Early on May 5, Warren's V Corps was advancing south toward the Plank Road when Ewell's Corps appeared in the west on the Turnpike. Meade halted his army and directed Warren to attack if the Confederates were a small, isolated group. Ewell's men erected earthworks on the western end of the clearing known as Saunders Field. Warren requested a delay from Meade so that Sedgwick's VI Corps could be brought in on his right and extend his line. By 1 p.m., Meade was frustrated by the delay and ordered Warren to attack before Sedgwick could arrive. The brigade of Brig. Gen. Romeyn B. Ayres had to take cover in a gully to avoid enfilading fire. The brigade of Brig. Gen. Joseph J. Bartlett made better progress to Ayres's left and overran the position of Brig. Gen. John M. Jones, who was killed. However, since Ayres's men were unable to advance, Bartlett's right flank was now exposed to attack, and his brigade was forced to flee back across the clearing.
