But their hopes were mingled with grave fears. General Van Dorn with an army of twenty thousand men was hastening from Arkansas to join the Confederate forces at Shiloh; but the roads were bad and he was yet far away. On the other hand, Buell was coming from Nashville to join Grant’s army. Should he arrive during the night, the contest of the next day would be unequal and the Confederates would risk losing all that they had gained. Moreover, Beauregard’s army, with its long, muddy march from Corinth and its more than twelve hours’ continuous fighting, was worn and weary almost to exhaustion.
The Union army was stunned and bleeding, but not disabled, at the close of the first day’s battle. Caught unawares, the men had made a noble stand. Though pressed back from their position and obliged to huddle for the night around the Landing, while thousands of their comrades had fallen on the gory field, they had hopes of heavy reënforcements during the night. And, indeed, early in the evening the cry ran along the Union lines that Buell’s army had come. The advance guard had arrived late in the afternoon and had assisted Hurlbut in the closing scene on the bluff of Dill’s ravine; others continued to pour in during the night. And, furthermore, General Lew Wallace’s division, though it had taken a wrong road from Crump’s Landing and had not reached the field in time for the fighting of the 6th, now at last had arrived. Buell and Wallace had brought with them twenty-five thousand fresh troops to be hurled on the Confederates on the morning of the 7th. But Van Dorn had not come. The preponderance of numbers now was with the Union army.
Everyone knew that the battle was not over, that the issue must be decided on the coming day, and the weary thousands of both sides sank down on the ground in a drenching rain to get a little rest and to gain a little strength for the desperate struggle that was sure to come on the morrow.
Beauregard rested hopes upon a fresh dispatch announcing that Buell was delayed and the dreaded junction of two Federal armies therefore impossible. Meanwhile Grant and Buell were together in Sherman’s camp and it was decided that Buell’s troops should attack Beauregard next morning. One division of Buell stood to arms all night.
At the break of day on Monday, April 7th, all was astir in both camps on the field of Shiloh, and the dawn was greeted with the roar of cannon. The troops that Grant now advanced into the contest were all, except about ten thousand, the fresh recruits that Wallace and Buell had brought, while the Confederates had not a single company that had not been on the ground the day before. Some military historians believe that Beauregard would have won a signal victory if neither army had been reënforced during the night. But now under the changed conditions the Confederates were at a great disadvantage, and yet they fought for eight long hours with heroic valor.
The deafening roar of the cannon that characterized the beginning of the day’s battle was followed by the rattle of musketry, so continuous that no ear could distinguish one shot from another. Nelson’s division of Buell’s army was the first to engage the Confederates. Nelson commanded the Federal left wing, with Hardee and Breckinridge immediately opposed to him. The Union center was under the command of Generals McCook and Crittenden; the right wing was commanded by McClernand, with Hurlbut next, while Sherman and Lew Wallace occupied the extreme right. The Confederate left wing was commanded by the doughty Bragg and next to him was General Polk.
Shiloh Church was again the storm center and in it General Beauregard made his headquarters. Hour after hour the columns in blue and gray surged to and fro, first one then the other gaining the advantage and presently losing it. At times the smoke of burning powder enveloped the whole field and hid both armies from view. The interesting incidents of this day of blood would fill a volume. General Hindman of the Southern side had a novel experience. His horse was struck by a bursting shell and torn to a thousand fragments. The general, thrown ten feet high, fell to the ground, but leaped to his feet unhurt and asked for another horse.
Early in the afternoon, Beauregard became convinced that he was fighting a losing battle and that it would be the part of prudence to withdraw the army before losing all. He thereupon sent the members of his staff to the various corps commanders ordering them to prepare to retreat from the field, at the same time making a show of resuming the offensive. The retreat was so skilfully made, the front firing-line being kept intact, that the Federals did not suspect it for some time. Some hours before nightfall the fighting had ceased. The Federals remained in possession of the field and the Confederates were wading through the mud on the road to Corinth.
It was a dreary march for the bleeding and battered Confederate army. An eye-witness described it in the following language:
“I made a detour from the road on which the army was retreating that I might travel faster and get ahead of the main body. In this ride of twelve miles alongside of the routed army, I saw more of human agony and woe than I trust I will ever again be called upon to witness. The retreating host wound along a narrow and almost impassable road, extending some seven or eight miles in length. Here was a line of wagons loaded with wounded, piled in like bags of grain, groaning and cursing; while the mules plunged on in mud and water belly-deep, the water sometimes coming into the wagons. Next came a straggling regiment of infantry, pressing on past the wagons; then a stretcher borne on the shoulders of four men, carrying a wounded officer; then soldiers staggering along, with an arm broken and hanging down, or other fearful wounds, which were enough to destroy life. And, to add to the horrors of the scene, the elements of heaven marshaled their forces—a fitting accompaniment of the tempest of human desolation and passion which was raging. A cold, drizzling rain commenced about nightfall, and soon came harder and faster, then turned to pitiless, blinding hail. This storm raged with violence for three hours. I passed long wagon trains filled with wounded and dying soldiers, without even a blanket to shelter them from the driving sleet and hail, which fell in stones as large as partridge eggs, until it lay on the ground two inches deep.
