From his position on the right flank, Custer's division crossed Little Sailor's Creek at Gill Mill and noticed the gap between Mahone and Anderson about away at Marshall's Crossroad and blocked the road there while Crook's troopers were attacking the rear of Anderson's column. In this space were slowly-moving artillery pieces. Custer's men charged the artillery, capturing ten pieces before being driven off by Anderson's infantry. Other Union cavalry came up to harass Anderson's line. Anderson's men counterattacked but then held up. A Virginia soldier late said that a large number of Union troopers then moved ahead of them while they were digging in instead of moving on.
