HEADQUARTERS DEPARTMENT OF THE NORTHWEST, Saint Paul, Minn., September 28, 1862. Col. H. H. SIBLEY, Commanding Sioux Expedition: COLONEL:...........No treaty must be made with the Sioux, even should the campaign against them be delayed until the summer. If they desire a council, let them come in, but seize Little Crow and all others engaged in the late outrages, and hold them prisoners until further orders from these headquarters. It is idle and wicked, in view of the atrocious murders these Indians have committed, in the face of treaties and without provocation, to make treaties or talk about keeping faith with them. The horrible massacres of women and children and the outrageous abuse of female prisoners, still alive, call for punishment beyond human power to inflict. There will be no peace in this region by virtue of treaties and Indian faith. It is my purpose utterly to exterminate the Sioux if I have the power to do so and even if it requires a campaign lasting the whole of next year. Destroy everything belonging to them and force them out to the plains, unless, as I suggest, you can capture them. They are to be treated as maniacs or wild beasts, and by no means as people with whom treaties or compromises can be made. Urge the campaign vigorously; you shall be as vigorously supported and supplied. I send this letter by Colonel Miller, who goes to take command of his regiment, the Seventh. Please keep me advised frequently of your movements.

Very respectfully, your obedient servant, JNO. POPE, Major- General, Commanding. (United States Army)
