withdraw. Both Upton and Crook tried to persuade two regiments from the XIX Corps to attack the corner of the Confederate position, but the regiments refused because Emory ordered the XIX Corps to not go beyond the Second Woods. Upton then sent Colonel Ranald S. Mackenzie and the 2nd Connecticut Heavy Artillery Regiment past the XIX Corps regiments to a rail fence where they fired upon Gordon's right flank. They received unexpected assistance when Brigadier General James W. McMillan from Dwight's 1st Division of the XIX Corps arrived with the 160th New York Infantry Regiment, and deployed on Mackenzie's right flank. This caused Gordon's men to retreat, and Thoburn's men leapt the wall and attacked. Crook's entire army came forward, and they joined Upton's right—which also had the effect of sealing the XIX Corps out of the battle. Battle's (Rodes') Division then withdrew toward Winchester in disorder, and Upton pushed the rest of his division forward from the left. His obstacle was the Baker House, which was on high ground containing Grimes's Brigade. Upton shifted Colonel Joseph Hamblin's Brigade up a ridge, and Grimes fell back to the "L"-shaped Smithfield Redoubt on high ground near the Smithfield House. Lee's force and Chapman's artillery held back Union cavalry on both sides of the pike. At the same time Upton attacked Breckinridge's right flank, Torbert's cavalry attacked his left at Fort Collier near the Martinsburg Pike. Torbert used a battery from the 3rd U.S. Artillery, commanded by Lieutenant William C. Cuyler, to kill 34 horses and mortally wound Captain Chapman. Averell's Division turned the Confederate left flank against remnants of Bean's, Ferguson's, and Smith's cavalry brigades. Merritt sent Lowell's Reserve Brigade toward Fort Collier, and drove away Payne's Cavalry Brigade. Powell's Brigade flanked the fort from the west side of the pike, and Lowell captured the fort including two of Chapman's guns. Lee was seriously wounded in the leg during the engagement but escaped. The success of Upton's infantry and Torbert's cavalry inspired Crook's men to resume the attack, and the majority of Confederate troops were now running south through Winchester. Confederate artillery saved Early's army from destruction. At the Smithfield Redoubt, Nelson's battalion covered the approach of the Union infantry along Berryville Pike and Braxton's and McLaughlin battalions fired northward at Union cavalry. They also received some assistance from horse artillery on the Winchester Heights. Early's army makes final stand VI
