By mid-afternoon, as the fighting moved north on this part of the battlefield, the high ground about 400 yards ahead was held by Union Gen. Henry Bohlen's brigade. After Federals were driven from the wooded hill to the left, Bohlen's brigade and its four cannon became the Union army's front line there as Confederate Gen. Isaac Trimble moved through the ravine to the left with half of the 15th Alabama toward them. Realizing the Federals were too strong to attack alone, Trimble was reinforced by the 13th and 25th Virginia under Col. James A. Walker and ordered Walker to move on his right and advance in line of battle. The slope caused Walker's men to crowd Trimble's troops, so Walker was ordered farther right, a movement that exposed his men to musket fire in their flank. As the 13th Virginia rose to the top of the hill ahead, Sgt. Samuel Buck recalled that they came face to face with more enemy than he had ever seen, which opened on them with grape, canister, and small arms, mowing the wheat around them like a hailstorm, and that only pride and duty kept him from running. A Union artillery commander, fearing for the cannon, ordered them withdrawn, and the infantry had to follow. A northern newspaper correspondent observed that the Union troops slowly returned to the position they had occupied in the morning. The Confederates then occupied the ground the Federals had vacated, and the fighting on this part of the field ended.
