Hundred Regiments Offensive

• 1. The Cage Policy And The Summer Of 1940

  ›

  In the summer of 1940, Japanese forces in North China tightened their grip on anti-Japanese base regions through a strategy known as the prison cage policy. This system relied on railways, roads, and fortified positions to isolate and besiege Communist strongholds. From 1939 to 1940 alone, the Japanese conducted 109 extensive mopping-up operations involving over 1,000 troops each. These campaigns deployed more than 500,000 soldiers across the region, creating a critical threat to the survival of the Eighth Route Army's bases. At the same time, the broader situation in China was deteriorating rapidly. Forward battlefields suffered successive defeats while internal calls for peace with Japan grew louder within the Kuomintang government. Wang Jingwei had already defected to form a puppet regime, deepening national pessimism and confusion. A pervasive atmosphere of compromise enveloped both military units and civilian populations, severely undermining morale. The Eighth Route Army Headquarters recognized that a major strategic operation behind enemy lines was necessary to dismantle this blockade. They sought to enhance national resistance efforts and bolster public spirit during a period of profound adversity.

• 2. Secret Orders And The August Mobilization

  ›

  On the 22nd of July 1940, Zhu De, Peng Dehuai, and Zuo Quan jointly issued the Preliminary Battle Order outlining the campaign's objectives. Their directive explicitly stated the need to counter the prison cage policy and impede Japanese advances toward Xi'an. The order specified exploiting the concealment offered by tall summer millet crops and the rainy season to launch sabotage on the Shijiazhuang, Taiyuan railway. This directive mandated participation from at least 22 regiments drawn from the Jin-Cha-Ji Military Region, the 129th Division, and the 120th Division. On the 8th of August, the Eighth Route Army Headquarters released the Operational Battle Order clarifying strategic deployment across multiple fronts. The Jin-Cha-Ji Military Region would assault the eastern segment of the Zheng-Tai Railway while the 129th Division targeted the western section. The 120th Division received instructions to strike the northern segment of the Tongpu Railway and the Fen, Li Highway. All troops were ordered to commence combat operations on the 20th of August with success measured primarily by destruction inflicted on the Zheng-Tai Line. In a state of stringent confidentiality, diverse factions conducted comprehensive preparations before the campaign began. Reconnaissance teams deployed deep into regions adjacent to railways to chart Japanese stronghold locations and troop arrangements. Local military and civilian populations mobilized to accumulate grain, ammunition, and tools for sabotage work. Blacksmiths specifically organized to fabricate crowbars, pickaxes, and other essential equipment for rail destruction.

• 3. The Three Phases Of Combat

  On the night of August 20, the Eighth Route Army initiated a synchronized offensive spanning thousands of kilometers along the North China front. Gunfire and explosions abruptly resonated along the Shijiazhuang, Taiyuan Railway as signal flares illuminated the night sky. Forces from the Jin-Cha-Ji Military Region executed an offensive from three flanks: the right contingent seized Niangzi Pass and obliterated a railway bridge. The central contingent conducted an unexpected assault on the Jingxing coal mine collaborating with miners to dismantle mining infrastructure entirely. This action suspended operations for more than six months while the left contingent undermined the railway connecting Weishui and Shijiazhuang. During the intense confrontation at Jingxing, soldiers utilized doors and blankets to shield electric fences, sacrificing lives to provide passage for their army. Simultaneously, the 129th Division won swift victories along the western segment of the railway securing multiple stations including Lujiazhuang, Shanghu, and Mashou. The 14th Regiment secured the elevated position at Shinaoshan to facilitate sabotage operations successfully defending it against multiple assaults by Japanese forces from Yangquan. For six days these men subsisted on black beans, corn husks, and vegetable soup while repelling numerous attacks and eliminating over 400 adversaries. On the 21st of August the 8th Company of the 25th Regiment was ambushed at Daluopo Village where they engaged in hand-to-hand combat killing more than 40 Japanese soldiers including a platoon leader.

• 4. The Cost Of Destruction And Conflicting Records

  ›

  Internal records indicate that losses of the Japanese First Army in the first phase amounted to 199 killed including 9 officers and 283 wounded including 15 officers. One report claimed 4,880 abandoned enemy corpses and 263 captured soldiers while another source recorded different figures entirely. Two separate reports from the Eighth Army based on statistics before December 5 presented conflicting casualty numbers totaling either 21,338 or 46,000 combat successes. A 2010 article by Pan Zeqin suggested actual results should exceed 50,000 casualties. Japanese military records contain no total casualty figures but document 276 killed for the 4th Independent Mixed Brigade and 133 killed plus 31 missing for the 2nd Independent Mixed Brigade. Western sources recorded approximately 20,900 Japanese casualties and about 20,000 collaborator casualties. The Chinese also recorded 474 kilometers of railway and 1,502 kilometers of road sabotaged alongside 213 bridges and 11 tunnels blown up. Japanese records give significantly lower figures showing only 73 bridges, 3 tunnels, and 5 water towers destroyed with 20 stations burned. Damage to communication systems included 1,333 cable posts cut down and 1,107 turned over with up to 146 kilometers of cable severed. One mining site at Jingxing Coal Mine stopped operating for half a year while other infrastructure suffered varying degrees of destruction across North China.

• 5. The Political Fallout And Historical Debate

  ›

  Peng Dehuai and Mao Zedong had disagreed over confrontation tactics since at least the Luochuan Conference in August 1937. Mao remained concerned about Communist losses against well-equipped Japanese forces throughout their strategic disagreements. During the Great Leap Forward Peng's opposition to Mao's policies led to his downfall and later the launching of the Hundred Regiments Offensive became criminalized during the Cultural Revolution. In 1967 Red Guard groups issued leaflets claiming Peng launched the offensive without consulting Chairman Mao as an adventuristic impulse. These documents stated that mobilizing 105 regiments revealed too much force prematurely leading to terrible consequences. Peng was tried unfairly from the 1950s because he was charged with launching war without permission from the Central Military Committee. Zhang Xueqin noted this offensive should have been launched before 10 days on the 10th of August according to the Order of Military Preparation proving CMC awareness. Nie Rongzhen defended Peng by stating reports were sent to the top mentioning plans to strike and sabotage the Zhengtai Railway. He argued such sabotage was routine guerrilla work not a major strategic issue requiring committee approval. The consensus in China after the Cultural Revolution generally supports the battle despite earlier political controversies surrounding its execution.

• 6. Memorials And Modern Commemoration

  A memorial was erected in 1987 at the peak of Shinao Mountain in Yangquan Shanxi Province to commemorate this significant offensive. In 2010 a new edifice for the Hundred Regiments Offensive Memorial Hall was finalized containing historical artifacts and actual directives issued by Zhu De, Peng Dehuai, and Zuo Quan concerning railway destruction. During the 2015 China Victory Day Parade the Bayonet Combat Hero Company was recognized as part of the heroic unit formation perpetuating lasting memory of the campaign. On the afternoon of the 7th of July 2025 Xi Jinping visited Yangquan to lay a wreath honoring martyrs and tour the Memorial Hall. Relief sculptures stand within the hall displaying scenes from the conflict while extensive collections preserve documents and equipment used during operations. These memorials serve as enduring symbols of resistance against Japanese invasion and demonstrate considerable power of the anti-Japanese national united front promoted by the Chinese Communist Party. The site continues to attract visitors seeking to understand pivotal moments in the Second Sino-Japanese War through preserved history and official tributes.
