Bear Creek, a few miles to the east of the Fulton road, is a formidable obstacle to the movement of troops in the absence of bridges, all of which, in September, 1862, had been destroyed in that vicinity. The Tennessee, to the north-east, not many miles away, was also a formidable obstacle for an army followed by a pursuing force. Ord was on the north-west, and even if a rebel movement had been possible in that direction it could have brought only temporary relief, for it would have carried Price's army to the rear of the National forces and isolated it from all support. It looked to me that, if Price would remain in Iuka until we could get there, his annihilation was inevitable.

On the morning of the 18th of September General Ord moved by rail to Burnsville, and there left the cars and moved out to perform his part of the programme. He was to get as near the enemy as possible during the day and intrench himself so as to hold his position until the next morning. Rosecrans was to be up by the morning of the 19th on the two roads before described, and the attack was to be from all three quarters simultaneously. Troops enough were left at Jacinto and Rienzi to detain any cavalry that Van Dorn might send out to make a sudden dash into Corinth until I could be notified. There was a telegraph wire along the railroad, so there would be no delay in communication. I detained cars and locomotives enough at Burnsville to transport the whole of Ord's command at once, and if Van Dorn had moved against Corinth instead of Iuka I could have thrown in reinforcements to the number of 7,000 or 8,000 before he could have arrived. I remained at Burnsville with a detachment of about 900 men from Ord's command and communicated with my two wings by courier. Ord met the advance of the enemy soon after leaving Burnsville. Quite a sharp engagement ensued, but he drove the rebels back with considerable loss, including one general officer killed. He maintained his position and was ready to attack by daylight the next morning. I was very much disappointed at receiving a dispatch from Rosecrans after midnight from Jacinto, twenty-two miles from Iuka, saying that some of his command had been delayed, and that the rear of his column was not yet up as far as Jacinto. He said, however, that he would still be at Iuka by two o'clock the next day. I did not believe this possible because of the distance and the condition of the roads, which was bad; besides, troops after a forced march of twenty miles are not in a good condition for fighting the moment they get through. It might do in marching to relieve a beleaguered garrison, but not to make an assault. I immediately sent Ord a copy of Rosecrans' dispatch and ordered him to be in readiness to attack the moment he heard the sound of guns to the south or south-east. He was instructed to notify his officers to be on the alert for any indications of battle. During the 19th the wind blew in the wrong direction to transmit sound either towards the point where Ord was, or to Burnsville where I had remained.

A couple of hours before dark on the 19th Rosecrans arrived with the head of his column at Barnets, the point where the Jacinto road to Iuka leaves the road going east. He here turned north without sending any troops to the Fulton road. While still moving in column up the Jacinto road he met a force of the enemy and had his advance badly beaten and driven back upon the main road. In this short engagement his loss was considerable for the number engaged, and one battery was taken from him. The wind was still blowing hard and in the wrong direction to transmit sounds towards either Ord or me. Neither he nor I nor any one in either command heard a gun that was fired upon the battle-field. After the engagement Rosecrans sent me a dispatch announcing the result. This was brought by a courier. There was no road between Burnsville and the position then occupied by Rosecrans and the country was impassable for a man on horseback. The courier bearing the message was compelled to move west nearly to Jacinto before he found a road leading to Burnsville. This made it a late hour of the night before I learned of the battle that had taken place during the afternoon. I at once notified Ord of the fact and ordered him to attack early in the morning. The next morning Rosecrans himself renewed the attack and went into Iuka with but little resistance. Ord also went in according to orders, without hearing a gun from the south of town but supposing the troops coming from the south-west must be up by that time. Rosecrans, however, had put no troops upon the Fulton road, and the enemy had taken advantage of this neglect and retreated by that road during the night. Word was soon brought to me that our troops were in Iuka. I immediately rode into town and found that the enemy was not being pursued even by the cavalry. I ordered pursuit by the whole of Rosecrans' command and went on with him a few miles in person. He followed only a few miles after I left him and then went into camp, and the pursuit was continued no further. I was disappointed at the result of the battle of Iuka—but I had so high an opinion of General Rosecrans that I found no fault at the time.

CHAPTER XXIX.

VAN DORN'S MOVEMENTS—BATTLE OF CORINTH—COMMAND OF THE DEPARTMENT OF THE TENNESSEE.

On the 19th of September General Geo. H. Thomas was ordered east to reinforce Buell. This threw the army at my command still more on the defensive. The Memphis and Charleston railroad was abandoned, except at Corinth, and small forces were left at Chewalla and Grand Junction. Soon afterwards the latter of these two places was given up and Bolivar became our most advanced position on the Mississippi Central railroad. Our cavalry was kept well to the front and frequent expeditions were sent out to watch the movements of the enemy. We were in a country where nearly all the people, except the negroes, were hostile to us and friendly to the cause we were trying to suppress. It was easy, therefore, for the enemy to get early information of our every move. We, on the contrary, had to go after our information in force, and then often returned without it.

On the 22d Bolivar was threatened by a large force from south of Grand Junction, supposed to be twenty regiments of infantry with cavalry and artillery. I reinforced Bolivar, and went to Jackson in person to superintend the movement of troops to whatever point the attack might be made upon. The troops from Corinth were brought up in time to repel the threatened movement without a battle. Our cavalry followed the enemy south of Davis' mills in Mississippi.

On the 30th I found that Van Dorn was apparently endeavoring to strike the Mississippi River above Memphis. At the same time other points within my command were so threatened that it was impossible to concentrate a force to drive him away. There was at this juncture a large Union force at Helena, Arkansas, which, had it been within my command, I could have ordered across the river to attack and break up the Mississippi Central railroad far to the south. This would not only have called Van Dorn back, but would have compelled the retention of a large rebel force far to the south to prevent a repetition of such raids on the enemy's line of supplies. Geographical lines between the commands during the rebellion were not always well chosen, or they were too rigidly adhered to.

Van Dorn did not attempt to get upon the line above Memphis, as had apparently been his intention. He was simply covering a deeper design; one much more important to his cause. By the 1st of October it was fully apparent that Corinth was to be attacked with great force and determination, and that Van Dorn, Lovell, Price, Villepigue and Rust had joined their strength for this purpose. There was some skirmishing outside of Corinth with the advance of the enemy on the 3d. The rebels massed in the north-west angle of the Memphis and Charleston and the Mobile and Ohio railroads, and were thus between the troops at Corinth and all possible reinforcements. Any fresh troops for us must come by a circuitous route.

On the night of the 3d, accordingly, I ordered General McPherson, who was at Jackson, to join Rosecrans at Corinth with reinforcements picked up along the line of the railroad equal to a brigade. Hurlbut had been ordered from Bolivar to march for the same destination; and as Van Dorn was coming upon Corinth from the north-west some of his men fell in with the advance of Hurlbut's and some skirmishing ensued on the evening of the 3d. On the 4th Van Dorn made a dashing attack, hoping, no doubt, to capture Rosecrans before his reinforcements could come up. In that case the enemy himself could have occupied the defences of Corinth and held at bay all the Union troops that arrived. In fact he could have taken the offensive against the reinforcements with three or four times their number and still left a sufficient garrison in the works about Corinth to hold them. He came near success, some of his troops penetrating the National lines at least once, but the works that were built after Halleck's departure enabled Rosecrans to hold his position until the troops of both McPherson and Hurlbut approached towards the rebel front and rear. The enemy was finally driven back with great slaughter: all their charges, made with great gallantry, were repulsed. The loss on our side was heavy, but nothing to compare with Van Dorn's. McPherson came up with the train of cars bearing his command as close to the enemy as was prudent, debarked on the rebel flank and got in to the support of Rosecrans just after the repulse. His approach, as well as that of Hurlbut, was known to the enemy and had a moral effect. General Rosecrans, however, failed to follow up the victory, although I had given specific orders in advance of the battle for him to pursue the moment the enemy was repelled. He did not do so, and I repeated the order after the battle. In the first order he was notified that the force of 4,000 men which was going to his assistance would be in great peril if the enemy was not pursued.
