The '''Battle of Shiloh''', also known as the '''Battle of Pittsburg Landing''', was a major battle in the [[American Civil War]] fought on April 6–7, 1862. The fighting took place in southwestern [[Tennessee]], which was part of the war's [[Western Theater of the American Civil War|Western Theater]]. The battlefield is located between a small, undistinguished church named [[Shiloh, Hardin County, Tennessee|Shiloh]] and [[Pittsburg Landing, Tennessee|Pittsburg Landing]] on the [[Tennessee River]]. Two [[Union Army|Union]] armies combined to defeat the [[Confederate States Army|Confederate]] [[Army of Mississippi]]. [[Major general (United States)|Major General]] [[Ulysses S. Grant]] was the Union commander, while [[General officers in the Confederate States Army#General|General]] [[Albert Sidney Johnston]] was the Confederate commander until his battlefield death, when he was replaced by his second-in-command, General [[P. G. T. Beauregard]].

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 on 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 was also joined by portions of the [[Army of the Ohio]], under the command of 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 army withdrew further south, and a modest Union pursuit started and ended on the next day.

Though victorious, the Union army had around 2,500 more casualties than the Confederates. After the surprise and lengthy Union casualty list became known, Grant was heavily criticized; in fact, decisions made by both the Federal and Confederate high command were afterward questioned by individuals on and off the battlefield. 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 of the entire war.

During February 1862, a [[Union (American Civil War)|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]].<ref name="Shaara5">{{harvnb|Shaara|2006|p=5}}</ref> 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 [[Confederate States of America|Confederacy]] as transportation routes, and also connected the city of [[Nashville, Tennessee|Nashville]], an [[ironworks]], and major agricultural areas. Nashville was a converging point for railroads, a major producer of [[gunpowder]], and a major supply depot.<ref name="McPherson393">{{harvnb|McPherson|1988|p=393}}</ref> The Union army increased its firepower in those battles by receiving assistance from [[Union Navy|U.S. Navy]] [[USS Lexington (1861)|gunboats]].<ref name="McPherson392">{{harvnb|McPherson|1988|p=392}}</ref> The steam-powered gunboats were flat-bottomed, armored, and carried up to 13 [[artillery]] pieces.<ref name="McPherson393"/> Grant was rewarded for his success by a promotion to [[Major general (United States)|major general]], making him senior to all generals in the [[Western Theater of the American Civil War|Western Theater]] (between the [[Appalachian Mountains]] and [[Mississippi River]]) with the exception of Major General [[Henry Halleck]].<ref name="Chernow186">{{harvnb|Chernow|2017|p=186}}</ref>

Continuing their push into Confederate territory, Union troops arrived at the Tennessee River town of [[Savannah, Tennessee]], on March 11.<ref name="Daniel71">{{harvnb|Daniel|1997|p=71}}</ref> By mid-March, a large number of Union troops were camped there and at [[Landing (water transport)|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.<ref name="Chernow195">{{harvnb|Chernow|2017|p=195}}</ref> Union leadership realized that its troops were too spread out, so it was decided to concentrate troops at [[Pittsburg Landing, Tennessee|Pittsburg Landing]].<ref name="Daniel104-105">{{harvnb|Daniel|1997|pp=104–105}}</ref> Pittsburg Landing is {{convert|9|mi|km|spell=in}} upriver (south) of Savannah, and it had a road that led to [[Corinth, Mississippi]].<ref name="Daniel70">{{harvnb|Daniel|1997|p=70}}</ref> About {{convert|3|mi|km|spell=in}} inland from the landing was a log church named Shiloh (a [[Hebrew language|Hebrew]] word meaning "place of peace"), and it is from this church that the battle gets its name.<ref name="Daniel70"/><ref name="Eicher222">{{harvnb|Eicher|2001|p=222}}</ref> The battle has also been called the ''Battle of Pittsburg Landing''.<ref name="Scott93">{{harvnb|Scott|1884|p=93}}</ref>{{#tag:ref|The Confederacy named the battle after the small church named Shiloh that was located near the position of the initial attack.

The Confederate Army's February 6 loss at Fort Henry caused it to abandon Kentucky and parts of Tennessee.<ref name="Cunningham54">{{harvnb|Cunningham|2009|p=54}}</ref> The last Confederate troops in Nashville moved south on February 23.<ref name="McPherson402">{{harvnb|McPherson|1988|p=402}}</ref> General [[Albert Sidney Johnston]], Confederate commander of the Western Theater, made the controversial decision to abandon the region. 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.<ref name="Shaara6">{{harvnb|Shaara|2006|p=6}}</ref> Confederate leadership decided to consolidate forces in Corinth, Mississippi, which is just south of the Tennessee–Mississippi border.<ref name="Eicher219">{{harvnb|Eicher|2001|p=219}}</ref> The town of Corinth had 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.<ref name="Shaara6"/><ref name="Daniel68">{{harvnb|Daniel|1997|p=68}}</ref> By the end of March, over 40,000 Confederate troops were concentrated at Corinth.<ref name="Eicher219"/>

===Union and Confederate plans===
[[Image:Union Camps at Shiloh.png|thumb|upright=1.5|right|Union camps at Shiloh|alt=map showing Union camps between Shiloh Church and Pittsburg Landing on the Tennessee River, with camps of Sherman and Prentiss being closest to Corinth]]
The Union plan was to combine Grant's and Buell's armies and continue its southward offensive.<ref name="McPherson406">{{harvnb|McPherson|1988|p=406}}</ref> If the combined armies could move south and capture Corinth, they would have a good starting point for the capture of [[Memphis, Tennessee|Memphis]], [[Vicksburg, Mississippi|Vicksburg]], and large portions of Confederate territory.<ref name="Chernow195"/> While most of Grant's army camped near the river at Pittsburg Landing in early April, one division was {{convert|5|mi|km|spell=in}} downstream (north) at Crump's Landing, and army headquarters remained further north in Savannah.<ref name="Eicher222"/> 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.<ref name="Shaara6"/>{{#tag:ref|The Union army move from Nashville to Savannah was delayed by the slow construction of a bridge across the [[Duck River (Tennessee)|Duck River]] at [[Columbia, Tennessee|Columbia]].

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.<ref name="McPherson406"/>{{#tag:ref|A small Confederate army of 15,000 men, led by Major General [[Earl Van Dorn]], was ordered to Corinth—but did not arrive in time for the Battle of Shiloh.<ref name="McPherson405">{{harvnb|McPherson|1988|p=405}}</ref>|group=Note}} 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{{nbsp}}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.<ref name="McPherson406-407">{{harvnb|McPherson|1988|pp=406–407}}</ref> 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 Creek (Tennessee River tributary)|Snake]] and Owl creeks. Confederate troops along the Tennessee River would prevent Union reinforcements and resupply.<ref name="Eicher224"/>

The Confederate army at the Battle of Shiloh was the [[Army of Mississippi]], commanded by [[General officers in the Confederate States Army#General|General]] Albert Sidney Johnston, with General [[P.

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 (brigadier general)|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.

Around 5:30{{nbsp}}am, Confederate leaders heard the commotion at Fraley Field, and Johnston ordered a general attack.<ref name="Daniel144"/> 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.<ref name="Eicher226">{{harvnb|Eicher|2001|p=226}}</ref>{{#tag:ref|Johnston was under tremendous pressure to perform well after the losses in Tennessee.<ref name="McPherson405"/> He felt that he could make his army more effective by inspiring his inexperienced troops in person.<ref name="Esposito34">{{harvnb|Esposito|1959|p=34}}</ref>|group=Note}} On the Union side, Powell sent a message to Colonel Peabody that he was being driven back by an enemy force of several thousand.<ref name="Daniel145">{{harvnb|Daniel|1997|p=145}}</ref> 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.<ref name="Daniel147">{{harvnb|Daniel|1997|p=147}}</ref> 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.<ref name="Cunningham154">{{harvnb|Cunningham|2009|p=154}}</ref> Although Peabody's patrol had alerted the Union army, some Union leaders were not convinced that they were under attack.

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.<ref name="Daniel149">{{harvnb|Daniel|1997|p=149}}</ref> 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 {{convert|3|mi|km}} wide.<ref name="Cunningham200">{{harvnb|Cunningham|2009|p=200}}</ref> At about 7:30{{nbsp}}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.<ref name="Esposito34"/> 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.<ref name="Cunningham200"/> The attack went forward as a [[frontal assault]].<ref name="Eicher224-226">{{harvnb|Eicher|2001|pp=224–226}}</ref> 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.<ref name="Daniel119">{{harvnb|Daniel|1997|p=119}}</ref>

===Sherman and Prentiss===
[[File:BattleOfShilohDay1West9AM.png|thumb|upright=1.5|The divisions of Sherman and Prentiss were the first Union troops attacked|alt=Map showing Fraley Field, Shiloh Church, Crossroads, and troop positions]]
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.<ref name="McPherson408"/> Sherman, who had been negligent in preparing for an attack, performed with "coolness and courage" while he inspired his raw troops.<ref name="McPherson409">{{harvnb|McPherson|1988|p=409}}</ref>{{#tag:ref|Historian [[James M. McPherson]] cites the first day of the battle as the turning point of Sherman's life, helping him to become one of the premier Union generals.<ref name="McPherson409"/>|group=Note}} Facing artillery fire and a frontal attack from the corps of Hardee, Bragg, and Polk, Sherman's men performed reasonably well—if they fought.<ref name="Eicher226"/> The inexperienced colonel of the [[53rd Ohio Infantry Regiment]], which had just repelled two Confederate advances, yelled "retreat and save yourselves", and many from his regiment ran away.<ref name="Cunningham169">{{harvnb|Cunningham|2009|p=169}}</ref> Eventually, at least two companies of the calmer men from this regiment attached to another regiment.<ref name="Cunningham169-171">{{harvnb|Cunningham|2009|pp=169–171}}</ref> Sherman slowly moved the division back to a position behind Shiloh Church.<ref name="Eicher226"/> He became supported on his left by the Third Brigade from McClernand's division.<ref name="Cunningham174">{{harvnb|Cunningham|2009|p=174}}</ref>

Prentiss had his camps northeast of Seay Field.<ref name="Cunningham193">{{harvnb|Cunningham|2009|p=193}}</ref> On his right, his brigade commanded by Peabody was attacked by two Confederate brigades, and Peabody was wounded four times before being killed.<ref name="Daniel151">{{harvnb|Daniel|1997|p=151}}</ref> By 8:30{{nbsp}}am, the remnants of Peabody's brigade were pushed north, and the Confederate army occupied his camp.<ref name="Daniel152">{{harvnb|Daniel|1997|p=152}}</ref> Further east, Prentiss's other brigade was attacked by brigades commanded by Brigadier General [[Adley H.

Looting became a problem, as Confederate soldiers found clothing, rifles, and food. Confederate leaders found it difficult to control their forces.<ref name="Cunningham199-200">{{harvnb|Cunningham|2009|pp=199–200}}</ref> They paused their attack, which enabled Prentiss to move further north.<ref name="Daniel156">{{harvnb|Daniel|1997|p=156}}</ref>

East of McClernand, Hurlbut had all three brigades ready for action at 8:00{{nbsp}}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.<ref name="Cunningham201">{{harvnb|Cunningham|2009|p=201}}</ref> Shortly after that first message, Hurlbut was advised that Prentiss was in trouble. Hurlbut brought his remaining two brigades south on the Hamburg-Savannah 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.<ref name="Cunningham202">{{harvnb|Cunningham|2009|p=202}}</ref>

===Pittsburg Landing and the Union left===
[[File:BattleOfShilohDay1East9AM.png|thumb|upright=1.5|At 9:00 am, Stuart could hear artillery fire, but was not yet attacked|alt=Map showing Sunken Road, Peach Orchard, Pittsburg Landing, Tennessee River, and troop positions]]
Grant was in Savannah having breakfast at his [[Cherry Mansion]] headquarters when he heard the distant sounds of artillery fire.<ref name="Chernow200">{{harvnb|Chernow|2017|p=200}}</ref> 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.<ref name="Daniel139">{{harvnb|Daniel|1997|p=139}}</ref>{{#tag:ref|Ahead of most of his divisions, Buell had already arrived in Savannah, and was walking to Grant's headquarters when Grant departed by boat for Pittsburg Landing.<ref name="Cunningham158">{{harvnb|Cunningham|2009|p=158}}</ref>|group=Note}} 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.<ref name="Daniel242">{{harvnb|Daniel|1997|p=242}}</ref> Grant then took his steamboat, ''Tigress'', south to Crump's Landing, where he told Lew Wallace to get his division ready to move.<ref name="Daniel174">{{harvnb|Daniel|1997|p=174}}</ref> Grant proceeded to Pittsburg Landing, arriving around 9:00{{nbsp}}am.<ref name="Daniel175">{{harvnb|Daniel|1997|p=175}}</ref>{{#tag:ref|Sources have slight differences for Grant's Pittsburg Landing arrival time.

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.<ref name="Cunningham159-160">{{harvnb|Cunningham|2009|pp=159–160}}</ref>{{#tag:ref|This order would be the subject of controversy, as Lew Wallace disputed where he was told to go and by what route, and claimed the copy of the order was lost.<ref name="Cunningham160">{{harvnb|Cunningham|2009|p=160}}</ref>|group=Note}}

After the beginning of the battle, Brigadier General W.H.L. Wallace sent his Second Brigade, commanded by Brigadier General [[John McArthur (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.<ref name="Cunningham238">{{harvnb|Cunningham|2009|p=238}}</ref> 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", 1st Illinois Light Artillery Regiment|Battery A from the 1st Illinois Light Artillery Regiment]]. Wallace's First and Third brigades, commanded by Colonel [[James M. Tuttle]] and Colonel [[Thomas William Sweeny|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.<ref name="Cunningham238-240">{{harvnb|Cunningham|2009|pp=238–240}}</ref> From 9:30{{nbsp}}am to 10:30{{nbsp}}am, most of the fighting at this position was the exchange of artillery fire.<ref name="Cunningham242-243">{{harvnb|Cunningham|2009|pp=242–243}}</ref>

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.<ref name="Daniel198">{{harvnb|Daniel|1997|p=198}}</ref> At 9:30{{nbsp}}am Johnston received reports that Union soldiers were deploying on the Confederate right [[Flanking maneuver|flank]]. To remedy this potential problem, he sent two brigades from Bragg's Corps, and called up Breckinridge'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.<ref name="Daniel196-197">{{harvnb|Daniel|1997|pp=196–197}}</ref> Around 9:40{{nbsp}}am Stuart began receiving artillery fire, and twenty minutes later his men were attacked by Confederate infantry.<ref name="Daniel199">{{harvnb|Daniel|1997|p=199}}</ref>

===Crossroads===
[[File:Shiloh battlefield topical map V2.png|thumb|upright=1.5|Topographical map of Shiloh Battlefield|alt=topographical map of battlefield including Fraley Field, Shiloh Church, Crossroads, Hornet's Next, and Pittsburg Landing]]
Shortly after 10:00{{nbsp}}am, the remnants of Sherman's division established a new position further north from Shiloh Church.<ref name="Cunningham219">{{harvnb|Cunningham|2009|p=219}}</ref> This position was near a crossroads of the Hamburg–Purdy Road with the Pittsburg–Corinth Road.<ref name="Daniel183">{{harvnb|Daniel|1997|p=183}}</ref> 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.<ref name="Cunningham219"/> Sherman's First Brigade, commanded by Colonel [[John Adair McDowell (colonel)|John A. McDowell]] was west on the Hamburg–Purdy Road and cut off.<ref name="Cunningham222">{{harvnb|Cunningham|2009|p=222}}</ref> Colonel [[Ralph Pomeroy Buckland|Ralph P. Buckland]]'s Fourth Brigade was fragmented and ammunition was low.<ref name="Cunningham221">{{harvnb|Cunningham|2009|p=221}}</ref>

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.<ref name="Cunningham222"/> Sherman also had the [[6th Independent Battery Indiana Light Artillery|6th Indiana Artillery Battery]] commanded by [[Captain (United States O-3)|Captain]] Frederick Behr, and part of a [[Battery "E", 2nd Illinois Light Artillery Regiment|battery]] from McClernand.<ref name="Daniel183"/> 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.<ref name="Cunningham222"/>

After a failed attack and the addition of more men, the Confederates attacked Sherman and McClernand again at 11:00{{nbsp}}am.<ref name="Daniel183"/> This Confederate attacking force consisted of portions of seven brigades.<!--AnClSmStRuWoSh--><ref name="Cunningham225">{{harvnb|Cunningham|2009|p=225}}</ref> 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.<ref name="Daniel183-184">{{harvnb|Daniel|1997|pp=183–184}}</ref> On the Confederate side, Wood's brigade took heavy losses, but routed the brigade of Colonel [[C. Carroll Marsh]] from McClernand's division.<ref name="Cunningham229-230">{{harvnb|Cunningham|2009|pp=229–230}}</ref> 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.<ref name="Cunningham233">{{harvnb|Cunningham|2009|p=233}}</ref> By 11:20{{nbsp}}am, the Confederate army controlled the Hamburg-Purdy Road.<ref name="Cunningham236">{{harvnb|Cunningham|2009|p=236}}</ref> Benefitting from the exhaustion and disorganization of the Confederate force, Sherman and McClernand fell back about {{convert|200|yd}} north of the crossroads.<ref name="Cunningham236"/> Sherman's separated First Brigade (McDowell) linked with McClernand around 11:30{{nbsp}}am.<ref name="Cunningham222"/>

===Sunken Road and Hornet's Nest===
[[File:BattleOfShilohGrantSituation.png|thumb|upright=1.5|Grant's right and left were pushed back|alt=Grant's situation at noon: right and left pushed back, center holding, Lew Wallace's division absent, Buell's army miles north]]
The Sunken Road was an old wagon track called "an abandoned road" in the only time it was mentioned in the [[Official Records of the Union and Confederate Armies|''Official Records'']]. From west to east, it ran from Duncan Field to a peach orchard (eventually known as "the Peach Orchard") at the Hamburg-Savannah Road.<ref name="Cunningham240">{{harvnb|Cunningham|2009|p=240}}</ref> The old wagon track was so worn and washed–over that it had an embankment that ranged from a few inches (7.6&nbsp;cm) to supposedly {{convert|3|ft|m|spell=in}}. This ready-made entrenchment received the name "Sunken Road" in post-war years.<ref name="Daniel203">{{harvnb|Daniel|1997|p=203}}</ref> 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 in a regiment that was not close enough to the road to see it.<ref name="Cunningham241n">{{harvnb|Cunningham|2009|p=241n}}</ref> 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.<ref name="Cunningham241">{{harvnb|Cunningham|2009|p=241}}</ref>

At the beginning of the day, Prentiss had 7,545 men present for duty.<ref name="Daniel322"/> 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.<ref name="Daniel202-203">{{harvnb|Daniel|1997|pp=202–203}}</ref> 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".<ref name="Daniel202-203"/>

The Union troops along the Sunken Road were protected by hickory and oak trees.<ref name="Cunningham241"/> 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.<ref name="Gudmens26">{{harvnb|Gudmens|Combat Studies Institute (U.S.), Staff Ride Team|2005|p=26}}</ref> One attack was led by Confederate division commander [[Benjamin F. Cheatham]], and his Second Brigade was thoroughly repelled.<ref name="Cunningham246">{{harvnb|Cunningham|2009|p=246}}</ref> 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{{nbsp}}am, causing most of the [[71st Ohio Infantry Regiment]] to flee to the rear.<ref name="Cunningham211">{{harvnb|Cunningham|2009|p=211}}</ref>{{#tag:ref|Colonel Rodney Mason, commander of the 71st Ohio, fled to the rear, and many of his men followed him.

==Battle, afternoon of April 6==
[[File:BattleOfShilohDay1noon.png|thumb|upright=1.5|By noon, the Union right was pushed back and the left was threatened|alt=map showing noon positions, with Union right pushed back from Crossroads, center along Sunken Road, and left still in place]]
Lew Wallace's division had made little progress following Grant's order to move to the battlefield. Early in the morning, his division had been spread as much as {{convert|5|mi|km|spell=in}} from Crump's Landing. The purpose of this positioning was to protect routes that would be used by reinforcements in case ''his'' isolated division was attacked.<ref name="Daniel256">{{harvnb|Daniel|1997|p=256}}</ref> An additional messenger from Grant found him at 11:30{{nbsp}}am, and Wallace did not get his division moving until noon.<ref name="Daniel258">{{harvnb|Daniel|1997|p=258}}</ref> Another messenger found Wallace at 2:00{{nbsp}}pm, and notified Wallace that he was on the wrong road. Wallace believed he was to reinforce Sherman and McClernand at their original camps—he was unaware that those divisions had been pushed back toward Pittsburg Landing.<ref name="Daniel259">{{harvnb|Daniel|1997|p=259}}</ref>

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.<ref name="Cunningham247">{{harvnb|Cunningham|2009|p=247}}</ref> McClernand's troops began a counterattack with the assistance of McDowell's brigade.<ref name="Cunningham249">{{harvnb|Cunningham|2009|p=249}}</ref> 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{{nbsp}}pm that pushed McClernand and McDowell back to their original counterattack line at Jones Field.<ref name="Cunningham253-254">{{harvnb|Cunningham|2009|pp=253–254}}</ref>

===Early afternoon===
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.<ref name="Cunningham254-256">{{harvnb|Cunningham|2009|pp=254–256}}</ref>

The situation at the Union center was much better. Prentiss repelled multiple attacks by the brigade commanded by Colonel [[Randall L. Gibson]].<ref name="Cunningham256-261">{{harvnb|Cunningham|2009|pp=256–261}}</ref> Captain [[Andrew Hickenlooper]]'s [[5th Ohio Independent Light Artillery Battery]] used shrapnel and canister to stop the first charge, and Confederate losses were considerable.<ref name="Cunningham256-257">{{harvnb|Cunningham|2009|pp=256–257}}</ref> 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.<ref name="Cunningham259-261">{{harvnb|Cunningham|2009|pp=259–261}}</ref> Among the Union soldiers killed was Major James Powell, who led the early morning patrol that discovered the Confederate army at Fraley Field.<ref name="Cunningham259">{{harvnb|Cunningham|2009|p=259}}</ref> While Prentiss was defending against Gibson,  Sweeny repelled Confederate attacks near Duncan Field.<ref name="Cunningham261">{{harvnb|Cunningham|2009|p=261}}</ref>

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 [[Thomas Kilby Smith|T. Kilby Smith]], made several stands east of Bell Field against two of Bragg's brigades.<ref name="Daniel200">{{harvnb|Daniel|1997|p=200}}</ref>{{#tag:ref|After being wounded, Stuart turned command over to Colonel T.

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{{nbsp}}pm by one of Breckinridge's brigades.<ref name="Daniel222-223">{{harvnb|Daniel|1997|pp=222–223}}</ref> Despite reinforcements, McArthur fell back about 300 yards north of the Peach Orchard where he stabilized his line 20 minutes later.<ref name="Daniel224">{{harvnb|Daniel|1997|p=224}}</ref> On McArthur's right, Hurlbut's division was also under attack, causing it to fall back.

====Johnston killed====
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.<ref name="Daniel226">{{harvnb|Daniel|1997|p=226}}</ref> After sending an order to Colonel Statham, an object could be heard striking Johnston.

With the death of Johnston, Beauregard officially became the Confederate army's commander.<ref name="Cunningham277">{{harvnb|Cunningham|2009|p=277}}</ref> 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.<ref name="Daniel145"/><ref name="Esposito34"/> 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.<ref name="Daniel234-235">{{harvnb|Daniel|1997|pp=234–235}}</ref> 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.<ref name="Cunningham277-278">{{harvnb|Cunningham|2009|pp=277–278}}</ref>

====Union left and right====
[[File:Lexington and Tyler at Shiloh.jpg|thumb|upright=1.00|right|Union gunboats joined the battle|alt=drawing of two steam-powered gunboats with big paddle-wheels on river]]
At 2:50{{nbsp}}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&nbsp;km) south of Pittsburg Landing. At first, the shelling (gunboat shells were larger than those used by [[Field artillery in the American Civil War|field artillery]]) had more of a psychological impact than a destructive one.<ref name="Cunningham312-313">{{harvnb|Cunningham|2009|pp=312–313}}</ref>

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 Chalmers's Brigade.<ref name="Cunningham293-295">{{harvnb|Cunningham|2009|pp=293–295}}</ref> Between 3:00 and 4:00{{nbsp}}pm, McArthur moved all the way back to Pittsburg Landing.{{#tag:ref|Daniel's map shows Hurlbut and McArthur moving to the rear at 4:00{{nbsp}}pm.<ref name="Daniel220">{{harvnb|Daniel|1997|p=220}}</ref> Esposito has McArthur falling back at 3:00{{nbsp}}pm.<ref name="Esposito36">{{harvnb|Esposito|1959|p=36}}</ref>|group=Note}} Hurlbut's line was also falling back, and only one regiment remained by 4:30{{nbsp}}pm when Hurlbut ordered it to the rear.<ref name="Daniel225">{{harvnb|Daniel|1997|p=225}}</ref>

===Late afternoon===
[[File:BattleOfShilohGrantsLastLine.png|thumb|upright=1.0|Webster organized Grant's Last Line|alt=Grant's Last Line near Pittsburg Landing on the Tennessee River, with 50+ artillery pieces and the two gunboats nearby]]
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 artillery in the American Civil War|siege guns]] and any batteries (or partial batteries) that retreated back to the landing.<ref name="Daniel246">{{harvnb|Daniel|1997|p=246}}</ref><ref name="Cunningham305">{{harvnb|Cunningham|2009|p=305}}</ref> He eventually assembled about 50 artillery pieces, and they were positioned on a ridge on the east side of the battlefield.<ref name="Esposito37">{{harvnb|Esposito|1959|p=37}}</ref>{{#tag:ref|Sources differ on the number of guns (artillery pieces) positioned at Grant's Last Line, and this is discussed in a long footnote in Cunningham's book.<ref name="Cunningham307n">{{harvnb|Cunningham|2009|p=307n}}</ref> Daniel says 41.<ref name="Daniel246"/> Esposito says 50.<ref name="Esposito37"/> Eicher says "more than fifty".<ref name="Eicher228">{{harvnb|Eicher|2001|p=228}}</ref> Gudmens says 52.<ref name="Gudmens113">{{harvnb|Gudmens|Combat Studies Institute (U.S.), Staff Ride Team|2005|p=113}}</ref>|group=Note}}

At the Union right, Grant visited Sherman around 3:00{{nbsp}}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.<ref name="Cunningham278">{{harvnb|Cunningham|2009|p=278}}</ref> The Union line at this time was back to Jones Field and the surrounding area.<ref name="Cunningham279">{{harvnb|Cunningham|2009|p=279}}</ref> The Confederate army facing Sherman and McClernand was reorganizing, and some of the units were shifted to the Hornet's Nest.<ref name="Cunningham278"/> After another attack at 4:00{{nbsp}}pm, Sherman and McClernand fell back further around 5:00{{nbsp}}pm.<ref name="Cunningham286">{{harvnb|Cunningham|2009|p=286}}</ref>

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 Chalmers's Brigade beginning at 5:35{{nbsp}}pm.<ref name="Cunningham313">{{harvnb|Cunningham|2009|p=313}}</ref>

====Hornet's Nest becomes focus====

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.<ref name="Daniel214">{{harvnb|Daniel|1997|p=214}}</ref>{{#tag:ref|McPherson mentions "a dozen separate assaults".<ref name="McPherson410">{{harvnb|McPherson|1988|p=410}}</ref> Daniel criticizes "modern historians" who condemn Bragg for ordering 11 to 14 assaults, since Daniel accounts for only eight—including some not ordered by Bragg. He also believes flanking attacks on the Hornet's Nest should have been made earlier.<ref name="Daniel214"/>|group=Note}} An estimated 10,000 Confederate soldiers were involved.<ref name="Daniel214"/> At 3:30{{nbsp}}pm, the Confederate army began moving all available artillery pieces into positions around the Hornet's Nest.<ref name="Daniel228">{{harvnb|Daniel|1997|p=228}}</ref> Soon they had, at the time, the largest concentration of field artillery (over 50 pieces) ever on the [[North America]]n continent.<ref name="Daniel228-229">{{harvnb|Daniel|1997|pp=228–229}}</ref>{{#tag:ref|Historians do not agree on the number of artillery pieces in place.

Shoup]] (Hardee's artillery chief) and Brigadier General James Trudeau.<ref name="Scott472">{{harvnb|Scott|1884|p=472}}</ref><ref name="Daniel229"/> By 4:00{{nbsp}}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.<ref name="Daniel229"/> It was not until 4:30{{nbsp}}pm that all Confederate artillery batteries were engaged, and at least one historian believes their effectiveness has been exaggerated.<ref name="Daniel230">{{harvnb|Daniel|1997|p=230}}</ref>

Shortly after 4:00{{nbsp}}pm, Hurlbut was gone from the east side of the Hornet's Nest, and McClernand had fallen back about a half mile (0.8&nbsp;km) from the west side.<ref name="Daniel231">{{harvnb|Daniel|1997|p=231}}</ref> Realizing that they were going to be surrounded, Brigadier General W.H.L.

However, the Hornet's Nest stand by Prentiss and W.H.L.

===Evening===
[[File:BattleOfShilohEndOfFirstDay.png|thumb|upright=1.5|Positions at the end of the first day|alt=map showing Grant's Last Line at the end of the day with Confederate forces nearby. Line extends from Pittsburg Landing west to Hamburg-Savannah Road, where it turns north (right)]]
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.<ref name="Cunningham308">{{harvnb|Cunningham|2009|p=308}}</ref> 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.<ref name="Daniel245"/> At the landing were 10,000 to 15,000 stragglers and noncombatants.<ref name="Cunningham321n">{{harvnb|Cunningham|2009|p=321n}}</ref> The line included the artillery assembled by Colonel Webster, and the two gunboats were close by.<ref name="Cunningham308"/> Grant and Webster rode up and down the line, urging the men to keep firing at their enemy.<ref name="Cunningham322">{{harvnb|Cunningham|2009|p=322}}</ref>

The advance of Buell's army, from Nelson's division, had begun arriving around 5:00{{nbsp}}pm.<ref name="Daniel246"/> Its [[36th Indiana Infantry Regiment]] was placed on the east side of Grant's Last Line in time to help defend against an attack.<ref name="Cunningham323">{{harvnb|Cunningham|2009|p=323}}</ref> The two navy gunboats helped defend, and the ''Lexington'' fired 32 rounds into the attacking Confederate force in only 10{{nbsp}}minutes.<ref name="Cunningham323"/>{{#tag:ref|Opinions vary on the effectiveness of the gunboats.<ref name="Gudmens114">{{harvnb|Gudmens|Combat Studies Institute (U.S.), Staff Ride Team|2005|p=114}}</ref> Corps commander Bragg reported that the gunboat fire "though terrific in sound and producing some consternation at first, did us no damage...."<ref name="Scott466">{{harvnb|Scott|1884|p=466}}</ref> Yet Confederate regimental commander Lieutenant Colonel [[Calvin D.

Grant had a differing opinion, believing that by 6:00{{nbsp}}pm the Confederate army was worn out.<ref name="Daniel249">{{harvnb|Daniel|1997|p=249}}</ref>

====Beauregard's situation====
When Beauregard called off all attacks, it was near sunset and he assumed Grant's army could be eliminated on the next day.<ref name="Cunningham323-324">{{harvnb|Cunningham|2009|pp=323–324}}</ref> He had received a telegram saying Buell's army was in [[Alabama in the American Civil War|Alabama]], and did not know Grant was already being reinforced.<ref name="Gudmens114"/>{{#tag:ref|One of Buell's divisions was in Alabama, but not his entire army.<ref name="Gudmens114"/> Late in the evening, a squad of Colonel [[Nathan Bedford Forrest]]'s men discovered Union reinforcements arriving at Pittsburg Landing, and this was reported to Hardee. However, the rain and darkness prevented the men from finding Beauregard, and he was not notified.<ref name="Daniel263-264">{{harvnb|Daniel|1997|pp=263–264}}</ref>|group=Note}} The Confederate army was badly disorganized, and it had just finished taking prisoners from the Hornet's Nest around 5:30{{nbsp}}pm. Attacks after dark were rare because of problems with friendly fire, and darkness would occur soon.<ref name="Cunningham324-325">{{harvnb|Cunningham|2009|pp=324–325}}</ref> The exhausted Confederate army already had about 8,000 casualties.<ref name="Daniel263">{{harvnb|Daniel|1997|p=263}}</ref>

[[File:BattleOfShilohBeauregard.png|thumb|upright=1.5|Confederate situation appeared better than it was|alt=Beauregard's Situation at sunset: attack halted, battlefield success, and plans to finish tomorrow]]For many years after the battle, critics believed Beauregard had squandered an opportunity to finish Grant's army.<ref name="Cunningham324">{{harvnb|Cunningham|2009|p=324}}</ref> 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.<ref name="Cunningham324-325"/> 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."<ref name="Daniel256"/> 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.<ref name="Daniel256"/>

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.<ref name="Daniel262">{{harvnb|Daniel|1997|p=262}}</ref> Beauregard sent a telegram to Richmond discussing "a complete victory, driving the enemy from every position."<ref name="McPherson412">{{harvnb|McPherson|1988|p=412}}</ref><ref name="Scott384">{{harvnb|Scott|1884|p=384}}</ref> 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.<ref name="Daniel262-263">{{harvnb|Daniel|1997|pp=262–263}}</ref> 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.<ref name="Cunningham337">{{harvnb|Cunningham|2009|p=337}}</ref>

It began raining at 10:00{{nbsp}}pm, and at midnight the rain became a storm with thunder and lightning.  This, combined with the constant shelling by Union gunboats throughout the night, made it difficult for the exhausted Confederates to get any sleep. 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".<ref name="Daniel262-263"/> 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.<ref name="Eicher224"/> Instead, Grant had been forced back to a defensible position at Pittsburg Landing where he could be reinforced and resupplied.<ref name="Shaara11">{{harvnb|Shaara|2006|p=11}}</ref>

====Grant's situation====
Grant's army had 7,000 men killed and wounded, 3,000 more captured, and 10,000 men who were afraid to fight.<ref name="Daniel249"/> Before being reinforced, he had an estimated 18,000 fighters formed on his Last Line.<ref name="Daniel245"/> 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.<ref name="Cunningham337-338">{{harvnb|Cunningham|2009|pp=337–338}}</ref> At 7:15{{nbsp}}pm, 5,800 fresh troops from Lew Wallace's division arrived at the battlefield and were positioned next to Sherman.<ref name="Gudmens116">{{harvnb|Gudmens|Combat Studies Institute (U.S.), Staff Ride Team|2005|p=116}}</ref> Brigadier General Thomas Crittenden's division from Buell's army began arriving at 9:00{{nbsp}}pm, and two hours later the entire division was at the landing. Eventually, Buell would have nearly 18,000 men available for the battle.<ref name="Gudmens116"/> 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.<ref name="Gudmens116"/>

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."<ref name="Daniel249-250">{{harvnb|Daniel|1997|pp=249–250}}</ref> 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.<ref name="Daniel265-266">{{harvnb|Daniel|1997|pp=265–266}}</ref> Sherman found Grant resting under a tree around midnight, and said: "Well, Grant, we've had the devil's own day, haven't we?"

==Battle, April 7==
Between midnight and 4:00{{nbsp}}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{{nbsp}}am.<ref name="Cunningham340-341">{{harvnb|Cunningham|2009|pp=340–341}}</ref> 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{{nbsp}}am.<ref name="Daniel264">{{harvnb|Daniel|1997|p=264}}</ref> After deducting casualties and those who had abandoned their posts, Beauregard's Confederate army now numbered fewer than 20,000 fighters.<ref name="Daniel278">{{harvnb|Daniel|1997|p=278}}</ref>

===Union counterattacks begin===
[[File:Shiloh Battle April 7.png|thumb|upright=1.25|General overview of April 7|alt=map showing Union armies driving Confederate army south and off the battlefield]]
On the east side of the Union line, Buell's attack began at 5:00{{nbsp}}am with Nelson's three brigades. A few hours later, Nelson was joined on his right by Crittenden.<ref name="Gudmens121">{{harvnb|Gudmens|Combat Studies Institute (U.S.), Staff Ride Team|2005|p=121}}</ref> The two divisions advanced, dispersed enemy skirmishers, and were gradually joined on Crittenden's right by brigades from McCook's division.<ref name="Daniel267-268">{{harvnb|Daniel|1997|pp=267–268}}</ref> McCook did not have all three of his brigades available until close to noon.<ref name="Cunningham357">{{harvnb|Cunningham|2009|p=357}}</ref> 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 Chalmers's Brigade and a makeshift brigade of three regiments. A mix of regiments formed the line further west, and several batteries gave artillery support.<ref name="Daniel269">{{harvnb|Daniel|1997|p=269}}</ref>

At the Davis Wheat Field, a small field between Barnes Field and the Peach Orchard, the brigade commanded by Colonel [[William Babcock Hazen|William B. Hazen]], took more than half of the losses Nelson's division received for the whole day.<ref name="Daniel272">{{harvnb|Daniel|1997|p=272}}</ref> More fighting took place near Sara Bell Field, and after three hours of fighting it became stalemated.<ref name="Daniel274-275">{{harvnb|Daniel|1997|pp=274–275}}</ref> Both sides withdrew around noon, putting Nelson back at Wicker Field.<ref name="Gudmens122">{{harvnb|Gudmens|Combat Studies Institute (U.S.), Staff Ride Team|2005|p=122}}</ref> During this fighting, Hardee was slightly wounded, although he led a counterattack.<ref name="Daniel272"/> West of Nelson, Crittenden and McCook advanced before being forced back to Duncan field.<ref name="Gudmens122"/> At noon, Buell's army had control of the Hornet's Nest.<ref name="Shaara17">{{harvnb|Shaara|2006|p=17}}</ref>

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{{nbsp}}am.<ref name="Gudmens126">{{harvnb|Gudmens|Combat Studies Institute (U.S.), Staff Ride Team|2005|p=126}}</ref> At that time, Cleburne's brigade of 800 men took significant casualties when they unsuccessfully assaulted the Union force.<ref name="Daniel281-283">{{harvnb|Daniel|1997|pp=281–283}}</ref>

===Afternoon fighting===
[[File:BattleOfShilohEndOfSecondDay.png|thumb|upright=1.25|Positions at the end of the second day|alt=map showing Union armies driving Confederate army south and off the battlefield]]
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.<ref name="Gudmens122"/>

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 {{convert|300|yd}}.<ref name="Daniel283">{{harvnb|Daniel|1997|p=283}}</ref> 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.<ref name="Daniel285">{{harvnb|Daniel|1997|p=285}}</ref> Bragg formed another line by Water Oaks Pond, and a two–hour fight ensued with Beauregard personally leading various Confederate units.<ref name="Gudmens126"/>

McCook's westward advance (instead of south), which began at 1:30{{nbsp}}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 repelled the attackers. Soon Beauregard and Bragg were forced back, and Union troops crossed the Hamburg-Purdy Road at 2:30{{nbsp}}pm.<ref name="Gudmens126-127">{{harvnb|Gudmens|Combat Studies Institute (U.S.), Staff Ride Team|2005|pp=126–127}}</ref>

===Beauregard withdraws===
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{{nbsp}}pm.<ref name="Cunningham365">{{harvnb|Cunningham|2009|p=365}}</ref>{{#tag:ref|One historian argues that Beauregard already knew Van Dorn was too far away, since he had been communicating with Memphis by telegraph.<ref name="Daniel301">{{harvnb|Daniel|1997|p=301}}</ref>|group=Note}} At about 2:00{{nbsp}}pm, Breckinridge began forming his corps into a rear guard position near Shiloh Church.

Around 3:30{{nbsp}}pm, the last of the Confederate artillery was hauled away toward Corinth.<ref name="Cunningham367-368">{{harvnb|Cunningham|2009|pp=367–368}}</ref>

Grant and Buell did not pursue the Confederate army, and have been criticized for their decisions.

==Fallen Timbers, April 8==
At 10:00{{nbsp}}am on April 8, Union forces commanded by Sherman and Wood began a pursuit of the Confederate forces.<ref name="Daniel296">{{harvnb|Daniel|1997|p=296}}</ref> 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, [[Terry's Texas Rangers|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' 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.<ref name="Daniel296-297">{{harvnb|Daniel|1997|pp=296–297}}</ref>

Initially, news on the battle was positive for Grant. That changed a week later, especially when a "somewhat exaggerated" newspaper report by [[Whitelaw Reid]] (under a [[pen name]]) was released.<ref name="Daniel304-305">{{harvnb|Daniel|1997|pp=304–305}}</ref> Largely based on testimony from Union deserters and stragglers, the article said that Grant was surprised, and falsely claimed that Union soldiers were bayoneted in their tents. Only Buell, who according to Reid had saved Grant, was treated as a hero.<ref name="Daniel304-305"/> Self-serving accounts from some of Buell's officers also swayed public opinion, and false rumors circulated that Grant had been drunk.<ref name="McPherson414">{{harvnb|McPherson|1988|p=414}}</ref> Among the more justified criticisms of Grant was the lack of fortifications at the camps around Pittsburg Landing; one historian considers this a critical mistake.<ref name="Daniel132">{{harvnb|Daniel|1997|p=132}}</ref> At least two of Grant's generals counseled against entrenching, and Grant believed that enemy troops would not leave their own entrenched position.<ref name="Daniel132"/>

Lew Wallace received criticism for his inability to get his division to the battlefield in a timely manner, and he was eventually removed from Grant's army.<ref name="ABTLewWallace">{{cite web

He may have also lost time by marching down a rugged path through cornfields and pastures.<ref name="Daniel260">{{harvnb|Daniel|1997|p=260}}</ref> Critics also accused him of "dilatoriness", or slow procrastination.

Wallace that had been written by Lew Wallace to her husband on April 5, 1862. The letter provided enough information about Lew Wallace's preparations and route choice that Grant felt Wallace was unjustly criticized—the route selection was justified given that Wallace did not know Sherman had been pushed back and orders did not specify which road to take. These conclusions appeared in ''[[The Century Magazine|Century Magazine]]'' in July 1885 and as a note in ''[[Personal Memoirs of U. S. Grant]]''.<ref name="JSTORWallaceGrant"/><!--p.147--> Wallace's postwar life was more successful as an author, and he became well known for writing the best–selling novel ''[[Ben-Hur: A Tale of the Christ]]''.<ref name="NPSLewWallace">{{cite web

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.<ref name="Chernow208">{{harvnb|Chernow|2017|p=208}}</ref> 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."<ref name="McPherson414"/> Sherman, who could have been one of the battle's scapegoats and did not get along with the press, received more praise than criticism.<ref name="Daniel310">{{harvnb|Daniel|1997|p=310}}</ref> Halleck praised his performance and requested a promotion for him, noting that Sherman had "three horses killed under him" and was wounded twice.<ref name="Scott98"/> Halleck arrived at Pittsburg Landing on April 11 and took personal command—as he had planned earlier. On April{{nbsp}}30, he named Grant as his second-in-command.<ref name="Chernow213">{{harvnb|Chernow|2017|p=213}}</ref> This was a meaningless position, but Halleck's solution to the Grant criticism was a ''[[de facto]]'' suspension that satisfied the critics.<ref name="Daniel309">{{harvnb|Daniel|1997|p=309}}</ref>

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 mentioned Johnston's death. Before the battle, the public had wanted Johnston removed because of the loss of most of Tennessee. Now he was a hero.<ref name="Daniel313">{{harvnb|Daniel|1997|p=313}}</ref> 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.<ref name="McPherson414"/> Eventually, critics began to blame Beauregard for the defeat, citing the lack of a twilight attack on the first day of the battle.<ref name="McPherson414"/>

Confederate President Davis believed that the loss of Albert Sidney Johnston was the "turning point of our fate" in the Western Theater.<ref name="Daniel316">{{harvnb|Daniel|1997|p=316}}</ref> 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]].<ref name="Daniel317">{{harvnb|Daniel|1997|p=317}}</ref> The victory at Shiloh also placed the Union army in a strategic position to infiltrate and capture key points in the south. Waiting until he was fully reinforced and resupplied, Halleck began a "painfully slow" movement to Corinth on April 29.<ref name="Cunningham387">{{harvnb|Cunningham|2009|p=387}}</ref> Arriving on the morning of May 30, Union troops found the city abandoned.<ref name="Cunningham395">{{harvnb|Cunningham|2009|p=395}}</ref> [[Capture of New Orleans|New Orleans]], [[Battle of Baton Rouge (1862)#Background|Baton Rouge]], and [[First Battle of Memphis|Memphis]] were overrun by Union navy forces over the next three months.<ref name="Chernow217">{{harvnb|Chernow|2017|p=217}}</ref> By July, Halleck was promoted to chief of staff in Washington, and Grant became commander of the now larger District of West Tennessee.<ref name="Chernow219">{{harvnb|Chernow|2017|p=219}}</ref> Grant would go on to lead the [[Siege of Vicksburg]], where nearly 30,000 Confederate troops surrendered on July 4, 1863.<ref name="ABTVicksburg">{{cite web
