This database includes muster-in and muster-out rolls for the four Minnesota regiments that served in the Spanish-American War: the 12th, 13th, 14th, and 15th regiments. Some field returns and casualty reports are also included. These records do not necessarily list every man in a unit. Often they include officers, men who are absent, and other changes in status. Details listed can include name, date, rank, place, residence, regiment, and death date where applicable, depending on the form.
