Brigadier General A. S. WILLIAMS,

Commanding Twelfth Corps d`Armee:

GENERAL: The general commanding-Pleasonton-directs me to express his thanks for the information received through your dispatch of this date, and to state that he does not see in what way a brigade of infantry would be of service to him at Aquia Church, nor does he think the enemy would be likely to cross in that vicinity, on account of the condition of the creek. Some 350 men of this division are picketing in your front, with whom he begs you will communicate, and to whom instructions from headquarters Cavalry Corps have been sent by him.

This division has been ordered to move at daylight to Aquia Church, by the Telegraph road.

The general will be thankful for any further information you may receive, and will in turn keep you advised.

Very respectfully, your obedient servant,

A. J. COHEN,

Captain and Assistant Adjutant-General.
