Mott; Getty and Gibbon were in support. Lee had assured Hill that Longstreet's Corps would arrive to reinforce Hill before dawn, but moving cross-country in the dark, they made slow progress and lost their way at times. Ewell's men on the Turnpike had attacked first, at 4:45 a.m., but continued to be pinned down by attacks from Sedgwick's and Warren's corps and could not be relied upon for assistance. Before a total collapse, however, reinforcements arrived at 6 a.m., Brig. Gen. John Gregg's 800-man Texas Brigade, the vanguard of Longstreet's column. General Lee, caught up in the excitement, began to move forward with the advancing brigade. As the Texans realized this, they halted, refusing to move forward unless Lee remained in the rear. Longstreet counterattacked with the divisions of Maj. Gen. Charles W. Field and Brig. Gen. Joseph B. Kershaw. The Union troops fell a few hundred yards back from the Widow Tapp farm. At 10 a.m., Longstreet's chief engineer reported that he had explored an unfinished railroad bed south of the Plank Road and that it offered easy access to the Union left flank. Longstreet's aide, Lt. Col. Moxley Sorrel, and the senior brigade commander, Brig. Gen. William Mahone, struck at 11 a.m. with four brigades. At the same time, Longstreet resumed his main attack, driving Hancock's men back to the Brock Road, but the momentum was lost when Longstreet was wounded by his own men, putting him out of action until October. At the Turnpike, inconclusive fighting continued for most of the day. Early in the morning, Brig. Gen. John B. Gordon scouted the Union line and recommended to his division commander, Jubal Early, that he conduct a flanking attack, but Early dismissed the venture as too risky and did not approve it until that evening. Gordon's attack made good progress against inexperienced New York troops, but eventually the darkness and the dense foliage took their toll as the Union flank received reinforcements and recovered. On the morning of May 7, Grant chose maneuver instead of further attacks. By moving south on the Brock Road, he hoped to reach the crossroads at Spotsylvania Court House, which would interpose his army between Lee and Richmond, forcing Lee to fight on ground more advantageous to the Union army. He ordered preparations for a night march on May 7 that would reach Spotsylvania, to the southeast, by the morning of May
