Following the Confederate retreat after the drawn Battle of Perryville in central Kentucky, the Confederate army moved through East Tennessee and turned northwest to defend Murfreesboro. General Braxton Bragg's veteran cavalry successfully harassed Union General William Rosecrans troop movements, capturing and destroying many of his supply trains. However, they could not completely prevent supplies and reinforcements from reaching Rosecrans. Despite the large number of casualties, the battle was inconclusive. It is usually considered a Union victory, since afterward General Bragg retreated south to Tullahoma. Even so, the Union army did not move against Bragg until six months later, in June 1863. The battle was significant since the Union gained a base from which it could push its eventual drive further south, which enabled its later advances against Chattanooga and Atlanta. The Union eventually divided the territory into the Eastern and Western theaters, followed by Sherman's March to the Sea through the South. The Stones River National Battlefield is now a national historical site.
