Chattanooga, Tennessee, was a major rail center and a strategic vantage-point during the American Civil War, with high ground competed-for by both sides. When Union forces were besieged in the town, General Ulysses S. Grant forced a supply-route, earning him President Abraham Lincoln's gratitude.
Tennessee was the last state to join the Confederacy (June 1861), being deeply divided between the mountainous eastern zone, including Chattanooga, that was pro-Union, and the slave-intensive western counties that were pro-Confederate. [1] At one point, it was proposed that East Tennessee should become a separate state of the Union. [2]
When Tennessee seceded, future President Andrew Johnson was the only southern senator to remain in the senate, [3] putting his life at risk, but earning him credibility with Lincoln, who appointed him military governor of Tennessee in March 1862. [4] (The Confederacy retaliated by confiscating his land.) [5] As a Southern War Democrat, Johnson was the natural choice as Lincoln's running-mate in his successful 1864 re-election bid. [6]
Tennessee contributed more regiments to the Union than any other Confederate state did. [7] [8]
As an important railroad hub, connecting major southern arsenals, Chattanooga was closely engaged in the Confederate war effort from the start, despite local resistance and even some guerrilla activity. [9] The city remained in Confederate hands until September 1863, after which it was occupied continuously by the Union. General Rosecrans retreated to safety there following his catastrophic defeat at Chickamauga, besieged by General Braxton Bragg until General Ulysses S. Grant was able to open a supply line. Grant drove the Confederates off Lookout Mountain, before routing them decisively at Missionary Ridge. Chattanooga then served as the gateway to Georgia for General William T. Sherman's 1864 campaign.
A raid by Union Brig. Gen. James Negley aimed at capturing the Confederate-held city. His long artillery bombardment provoked a disorganized response from enemy gunners, but Negley withdrew on the second day. It had been a minor Confederate victory, but it demonstrated that the Union could strike deep into the enemy heartlands.
Diversionary tactic by Union Maj. Gen. William S. Rosecrans to distract the attention of Confederate General Braxton Bragg through extensive shelling from the north-east of the city, while Union troops were massing to the south-west. [10] When Bragg learned of this, he retreated into Georgia, and the Union occupied the city.
After its shock-defeat at Chickamauga (Georgia), Rosecrans’ Army of the Cumberland retreated into its fortifications at Chattanooga, where it was under heavy siege by Bragg and facing surrender. The demoralised Rosecrans was urgently reinforced by the team of Grant, Thomas and Sherman. [11] [12] Principal actions:
The Battle of Chickamauga, fought on September 18–20, 1863, between the United States Army and Confederate forces in the American Civil War, marked the end of a U.S. Army offensive, the Chickamauga Campaign, in southeastern Tennessee and northwestern Georgia. It was the first major battle of the war fought in Georgia and the most significant US defeat in the Western Theater, and it involved the second-highest number of casualties after the Battle of Gettysburg.
Braxton Bragg was an American army officer during the Second Seminole War and Mexican–American War and Confederate general in the Confederate Army during the American Civil War, serving in the Western Theater. His most important role was as commander of the Army of Mississippi, later renamed the Army of Tennessee, from June 1862 until December 1863.
The Battle of Lookout Mountain also known as the Battle Above the Clouds was fought November 24, 1863, as part of the Chattanooga Campaign of the American Civil War. Union forces under Maj. Gen. Joseph Hooker assaulted Lookout Mountain, Chattanooga, Tennessee, and defeated Confederate forces commanded by Maj. Gen. Carter L. Stevenson. Lookout Mountain was one engagement in the Chattanooga battles between Maj. Gen. Ulysses S. Grant's Military Division of the Mississippi and the Confederate Army of Tennessee, commanded by Gen. Braxton Bragg. It drove in the Confederate left flank and allowed Hooker's men to assist in the Battle of Missionary Ridge the following day, which routed Bragg's army, lifting the siege of Union forces in Chattanooga, and opening the gateway into the Deep South.
William Starke Rosecrans was an American inventor, coal-oil company executive, diplomat, politician, and U.S. Army officer. He gained fame for his role as a Union general during the American Civil War. He was the victor at prominent battles in the Western theater of the American Civil War. However, his military career ended after his disastrous defeat at the Battle of Chickamauga in 1863.
The Army of Tennessee was the principal Confederate army operating between the Appalachian Mountains and the Mississippi River during the American Civil War. Named for the State of Tennessee, It was formed in the same state in late 1862 and fought until the end of the war in 1865, participating in most of the significant battles in the Western Theater.
The Battle of Missionary Ridge, also known as the Battle of Chattanooga, was fought on November 25, 1863, as part of the Chattanooga campaign of the American Civil War. Following the Union victory in the Battle of Lookout Mountain on November 24, Union forces in the Military Division of the Mississippi under Maj. Gen. Ulysses S. Grant assaulted Missionary Ridge and defeated the Confederate Army of Tennessee, commanded by Gen. Braxton Bragg, forcing it to retreat to Georgia.
The Tullahoma campaign was a military operation conducted from June 24 to July 3, 1863, by the Union Army of the Cumberland under Maj. Gen. William Rosecrans, and is regarded as one of the most brilliant maneuvers of the American Civil War. Its effect was to drive the Confederates out of Middle Tennessee and to threaten the strategic city of Chattanooga.
The Battle of Wauhatchie was fought October 28–29, 1863, in Hamilton and Marion counties, Tennessee, and Dade County, Georgia, in the American Civil War. A Union force had seized Brown's Ferry on the Tennessee River, opening a supply line to the Union army in Chattanooga. Confederate forces attempted to dislodge the Union force defending the ferry and again close this supply line but were defeated. Wauhatchie was one of the few night battles of the Civil War.
The Chickamauga campaign of the American Civil War was a series of battles fought in northwestern Georgia from August 21 to September 20, 1863, between the Union Army of the Cumberland and Confederate Army of Tennessee. The campaign started successfully for Union commander William S. Rosecrans, with the Union army occupying the vital city of Chattanooga and forcing the Confederates to retreat into northern Georgia. But a Confederate attack at the Battle of Chickamauga forced Rosecrans to retreat back into Chattanooga and allowed the Confederates to lay siege to the Union forces.
The Battle of Davis's Cross Roads, was fought September 10–11, 1863, in northwestern Georgia, as part of the Chickamauga Campaign of the American Civil War. It was more of a series of maneuvers and skirmishes than an actual battle and casualties were negligible.
The Battle of Ringgold Gap was fought November 27, 1863, outside the town of Ringgold, Georgia, by the Confederate and Union armies during the American Civil War. Part of the Chattanooga Campaign, it followed a heavy Confederate loss at the Battle of Missionary Ridge from which General Braxton Bragg's artillery and wagon trains were forced to retreat south. The five hour Battle of Ringgold Gap resulted in the Confederate victory of Major General Patrick R. Cleburne and gave the Army of Tennessee safe passage to retreat through the Ringgold Gap mountain pass.
The western theater of the American Civil War encompassed major military operations in the states of Alabama, Georgia, Florida, Mississippi, North Carolina, Kentucky, South Carolina and Tennessee, as well as Louisiana east of the Mississippi River. Operations on the coasts of these states, except for Mobile Bay, are considered part of the Lower Seaboard Theater. Most other operations east of the Appalachian Mountains are part of the eastern theater. Operations west of the Mississippi River took place in the trans-Mississippi theater.
John Thomas Wilder was an officer in the Union Army during the American Civil War, noted principally for capturing the critical mountain pass of Hoover's Gap during the Tullahoma Campaign in Central Tennessee in June 1863. Wilder had personally ensured that his "Lightning Brigade" of mounted infantry was equipped with the new Spencer repeating rifle. However, Wilder initially had to appeal to his men to pay for these weapons themselves before the government agreed to carry the cost. The victory at Hoover's Gap was attributed largely to Wilder's persistence in procuring the new rifles, which disoriented the enemy.
The 17th Indiana Infantry Regiment, also known as 17th Indiana Mounted Infantry Regiment, was an infantry and mounted infantry regiment that served in the Union Army from 1863 to 1865 during the American Civil War. It served in West Virginia before being transferred to the Western Theater. In that theater, it was known for its membership in the "Lightning Brigade."
Wheeler's October 1863 Raid was a large cavalry raid in southeastern Tennessee during the American Civil War. Maj. Gen. Joseph Wheeler's Confederate cavalry scored a great initial success, but subsequently was roughed up by Union cavalry during its withdrawal south of the Tennessee River.
The Chattanooga campaign was a series of maneuvers and battles in October and November 1863, during the American Civil War. Following the defeat of Maj. Gen. William S. Rosecrans's Union Army of the Cumberland at the Battle of Chickamauga in September, the Confederate Army of Tennessee under Gen. Braxton Bragg besieged Rosecrans and his men by occupying key high terrain around Chattanooga, Tennessee. Maj. Gen. Ulysses S. Grant was given command of Union forces in the West which was now consolidated under the Division of the Mississippi. Significant reinforcements also began to arrive with him in Chattanooga from Mississippi and the Eastern Theater. On October 18, Grant removed Rosecrans from command of the Army of the Cumberland and replaced him with Major General George Henry Thomas.
The 10th Kentucky Infantry Regiment was a three-year volunteer infantry regiment that served in the U.S., or Union Army during the American Civil War.
The Battle of Brown's Ferry was an engagement of the American Civil War which took place on October 27, 1863, in Hamilton County, Tennessee. During the battle, two Union brigades drove Confederate sharpshooters from the Tennessee River, which allowed supplies to start arriving to the Union army at Chattanooga. Although a minor engagement, the battle proved to have significant results in paving the way for the Union victory at Chattanooga a month later.
The Lightning Brigade, also known as Wilder's Brigade or the Hatchet Brigade was a mounted infantry brigade from the American Civil War in the Union Army of the Cumberland from March 8, 1863, through November 1863. A novel unit for the U.S. Army, its regiments were nominally the 1st Brigade of Maj. Gen. Joseph J. Reynolds' 4th Division of Thomas' XIV Corps. Operationally, they were detached from the division and served as a mobile mounted infantry to support any of the army's corps. Colonel John T. Wilder was its commander. As initially organized, the brigade had the following regiments:
Henry Benedict Mattingly was a Union Army soldier in the American Civil War and a recipient of the United States military's highest decoration, the Medal of Honor, for his actions at the September 1, 1864, Battle of Jonesborough, Georgia.
