The Tennessee 12th Infantry Regiment was organized at Jackson, Tennessee, in May, 1861. Its members were recruited in Dyer and Gibson counties, and Company E contained men from Kentucky. The unit was assigned to B.R. Johnson's, P.Smith's, Vaughan's, and Palmer's Brigade. During June, 1862, the Tennessee 22nd Infantry Regiment merged into the Tennessee 12th Infantry Regiment, and in October, 1862, this command was consolidated with the Tennessee 47th Infantry Regiment. It fought at Belmont, Shiloh , and Richmond, then joined the Army of Tennessee and served from Murfreesboro to Bentonville. This regiment was organized with 737 men, sustained 32 casualties at Richmond, and lost fifty-one percent of the 322 engaged at Murfreesboro. The 12th/47th had 87 disabled at Chickamauga and in December, 1863, totaled 373 men and 220 arms. It was included in the surrender on April 26, 1865.
