this department was still further enlarged by taking in the department of Pennsylvania.
Once in full command of the twelve brigades, the five unattached regiments of infantry, and the numerous bodies of cavalry and artillery in his division, on the 5th of August McClellan called upon his outposts for information concerning the Confederate forces in his front. On the 25th of August a scout was sent into Virginia from the Great Falls, some 15 miles above Washington, with which Stuart had combat; on the 27th and 28th skirmishes took place at Bailey's and Ball's cross roads with the scouting parties of that vigilant "eyes-and-ears" of Johnston's command, in the immediate vicinity of Washington; and again on the 31st at Munson's hill, on the Leesburg turnpike, and along the Little river, or Fairfax turnpike, short distances from Alexandria.

This done, at about 2 p. m., orders were given to return to camp, and the pickets were called in and the return march begun.
