The Union breakthrough was shortlived. Outnumbered and unsupported, General Isaac Stevens Federals were driven back by Stonewall Jackson's forces. A lull in the fighting came across the field, as the rainstorm turned into a severe thunderstorm. Jackson took the time to reinforce and redeploy his men. This was a prudent decision on Jackson’s part, as more Federals were marching toward his position. General Philip Kearny’s III Corps division started in support of Stevens before the latter’s death. Kearny’s men engaged with Jackson’s right flank in a cornfield held by A. P. Hill's "Light Division."
