Collection: Histories of Illinois Civil War Regiments and Units

Histories of Illinois Civil War Regiments and Units

The following histories of Illinois Civil War regiments and units originate from the first eight volumes of the nine volume publication, Report of the Adjutant General of the State of Illinois (1900-1902). (The ninth volume lists units of the Black Hawk, Mexican and Spanish-American Wars as well as the War of 1812.) The histories, some written shortly after the war’s end, are the work of numerous authors throughout the intervening years. The 1886 version of the Adjutant General’s Report included regimental histories compiled by that office which had not previously been published. The final 1900-1902 republication of the report incorporated revisions and corrections to the histories.

It was one of the six regiments organized under the first call of the President, at the commencement of the war of the rebellion. Six companies – A, B, C, D, E and F – were from St. Clair county; G, I and K, from Madison, and H from Montgomery.

During that time the garrison at Cairo was composed of the 8th, 9th, 10th and 12th Infantry. The brigade at Cairo was composed of these regiments and the 7th and 11th Infantry, the latter being stationed at Bird’s Point, Mo., and the 7th a part of the time at Cairo, and a part of the time at Mound City. The brigade was commanded by General Prentiss. During the three months’ service the work of the solider was made up of fatigue duty, building barracks, clearing off parade grounds, building fort defenses and the redan earthwork where the Ohio River is wedded to the Mississippi, and which guarded the confluence of those rivers from the possible advance of rebel gunboats. The monotonous work of this period was...

History of the 8th Illinois Infantry

On the 25th day of April 1861, the Regiment was organized at Springfield, and mustered in for three months’ service. Richard J. Oglesby, of Decatur, was appointed Colonel. The regiment was immediately sent to Cairo. Companies A and D, in command of Capt. Isaac Pugh, were sent to Big Muddy river, to guard the railroad bridge, as there was danger of its destruction by rebel sympathizers, to prevent the transportation of troops and supplies. Relieved by other troops, these companies rejoined the regiment at Cairo. The regiment remained at Cairo during its term of service, when it was mustered out. July 25th, 1861, the regiment reorganized and was mustered in for three years service. It remained at Cairo until October 1861, when it was ordered to Bird’s Point, Mo. During this time it received a thorough drill, and attained a high state of discipline. With other troops it made expeditions to Cape Girardeau, Commerce, Bloomfield, and Norfolk, Mo., and Paducah and Blandville, Ky., and joined in the feint on Columbus, Ky., in January. The move to Bloomfield is fixed in the memory of the soldiers of the Eighth by the raid on the rebel Colonel Hunter’s well stocked farm, and the rapid return march from Bloomfield to Cape Girardeau. In November, the regiment constructed at Bird’s Point extensive and comfortable quarters for the winter. February 2d, 1862, it was...
