History of the Twelfth Infantry[1][edit]

The Twelfth Infantry Illinois Volunteers was mustered into the United States service for three years August 1, 1861. The regiment remained at Cairo, where it was organized until September 5, 1861, when, with the Ninth Illinois Infantry, it moved up to and occupied Paducah, being the first Union troops there.

With the exception of occasional expeditions, the Twelfth lay at Paducah until February 5, 1862. Four companies, however, occupied Smithland, Kentucky, until January 25, 1862-Lieutenant Colonel Chetlain commanding Post. Were engaged in the demonstration against Columbus, Kentucky, forty-six miles from Paducah, during the Belmont battle. In January were engaged in a reconnaissance in force towards Fort Donelson, Tennessee.

February 5, Embarked for Fort Henry; moved up left bank and occupied Fort Heiman. Remained at Fort Heiman until February 12, when proceeded to Fort Donelson.

Endured the cold and snow and hunger and fatigue of the Fort Donelson battle; formed with the Ninth and Forty-first Illinois, McArthur's Brigade, which suffered so terribly, but fought so nobly on February 15. Loss, 19 killed, 58 wounded, and 10 missing.

February 22, moved to Clarksville, Tennessee, and occupied Fort Sevier. February 26, moved to Nashville. Returned to Clarksville, March 1. Mar 6 embarked for Pittsburg Landing. Went into camp 19th.

Took part in the terrible battle of Shiloh, being engaged nearly all the time of the two days. Colonel Chetlain commanded the regiment the 6th, but he being injured by a fall from his horse, Major Hugunin commanded on the 7th. Regimental loss, 109 killed and wounded, and seven missing.

April 28, moved with the army on Corinth; was engaged in the siege of Corinth, doing its share of picket and fatigue duty, extending saps, etc. After the evacuation the regiment was sent with General Pope in pursuit of the enemy. Lay at Booneville six days and then returned to Corinth. The regiment remained at Corinth until the middle of September. During the approach on Corinth were in Second Brigade, Second Division Army of Tennessee. Brigadier General Thomas A. Davies, commanding division; Brigadier General R. J.

October 3 and 4, were engaged in battle of Corinth. The division (second) Gen. Davies, and the sixth division, General McArthur, fought nearly the whole rebel army. The losses were very heavy, and the fighting most desperate. On the 4th, "Powell's Battery," which we were supporting, was captured by the enemy in a charge, but was almost immediately retaken. In this affair the Twelfth took a very conspicuous and brilliant part. Supported by a small part of the Fiftieth and Fifty-second Illinois Infantry, they drove the enemy from the works, capturing a stand of colors, and turned the guns of the battery on the enemy. The division lost more than half of the men that were lost during the day, the regiment losing 17 killed, 80 wounded, and 15 missing. Captain Guy C.
