Sheridan, who would be characterized in later battles as very aggressive, hesitated to pursue the smaller force, and also refused a request by Daniel McCook to move north in support of his brother's corps. However, his earlier request for reinforcements bore fruit and the 31st Brigade of Col. William P. Carlin (Mitchell's division) moved up on Sheridan's right. Carlin's men moved aggressively in pursuit of Powel, chasing them as fast as they could run toward Perryville. As they reached the cemetery on the western outskirts of town, fierce artillery dueling commenced. Carlin pressed forward and was joined by the 21st Brigade of Col. George D. Wagner (Wood's division, II Corps). They were poised to capture the town and the critical crossroads that dominated Braxton Bragg's avenue of withdrawal, but an order from Gilbert to Mitchell curtailed the advance, despite Mitchell's furious protestations.
