Abraham Lincoln in the Black Hawk War

Abraham Lincoln served as a volunteer in the Illinois Militia from April 21, 1832 to July 10, 1832, during the Black Hawk War. Lincoln never saw combat during his tour, but he was elected captain of his first company. He was also present in the aftermath of two of the war's battles, where he helped to bury the militia dead. He was mustered in and out of service during the war, going from captain to private and finishing his service in an independent spy company commanded by Captain Jacob Early.

Lincoln's service had a lasting impression on him, and he related tales about it later in life with modesty and humor. Through his service he forged lifelong political connections. In addition, he received a land grant from the U.S. government for his military service. Though Lincoln had no military experience when he assumed command of his company, he was generally regarded as an able and competent leader.
