigade, commanded by Brigadier General George H. Chapman, deployed to the north along a line that would eventually be occupied by the XIX Corps. Sheridan rode behind Wilson's Cavalry Division, leaving Wright to direct the movement of 24,000 infantry men from the VI and XIX Corps using the Berryville Pike from Berryville to Winchester. Wright's VI Corps, who arrived at the beginning of Berryville Canyon about 5:00am, moved a baggage train and artillery into the narrow canyon before the fighters from Emory's XIX Corps could enter. A combination of ambulances returning from the front with McIntosh's wounded plus Wright's wagons moving toward the front caused a massive traffic jam. Emory's XIX Corps did not enter the canyon until 9:00am. Merritt's 1st Cavalry Division advances from northeast Merritt's 1st Cavalry Division also began moving at 2:00am on September 19. The division left camp from Summit Point, West Virginia, which was on the Winchester and Potomac Railroad about north of Berryville. At the time, the railroad was out-of-service. Merritt and Cavalry Corps commander Torbert rode with Colonel Charles R. Lowell and his Reserve Brigade, which led the advance. The Second Brigade, led by Brigadier General Thomas Devin, covered the rear. The First Brigade, led by Brigadier General George Armstrong Custer, was about north and advanced independently. The brigades reached fords on Opequon Creek before daybreak,
