Lieutenant-Colonel HOFFMAN, U. A. Army.

DEAR SIR: Will you please inform us if in your ability the probable date when we may be relieved from guarding the prisoners? Much has been said about their exchange, and you have I learn ordered rolls to be prepared immediately, yet I have had no intimation of the time when they would probably be discharged. My aiming writing is to ascertain that fact so that we may have the proper force here to guard them, two-thirds of the present guard being State militia called here July 17 for thirty days, who will want to return to their homes at the expiration of that time.

Yours, respectfully,

LAZ. NOBLE,

Adjutant-General.
