After a brief clash on the Confederate right flank between Fitzhugh Lee and the advancing brigade of Brig. Gen. George A. Custer, Custer led his brigade on a road southwest to Trevilian Station. He found the station totally unguarded, occupied only by Hampton's trains—supply wagons, caissons containing ammunition and food, and hundreds of horses. The 5th Michigan Cavalry captured the lot, but left Custer cut off from Sheridan, and in their pursuit of the fleeing wagons, lost a number of their own men and much of their bounty. One of Wright's regiments, the 7th Georgia, got between Custer's force and Trevilian Station. Custer ordered the 7th Michigan to charge, driving the Georgians back. Hampton now learned of the threat in his rear area and sent in three brigades. Suddenly Custer was virtually surrounded, his command in an ever-shrinking circle, as every side was charged and hit with shells. Sheridan heard the firing from Custer's direction and realized he needed help. He charged with two brigades, pushing Hampton's men back all the way to the station, while a third brigade swung into Fitzhugh Lee's exposed right flank, thus pushing him back. Hampton fell back to the west, Lee to the east, and the battle ended for the day with the Federals in possession of Trevilian Station.
