The Battle of Carthage, Missouri, was the first full-scale land battle of the Civil War. Governor Claiborne Jackson's rebel Missouri State Guard made its way toward southwest Missouri near where Confederate volunteers collected in Arkansas, while Colonel Franz Sigel's Union force occupied Springfield with orders to intercept and block the rebels from reaching the Confederates. The two armies collided near Carthage on July 5, 1861. The battle lasted for ten hours, spread over several miles, and included six separate engagements before the Union army withdrew under the cover of darkness.
The New York Times
called it "the first serious conflict between the United States troops and the rebels." This book describes the events leading up to the battle, the battle itself, and the aftermath.
