In August 1940, the Red Army initiated the Hundred Regiments Campaign, in which 400,000 troops attacked the Japanese simultaneously in five provinces. It was a military success that resulted in the death of 20,000 Japanese, the disruption of railways and the loss of a coal mine.
In August, Chinese communists launched an offensive in Central China. The Hundred Regiments Offensive took place between 20 August to 5 December 1941, was a major campaign of the Communist Party of China's National Revolutionary Army divisions commanded by Peng Dehuai against the Imperial Japanese Army in Central China. The battle had long been the focus of propaganda in the history of Chinese Communist Party but had become Peng Dehuai's "crime" during the Cultural Revolution. Certain issues regarding its launching and consequences are still controversial.
