First Dispatch.

WASHINGTON, July 5, 4 P. M. — The latest official dispatch received here up to this hour from Gen. Meade is dated Headquarters, 7 a. m. 4th, which merely states that the enemy has withdrawn from his positions occupied for the attack on Friday. The information in the possession of Gen. Meade at that hour did not develop the character of the enemy's movement — whether it was a retreat or a manoeuver.

Reliable information received here to-day asserts that Gen. Lee's Headquarters were at Ashtown yesterday P. M. and further represents that the rebels were fortifying at New Lands' Cut, in the South mountains, apparently to cover a retreat.


HEADQUARTERS, ARMY POTOMAC, July 4 — noon. — To Maj. Gen. Halleck : — The position of affairs is not materily changed since my dispatch of 7 A. M. We now hold Gettysburg. The enemy has abandoned large numbers of his killed and wounded on the field. I shall probably be able to give you a return of our captures and losses before night, and a return of the enemy's killed and wounded in our hands.

(Signed,) GEO. G. MEADE,

Maj. Gen.
