notes.--Organized at
Cairo, Ill., and mustered in August 1, 1861, proceeding in the next month to
Paducah, Ky., where it remained until February, 1861, during which time it was engaged on occasional expeditions; also in the demonstration against
Columbus, and in a reconnoissance toward
Fort Donelson.
On the 5th of February it embarked for
Fort Henry, marching thence to
Fort Donelson, where it was engaged in the storming of the works; it lost in this, its first battle, 19 killed, 62 wounded, and 8 missing, out of 612 effective men. It was then in
General C. F. Smith's Division,

Lieutenant-Colonel Chetlain the regiment.
At

Tennessee.
The regiment remained at
Corinth during the eight months subsequent to that battle; then, on June 6, 1863, it moved to
Pocohontas, Tenn., where it guarded the railroad for a few months.
In January, 335 of the men reenlisted, and went home on the customary veteran furlough granted in such cases.
The Twelfth started on the
Atlanta campaign, May 9, 1864, having been assigned to
