On August 24, Union II Corps moved south along the Weldon Railroad, tearing up track, preceded by Gregg's cavalry division. On August 25, Maj. Gen. Henry Heth attacked and overran the faulty Union position at Ream's Station, capturing 9 guns, 12 colors, and many prisoners. The old II Corps was shattered. Maj. Gen. Winfield Scott Hancock withdrew to the main Union line near the Jerusalem Plank Road, bemoaning the declining combat effectiveness of his troops.
