The Second Battle of Lexington was a minor skirmish during the American Civil War, taking place on October 19, 1864, in Lexington, the county seat of Lafayette County, Missouri. It formed a part of Confederate Maj. Gen. Sterling Price's Missouri Expedition of that year, and led in turn to the Battle of Little Blue River two days later.Like the first Battle of Lexington, fought in September 1861, this engagement resulted in a Confederate victory. Its overall importance, however, was not nearly so marked as the first battle, which had cemented Southern control of the Missouri Valley and significantly raised Confederate morale in the region.
