Decisive Encounters by Odd Arne Westad, published in 2003, is the only English book on the entire span of the Chinese Civil War, from post-WWII to Mao’s victory in 1950, to my knowledge.
Besides the military aspects, it also covers its effects on Chinese society.
The book starts with a vivid picture of the devastation wrought on innocent villagers of Sipang County, 400 miles northwest of Peking, in the first months of 1946.
As they began to plant their fields in the spring of 1946, after the Japanese invasion, the first battle was fought right at their doorstep by the army of Chiang Kai Shek against the CCP.
A year later, the communists came back and upturned the patterns of power and income through land reform. More fighting ensued in late 1947 when the GMD fought the CCP to reconquer the county.
And then, after the CCP had won and the villagers prepared for their first normal harvest in years, the authorities marched off a large group of young men to fight the Korean War.
It was a time of untold hardship and terror. Those who do not live in such times can pontificate on the virtues of free elections and democracy. What these villagers want was just peace and stability to live a normal, albeit harsh, life. (P 17)
