After remaining inactive for two months after the Battle of Stones River, Rosecrans finally made a movement, sending a brigade under Col. John Coburn towards Columbia, Tennessee. Coburn, encountering a small Confederate force on March 5, 150 years ago today, attacked but was driven back. Then suddenly he was struck by the Confederates. He had encountered a Confederate cavalry corps under Major General Earl Van Dorn which was moving north on a foray. Van Dorn sent one division forward in a frontal attack, while Nathan Bedford Forest moved around Coburn's left flank into his rear. Coburn was driven off the hill where he had established his defense, while Forrest captured his wagon train. Surrounded and out of ammunition, Coburn surrendered with 1,500 of his troops. The Confederates lost only 350.
