Lee was unsure of Grant's plan. Reconnaissance told him that the river crossing equipment had been removed from Germanna Ford, so Grant would not be withdrawing as his predecessors had. The Union Army could either be heading east to Fredericksburg or moving south. In either event, the crossroads at Spotsylvania Court House would play an important role, so Lee ordered his artillery chief, Brig. Gen. William N. Pendleton, to begin constructing a road through the woods from the Confederate position at the Wilderness due south to the Catharpin Road. He also ordered Maj. Gen. Richard H. Anderson, who had replaced Lt. Gen. James Longstreet in command of the First Corps following that officer's wounding on May 6, to move out along that road. Lee did not indicate any need for haste, but Anderson and his men desired to leave the stench of burning forest and dead bodies in the Wilderness, so they began marching about 10 p.m.
