Shiloh (the United States)
The Battle of Shiloh (also known as the Battle of Pittsburg Landing) was fought on April 6–7, 1862, in the American Civil War. The fighting took place in southwestern Tennessee, which was part of the war's Western Theater. The battlefield is located between a church named Shiloh and Pittsburg Landing, which is on the Tennessee River. Two Union armies combined to defeat the Confederate Army of Mississippi. Major General Ulysses S. Grant was the Union commander, while General Albert Sidney Johnston was the Confederate commander.
The Confederate army hoped to defeat Grant's Army of the Tennessee before it could be reinforced and resupplied. Although it made considerable gains with a surprise attack during the first day of the battle, Johnston was mortally wounded and Grant's army was not eliminated. Overnight, Grant's Army of the Tennessee was reinforced by one of its divisions stationed farther north, and it was also joined by portions of the Army of the Ohio. This second Union army was commanded by Major General Don Carlos Buell. The Union forces conducted an unexpected counterattack in the morning, which reversed the Confederate gains of the previous day. The exhausted Confederate troops withdrew further south, and a modest Union pursuit started and ended on the next day.
Though victorious, the Union army had more casualties than the Confederates, and Grant was heavily criticized. Decisions made on the battlefield by leadership on both sides were questioned, often by those that were not present for the fighting. The battle was the costliest engagement of the Civil War up to that point, and its nearly 24,000 casualties made it one of the bloodiest battles in the entire war. Ironically, the name of the church for which the battle is named translates to "place of peace".
During February 1862, a Union army led by Ulysses S. Grant won two battles that were the most significant Union victories, at that time, of the American Civil War. The battles were the Battle of Fort Henry and the Battle of Fort Donelson, and they occurred in Tennessee on the Tennessee River and the Cumberland River, respectively. Those rivers were vital to the Confederacy as transportation routes, and they also connected the city of Nashville, an ironworks, and major agricultural areas. Nashville was a converging point for railroads, a major producer of gunpowder, and a major supply depot. The Union army increased its firepower in those battles by receiving assistance from U.S. Navy gunboats. The steam-powered gunboats were flat-bottomed, armored, and carried up to 13 artillery pieces. Grant was rewarded for his success by a promotion to major general, making him senior to all generals in the Western Theater (between the Appalachian Mountains and Mississippi River) with the exception of Major General Henry Halleck.
Continuing their push into Confederate territory, Union troops arrived at the Tennessee River town of Savannah, Tennessee, on March 11. By mid-March, a large number of Union troops were camped there and at landings further south, and additional Union troops under the command of Don Carlos Buell were moving from Nashville to join the force on the river. Union leadership realized that its troops were too spread out, so it was decided to concentrate troops at Pittsburg Landing. Pittsburg Landing is nine miles (14 km) upriver (south) of Savannah, and it had a road that led to Corinth, Mississippi. About three miles (4.8 km) inland from the landing was a log church named Shiloh. The Hebrew word "shiloh" translates to "place of peace". The region that would become the Shiloh battlefield was somewhat shaped like a triangle, with the sides formed by various creeks and the Tennessee River. The land was mostly wooded, with scattered cotton fields, peach orchards, and a few small structures.
The Confederate Army's February 6 loss at Fort Henry caused it to abandon Kentucky and parts of Tennessee. The last Confederate troops in Nashville moved south on February 23. General Albert Sidney Johnston, Confederate commander of the Western Theater, made the decision to make the controversial abandonment. Although Confederate politicians were unhappy with Johnston's performance and the abandonment, the consolidation of troops further south was a wise choice because the Union forces on the Tennessee River could cut off Confederate retreats from posts in Kentucky and major portions of Tennessee. Confederate leadership decided to consolidate forces in Corinth, Mississippi, which is just south of the Tennessee–Mississippi border. The town of Corinth had a strategic value because it was at the intersection of two railroads, including one that was part of the rail network used to move Confederate supplies and troops between Tennessee and Virginia. By the end of March, over 40,000 Confederate troops were concentrated at Corinth.
The Union plan was to combine Grant's and Buell's armies and continue its southward offensive. If the combined armies could move south and capture Corinth, they would have a good starting point for the capture of Memphis, Vicksburg, and large portions of Confederate territory. While most of Grant's army camped near the river at Pittsburg Landing in early April, one division was five miles (8.0 km) downstream (north) at Crump's Landing, and army headquarters remained further north in Savannah. Buell's army was moving south from Nashville to Savannah, and no advancement beyond the Pittsburg Landing-Shiloh area was allowed until the two armies combined.[Note 1] On April 4, Confederate cavalry was seen by a Union patrol near Shiloh, but Union leadership was not concerned.
Confederate leaders realized they could soon be outnumbered. They had 42,000 men at Corinth, and 15,000 more on the way, while the not–yet–combined Union force could be as large as 75,000 men.[Note 2] Instead of waiting to be attacked by a larger force, they decided to surprise the Union Army on April 4 before the second Union Army arrived from Nashville. Inexperience and bad weather caused their 20-mile (32 km) march north to be "a nightmare of confusion and delays", and the Confederate Army was not deployed into position until the afternoon of April 5. The army spent the night of April 5 on the south side of the Union campsites. The plan was to attack the Union left, pushing it northwest against the swampy land adjacent to Snake and Owl creeks. Confederate troops along the Tennessee River would prevent Union reinforcements and resupply.

The two Union armies in the Battle of Shiloh were part of the Department of the Mississippi, which was commanded by Major General Henry Halleck. Although Halleck hoped to lead the two armies in an eventual attack on Corinth, he was not present at Shiloh. The combined armies present for the battle totaled to 66,812 men.[Note 3] The majority of the Union soldiers were armed with either a .69 caliber model 1841 rifled musket or a .69 caliber model 1842 smoothbore musket, although a few regiments had more modern weapons such as the .58 caliber Springfield Model 1855. A few regiments, or sometimes a few companies within a regiment, had Enfield or Austrian rifles. The armies and their divisions were organized as follows:
The Army of the Tennessee had the most Union men present at the battle, and it was commanded by Major General Ulysses S. Grant. In February 1862, a smaller version of Grant's army, with the assistance of gunboats under the command of Flag-Officer Andrew H. Foote, was the victor in the Battle of Fort Henry and the Battle of Fort Donelson.[Note 4] For the Battle of Shiloh, Grant's army had 48,894 men in six divisions. Two new divisions (4th and 5th) were added to Grant's three in early March. A 6th Division was created from reinforcement units at the beginning of April. The divisions (and gunboats) were as follows:
The other Union army at the Battle of Shiloh was the Army of the Ohio, which was commanded by Major General Don Carlos Buell. Portions of this army did not participate in the battle. One portion remained in Nashville, and another portion moved toward Murfreesboro and northern Alabama. Another division, plus part of a second one, did not arrive in time to participate in the battle. The number of men present at the battle totaled to 17,918. Although none of the regiments in Buell's army had participated in a major battle, all were well-trained and well-equipped. The divisions in the battle were:
Further information: Confederate order of battle
The Confederate army at the Battle of Shiloh was called the Army of Mississippi, and it was commanded by General Albert Sidney Johnston. This army was created by combining the scattered divisions of Johnston's army with troops from Mobile and New Orleans. Johnston's second in command was General Pierre G. T. Beauregard. Including one regiment that arrived on April 7, this army had 44,699 men present for duty. The forces at the battle were:
Most of the Confederate troops did not have combat experience, and regiments were smaller than normal. Bragg's Second Corps was the largest of four corps, although it was smaller than the normal size. One of the reasons for the four small corps (instead of fewer corps that were larger) was size deception, as a typical corps had about 20,000 men. Small arms included flintlocks, shotguns, squirrel rifles, and percussion muskets. A few thousand of the highly accurate Enfield rifles were distributed to Johnston's men before the battle. The Confederate supply of Enfield rifles increased when they were seized from Union troops in the battle. Only one-third of the cavalry possessed any weapons at the start of the battle. Confederate cavalry was much more effective than their Union counterpart, and enabled Johnston to know the positions of both Union armies.
Early Sunday morning on April 6, five of Grant's six divisions were camped between the Shiloh Church area and the Tennessee River. Sherman's division was the first to occupy the Shiloh area, so his four brigades were camped near the main approaches to Pittsburg Landing. Colonel David Stuart's brigade was on the Union left (east side of battlefield) near the Hamburg-Savannah Road and a ford. To the west in the Shiloh Church area, Sherman's other three brigades formed the Union right. They covered the Pittsburg–Corinth Road and the Owl Creek Bridge over the Hamburg–Purdy Road. In between Sherman and Stuart was Prentiss's division, and between the Shiloh Church area and the Tennessee River were the divisions of McClernand and Hurlbut. To the north and closest to Pittsburg Landing was W.H.L. Wallace's division. Lew Wallace's division was at Crump's Landing, five miles (8.0 km) downstream (north) of the Union campsites, to guard against a Confederate attack from behind. Grant was further north at his headquarters in Savannah. Nelson's division from Buell's army had reached Savannah, but Buell's other divisions were still marching.
The Shiloh camps did not form a defensive line, and no entrenchments were made because nobody expected a fight at that location. The divisions of Sherman and Prentiss were the most forward (closest to Corinth) of the group. Only a few pickets were in place—despite a small skirmish taking place on April 4.[Note 5] After hearing reports concerning sightings of Confederate soldiers in the Shiloh area, Colonel Everett Peabody, commander of the First Brigade from Prentiss's division, became concerned. Around midnight on April 5, Peabody ordered Major James E. Powell to take three companies of the 25th Missouri Infantry Regiment, and two companies of the 12th Michigan Infantry Regiment, on a reconnaissance (a.k.a. scout) to Seay Field where the sighting had been made. Prentiss was not informed, and Powell's men advanced from their camp southwest down a farm road that led to the Pittsburg-Corinth Road.
The Confederate Third Brigade of Hardee's Third Corps was southwest of Powell's patrol. The brigade was commanded by Brigadier General S. A. M. Wood, and he had sent forward 280 skirmishers from Major Aaron B. Hardcastle's Third Mississippi Battalion. Hardcastle kept most of his men in the southeast corner of James J. Fraley's 40-acre (16 ha) cotton field, while two sets of pickets were positioned closer to the Union camps. Around 5:00 am (April 6), Confederate pickets fired at Powell's men before returning to the battalion. When Powell advanced within 200 yards (180 m) of Hardcastle's main force, the Confederates opened fire. The Battle of Shiloh began with these two small forces fighting for over an hour. The battle has also been called the Battle of Pittsburg Landing.[Note 6]
Around 5:30 am, Confederate leaders heard the commotion at Fraley Field, and Johnston ordered a general attack. Johnston instructed Beauregard to stay in the rear and direct men and supplies as needed. Johnston rode to the front to lead the men on the battle line, and this arrangement effectively ceded control of the battle to Beauregard.[Note 7] On the Union side, Powell sent a message to Colonel Peabody that he was being driven back by an enemy force of several thousand. Hearing the fighting, Prentiss soon learned that Peabody had sent out a patrol without authorization. Prentiss was outraged and accused Peabody of provoking a major engagement in violation of Grant's orders. However, he soon understood that he was facing a large Confederate force and sent reinforcements. Peabody's patrol, with Powell leading, partially ruined the planned Confederate surprise and gave thousands of Union soldiers time (although brief) to prepare for battle. Although Peabody's patrol had alerted the Union army, some Union leaders were not convinced that they were under attack. Sherman was not convinced until he was slightly wounded, and one of his orderlies shot dead, after a 7:00 am ride to investigate the commotion near Rea Field.
After Johnston's 5:30 order for a general attack, it took an hour before all Confederate troops were ready. Another hour was lost skirmishing at Seay Field (close to Fraley Field). This reduced the Confederate advantage from the unexpected attack. The Confederate army alignment was another issue that helped reduce the attack's effectiveness. The corps of Hardee and Bragg began the assault with their divisions in one line that was nearly 3 miles (4.8 km) wide. At about 7:30 am Beauregard ordered the corps of Polk and Breckinridge forward on the left and right of the line, which only extended the line and diluted the effectiveness of the two attacking corps. It became impossible to control the intermingled units, so the corps commanders decided to divide the battlefield, and each commander led their battlefield portion instead of their own corps. The attack went forward as a frontal assault. Johnston and Beauregard did not put more strength on the east side, which meant they did not focus on their objective of turning the Union left.
Sherman and Prentiss were the commanders of the first two Union divisions attacked, and those happened to be the most inexperienced of Grant's six divisions. Sherman, who had been negligent in preparing for an attack, performed with "coolness and courage" while he inspired his raw troops.[Note 8] Facing artillery fire and a frontal attack from the corps of Hardee, Bragg, and Polk, Sherman's men performed reasonably well—if they fought. An inexperienced colonel from the 53rd Ohio Infantry Regiment yelled "retreat and save yourselves", and many from his regiment simply ran away. Eventually, at least two companies of the calmer men from this regiment attached to another regiment. Sherman slowly moved the division back to a position behind Shiloh Church. He became supported on his left by the Third Brigade from McClernand's division.
Prentiss had his camps northeast of Seay Field. On his right, his brigade commanded by Peabody was attacked by two Confederate brigades, and Peabody was wounded four times before being killed. By 8:30 am, the remnants of Peabody's brigade were pushed north, and the Confederate army occupied his camp. Further east, Prentiss's other brigade was attacked by brigades commanded by Brigadier General Adley H. Gladden and Brigadier General James R. Chalmers. Around 8:45 am, Gladden was mortally wounded from cannon fire. The Confederate troops suffered considerable casualties, especially from artillery fire. However, the Confederate troops pushed on, and captured the remaining 6th Division camp sometime near 9:00 am. The Confederate soldiers had seen many of the Union soldiers running away from the front line, and now possessed the Union camps of Sherman and Prentiss. Looting became a problem, as Confederate soldiers found clothing, rifles, and food. Confederate leaders found it difficult to control their forces. They paused their attack, which enabled Prentiss to move further north.
East of McClernand, Hurlbut had all three brigades ready for action at 8:00 am. After being notified that Sherman was facing a strong attack on his left, Hurlbut sent his Second Brigade, commanded by Colonel James C. Veatch, to assist Sherman. Shortly after that first message, Hurlbut was advised that Prentiss was in trouble. Hurlbut brought his remaining two brigades south on the Hamburg-Savanah Road near Wicker Field, and he encountered a large number of panic-stricken men from Prentiss's division who were fleeing north. Unable to stop the retreat, he settled his brigades further south near a peach orchard.
Grant was in Savannah having breakfast at his Cherry Mansion headquarters when he heard the distant sounds of artillery fire. He was on crutches as he recovered from a fall from his horse, and he was waiting for more of Buell's army to arrive in Savannah.[Note 9] Grant ordered Bull Nelson to march his division along the east side of the river to a point opposite Pittsburg Landing, where it could be ferried over to the battlefield. Grant then took his steamboat, Tigress, south to Crump's Landing, where he told Lew Wallace to get his division ready to move. Grant proceeded to Pittsburg Landing, arriving around 9:00 am.[Note 10] The landing was beginning to accumulate men who had fled their posts, and Grant ordered a colonel to halt all stragglers. He then rode inland and confirmed that the Confederates had launched a full-scale attack instead of a probing action. He sent a message to Crump's Landing, ordering Lew Wallace to bring his division to the battlefield.[Note 11]
After the beginning of the battle, Brigadier General W.H.L. Wallace sent his Second Brigade, commanded by Brigadier General John McArthur, to fill a gap on the Union left between Hurlbut's position at a peach orchard and Stuart's brigade at the extreme Union left. McArthur had only two of his regiments, since the others had been sent to assist Sherman and guard the Snake River bridge that led to Crump's Landing. His two–regiment force was bolstered by Battery A from the 1st Illinois Light Artillery Regiment. Wallace's First and Third brigades, commanded by Colonel James M. Tuttle and Colonel Thomas W. Sweeny, respectively, moved into positions near Duncan Field and what is now called the "Sunken Road"—between the divisions of McClernand and Hurlbut. From 9:30 am to 10:30 am, most of the fighting at this position was the exchange of artillery fire.
On the extreme Union left, Stuart's brigade had heard musket firing early in the morning, but did not believe they were under attack until they heard distant artillery fire. At 9:30 am Johnston received reports that Union soldiers were deploying on the Confederate right flank. To remedy this potential problem, he sent two brigades from Bragg's Corps, and called up Breckenridge's Reserve Corps. What his scouts had actually found was the camp belonging to Stuart's Brigade. Stuart was near the Hamburg-Savannah Road close to Lick Creek. Around 9:40 am Stuart began receiving artillery fire, and twenty minutes later his men were attacked by Confederate infantry.
Shortly after 10:00 am, the remnants of Sherman's division established a new position further north from Shiloh Church. This position was near a crossroads of the Hamburg–Purdy Road with the Pittsburg–Corinth Road. By this time, Sherman's Third Brigade (three Ohio regiments) was eliminated, as its last intact regiment ran away. Colonel Jesse Hildebrand, the brigade commander, remained on the field as a volunteer aide for McClernand's headquarters. Sherman's First Brigade, commanded by Colonel John A. McDowell was west on the Hamburg–Purdy Road and cut off. Colonel Ralph P. Buckland's Fourth Brigade was fragmented and ammunition was low.
Sherman prepared a defense with the men he had left, including Colonel Julius Raith's Third Brigade from McClernand's division that had reinforced Sherman's left earlier. Sherman also had the 6th Indiana Artillery Battery commanded by Captain Frederick Behr, and part of a battery from McClerndon. For the first time, the Union army had a continuous front. From west to east were the remnants of Sherman's division, McClernand, W.H.L. Wallace, the remnants of Prentiss's division, Hurlbut, McArthur's brigade from W.H.L. Wallace's division, and Stuart's brigade from Sherman's division. Hurlbut was near a peach orchard, Prentiss was near the Sunken Road, and W.H.L. Wallace was adjacent to Duncan Field at the Sunken Road.
After a failed attack and the addition of more men, the Confederates attacked Sherman and McClernand again at 11:00 am. This Confederate attacking force consisted of portions of seven brigades. The Union losses in this attack included Colonel Raith, who was mortally wounded, and Behr's battery which fled to the rear after Behr was shot dead. On the Confederate side, Wood's brigade took heavy losses, but routed the brigade of Colonel C. Carroll Marsh from McClernand's division. Wood's men then defeated Veatch's brigade, but Wood was thrown from his horse and temporarily out of action. At that time, his brigade became scattered and disorganized. By 11:20 am, the Confederate army controlled the Hamburg-Purdy Road. Benefitting from the exhaustion and disorganization of the Confederate force, Sherman and McClernand fell back about 200 yards (180 m) north of the crossroads. Sherman's separated First Brigade (McDowell) linked with McClernand around 11:30 am.
The Sunken Road was an old wagon track called "an abandoned road" in the only time it was mentioned in the Official Records. From west to east, it ran from Duncan Field to a peach orchard (eventually known as "the Peach Orchard") at the Hamburg-Savanah Road. The old wagon track was so worn and washed–over that it had an embankment that ranged from a few inches (7.6 cm) to supposedly three feet (0.91 m). This ready-made entrenchment received the name "Sunken Road" in post-war years. Some historians doubt that the road was actually sunken. Nothing in the Official Records mentions it as sunken, and the soldier who wrote in his diary that the road was about three feet deep was is a regiment that was not close enough to the road to see it. When the fighting later became heated in this area—Duncan Field, the Sunken Road, and the woods on the north side of the road—the Confederates began calling it the Hornets Nest.
At the beginning of the day, Prentiss had 7,545 men present for duty. By the time he moved back to Barnes Field near the Hamburg-Purdy Road, after casualties and men that ran away, he had only 600 men and portions of two batteries. He deployed his men near the divisions of W.H.L. Wallace and Hurlbut, along the Sunken Road. Grant reinforced Prentiss with 600 men from the 23rd Missouri Infantry Regiment, which had disembarked from Pittsburg Landing a few hours earlier. Grant visited the 1,200-man force, and told Prentiss to "hold at all hazards".
The Union troops along the Sunken Road were protected by hickory and oak trees. Some Union troops at this location had modern (for 1862) weapons and fences for shelter, while some of the Confederate attacks were across open ground. These factors combined to make frontal assaults difficult for the Confederate attackers. One attack was led by Confederate division commander Benjamin F. Cheatham, and his Second Brigade was thoroughly repulsed. Southeast of the Sunken Road, Stuart still held the Union left. The Confederate brigades commanded by brigadier generals James R. Chalmers and John K. Jackson attacked Stuart's three regiments. The intensity of the fight increased around 11:15 am, causing most of the 71st Ohio Infantry Regiment to flee to the rear.[Note 12] Stuart repositioned his remaining two regiments, but eventually they began panicking. Although Stuart restored order, he was wounded and command temporarily fell to Lieutenant Colonel Oscar Malmborg.
By noon, Sherman and McClernand had been pushed back to Jones Field. However, the three regiments from McDowell's First Brigade had reunited with Sherman and McClernand, and three additional regiments arrived for reinforcement. McClernand's troops began a counterattack with the assistance of McDowell's brigade. The Confederates were pushed back beyond McClernand's morning headquarters, and both sides had numerous casualties. With reinforcements, the Confederate forces began a bayonet charge at about 1:00 pm that pushed McClernand and McDowell back to their original counterattack line at Jones Field.
On the Union right, the divisions of Sherman and McClernand (plus Veatch's brigade) were a disorganized group of individual soldiers and portions of regiments. Many soldiers had dropped their equipment and headed to Pittsburg Landing. Still, Sherman and McClernand fought on with the remnants of their divisions.
The situation at the Union center was much better. Prentiss repelled multiple attacks by the brigade commanded by Colonel Randall L. Gibson. Captain Andrew Hickenlooper's 5th Ohio Independent Light Artillery Battery used shrapnel and canister to stop the first charge, and Confederate losses were considerable. After a third try, Gibson's brigade suffered enough casualties (including one colonel hit in the face) that most of the men fell back, and the brigade was not engaged for the rest of the day. Among the Union soldiers killed was Major James Powell, who led the early morning patrol that discovered the Confederate army at Fraley Field. While Prentiss was defending against Gibson, Sweeny repelled Confederate attacks near Duncan Field.
The Union left, even more so than the right, was pushed back. Stuart's two remaining Union regiments, temporarily commanded by Lieutenant Colonel Malmborg in the absence of Colonel T. Kilby Smith, made several stands east of Bell Field against two of Bragg's brigades.[Note 13] Fortunately for the Union army, Bragg's hungry men exhausted their ammunition and pillaged food from the Union camps instead of continuing the attack. Around 2:15 pm, Smith ordered Stuart's brigade to withdraw, and by 2:30 pm Stuart's brigade was done fighting for the day.
While Stuart was fighting, the adjacent position in the Union line was occupied by McArthur's partial brigade. McArthur's force was attacked around 2:00 pm by one of Breckinridge's brigades. Despite reinforcements, McArthur fell back about 300 yards north of the Peach Orchard where he stabilized his line 20 minutes later. On McArthur's right, Hurlbut's division was also under attack, causing it to fall back. Most of the attackers were from Breckinridge's Third Brigade, commanded by Colonel Winfield S. Statham. As the Union troops fell back, they would pause to shoot at the oncoming Confederates. Artillery was also used to slow the attackers.
General Albert Sidney Johnston rode as much as 40 paces in front of Breckinridge's line. His uniform was torn from bullets in several places, and the heel of one of his boots was gone. After sending an order to Colonel Statham, an object could be heard striking Johnston. Although blood could be seen dripping from his leg, the general did not show concern. Shortly afterwards, he was slumping in his saddle. Asked if he was wounded, Johnston replied "Yes, and I fear seriously." Johnston bled to death from a torn popliteal artery in his right leg. Although a tourniquet might have saved Johnston's life, his personal physician had been sent elsewhere to treat the wounded. Johnston died about 100 yards (91 m) south of the Bell Farm at 2:30 pm.[Note 14] He was the highest-ranking soldier killed in combat in the American Civil War, and is still (2022) the highest ranking American military officer killed in any action.
With the death of Johnston, Beauregard officially became the Confederate army's commander. Some historians argue that since Beauregard was directing the army from the rear while Johnston was at the front, Beauregard already had the role of army commander. The Confederate attack on its right (Union left) stalled after Johnston's death, and many exhausted Confederate soldiers drank from what became known as the "Bloody Pond" located between the Peach Orchard and Wicker Field. The lull was caused more by the exhaustion and disorganized condition of the Confederate army than mourning for Johnston or Beauregard's lack of action. Beauregard sent Brigadier General Daniel Ruggles to coordinate an attack on the Hornet's Nest.
At 2:50 pm, Lieutenant William Gwin, commander of the USS Tyler, put his gunboat into action by firing on the Confederate batteries near the Union left. After an hour, Gwin was joined by the USS Lexington, and the two gunboats positioned themselves about three–fourths of a mile (1.21 km) south of Pittsburg Landing. At first, the shelling (gunboat shells were larger than those used by field artillery) had more of a psychological impact than a destructive one.
On the ground at the Union left, McArthur's partial brigade fought the Confederate brigades commanded by brigadier generals John K. Jackson and John S. Bowen. With Stuart now gone, McArthur was also getting outflanked by Chalmer's Brigade. Between 3:00 and 4:00 pm, McArthur moved all the way back to Pittsburg Landing.[Note 15] Hurlbut's line was also falling back, and only one regiment remained by 4:30 pm when Hurlbut ordered it to the rear.
Sometime in the late afternoon, Grant assigned Colonel Joseph Dana Webster, a veteran of the Mexican–American War, the task of setting up a defensive position at Pittsburg Landing. Webster used stragglers and noncombatant personnel. He began rounding up artillery pieces, including siege guns and any batteries (or partial batteries) that retreated back to the landing. He eventually assembled about 50 artillery pieces, and they were positioned on a ridge on the east side of the battlefield.[Note 16]
At the Union right, Grant visited Sherman around 3:00 pm, and found a difficult situation. The remaining regiments had few men, ammunition was low, and more men were either leaving or serving with other units. Some regiments had so many losses that they were ordered to Pittsburg Landing where they could reform. The Union line at this time was back to Jones Field and the surrounding area. The Confederate army facing Sherman and McClernand was reorganizing, and some of the units were shifted to the Hornet's Nest. After another attack at 4:00 pm, Sherman and McClernand fell back further around 5:00 pm.
On the Union left, Bragg tried to pursue the retreating Union soldiers, but was harassed by Union gunboats firing with increasing accuracy. The Tennessee River was near high tide, and the Union gunboat leaders had discovered that by elevating their guns and using lower charges, they could hit targets close to the river. The Tyler had some direct hits on Chalmer's Brigade beginning at 5:35 pm.
The Confederate army spent a considerable amount of time and resources assaulting the Hornet's Nest instead of bypassing it. Historians' estimates of the number of separate infantry charges, including those from earlier in the morning, range from eight to fourteen.[Note 17] An estimated 10,000 Confederate soldiers were involved. At 3:30 pm, the Confederate army began moving all available artillery pieces into positions around the Hornet's Nest. Soon they had, at the time, the largest concentration of field artillery (over 50 pieces) ever on the North American continent.[Note 18] This concentration, known as "Ruggles's Battery" was led by Brigadier General Ruggles. In his report, Ruggles claimed responsibility for assembling the batteries, but multiple people may have been involved—including Major Francis A. Shoup (Hardee's artillery chief) and Brigadier General James Trudeau. By 4:00 pm, the Confederate artillery was firing on Wallace and Prentiss in the Hornet's Nest. Confederate artillery was concentrated near Duncan Field and to the south near the Eastern Corinth Road. It was not until 4:30 pm that all Confederate artillery batteries were engaged, and at least one historian believes their effectiveness has been exaggerated.
Shortly after 4:00 pm, Hurlbut was gone from the east side of the Hornet's Nest, and McClernand had fallen back about a half mile (0.8 km) from the west side. Realizing that they were going to be surrounded, Brigadier General W.H.L. Wallace began leading his division north. Around 4:15 pm, he was mortally wounded as a portion of his division escaped encirclement. A ravine north of the Sunken Road near Cloud Field became known as "Hell's Hollow", and over 1,000 Union soldiers were captured there. By 4:45 pm, most of Wallace's division was removed from the battlefield, and Prentiss was left with about 2,000 men. Around 5:30 pm, various Union regiments began surrendering (including Prentiss), and approximately 2,200 Union soldiers were captured. In his memoirs, Grant was critical of Prentiss for not making a timely withdrawal. However, the Hornet's Nest stand by Prentiss and W.H.L. Wallace (who was there longer and had more men under his command) allowed Grant more time to prepare his Last Line.[Note 19]
By the time the Hornet's Nest fell, Grant's men had a defensive line from Pittsburg Landing to the Hamburg-Savannah Road and further north. Sherman commanded the right of the line, and McClernand took the center. On the left were the remnants of W.H.L. Wallace's division (commanded by Tuttle), plus Hurlbut's division. At the landing were 10,000 to 15,000 stragglers and noncombatants. The line included the artillery assembled by Colonel Webster, and the two gunboats were close by. Grant and Webster rode up and down the line, urging the men to keep firing at their enemy.
The advance of Buell's army, from Nelson's division, had begun arriving around 5:00 pm. Its 36th Indiana Infantry Regiment was placed on the east side of Grant's Last Line in time to help defend against an attack. The two navy gunboats helped defend, and the Lexington fired 32 rounds into the attacking Confederate force in only 10 minutes.[Note 20] The Confederate attack was repulsed, and shortly after 6:00 pm Beauregard called off all attacks. Buell and his army, and some in Grant's army, believed they had saved Grant's Army of the Tennessee. Grant had a differing opinion, believing that by 6:00 pm the Confederate army was worn out.
When Beauregard called off all attacks, it was near sunset and he assumed Grant's army could be eliminated on the next day. He had received a telegram saying Buell's army was in Alabama, and did not know Grant was already being reinforced.[Note 21] The Confederate army was badly disorganized, and it had just finished taking prisoners from the Hornet's Nest around 5:30 pm. Attacks after dark were rare because of problems with friendly fire, and darkness would occur soon. The exhausted Confederate army already had about 8,000 casualties.
For many years after the battle, critics believed Beauregard had squandered an opportunity to finish Grant's army. Modern historians, such as Cunningham and Daniel, disagree with that assessment. Cunningham wrote that Beauregard's critics ignore "the existing situation on the Shiloh battlefield"—including Confederate disorganization, time before sunset, and Grant's strong position augmented by gunboats. Daniel wrote that the thought that "the Confederates could have permanently breached or pulverized the Federal line in an additional hour or so of piecemeal night assaults simply lacks plausibility." He mentions that it took the Confederates six hours to conquer the Hornet's Nest, and Grant's Last Line was a stronger position. He also cites exhaustion, low ammunition, and one staff officer's belief that one third of the Confederate army was plundering instead of fighting.
Beauregard spent the evening near Shiloh Church in what had been Sherman's tent. Most of the Confederate army moved back to the original Union camps. Beauregard sent a telegram to Richmond discussing "a complete victory, driving the enemy from every position." Many of the Confederate troops believed that the battle was essentially over, and spent time plundering the camps. Some soldiers took their loot and began walking back to Corinth. Some of the Confederate troops were now armed with better weapons than the ones they had at the beginning of the day. Austrian, Enfield, and Springfield rifles were taken from dead, wounded, captured, or fleeing Union soldiers.
It began raining at 10:00 pm, and at midnight the rain became a storm with thunder and lightning. Because of the exhaustion and the belief that Grant's army was almost finished, the Confederate forces were not reorganized. No plans or orders were made for the next day, and it was thought the various commands would regroup at that time for a "final mop-up action". The original Confederate plan was to push Grant's army away from Pittsburg Landing, and pin it against the northern creeks where it could not move quickly or get resupplied. Instead, Grant had been forced back to a defensible position at Pittsburg Landing where he could be re-enforced and resupplied.
Grant's army had 7,000 men killed and wounded, 3,000 more captured, and 10,000 men who were afraid to fight. Before being reinforced, he had an estimated 18,000 fighters formed on his Last Line. Since most of the Union camps had been captured, these hungry and tired men would have to sleep in the open without blankets, and rain and cold weather added to their misery. At 7:15 pm, 5,800 fresh troops from Lew Wallace's division arrived at the battlefield and were positioned next to Sherman. Brigadier General Thomas Crittenden's division from Buell's army began arriving at 9:00 pm, and two hours later the entire division was at the landing. Eventually, Buell would have nearly 18,000 men available for the battle. The Union line from west to east consisted of the divisions commanded by Lew Wallace, Sherman, McClernand, Hurlbut, Crittenden, and Nelson. Prentiss' division was effectively destroyed, and Tuttle was behind the line trying to reorganize W.H.L. Wallace's division.
Earlier in the day, Colonel James B. McPherson, Grant's chief engineer, asked Grant if preparations should be started for a retreat. Grant's response was: "Retreat? No! I propose to attack at daylight and whip them." Buell met with Sherman at sunset, and learned that Grant planned to attack at sunrise. An understanding was made that Grant would have the west side of the line, while Buell would plan his own attack on the east side. Despite Grant's seniority, Buell considered himself independent, and Grant chose not to consult with him that evening. Sherman found Grant resting under a tree around midnight, and said: "Well, Grant, we've had the devil's own day, haven't we?" Grant replied: "Yes. Lick'em tomorrow, though."
Between midnight and 4:00 am, Brigadier General Alexander M. McCook's division from Buell's Army of the Ohio arrived in Savannah. The first unit from this division to arrive at Pittsburg Landing came ashore around 4:00 am. Elsewhere, the Confederate 47th Tennessee Infantry Regiment was marching to the battlefield. This poorly-armed regiment of 600 raw recruits was the only reinforcement Beauregard received, and it did not arrive until 8:00 am. After deducting casualties and those that had abandoned their posts, Beauregard's Confederate army now numbered less than 20,000 fighters.
On the east side of the Union line, Buell's attack began at 5:00 am with Nelson's three brigades. A few hours later, Nelson was joined on his right by Crittenden. The two divisions advanced, dispersed enemy skirmishers, and were gradually joined on Crittenden's right by brigades from McCook's division. McCook did not have all three of his brigades available until close to noon. On the Confederate side, Hardee commanded the right that faced Nelson, with the division commanded by Brigadier General Jones M. Withers as his most organized force. The skirmishers that Nelson had chased off earlier were Colonel Nathan Bedford Forrest's cavalry regiment and small portions of Chalmers's brigade from Withers' division. Behind the skirmishers were Chalmer's brigade and a makeshift brigade of three regiments. A mix of regiments formed the line further west, and several batteries gave artillery support.
At the Davis Wheat Field, a small field between Barnes Field and the Peach Orchard, the brigade commanded by Colonel William B. Hazen, took more than half of the losses Nelson's division received for the whole day. More fighting took place near Sara Bell Field, and after three hours of fighting it became stalemated. Both sides withdrew around noon, putting Nelson back at Wicker Field. During this fighting, Hardee was slightly wounded, although he led a counterattack. West of Nelson, Crittenden and McCook advanced before being forced back to Duncan field. At noon, Buell's army had control of the Hornet's Nest.
Grant's attack began with Lew Wallace's fresh division driving Pond's exhausted brigade away from Jones Field. After a Confederate counterattack by Gibson and Wood, Sherman brought his division to the line and the Confederates were pushed back. McClernand and Hurlbut joined the fight, and all four Union divisions advanced at 10:30 am. At that time, Cleburne's brigade of 800 men took significant casualties when they unsuccessfully assaulted the Union force.
Buell attacked again shortly after noon. In about two hours, Nelson and Crittenden reached the Hamburg-Purdy Road. Further west, McCook advanced westward on the Corinth-Pittsburg Landing Road, which caused a gap with Crittenden. The gap was filled by brigades from Grant's army that had been held in reserve. The Confederate army had held off Buell's fresh troops for a total of six hours, but their resistance was close to ending.
On Grant's side of the battlefield, Sherman and McClernand were stopped at noon when Cheatham's Confederate division attacked east of the crossroads and north of Water Oaks Pond. The two Union divisions were driven north about 300 yards (270 m). Despite light opposition at his front, Lew Wallace put his division in a defensive position, and did not resume the offensive until Sherman and McClernand had pushed back Cheatham's attackers. Bragg formed another line by Water Oaks Pond, and a two–hour fight ensued with Beauregard personally leading various Confederate units.
McCook's westward advance (instead of south), which began at 1:30 pm, meant that Bragg had Lew Wallace, Sherman, and McClernand on his front—and McCook on his right flank. After Bragg fell back south of the Hamburg-Purdy Road, Beauregard counterattacked using a force that was mostly Wood's brigade. Near Water Oaks Pond, this force pushed McCook back until McCook regrouped and repulsed the attackers. Soon Beauregard and Bragg were forced back, and Union troops crossed the Hamburg-Purdy Road at 2:30 pm.
All morning, Beauregard hoped that the arrival of 20,000 men under the command of Brigadier General Earl Van Dorn would change the battle momentum back to favoring the Confederates. He was eventually notified that Van Dorn was still far away, so preparations for a withdrawal to Corinth began about 1:00 pm.[Note 22] At about 2:00 pm, Breckenridge began forming his corps into a rear guard position near Shiloh Church. Confederate batteries around Shiloh Church began a bombardment campaign to deceive the Union soldiers into thinking the Confederate army was still present. Around 3:30 pm, the last of the Confederate artillery was hauled away toward Corinth.
Grant and Buell did not pursue the Confederate army, and have been criticized for their decisions. One historian called this the "final Federal Blunder", and believed that Lew Wallace's fresh division should have been sent in pursuit. It started to rain at 6:30 pm, and the rain turned to hail as the temperature dropped. The battle was over with a huge number of casualties on both sides.
At 10:00 am on April 8, Union forces commanded by Sherman and Wood began a pursuit of the Confederate forces. Breckinridge's covering force included about 350 cavalrymen commanded by Colonel Forrest. This group was a mixture of Forrest's men, John Hunt Morgan's Kentucky Cavalry, Texas Rangers, and the 1st Mississippi Cavalry (Adams' Cavalry). They were armed with revolvers and shotguns, and were instructed to fire only when they were within 20 steps of the enemy. On the left, two brigades from Wood's Union division skirmished with Wirt Adams's Cavalry Regiment and then returned to camp. On the right, a group led by Forrest attacked Sherman's men as they were clearing fallen timber near a small creek, causing some of them to run for their lives. Unofficial Union casualties were 15 killed, 25 wounded, and 53 taken prisoner. Among the few Confederate wounded was Forrest, who escaped after being shot at close range. Sherman ended the pursuit, and Breckinridge continued south.
Multiple sources list Union casualties as 13,047, with 1,754 killed, 8,408 wounded, and 2,885 missing or captured. Grant's army had 10,944 casualties, while Buell's had 2,103. Without counting those captured or missing, the brigades commanded by Sweeny, Veatch, and Colonel Nelson G. Williams all had over 600 killed or wounded. The report in the Official Records lists two brigade commanders as killed or mortally wounded, five wounded (including Sweeny), and one captured.[Note 23] One historian believes that the high number of officer losses caused casualty figures to be understated, and that they really total closer to 14,500.
Confederate casualties totaled to 10,699, with 1,728 killed, 8,012 wounded, and 959 missing or captured. Additional sources agree with those figures. The Confederate totals do not include reporting for cavalry or the 47th Tennessee Infantry Regiment that arrived for the second day of the battle. Similar to the understatement for Union casualties, one historian believes Confederate casualties were probably closer to 12,000. Using the commonly quoted statistics, Cleburne's brigade had 790 wounded and 188 killed, which was more killed and more wounded than any brigade in any of the armies at the battle. In addition to the wounding of Johnston (mortal) and Hardee (slight), Beauregard's report mentions six casualties for major generals and brigadier generals—one killed, three severely wounded, one slightly wounded, and one injured when his horse was shot. Another Confederate soldier killed was Samuel B. Todd, brother of President Abraham Lincoln's wife, Mary Todd Lincoln.
At the time, the battle was the largest fought in America. The high number of casualties helped convince many Union leaders that the war was not going to end quickly in the west. About 20,000 men were killed or wounded at Shiloh, while a similar count for earlier major battles at Manassas (a.k.a. Bull Run), Wilson's Creek, Fort Donelson, and Pea Ridge combines to only 12,000. Shiloh's total casualties of 23,746 (which may be understated) puts it in the top ten (6th or 7th) in the American Civil War.[Note 24]

Initially, news on the battle was positive for Grant. That changed a week later, especially when a "somewhat exaggerated" newspaper report was released. Whitelaw Reid was the article writer, although he used a pen name. The article said that Grant was surprised, and falsely claimed that Union soldiers were bayoneted in their tents. The article's only hero was Buell, who saved Grant. Self-serving accounts from some of Buell's officers also swayed public opinion, and rumors circulated that Grant was drunk.
Some of the more "savage denunciations" of Grant came from politicians representing Ohio and Iowa—home states of many of the men who ran away when fighting started. One politician complained to Lincoln, saying Grant was an incompetent drunk that was a political liability. Lincoln's response was "I can't spare this man; he fights." Sherman, who could have been one of the battle's scapegoats and did not get along with the press, received more praise than criticism. Halleck praised his performance and requested a promotion for him, noting that Sherman had "three horses killed under him" and was wounded twice. Halleck arrived at Pittsburg Landing on April 11 and took personal command—as he had planned earlier. On April 30, he named Grant as his second-in-command. This was a meaningless position, but Halleck's solution to the Grant criticism was a de facto suspension that satisfied the critics.
On April 8, Confederate president Jefferson Davis reported to the Confederate congress that according to the latest accounts, Johnston had gained a complete victory. A last-minute addition to his speech was mentioning Johnston's death. Before the battle, the public wanted Johnston removed because of the loss of most of Tennessee. Now he was a hero. Over the next few days, more information about the battle became available. The initial perception was that only "untoward events" had saved the Union army from destruction, and the withdrawal to Corinth was part of a strategic plan. Eventually, critics began to blame Beauregard for the defeat, citing the lack of a twilight attack on the first day of the battle.
The loss of Albert Sidney Johnston dealt a severe blow to Confederate morale, and President Davis believed that Johnston's death was the "turning point of our fate" in the Western Theater. With the loss at Shiloh, the likelihood of the Confederacy regaining control of the upper Mississippi Valley was severely diminished, and the large number of casualties represented the start of an unwinnable war of attrition. The victory at Shiloh also placed the Union army in a strategic position to infiltrate and capture key points in the south. Halleck led a reinforced Union army to Corinth, and the Confederates abandoned it on May 30. New Orleans, Baton Rouge, and Memphis were overrun by Union navy forces over the next three months. By July, Halleck was promoted to chief of staff in Washington, and Grant became commander of the now larger District of West Tennessee. Grant would lead a Siege of Vicksburg, causing nearly 30,000 Confederate troops to surrender on July 4, 1863.
The War Department established the Pittsburg Landing National Cemetery in 1866, and its name was changed to Shiloh National Cemetery in 1889. Shiloh National Military Park was established by the United States Congress on December 27, 1894. Originally under the administration of the War Department, the park was transferred to the National Park Service of the Department of the Interior in 1933. A private organization, the American Battlefield Trust, has been involved with saving more than 1,400 acres (570 ha) of the battlefield. Sites such as the Bloody Pond, Hornet's Nest, and Pittsburg Landing are part of the park. The Shiloh Church at the park is a nearly exact representation of the original, constructed using 150-year-old timber. Additional points in the park include Fraley Field, the Peach Orchard, Ruggles' Battery, Grant's Last Line, and the site of Johnston's death. In 2022, the park consisted of over 5,200 acres (2,100 ha).
