Final answer:
Bragg's Confederate forces were defeated in the Battle of Chattanooga, which took place from November 23-25, 1863, leading to a strategic Union victory.
Step-by-step explanation:
General Braxton Bragg's Confederate forces were defeated in the Battle of Chattanooga, also known as Stone's River, and were forced to withdraw to the South. The Battle of Chattanooga was a significant engagement in the American Civil War that took place from November 23-25, 1863. Bragg's army faced Union forces under the command of Major General Ulysses S. Grant. A Union victory at Chattanooga allowed General William Tecumseh Sherman to use the city as a strategic point for launching his infamous March to the Sea. This defeat was a turning point for the Confederacy as it lost not only a crucial city but also their stronghold over the western theater.
