At the outbreak of the Black Hawk War, Lincoln volunteered for the Illinois state militia. On April 21, 1832, Lincoln and other men from the New Salem area were mustered into a company in the 4th Regiment of Illinois Mounted Volunteers, and the members of the company elected Lincoln as their captain. When his month of service ended, Lincoln re-enlisted twice, for twenty and thirty days respectively, serving as a private both times. He was discharged finally on July 10, 1832.
