New Fourth Army incident

• 1. Introduction

  ›

  The New Fourth Army Incident, known in Chinese as the Wannan Incident, erupted in January 1941 and brought the fragile alliance between China's two great rival powers to a permanent breaking point. How could two armies supposedly fighting the same enemy end up in a battle that left thousands dead? That question has divided Chinese historians ever since, with the Republic of China and the People's Republic of China offering versions of events that are almost irreconcilable. What is undeniable is that a force of roughly 9,000 soldiers was surrounded by a Nationalist army nearly nine times its size in the mountains of southern Anhui province. The answers to what happened, and who bears responsibility, reveal how deeply the Chinese Civil War continued to simmer beneath the surface of a war that was supposed to have suspended it.

  During the Second Sino-Japanese War, the Chinese Communist Party and the Nationalist government of Chiang Kai-shek had agreed to set aside their conflict and form a United Front against Japan. In practice, that arrangement was always strained. In the fall of 1940, according to Nationalist accounts and the argument laid out in Gregor Benton's book New Fourth Army, Communist forces attacked Nationalist troops under Han Deqin. For PRC historians, the flashpoint came in December 1940, when Chiang Kai-shek issued an order demanding that both the Eighth Route Army and the New Fourth Army withdraw north of the old Yellow River track within a month. The Communists agreed only to move their forces in Southern Anhui, known as Wannan, to the northern bank of the Yangtze River. That partial compliance set the stage for what followed. Each side accused the other of acting in bad faith, and neither account fully erases the other's grievance.

• 3. The Ambush at Maolin

  ›

  On the 4th of January 1941, a column of around 9,000 soldiers set out from Yunling Township in Jing County, moving toward Jiangsu along three planned routes. The army's ranks included not only combat troops but also civilian workers who staffed its political headquarters. On January 5, Nationalist forces numbering approximately 80,000, commanded by Shangguan Yunxiang, surrounded the column in Maolin Township. Days of fighting followed, and the sheer weight of numbers ground down the smaller force. Civilian workers caught inside the perimeter suffered heavy losses alongside the soldiers. On the 13th of January, New Fourth Army commander Ye Ting made a desperate decision: he would walk into Shangguan Yunxiang's headquarters himself and try to negotiate terms. The moment he arrived, he was detained. Political commissar Xiang Ying was killed in the fighting. Only around 2,000 people managed to break out of the encirclement, led by Huang Huoxing and Fu Qiutao.

  Chiang Kai-shek moved quickly to formalize the defeat. On the 17th of January, he ordered the New Fourth Army officially disbanded and sent Ye Ting to face a military tribunal. The Communist Party in Yan'an answered just three days later, on January 20, by ordering the army reorganized rather than dissolved. Chen Yi was named the new army commander. Liu Shaoqi became political commissar. The reconstituted force set up its general headquarters in Jiangsu, which now served as the combined command center for both the New Fourth Army and the Eighth Route Army. That combined force comprised seven divisions and one independent brigade, totalling more than 90,000 troops. Chiang's order to disband had, in effect, produced a larger and more consolidated Communist military structure north of the Yangtze River.

• 5. Memory and Meaning

  The incident cost the Communist Party its footholds south of the Yangtze River. In the CCP's telling, that territorial loss was offset by a gain in popular support, as the ambush and the killing of Xiang Ying allowed the party to cast itself as victims of Nationalist treachery and as the true vanguard fighting Japan. The Nationalist account framed the same events as justified punishment for repeated Communist provocations and insubordination. Both narratives hardened over the decades and remain the official positions of the ROC and PRC today. The incident entered Chinese literature as well: the novelist Mao Dun wrote a story called Fushi directly about these events, preserving the episode in the country's literary record alongside its contested political one.
