Arrived.
--Lieut. James Vaughan, of Capt. Boggs' Company, First Regiment Virginia Volunteers, arrived in Richmond on Saturday, from Manassas Junction, in charge of two prisoners of war--one a private in the regular service of the late United States, and the other one of Billy Wilson's ‘"Pet Lambs"’--a Zouave in undress uniform. Both were taken prisoners at a place called Cloud's Mills, in Fairfax county, Va., while reconnoitering. The prisoners were taken before the Secretary of War, and were ordered to the Depot to join the other Lincolnites in confinement there.
