Records of the Services of Illinois Soldiers in the Black Hawk War, 1831-32, and in the Mexican War, 1846-8 by Isaac H. Elliot (pub. 1882), was compiled by volunteers for the Palo Alto Battlefield National Historical Park into this database. This is a database of almost 5,600 Illinois men who enlisted as volunteers for the Mexican War (1846-1848). The place of enlistment is listed by city, not county. The troops would organize and then travel to a designated city to be enlisted. Illinois in the Mexican War is available for search at ILGenWeb.
