A.P. Hill's approach on the Plank Road that afternoon was detected, and Meade ordered the VI Corps division of Brig. Gen. George W. Getty to defend the important intersection with the Brock Road. Getty's men arrived just before Hill's and the two forces skirmished briefly, ending with Hill's men withdrawing a few hundred yards west of the intersection. Meade sent orders to Hancock directing him to move his II Corps north to come to Getty's assistance. As the Union men approached the position of Maj. Gen. Henry Heth, they were pinned down by fire from a shallow ridge to their front. As each II Corps division arrived, Hancock sent it forward to assist, bringing enough combat power to bear that Lee was forced to commit his reserves, the division commanded by Maj. Gen. Cadmus M. Wilcox. Fierce fighting continued until nightfall with neither side gaining an advantage.
