In Aug. 1864, part of Confederate Lt. Gen. Richard H. Anderson’s corps threatened the left of Union Maj. Gen. Philip H. Sheridan’s army. As Brig. Gen. Wesley Merritt’s division approached on 15 Aug. to protect the Federal flank, Anderson ordered Brig. Gen. William T. Wofford’s infantry brigade and Brig. Gen. Williams C. Wickham’s cavalry brigade across the Shenandoah River to confront Merritt. Wickham was overwhelmed, however, on 16 Aug., and his troopers retreated toward Front Royal while Union Brig. Gen. George A. Custer’s brigade drove Wofford from Guard Hill. Sheridan then retired north to Charles Town, W. Va.
