Quick questions on The Second United Front 1937-1945: HSC Modern History National Study China

By late 1936 Mao's CCP had reached Yan'an after the Long March. Chiang had moved Zhang Xueliang's Manchurian Northeastern Army (around 130,000 men) to Shaanxi to lead a Sixth Encirclement Campaign. Zhang's men resented fighting Communists rather than reclaiming their Japanese-occupied homeland. CCP propaganda (the "August First Declaration" of 1935) explicitly courted them.

The CCP and KMT signed the formal Second United Front agreement in September 1937 after war with Japan had begun.

Joint operations were limited. The Battle of Pingxingguan (25 September 1937), where Lin Biao's 115th Division ambushed a Japanese convoy in Shanxi and killed around 1,000 Japanese, was the showpiece of CCP-KMT military cooperation. CCP propaganda from 1945 onward used Pingxingguan to claim the CCP had been the main resistance force.

Most cooperation was political theatre. Both parties used the Front to compete for legitimacy with intellectuals, students, and overseas Chinese. The CCP's Yan'an became a destination for thousands of Chinese youth and Western journalists. KMT Chongqing was simultaneously the official wartime capital and the focus of corruption charges.

From 1939 Chiang tightened the screws. The KMT instituted an economic blockade of the Shaan-Gan-Ning Border Region from late 1939, with around 400,000 troops cordoning the area. The CCP responded with the "production movement" (1942 onward), including the Nanniwan reclamation project, to achieve self-sufficiency.

The New Fourth Army operated in central China south of the Yangtze. The KMT high command ordered it north of the Yellow River in 1940; the CCP delayed compliance. On 5 January 1941, KMT forces under General Gu Zhutong attacked the New Fourth Army headquarters column of around 9,000 men in southern Anhui. Fighting lasted until 13 January.

From 1942 to 1944 Mao consolidated his ideological control over the CCP through the "Yan'an Rectification Movement" (Zhengfeng). Studied texts included Mao's own writings ("Reform Our Study," "Oppose Stereotyped Party Writing"). The movement crushed Wang Ming's Comintern faction and Kang Sheng's secret-police operations against alleged spies escalated; perhaps several thousand were killed or driven to suicide.

The Second United Front formally lasted until the Japanese surrender. Real cooperation had ended at the New Fourth Army Incident. Marshall Mission talks (December 1945 to January 1947) tried to revive a national coalition after the war but failed.

Lyman Van Slyke (Enemies and Friends: The United Front in Chinese Communist History, 1967) is the standard analytical study.

From 1939 it was largely fictional; after January 1941 it was a formality.

First (1924-1927) was inside the KMT; Second (1937-1945) was a parallel alliance. First was destroyed by Chiang; Second was eroded by both sides and ended at the Japanese surrender.

Stalin's intervention saved Chiang's life in December 1936. Without that, the timeline of Chinese politics from 1936 onward is unrecognisable.
