Among Union Army regiments, the 33rd Illinois became known as the “brains” regiment because it contained so many teachers. “It was stated derisively that the men would not obey orders which were not absolutely correct in syntax and orthography and that men who were discharged from it for mental incapacity, at once secured positions as officers in other regiments.” Many of them came from Illinois State Normal University; of the 97 teachers and pupils on the university’s rolls in 1860-1861, 53 entered the army.
