[Q]: Passage: Un'yo was one of the ships dispatched to Kyushu in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yo in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident.
