Major General Grant established his headquarters at the Champion house. He ordered his 10,000 men on the Jackson Road to move forward in magnificent style with flags flying. The long blue lines extended westward beyond the Confederate flank. To meet this threat, Confederate troops shifted farther to the west creating a gap between the forces defending the crossroads and those defending the Raymond Road.

By 11:30 a.m. the Federals closed in on the Confederate main line of resistance. With a cheer they stormed the position. The fighting was intense as the battle raged on Champion Hill. The lines swayed back and forth as charge and countercharge were made. Shortly after 1:00 p.m. the strength of numbers prevailed. The blue tide swept over the crest of Champion Hill.

The Confederates fell back in disorder to the Jackson Road followed closely by the hard-driving Federals. The powerful Union drive captured the crossroads and severed the jackson Road escape route. Confronted by disaster, Pemberton ordered his two remaining divisions to counterattack. Leaving one brigade to guard the Raymond Road, the Confederates moved from their right along the Ratliff Road toward the crossroads. Brigadier General John S. Bowen's 4,500 men attacked the Federals near the crossroads. Using bayonets they drove the Federals back and gained control of Champion Hill. Outnumbered, the Confederate attack faltered short of the Champion house.

Grant ordered up fresh troops to drive back the Confederates and moved the Federals forward along the Middle and Raymond roads. Confederate resistance was shattered and Pemberton ordered his army from the field.
