When General Sherman encountered the enemy, he discovered their weakness by sending a reconnoitering party to his right, which had the effect of causing them to retreat from that part of their line. A few artillerists, however, remained in their places, firing upon General Sherman’s troops until the last moment. At this time General McClernand occupied Clinton with one division, Mississippi Springs with another, Raymond with a third, and his fourth division and General Blair’s division of General Sherman’s corps were with a wagon train, still in the rear, near Auburn. At the same time General McArthur, with one brigade of his division of General McPherson’s corps, was moving toward Raymond on the Utica road. It was not the intention of General Grant to move these forces any nearer Jackson, but to have them in a position where they could be in supporting distance if the resistance at Jackson should prove more obstinate than there seemed any reason to expect. On the retreat of the enemy, General McPherson followed directly into the city of Jackson. A fine battery of six pieces was found, and around the Deaf and Dumb Institute, which was used as a hospital, tents enough were seized to encamp an entire division. The commissary and quartermaster’s stores were in flames. The Governor and State Treasurer had withdrawn, taking the State funds and papers. All citizens officially connected with the State or Confederate Governments had also left. Many soldiers remained, besides a large number in the hospital. Early on the morning of the day following the occupation of the city of Jackson it was decided to evacuate the position. There were several reasons which induced General Grant to arrive at this decision, prominent among which was the difficulty of keeping intact his long line of communication, and the fear that General Johnston—who was known to be hovering in the region north of Jackson with a force estimated at twenty thousand men—would attack his rear. The force which he encountered just before reaching Jackson, under General Gregg, had divided, one portion going to Canton from the north, and the other from the south. Johnston and Gregg combined might prove altogether too formidable. It was therefore decided to return to Clinton and move upon Vicksburg. The main column of the enemy was at Edwards’ Station, proposing to give battle there. Soon after daylight the column was in motion, General McPherson in advance. They reached Clinton at noon, and after an hour’s delay marched to their camping ground, a short distance from the village of Bolton.
