The Battle of Shiloh (April 6–7, 1862) almost ended Generals Grant and Sherman's careers. Instead, it is considered their first great victory, a testament to their tenacity and determination.

During the chaotic first day, several Union generals played critical roles in holding defensive positions or delaying the Confederate advance. These efforts helped prevent a total collapse of the Union army and bought time for General Ulysses S. Grant to establish a stronger defensive line near Pittsburg Landing.

Lloyd W Klein here looks at how the battle ended in the final part of the series. Part 1 is here.

Ulysses S. Grant.

Important Union Contributions:

·       Brigadier General Benjamin Prentiss who commanded the 6th Division in the Union center. He was a critical first responder given that his was the most forward division. He would then move to the Hornet’s Nest.

·       Major General John A. McClernand who commanded the 1st Division on the Union right flank. McClernand’s division faced some of the heaviest fighting early in the day as the Confederates launched their surprise attack. Despite being pushed back, McClernand’s forces fought stubbornly, slowing the Confederate advance and preventing an early collapse of the Union right flank.

·       Brigadier General Stephen A. Hurlbut, who commanded the 4th Division.

Hurlbut’s division held a defensive position near the Union left flank, covering the approach to Pittsburg Landing.. His troops absorbed significant Confederate pressure and played a key role in protecting the Union army’s retreat and regrouping efforts.

 

Important Confederate Contributions:

·       Major General Braxton Bragg, commander of a Confederate corps, whose aggressive leadership helped drive the Confederate advance early in the battle. He coordinated several assaults on key Union positions, including the Hornet’s Nest, which was crucial in breaking Union resistance in the center. Bragg’s relentless pressure contributed to the Union army’s retreat toward Pittsburg Landing.

·       Major General William J. Hardee, who commanded the lead Confederate corps.

Hardee’s corps spearheaded the initial Confederate assault at dawn, achieving significant success in surprising and overwhelming the Union front lines. His leadership was instrumental in the early Confederate momentum, driving Union forces back several miles.

·       Major General Leonidas Polk who commanded of a Confederate corps. Polk’s corps provided critical support during the Confederate attacks on the Union right flank. While his contributions were solid, Polk’s performance was less decisive compared to Bragg and Hardee. who were instrumental in executing the Confederate attacks, particularly in the early phases of the battle, and their actions shaped the battlefield dynamics.

           

Hornet’s Nest

A key defensive stand occurred at an area later known as the Hornet’s Nest, where Union forces under Prentiss and Brigadier General W.H.L. Wallace held off repeated Confederate assaults for several hours. This resistance bought critical time for Grant to organize a defensive line near Pittsburg Landing. The Hornet’s Nest was a name given to the area of the Shiloh battlefield where Confederate troops made repeated attacks against Union positions along a small, little-used farm road.. Southern soldiers said the zipping bullets sounded like angry hornets; according to tradition, one man said, "It’s a hornet’s nest in there."

The narrow farm road ambles generally southeast from its junction with the Eastern Corinth Road (Corinth-Pittsburgh Road). Fairly level toward its northwest end, it makes a rather sharp climb up a hill near its center, descending again near the William Manse George cabin and the Peach Orchard. That hill, where Brigadier General Benjamin Prentiss commanded an ad hoc group of regiments, comprises the area of the Hornet’s Nest. To Wallace’s right was a division of Federals under Brig. Gen. W.H. L. Wallace, and to his left was another division under Brig. Gen. Stephen Hurlbut. Wallace held a position stretching along the farm road from the Eastern Cornith Road and up the slope to where Prentiss’s line began. Wallace’s men were in a deep ravine on the east side of the farm road; that area is now known as the Sunken Road. Often, but erroneously, the positions of Wallace and Prentiss are lumped together as the Hornet’s Nest. Confusing matters further is the fact that as the farm road passes over the hill where Prentiss had his command, it is sunken for a portion of its 600-yard length there.

Brigadier General W.H.L. Wallace commanded the 2nd Division. An Illinois volunteer soldier who was a lawyer in his civilian life, I believe a law partner at one time of Abraham Lincoln (they were friends, at least). Coolness under fire leading a brigade as a colonel at Fort Donelson had earned him a promotion to Brigadier General Wallace’s division also played a central role in defending the Hornet’s Nest, fighting alongside Prentiss’s men. Wallace was mortally wounded during the battle, but his leadership and the determination of his troops were crucial in holding the line for much of the day. Charles Ferguson Smith had been the division commander but developed a leg infection just prior to the battle. In fact, he died of it a couple of weeks later. General William HL Wallace took command, and ended up defending the Hornet’s Nest for 6 hours, eventually being killed there.

Wallace commanded the 2nd Division of the Army of the Tennessee. His division formed a critical part of the Union line, holding off repeated Confederate assaults. During the intense fighting in the late afternoon, Wallace was mortally wounded. A bullet struck him in the head as his troops were withdrawing from the Hornet’s Nest. He was left on the battlefield during the Union retreat but was later found alive by Union forces. Wallace was taken to a field hospital, but his injuries were too severe. He died on April 10, 1862, four days after the battle. His death was a significant loss to the Union army, as he was a respected and capable commander.

Benjamin Prentiss commanded the 6th Division of the Army of the Tennessee. Early on Day 1, his division bore the brunt of the Confederate surprise attack. Despite being initially driven back, Prentiss regrouped his forces and established a strong defensive position in the Hornet’s Nest, a dense thicket that became a focal point of the battle. Alongside W.H.L. Wallace, Prentiss held this position for hours, slowing the Confederate advance and buying time for Union forces to reorganize near Pittsburg Landing. Prentiss took full command of the position after Wallace was fatally wounded.  Late in the afternoon, after being surrounded and running low on ammunition, Prentiss and his remaining troops were forced to surrender. Prentiss was taken prisoner along with about 2,200 Union soldiers. Prentiss was held as a prisoner of war until he was exchanged in October 1862. His leadership at the Hornet’s Nest earned him recognition for his bravery, despite his capture.

The defense of the Hornet’s Nest by Prentiss and Wallace delayed the Confederate advance, preventing them from reaching Pittsburg Landing and potentially destroying the Union army on Day 1. While both men suffered tragic outcomes—Prentiss as a prisoner and Wallace from mortal wounds—their actions contributed significantly to the Union’s ability to regroup and ultimately win the battle on Day 2. The Confederate forces launched repeated attacks on this strong Union defensive position, but it took hours and significant effort to overcome it.  General Beauregard has been criticized for his conduct of this aspect of the battle because of the time delay it caused. He could have bypassed the Hornet’s Nest entirely and gone straight for Pittsburg Landing.

After the battle he was considered a hero, having held off the Confederate States Army long enough to allow General Grant to organize a counterattack and win the battle. Grant later played down Prentiss's role in the victory, possibly because of mutual dislike between the two generals. He was exchanged in October 1862.  Prentiss was promoted to major general and served on the court-martial board that convicted Fitz John Porter. His dissenting voice in the final vote damaged his political clout in the Army, and he resigned in 1863.

Colonel Randall L. Gibson commanded a brigade under Bragg. Gibson’s brigade launched multiple assaults on the Hornet’s Nest but was repelled repeatedly with heavy losses. His inability to break the Union line underscored the strength of the Union position and the difficulty of the Confederate task. While Gibson would go on to become a long-serving brigade commander with a solid service record, Braxton Bragg (the man who ordered the repeated charges) would fault him and bring him up on charges after the battle. He had graduated Yale as valedictorian, a member of Skull and Crossbones, and the son of a wealthy plantation owner.  An interesting factoid about Gibson is that his great-great-grandfather was a free man of color whose descendants were able to integrate into Louisiana's white society. He would go on to be the US Senator from Louisiana who was instrumental in ending Reconstruction.

An artillery barrage organized by the Ruggles Brigade ultimately caused the Union line to break and the Union line was broken with units heading to the rear. Ruggles' Battery, not an actual unit but a Napoleonic style Grand Battery collecting numerous artillery units under the direction of Confederate division commander Daniel Ruggles. Brigadier General Daniel Ruggles lined up eleven batteries of cannon (62 in all according to Ruggles, 53 according to other sources) and bombed the hell out of the Union troops for nearly an hour beginning at 4:30 PM on April 6th. At the time, this was the greatest concentration of artillery pieces on a North American battlefield.

An uncoordinated double envelopment was in progress. The Confederates eventually surrounded and overwhelmed the Hornet’s Nest, capturing Prentiss and many of his men. However, the delay proved crucial for the Union. Although Prentiss and most of his men were eventually surrounded and captured, their stubborn defense significantly delayed the Confederate advance, allowing Grant to organize a stronger line closer to Pittsburg Landing.

 

The Death of Albert Sidney Johnston

Johnston  personally led a critical charge during the afternoon, inspiring his troops and helping to push Union forces back. A bullet to the back of his knee killed Johnston, where the popliteal artery is located. This wound should not have resulted in death; a simple tourniquet would have been lifesaving. Unfortunately, the wound went unnoticed until too late.

The death of Albert Sidney Johnston of course was a major event in the war; the Confederate western theater never really found its general. Johnston was shot while leading a charge. Why the commanding general was doing this has been speculated about ever since. His losses at Fort Donelson and Henry, and the criticism following his abandoning Nashville certainly occupied his mind. Johnston was killed by a bullet to the back of his knee, where the popliteal artery is located. Unfortunately, the wound went unnoticed until too late because Johnston had received a wound to that leg in the Mexican War, decreasing his sensation. Meanwhile, the bleeding became severe and filled his boot with blood. Essentially he exsanguinated on the field from what ought to have been a non-fatal wound. This wound should not have resulted in death; a simple tourniquet would have been lifesaving.

 

Lew Wallace

A casualty of a different kind was the Union general Lew Wallace. Wallace took a road that was correct if the lines were where they had been at the start of the day but by the time he arrived, those lines were pushed back and so Wallace was behind enemy lines. Thus, he had to countermarch. He never did arrive on day 1 but he was very effective on day 2. Grant never really forgave him; only in his autobiography, after Wallace died, did Grant recognize that he had misinterpreted the situation. Wallace spent years trying to make up for the supposed error, a theme he used in his famous novel Ben Hur.

Lew Wallace is one of the most interesting men who came out of the war, and we have done extensive challenges on almost every aspect of his life. The nature of the misunderstanding that would change his life forever occurred in a flash: at Crump’s Landing, Grant verbally ordered Wallace to the battlefield but didn’t clearly specify what road to take. Wallace ended up on the wrong one (see map). He never did arrive on day 1 (until 7 pm) and Grant never really forgave him. I have read Wallace’s autobiography, and Grant’s Battles and Leaders article and of course his Memoirs.  It all seems like a mix-up of the kind the fog of war will inevitably produce, and way too complicated to review here. Unquestionably, Grant tried to blame Wallace for his day 1 mishaps for many years. Only in his autobiography, after Wallace died, after the wife of the other General Wallace, Mrs. WHL Wallace, sent Grant information that bore out Lew Wallace’s explanation, did Grant recognize that he had misinterpreted the situation. Wallace spent years trying to make up for the supposed error, which was not really his fault, a theme he used in his famous novel Ben Hur. In the interim, Wallace saved Washington DC at the Battle of Monocacy, served as governor of New Mexico territory, and diplomat to the Ottoman Empire. Ben Hur became one of the best sellers of the century, making Wallace a wealthy man, so he did quite well for himself despite it all. He is one of my favorite Civil War characters. And we are not done with him here either.

 

Evening

Grant’s back was to the river; he could have been entirely destroyed. His defense at Pittsburg Landing in the afternoon of day 1 saved his army. By evening, Grant had established a strong defensive line near Pittsburg Landing, supported by artillery and the Tennessee River. The presence of Union gunboats added firepower, repelling further Confederate advances.  Generals Hurlbut and McClernand contributed to this final defensive stand, ensuring the Union army survived the first day of battle.

General Beauregard, confident in the day’s success, decided to halt the attack for the night, believing the Union army was on the verge of collapse. However, this decision allowed Grant to regroup and prepare for a counterattack.

The first day of Shiloh was chaotic and bloody, with heavy casualties on both sides.

The Confederates had pushed the Union forces back significantly but failed to achieve total victory.  The ferocity of the fighting on Day 1 shocked both sides and marked Shiloh as one of the war’s most brutal battles.

That night, reinforcements from Buell’s Army of the Ohio began arriving, giving Grant the strength to launch a counteroffensive on April 7.

Sherman commanded 5th Division, which was stationed at Shiloh Church on the Union right flank. His division was among the first to face the Confederate onslaught.  Despite being surprised and initially overwhelmed, Sherman quickly rallied his troops and organized a defense to slow the Confederate advance. His division absorbed significant pressure, buying time for other Union units to organize and retreat toward Pittsburg Landing.

Shiloh was quite possibly Sherman's best day of combat command during the war.  After being wounded in Rea Field, he galloped back to his camps and got his brigades in line (some were already up and forming) along a ridge overlooking a creek (variously know as Shiloh Branch, Rhea Creek, or Rea Creek).  He was able to hang on here (joined by one brigade from McClernand on his left) from 7 a.m. until 9:30 or so, repelling a series of uncoordinated single-brigade attacks from four Confederate brigades.  Eventually the position was flanked on the left, and Sherman and McClernand fell back to the Hamburg-Purdy Road.  Between 10:30 and 11:30, this position was attacked by a force that one source characterized as "two-thirds of the Confederate army" and driven back to Jones Field.  Sherman and McClernand then carried out the only Federal counterattack of the day, driving the enemy back before losing steam and retiring back to Jones Field in the early afternoon.  In the middle of the afternoon they retired further, across Tilghman Branch..

Sherman demonstrated remarkable composure under fire, personally leading counterattacks and encouraging his men despite being wounded in the hand and shoulder. His ability to maintain discipline and inspire confidence among his troops helped prevent a total rout of the Union right flank. Sherman worked closely with McClernand, whose division was positioned near his own, to establish a series of defensive lines as they fell back under Confederate pressure. Their combined efforts helped slow the Confederate advance and delayed a complete Union collapse.

As the Union forces were pushed back toward Pittsburg Landing, Sherman played a key role in organizing the final defensive line. His leadership ensured that his battered division held its position, contributing to the Union army’s survival at the end of the first day.

Sherman’s ability to rally his troops under chaotic and dire circumstances demonstrated his leadership skills and earned him forever the trust of General Grant. His actions at Shiloh marked a turning point in his career, proving his capability as a battlefield commander. Grant later praised Sherman’s performance, calling him one of the key figures in preventing the Union army from being destroyed on the first day of the battle.

When Sherman arrived at Grant’s headquarters later that evening, he found the general chewing on a soggy cigar in the rain, which had begun soaking the battlefield. ‘Well, Grant, we’ve had the devil’s own day, haven’t we?’ ‘Yes,’ replied Grant, ‘lick ’em tomorrow, though.’

After making a brief attempt to assail Grant's line behind Dill Creek Branch they retired to the Federal camps for the night.  Polk took his Corps back to their own camps of the previous night; which did not help the Confederate effort on the 7th. They slept on their arms. All of the brigades were entangled and exhausted. Command and control had become weak during the afternoon for this reason. Beauregard had thrown in all of his men, there were no reserve units now. He expected the next morning to be a mop-up operation. He did not anticipate Don Carlos Buell’s Army of the Ohio arrival, nor Lew Wallace’s division., which was now on the field. The Confederate lines had become confused and now they were outnumbered. A dispatch from Colonel Benjamin Hardin Helm led Beauregard to believe that Buell was en route to Decatur, Ala., away from Grant’s army. The report was entirely inaccurate, but Beauregard believed it. Cavalry Colonel Nathan Bedford Forrest had observed Buell’s men crossing the river by ferry. He frantically tried to warn Beauregard, but was unable to locate the Confederate commander.

Lew Wallace arrived on the right between 7:00 p.m. and 7:30 p.m.  On the left, Nelson's Division of Buell's Army was just beginning to cross as the Confederates made their final effort, and finished by 9:00 p.m.  Crittenden was in place by 1:00 a.m., and McCook followed after that. Buell arrived that same evening with nearly 20,000 men. Wallace’s division, consisting of about 5,800 men, was well-rested and unscathed from the previous day’s fighting. These reinforcements completely changed the balance of forces, but Beauregard didn’t know it was happening.

 

The Battle – Day 2

The fortunes of Day 2 went the opposite way. Beauregard’s men were entangled and exhausted. Don Carlos Buell’s Army of the Ohio arrived. But so did Lew Wallace’s division.

General P.G.T. Beauregard had effectively managed the Confederate forces after Johnston’s death, but his decision to halt the attack on the evening of April 6 had significant consequences. He believed the Union army was defeated and delayed further attacks until the next day, giving Grant time to regroup and receive reinforcements.

Overnight, Union reinforcements under General Don Carlos Buell and Lew Wallace arrived, significantly bolstering Union forces. Early on April 7, Union forces launched a coordinated counterattack against the Confederate army, which had been exhausted from the previous day’s fighting. Confederate troops, under General P.G.T. Beauregard (put up stiff resistance but were gradually pushed back.

After failing to reach the battlefield in time on Day 1 due to miscommunication and delays, Wallace’s troops arrived fully intact and ready for action, making a significant contribution to the Union counteroffensive.  His troops were positioned on the Union right flank, where they attacked the Confederate left, putting additional pressure on the exhausted Southern forces. Wallace’s division executed a coordinated attack with other Union forces, pushing the Confederate left flank back. This disrupted the Confederate defensive lines and contributed to their eventual retreat. His troops were instrumental in recapturing ground lost on Day 1, helping secure Union control of the battlefield. Wallace’s arrival helped General Ulysses S. Grant execute a unified counteroffensive across the entire front. Wallace’s division worked in conjunction with Buell’s reinforcements and other Union divisions to overwhelm the Confederates.

The Union counterattacked the morning of day 2. Sherman’s division participated in the Union counteroffensive, helping to drive the Confederate forces back. His troops, though exhausted and bloodied from the previous day’s fighting, played a significant role in regaining lost ground and securing a Union victory. The Union army recaptured lost ground, including areas around Pittsburg Landing. .By afternoon, the Confederate forces, realizing they were outnumbered and outmaneuvered, began retreating toward Corinth, Mississippi.

The Confederate lines had become confused the day before and now they were outnumbered. The Union now had the advantage and pushed the lines back completely beyond where the battle lines had been before the fighting began.

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. General Don Carlos Buell’s troops made a critical contribution, no doubt. His added reinforcements helped ensure a Union victory on the battle’s second day when a massive Union counterattack routed Confederate forces. Buell’s soldiers played a key role in the Union counterattack. They attacked the Confederate right flank, forcing the Confederates to stretch their already exhausted lines. This pressure, combined with attacks from other Union forces, gradually drove the Confederates back. Buell’s troops helped stabilize the Union’s left flank, which had been vulnerable on Day 1.Their presence allowed Grant to organize a coordinated assault across the entire line, rather than focusing solely on defense. The fresh energy and discipline of Buell’s troops were instrumental in breaking the Confederate resistance. By mid-afternoon, their efforts contributed to forcing the Confederates into a full retreat, ensuring a Union victory. Buell’s timely arrival and the effectiveness of his troops underscored the importance of reinforcements in Civil War battles, where exhaustion and attrition often determined the outcome. General Buell would later insist that he deserved credit for turning the tide at Shiloh, while others—in particular Ulysses S. Grant and William T. Sherman—argued that his troops ultimately had little effect on the outcome. In summary, both Grant’s and Buell’s armies made important contributions on day 2.

Could Beauregard have won day 2 if he had prepared differently? For many years, this was the conclusion of many historians. 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, and low ammunition. Dill Creek Branch would have been a formidable position to capture by tired troops. On April 7, Beauregard attempted to continue offensive operations, but his troops were outnumbered, exhausted, and lacked reinforcements. Recognizing the arrival of Union reinforcements, Beauregard could have shifted to a defensive posture, fortifying positions and conserving his forces for a controlled retreat. This might have minimized casualties and preserved his army for future campaigns. On day 2, the Confederates were outnumbered but had they entrenched and set up a defensive perimeter, they might well have held off the Union counterattack. Beauregard could have ordered a relentless night attack to exploit the disarray in the Union lines. While risky due to exhaustion and poor visibility, this might have prevented Union reinforcements (Buell’s and Wallace’s troops) from stabilizing the Union position overnight. Confederate cavalry under Nathan Bedford Forrest was underutilized during the battle, particularly for reconnaissance and disrupting Union reinforcements. Beauregard could have deployed cavalry more aggressively to harass Buell’s approaching forces or cut off the Union supply lines to Pittsburg Landing. This could have delayed or weakened the Union counteroffensive on Day 2. He could have anticipated Buell’s arrival and adjusted his strategy accordingly, perhaps by retreating under cover of darkness on April 6 to avoid being outflanked and overwhelmed. Finally, his single road route from Corinth was problematic logistically, as ammunition would become depleted.

The Aftermath

Beauregard retreated from the field in the late afternoon and returned to Corinth. The Union Army had recovered all of the ground it had lost on day 1 and swept the field on day 2. Grant did not pursue, in part because his own army was in disarray but also because General Halleck would not allow it. Both sides suffered significant losses, with over 23,000 combined casualties, making Shiloh one of the bloodiest battles of the Civil War up to that point. The Union army claimed victory, though at a heavy cost.

The Union had 63,000 men engaged, with 13,000 casualties (1754 killed, 8400 wounded, 2900 captured vs. the Confederates with 40-45,000 men with 10,700 casualties (1728 killed, 8000 wounded, 1000 captured). The Union therefore had more casualties, but on a percentage basis, a slightly lower rate of casualties. The battle demonstrated the brutality of the war and marked a turning point in the Western Theater, giving the Union control of key regions in Tennessee. “Scareder than I was at Shiloh” The battle remains famous for the brutal fighting, the high casualties on both sides, and the evidence that the war was going to be a long one. At that time, this battle had more American casualties than every prior war combined! Yet by the end of the war, this battle barely made the top ten list.

General Grant initially was the recipient of an outpouring of public support at first, hailed as a hero of a great battle. The perception of Grant as a drunkard was utilized to explain the horrific losses suffered at the Battle of Shiloh by officers jealous of Grant’s rapid rise. Newspaper reports critical of Grant’s command were intended to increase sales, if not influence the political debate, after the shocking casualties of that bloody battle. Shocked by the casualties of what, up to that point, was the war’s bloodiest battle, newspaper reporters wrote articles critical of Grant’s command. These criticisms fed the rumors that Grant, who many believed had been forced out of the pre-war Army because of alcohol consumption, had been caught drunk and off guard by Confederate General Albert Sydney Johnston’s surprise attack. The losses suffered by both sides at Shiloh had more to do with the nature of nineteenth-century warfare than the nature of Grant’s relationship with liquor, but rumors of his affection for spirits now became generally accepted.

Whitelaw Reid, Cincinnati Gazette, reported the events of the battle incorrectly, stating that Grant had been taken by surprise at Shiloh and that soldiers had been bayonetted in their tents. This myth persists to this day.  The high casualty rate at Shiloh was related to the intensity of the battle, not the nature of Grant’s problems with liquor, but rumors of his drinking increased.

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. Some of the more "savage denunciations" of Grant came from politicians representing Ohio and Iowa. 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."

On April 8, Confederate President Jefferson Davis reported to the Confederate congress that 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. 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 Battle of Shiloh (April 6–7, 1862) almost ended Generals Grant and Sherman's careers. Instead, it is considered their first great victory, a testament to their tenacity and determination.

General PGT Beauregard planned a surprise advance and attack at Pittsburg Landing, on the west bank of the Tennessee River. On the first day, the Confederate Army routed the Union Army and only tenacious defense saved the day. On the second day, Union reinforcements and Rebel confusion led to a complete reversal of the fortunes of day 1.

Lloyd W Klein explains in part 1 in this series.

Battle of Shiloh by Thure de Thulstrup.


Planning and Strategy

Maj Gen Don Carlos Buell and the Army of the Ohio had taken Nashville in February 1862. He was able to claim the city with minimal effort in February 1862, and was promoted to major general shortly thereafter. In March 1862 General Henry Halleck ordered Buell to move south to rendezvous with General Ulysses S. Grant and the Army of the Tennessee at Pittsburg Landing, TN. Union leadership realized that its troops were too spread out, so it was decided to concentrate the troops. Recognizing this impending combining of forces, the Confederates were compelled to act.

After the losses at Forts Henry and Donelson and the abandonment of Nashville, the various Rebel armies converged on Corinth, Mississippi. This was a malarial-infested river town and a poor location for a retreating army.  However, Corinth was the junction of 2 major railroads, the Memphis & Charleston RR and the Mobile & Ohio RR, and hence was a critical railroad crossroads, it was a convenient place to concentrate. Johnston’s command had only about 17,000 troops, so he joined his forces with those under General Polk. Because of Corinth’s centrality, he was able to gather 40-45,000 troops. This was probably sufficient to face Grant alone, who had about 48,000, but not combined with Buell., with an additional 18-20,000. Hence, a pre-emptive action to prevent their joining was a necessity.

Exactly how involved Albert Sidney Johnston was in planning the attack is controversial; it has been suggested that he was totally out of his depth and that Beauregard both planned and led the attack. The broad concept was to attack Grant before Buell joined him. Another error was that the rains had slowed travel from their base in Corinth.  Had they arrived a day sooner General Buell might not have gotten there in time for day 2.

General Charles Ferguson Smith was at the time commander of the Union Army, as Halleck tried to dump Grant behind the scenes. Sherman went upstream with his division to raid the Memphis & Charleston RR, but on the way noted Pittsburg Landing and sent a recommendation to Smith that he occupy it. Smith sent Hurlbut, who occupied the landing. Upon Sherman's return from his unsuccessful raid, he landed there, decided the ground was good, and took charge of the forces around the landing and occupied Shiloh Church, on the west bank. Grant probably made an error in setting up camp on the side of the river closest to the known position of the Confederate Army. Grant’s back was to the river, and he could have been destroyed.

Sherman had set up camp around the Shiloh Church. Grant probably made an error in setting up camp on the side of the river closest to the known position of the Confederate Army. Grant’s back was to the river, and he could have been entirely destroyed. Pittsburg Landing is nine miles upriver (south) of Savannah, and it had a road that led to Corinth, Mississippi. About three miles inland from the landing was a log church named Shiloh (a Hebrew word meaning "place of peace”.  It seemed like a good choice at the time because it was away from the river and on land that was well-drained and open. The area 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 stealthiness of Beauregard's plan depended on speed. The march from Corinth is less than 20 miles and should have taken trained troops one day to approach and form for an assault. The rebel troops were untrained, to put it mildly, and the march took 3 days. Beauregard's biggest mistake in planning was the initial formation with each Corps spread across the front one behind the other. Commanding such a formation on a Corps level was impossible and not long after the jump off command responsibilities were separated in a more logical distribution of authority. Since the rebels were so untrained, Corps level identity wasn't strong. Beauregard underestimated the length of time to march from their camps to the area of Pittsburgh Landing.  This resulted in many of their troops not having enough rations and they then stopped their initially successful assault in order to feast at the Union campsites. Another error was that the rains had slowed travel from their base in Corinth.  Had they arrived a day sooner Buell might not have gotten there in time for day 2. In fact, the whole idea was to attack Grant before Buell joined him.

No one in the Union Army expected Beauregard to suddenly appear on their south flank. The divisions of Sherman and Prentiss were the least experienced, so when they bolted, it seemed to be a general retreat. Sherman had heard the reports of enemy soldiers in the area but he was concerned that if he entrenched, it would be viewed that his “insanity” regarding the war had returned so he ignored it. The lack of entrenchments was a distinct disadvantage for the Union troops and made the battle a "stand-up" fight for most of the day.

The camp alignment was designed for camping convenience and contributed to a more or less piecemeal resistance at first, but did help in a "defense-in-depth" resistance to the Confederate onslaught. Also having Sherman at the front right from the beginning turned out to be fortunate.

Every West Point trained officer (Halleck , Grant, Smith, Sherman, and McPherson) believed that Johnston and Beauregard would hold their troops behind the Corinth entrenchments and await the Union Army. Every day there were orders from Halleck in St Louis to Grant for him NOT to bring on a battle by any aggressive moves.

 

Order of Battle

Union Army

Major General Halleck served as the Commander of the Department of the West, with his headquarters located in St. Louis. A member of the Democratic Party, Halleck's intellectual approach contrasted sharply with that of his predecessor, Fremont. Although he was known for his cautious demeanor and did not fully endorse Grant's aggressive tactics, President Lincoln urged him to devise an offensive strategy. It is possible that Halleck harbored some distrust towards Grant, and perhaps even felt envious of the latter's achievements up to that point.

Major General Ulysses S. Grant held the position of commander for the District of West Tennessee and the XIII Corps, operating from the field. After being released from what could be described as house arrest at Fort Henry, he arrived in Savannah, Tennessee, on March 23, 1862. Grant assumed the role of Senior Officer Present (SOP) for the Tennessee River Expedition, which is often referred to as either the Army of the Tennessee or simply Grant's Army. He established his headquarters at the Cherry House, situated on a ridge overlooking Savannah. Following his victories at Fort Henry and Fort Donelson, Grant was promoted to Major General. However, Halleck had recently removed him from field command of the expedition after Grant left his district to meet Buell in Nashville, failed to report on his troop strength, and allegedly did not promptly halt looting at the captured forts. It was later revealed that Halleck's inquiries regarding Grant's forces had not reached him.

Halleck also mentioned concerns about rumors of Grant's potential return to alcohol consumption but ultimately reinstated him to field command. This decision may have been influenced by pressure from Lincoln and the War Department. When Halleck communicated the reinstatement to Grant, he framed it as an effort to rectify an injustice, omitting the fact that the initial injustice had originated with him. In response to Grant's letter expressing concern about possible adversaries between them, Halleck assured him, "You are mistaken. There is no enemy between you and me."

Major General Don Carlos Buell served as the Commander of the Department of the Ohio and the Army of the Ohio, although he held a junior rank compared to General Grant based on their respective dates of appointment. Following the capture of Fort Donelson, Buell's command was placed under the authority of General Halleck, who subsequently ordered him to advance from Nashville to Savannah. By April 1, 1862, Buell's leading division, under the command of Brigadier General Nelson, was still a week away from reaching Savannah. Buell, who had recently transitioned from being Halleck's equal to a subordinate, was recognized for his exceptional organizational skills, making Halleck's decision to assign him to this task a prudent one. In November 1861, Buell was dispatched to the Western Theater of the war in Kentucky, where he took command of the Army of the Ohio. He received directives from President Abraham Lincoln and General George B. McClellan to launch an invasion into eastern Tennessee. However, citing insufficient transportation for his large force of over 50,000 troops, Buell opted to advance on Nashville instead, capturing the city with relative ease in February 1862, which led to his promotion to major general shortly thereafter.

The next in seniority, Major General John McClernand, served as the commander of the 1st Division but had been assigned the role of garrison commander at Savannah. Following him in the chain of command was Major General C.F. Smith, who, while serving as a division commander, took on the responsibilities of the Tennessee River Expedition Commander during a period when Grant was occupied at Fort Henry and McClernand was relegated to garrison duties. Unfortunately, Smith became incapacitated due to a leg injury sustained while attempting to board a rowboat, which prevented him from participating in the Battle of Shiloh. He ultimately succumbed to an infection and dysentery a few weeks later, leading to Brigadier General William H.L. Wallace taking over his position.

Brigadier General William T. Sherman commanded a newly formed division. He was positioned as the forward leader of the Expedition at the Pittsburgh Landing campsite. Previously, Sherman led the 5th Division, but his pessimistic outlook on the war resulted in a breakdown that necessitated a brief leave of absence. After recovering, he established a strong partnership with Grant that would ultimately change the course of the war. At this moment, he was commander of a division under Grant.

 

The next most senior officer, Major General Lew Wallace, serves as a division commander and is stationed at Crumps Landing, located just upstream from Savannah. The other division commander under Grant's command was Benjamin Prentiss, who led the 6th division.

 

Confederate Army

Albert Sidney Johnston was a respected officer in the antebellum army, and his decision to join the Confederacy was seen as a significant advantage for the South. A West Point graduate, he gained recognition as a hero during the Mexican War. He rose to the rank of colonel in the distinguished 2nd US Cavalry, where Robert E. Lee served as his lieutenant colonel, and notable figures such as William Hardee and George Thomas held the rank of major. At the onset of the Civil War, Johnston was in command of the Department of the Pacific, which led President Davis to appoint him as a full general, placing him second in seniority, just behind Samuel Cooper. Subsequently, he was assigned to lead the western theater of operations. Following Zollicoffer’s defeat at Mill Springs, Davis appointed PGT Beauregard to serve under Johnston. However, the setbacks at Fort Henry, Fort Donelson, and Nashville raised concerns regarding Johnston's effectiveness. His tenure was marked by a mix of successes and failures; he took command in Tennessee in September 1861 after Polk's breach of Kentucky's neutrality and occupation of Columbus, Kentucky. From his base in Bowling Green, Kentucky, he projected a strong front that unsettled both Major General Robert Anderson and Brigadier General Sherman, who were in charge of the Department of the Ohio, while the current commander, Major General Buell, adopted a notably cautious approach. Nevertheless, Johnston's oversight of the river forts along the Cumberland and Tennessee rivers was lacking, allowing Grant's Tennessee River Expedition to capture both forts and Nashville.

PGT Beauregard stepped down from his position as commandant at West Point to take charge of Charleston Harbor, where he oversaw the bombardment of Fort Sumter and the events at the First Battle of Manassas.

The organizational structure of the Confederate army included the First Corps under Leonidas Polk, the Second Corps led by Braxton Bragg, the Third Corps commanded by William Hardee, and the Reserve Corps under John C. Breckinridge. This assembly essentially represented a reunion of the US 2nd Cavalry, orchestrated by Secretary of War Jefferson Davis, who was joined by the former Vice President of the United States. This alignment was likely intentional, as Davis had been preparing for the impending conflict long before it officially commenced.

The Battle – Day 1

Beauregard underestimated the time necessary to march from their camps outside of Corinth to the area of Pittsburgh Landing.  This resulted in many of their troops not having enough rations. One consequence was that after their initially successful assault, the Confederate forces halted to feast at the Union campsites.

Surprise Attack

Strategically, the rebel assault was definitely a surprise, but tactically it was most assuredly NOT a surprise. Like calling Gettysburg a meeting engagement, it depends on exactly what we mean by the word “surprise”. There was no prepared defensive line and no entrenchments, and no one expected an attack or a battle in that location. Only a few pickets were in place. So from a preparedness perspective, it was a surprise. But there had been a minor skirmish on April 4th. There were myriad reports of Confederates in the area.

At midnight April 5, Colonel 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 to Seay Field. Around 5 am, Confederate pickets fired at Powell’s men. When Powell advanced into Fraley’s Field, he ran into Major Hardcastle’s 3rd Mississippi Battalion. When General Johnston heard the sounds of battle, he gave Beauregard a fateful order. Meanwhile, Powell sent back word that he had run into a Confederate force of several thousand. When Prentiss heard this report, he had an odd response. Sherman also had a weird response until an event occurred he could not ignore.

Colonel Everett Peabody had ordered a reconnaissance by 3 companies at midnight on April 5 and a sighting was made. That was when the battle began. Colonel Everett Peabody of the 25th Missouri was a new brigade commander in General Prentiss' new division and were the most southerly camped troops near the Shiloh branch Creek. Because of many days of encountering rebels in the woods and on the roads by pickets and cavalry, Colonel Peabody was very nervous and worried on the night of April 5 into the early morning of April 6. About 1:00 am Peabody sent out Major James Powell of the 25th with a small patrol that soon returned with word he had encountered Confederate pickets very close. Peabody organized a larger patrol and they went out at 3:00am. Powell found Hindman's Confederate division advancing and attacked. One of the ironies of Shiloh was that this large battle began with an attack by Union soldiers. Eventually Powell figured the rebels were too strong and began a fighting withdrawal back to the Union camps. Prentiss at first was outraged that Peabody had provoked an attack unordered, But then realized what it meant.  And Peabody basically saved the Union army by giving them time to prepare. Sherman didn’t believe it until he went forward to see for himself and was wounded slightly while an aide was killed.

At 5:30 am, Johnston ordered a general attack but it took at least 2 hours to organize and even then the alignment was off axis. Hardee and Bragg began the assault with a 3 mile wide line. At 7:30 am, the corps of Polk and Breckinridge moved forward on the flanks, extending the line and causing intermixing of commands. In essence the attack was one very long frontal attack. The idea was to drive the Union camps back to Owl Creek, away from the river (NOT into it, which is a common misconception), which should have meant an attack primarily on the Union left.

At dawn, Confederate forces under General Albert Sidney Johnston and General P.G.T. Beauregard launched a surprise attack on Union troops encamped near Pittsburg Landing in southwestern Tennessee. Johnston aimed to defeat the Union army before reinforcements under General Don Carlos Buell could arrive.

The firing became almost continuous and swelled so Peabody, Sherman, Prentiss, and their men knew something big was happening, but Prentiss and Sherman needed a little more persuading.

Grant maintained in his Memoirs that it was not a surprise attack.  The northern newspapers exaggerated the nature of the surprise at the time; indeed the Union did not entrench but Sherman had been forewarned and elements of the Union army found the southern lines quite soon. Halleck would help Grant cover for whatever surprise it was, in large part because it was a victory in the end. Of course, this view was beneficial to Grant, and also to Halleck at the time, to keep themselves from being embarrassed, or even relieved of command.  It is still controversial whether or not Union soldiers were really bayoneted in their tents and shot in their underwear as was reported in the papers, but most modern accounts say that was an exaggeration.

Grant was having breakfast in Savannah. When he heard the sounds of battle, he ordered General Nelson forward, took his steamboat to Crump’s Landing where he ordered Lew Wallace to prepare to move. then got to Pittsburg Landing at about 9am. He was on crutches, as he had fallen from his horse recently.

The Union forces were caught off guard, with many soldiers still in their tents or eating breakfast when the attack began. The Confederate assault overwhelmed the Union front lines, pushing them back toward the Tennessee River.

The Union army, spread across multiple camps, was unprepared for the intensity of the attack. Many units were quickly overrun, and disorganized Union troops retreated in panic.

The nature of the surprise was exaggerated by the northern newspapers at the time; the Union did not entrench, but General Sherman had been forewarned and elements of the Union army found the southern lines quite soon after their arrival. Despite being routed early, Sherman showed tenacity and skill despite adversity on the first day, proving to himself and to others that he had the emotional and cognitive skills necessary to lead an army.

The Battle of Shiloh in April 1862 is perhaps one of the most overlooked in its overall importance to the outcome of the US Civil War. In this article Curtis J. Smothers explains the battle and how it impacted the war.

The Battle of Shiloh. By Thure de Thulstrup.

The Battle of Shiloh was one of the bloodiest battle ever fought on US soil up to its time, with over 23,000 dead, 13,000 of whom were northerners. But the battle’s outcome had more far-reaching effects:

 

·       Shiloh nearly ruined the career of Union General U.S. Grant

·       The battle also cost the Confederacy one its best generals, Albert S. Johnston, who was shot in the leg while riding in the thick of battle

 

However, Shiloh’s importance lies in how it changed Grant's thinking and how it set the stage for Union domination of the Mississippi River, Grant’s going east and the eventual defeat of the Confederacy.

 

The sobering reality of the war to come

After Shiloh, Grant realized firsthand that the South would not be easily beaten. Before Shiloh, and based on his earlier easy victories at Fort Henry and Donelson, Grant had scant respect for the Confederate fighting spirit and ability. After the carnage and near defeat of his bivouacked, green Union troops, who ran from the hordes of yelling rebels and cowered by the river bluffs, Grant came to know what his subordinate and friend, William Tecumseh Sherman, knew: the war would last for years, and the South would have to be completely crushed.

 

Grant’s green troops bivouacked, but didn’t dig on

The Battle of Shiloh took place on the western bank of the Tennessee River, where Grant had ferried his nearly 50,000-man army to place called Pittsburg Landing. (Much of the bloodiest fighting took place around a church called "Shiloh," whose name, ironically, is derived from the Hebrew for "peace.") Grant's plans were to wait for reinforcement from General Don Carlos Buell and strike out at the Confederacy with his superior forces with the goal of capturing the major Confederate rail junction at Corinth, Mississippi. Grant, who was not prone to digging in or building entrenchments, figured his raw troops needed to be drilled and shaped up.

 

Confederates could have won

In the early morning hours of April 6, 1862, Grant was totally surprised by the Confederates, who overran Yankee camps that had failed to even post patrols.

In the ebb and flow of the battlefield on the first day, it was only through the lack of good tactical leadership, experience and good weaponry on the part of the Confederates that prevented a total Yankee defeat at Shiloh. Confederate General Johnston's biggest mistake was going to the battle front. He left orders to his subordinate Beauregard to stay behind and execute the battle plan of cutting off the Yankee retreat to the river, but Beauregard had a different plan, which was to run straight ahead and push the Yankees into the river. As Johnston bled to death after a leg wound, daylight waned and Confederate hopes of victory also died.

 

Beauregard decided to wait until the next day

The battle of the first day ended after Grant and Sherman rallied to stabilize the Yankee positions. Beauregard, however, figured that he had the better of Grant and would finish off the Yankees the next day. Beauregard also figured that he still outnumbered Grant, but Yankee General Buell's reinforcements arrived the next morning; and Grant's subordinate, General Lew Wallace (the man who wrote the epic Ben-Hur) whose division had taken the wrong road the day before, finally showed up for duty.

Fortunately for the Union, the second day of Shiloh saw a revitalized Yankee force and a massive counterattack that relentlessly pushed the depleted Southerners back towards Corinth, Mississippi.

 

Grant took a beating in the press, but Lincoln rehabilitated this fighting general

The battle was over, but the recriminations and controversy would continue. Beauregard would be vilified for not pressing his advantage at the end of the first day. Grant would take a beating in the northern press for the massive Union casualties, and would be relieved by General Halleck and demoted to a do-nothing second-in-command position.

In the end, though, Lincoln moved Halleck to Washington, D.C., and gave Grant back command in the West. (Lincoln recognized Grant as a fighter not prone to the "slows" like many other Union generals)

Grant would go on to amass an astonishing record of victories in the west that would culminate in the capture of Vicksburg that would split the Confederacy at the Mississippi. After victories in Tennessee, Grant would come east to eventually end the war. Sherman would go South and due east cutting a swath of destruction that would isolate and cripple the Confederacy. 

 

Shiloh forged a winning team

The victory of Shiloh solidified the relationship of Grant and Sherman and led them to a more realistic appreciation of the war. Likewise, all the principal victories of the North (out West) in 1863 and 1864 were made possible. If Johnston's Confederate forces won at Shiloh on April 6, the land-naval campaign against Vicksburg, the March to the Sea, and the Siege of Petersburg (below the Confederate capital) might not have occurred at all.
