When I reassumed command on the 17th of March I found the army divided, about half being on the east bank of the Tennessee at Savannah, while one division was at Crump's landing on the west bank about four miles higher up, and the remainder at Pittsburg landing, five miles above Crump's. The enemy was in force at Corinth, the junction of the two most important railroads in the Mississippi valley—one connecting Memphis and the Mississippi River with the East, and the other leading south to all the cotton states. Still another railroad connects Corinth with Jackson, in west Tennessee. If we obtained possession of Corinth the enemy would have no railroad for the transportation of armies or supplies until that running east from Vicksburg was reached. It was the great strategic position at the West between the Tennessee and the Mississippi rivers and between Nashville and Vicksburg.

I at once put all the troops at Savannah in motion for Pittsburg landing, knowing that the enemy was fortifying at Corinth and collecting an army there under Johnston. It was my expectation to march against that army as soon as Buell, who had been ordered to reinforce me with the Army of the Ohio, should arrive; and the west bank of the river was the place to start from. Pittsburg is only about twenty miles from Corinth, and Hamburg landing, four miles further up the river, is a mile or two nearer. I had not been in command long before I selected Hamburg as the place to put the Army of the Ohio when it arrived. The roads from Pittsburg and Hamburg to Corinth converge some eight miles out. This disposition of the troops would have given additional roads to march over when the advance commenced, within supporting distance of each other.

Before I arrived at Savannah, Sherman, who had joined the Army of the Tennessee and been placed in command of a division, had made an expedition on steamers convoyed by gunboats to the neighborhood of Eastport, thirty miles south, for the purpose of destroying the railroad east of Corinth. The rains had been so heavy for some time before that the low-lands had become impassable swamps. Sherman debarked his troops and started out to accomplish the object of the expedition; but the river was rising so rapidly that the back-water up the small tributaries threatened to cut off the possibility of getting back to the boats, and the expedition had to return without reaching the railroad. The guns had to be hauled by hand through the water to get back to the boats.

On the 17th of March the army on the Tennessee River consisted of five divisions, commanded respectively by Generals C. F. Smith, McClernand, L. Wallace, Hurlbut and Sherman. General W. H. L. Wallace was temporarily in command of Smith's division, General Smith, as I have said, being confined to his bed. Reinforcements were arriving daily and as they came up they were organized, first into brigades, then into a division, and the command given to General Prentiss, who had been ordered to report to me. General Buell was on his way from Nashville with 40,000 veterans. On the 19th of March he was at Columbia, Tennessee, eighty-five miles from Pittsburg. When all reinforcements should have arrived I expected to take the initiative by marching on Corinth, and had no expectation of needing fortifications, though this subject was taken into consideration. McPherson, my only military engineer, was directed to lay out a line to intrench. He did so, but reported that it would have to be made in rear of the line of encampment as it then ran. The new line, while it would be nearer the river, was yet too far away from the Tennessee, or even from the creeks, to be easily supplied with water, and in case of attack these creeks would be in the hands of the enemy. The fact is, I regarded the campaign we were engaged in as an offensive one and had no idea that the enemy would leave strong intrenchments to take the initiative when he knew he would be attacked where he was if he remained. This view, however, did not prevent every precaution being taken and every effort made to keep advised of all movements of the enemy.

Johnston's cavalry meanwhile had been well out towards our front, and occasional encounters occurred between it and our outposts. On the 1st of April this cavalry became bold and approached our lines, showing that an advance of some kind was contemplated. On the 2d Johnston left Corinth in force to attack my army. On the 4th his cavalry dashed down and captured a small picket guard of six or seven men, stationed some five miles out from Pittsburg on the Corinth road. Colonel Buckland sent relief to the guard at once and soon followed in person with an entire regiment, and General Sherman followed Buckland taking the remainder of a brigade. The pursuit was kept up for some three miles beyond the point where the picket guard had been captured, and after nightfall Sherman returned to camp and reported to me by letter what had occurred.

At this time a large body of the enemy was hovering to the west of us, along the line of the Mobile and Ohio railroad. My apprehension was much greater for the safety of Crump's landing than it was for Pittsburg. I had no apprehension that the enemy could really capture either place. But I feared it was possible that he might make a rapid dash upon Crump's and destroy our transports and stores, most of which were kept at that point, and then retreat before Wallace could be reinforced. Lew. Wallace's position I regarded as so well chosen that he was not removed.

At this time I generally spent the day at Pittsburg and returned to Savannah in the evening. I was intending to remove my headquarters to Pittsburg, but Buell was expected daily and would come in at Savannah. I remained at this point, therefore, a few days longer than I otherwise should have done, in order to meet him on his arrival. The skirmishing in our front, however, had been so continuous from about the 3d of April that I did not leave Pittsburg each night until an hour when I felt there would be no further danger before the morning.

On Friday the 4th, the day of Buckland's advance, I was very much injured by my horse falling with me, and on me, while I was trying to get to the front where firing had been heard. The night was one of impenetrable darkness, with rain pouring down in torrents; nothing was visible to the eye except as revealed by the frequent flashes of lightning. Under these circumstances I had to trust to the horse, without guidance, to keep the road. I had not gone far, however, when I met General W. H. L. Wallace and Colonel (afterwards General) McPherson coming from the direction of the front. They said all was quiet so far as the enemy was concerned. On the way back to the boat my horse's feet slipped from under him, and he fell with my leg under his body. The extreme softness of the ground, from the excessive rains of the few preceding days, no doubt saved me from a severe injury and protracted lameness. As it was, my ankle was very much injured, so much so that my boot had to be cut off. For two or three days after I was unable to walk except with crutches.

On the 5th General Nelson, with a division of Buell's army, arrived at Savannah and I ordered him to move up the east bank of the river, to be in a position where he could be ferried over to Crump's landing or Pittsburg as occasion required. I had learned that General Buell himself would be at Savannah the next day, and desired to meet me on his arrival. Affairs at Pittsburg landing had been such for several days that I did not want to be away during the day. I determined, therefore, to take a very early breakfast and ride out to meet Buell, and thus save time. He had arrived on the evening of the 5th, but had not advised me of the fact and I was not aware of it until some time after. While I was at breakfast, however, heavy firing was heard in the direction of Pittsburg landing, and I hastened there, sending a hurried note to Buell informing him of the reason why I could not meet him at Savannah. On the way up the river I directed the dispatch-boat to run in close to Crump's landing, so that I could communicate with General Lew. Wallace. I found him waiting on a boat apparently expecting to see me, and I directed him to get his troops in line ready to execute any orders he might receive. He replied that his troops were already under arms and prepared to move.

Up to that time I had felt by no means certain that Crump's landing might not be the point of attack. On reaching the front, however, about eight A.M., I found that the attack on Pittsburg was unmistakable, and that nothing more than a small guard, to protect our transports and stores, was needed at Crump's. Captain Baxter, a quartermaster on my staff, was accordingly directed to go back and order General Wallace to march immediately to Pittsburg by the road nearest the river. Captain Baxter made a memorandum of this order. About one P.M., not hearing from Wallace and being much in need of reinforcements, I sent two more of my staff, Colonel McPherson and Captain Rowley, to bring him up with his division. They reported finding him marching towards Purdy, Bethel, or some point west from the river, and farther from Pittsburg by several miles than when he started. The road from his first position to Pittsburg landing was direct and near the river. Between the two points a bridge had been built across Snake Creek by our troops, at which Wallace's command had assisted, expressly to enable the troops at the two places to support each other in case of need. Wallace did not arrive in time to take part in the first day's fight. General Wallace has since claimed that the order delivered to him by Captain Baxter was simply to join the right of the army, and that the road over which he marched would have taken him to the road from Pittsburg to Purdy where it crosses Owl Creek on the right of Sherman; but this is not where I had ordered him nor where I wanted him to go.
