McClellan brought his army within several miles of Richmond and in late May, Johnston planned an offensive to attack the two Union corps south of the Chickahominy River. Huger's Division was to follow in support of the division of D.H. Hill, traveling down the Williamsburg Road. On May 31, when the plan was put into motion, though, James Longstreet led his division down the Williamsburg Road, delaying the entire offensive. Huger's Division spent the first night of the battle on the Charles City Road, with Mahone's Brigade guarding the army's right flank.
