Morganza, La., July 4, 1864.

Colonel E. J. DAVIS,

Commanding Cavalry:

COLONEL: The commanding general directs that you proceed with your available force at an early hour to-morrow morning to the Atchafalaya, and a thorough reconnaissance to the Atchafalaya. On arriving at the Atchafalaya you will be governed by the information you may receive of the movements of the enemy. It is particularly important at this time that the whole of the country between here and the Atchafalaya should be thoroughly reconnoitered. On you arrival at the Grossetete road you will detach sufficient men to go after the cattle of which the general spoke to you this a. m. This order is given under the supposition that transportation cannot be furnished in several days for the removal of your force. If it should arrive you can be recalled in a few hours. You will take with you such rations as may be considered necessary, but it is desirable that you should return here in two days, if possible.

I am, colonel, respectfully,

FREDERIC SPEED,

Assistant Adjutant-General.
