As Maj. Gen. Philip Sheridan concentrated his army near Charles Town, Lt. Gen. Jubal Early and Maj. Gen. Richard Anderson attacked the Federals with converging columns on August 21. Early moved east via Smithfield against the Union VI Corps. Anderson struck north against Wilson's Union cavalry at Summit Point. There was cavalry fighting near Berryville. The Federals fought effective delaying actions, withdrawing to near Halltown on the following day.
