On December 15th, 1864, the once powerful Confederate army in Tennessee was almost destroyed when a Union Battalion led by General George Thomas had swarmed the city of Nashville, Tennessee. This was one of two battles in Tennessee only 15 days apart from each other. The Confederate army suffered over 6,000 men killed/wounded, while the Union army suffered only a bit over 3,000 men killed/wounded. After the battle of Nashville, the Confederate army retreated back to Mississippi.
