Iowa contributed more than 75,000 men — a remarkable share of its young population to the Civil War. Iowa sent famous fighting regiments to Shiloh, Vicksburg, and Atlanta, and produced generals like Grenville Dodge.
The regiments and the record
Each regiment kept muster rolls, and after the war the state published its rolls of service — for Iowa, the six-volume Roster and Record of Iowa Soldiers in the War of the Rebellion. 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.
