Overview
The 134th Indiana Infantry (One Hundred Days’ Service) was an infantry regiment organized at Indianapolis, Indiana, in May 1864 for Union service during the American Civil War. Composed of men primarily from the 4th and 5th Congressional districts, the regiment was mustered in for a term of one hundred days as part of Indiana’s quota of short-term volunteers. The unit served in the Western Theater, primarily in Tennessee, and was tasked with critical guard and garrison duties to support major Union operations in 1864.
This regiment is distinct from other Indiana infantry regiments with different service terms.
Organization & Service
The 134th Indiana Infantry (One Hundred Days’ Service) was organized at Indianapolis and mustered into service on May 25, 1864, with a total strength of approximately 950 men. Seven companies were recruited from the 4th Congressional district and three from the 5th. The regiment departed Indiana immediately after mustering and proceeded to Tennessee.
Upon arrival in Nashville, the 134th Indiana was assigned to guard duty along several key railroad lines, including the Nashville & Chattanooga, Tennessee & Alabama, and Memphis & Charleston railroads. The regiment’s primary responsibility was to protect these vital supply and communication routes, thereby enabling veteran Union troops to participate in active field campaigns, notably those under General Sherman. The 134th Indiana remained engaged in this duty throughout its service, operating beyond its original enlistment period to ensure the continued flow of supplies to Union forces. The regiment was mustered out in August 1864.
