[1][2][3] In June 1920, Japan, which suffered a crushing defeat in the Battle of Fengwudong, launched the so-called 'Gando Region Bulyeong Seonin Scorched Land Plan (間島地方不逞鮮人剿討計劃)' for a large-scale 'subjugation' of the independence army and invaded Gando with the size estimated to be around 18,000.
[5][4] The Japanese army surrounded and attacked the Korean village, gathered all the men in one place and massacred them with guns or spears, and raped and killed the women on sight.
The 77 troops of the 3rd Battalion of the 15th Regiment of the 14th Division of the Japanese Army from the Maritime Province, entered Jangam-dong, located 25 ri north of Yongjeongchon, and gathered all the residents, the majority of whom were Christians, at a church and held a concentration camp.
They set up 28 Christians and used them as targets for rifle shooting practice, and in Uiran-gu, Yanji County, they massacred all the residents of about 30 households and killed four brothers.
This time, the Japanese soldiers got straw bales on the corpses, sprinkled oil on them, and set them on fire, burning them until they turned into charcoal and ashes.
[4] Also, on 19 October 1920, Japanese troops arrested Lee Yong-jeom, the chief of Bukjangpae Village in Hwaryong-hyeon, and farmers Jang Doo-hwan, Shin Guk-hyeon, and Kim Jong-min, and killed them in Pungdoryeong.
The Jiando detachment, which was left in the field and was organized on 31 December, focused on searching for independence movement forces and handling the problem of defectors in Yongjeongchon, Gukjaga, Baekcho-gu, Dudo-gu, and Uiran-gu.
