The Second Battle of Corinth (which, in the context of the American Civil War, is usually referred to as the Battle of Corinth, to differentiate it from the siege of Corinth earlier the same year) was fought October 3–4, 1862, in Corinth, Mississippi. For the second time in the Iuka–Corinth Campaign, Union Major General William S. Rosecrans defeated a Confederate army, this time one under Maj. Gen. Earl Van Dorn.
After the Battle of Iuka, Maj. Gen. Sterling Price marched his army to meet with Van Dorn's. The combined force, known as the Army of West Tennessee, was put under the command of the more senior Van Dorn. The army moved in the direction of Corinth, a critical rail junction in northern Mississippi, hoping to disrupt Union lines of communications and then sweep into Middle Tennessee. The fighting began on October 3 as the Confederates pushed the Union Army from the rifle pits originally constructed by the Confederates for the siege of Corinth. The Confederates exploited a gap in the Union line and continued to press the Union troops until they fell back to an inner line of fortifications.
On the second day of battle, the Confederates moved forward to meet heavy Union artillery fire, storming Battery Powell and Battery Robinett, where desperate hand-to-hand fighting occurred. A brief incursion into the town of Corinth was repulsed. After a U.S. counterattack recaptured Battery Powell, Van Dorn ordered a general retreat. Rosecrans did not pursue immediately and the Confederates escaped destruction.
Background
Military situation
As Confederate General Braxton Bragg moved north from Tennessee into Kentucky in September 1862, Union Maj. Gen. Don Carlos Buell pursued him from Nashville with his Army of the Ohio. Confederate forces under Van Dorn and Price in northern Mississippi were expected to advance into Middle Tennessee to support Bragg's effort, but the Confederates also needed to prevent Buell from being reinforced by Maj. Gen. Ulysses S. Grant's Army of the Tennessee. Since the conclusion of the siege of Corinth that summer, Grant's army had been engaged in protecting supply lines in western Tennessee and northern Mississippi. At the Battle of Iuka on September 19, Maj. Gen. Sterling Price's Confederate Army of the West was defeated by forces under Grant's overall command, but tactically under Rosecrans, the commander of the Army of the Mississippi. (Grant's second column approaching Iuka, commanded by Maj. Gen. Edward Ord, did not participate in the battle as planned. An acoustic shadow apparently prevented Grant and Ord from hearing the sounds of the battle starting.) Price had hoped to combine his small army with Maj. Gen. Earl Van Dorn's Army of West Tennessee and disrupt Grant's communications, but Rosecrans struck first, causing Price to retreat from Iuka. Rosecrans's pursuit of Price was ineffectual.
After Iuka, Grant established his headquarters at Jackson, Tennessee, a central location to communicate with his commands at Corinth and Memphis. Rosecrans returned to Corinth. Ord's three divisions of Grant's Army of the Tennessee moved to Bolivar, Tennessee, northwest of Corinth, to join with Maj. Gen. Stephen A. Hurlbut. Thus, Grant's forces in the immediate vicinity consisted of 12,000 men at Bolivar, Rosecrans's 23,000 at Corinth, Maj. Gen. William T. Sherman's 7,000 at Memphis, and another 6,000 as a general reserve at Jackson.
Price's army marched to Ripley where it joined Van Dorn on September 28. Van Dorn was the senior officer and took command of the combined force, numbering about 22,000 men. They marched on the Memphis and Charleston Railroad to Pocahontas, Tennessee, on October 1. From this point they had a number of opportunities for further moves and Grant was uncertain about their intentions. When they bivouacked on October 2 at Chewalla, Grant became certain that Corinth was the target. The Confederates hoped to seize Corinth from an unexpected direction, isolating Rosecrans from reinforcements, and then sweep into Middle Tennessee. Grant sent word to Rosecrans to be prepared for an attack, at the same time directing Hurlbut to keep an eye on the enemy and strike him on the flank if a favorable opportunity offered. Despite the warning from Grant, Rosecrans was not convinced that Corinth was necessarily the target of Van Dorn's advance. He believed that the Confederate commander would not be foolhardy enough to attack the fortified town and might well instead choose to strike the Mobile and Ohio railroad and maneuver the Union soldiers out of their position.
Along the north and east sides of Corinth, about two miles from the town, was a line of entrenchments, extending from the Chewalla Road on the northwest to the Mobile and Ohio Railroad on the south, that had been constructed by Confederate General P.G.T. Beauregard's army before it evacuated the town in May. These lines were too extensive for Rosecrans's 23,000 men to defend, so with the approval of Grant, Rosecrans modified the lines to emphasize the defense of the town and the ammunition magazines near the junction of the two railroads. The inner line of redoubts, closer to the town, called the Halleck Line, was much more substantial. A number of formidable named batteries, guns positioned in strong earthwork defenses, were part of the inner line: Batteries Robinett, Williams, Phillips, Tannrath, and Lothrop, in the area known as College Hill. They were connected by breastworks, and during the last four days of September these works had been strengthened, and the trees in the vicinity of the centrally placed Battery Robinett had been felled to form an abatis. Rosecrans's plan was to absorb the expected Confederate advance with a skirmish line at the old Confederate entrenchments and to then meet the bulk of the Confederate attack with his main force along the Halleck Line, about a mile from the center of town. His final stand would be made around the batteries on College Hill. His men were provided with three days' rations and 100 rounds of ammunition. Van Dorn was not aware of the strength of his opponent, who had prudently called in two reinforcing divisions from the Army of the Tennessee to deal with the difficulty of assaulting these prepared positions.
Opposing forces
Union
Rosecrans's Army of the Mississippi was organized as follows:
Confederate
Van Dorn's combined Confederate Army of West Tennessee was organized as follows:
- Price's Corps, also known as the Army of the West, with two divisions commanded by Brig. Gen. Louis Hébert (brigades of Brig. Gen. Martin E. Green and Colonels Elijah Gates, W. Bruce Colbert, and John D. Martin) and Brig. Gen. Dabney H. Maury (brigades of Brig. Gens. John C. Moore and William L. Cabell, and Brig. Gen. (acting) Charles W. Phifer).
- The 1st Division of the District of the Mississippi, commanded by Maj. Gen. Mansfield Lovell, with the brigades of Brig. Gens. Albert Rust, John B. Villepigue, John S. Bowen, and a cavalry brigade commanded by Col. William H. Jackson, and Major St. L. Dupiere's Louisiana Zouave battalion.
Battle
October 3
On the morning of October 3, three of Rosecrans's divisions advanced into the old Confederate rifle pits north and northwest of town: McKean on the left, Davies in the center, and Hamilton on the right. Stanley's division was held in reserve south of town. Van Dorn began his assault at 10 a.m. with Lovell's division attacking McArthur's brigade (McKean's division, on the Union left) from three sides. Van Dorn's plan was a double envelopment, in which Lovell would open the fight, in the hope that Rosecrans would weaken his right to reinforce McKean, at which time Price would make the main assault against the U.S. right and enter the works. Lovell made a determined attack on Oliver and as soon as he became engaged Maury opened the fight with Davies's left. McArthur quickly moved four regiments to Oliver's support and at the same time Davies advanced his line to the entrenchments. These movements left a gap between Davies and McKean, through which the Confederates forced their way about 1:30 p.m., and the whole Union line fell back to within half a mile of the redoubts, leaving two pieces of artillery in the hands of the Confederates.
During this part of the action Gen. Hackleman was killed and Gen. Oglesby (the future governor of Illinois) seriously wounded, shot through the lungs. About 3 p.m. Hamilton was ordered to change front and attack the Confederates on the left flank, but through a misunderstanding of the order and the unmasking of a force on Buford's front, so much time was lost that it was sunset before the division was in position for the movement, and it had to be abandoned. Van Dorn in his report says: "One hour more of daylight and victory would have soothed our grief for the loss of the gallant dead who sleep on that lost but not dishonored field." But one hour more of daylight would have hurled Hamilton's as-yet unengaged brigades on the Confederate's left and rear, which would in all probability have driven Van Dorn from the field and made the second day's battle unnecessary.
So far the advantage had been with the Confederates. Rosecrans had been driven back at all points, and night found his entire army except pickets inside the redoubts. Both sides had been exhausted from the fighting. The weather had been hot (high of 94 °F (34 °C)) and water was scarce, causing many men to nearly faint from their exertions. During the night the Confederates slept within 600 yards (550 m) of the Union works, and Van Dorn readjusted his lines for the attack the next day. He abandoned his sophisticated plans for double envelopments. Shelby Foote wrote, "His blood was up; it was Rosecrans he was after, and he was after him in the harshest, most straightforward way imaginable. Today he would depend not on deception to complete the destruction begun the day before, but on the rapid point-blank fire of his guns and the naked valor of his infantry."
Rosecrans's biographer, William M. Lamers, reported that Rosecrans was confident at the end of the first day of battle, saying "We've got them where we want them" and that some of the general's associates claimed that he was in "magnificent humor." Peter Cozzens, however, suggested that Rosecrans was "tired and bewildered, certain only he was badly outnumbered—at least three to one by his reckoning." Steven E. Woodworth, a historian specializing in the Western Theater of the American Civil War, portrayed Rosecrans's conduct in a negative light:
Rosecrans ... had not done well. He had failed to anticipate the enemy's action, put little more than half his troops into the battle, and called on his men to fight on ground they could not possibly hold. He had sent a series of confusing and unrealistic orders to his division commanders and had done nothing to coordinate their activities, while he personally remained safely back in Corinth. The movements of the army that day had had nothing to do with any plan of his to develop the enemy or make a fighting withdrawal. The troops and their officers had simply held on as best as they could.
October 4
At 4:30 a.m. on October 4, the Confederates opened up on the Union inner line of entrenchments with a six-gun battery, which kept up its bombardment until after sunrise. When the guns fell silent, the U.S. troops prepared themselves to resist an attack. But the attack was slow in coming. Van Dorn had directed Hébert to begin the engagement at daylight, and the artillery fire was merely preliminary to enable Hébert to get into position for the assault.
At 7 a.m., Hébert sent word to Van Dorn that he was too ill to lead his division, and Brig. Gen. Martin E. Green was ordered to assume command and advance at once. Nearly two hours more elapsed before Green moved to the attack, with four brigades in echelon, until he occupied a position in the woods north of town. There he formed in line, facing south, and made a charge on Battery Powell with the brigades of Gates and McLain (replacing Martin), while the brigades of Moore (replacing Green) and Colbert attacked Hamilton's line. The assault on the battery was successful, capturing the guns and scattering the troops from Illinois and Iowa. Hamilton repulsed the attack on his position and then sent a portion of his command to the assistance of Davies, who rallied his men, drove the Confederates out of the battery, and recaptured the guns.
