McDowell has been checked. Come down to the Shenandoah Valley with such troops as can be spared from Western Virginia, and make head against the enemy in that quarter. Banks and Dix will remain at Baltimore, which is liable to revolt.

Let the two New Jersey regiments remain at Fairfax Station, as General McDowell must know they are there, and will call them up if he needs them.
