Hampton now learned of the threat in his rear area and withdrew Rosser's Brigade from protecting his left flank and sent them to the station, converging with Lee's approach from Louisa Court House and with Wright's and Butler's brigades. Suddenly Custer found his luck had run out as he was pressured from three sides at the station. He pulled out and headed along the Gordonsville Road, taking his burdensome spoils with him. However, he failed to note a Confederate horse artillery battery on a hill north of the station, which opened fire as soon as his men were in range. At this point his right flank was further overwhelmed by Hampton's charging brigades.
