Minnesota contributed the first state to offer troops to the Union in 1861 to the Civil War. The 1st Minnesota’s suicidal charge at Gettysburg on the second day saved the Union line at a cost of some 82 percent casualties — even as the U.S.–Dakota War of 1862 raged on the state’s own frontier.
The regiments and the record
Each regiment kept muster rolls, and after the war the state published its rolls of service — for Minnesota, the Minnesota Adjutant General’s reports and Board of Commissioners records. 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.
