Bolstered by 18,000 fresh troops from the divisions of Major Generals Buell and Lew Wallace, Grant counterattacked at dawn the next day and regained the field, forcing the disorganized and demoralized rebels to retreat back to Corinth. Halleck ordered Grant not to advance more than one day's march from Pittsburg Landing, stopping the pursuit of the Confederate Army. Although Grant had won the battle the situation was little changed, with the Union in possession of Pittsburg Landing and the Confederates once again holed up in Corinth. Grant, now realizing that the South was determined to fight and that the war would not be won with one battle, would later write, "Then, indeed, I gave up all idea of saving the Union except by complete conquest."
