Some two or three miles from Pittsburg landing was a log meeting-house called Shiloh. It stood on the ridge which divides the waters of Snake and Lick creeks, the former emptying into the Tennessee just north of Pittsburg landing, and the latter south. This point was the key to our position and was held by Sherman. His division was at that time wholly raw, no part of it ever having been in an engagement; but I thought this deficiency was more than made up by the superiority of the commander. McClernand was on Sherman's left, with troops that had been engaged at forts Henry and Donelson and were therefore veterans so far as western troops had become such at that stage of the war. Next to McClernand came Prentiss with a raw division, and on the extreme left, Stuart with one brigade of Sherman's division. Hurlbut was in rear of Prentiss, massed, and in reserve at the time of the onset. The division of General C. F. Smith was on the right, also in reserve. General Smith was still sick in bed at Savannah, but within hearing of our guns. His services would no doubt have been of inestimable value had his health permitted his presence. The command of his division devolved upon Brigadier-General W. H. L. Wallace, a most estimable and able officer; a veteran too, for he had served a year in the Mexican war and had been with his command at Henry and Donelson. Wallace was mortally wounded in the first day's engagement, and with the change of commanders thus necessarily effected in the heat of battle the efficiency of his division was much weakened.
The position of our troops made a continuous line from Lick Creek on the left to Owl Creek, a branch of Snake Creek, on the right, facing nearly south and possibly a little west. The water in all these streams was very high at the time and contributed to protect our flanks. The enemy was compelled, therefore, to attack directly in front. This he did with great vigor, inflicting heavy losses on the National side, but suffering much heavier on his own.
The Confederate assaults were made with such a disregard of losses on their own side that our line of tents soon fell into their hands. The ground on which the battle was fought was undulating, heavily timbered with scattered clearings, the woods giving some protection to the troops on both sides. There was also considerable underbrush. A number of attempts were made by the enemy to turn our right flank, where Sherman was posted, but every effort was repulsed with heavy loss. But the front attack was kept up so vigorously that, to prevent the success of these attempts to get on our flanks, the National troops were compelled, several times, to take positions to the rear nearer Pittsburg landing. When the firing ceased at night the National line was all of a mile in rear of the position it had occupied in the morning.
In one of the backward moves, on the 6th, the division commanded by General Prentiss did not fall back with the others. This left his flanks exposed and enabled the enemy to capture him with about 2,200 of his officers and men. General Badeau gives four o'clock of the 6th as about the time this capture took place. He may be right as to the time, but my recollection is that the hour was later. General Prentiss himself gave the hour as half-past five. I was with him, as I was with each of the division commanders that day, several times, and my recollection is that the last time I was with him was about half-past four, when his division was standing up firmly and the General was as cool as if expecting victory. But no matter whether it was four or later, the story that he and his command were surprised and captured in their camps is without any foundation whatever. If it had been true, as currently reported at the time and yet believed by thousands of people, that Prentiss and his division had been captured in their beds, there would not have been an all-day struggle, with the loss of thousands killed and wounded on the Confederate side.
With the single exception of a few minutes after the capture of Prentiss, a continuous and unbroken line was maintained all day from Snake Creek or its tributaries on the right to Lick Creek or the Tennessee on the left above Pittsburg.
There was no hour during the day when there was not heavy firing and generally hard fighting at some point on the line, but seldom at all points at the same time. It was a case of Southern dash against Northern pluck and endurance. Three of the five divisions engaged on Sunday were entirely raw, and many of the men had only received their arms on the way from their States to the field. Many of them had arrived but a day or two before and were hardly able to load their muskets according to the manual. Their officers were equally ignorant of their duties.
Under these circumstances it is not astonishing that many of the regiments broke at the first fire. In two cases, as I now remember, colonels led their regiments from the field on first hearing the whistle of the enemy's bullets. In these cases the colonels were constitutional cowards, unfit for any military position; but not so the officers and men led out of danger by them. Better troops never went upon a battle-field than many of these, officers and men, afterwards proved themselves to be, who fled panic stricken at the first whistle of bullets and shell at Shiloh.
