After Fu Zuoyi defended Zhuozhou, he became famous, and in the War of Resistance Against Japan, he defended Taiyuan, attacked Baotou, fought Suixi, recovered the five plains, and wrote a glorious page for the country and the people. After the start of the Liberation War, there were 4 classic battles, 1, the Suiyuan Campaign 2, the Datong Jining Campaign 3, the Zhangjiakou Campaign 4, and the Northeast Reinforcement Campaign.

After the outbreak of the full-scale civil war in 1946, the Central Military Commission gave the Shanxi-Chahar-Hebei Military Region the combat task of seizing three roads (Pinghan, Zhengtai, Tongpu) and four cities (Baoding, Shijiazhuang, Taiyuan, Datong). After the Jinsui Military Region and some troops of the Shanxi-Chahar-Hebei Military Region launched the Northern Shanxi Campaign. The liberation of 10 county seats, the control of a large area of land, the isolation of Datong, created a good opportunity to launch the Datong campaign.

Datong is a famous coal capital in China, the connection point of Pingsui and Tongpu railways, and the transportation key point connecting Shanxi and Hebei. It has always been a place for soldiers to fight, Datong is controlled by Yan Xishan, and the horizontal stalk is in the middle of the two base areas of Jinsui and Jinchaji, and taking Datong can make the two base areas one gas. Therefore, the Jin-Cha-Ji and Jinsui Military Region decided to attack Datong and form the Datong Front-line Command, with Zhang Zongxun, deputy commander of the Jin-Chahar-Hebei Military Region, as the commander-in-chief, and Luo Ruiqing, deputy political commissar of the Jin-Chahar-Hebei Military Region, as the political commissar, to mobilize all the main forces of the two theaters, a total of 50 regiments, and more than 100,000 people, such a large corps operation was an unprecedented large-scale campaign from the War of Resistance to the beginning of the Civil War, the 1st, 2nd, 3rd, and 4th columns of the Shanxi-Chahar-Hebei Military Region and local troops all participated in the battle, and the main forces of the Jinsui Military Region all participated in the battle, and the specific division of labor was 358 Brigade, the second regiment of the Fifth Army Division, The 3rd Column and Teaching Brigade, the Artillery Regiment, and the 12th and 13th Independent Regiments of the First Army Division served as the Datong attack mission, and the 10th Brigade of the Fourth Column also went north to participate in the Datong operation after capturing Yingxian; With the 1st and 3rd Independent Brigades and Cavalry Brigade of the Jinsui Military Region, the 7th and 9th Regiments of the Suimeng Military Region and the 4th Brigade of the 2nd Column of the Shanxi-Chahar-Hebei Military Region, the 1st Column of the Shanxi-Chahar-Hebei Military Region served as reinforcements to block Fu Zuoyi's troops, and the Zhangjiakou Garrison Headquarters taught the brigade to go to Xintang to participate in the reinforcements after completing the peripheral operations in Datong. In this way, both the offensive and the reinforcements were superior, and on July 31, 46, the Battle of Datong was launched.

The scale of the Datong campaign was so large, the determination was so great, and the strategic purpose was clear; First, eliminate the living forces of Yan Xishan and Fu Zuoyi; Second, remove the obstacles from Yan'an to Zhangjiakou and complete the unfinished strategic objectives of the Suiyuan Campaign.

The Datong garrison of the National Army is the 38th Division, the 5th and 6th Divisions of the Mazhan Mountain Cavalry Advance in the Northeast, the Security Corps, two artillery battalions, a special service battalion and an engineer company. A total of more than 19,000 people, commanded by Chu Xichun, deputy commander-in-chief of Yan Xishan's Eighth Group Army. Our army evaluated it as chaotic and unified, complex in composition, 19,000 troops belonging to 7 or 8 units, low combat effectiveness, the 38th Division was temporarily incorporated by a large number of puppet troops, although Datong was firmly walled, the terrain was dangerous, easy to defend and difficult to attack, and the fortifications were solid, our army was sure to capture it with absolute superiority.

For the reinforcements of the Fu Department, Zhang and Luo also prepared in advance, the only brigade of the Jinsui Military Region guarded Zhuozi Mountain, the 3rd Independent Brigade drew out the 27th Regiment to guard Jining (together with the two regiments of the Suimeng Military Region), and the cavalry brigade guarded Tucheng in the northwest of Jining; The Ninth Regiment of the Suimeng Military Region is located in the 18th Taiwan, and the Fourth Brigade of the Jinsui Military Region is located on the front line of Shangdu. With the 3rd Independent Brigade, the 7th Regiment of the Suimeng Military Region, the Independent Cavalry Regiment in Liangcheng, and the Zhangjiakou Teaching Brigade in Xintang, as the reinforcement of the left wing corps, it was commanded by Yang Jiarui, commander of the 3rd Independent Brigade.

Our army launched an offensive on July 31, first attacking the outer positions of Datong, and after more than 30 days of fierce battles for the periphery, it has occupied all the important strongholds and Dongguan on the periphery, eliminated more than 2,000 enemies, and approached the city of Datong. Seeing that Datong was in danger, the guard general Chu Xichun repeatedly appealed to Yan Xishan and asked for reinforcements, but Yan Yuanshui could not save the fire, and the railway from Taiyuan to Datong had been cut off, so he could not send troops, so he had to ask Chiang Kai-shek for help. At this time, Chiang's troops were also trapped in various battlefields across the country, and he could not draw reinforcements.

At that time, the only mobile force was in the Fu Zuoyi Department in Guisui, and Fu took a wait-and-see attitude towards Datong, which did not belong to his jurisdiction, and the Fu army could be regarded as an outlier in the national army, which was influenced by our army and had the style of the People's Liberation Army, such as not afraid of hardship, good at night fighting, good at close combat, hand-to-hand combat, etc., but also with the habits of the old army. Chiang Kai-shek, in order to induce Fu Zuoyi to send troops to reinforce Datong, used his usual tactics in the warlord civil war, gave the territory, added officials to the knighthood, and placed Datong under the jurisdiction of the 12th theater of operations.

After receiving Chiang's order, Fu summoned his close generals, Dong Qiwu, Sun Lanfeng, Guo Jingyun, An Chunshan, Yang Weiyuan, Liu Chunfang, Liu Wanchun, and all officers above the regimental level to attend a secret military meeting in Guisui. When these officers arrived in Guisui (present-day Hohhot), they held a seven-day military meeting behind closed doors to make strict arrangements and plans. Fu Zuoyi gave repeated speeches, explaining military essentials, studying operational methods, and agitating ideologically. In order to win this decisive battle, Fu locked all his officers in the camp and did not allow them to go home for food and lodging, and the discipline was very strict, much stricter than Chiang's descendants, so there was no leakage. In addition, in order to prevent leakage of secrets, Fu did not use the Kuomintang army to share the password, which also made it difficult for our army to grasp its movements.

After the meeting, Fu's chief of staff, Li Shijie, went to Lushan in person to report the action plan to Chiang, and Chiang was extremely satisfied after reading the action plan. Fu sent three people, the north route Tao Lin soldiers into Jining, the south road out of Sui, the Liangcheng, the middle road out of Sui to attack Zhuozi. Among the 3 people, the middle lane is real, and the two wings are empty, only suspicious soldiers. Take Zhuo Zi, encircling Ning will definitely lead to Datong and our army will divide troops to the north. As long as Fu Bu defeats the reinforcements of our army, Datong's predicament will naturally be alleviated. After that, Fu Bu took advantage of the situation to move eastward and approached Zhangjiakou. "This is indeed a very clever strategy and tactic, according to common military common sense. Datong is in danger, emergency rescue is like fighting fire, should be along the highway straight into Liangcheng, Fengzhen, straight to Datong to solve the siege.

How could it be possible to seek the near and far and attack Jining, but if you look at the map carefully and ponder it, you can suddenly realize that you can attack Liangcheng and Fengzhen along the highway. Our army has long been prepared, there is no surprise effect, and time-consuming and laborious, heavy casualties, contrary to expectations, with absolutely weak forces to attack the strong enemy preset blocking, not to make even their own compensation, at that time our mobile reinforcement force 4 brigades have been concentrated in Maihutu, if Fu's main force is really Shunliangcheng, Fengzhen to attack. Then it is in the arms of our army, and when the Datong offensive troops can also draw out 5-6 brigades to encircle and annihilate the Fu army. And to attack Jining, is to be surprised, attack its unprepared, kill two birds with one stone, capture Jining, to the southeast can send troops to Fengzhen, Longshengzhuang. Outflanking and attacking our army in Datong from the rear is too much of a threat to our Datong attacking troops, and we will want to get rid of it. After capturing Jining, we can send troops to the east to Shangyi and Zhangbei, and directly threaten Zhangjiakou, the capital of our Shanxi-Chahar-Hebei Military Region. Therefore, attacking Jining is to attack it and must be saved, which is really a high move. It is also the only trick for weak soldiers to break the siege and win. It is the most successful example of the use of modern warfare to encircle Wei and save Zhao.

Judging from Mao's special attention to Jining, the People's Liberation Army is bound to go all out to help, after Fu occupied Zhuozi Mountain on September 5, He and Nie have formulated a policy of resolutely guarding Jining, and reported to the Military Commission, Mao ** attaches great importance to Jining, and immediately called back: "The deployment is very good, and I hope to deal with it according to the facts...... Order the Jining garrison to defend to the death, and not give up under any circumstances, otherwise discipline will be enforced. It can be seen how much Mao attaches importance to Jining.

The timing of Fu's dispatch was just right, and it chose to suddenly send eastward aid at a time when the Datong People's Liberation Army was clearing the Datong Pass with all its strength and was concentrating on attacking the city wall. This caused great difficulties for the PLA to turn around sharply and deal with Fu Zuoyi.

On September 3, 1946, Fu sent his number one general, Dong Qiwu, commander of the Provisional Third Army, to lead the Provisional 11th Division and the Provisional 17th Division of the main force of the Provisional Third Army (owed the Provisional 10th Division), and the new 31st Division of An Chunshan, another main force, with a total of 130,000 people, from the middle route; The main force of Sun Lanfeng's cavalry, with a total of more than 3,000 people, was dispatched from the northern front, and the two armies were the first-line attacking troops, swooping down in the direction of Zhuozi-Jining. Guo Jingyun's 101st Division of the 35th Army, Li Mingding's new 32nd Division, Wei Jinglin's mobile troops, and Liu Chunfang's 4th Cavalry Division were second-line troops, which were then reinforced. The total strength of the enemy was about 320,000 men from 2 divisions of the 3rd Army, 3 divisions of the 35th Army and 4 cavalry divisions

The Temporary Third Army marched to Zhuozi through Fushengzhuang, and the new 31st Division advanced from Taolin to the northeast of Zhuozi, and after the two armies met, the Temporary 17th Division and the New 31st Division of the Provisional Third Army carried out an east-west flanking attack on Zhuozi Mountain. The 101st Division and the Mobile Unit followed suit and prepared for support. The enemy's cavalry on the northern front attacked the large and small earth cities northwest of Jining in a roundabout way, threatening the flank. The enemy's 4th Cavalry Brigade on the southern front captured the outlying stronghold of Zhuozi Mountain.

Before the war, Wang Shangrong and Zhu Huizhao went deep into the army to mobilize the troops for combat mobilization, implemented the defensive deployment, carefully planned, and deployed as follows; Organize the defense with the deployment of the second regiment on the high ground on the summit west of Zhuozi Mountain; The 3rd Battalion of the 35th Regiment organized a defense in the northeastern highlands of Zhuozi Mountain, and the main force of the regiment was deployed in the second echelon of Da Nangou and Xiaonangou, preparing to carry out a counterattack to the top of the mountain to the west; The main force of the 714th Regiment was a mobile force, and a company covered the flank of the 2nd Regiment on the southwest heights. Before dawn on 5 September, the enemy attacked the Zhuozi Mountain position with three divisions, the new 31st Division of Anchunshan, and the 11th and 17th Divisions of the Provisional Army, under the cover of powerful artillery fire from an artillery regiment. The 2nd Regiment held its ground, resisted stubbornly, and repelled several successive attacks by the attackers in companies and battalions. At about 12 o'clock in the afternoon, the position of the second battalion on the top of the west mountain was lost, and the instructor Wang Chenglie died. The Special Service Company and the Third Company carried out a counter-attack. Prevent the enemy from expanding. After occupying the high ground east of Toudaogou, the enemy on the northern front quickly carried out a roundabout encirclement to the south of Zhuozi Mountain. The enemy, who was attacking along the southern side of the railway, also broke through the position of the first battalion and launched a roundabout encirclement of Zhuozi Mountain from the west. The main force of the 714th Regiment was deployed too far away and there was no time for reinforcements, the situation was bad, and its scenario was almost like a PLA movement encirclement. Wang Shangrong had to take the initiative to withdraw to the southeast before the enemy encircled him, so as not to be surrounded and destroyed, which was the most unfortunate battle in Wang's life. It was originally scheduled to be held for three days, but in fact it only lasted eight hours, far from completing the planned defense plan, and more than 500 people were killed or wounded.
