The Battle of Shiloh or Pittsburg Landing was a two-day engagement in April 1862, when a Confederate army under Generals Albert Sidney Johnston and P.G.T. Beauregard launched a surprise attack on a Union army under the command of Major General Ulysses S. Grant.[1] Initially a Confederate victory by the end of the first day of fighting, it would turn into a Union victory by the end of the second day, but at a cost of a heavy amount of casualties.

Preliminary Campaign

War activity west of the Appalachian Mountains in 1861 was confined chiefly to the States of Kentucky and Missouri. Toward the end of the year when loyalty, or at least the neutrality, of the governments of these border States seemed assured, the Federals began making plans for the invasion of the South by way of the western rivers and railroads. Each side began to maneuver for strategic positions. The Confederate General, Leonidas Polk, believing that the Southern States were about to be invaded through Kentucky, moved up quickly from his position at Union City, Tenn., and seized Columbus, Ky., the northern terminus of the Mobile and Ohio Railroad. Gen. Ulysses S. Grant, recently appointed commander of the Federal troops in and around Cairo, Ill., had made preparations to occupy that important river port and railway center on the following day. Thwarted at Columbus, Grant retaliated by taking Paducah, Ky., located at the junction of the Tennessee and Ohio Rivers.

It now became apparent to the Confederate high command in Richmond that a strong line would have to be established along the northwestern border of the Confederacy before the Union armies had time to occupy more of the strategic points. They believed that the task could be performed more effectively if all troops in that theater of operation were placed under one commander. Accordingly, Confederate President Jefferson Davis sent Gen. Albert Sidney Johnston to the West with the imposing title of "General Commanding the Western Department of the Army of the Confederate States of America."

Arriving in Nashville on September 14, 1861, General Johnston studied his difficult assignment. The line he was supposed to occupy extended from the mountains of eastern Tennessee westward across the Mississippi to the Kansas boundary. Only two points on the proposed line were then in Confederate hands: Columbus, which he considered the natural key to the Confederate defense of the Mississippi, and Cumberland Gap, Ky., which he had previously ordered Gen. Felix K. Zollicoffer to occupy.

One of Johnston's first official acts upon arriving at Nashville was to order Gen. Simon B. Buckner to secure Bowling Green, Ky., one of the most important railroad centers south of the Ohio. He also ordered garrisons to the incomplete works at Fort Henry, on the Tennessee, and Fort Donelson, on the Cumberland, hoping to prevent a Union advance up either of these natural highways. A Federal offensive up the Tennessee or the Cumberland would endanger the important railroad and industrial center of Nashville, Tenn.

Since the outbreak of the war, Nashville had been converted into a huge arsenal and depot of supplies. Large quantities of food, clothing, and munitions had been collected and stored in its warehouses. Its factories were turning out percussion caps, sabers, muskets, saddles, harness knapsacks, cannon, and rifled pieces. Its looms were turning out thousands of yards of gray cloth which were being made into uniforms for the soldiers. The loss of this city would be an irreparable blow to the Confederacy.

While General Johnston was establishing his positions, the Federals were rapidly organizing their forces preparatory to an attack upon the Confederate line. Gen. Henry W. Halleck, from headquarters in St. Louis, was strengthening his positions at Cairo, Ill., and Paducah, Ky. At the same time, he was making ready a large number of river steamers so that his troops could be moved by water to almost any point along his front. From headquarters in Louisville, Gen. Don Carlos Buell, commander of the Department of the Ohio, reinforced his line so that Johnston had to keep his main force at Bowling Green, Ky., to guard the important railroads which penetrated Middle and West Tennessee.

Various plans for an attack upon the Confederate line were considered by the Federals. General Halleck, commander of the Department of the Missouri, believed that it would take an army of not less than 60,000 men, under one commander, to break the well-established line. He, therefore, asked that General Buell's army be transferred to him, or at least placed under his command.

Before a union of the two departments could be effected, General Grant asked for, and received, permission to attack the line at Fort Henry. A combined land and naval attack by Grant's troops and the gunboat fleet of Commodore Andrew H. Foote resulted in the surrender of Fort Henry on February 6, 1862, and the capture of Fort Donelson, with about 12,000 prisoners, on the 16th. The loss of these forts broke Johnston's line at its center and compelled him to evacuate Bowling Green and Columbus, permitting western Kentucky to fall into Union hands. To prevent encirclement, he was also forced to withdraw from Nashville, abandon Middle and West Tennessee, and seek a new line on the Memphis and Charleston Railroad.

Following the fall of Forts Henry and Donelson, Grant incurred the displeasure of General Halleck by sending a division of troops into Buell's department at Clarksville. Halleck's indignation increased when he learned that Grant had gone to Nashville for consultation with Buell. Halleck directed the withdrawal of the division from Clarksville suspended Grant from command, and ordered him to Fort Henry to await orders.

The army under Grant's successor, Gen. Charles F. Smith, moved up the Tennessee toward the heart of the Confederacy, with the intention of rendezvousing at Savannah, Tenn., on the east side of the river. Gen. William T. Sherman was sent forward on the so-called Yellow Creek Expedition for the purpose of destroying railroad communications to the west of Corinth, Miss., the objective of the campaign. High water made Sherman's mission a failure, and he was compelled to return. He reported to General Smith that a more convenient place for the assembling of his army was at Pittsburg Landing, Tenn., 9 miles above Savannah, and on the west side of the river, from which direct roads led to Corinth. General Smith, therefore, instructed him to disembark his division and that of Gen. Stephen A. Hurlbut at Pittsburg Landing, in positions far enough back to afford room for the other divisions of the army to encamp near the river.

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. MeClernand 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 5, 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.

During the night of April 5 the two hostile armies were encamped within a short distance of each other: the Confederates poised, ready to attack, while the unsuspecting Union army went about its normal camp routine, making no preparations for the defense of its position. On Saturday, a few hours before the battle, Sherman wrote Grant: "I have no doubt that nothing will occur to-day more than some picket firing," and that he did not "apprehend anything like an attack" on his position. The same day, after Sherman's report from the front, Grant, who was at Savannah, telegraphed Halleck: "I have scarcely the faintest idea of an attack (general one) being made upon us, but will be prepared should such a thing take place."

The First Day

The battle began about 4:55 a. m., Sunday, April 6, when a reconnoitering party of Prentiss' Union division encountered Hardee's skirmish line, under Maj. Aaron B. Hardcastle, a short distance in front of Sherman's camps. The reconnoitering party—three companies of the 25th Missouri under Maj. James E. Powell—fighting and retreating slowly toward its camps was reinforced by four companies of the 16th Wisconsin and five companies of the 21st Missouri. These troops were, in turn, reinforced at the northeast corner of Rhea Field by all of Col. Everett Peabody's brigade. Here they succeeded in holding the Confederates in cheek until about 8 a. m., when they fell back to Prentiss' line of camps, closely followed by the enemy.

General Sherman, hearing the picket firing in his front, immediately got his division under arms and posted a battery at Shiloh Church and another on the ridge to the south. The left of this hastily formed line received the full impact of the Confederate onslaught at about the same time that Prentiss' camps were attacked. One of the regiments in the left brigade—the 53d Ohio—consisted of raw troops who had never been under fire. Unable to withstand the fierce Confederate attack, this regiment soon broke and fled to the rear. A short time later the other two regiments of the brigade did likewise. The commander of the brigade, Col. Jesse Hildebrand, refused to leave the field with his men. Since he had no troops of his own, he acted as aide for General MeClernand the rest of the day.

General Prentiss, in the meantime, was making a gallant, but futile, stand along his line of camps. Assailed by the eager Confederates in front and on the flanks, his whole division soon broke and fell back in confusion. He succeeded in rallying about 1,000 of his men on the center of a line that W. H. L. Wallace and Hurlbut were forming with parts of their divisions in a strong position in the rear. This new line, running through a densely wooded area along an old sunken road, proved to be such a strong position that the Confederates named the place "Hornets' Nest" because of the stinging shot and shell they had to face there.

Meanwhile, General Grant at breakfast in Savannah heard the guns in the battle of Shiloh. He at once sent word to the advance of Buell's army, which had already arrived at Savannah, to march immediately to the point on the river opposite the battlefield. He then hurried up the river aboard the steamer Tigress, moving in close enough to the shore at Crump's Landing to instruct Gen. Lew Wallace to be prepared to execute any order he might receive. Upon arriving at the field, he dispatched reinforcements to Prentiss and formed two regiments in line near Pittsburg Landing, to arrest the tide of stragglers from the battle and organize them to return. He then rode to the front.

While the Confederate right was engaged with Prentiss, the left, supported by continuous artillery fire, was hurled against the combined forces of Sherman and MeClernand who were making a stubborn stand along the ridge at Shiloh Church. This small log building, which gave its name to the battle, was considered the key position of the field, as it commanded the best road from Corinth to Pittsburg Landing. When General Grant reached the church, about 10 a. m., his troops were heavily engaged all along the line. They had resisted the relentless pounding from the Confederate artillery and the repeated infantry charges for over 2 hours. Seeing that the line could not hold much longer, Grant dispatched orders to Lew Wallace to move to the field, expecting him to reinforce the Union right. Leaving Sherman, he moved down the line to the left to confer with his other division commanders. He visited Prentiss in the Hornets' Nest and directed him to hold his position there at all hazards.

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 MeClernand 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 3-1/2 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., becoming the first American general officer to die in battle.

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 gun boats, 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.

The Second Day

Monday morning, April 7, at daylight, the vanquished of the previous day renewed the struggle with increased strength and restored confidence. Anxious to take the initiative the Union armies were put in motion almost simultaneously, with Buell on the left, Lew Wallace on the extreme right, and Grant's weary troops occupying the space between. The movement began unopposed, except by small unsupported parties which were quickly forced to retreat.

The Confederates had been unable to reorganize their widely scattered forces during the night. Therefore, when the Union advance began on Monday the opposing line of battle was yet unformed. The Confederates were still back in the vicinity of the captured Union camps vainly trying to reorganize their broken commands. They did not succeed in forming a line until after the enemy had advanced beyond the Peach Orchard and the Hornets' Nest, regaining much of the territory they had lost the day before.

The Confederates, one brigade strong, were first encountered by Lew Wallace a short distance in front of his Sunday night bivouac. In a brief but spirited engagement, the Confederates were attacked in front and on the left flank by the Union division. To keep from being surrounded, they fell back almost a mile in the direction of Shiloh Church to take their place in the forming line of battle.

In the meantime, Buell moved his troops rapidly forward until they developed the Confederate line of battle west of the Peach Orchard. The Southerners boldly charged the advancing Union infantry which had moved forward so rapidly that its artillery was still far to the rear. With out artillery support, the Federals were unable to withstand the violent assault of the Confederates and were forced to make a hasty retreat. The timely arrival and effective use of two batteries of artillery permitted the Union line again to advance, only to be driven back once more by the stubborn Confederates.

The battle now raged the entire length of the field. Charge followed by countercharge moved the fitfully swaying line first toward the river and then toward the church. The advantage would seem to test momentarily with the weary Southerners, but would soon be lost to their greatly strengthened opponent. Commands became so intermingled and confused that it was often impossible to distinguish between friend and foe. The Confederates, clad in a variety of colored uniforms, with no well-defined line and on an ever-changing front, suffered the heavier losses from the fire of their own troops.

Meanwhile, General Beauregard, at Shiloh Church, anxiously awaited the return of couriers he had dispatched to Corinth to hurry forward Gen. Earl Van Dorn's army of about 20,000 men, daily expected there from Van Buren, Ark. He had promised to make a junction with General Beauregard as soon as possible, but was delayed because he had no means of transporting his troops across the Mississippi. Unaware that Van Dorn was still in Arkansas, General Beauregard maintained his largest troop concentration in the vicinity of the church to defend the Corinth-Pittsburg Road so that reinforcements could be quickly moved onto the field. As soon as it became known that additional troops were not on the way, Beauregard realized that the road would have to be kept open as a possible line of retreat. The Union commanders were equally determined to drive the Confederates from the position. Consequently, furious fighting raged before the church long after the tempo of the battle had slackened on each flank.

Despite all efforts of the Confederates, the Union line continued slowly to advance. In desperation the Confederates made a gallant charge, first expending their ammunition and then relying on the bayonet. The charge carried the surging line through waist-deep Water Oaks Pond, beyond which the fire from the adversary became so strong that the line was brought to an abrupt halt. Taking cover at the edge of a woods, they repulsed every attempt by the Federals to advance.

By 2 p. m. General Beauregard decided it was useless to prolong the unequal struggle. Since early morning, his lines had been forced back, step by step, with heavy losses. From all parts of the field his subordinates were sending urgent requests for reinforcements, which he was unable to supply. Even his position at the church was in danger of being taken. A continuation of the battle could bring only additional disasters upon his already greatly depleted ranks. To forestall a complete rout, he ordered a rear guard with artillery support to be put in position on the ridge west of the church and instructed his corps commanders to begin withdrawing their troops. By 4 o'clock, the last of the Confederate Army, or what was left of it, had retired from the field and was leisurely making its way back to Corinth without a single Federal soldier in pursuit.

The Union armies did not attempt to harass the retreating Southern columns or attack them when they went into bivouac for the night. Instead, Grant's troops, from the privates to the highest commanders, appear to have been content to return to their recaptured camps, while the Confederates returned to their former positions in and around Corinth to recruit and reorganize.

In explanation of his inactivity Grant said: "My force was too much fatigued from two days' hard fighting and exposure in the open air to a drenching rain during the intervening night, to pursue immediately. Night closed in cloudy and with heavy rain, making roads impracticable for artillery by the next morning."

The next morning, April 8, however, Gen. Thomas J. Wood, with his division, and Sherman, with two brigades and the 4th Illinois Cavalry, went in pursuit. Toward evening they came upon the Confederate rear guard at Fallen Timbers, about 6 miles from the battlefield. The Southern cavalry, commanded by Col. Nathan Bedford Forrest, charged the Federals, putting the skirmishers to flight and throwing the Union cavalry into confusion. The Confederates, pursuing too vigorously, came suddenly upon the main body of Federal infantry and were repulsed, after Colonel Forrest had been seriously wounded in the side. Before returning to camp, the Northerners tarried long enough to bury their 15 dead, gather up their 25 wounded, and find out that they had lost 75 as prisoners. The spirited action of the Confederate rear guard at Fallen Timbers put an end to all ideas of further pursuit by the Federals.


The losses on each side at Shiloh were unusually heavy. Grant's army of 39,830 had been reinforced by 25,255 during the night between the 2 days' battle, swelling the total number of Union troops engaged to 65,085, excluding a guard detachment of 1,727 men left at Crump's Landing. Of that total number 1,754 were reported killed, 8,408 wounded, and 2,885 missing; presenting an aggregate of 13,047 casualties. The Southerners lost 1,728 killed, 8,012 wounded, and 959 captured or missing, or a total of 10,699 casualties. The total number of battlefield casualties - 23,746 men - exceeded the number of casualties from all previous American wars combined, and left a sobering reminder that worse was yet to come.

During the first few weeks following the battle, both sides claimed a victory. The Confederates based their claim upon the facts that they had inflicted an almost complete rout on the Federals on Sunday, April 6, and that they had been able to hold a part of the field until they withdrew in good order on Monday. Furthermore, they said, the Union armies were so battered that they were unable to pursue.

The Federals claimed the victory upon the grounds that on Monday evening they had recovered their encampments and had possession of the field from which the Confederates had retired, leaving behind a large number of their dead and wounded. But Grant's image would suffer a temporary setback. Accused of being a butcher as well as being a drunk, Grant would spend much of the following months as second in command to Halleck; calls for his removal were shut down by Lincoln: "I can't spare this man." the president said. "He fights."

After the Battle of Shiloh the Confederates were compelled to withdraw southward. Corinth was abandoned to the North on May 30, severing the railroad from Memphis to Chattanooga. By the end of June 1862, only those forts on the Mississippi River near Vicksburg remained in Southern hands.
