The Second Battle of Newtonia was fought on October 28, 1864, in Newton County, Missouri, as part of Major General Sterling Price's Missouri Expedition of the American Civil War. Price's Confederate cavalry force was in full retreat following its expedition into Missouri. On October 28, 1864, it stopped to rest about two miles (3 km) south of Newtonia, Missouri. About 3:00 p.m., Maj. Gen. James G. Blunt's Union cavalrymen spotted the rear of Price’s supply train entering the woods south of town on the Cassville road. McLain's Colorado Light Artillery, supported by the 15th Kansas Cavalry, opened on the rebels.
