Its members were recruited in the counties of Weakley, McNairy, Haywood, Gibson, Madison, and Decatur. For a time the unit was stationed at Fort Pillow, then moved into Kentucky with Bragg. Later the 31st was assigned to General Stewart's, Strahl's, and Palmer's Brigade, and in December, 1862, consolidated with the 33rd Regiment. It participated in the campaigns of the Army of Tennessee from Murfreesboro to Atlanta, was part of Hood's operations, and fought in North Carolina.
