On the night of 30 October 1968, 120 members of a
Special Battalion of the
Korean People's Army landed at 8 separate locations between
Ulchin and
Samcheok in
Gangwon Province and moved inland on a 30-day mission to create guerilla bases in the
Taebaek Mountains. On the morning of 31 October, they entered several villages and began indoctrinating the villagers, several of whom slipped away to alert the authorities.
Republic of Korea Army forces soon arrived in the area and began hunting down the infiltrators. On the night of 9 December several North Korean commandos burst into the Lee household demanding food and shelter. The North Koreans asked Lee Seung-bok if he preferred North Korea or South Korea. When he replied that he preferred South Korea, the North Koreans began to beat him. Lee then said "I hate Communists," which enraged the North Koreans who proceeded to kill Lee, his mother Joo Dae-ha (33), younger brother Lee Seung-su (7) and younger sister Lee Seung-Ja (4). Lee's father Lee Seok-woo and older brother Lee Hak-gwan managed to escape from the house and raise the alarm. The North Koreans proceeded to mutilate Lee Seung-bok's face by giving him a half
Glasgow smile. The perpetrators fled the house and were never identified, but they may have been among the 113 members of the Special Battalion killed by South Korean forces. After his death, as part of the government's anti-communist education, the incident was included in
Moral textbooks for elementary schools accompanied with a blurred picture of the body. His statue was erected in elementary schools across South Korea, and there were mandatory school trips to the Lee Seung-bok Memorial Center in
Pyeongchang. In 1982, he was posthumously awarded the
Order of Civil Merit by then-President
Chun Doo-hwan. Beginning from the 1990s, as the government changed its education objectives, his statues were gradually removed from most of the schools, and paragraphs about the incident were reduced in the textbook until it was completely removed in 1995. ==Conspiracy theory==
