General Pope having landed at Commerce with 140 men, regiments and batteries rapidly arrived from Cairo, St. Louis, and Cincinnati. With the assistance of able and experienced officers, Generals Schuyler Hamilton, Stanley, Palmer, and Granger, the troops were brigaded, divisions formed, and the command organized. Colonel Plummer being promoted to brigadier-general after the arrival before New Madrid, the organization was modified. As finally organized, it comprised five small infantry divisions. First, commanded by General D.S. Stanley, comprising First Brigade, Colonel John Groesbeck, Twenty-seventh and Thirty-ninth Ohio; and Second Brigade, Colonel J.L.K. Smith, Forty-third and Sixty-third Ohio. Second Division, General Schuyler Hamilton, comprising First Brigade, Colonel W.H. Worthington, Fifth Iowa and Fifty-ninth Indiana; and Second Brigade, Colonel N. Perczell, Twenty-sixth Missouri Infantry and Sands' Eleventh Ohio Battery. Third Division, General J.N. Palmer, comprising First Brigade, Colonel J.R. Slack, Thirty-fourth and Forty-seventh Indiana; and Second Brigade, Colonel G.N. Fitch, Forty-third and Forty-sixth Indiana Infantry, Seventh Illinois Cavalry, and Company G, First Missouri Light Artillery. Fourth Division, comprising First Brigade, Colonel J.D. Morgan, Tenth and Sixteenth Illinois; and Second Brigade, Colonel G.W. Cumming, Twenty-sixth and Fifty-first Illinois, First Illinois Cavalry, and a battalion of Yate's sharpshooters. Fifth Division, General J.B. Plummer, comprising First Brigade, Colonel John Bryner, Forty-seventh Illinois and Eighth Wisconsin; and Second Brigade, Colonel J.M. Loomis, Twenty-second Illinois, Eleventh Missouri Infantry, and Company M, First Missouri Light Artillery. Besides these was a cavalry division, commanded by General Gordon Granger, comprising the Second and Third Michigan Cavalry; also an artillery division, commanded by Major W.L. Lothrop, comprising the following batteries: Second Iowa, Third Michigan, Company F, Second United States Artillery, Houghtaling's Ottawa Light Artillery, Fifth, Sixth, and Seventh Batteries of the First Wisconsin Artillery, and De Golyer's battery, afterward Company H, of the First Michigan Artillery. In addition to these was a command under Colonel J.W. Bissel, called the Engineer's Regiment of the West, comprising the Fifteenth Wisconsin and Twenty-second Missouri Infantry, the Second Iowa Cavalry, a company of the Fourth United States Cavalry, a company of the First United States Infantry, and battalion of the Second Illinois Cavalry. The army commander, the division commanders, and other officers, nearly a dozen in all, were graduates of West Point. The men of this army had, therefore, better opportunity than most others to learn quickly something of the business of military life, and acquire habits of military discipline.
