His first act was to order the discharge of the volunteer forces, which immediately marched to Dixon’s Ferry for that purpose, Dodge’s battalion excepted, and then on the 10th, at 6 o’clock, he started down the Mississippi for Fort Armstrong, on the boat Warrior, with two companies of U.S. Infantry, eight members of the Sixth Infantry and General Atkinson and staff, transferring the scene to Fort Armstrong.[261] On the 11th Port Armstrong was reached. On leaving Chicago, Scott left orders for Lieut.-Col. Abraham Eustis to follow his general route to Fort Crawford with all the well troops which had arrived, or might arrive before the 3d August,[262] which Colonel Eustis did, but upon reaching Dixon’s Ferry an express from Scott informed the Colonel of the termination of the war and ordered him to follow Rock River down its left bank, along the route used by Atkinson, to its mouth, and establish his camp at Fort Armstrong on Rock Island. On this march Colonel Eustis reached Dixon’s Ferry on the 17th,[263] resting there until the 22d of August,[264] when he moved down to Fort Armstrong and camped a short distance from the mouth of Rock River, about four miles from Atkinson’s men. On the 12th Scott sent Lieutenant Buchanan on the steamboat Warrior to bring down all prisoners[265] surrendered to that period, after which he began the examination of witnesses to ascertain the names of those who actively assisted Black Hawk and those who were his passive allies, in order to act intelligently in adjusting the treaties expected to be made September 10th, with reference to the settlement of damages sustained by the United States. On the evening of the 13th Keokuk, with fifty or sixty Sacs and Foxes, arrived in camp and reported that he had visited all the Sac and Fox villages, and that none of Black Hawk’s band had yet arrived. He further reported that he had ordered forty-two braves in the direction of the “Ioway,” to intercept and bring in any stragglers as they might appear. On the 14th Keokuk delivered to Scott a brave who had murdered a white man, just before, in the vicinity of the Yellow Banks. On the 15th Atkinson, with his staff, viz., Lieutenants Johnston, Wheelwright and Dorrance, and Captains Smith, Rogers and Hatton, Sixth Infantry, and Lieutenant Richardson, left on the steamboat Warrior for St. Louis. On or about the 26th of August the cholera again broke out with unusual virulence,[266] and again Scott actively participated in conquering it. So many Indians became affected that it became necessary to dismiss them all until they could be re-assembled by special summons. The following order became imperative: “Assistant Adjutant-General’s Office, Fort Armstrong, August 28th, 1832. Order No. 16.
