The Hundred Regiments Offensive or the Hundred Regiments Campaign (Chinese: 百團大戰) (20 August – 5 December 1940) was a major campaign of the Chinese Communist Party's National Revolutionary Army divisions. It was 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.
