A little further digging indicates this was likely the flag of the 1st and 4th consolidated regiment of Cockrell's First Missouri Brigade.

The regiment also participated in the Battle of Franklin on November 30, 1864. In Franklin, as at Allatoona, the 1st and 4th Missouri (Consolidated) was aligned as the second regiment from the left in Cockrell's brigade.[17] Cockrell's brigade reached the main Union line near a cotton gin, where the brigade ran into very heavy fire. Cockrell was wounded during the charge, and command of the brigade fell to Colonel Elijah Gates of the 1st and 3rd Missouri Cavalry (Consolidated), who was also wounded, but remained with the unit.[18]

The Confederates were able to break a hole in the Union line, but a strong counterattack drove the Confederates out of the main Union line.[19] The First Missouri Brigade was decimated at Franklin, suffering 419 losses out of the 696 engaged in a frontal assault on the fortified Union lines.[20] The 1st and 4th Missouri (Consolidated)'s commanding officer, Colonel Hugh A. Garland, was also killed in the charge. Garland had been carrying the regiment's flag when he fell; the flag was captured by Union troops. The regiment had entered the battle with around 100 men, and lost 35 of them killed, 25 wounded, and 2 missing, for a total of 62. The regiment, as well as the rest of the First Missouri Brigade, was on detached duty after Franklin, and missed the Battle of Nashville.[16]
