There are 200 cavalry at Culpeper, and about three companies at the Rapidan Station. A scout of the Sixth Virginia Cavalry was captured. He reports the concentration of Ewell's corps immediately to the west of Manassas Gap; that supplies are sent them from Culpeper Court-House. Scouts have been sent out toward Blue Ridge in the direction of the gaps.
