[Illustration: _Cherry Mansion, Savannah, Tenn., used as headquarters for the Union Army, March 13 to April 29, 1862. While eating breakfast in this house, General Grant heard the sounds of heavy firing which told him the battle had begun. Generals W. H. L. Wallace and C. F. Smith died here in April 1862._]
In obedience to this order, Sherman encamped his division along a ridge on either side of Shiloh Church, almost 3 miles from Pittsburg Landing, with General Hurlbut’s division about a mile to his rear. Within a few days, Gen. Benjamin M. Prentiss’ division took position on Sherman’s left, while Gen. John A. McClernand and Gen. W. H. L. Wallace formed their divisions between Sherman and the river. The 3d Division, commanded by Gen. Lew Wallace, was stationed at Crump’s Landing, about 4 miles downstream from the main encampment. Thus, by April 5, 1862, there were in the five divisions of the Army of the Tennessee at Pittsburg Landing 39,830 officers and men present for duty and 7,564 at nearby Crump’s Landing.
While this concentration of troops was in progress, General Smith received a leg injury which became so serious that he had to give up his command. General Grant was restored to duty and sent to Savannah with orders to concentrate troops and supplies, but to bring on no general engagement until a union could be made with Buell’s army, and Halleck had arrived to assume personal command of the combined forces.
General Johnston, in the meantime, was concentrating all available forces at Corinth, Miss., on the Memphis and Charleston Railroad. After this had been accomplished, he resolved to take the offensive and attack Grant’s army at Pittsburg Landing, hoping to defeat that army before it could be reinforced by General Buell. Hearing that Buell was nearing Savannah, Johnston determined to attack at once and accordingly on the 3d of April issued the order for the forward movement. He expected to give battle at daylight on April 5th, but heavy rains and bad roads made progress so slow that the last of his columns did not reach the field until late afternoon. It was then decided that the attack should be postponed until daylight the next morning. Johnston’s army, 43,968 strong, went into bivouac in order of battle within less than 2 miles of the Federal camps. The Confederate forces were formed in three lines. Gen. W. J. Hardee’s corps and one of Gen. Braxton Bragg’s brigades were in the first line, the remainder of Bragg’s corps in the second line, and Generals Leonidas Polk’s and J. C. Breckinridge’s corps in the third line.
