The Battle of Hartsville was fought on December 7, 1862, in northern Tennessee at the opening of the Stones River Campaign the American Civil War.
Guarding the river crossing at Hartsville was the 39th Brigade, XIV Corps, Army of the Cumberland, consisting of the 106th Ohio Infantry, 108th Ohio Infantry, 104th Illinois Infantry, and 2nd Indiana Cavalry. The brigade was commanded by Col. Absalom B. Moore. Under the cover of darkness, Morgan crossed the river in the early morning of December 7, 1862, with about 1,300 men, mainly Kentuckians, outnumbered by about 1,000 troops by the Union brigade. Another Union force, three times that size, was encamped nine miles away at Castalian Springs, close enough to hear the guns, but too far away to take part.
Morgan's attack took the Union camp by surprise. One account indicates that the Confederates were able to get past the picket line by wearing blue uniforms, while another says they wore civilian clothes and posed as refugees. The attack began at 6:45 a.m. with a simultaneous artillery bombardment and an infantry attack, while the cavalry struck the flanks and rear. One of Moore's units broke and ran after an hour, which caused confusion and helped force the Federals to fall back. By 8:30 a.m., the Confederates had surrounded the Union soldiers, convincing Col. Moore to surrender.
