Overview
The Battle of Missionary Ridge was fought near Chattanooga, Tennessee, on November 25, 1863, during the Chattanooga Campaign. General Ulysses S. Grant commanded Union forces, while General Braxton Bragg commanded the Confederate Army of Tennessee.
After defeating General William S. Rosecrans at the Battle of Chickamauga, Bragg occupied the high ground around Chattanooga and started the Siege of Chattanooga. Union Officials responded by sending reinforcements under General Joseph Hooker and General William T. Sherman. They also placed Grant in command of Union forces near Chattanooga and replaced Rosecrans with General George Thomas as Commander of the Army of the Cumberland.
Grant improved the Union supply situation by opening the “Cracker Line.” Meanwhile, Bragg weakened his army by sending 15,000 soldiers under General James Longstreet toward Knoxville. Union forces captured Orchard Knob on November 23 and attacked Lookout Mountain on November 24.
On November 25, Grant ordered Sherman to attack the Confederate right, while Hooker threatened the left. Strong Confederate resistance slowed Sherman. Grant then ordered Thomas to capture the rifle pits at the bottom of Missionary Ridge. Thomas’ troops seized the pits but continued up the ridge without orders. They drove the Confederates from their positions and forced Bragg to retreat toward Dalton, Georgia. The Union victory ended the Siege of Chattanooga and secured the city as a supply center for Sherman’s Atlanta Campaign in 1864.

Significance
The Battle of Missionary Ridge is important to American History because it ended the Siege of Chattanooga, allowing the Union army to break out from the city. Soldiers from the Army of the Cumberland captured Confederate rifle pits at the bottom of Missionary Ridge and continued their advance, driving the Confederates from their defensive positions. The victory gave Union forces uncontested control of Chattanooga, which was known as the “Gateway to the Lower South.” Chattanooga then became an important supply center for General William T. Sherman’s Atlanta Campaign in 1864.
History
Rosecrans Moves Toward Chattanooga
On December 26, 1862, Major General William S. Rosecrans led the Union Army of the Cumberland out of Nashville, Tennessee, with orders to capture Chattanooga, Tennessee. Chattanooga was an important railroad junction that connected the upper Confederacy with the Deep South. Between Rosecrans and Chattanooga was Lieutenant General Braxton Bragg and his Confederate Army of Tennessee.
Bragg Abandons Chattanooga
The two armies clashed in a series of battles over the next nine months, and Confederates consistently retreated south. On September 9, Bragg abandoned Chattanooga and led the Army of Tennessee through the mountains into northern Georgia.
Bragg Stuns Rosecrans at Chickamauga
Although Rosecrans achieved his goal of capturing Chattanooga, he pursued Bragg’s army into Georgia. Stung by criticism that he received for abandoning Chattanooga, Bragg counterattacked at the Battle of Chickamauga (September 19–20, 1863).
Bragg Invests Chattanooga
The victorious Confederates drove the Federals back toward Chattanooga, forcing them to occupy the defensive works previously constructed by the Confederates. Bragg seized the high ground overlooking Chattanooga (Lookout Mountain, Seminary Ridge, and Raccoon Mountain) and laid siege to the city.
Changes in Federal Leadership
Reacting to the Army of the Cumberland’s dire situation, Northern authorities sent 20,000 soldiers commanded by General Joseph Hooker and 16,000 men led by Major General William T. Sherman to help lift the siege. Officials placed General Ulysses S. Grant in command of all Northern soldiers near Chattanooga and also replaced Rosecrans with General George Thomas as the commander of the Army of the Cumberland.
Cracker Line
As reinforcements arrived in late October 1863, Grant launched an operation to ease the Army of the Cumberland’s supply problems. By October 28, Grant’s men opened a narrow supply line known as the “Cracker Line,” and provisions started flowing into Chattanooga.
Longstreet Departs for Knoxville
On November 4, 1863, Bragg detached 15,000 soldiers from his army and sent them to East Tennessee under the command of Lieutenant General James Longstreet. Longstreet’s task was to dislodge Major General Ambrose Burnside and the Union Army of the Ohio from Knoxville and prevent him from reinforcing Grant at Chattanooga. Longstreet’s departure weakened Bragg’s forces investing Chattanooga.
Grant Plans to Take the Offensive
Following the opening of the Cracker Line, Grant began planning an assault on the Confederate forces. He intended to wait until Sherman’s men reached Chattanooga. Sherman’s men began arriving on November 20, but most of his force showed up later. On November 23, rumors circulated through Northern lines that the Confederate forces were retreating. Grant ordered General Thomas to reconnoiter the center of the Confederate line at the base of Missionary Ridge to determine Bragg’s intentions.
Battle of Orchard Knob
Early in the afternoon, 14,000 Northern forces under Brigadier General Thomas J. Wood easily overpowered the 634 Confederates at the Battle of Orchard Knob. Initially, Grant had directed the men to return to Northern lines, but upon seeing the ease the Union men had in securing the position, he ordered his soldiers to hold the position and to entrench.
Lookout Mountain — the Battle Above the Clouds
Union forces continued their assault on the Confederate position the next day. On November 24, General Hooker’s men attacked Confederate forces on Lookout Mountain, on the Southerners’ left flank. By mid-afternoon, the Union assault had stalled, primarily because a dense fog enveloped the mountain. The thick fog prompted soldiers later to nickname the Battle of Lookout Mountain as the Battle Above the Clouds. Although Hooker’s men did not take the mountain, he correctly predicted that Southern forces would withdraw from the mountain that night.
November 25, 1863 — Clash on Missionary Ridge
Bragg concentrated his Confederate soldiers on Missionary Ridge. On November 25, Grant ordered an attack. Sherman, who still did not have his entire force on the battlefield, was to attack the Confederate right flank, while Hooker was to demonstrate against the left flank. Thomas, who faced the center of the Confederate line, was to assist Sherman’s attack.
Thomas Captures Missionary Ridge
Unfortunately for Grant, stiff Confederate resistance slowed Sherman’s progress. Late in the afternoon, Grant ordered Thomas to move against the Confederate center and capture the Confederate rifle pits at the bottom of Missionary Ridge. Thomas’ men advanced and seized the rifle pits, but they did not halt as ordered. Instead, they forged ahead and drove the Confederates from Missionary Ridge. The unauthorized assault forced Bragg to retreat, ending the battle for Chattanooga.
Outcome
After abandoning Missionary Ridge, Bragg marched his army south toward Dalton, Georgia. Sherman and Hooker pursued briefly, but Grant soon ordered a halt, not wanting his forces to get too far removed from their supply lines.
The Battle of Missionary Ridge was costly for both sides. The Union suffered nearly 6,000 casualties (killed, wounded, and captured/missing), while the Confederacy lost over 6,500 men.
As Northern soldiers buried the Confederate dead, a chaplain asked Thomas if they should bury the Confederates in groups according to their respective states. Thomas responded, “Mix ’em up. I’m tired of States’ rights.”
Although costly, the price of victory was worth it for the North because it completed the federal breakout from Chattanooga. The Yankees’ uncontested control of Chattanooga, the “Gateway to the Lower South,” established the city as an important supply center for Sherman’s Atlanta Campaign in 1864.
