U. S. Army Department of the Northwest records

A collection of approximately 6,000 items from 1861 to 1904, it consists of documents, ledger books, receipts, muster rolls, payrolls, correspondence and other military records. The material details the workings of the paymaster's office of the U.S. Army Department of the Northwest primarily for the period 1861 to 1865. Although there is material for virtually all Union states, the documents are fullest for regiments from Illinois, Missouri, and Wisconsin. The collection also contains a few papers concerning the life and business affairs of John Oscar Culver after the Civil War, particularly the period 1880 to 1900 while he was living in California.
