Overview
The 133rd Indiana Infantry (One Hundred Days’ Service) was an infantry regiment organized in Indiana for Union service during the American Civil War. Mustered in May 17, 1864, this regiment was part of Indiana’s contribution to the Federal call for one hundred days’ troops. The regiment’s companies were primarily raised in the 7th Congressional district, with one company from Richmond in the 5th district. The 133rd Indiana Infantry served in the Western Theater, primarily in Tennessee, and was mustered out in August 1864.
This regiment was one of eight Indiana regiments raised for one hundred days’ service, intended to perform garrison and guard duties, thereby freeing veteran troops for active campaigning during the critical summer of 1864.
Organization & Service
The 133rd Indiana Infantry (One Hundred Days’ Service) was organized in May 1864 and mustered into Federal service on May 17, 1864. The regiment consisted of nine companies from the 7th Congressional district and one company from Richmond in the 5th district, totaling 941 men. Immediately after mustering, the regiment departed Indiana for Tennessee.
Upon arrival in Nashville, the 133rd Indiana was assigned to guard duty along key railroad lines, including the Nashville & Chattanooga, Tennessee & Alabama, and Memphis & Charleston railroads. The regiment’s primary responsibility was to protect these vital transportation routes, ensuring the safe movement of supplies and communications for Union forces, particularly those supporting General Sherman’s campaigns. The regiment remained engaged in this duty throughout its service, often operating beyond the original one hundred days’ enlistment term. The 133rd Indiana Infantry was mustered out in August 1864.
