陳立夫
During the Second Sino-Japanese War, the National Revolutionary Army was defeated in various battles by the Imperial Japanese Army. Chiang Kai-shek explained that "hanjian" espionage helped the Japanese and ordered CC Clique commander Chen Lifu to arrest the "hanjians". 4,000 were arrested in Shanghai and 2,000 in Nanjing. Because martial law was enforced, formal trials were not necessary, and the condemned were executed swiftly, while thousands of men, women and children watched with evident approval.
