The Second Major Battle of the Civil War
Wilson's Creek was the first major Civil War battle fought west of the Mississippi River, and the scene of the death of Nathaniel Lyon, the first Union general killed in combat. The bloody Southern victory on August 10, 1861, focused greater national attention on the war in Missouri. The nearly pristine landscape allows visitors to experience one of the best-preserved battlefields in the nation. - NPS
