Only one American soldier is known to have been killed, Private Stephen D. Little, 12th Infantry Regiment, and five others were wounded, but other accounts say as many as three Americans died. Francisco Rosales says that the Americans killed sixty Mexicans in total and wounded several more. In honor of Private Little, the War Department changed the name of Camp Nogales to Camp Stephen D. Little, a base that would harbor more that 10,000 men by 1916. The camp was located along what is now Western Avenue from Grand Avenue to Interstate 19. The next major incident between the Americans and Pancho Villa occurred on January 11, 1916. Villista forces stopped a train near San Ysabel, Chihuahua, removed seventeen American passengers by gunpoint and then shot them all. Only one man survived by faking death. He later crawled away from the site while the Villistas were busy "stripping and mutilating" the dead. The victims were mining engineers who worked for ASARCO, they had been invited to Mexico by President Carranza to reopen the Cusihuiriachic mines south of Chihuahua. Their bodies were later recovered by a "special train" and taken back to the United States. President Woodrow Wilson refused to intervene in Mexico on behalf of the massacre, however, on March 9, 1916, Pancho Villa attacked the town of Columbus, New Mexico, killing eighteen Americans and burning several buildings. After that Wilson ordered General Pershing to launch the Mexican Expedition, an attempt to capture or kill Pancho Villa.
