MANASSAS JUNCTION, July 22, 1863. (Received 12 m.)
Captain A. J. COHEN,
A. A. G., Cavalry Corps, Hdqrs. Army of the Potomac:
I have placed one brigade at Gainesville, to protect the Manassas Railroad. There is no water at Manassas Junction. One brigade will be at Broad Run, on the Orange and Alexandria Railroad. This will protect the bridges and Broad Run and Kettle Run, and can look after Mosby in the direction of Brentsville and the Occoquan. If it can be spared, McIntosh's brigade at Cedar Run would protect the railroad to Warrenton, covering all the bridges. Getting along well. Will get forage to-day. I have sent for clothing and ammunition. One regiment will be at Thoroughfare.

BEYOND PIEDMONT, July 22, 1863-7 p. m.
Captain L. B. NORTON,
Chief Signal Officer:

I moved by way of Piedmont, and reached Manassas Gap at 12. 30 p. m. to-day. At the west end of the Gap, I found General Merritt's brigade of cavalry, with one battery. Here the enemy, consisting of cavalry and infantry, are found. I was prevented by the thick haze from making an observation, but General Merritt, like myself, was of the opinion that the force at the gap was not stronger than one division, covering the passage of their trains. It is fully 3 miles from where our cavalry are to a point upon the east side of the Blue Ridge, from which a view is obtained of this Valley. Warrenton is also visible from that point. Markham, a small town at this end (east) of the Gap, to the other extremity, is a distance of fully 6 miles; hence it is impossible to communicate directly from the front to headquarters without an intermediate station. This region is infested by Mosby's men; they followed me some 4 miles this morning.
