Soon after Grant’s departure, Sherman withdrew from Shiloh Ridge, abandoning his camps and much of his equipment. He took a new position behind the Hamburg-Purdy Road alongside McClernand who had been pushed back on line with Prentiss’ Hornets’ Nest position.

Grant’s army was now posted on either side of Prentiss, making a line approximately 3½ miles long. The opposing army was charging this line with a series of frontal attacks, just as hard on the left as on the right. This was contrary to Johnston’s plan of battle. He had intended to push hardest on the Union left and seize their base of supplies at the Landing. Without supplies or an avenue of escape, he hoped to drive the disorganized Federals into the swamps of Snake and Owl Creeks and destroy them.

Seeing that the enemy was being driven into its base of supplies rather than away from it, Johnston, about noon, moved to the extreme right to direct in person the activities of that wing of his army. There, he found his troops exposed to a galling fire and unable to advance. Determined to move his line forward, Johnston ordered and led a successful charge. The Union lines recoiled, and the Confederates surged forward about three-fourths of a mile. As Johnston sat on his horse, watching the lines re-form, a ball from the gun of an unknown Union soldier struck the Southern commander, severing the large artery in his right leg. No surgeon being near, he died from loss of blood at 2:30 p. m.

The death of Johnston caused a lull in the battle on the right flank for about an hour. The situation was relieved somewhat by the fact that a second in command was on the field. Gen. Pierre G. T. Beauregard was in charge of headquarters which had been established near Shiloh Church. When informed of Johnston’s death, he immediately assumed command. He sent General Bragg to the right of the field and put Gen. Daniel Ruggles in command at the center.

General Ruggles, having witnessed 11 unsuccessful charges against the Hornets’ Nest, decided to concentrate artillery fire upon the position. Therefore, he collected all the artillery he could find—62 pieces—and opened fire upon the Union line. Under cover of continuous fire from these guns, the Confederates attacked with renewed courage and redoubled energy. Unable to withstand the assault, the troops on both the Federal right and left withdrew toward the Landing, leaving Prentiss and W. H. L. Wallace isolated in the Hornets’ Nest. As the Union forces withdrew, the left of the Confederate line swung around and joined flanks with the troops moving around from the right, thus forming a circle of fire around Wallace and Prentiss.

Wallace, seeing that the other divisions were withdrawing and that his command was being surrounded, gave the order for his troops to fall back. To execute the order, his division had to pass through a ravine which was already under the crossfire of the encircling Confederates. Wallace was mortally wounded in the attempt, but two of his regiments succeeded in passing through the valley, between the Confederate lines, which they appropriately named “Hell’s Hollow.” Prentiss continued the resistance until 5:30 p. m., when he was compelled to surrender with over 2,200 troops—all that remained of the two divisions.

During the afternoon, Col. Joseph D. Webster, Grant’s Chief of Artillery, placed a battery of siege guns around the crest of a hill about a quarter of a mile in from the Landing. The smaller field artillery pieces were put in position on either side of them as they were moved back from the front. The two wooden gunboats, Tyler and Lexington, anchored opposite the mouth of Dill Branch, further strengthened the line. As the remnants of the shattered Union Army drifted back toward the Landing, they were rallied along this line of cannon.

After the capture of Prentiss, an attempt was made to reorganize the Confederates for an attack upon the Union position near the Landing. Before a coordinated attack could be made, Beauregard, who had received word that Buell would not arrive in time to save Grant’s army, sent out the order from his headquarters at Shiloh Church to suspend the attack. Unknown to Beauregard, the advance of Buell’s army had already arrived opposite Pittsburg Landing and was being rapidly ferried across the river.

During Sunday night and Monday morning, Buell moved approximately 17,000 troops into line on the Union left. Lew Wallace put almost 6,000 fresh troops—Fort Donelson veterans—in position on the right. The Confederates, receiving no reinforcements, spent a sleepless night in the captured Union camps annoyed by shells from the gunboats, which were thrown among them at 15-minute intervals throughout the night.

The battle had already raged for 13 hours. Charge after charge had been made by the Confederates, followed by Federal countercharges. Ground had been gained and lost, but the general direction of movement had always been toward the Landing. By the time the day was over and the weary soldiers had lain down to rest, the Confederates were in possession of all the field, except the Landing and a bit of adjoining territory. Many Southern soldiers, in view of the gains made during the day, believed that the victory was already theirs. An equally large number of Northerners were willing to concede defeat. When night at last closed in around the hostile armies, feelings of uncertainty prevailed among the leaders on both sides. Many of them were well aware that the battle was yet to be won or lost.
