The Battle of Marion was an action that occurred on December 17–18, 1864, during the American Civil War. The fight took place in southwestern Virginia's Smyth County near Marion. A Union Army under the command of Major General George Stoneman defeated a smaller Confederate Army under the command of Major General John C. Breckinridge. The fight was mostly a stalemate for about 36 hours as the Confederate troops held better field position. After realizing that his force was nearly surrounded and low on ammunition, Breckinridge stealthily withdrew his troops during the night, escaping to the south before heading east.
