the detachments of the Nineteenth with the least possible delay. General Banks was instructed to select and assign to duty with the Nineteenth Corps 2,000 of his most effective cavalry. If this has not been done you are authorized to retain that force with you until General Banks' designation of the regiments to be assigned has been received. Vicksburg, Miss., will be the depot of supplies for the troops to be assembled at Morganza, but supplies that are immediately needed will be draw from New Orleans.

If the force of infantry and cavalry from your command ordered in previous communications of this morning have not been as yet detached, it will not be necessary now to send it. If, however, it has already moved in compliance with those instructions and cannot be recalled by you, it will rejoin you as you march down.

Very respectfully, your obedient servant,

C. T. CHRISTENSEN,

Major, Assistant Adjutant-General.
