Parts of the 33rd Army and the 34th Army were compiled by the Huaihai Uprising, so this one is mainly Huaihai.
In late September 1948, three days after the victory in the Battle of Jinan, Su Yu, acting commander and acting political commissar of the East China Field Army, proposed to the Central Military Commission of the Communist Party of China that he hoped to take advantage of the victory to attack and annihilate Huaiyin, Huai'an, and Haizhou, known as the Battle of Huaihai, with the main goal of annihilating Li Yannian's 9th Appeasement Zone, which was far away from Xuzhou, in preparation for the capture of Xuzhou.
The original idea of the Huaihai Campaign was actually "Little Huaihai", and Su Yu formulated a battle plan that would be: to use the Northern Jiangsu Corps to recover Lianghuai, to block the main force of Huaye to aid the enemy, and the second stage was to attack Haizhou (present-day Lianyungang) and completely liberate Northern Jiangsu.
Entrenched in Haizhou was Li Yannian's 9th Appeasement District, which only had Wang Zejun's 44th Army (150th Division and 162nd Division) under its jurisdiction, with a total strength of only more than 15,000 people, and its combat effectiveness was not strong.
This "little Huaihai" can open up the connection between Shandong and northern Jiangsu.
However, after the Battle of Jinan, in order to prevent Huaye from fully retaking Jiangbei, Gu stopped Huang Baitao's corps on the Longhai Line. Huang Baitao's 7th Corps (about 80,000 men of the 25th, 63rd, and 64th Armies) used the Longhai Line as a dividing line to separate the Shandong base area from the northern Jiangsu guerrilla zone.
Therefore, in the two stages of the original version of "Xiaohuaihai", a front-loading operation was added, that is, the first annihilation of Huang Baitao's corps.
Once Huang Baitao's corps was destroyed, Hua Ye could fully control northern Jiangsu, drink the Yangtze River, and cross the river from Shanghai and Nanjing, and the military pressure faced by the Kuomintang at that time could be imagined. It also formed a situation of encirclement of Xuzhou on the east, south, and north, which was very unfavorable to the overall situation of the Kuomintang.
On October 11, Mao Zedong sent a telegram to Huaye, confirming the idea of a three-stage Huaihai campaign, and at the same time the Central Plains Field Army should attack the Zhengxu Line and contain Sun Yuanliang's army to alleviate the pressure on Huaye to block reinforcements.
In October 1948, at the High Military Conference of Chiang Kai-shek's Army, the troops under the Xuzhou Suppression Command should abandon unnecessary cities and gather around Xuzhou. Sun Yuanliang abandoned Zhengzhou, Qiu Qingquan abandoned Shangqiu, Huang Baitao and Li Mi abandoned Xu Dong, and more than 400,000 people from 4 corps gathered near Xuzhou to prepare for a decisive battle with Huaye.
If these 4 corps are gathered together, it will be very difficult for HuaYe, who does not exceed 350,000 troops, to eat them all, so it is necessary to annihilate the enemy before there is no gathering.
Among them, the first appeasement district is located in Huaiyin, the third appeasement district is located in Jiawang, Xuzhou, the fourth appeasement district is located in Kaifeng (Housu County), and the ninth appeasement district is located in Haizhou.
Feng Zhi'an, commander of the Third Appeasement District, and Deputy Commanders Zhang Kexia, He Jifeng, and Li Wentian, had the following subordinates: the 38th and 180th Divisions of the Fifty-ninth Army (Liu Zhensan); and the 37th and 132nd Divisions of the Seventy-seventh Army (Wang Changhai).
On November 4, Liu Zhi specifically proposed at the military conference: "Assemble all corps to correspond to the four directions of southeast, south, and northwest, and connect with each other, only in this way can we be long-lasting." ”
Commander-in-Chief Liu Zhi, Deputy Commander-in-Chief Du Yuming, Sun Zhen, Liu Ruming, Feng Zhi'an, Han Deloitte, and Li Yannian. Directly under the command of the 20th Army (at the southern end of the Jinpu Railway in central China at the end of the Battle of Huaihai), the 133rd and 134th Divisions; the 260th and provisional 25th Divisions of the 107th Army (which surrendered).
The next day, Huang Baitao arranged for the corps to retreat westward, and 4 armies of 100,000 people (adding a 100th army prepared to support Haizhou on the way) packed up their things and prepared to run.
At this rate, Huang Baitao's corps was about to run back to Xuzhou, but it was delayed by 3 things: First, Zhang Kexia and He Jifeng led the main force of the Third Appeasement Zone to revolt, and Hua Ye was able to go south through Taierzhuang and directly insert Huang Baitao's retreat; second, Li Mi's corps in Mill Zhuang was unwilling to wait for Huang Baitao and returned to Xuzhou first; third, the 44th Army that had been delayed in haizhou was killed.
On November 28, 1948, He Jifeng, Zhang Kexia, Meng Shaolian, Guo Jiafang, Cui Zhenlun, and Yang Gansan led two divisions of the Kuomintang 59th Army, one division of the 77th Army, and 111 regiments in Jiawang and Taierzhuang, with a total of more than 23,000 people successfully revolting.
Huang Baitao was then besieged, and at this time Huang Baitao's 7th Corps was under the jurisdiction of the 40th and 108th Divisions of the 25th Army; the 150th Division and the 162nd Division of the Forty-fourth Army; the 152nd and 186th Divisions of the 63rd Army; the 156th and 159th Divisions of the 64th Army (Liu Zhenxiang); and the 44th and 63rd Divisions of the 100th Army.
Nakano abandoned his original garrison because of Sun Yuanliang and Qiu Qingquan, and also followed him to the vicinity of Xuzhou, and the troops invested by both sides became larger and larger, and the "Little Huaihai" evolved into the "Great Huaihai".
On November 16, 1948, the General Front Committee of the Huaihai Campaign was established, with Liu, Chen, Deng, Su and Tan as members.
