Carthage's location at the confluence of the Caney Fork and Cumberland rivers made it an important shipping and steamboat port throughout the first half of the 19th century. The area was developed for tobacco and hemp crops, as well as blooded livestock. Goods were shipped downstream to Nashville. During the Civil War, Carthage became an important post in the Eastern Highland Rim area of Tennessee. Carthage was selected as part of the route Confederate General Braxton Bragg marched the Army of Mississippi through on his Confederate Heartland Offensive into Kentucky. Later on March 6, 1863, Union Brigadier General George Crook established a Union outpost in Carthage to serve as a base for his effort to clear out the considerable Confederate guerrilla insurgency from East Tennessee through Middle Tennessee.
