Several communities in Navarro County organized military units that saw action in the Civil War. Company E of the 15th Texas Infantry was formed on April 16, 1862, when two squads were combined into one unit under the leadership of Captain Joshua Long Halbert, a prominent Corsicana lawyer. Company G, 15th Texas Infantry, was originally part of William Melton's 13th Texas Infantry, but the company was reorganized during the winter of 1861-1862 as Company G, under the command of Captain Clinton Fouty. The two companies were assigned to Colonel William Speight, and saw action throughout the Trans-Mississippi region, including Arkansas, Texas, Louisiana and Indian Territory. As they began their journey to Arkansas, the regiment first saw combat on September 29, 1863 at the Battle of Bayou Fordoche, northeast of Baton Rouge, Louisiana. After the battle, the 15th Texas saw action at Bayou Bourbeau, which was one of the early skirmishes that led to the Red River Campaign. Although a Confederate victory, the battle took a toll on the soldiers from Navarro County, with 7 killed in action, 22 wounded and 5 missing. Additionally, the group later saw action during the Red River Campaign at the battles of Mansfield, Pleasant Hill, Mansura and Yellow Bayou, Louisiana. The campaign resulted in the halting of the Union advance by the Confederate forces, and may have prolonged the war by distracting the Union's efforts to capture Mobile, Alabama. The men of Companies E and G started their journey back to Navarro County on February 20, 1865 and were discharged later that spring.
