GENERAL ORDERS, HEADQUARTERS ARMY OF THE POTOMAC,

Numbers 48.
Camp near Falmouth, Va., April 30, 1863.

The frequent transmission of false intelligence and the betrayal of the movements of the army to the enemy, by the publication of injudicious correspondence of an anonymous character, makes it necessary to require all newspaper correspondents to publish their communications over their own signatures.

In case of failure to comply with this order, through their own or their employers' neglect, such correspondents will be excluded from, and the circulation of the journals for which they correspond suppressed within, the lines of this army.

Commanding officers and provost-marshals are directed to enforce this order, and will keep themselves informed of all the correspondents within the limits of their respective camps, and should any such disregard its requirements, will send them forthwith beyond the lines of this army.

By command of Major-General Hooker:

Assistant Adjutant-General.

The private is of the rebels to take and hold this Valley at all hazards. The private is of the same regiment, and says that on Friday last he was sent by Jones with a dispatch to A. P. Hill, at Harrisonburg; that when he left there Hill's division had orders to cook five days' rations, for what purpose he did not know, but the general impression was that they were coming down to drive Milroy from Winchester. The lieutenant further stated that he left
