Reynolds was ordered to conduct a spoiling attack south of the turnpike and encountered Longstreet's men, causing him to call off his demonstration. Pope dismissed Reynolds's concern as a case of mistaken identity, insisting that Reynolds had run into Porter's V Corps, preparing to attack Jackson's flank. Jesse Reno ordered a IX Corps brigade under Col. James Nagle to attack the center of Jackson's line again. This time Brig. Gen. Isaac R. Trimble's brigade was driven back from the railroad embankment, but Confederate counterattacks restored the line and pursued Nagle's troops back into the open fields until Union artillery halted their advance.Greene, p. 33; Martin, pp. 183–84; Hennessy, pp. 259–65.
