Before daylight on October 4 the Confederate artillery opened a vigorous fire on the enemy’s works, and a lively contest between the gray and blue cannon was kept up until after daylight. During the early morning there was sharp fighting on the skirmish line in front of the Second Texas, in which the Union skirmishers were driven in and their commander, Col. Joseph A. Mower, was severely wounded and captured, but again fell into the hands of his friends that evening after our retreat from Corinth. Directly in front of the Second Texas, a short distance north of the Memphis and Charleston Railroad, was “Fort Robinette,” with three twenty-pound siege guns; and in “Fort Williams,” on the south side of the railroad, there were four twenty-four pounders and two eight-inch Howitzers. On the eminence between “Fort Williams” and the railroad were six guns of Battery F., U. S. Light Artillery; and on the south side of the same fort were two guns of the Second Illinois Light Artillery--all commanding the field to the westward and in positions to sweep the hillside in front of “Robinette.” In addition to these, two guns of the Wisconsin Light Artillery occupied a point just north of and very close to “Robinette,” between it and the Chewalla dirt road, and in a position to sweep the top and side of the hill in front. These were the positions of the Union artillery, seventeen guns in all, in front of the Second Texas Regiment and commanding the ground over which that wonderful organization of fighters was about to deliver one of the most daring and desperate assaults in the history of wars. The Union infantry was also placed advantageously for dealing destruction to the assaulting column. The Forty-Seventh Illinois Regiment lay behind the railroad, immediately in front of “Fort Williams,” covering the hillside with their deadly Springfield rifles. The Forty-Third Ohio occupied the ground immediately behind the breastworks on the north side of “Robinette,” with its left near the fort. The Eleventh Missouri was lying down under the hill, about fifty yards in the rear of “Robinette,” with its right and left wings expanding opposite the Forty-Third and Sixty-Third Ohio, respectively. The Twenty-Seventh Ohio occupied the trenches on the right of the Sixty-Third; and the Thirty-Ninth Ohio was still further to the north, on the right of the Twenty-Seventh, with its right wing facing north, at right angles to the line of its left wing and to the Twenty-Seventh and the Sixty-Third.
