Overview
The 136th Indiana Infantry (One Hundred Days’ Service) was an infantry regiment organized at Indianapolis, Indiana, in May 1864 for service in the Union Army during the American Civil War. The regiment was part of Indiana’s quota of one hundred days’ troops, intended to provide short-term service in support roles, primarily in the Western Theater. The unit was mustered in on May 25, 1864, and was composed of companies raised from several congressional districts across the state. Its primary assignment was to relieve veteran troops by performing guard and garrison duties, thereby enabling experienced regiments to participate in major campaigns of 1864.
Organization & Service
The 136th Indiana Infantry (One Hundred Days’ Service) was organized at Indianapolis, with seven companies recruited from the 1st Congressional District and one each from the 3rd, 10th, and 11th districts. The regiment mustered into Federal service on May 25, 1864. Immediately after organization, the regiment was sent to Tennessee, where it was assigned to guard duty along critical railroad lines, including the Nashville & Chattanooga, Tennessee & Alabama, and Memphis & Charleston railroads. These assignments were vital for maintaining Union supply lines and communications, especially during the Atlanta Campaign.
The regiment’s service consisted largely of protecting railroad infrastructure, depots, and supply trains from Confederate raids and sabotage. The 136th Indiana Infantry remained engaged in these duties until the latter part of August 1864, serving slightly beyond its original term of enlistment. The regiment’s actions contributed to keeping General Sherman’s lines of communication open, ensuring the steady flow of supplies to Union forces operating in Georgia and the surrounding region. The regiment was mustered out at the end of its service term in late August 1864.
