Edwin V. Sumner to Edward D. Townsend, August 23, 1861

Lieut. Col. E. D. TOWNSEND,

SIR: I have the honor to inform the General-in-Chief that, in consequence of threatened disturbances among several Indian tribes in the District of Oregon, I have Directed Colonel Wright, the commander thereof, whenever in his opinion it is necessary, to muster into service a sufficient volanteer force for the suppression of any outbreak. This force I have directed shall be placed under the command of an officer of the Regular Army, to be selected by Colonel Wright. It would be hazardous af this time to reduce the regular force in this State, and I am therefore compelled to rely upon State troops to give the necessary protection to our frontier settlements.

Very respectfully, your obedient servant,
