The Battle of Carthage was the earliest full-scale battle of the Civil War, preceding Bull Run by 11 days. Battle of Carthage State Historic Site contains a quiet meadow and the spring that made the area an encampment for both the Union and Confederate troops during the battle. The area is little changed in its appearance since the battle was fought on July 5, 1861. A few minutes off of Interstate 44, the site interprets the battle that set the stage for a decisive showdown a month later at Wilson’s Creek.
