Sheridan recommended Dye for the position as Chief Military Adviser to the Korean Government under King Gojong. He served the king for the next 11 years, even writing a military treatise in Korean. When he was in Korea, the assassination of Empress Myeongseong occurred. He received a report from Lee Hak-gyun; however, it was too late. He returned to the United States in 1899 but died the same year in Muskegon, Michigan.
