Sherman and McPherson communicated with each other during the night and arranged to reach Jackson at about the same hour. It rained in torrents during the night of the 13th and the fore part of the day of the 14th. The roads were intolerable, and in some places on Sherman's line, where the land was low, they were covered more than a foot deep with water. But the troops never murmured. By nine o'clock Crocker, of McPherson's corps, who was now in advance, came upon the enemy's pickets and speedily drove them in upon the main body. They were outside of the intrenchments in a strong position, and proved to be the troops that had been driven out of Raymond. Johnston had been reinforced; during the night by Georgia and South Carolina regiments, so that his force amounted to eleven thousand men, and he was expecting still more.
Sherman also came upon the rebel pickets some distance out from the town, but speedily drove them in. He was now on the south and south-west of Jackson confronting the Confederates behind their breastworks, while McPherson's right was nearly two miles north, occupying a line running north and south across the Vicksburg railroad. Artillery was brought up and reconnoissances made preparatory to an assault. McPherson brought up Logan's division while he deployed Crocker's for the assault. Sherman made similar dispositions on the right. By eleven A.M. both were ready to attack. Crocker moved his division forward, preceded by a strong skirmish line. These troops at once encountered the enemy's advance and drove it back on the main body, when they returned to their proper regiment and the whole division charged, routing the enemy completely and driving him into this main line. This stand by the enemy was made more than two miles outside of his main fortifications. McPherson followed up with his command until within range of the guns of the enemy from their intrenchments, when he halted to bring his troops into line and reconnoitre to determine the next move. It was now about noon.
While this was going on Sherman was confronting a rebel battery which enfiladed the road on which he was marching—the Mississippi Springs road—and commanded a bridge spanning a stream over which he had to pass. By detaching right and left the stream was forced and the enemy flanked and speedily driven within the main line. This brought our whole line in front of the enemy's line of works, which was continuous on the north, west and south sides from the Pearl River north of the city to the same river south. I was with Sherman. He was confronted by a force sufficient to hold us back. Appearances did not justify an assault where we were. I had directed Sherman to send a force to the right, and to reconnoitre as far as to the Pearl River. This force, Tuttle's division, not returning I rode to the right with my staff, and soon found that the enemy had left that part of the line. Tuttle's movement or McPherson's pressure had no doubt led Johnston to order a retreat, leaving only the men at the guns to retard us while he was getting away. Tuttle had seen this and, passing through the lines without resistance, came up in the rear of the artillerists confronting Sherman and captured them with ten pieces of artillery. I rode immediately to the State House, where I was soon followed by Sherman. About the same time McPherson discovered that the enemy was leaving his front, and advanced Crocker, who was so close upon the enemy that they could not move their guns or destroy them. He captured seven guns and, moving on, hoisted the National flag over the rebel capital of Mississippi. Stevenson's brigade was sent to cut off the rebel retreat, but was too late or not expeditious enough.
Our loss in this engagement was: McPherson, 37 killed, 228 wounded; Sherman, 4 killed and 21 wounded and missing. The enemy lost 845 killed, wounded and captured. Seventeen guns fell into our hands, and the enemy destroyed by fire their store-houses, containing a large amount of commissary stores.
On this day Blair reached New Auburn and joined McClernand's 4th division. He had with him two hundred wagons loaded with rations, the only commissary supplies received during the entire campaign.
I slept that night in the room that Johnston was said to have occupied the night before.
About four in the afternoon I sent for the corps commanders and directed the dispositions to be made of their troops. Sherman was to remain in Jackson until he destroyed that place as a railroad centre, and manufacturing city of military supplies. He did the work most effectually. Sherman and I went together into a manufactory which had not ceased work on account of the battle nor for the entrance of Yankee troops. Our presence did not seem to attract the attention of either the manager or the operatives, most of whom were girls. We looked on for a while to see the tent cloth which they were making roll out of the looms, with "C. S. A." woven in each bolt. There was an immense amount of cotton, in bales, stacked outside. Finally I told Sherman I thought they had done work enough. The operatives were told they could leave and take with them what cloth they could carry. In a few minutes cotton and factory were in a blaze. The proprietor visited Washington while I was President to get his pay for this property, claiming that it was private. He asked me to give him a statement of the fact that his property had been destroyed by National troops, so that he might use it with Congress where he was pressing, or proposed to press, his claim. I declined.
On the night of the 13th Johnston sent the following dispatch to Pemberton at Edward's station: "I have lately arrived, and learn that Major-General Sherman is between us with four divisions at Clinton. It is important to establish communication, that you may be reinforced. If practicable, come up in his rear at once. To beat such a detachment would be of immense value. All the troops you can quickly assemble should be brought. Time is all-important." This dispatch was sent in triplicate, by different messengers. One of the messengers happened to be a loyal man who had been expelled from Memphis some months before by Hurlbut for uttering disloyal and threatening sentiments. There was a good deal of parade about his expulsion, ostensibly as a warning to those who entertained the sentiments he expressed; but Hurlbut and the expelled man understood each other. He delivered his copy of Johnston's dispatch to McPherson who forwarded it to me.
