The 17th Regiment Illinois Volunteer Infantry was an infantry regiment that served in the Union Army during the American Civil War.
The 17th Illinois Infantry was organized at Peoria, Illinois, and mustered into Federal service at Peoria, Illinois, on May 24, 1861, for three years service.[1]
The 17th Illinois Volunteers fought at the bloody Battle of Shiloh in Hardin County, Tennessee, in April 1862, with 130 members of the regiment killed and wounded in the two-day battle. This unit also participated in the last phase of the 1863 Siege of Vicksburg in Warren County, Mississippi, a protracted battle which ultimately led to the surrender of over 29,000 Confederate troops.[2]
The regiment was mustered out of service on June 4, 1864, upon expiration of its term of enlistment and its recruits and veterans were transferred to the 8th Illinois.
The regiment suffered 3 officers and 71 enlisted men who were killed in action or who died of their wounds and 1 officer and 71 enlisted men who died of disease, for a total of 146 fatalities.[3]
