King, John N.
Raised in Sangamon County, Illinois, John N. King served in the Mexican War, though not in a military capacity. After the war, he returned to Sangamon County and sought an appointment to the U.S. Military Academy, for which he secured a recommendation from Abraham Lincoln. Failing to gain admission to the academy because he was too old, King engaged in government service in the far west, conducting surveys for the U.S. Army. When the Civil War began, King sought an officers' commission in the Army, travelling in the fall of 1861 from the West Coast to Washington, DC, hoping to secure an appointment. Unable to get a commission in the regular army, King still took an active role in Union military operations, serving on General John G. Parke's staff during the Roanoke Expedition. In February 1862, he received a captain's commission in the volunteers. He participated in the battles of South Mountain and Antietam. Unhappy with his status and duties, King tendered his resignation and left the army for the west, settling in the Washington Territory by February 1863. By December 1863, he had returned to the army and was stationed in Washington, DC. On July 6, 1865, he received brevet to major for efficient and meritorious service. He mustered out of the service on July 7.
