Hundred Regiments Offensive

Significance

The Hundred Regiments Offensive, launched on 20 August 1940 and extending to 24 January 1941, represented the largest and most sustained offensive operation mounted by the Eighth Route Army in Japanese-occupied North China since the start of the War of Resistance. Organized around 105 regiments and roughly 200,000 troops, the campaign targeted the Shijiazhuang–Taiyuan railway and several key transportation corridors under Japanese control, striking directly at the logistical and communications infrastructure sustaining the occupation. Operating across three distinct periods, the offensive inflicted over 12,000 casualties on Japanese forces and dealt a significant blow to Japan's 'prison cage policy,' a strategy designed to contain and strangle Communist-held base areas through interlocking blockhouses and road networks. Beyond its operational impact, the campaign elevated national morale and demonstrated that the Chinese Communist Party and the Eighth Route Army could conduct large-scale coordinated offensives, reinforcing their standing as a central military force in the broader Second Sino-Japanese War.
