North Dakota contributed frontier companies of Dakota Territory to the Civil War. The Civil War reached Dakota Territory mainly as frontier defense in the wake of the 1862 Dakota War, with military posts guarding settlers and trails.
The regiments and the record
Each regiment kept muster rolls, and after the war the state published its rolls of service — for North Dakota, Dakota Territory military records at the State Historical Society of North Dakota. These are among the richest genealogical records of the nineteenth century, naming a soldier’s age, town, unit, and fate.
Pensions and the aftermath
Union veterans and their widows could apply for federal pensions, generating detailed files now at the National Archives, and many joined the Grand Army of the Republic. A veteran’s grave, pension file, and roster entry together can reconstruct his entire war.
