The 1st Cavalry Regiment began its formation in May, 1862 and became a four-company battalion at Winchester, Virginia in November. It appears that only four addtional companies ever joined the unit. The 1st Cavalry served in W. E. Jones', F. Lee's, and Lomax's Brigade, then the Maryland Line. Later it was under the command of W.L. Jackson, W.H. Payne, and T.T. Munford. It fought in the Shenandoah Valley of Virginia, the Pennsylvania Campaign, and at Beaver Dam Station, Pollard's Farm, and Trevillian's Station. The unit continued the fight in Early's Washington Campaign, McCausland's raid on Chambersburg, and later in the Shenandoah Valley and around Appomattox. In April, 1865, it cut through Federal lines at Appomattox and disbanded.
