At Lexington on June 11, Hunter fought with Confederate cavalry under Brig. Gen. John McCausland, who withdrew to Buchanan. Hunter ordered Col. Alfred N. Duffié to join him in Lexington with his cavalry division. While waiting, Hunter burned Virginia Military Institute and the home of John Letcher, former Governor of Virginia. After being joined by Duffié on June 13, Hunter sent Averell to drive McCausland out of Buchanan and capture the bridge there across the James River, but McCausland burned the bridge and fled the town. Hunter joined Averell in Buchanan the following day before advancing via the road between the Peaks of Otter on June 15. His cavalry occupied Liberty that evening.
