James D. Henry was a militia officer from the U.S. state of Illinois who rose to the rank of general during the Black Hawk War. Henry was born in Pennsylvania in 1797, and moved to Edwardsville, Illinois in 1822. In 1825, while living in Edwardsville, he was indicted with two other men for the murder of an acquaintance, though he never went to trial. One defendant was tried but found not guilty, and following the trial Henry moved to Springfield, Illinois, where he was elected sheriff. When the Winnebago War broke out in 1827 Henry acted as adjutant for four companies of volunteers.
