The Ulchin-Samcheok landings was an unsuccessful attempt by North Korea to establish guerrilla camps in the Taebaek Mountains on October 30, 1968, in order to topple Park Chung-hee's regime and bring about the reunification of Korea. As the DMZ became increasingly harder to penetrate after the Blue House Raid, Kim Il-sung deployed 120 North Korean commandos along eight separate coastal locations between Ulchin and Samcheok in Gangwon province on an important mission to indoctrinate South Korean citizens, which ended in failure.
