Chapter 3 Chapter 02

After the victory of the War of Resistance Against Japan, with the help of the United States, Chiang Kai-shek quickly airlifted troops to seize Beiping, Tianjin, Tangshan and other big cities, and at the same time dispatched dozens of divisions to Ping, Tianjin and other places along the Tongpu, Pinghan, Pingsui and other railway lines. Advancing and occupying the main towns and communication lines in North China, some towns and vast villages are still under the control of the military and civilians in the Shanxi-Chahar-Hebei and the Shanxi-Hebei-Luyu Liberated Areas. In the first two years of the War of Liberation, the troops of the Shanxi-Chahar-Hebei and Shanxi-Hebei-Luyu military regions of the People's Liberation Army carried out extensive mobile operations on the vast battlefield, wiped out a large number of vital forces of the Kuomintang army, and recovered a lot of lost ground. After the Battle of Shijiazhuang in 1947, the two liberated areas were completely connected, creating favorable conditions for the establishment of a unified North China liberated area.

The strength of the North China People's Liberation Army continued to grow during the first two years of operations. By September 1948, the North China Military Region had 3 field regiments, 11 infantry columns, 31 infantry brigades, and 2 artillery brigades.In addition, the North China Military Region has jurisdiction over seven secondary military regions including Jizhong, Beiyue, Hebei-Luyu, Taihang, Hebei, Taiyue, and Jinzhong.There are a total of 460,000 troops in the region. After the launch of the Liaoshen Campaign in September 1948, in order to cooperate with the Northeast Battlefield and further develop the North China War, the 2nd and 3rd Corps of North China launched the Chasui Campaign in early September. By the end of October, a total of Annihilated more than 20,000 Kuomintang troops, liberated the vast areas of Suiyuan and Chanan, and surrounded Guisui.At the same time, the 1st Corps launched the Taiyuan Campaign and surrounded Taiyuan tightly, completely cutting off the connection between the two major groups of Yan Xishan and Fu Zuoyi.On the Pingbao Line, the 7th Column captured Gu'an City and isolated Baoding.In northern Henan, the 14th Column surrounded Xinxiang and Anyang.These battles not only effectively cooperated with the decisive battle of Liaoshen, but also further weakened the strength of the Kuomintang army in North China, developed the favorable situation in the North China battlefield, and created favorable conditions for the decisive battle in Pingjin.

According to the Fu Zuoyi Group of the Kuomintang guarding North China, there are 4 corps, 12 armies, and 42 divisions. Together with the local security forces, there are more than 500,000 people in total. The troops have American equipment and receive American assistance. Fu Zuoyi is a relatively talented general in the Kuomintang army.Zhu De commented on him in this way: "In combat, he has learned some methods of the Japanese and ours. His strength in North China is now far greater than ours, so Fu Zuoyi is relatively difficult to fight." Fu Zuoyi, courtesy name Yisheng, was born in Ronghe, Shanxi.He joined the army in his early years and served under Yan Xishan. When he participated in the Northern Expedition in 1924, he led his troops to defend Zhuozhou City for three months, and became famous in the first battle. In 1928, he was promoted to the commander-in-chief of the 5th Corps of the 3rd Army and the commander of the Tianjin Garrison. In 1930, he participated in the Jiangyan-Feng War and served as the commander-in-chief of the Yan Army's 2nd Route Army. In 1931, he served as the commander of the 35th Army and the chairman of the Suiyuan Provincial Government.During the Anti-Japanese War, he led his troops to fight the Japanese army many times and made many achievements. In 1938, he served as the deputy commander-in-chief of the Eighth War Zone, and fought against the enemy in Suiyuan Houtaowuyuan. In 1940, the Wuyuan Campaign was launched and Lieutenant General Kazuo Mizukawa, commander of the Japanese Suixi Garrison, was killed.The Great Victory in Wuyuan was the first time since the War of Resistance against Japan that the Kuomintang regained lost territory. The Kuomintang government specially awarded Fu Zuoyi the "Blue Sky and White Sun Medal".At the end of the Anti-Japanese War, Fu Zuoyi became the commander-in-chief of the 11th War Zone, and his power greatly expanded.After the victory of the Anti-Japanese War, Fu Zuoyi faithfully implemented Chiang Kai-shek's anti-communist and anti-people policies. In the first year of the liberation war, he telegraphed the whole country and uttered wild words: "If the Communist Party can win, I, Fu, will hold the whip!"

In order to lure Fu Zuoyi to sacrifice his life to support the crisis in North China, Chiang Kai-shek abolished Sun Lianzhong's Baoding Sui Department in November 1947 after the People's Liberation Army liberated Shijiazhuang, an important town in North China, and established the North China "Bandit Suppression" General Headquarters. The military and political power of Hebei, Shanxi, Rehe, Chahar and Suiyuan) and two cities (Peking and Tianjin) were handed over to Fu Zuoyi.Later, in order to unify military power and command, Chiang Kai-shek simply abolished the North Parallel Army, and put all the Kuomintang Central Army, Youth Army, and Traffic Police Corps in North China under the command of Fu Zuoyi.This was unprecedented for Fu Zuoyi, who was not directly related to Jiang.It can be seen from this that Jiang relied heavily on Fu Zuoyi and had high expectations at that time.

Chiang Kai-shek pinned his hopes on him, and some imperial literati also praised Fu Zuoyi to the sky, comparing him with Zeng Guofan, who "rejuvenated the Qing Dynasty". Fu Zuoyi is deeply impressed by Chiang Kai-shek's reuse.However, he felt that Yan Xishan in Shanxi had the highest seniority among the Kuomintang warlords and had been his immediate boss for many years.Therefore, Fu Zuoyi's scope of power is nominally five provinces and two cities, but actually four provinces and two cities.At this time, Fu Zuoyi was a smash hit, and his power was overwhelming. In December 1947, Fu Zuoyi officially assumed the post of commander-in-chief of the Kuomintang's North China "Suppression General", and led the entire team of the former Zhang Yuansui Department to station in Beiping.

Fu Zuoyi was extremely cautious in using troops, and he refused to use his basic troops unless it was absolutely necessary.But at this time, he was stunned. In order to repay Chiang Kai-shek's kindness, he changed his previous cautious style of using troops and frantically attacked the liberated areas, trying his best to find the main force of the North China People's Liberation Army for a decisive battle.For this reason, he organized the 35th Army, his ace unit, into a motorized unit, together with the newly formed 4th Cavalry Division and artillery unit, and combined them into a mobile corps. He hoped that this mobile unit would make great achievements for himself.

Unexpectedly, the teacher is not good. In January 1948, near Laishui, Fu Zuoyi's elite 35th Army suffered a devastating blow, and the commander Lu Yinglin committed suicide.This defeat was a heavy blow to Fu Zuoyi. He was very sad, and he was restless for days and nights. In October 1948, Fu Zuoyi sent troops to attack Shijiazhuang in an attempt to destroy the Xibaipo Central Committee of the Communist Party of China in order to "find a turning point from the crisis". The Central Committee of the Communist Party of China and the Central Military Commission got Fu Zuoyi's action plan to attack Shijiazhuang in time, and quickly adopted strict deployment: order the 7th and 3rd Columns of North China to resolutely block and annihilate Fu Zuoyi's attack troops; Cheng Zihua, the commander of the 2nd Corps, led the 4th and 11th columns to form an advance corps, marching towards the suburbs of Beiping, threatening the enemy's rear; through radio stations, newspapers and other news media, publicly exposed the conspiracy of Chiang Kai-shek and Fu Zuoyi.

As a result, Fu Zuoyi's sneak attack not only failed to achieve his goal, but put himself in a more disadvantageous situation. In early November, the 2nd North China Corps entered Quyang, Dingxian, and Mancheng, posing a direct threat to the Ping, Tianjin, and Bao triangle areas guarded by Fu Zuoyi; the Northeast Advance Corps had 2 columns, 3 independent divisions, and 1 cavalry division A total of 120,000 people entered the Jixian and Zunhua areas in eastern Hebei, posing a serious threat to the Pinggu, Pingjin, Jintang lines and the two cities of Pingjin.In particular, the entry of the Northeast Advance Corps greatly strengthened the strength of the People's Liberation Army on the North China battlefield, and created more favorable conditions for the main force to enter the pass and launch the Pingjin Campaign.

Under the continuous attack by the People's Liberation Army, the North China "suppression general" Fu Zuoyi Group and the Taiyuan Suiyuan Yan Xishan Group are in an extremely unfavorable situation. In September 1948, more than 100,000 people from Yan Xishan's 6 armies and 16 divisions retreated to the isolated city of Taiyuan.Fu Zuoyi stationed about 40,000 people with 1 army and 3 divisions in Guisui; 1 division with more than 10,000 people stationed in Datong; 12 armies, 42 divisions and local troops: a total of more than 500,000 people, distributed in Shanhaiguan, Tangshan, and Tanggu , Tianjin, Beiping, Zhangjiakou and Chengde, Baoding and other railways.

At that time, the Fu Zuoyi Group had the Northeast "Suppression General" Wei Lihuang Group as a barrier in the north, and the Xuzhou "Suppression General" Liu Zhi Group in the south as a support. Its own military strength was greater than that of the North China Liberation Army, so it was still able to cope with persistence in North China.But after the Liaoshen Campaign ended, Wei Lihuang's entire army was annihilated, and the barrier to the Northeast no longer existed: Liu Zhi Group was trapped in the encirclement of the Central Plains and East China People's Liberation Army, and it was difficult to protect itself.Once the Northeast Field Army's million troops enter the customs, the Fu Zuoyi Group will bear the brunt.

Fu Zuoyi had long thought about the retreat of Ping and Tianjin. In the spring of 1948, shortly after taking office as the North China "Suppression General", he flew to Taiyuan to ask Yan Xishan for advice on good strategies. After discussing the situation in North China, Yan Xishan proposed three strategies: top, middle, and bottom. The best strategy: Build 10,000 to 20,000 strong fortresses, densely distributed along the line from Tangshan to Tanggu and Tianjin, to prevent the Northeast Lin Biao's troops from entering the pass, or consume and annihilate the Northeast Communist Army attacking into the pass; Central strategy: Withdraw from Beiping, guard the line from Zhangjiakou to Baotou, and form a corner with the Majia army in Shanxi and Hexi; The worst policy: stick to Peiping. Although Fu Zuoyi repeatedly praised Yan Xishan's strategy on the surface, he believed that this tactic was too conservative in his heart, so he adopted the policy of "protecting Beiping with mobile tactics", centering on Beiping, and focusing on the Pingjinbao triangle area. , back and forth mobile operations on the Beining, Pingsui, and Pingbao lines. After the Liaoshen Campaign began, Fu Zuoyi began to feel that the situation in North China was facing a crisis, and the issue of Pingjin's retreat was at hand. He believes that in the unfavorable situation of the war, retreating to Suiyuan to the west is a more feasible plan, so that he can take away his basic troops and keep his basic base.However, there are also difficulties in retreating to Suiyuan. First, he can only take away his own troops, and he cannot take away the Central Army; second, there is Ma Hongkui in the northwest, so it is difficult to cooperate; .Therefore, unless it is absolutely necessary, we must give up Pingjin without a fight to protect a corner of Suiyuan. Fu Zuoyi believes that the more ideal solution is to temporarily stay in Pingjin, expand its strength, and strive for US aid, waiting for the situation to change. He believed that he had strong soldiers and horses in his hands, and the People's Liberation Army had nothing to do with him for a while, thinking that "the current situation is serious, but it is not serious enough to threaten the survival of North China."Because at that time, the three corps of the North China Liberation Army were besieging Taiyuan respectively, going west to Guisui and south to Pingbao Line to fight, and their forces were not concentrated.Compared with the North China Communist Army, its own strength has an advantage.As long as the Northeast Field Army does not enter the customs, the North China Liberation Army alone will not pose a fatal threat to it.He believes that after more than 50 days of continuous combat, the Northeast People's Liberation Army cannot enter the customs without four or five months of rest and replenishment. After the Liaoshen Campaign ended, the North China Kuomintang army faced a joint attack from the Northeast and North China People's Liberation Army. For Chiang Kai-shek, whether to withdraw or defend was an imminent issue. On November 3, the Nanjing Ministry of National Defense held a combat meeting to urgently discuss the combat policy in North China.Defense Minister He Yingqin proposed two options: First, taking advantage of the opportunity when the East China People's Liberation Army was concentrating its forces for the Huaihai Campaign and the Jinan area had fewer defensive forces, Fu Zuoyi went south to attack Jinan, and then fought in Shandong.The advantage of this plan is that it can not only withdraw the North China Army, but also contain the East China Liberation Army so that it cannot carry out the Huaihai Campaign with all its strength, thereby reducing the pressure on the Xuzhou "suppression general" Liu Zhi Group.The disadvantage is that going south to Jinan from the Pingjin area has to pass through the liberated areas of nearly a thousand miles, and there will be heavy losses along the way.Therefore, the second plan is to withdraw Fu Zuoyi's entire army to the south. The first step is to transport it to Qingdao, and the second step is to transport it to Jiangnan. Although Chiang Kai-shek basically agreed to withdraw the northern China troops to the south, he was full of contradictions about giving up Ping and Tianjin without a fight. On the one hand, the Xuzhou Liuzhi Group faces a joint attack from the two major field armies in East China and the Central Plains, and its future is in danger.If Xu and Beng were lost, Nanjing and Shanghai, the ruling centers of the Kuomintang, would be exposed to the direct attack of the People's Liberation Army. Therefore, it is urgent to increase the troops on the Xu and Beng battlefield and strengthen the deployment of the Yangtze River defense line. The North China Fu Zuoyi Group is the only force that can be mobilized.Therefore, Chiang Kai-shek desperately wanted to withdraw Fu Zuoyi's group to the south. On the other hand, if the Fu Zuoyi Group were withdrawn, it would be tantamount to abandoning Ping, Tianjin, and North China, which would have serious political consequences.At the same time, the safe withdrawal of this huge force is also a question.If we withdraw from the land to the south, we have to go through the vast liberated areas and the natural danger of the Yellow River, and there is little hope of success; if we withdraw from the sea to the south, the transport capacity is insufficient and the time is too late.In addition, if Fu Zuoyi sticks to Pingjin, he can contain the Northeast and North China Liberation Army for a period of time, so as to gain time to organize the defense of the Yangtze River. Chiang Kai-shek believed that "Although the Northeast military failed, its political, economic, and military foundations in the pass have not been shaken at all. Compared with the strength of the Communist bandits, they still have an advantage." deployment, the Communist bandits and criminals will not be able to take advantage of it.” "Commander-in-Chief Fu's combat spirit and strategic use are extremely brave and well prepared."As long as "the combat power is strengthened at the right time, the entire war situation will be safe." Chiang Kai-shek also pinned his hope of saving the crisis in North China on the changes in the international situation. At the end of October, when he convened a lecture with senior generals above the commander of the army in Peiping, he said: "The key to overcoming chaos and victory is that the Third World War will inevitably break out with the United States and the Soviet Union as the main opponents. The United States and the Soviet Union must fight. Soviet Russia must be defeated, and the United States must be defeated." America's victory is our victory." This kind of contradictory psychology made Chiang Kai-shek hesitate to decide whether to retreat or defend. On November 4, the second day after the end of the Liaoshen Campaign, Chiang Kai-shek summoned Fu Zuoyi to Nanjing to attend the highest emergency military meeting. Chiang Kai-shek believed that the North China garrison was in danger of pincer attack. Therefore, in order to concentrate his forces in the Xubeng area for a decisive battle with Chen Yi and Liu Bocheng's East China and Central Plains field armies, and at the same time prevent the North China garrison from waiting to be wiped out, he advocated abandoning Pingjin and sending Fu Zuoyi's Nearly 600,000 troops from four corps were transferred to the south. Chiang Kai-shek's intention was to concentrate his forces in the Xubeng area to decide the outcome, reverse the Central Plains in one fell swoop and change the national situation.Even if Xu Bang loses, it can still prompt half of the south of the Yangtze River to fight a protracted war with the People's Liberation Army.For this reason, Jiang Xufu took the important position of "Southeast Chief Executive", hoping to make Fu Zuoyi tempted to go south. Fu Zuoyi has worked with Chiang Kai-shek for many years, and he knows Chiang Kai-shek well.Although Chiang Kai-shek valued his talents and handed over the military and political power of the entire North China to him, he knew in his heart that he was not Chiang's direct descendant after all. Chiang Kai-shek always rejected dissidents. Sooner or later, the money that Nian painstakingly worked on will be swallowed up by Jiang.Moreover, Fu Zuoyi made his fortune with the 35th Army, and his base was in Suiyuan. Most of his soldiers, such as the 35th Army, were from the Suiyuan area. It is difficult for Fu Zuoyi to bring them to the south of the Yangtze River. .More importantly, Fu Zuoyi and Xu Heng realized that following Chiang Kai-shek to the end may not lead to good results. Therefore, Fu Zuoyi decided that he could not leave North China. No matter what Chiang Kai-shek said, Fu Zuoyi would not leave North China. Fu Zuoyi's reason is very sufficient, that is, withdrawal is always necessary, but now is not the time to withdraw without a fight.After the Liaoshen Campaign, the Northeast Field Army must have lost a lot of troops.It takes at least 3 months of rest before entering the customs. Within 3 months, Fu Zuoyi was fully able to support the situation in North China and the Battle of Xu Bang in East China with his existing troops of more than 500,000 troops. Fu Zuoyi made a generous statement: "The southward withdrawal plan cannot be implemented when it is absolutely necessary. Sticking to North China is the overall situation, and retreating to the southeast is partial security. The lessons of history are worth pondering. If half of the country is easily handed over to others, it will affect international prestige." Fu Zuoyi's big words actually convinced Chiang Kai-shek.Chiang Kai-shek finally decided to adopt the policy of temporarily guarding Pingjin, maintaining Haikou, expanding strength, and observing time changes. In order to encourage Fu Zuoyi to stick to Pingjin, Chiang Kai-shek not only handed over the party, government, military, and economic power in North China to Fu Zuoyi, but also allowed him to receive American aid directly without going through the Nanjing government. Bullets supplement Fu Zuoyi's department. After Fu Zuoyi returned to Peiping, he took measures and readjusted his deployment starting from mid-November. In the spring of 1948, based on his experience in defending Taiyuan, Yan Xishan repeatedly promoted his "fortress tactics" to Fu Zuoyi.Yan Xishan believes that Fu Zuoyi's "mobile tactics" can be effective against the guerrilla tactics of the North China Communist Army for a while, but it will not work against the hundreds of thousands of troops in the Northeast.An effective way to deal with the Communist army's entry into the customs is to adopt "fortress tactics", that is, "build 10,000 to 20,000 blockhouses between Tangshan, Tanggu, and Tianjin." Yan Xishan said that if the Northeast Communist Army wanted to enter the pass, they had to attack the blockhouses.These bunkers can not only suck it from moving forward, but also consume its strength.If each bunker can consume 100 or even 200 of its people, you can win. "If you have won a few victories, why don't you worry about the US aid not coming. Once the US aid arrives, the achievement of suppressing the bandits will be completed. If you don't do this, you may die without a place to die." At that time, Fu Zuoyi believed that he was powerful and did not need to adopt such a passive strategy.But that moment, this moment also.Now, Fu Zuoyi began to consider using this attrition tactic. Therefore, he stepped up the recruitment of migrant workers, vigorously strengthened the fortifications of Beiping, Tianjin, Zhangjiakou and other cities and the peripheral fortifications of Tanggu Seaport, and personally sent Song Kentang, the deputy commander-in-chief of the "Suppression General", to station in Tanggu to supervise and inspect the road protection on Beining Road. fortifications.He also repeatedly instructed Tianjin Police Commander Chen Changjie and Tianjin Mayor Du Jianshi to strengthen Tianjin's city defenses and make "Great Tianjin a fortress." Fu Zuoyi realized that after the Northeast People's Liberation Army entered the customs, it would have an advantage in military strength.To this end, a plan to expand the army by 200,000 to 500,000 people was formulated to strive for a quantitative balance.He ordered Hebei and Suiyuan provinces to step up their military expansion, form one to three security regiments in each county, and ordered the local security regiments to be organized into regular troops.At the same time, all provinces were instructed to purchase food as soon as possible to prepare for wartime. In terms of troop deployment, shorten the front line.He did not follow Chiang Kai-shek's request to concentrate the main force in the Tianjin, Tang, and Tang areas, but placed 17 divisions of his direct troops in the eastern section of Pingsui Road and the area west of Beiping to ensure the retreat of Suiyuan to the west; The 25 divisions of Jiang's troops were deployed in the Pingjintang section of the Beining line and the area east of Beiping to prevent the Northeast People's Liberation Army from entering the customs and maintain sea passages so that they could go their separate ways when the situation was unfavorable. He placed the 4th and 9th Corps, the 13th Army, 16th Army, and 31st Army of the Chiang Kai-shek Central Army, and the 35th Army, 101st Army, and 104th Army of the Fu Family Army in Beiping and its vicinity; The 62nd Army, 86th Army, 87th Army, 92nd Army, and 94th Army were placed on the front lines of Tianjin, Tanggu, Tangshan, and Luan County; the 11th Corps of the Fu Family Army and the 105th Army were placed in Zhangjiakou, Zhangbei, and Xuanhua; The 4 divisions of the 5th Army defended Guisui in Suiyuan, and the 275th Division defended Datong in Shanxi. In this way, in order to implement the policy of taking into account both fleeing and defending, and observing time changes, Fu Zuoyi deployed the main force on a front more than 500 kilometers long from Tanggu Haikou in the east to Zhangjiakou in the west, forming a long snake formation.Snake head; Tangshan, Tianjin, snake belly in Beiping, snake tail in Xuanhua, Zhangjiakou. Fu Zuoyi's intention was that once the Northeast Field Army entered the pass and the defenders couldn't hold on, they would adopt the policy of fleeing, so that things would be convenient.In the west, people can escape from Suiyuan, and then go west; in the east, they can retreat south from the sea. This deployment shows that the North China Kuomintang Army has become a "frightened bird" and may conduct a strategic general retreat at any time. The operational policy and determined operational deployment formulated by the Central Military Commission and Mao Zedong were to wield the two strategic groups of the Northeast Field Army and the North China Field Army to strategically encircle and divide the Fu Zuoyi Group, cutting off its southward retreat and westward retreat. The enemy has changed from a "bird of fright" to a "bird in a cage" in order to achieve the campaign goal of suppressing and annihilating North China on the spot. Pingsui Road is the lifeline connecting Suiyuan (now Inner Mongolia Autonomous Region) behind Fu's army, and Zhangjiakou is the strategic hub of Pingsui Road.By encircling Zhangjiakou and cutting Pingsui Road, we will be able to capture the Fu family and drag the Jiang family.Mao Zedong knew himself and the enemy, and his judgment was accurate.In his telegram to the Northeast Advance Corps and the North China 2nd and 3rd Corps on November 27, 1948, he pointed out: The enemy has 8 infantry divisions and 3 cavalry brigades in Zhangjiakou, Xuanhua, and Huailai areas. After surrounding these enemies, the 16th Army and 35th Army located near Beige are very likely to send reinforcements. If within a month, we can seize and wrestle the above-mentioned 16 infantry divisions and brigades on the Pingzhang line, and annihilate part of them, so that the enemy can't move, can't flee west or east, that is a great strategic victory . Later, he instructed the 3rd North China Corps: Your task is to encircle several enemy units in order to mobilize the enemy from the east to help from the west, so the focus is not on annihilation, but on encirclement.After you surround a few enemy units, it is important to build a tight perimeter so that they don't escape. Yang Chengwu, commander of the 3rd North China Corps, and Li Tianhuan, deputy political commissar, led the 1st, 2nd, and 6th columns, secretly and quickly marched eastward from Suiyuan on November 25th and 26th, and went to Zhangjiakou and Xuanhua.On the way to the east, there are troops of our army everywhere, red flags are flying, horses are neighing, and the troops are in high spirits and fighting spirit. Yang Chengwu was riding on a horse, looking at the brigade running eastward, comprehending the profound connotation of the mission assigned by Chairman Mao Zedong to the 3rd Corps. Zhangjiakou is located about 180 kilometers northwest of Beiping. It was Fu Zuoyi's strategically important place to defend Beiping, and it was also the only way for Fu Zuoyi to escape to Sui (now Hohhot).It is surrounded by mountains on three sides in the east, west and north, with the Dayang River in the south and the ancient Great Wall in the north. The terrain is high in the north and low in the south, and the terrain in the south of the city is open.The Qingshui River runs through the north and south, and the north of the city is a long and narrow valley. In the early morning, Zhangjiakou, a heroic mountain city that has attracted the attention of the people all over the country, has appeared on the horizon under the multi-color glow. The ancient Great Wall, East and West Taiping Mountains and the buildings in the city are still the same. When the troops arrived at the combat area, according to the instructions of the Military Commission, they first surrounded the enemies of Zhangjiakou, Huai'an, Chaigoubao, and Zhoujiahe. The reconnaissance learned that the enemy stationed at Chaigoubao was the 21st Division, which had already withdrawn to the Kongjiazhuang line outside Zhangjiakou, leaving only two companies of the 12th Cavalry Brigade and the security forces. At dawn on November 30, the 5th Brigade of the 2nd Column quickly wiped out the enemy at Chaigoubao, and took advantage of the victory to attack and occupy the left guard that night.At the same time, the first column occupied Huai'an, and then crossed the Yanghe River to occupy Shalingzi, cutting off the passage between Zhangjiakou and Xuanhua.The 6th Column captured Wanquan and Guoleizhuang, and captured more than 2,000 enemies.In this way, our North China 3rd Corps has approached Zhangjiakou from the east, south, and west. The troops of the Beiyue Military Region and the 3rd and 5th Cavalry Divisions surrounded the enemy in Zhangbei from the north, posing a serious threat to the west front of the Fu Zuoyi Group.
