The heads of all the columns had entered the rebel lines about the same time, and there was some rather foolish clamor for the first honors, but in fact there was no honor in the event.  Beauregard had made a clean retreat to the south, and was only seriously pursued by cavalry from General Pope’s flank.  But he reached Tupelo, where he halted for reorganization; and there is no doubt that at the moment there was much disorganization in his ranks, for the woods were full of deserters whom we did not even take prisoners, but advised them to make their way home and stay there.  We spent the day at and near the college, when General Thomas, who applied for orders at Halleck’s headquarters, directed me to conduct my division back to the camp of the night before, where we had left our trains The advance on Corinth had occupied all of the month of May, the most beautiful and valuable month of the year for campaigning in this latitude.  There had been little fighting, save on General Pope’s left flank about Farmington; and on our right.  I esteemed it a magnificent drill, as it served for the instruction of our men in guard and picket duty, and in habituating them to out-door life; and by the time we had reached Corinth I believe that army was the best then on this continent, and could have gone where it pleased.  The four subdivisions were well commanded, as were the divisions and brigades of the whole army.  General Halleck was a man of great capacity, of large acquirements, and at the time possessed the confidence of the country, and of most of the army.  I held him in high estimation, and gave him credit for the combinations which had resulted in placing this magnificent army of a hundred thousand men, well equipped and provided, with a good base, at Corinth, from which he could move in any direction.

Had he held his force as a unit, he could have gone to Mobile, or Vicksburg, or anywhere in that region, which would by one move have solved the whole Mississippi problem; and, from what he then told me, I believe he intended such a campaign, but was overruled from Washington.  Be that as it may, the army had no sooner settled down at Corinth before it was scattered:  General Pope was called to the East, and his army distributed among the others; General Thomas was relieved from the command of the right wing, and reassigned to his division in the Army of the Ohio; and that whole army under General Buell was turned east along the Memphis & Charleston road, to march for Chattanooga.  McClernand’s “reserve” was turned west to Bolivar and Memphis.  General Halleck took post himself at Corinth, assigned Lieutenant-Colonel McPherson to take charge of the railroads, with instructions to repair them as far as Columbus, Kentucky, and to collect cars and locomotives to operate them to Corinth and Grand Junction.  I was soon dispatched with my own and Hurlbut’s divisions northwest fourteen miles to Chewalla, to save what could be of any value out of six trains of cars belonging to the rebels which had been wrecked and partially burned at the time of the evacuation of Corinth.
