Please hand the following dispatch to General Newton immediately on his arrival:

CIRCULAR.] HEADQUARTERS ARMY OF THE POTOMAC, October 13, 1863.

There is good reason to believe that the enemy is moving on our left flank, Ewell's corps by the Warrenton pike, and Hill's by Salem and Thoroughfare Gap. It is hoped we are sufficiently far ahead to enable the seizure of the Centerville Heights in advance of the enemy, but if the movement is detected out flank and rear may be attacked, to guard against which all precautions must be taken . The supply trains will run by way of Wolf Run Shoals to Fairfax Station, and will be in striking distance if we are successful.

By command of Major-General Meade:

S. WILLIAMS,

Assistant Adjutant-General.

(Copy to all commanders.)
