last day was stadium jumping where they rode a course of 12 jumps at a 14-mile per hour (22.5 km/h) gait. Argo, the only field artillery officer in this part of the competition, rode Honolulu Tom Boy in a remarkable performance without a fault at a jump during the stadium jumping—the only rider without a fault that day. The U.S. team led from the start and was described by the 1932 Field Artillery Journal as a "glorious achievement for our riders and horses," as they took the gold medal in the team competition. In the individual standings, Thomson took the silver for the U.S., Chamberlin finished fourth and Argo eighth. (taken from the Field Artillery Journal, Sept.-Oct. 1932). Note: At that time, Argo was assigned to 1st Field Artillery at Fort Sill, Okla. World War II to present By 1940, the Field Artillery School had permission to train its own fixed wing pilots as field artillery spotters. The Army Air Corps turned Post Field over to the FA School and the facility began to swarm with Grasshoppers and Bird Dogs (single-engine small spotter airplanes) – part of the Department of Air Training. (Cessna L-19/O-1 Bird Dog aircraft were not placed in military inventories until 1950.) What was originally a five-week course was expanded, and special primary flight schools for prospective field artillery pilots were set up at Pittsburg, Kansas, and Denton, Texas. After attending one of these primary schools, pilots went to Post Field for their advanced training, which included short field procedures and observer training. By the end of the war, 262 pilots and 2,262 mechanics were trained at Post Field. In 1942, Fort Sill held approximately 700 Japanese Americans interned by the Department of Justice – mostly non-citizen Issei who had been arrested as spies and fifth columnists, despite a lack of evidence supporting the charges against them. 350 of these internees were transfers from Fort Missoula, Montana. One of them, Kanesaburo Oshima, was killed by a guard when he suffered a mental break and attempted to escape on 12 May. In addition to the Japanese American inmates, Fort Sill held three German prisoners of war. Advancements in air defense artillery and radar systems during the Cold War made the slow-moving Grasshoppers and Bird Dogs easy targets – especially in forward areas. Because of this vulnerability, they were phased out during the Vietnam War. During that conflict, 469
