Overview
The 145th Indiana Infantry (One Year’s Service) was an infantry regiment organized in Indiana for Union service during the American Civil War. The regiment was raised in the 3rd Congressional District in response to a call for one-year regiments in late 1864. It was mustered into Federal service at Indianapolis in February 1865 and served primarily in the Western Theater, performing guard and garrison duties in Georgia until early 1866.
This regiment served the Union cause during the final months of the war and the early period of postwar occupation in the South.
