In the center, Wright's corps was pinned down by the heavy fire and made little effort to advance further, still recovering from their costly charge on June 1. On the Union right, Smith's men advanced through unfavorable terrain and were channeled into two ravines. When they emerged in front of the Confederate line, rifle and artillery fire mowed them down. The artillery fire against Smith's corps was heavier than might have been expected because Warren's V Corps to his right was reluctant to advance and the Confederate gunners in Warren's sector concentrated on Smith's men instead. The only activity on the northern end of the field was by Burnside's IX Corps, facing Jubal Early. He launched a powerful assault at 6 a.m. that overran the Confederate skirmishers but mistakenly thought he had pierced the first line of earthworks and halted his corps to regroup before moving on, which he planned for that afternoon.
