Wisconsin contributed roughly 91,000 men to the Civil War. The 2nd, 6th, and 7th Wisconsin formed the core of the famous Iron Brigade, and the 8th carried Old Abe, a live eagle, into battle.
The regiments and the record
Each regiment kept muster rolls, and after the war the state published its rolls of service — for Wisconsin, the Wisconsin Adjutant General’s Roster of Wisconsin Volunteers. 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.
