McClernand and Sherman formed part of the line of battle. Prentiss' division was gone. The other two divisions, what was left of them, acted in reserve. Hurlbut formed his division in the morning complete, with the exception of the Forty-sixth Illinois, which served for the day with McClernand. It was a skeleton division. The Third Iowa was 140 men under the command of a lieutenant. In the forenoon, General Grant sent Hurlbut out to act as reserve to McClernand. The Twenty-eighth Illinois took place for a while on McClernand's left, and Veatch with his three regiments took place on McCook's left, when he diverged from Crittenden. Colonel Tuttle, senior officer in the Second Division, by the death of W.H.L. Wallace and the wounding of McArthur, gathered the remaining regiments of his division, except the Fourteenth Missouri and the Eighty-first Ohio, added to them Colonel Crocker and three regiments of McClernand's First Brigade, and marched in reserve to Crittenden. He sent the Second Iowa to Nelson, when Nelson's line was broken by the gallant but disastrous charge of Hazen; the Eighth and Eighteenth Illinois moved out to the left of Crittenden when he diverged from Nelson, and the Seventh Iowa, moved into the front line later in the day. The number of Johnston's army has already been given as 40,000 men. Badeau says the effective force present in the National camps Sunday morning was 33,000 men. General Sherman makes the number 32,000. William Preston Johnston, in the Life of his father, makes the number of the National troops, the "grand total in Sunday's battle," 41,543. These various statements arise from the different ways of making and reading returns. Forty thousand does not represent the total force which A.S. Johnston led to Shiloh. Forty thousand "present for duty" is exclusive not only of the brigade of detailed teamsters and cooks that General Johnston complained of, but of all regular and permanent details. It appears from some reports which give numbers, that it was also exclusive of temporary details made for the occasion of the battle--hospital men, train guards, ammunition guards, sappers and miners, infantry detailed to act with batteries, etc. It appears from some of the reports, which state numbers, that the "enlisted men" "present for duty," in the "Field Returns of the Confederate Forces that marched from Corinth to the Tennessee River," comprised only non-commissioned officers and privates, and was therefore exclusive of musicians, buglers, artificers, etc., though enlisted as such. The 40,000, therefore, is the number of the combatants engaged in the battle. The field return is susceptible of further explanations, the character of which does not appear. The field return, for example, gives the "present for duty," in the artillery in Polk's corps, as 20 officers and 331 enlisted men--351 in all; while the official report of the chief of artillery of the corps, of casualties in
