The Mississippi 31st Infantry Regiment was organized in March, 1862, using the 6th (Orr's) Mississippi Infantry Battalion as its nucleus. The unit served in Rust's, L. Hebert's, and Featherston's Brigade, Department of Mississippi and East Louisiana. It was part of the garrison at Vicksburg, then fought at Baton Rouge and Jackson. Later it continued the fight under General Featherson in the Army of Tennessee. The 31st was active throughout the Atlanta Campaign, endured Hood's winter operations in Tennessee, and saw action in North Carolina. It lost 10 killed and 37 wounded at Baton Rouge, and of the 215 engaged at Peach Tree Creek, seventy-six percent were disabled. In December, 1864, there were 86 men present for duty, and only a handful surrendered in April, 1865.
