General Beauregard’s evacuation of Corinth and retreat southward were accomplished in the face of a largely superior force of Union troops, and he reached the point where he intended to halt for reorganization without other loss than that sustained in the destruction of the cars and supplies at Booneville, and the capture of some stragglers and deserters that fell into our hands while we were pressing his rear from General Pope’s flank. The number of these was quite large, and indicated that the enemy was considerably demoralized. Under such circumstances, an energetic and skillfully directed pursuit might not have made certain the enemy’s destruction, but it would largely have aided in disintegrating his forces, and I never could quite understand why it was not ordered. The desultory affairs between rear and advance guards seemed as a general, thing to have no particular purpose in view beyond finding out where the enemy was, and when he was found, since no supporting colums were at hand and no one in supreme control was present to give directions, our skirmishing was of little avail and brought but small reward.
A short time subsequent to these occurrences, Colonel Elliott was made a brigadier-general, and as General Pope appointed him his Chief-of-Staff, I, on the 11th of June, 1862, fell in command of the brigade by seniority. For the rest of the month but little of moment occurred, and we settled down into camp at Booneville on the 26th of June, in a position which my brigade had been ordered to take up some twenty miles, in advance of the main army for the purpose of covering its front. Although but a few days had elapsed from the date of my appointment as colonel of the Second Michigan to that of my succeeding to the command of the brigade, I believe I can say with propriety that I had firmly established myself in the confidence of the officers and men of the regiment, and won their regard by thoughtful care. I had striven unceasingly to have them well fed and well clothed, had personally looked after the selection of their camps, and had maintained such a discipline as to allay former irritation.
