In June 1948, Dongye decided to adopt the strategy of "long siege, political offensive, and economic struggle" against Changchun, and set up a siege command post, with Xiao Jinguang as commander, Xiao Hua as political commissar, and Xie Fang as chief of staff. The total number of troops involved in the siege reached 100,000, of which the main forces were the 6th column and the 12th column. The main forces of the Changchun garrison were the 7th Army and the 60th Army, and the 7th Army was expanded on the basis of the new 38th Division of the New First Army, with a total strength of about 30,000 troops, which was the concubine of old Chiang Kai-shek.
The 60th Army was a unit of the Dian Army, and most of the officers and men were Yunnan people, who were homesick and did not want to be shot by old Chiang Kai-shek. After the army's 184th Division commander Pan Shuoduan revolted in Haicheng, the 60th Army's morale was even more unstable. The commander of the Changchun garrison was the famous general Zheng Dongguo of the Nationalist Army, who had been following Lao Jiang after the first phase of Huangpu and was one of his closest generals. Because the city of Changchun was strong and the defenders had a certain combat effectiveness, if they attacked strongly, they would inevitably pay a great price of casualties, so Dongye adopted the method of long-term siege.
Zheng Dongguo had been in the battlefield for a long time, knew that the isolated city was difficult to defend, at the beginning of his term of office, he ordered the troops to find a way to purchase military food, but because the outside of the city had been blocked by the People's Liberation Army, the defenders could only grab grain in the homes of the people in the city, and many citizens were killed. In the end, the Changchun defenders stored a total of 1.5 million kilograms of military food, but for the 100,000 defenders, it was only a drop in the bucket. Soon after, the airport was lost, the air transport was cut off, and Changchun became an isolated city.
During this period, in order to solve the problem of food shortage, Zheng Dongguo sent troops out of the city many times to grab grain, but all of our siege troops fought back. By August, the 60th Army had run out of food and could only borrow from the New 7th Army. The New 7th Army has been stationed in Changchun for a long time and has a certain family foundation, but this unit looks down on the Miscellaneous 60Th Army, and only gives the 60th Army some soybeans and bean cakes from the feed they feed the horses, which makes the officers and men of the 60th Army very angry, and once wanted to find Zheng Dongguo theory.
At the end of September, Xiao Jinguang, commander of the siege, issued a "Letter to the Officers and Men Of the Besieged Chiang Kai-shek Army" by radio, pointing out three paths to the encircled Nationalist troops: The first way is to continue to resist stubbornly, and finally to die of starvation and illness, or to be annihilated when the city is destroyed; second, if you expect to break through to Shenyang, you will have to pass through many liberated areas on the road, and the main force of the Northeast Field Army and the vast number of turned peasants are waiting to annihilate you; the third road is to hold an anti-Chiang kai-shek uprising and take the bright road of revolution, so that when you reach the liberated areas, you can get land and work and study.
In addition, Xiao Jinguang also ordered people to make many "condolence bags", which in addition to containing propaganda materials, there are also steamed buns, flapjacks and some other daily necessities. After the bag was delivered to the front, let the defenders come and get it themselves. During the Mid-Autumn Festival, Xiao Jinguang also deliberately let people fill mooncakes in the condolence bag. In the condolence bag given to the officers and men of the 60th Army, the paper wrapped in mooncakes was written with the following poem: "The Moon is round during the Mid-Autumn Festival, leaving your parents in Yunnan." The surrender uprising returned to his hometown, abandoning the dark and casting the good boy. ”
The 60th Army was a unit of the Dian Army, and it was not a concubine of old Chiang Kai-shek. The Nationalist army has always paid attention to factions, and the Central Army has always looked down on miscellaneous troops. After the 60th Army was sent to the northeast battlefield, it was ostracized everywhere, sent to the front during the battle, stayed at the end when retreating, and if it was surrounded by the People's Liberation Army, there was no one to rescue it. After entering Changchun, he was harassed by the New 7th Army, and only gave some bean cakes to feed the horses. Under these circumstances, Zeng Zesheng heard Xiao Jinguang's "Letter to the Officers and Men Trapped and Defending Chiang Kai-shek's Army," and he very much agreed with Xiao Jinguang's analysis, believing that only an uprising was the only way out.
Zeng Zesheng then found the military headquarters with Bai Zhaoxue, the commander of the 182nd Division, and Long Yao, the commander of the provisional 21st Division, and revealed to them his idea of wanting to revolt. Long Yao immediately expressed his support: "Our Sixty Army, over the years, has suffered too much anger from the concubines, exclusion, discrimination, poor equipment, low treatment, sent to the death to fight the front, retreat as a cover, reward them to lead, over our back, such a nest of gas, I have long had enough, I support the uprising!" Bai Zhaoxue also agreed. On October 17, 1948, Zeng Zesheng led the 60th Army to revolt, ceded half of the city's defense area, and made an important contribution to the liberation of Changchun, and was awarded the rank of lieutenant general in 1955.
