The scout under Colonel Clendenin, Eighth Illioins Cavalry, to Loudoun Valley has just returned. Captured 2 rebels and 20 horses. Mosey, with one battalion, on Saturday crossed Blue Ridge to the Shenandoah to capture and plunder Hancock's trains south of CK] when a safe opportunity offers. One company of Mosey's men was sent to steal horses from my lines. The battalion from mosey Northern Neck came to-day to steal mosey quartermaster's animals at Mosey's Station, and was badly whipped by the Eighth Illinois Cavalry at Fairfax and Mosey's Station. Five rebels killed, 6 horses and equipments captured, and 8 horses killed. Our loss was 2 men slightly wounded, 5 horses killed, and 4 horses wounded. The rebels outnumbered us three to one, but the Eighth Illinois Cavalry will fight anything. General Augur's telegram received, and will be answered to-morrow morning.
