ILLINOIS - Federal    
You will notice cavalry and artillery companies listed within infantry regiments. Later in the war, these were transferred to all cavalry or artillery units. You will also see listed, units which originated in other states, but which fought under Illinois designations. Some units of Illinois men were recruited and assigned to other states, then officially transferred and re-named as Illinois regiments. Other units such as Busteed's Chicago Light Artillery apparently remained as part of the New York 1st Light Artillery and 4th Artillery for the remainder of the war.

Civil War common practice was utilized for Regiments with unknown nicknames, and the Colonel's name was plugged in temporarily. IE: 63 Mord's (Francis) Regiment.
