[Illustration: CAPT. PETER BUTLER.] ------------------------------------------------------------------------ The officers of the Spy Battalion, so far as known, were: Major, William L.D. Ewing; Paymaster, Frederick Remann; Quartermaster, David H. Moore; Surgeon, John Allan Wakefield; Quartermaster’s Sergeant, Alanson Powell. It was composed of the companies of Captains Allan F. Lindsay of Morgan County and Samuel Huston of Fayette County. On the 21 st Brady was ordered to take command of the forces at Dixon’s when he arrived there, but before starting out he was to detail ten men from each brigade for duty with the convoys of wagons, which said detail was to report daily to Col. E.C. March, Quartermaster-General. At 2 o’clock of the same day Alexander’s Brigade started for Dixon’s Ferry, after receiving General Order No. 41: “Headquarters, Army of the Frontier, “Rapids of the Illinois, 20 June, 1832. “The movement of the mounted volunteers on the march, whether in division or brigade, will be in columns by heads of regiments or battalions. An advance flank and rear guard will be constantly thrown out on the march; its distance from the main body will be regulated according to the nature of the ground, by the officer of the day, under the direction of the commander or senior officer present. Should the troops be attacked in front, flank and rear on the march, the line would be formed in either direction by regiments on foot previously named (as will also the reserve in either case). The form of the encampment will be a square. The troops having occupied the ground designated for the encampment will remain on horseback until the guard is posted, when the order to dismount will be given by a signal, and tents pitched; the train of wagons will then go formed in line within a square, in rear of the line of tents. The horses will be grazed until night, when, at a given signal, to be given for that purpose, they will be picketed in lines in the area within the line of wagons. “The fires will be at least forty yards in front of the line of tents. Should the camp be attacked, the line will be formed on foot immediately in front of the line of tents. “It is of the utmost importance that the ammunition should not be wasted. The commanders of brigades will see that the greatest care is taken of that issued to their respective commands. “A.S. JOHNSTON, A.D.C., A.A.A. General.” “Headquarters, Army of the Frontier, “Foot of the Rapids of the Illinois, June 21, 1832. “Order No. 43.
