On the rainy morning of April 6, Humphreys's corp initially moved toward the Confederate wagon train near Amelia Springs on the road to Amelia Court House. At Amelia Springs, Brigadier General (Brevet Major General) Gershom Mott was wounded while reconnoitering with the skirmish line and was replaced as division commander by Brigadier General Philippe Régis de Trobriand. Units of the II Corps moving toward Amelia Court House in accordance with Meade's order, which was in the opposite direction of the Confederate march, observed Lee's army moving west just before the rear guard passed out of sight. At about the same time, Union signal officers discovered wagon trains and infantry moving toward Deatonville while Brigadier General (Brevet Major General) Charles Griffin's V Corps, at Hill's Shop, also learned that Lee's force had left Amelia Court House. As the westward movement of the Confederate Army became apparent, the II Corps changed direction and gave pursuit. Griffin's V Corps was sent on a wide swing to the north of the Confederate column through Paineville and was beyond the action on April 6.
