Hardee established a line of defense across the three roads leading into Perryville from the north and west. Until reinforcements could arrive, he was limited to three of the four brigades of Buckner's division. Brig. Gen. Sterling A. M. Wood was placed at the north of town. Brig. Gen. Bushrod Johnson was to Wood's right, east of the Chaplin River near the Harrodsburg Pike. Brig. Gen. St. John R. Liddell's Arkansas Brigade formed on the crest of Bottom Hill, just east of Bull Run Creek, a tributary of Doctor's Creek, with one regiment, the 7th Arkansas, sent forward to Peters Hill on the other side of the creek. On the evening of October 7 the final Confederate forces began to arrive. The first of Patton Anderson's four brigades reached the area around 3 p.m. Brig. Gen. Patrick Cleburne's brigade, the remainder of Buckner's division, followed. Around midnight, three brigades of Frank Cheatham's division arrived, moving quickly and enthusiastically, having left their baggage train behind; his fourth brigade, under Brig. Gen. Preston Smith, received orders to return to Harrodsburg.
