As Torbert surveyed the scene, he realized that three regiments would be insufficient to resist the Confederate brigade, so he ordered the rest of his division to move up. Brig. Gen. Wesley Merritt's reserve brigade was the first to arrive, and his 2nd U.S. Cavalry Regiment replaced the 17th Pennsylvania, which had run low on ammunition, in the center of the line. On the right end of the Union line, the 6th New York and the 2nd U.S. pushed back the 4th South Carolina, which was soon reinforced by the Charleston Light Dragoons. The Confederates built breastworks out of logs from Liggan's farm. On the left end, the 9th New York met heavy resistance from the 5th South Carolina, which was protected by the 40-foot banks of the Matadequin. Merritt attempted to outflank the Confederate position with the 6th Pennsylvania Cavalry, commanded by Capt. Charles L. Leiper. Although they managed to cross the creek to the left of the 9th New York, they were stopped in heavy hand-to-hand combat with the South Carolinians and Leiper was severely wounded.
