Sheridan's division did participate toward the end of the battle. The Confederate brigade of Col. Samuel Powel (Anderson's division) was ordered to advance in conjunction with Adams's brigade, on Cleburne's left. The two brigades were widely separated, however, with Powel's on Edwards House Hill, immediately west of Perryville. At about 4 p.m., Powel received orders from Bragg to advance west on the Springfield Pike to silence the battery of Capt. Henry Hescock, which was firing into the left flank of Bragg's assault. Bragg assumed this was an isolated battery, not the entire III Corps. Three regiments of Powel's brigade encountered Sheridan's division, and although Sheridan was initially concerned by the Confederates' aggressive attack and sent for reinforcements, the three regiments were quickly repulsed.
