1At the outbreak of the Black Hawk War, Abraham 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.
