Fremont, hearing of the surrender on September 22d, began to bestir himself to look after Price. He left St. Louis for Jefferson City on the 27th, and sent thither the regiments that had been kept at St. Louis. Price on the same day moved out of Lexington and marched deliberately to the southwest corner of the State. On September 24th, Fremont published an order constructing an army for the field of five divisions, entitled right wing, centre, left wing, advance, and reserve--under the command, respectively, of Generals Pope, McKinstry, Hunter, Sigel, and Ashboth; headquarters being respectively at Booneville, Syracuse, Versailles, Georgetown, and Tipton. The regiments and batteries assigned to the respective divisions were scattered all over the State, many of them without wagons, mules, overcoats, cartridge-boxes, or rations. Orders were issued to advance and concentrate at Springfield. Sigel arrived there on the evening of October 27th, and Ashboth on the 30th. Fremont was convinced that Price was on Wilson's Creek, ten or twelve miles from Springfield. Despatches were sent urging McKinstry, Hunter, and Pope to hasten. Pope, having marched seventy miles in two days, arrived on November 1st, and McKinstry arrived close behind him. On November 2d an order came from Washington relieving Fremont from command of the department, and appointing Hunter to the command. Hunter having not yet come up, Fremont held a council of war, exhibited his plan of battle at Wilson Creek, and ordered advance and attack to be made next morning. General Hunter arrived in the night and assumed command. He sent a reconnoissance next day to Wilson Creek, and learned that no enemy was there or had been there. It was soon ascertained that Price was at Cassville, more than sixty miles off. The army being without rations and imperfectly supplied with transportation, General Hunter, acting upon his own judgment and also in accordance with the wish of President Lincoln expressed in a letter to him, refrained from any attempt to overtake Price, and withdrew his army back to the railroads.
