ing for the rebel army at a point a few miles from Falls Church, and expected to leave to-night. Some of this party reported as having already left, but the impression, from all I can ascertain, is that they are still in the neighborhood although absent from their homes since Monday. I have ascertained the following names: [Charles] Binns, [French] Dulaney, [Dulaney] Richards, and [John] Prout; and I have information that a Captain [Benjamin] Mosier, formerly of our army, is to accompany them, taking with him 5 horses. If I could be furnished with a squad of cavalry, under charge of a reliable officer, I would endeavor to ascertain the facts concerning this matter to-night. I am, general, respectfully, your obedient servant,

Captain, and Signal Officer.

Everything quiet at the front. Captain Boyd, supposed to be at Shippensburg, who commands some cavalry, reports the rebels evacuated Chambersburg the night of July 1, at 12 o'clock, going in the direction of Greenwood and Fayetteville. The rear guard of the rebels passed through Shippensburg rapidly, not stopping. Lee,
