President Sacasa, under political pressure from José María Moncada, who had been the leader of a rebel faction which later joined the government after U.S. mediation efforts, appointed Anastasio Somoza García as Chief Director of the National Guard in 1925. Besides being a nephew of Sacasa, Somoza Garcia was a trusted friend of Moncada and a supporter of the liberal revolt. He was trusted by the Americans due to his service as a translator to Henry Stimson during the 1927 peace conference, schooling in the U.S., and training under the U.S. Marines (apparently, as an officer in the National Guard).
