Don't blame the military family for fighting for this place, and drive straight to control Youyan. ”

The deployment of the PLA and the course of the battle are as follows: Zheng Weishan urgently ordered the teaching brigade not to retreat, and immediately switched to a mobile defense on the road between the wolf's nest and Zhangjiakou, delayed the enemy with resolute fighting, blocked the attack step by step, and moved towards Zhangjiakou to cover the retreat of the party, government, and army in Zhangjiakou.

At 17 o'clock on the 10th, the remaining troops of the teaching brigade retreated to the Nantianmen area of Zhangjiakou to make defensive deployments and prepare to live and die with Zhangjiakou.

On the side of the national army, at 7 o'clock in the morning of October 10, the Fu cavalry unit occupying the county town of Zhangbei made a tentative attack on the wolf's nest. Dong Qiwu Fu is the main force, and set off from Jining Rose Camp on October 8, because of Shangyi in the north of Chacha, Daqinggou is a barren mountain road, and the road conditions are poor. The infantry did not have much of a problem, but the cars, tanks, and artillery wagons of the mechanized troops were indeed too difficult to march, so they had to continue to advance while repairing the roads. During such a march, the speed of the car could not even catch up with the cavalry, so they had to stay near the Taiji Temple that day.

On the 9th, the troops continued to advance and crossed Shangyi County. In the evening, Dong Qiwu received a notice from Sun Lanfeng and a report from Fu Zuoyi, and learned that the Fourth Cavalry Division had captured Zhangbei County at about 5 p.m. on the 9th. Fu Zuoyi ordered Dong Qi's military troops to advance at the same time, and on the next day (10th), with the strong cooperation and coordination of the cavalry troops, they captured the Wolf's Nest Valley, and went straight to Zhangjiakou through Wanquan County. He also told the Li Wen Group Army in the Huailai area that it had coordinated its advance in the direction of Zhangjiakou. He also ordered Lu Yinglin to lead the 35th Army to rush to Zhangbei by car in the starry night, thinking that the army would be a backup.

At about 10 o'clock on the morning of the 10th, when the 1O1 Division of the advance guard unit arrived in the vicinity of the area north of the wolf's nest, it immediately attacked the People's Liberation Army defending the wolf's nest on the mountain. Wolf's nest ditch is a military point in the north of Zhangjiakou, is the barrier of the north of Zhangjiakou, between Zhangbei and Zhangjiakou, the terrain is very dangerous, the mountains on both sides are steep, a canyon in the middle, the highway passes through it. As far as the mountainous terrain is concerned, there is a great tendency of "one man is the pass, and ten thousand men are invincible." With such a dangerous terrain, it is reasonable for the PLA to guard it with one brigade and one battalion. After the 1O1 Division was ordered, Division Commander Guo Jingyun immediately ordered the 3O1 Regiment of the division (Regiment Commander Wei Jinglin) to attack the PLA on the hills on both sides of the road. Under the cover of bombing and strafing by 1O5** artillery, mountain artillery, mortars and six aircraft, the attack began relatively smoothly, and when it reached a high ground on the right side of the road, the PLA relied on favorable terrain and strong fortifications to resist vigorously. The regiment was held back and repeated several attacks, all of which were successful. One of the reasons for this is that the PLA calmly responds to the battle and does not start shooting at an effective range or close range; Second, because the distance between the two sides was too close, the aircraft and artillery were ineffective. In order to reduce the casualties of the troops, the regiment later changed its method and used part of its forces to carry out a feint attack from the front, and another force to attack from both sides in a roundabout way, but it did not attack the mountain. Seeing that the regiment could not overcome repeated attacks, Division Commander Guo Jingyun personally led the 3O2 Regiment (regiment commander Feng Zi) to rush to support, preparing to personally command the two regiments to carry out a strong attack under the cover of aircraft and artillery.

At this time, the signal corps of the military headquarters suddenly took a long-distance telephone line from Zhangbei to Zhangjiakou; The People's Liberation Army, which overheard the Wolf's Nest, was reporting the situation to the Zhangjiakou Headquarters, saying: "The regular infantry and cavalry of Fu Zuoyi's army, under the cover of aircraft and artillery, fiercely attacked the position on the Wolf's Nest Mountain, and the battle was very fierce, and it was requested to send reinforcements. The Zhangjiakou People's Liberation Army command said: "We must resolutely resist it, and we must hold out until dusk before reinforcements can arrive." After Dong Qiwu learned of this situation, he immediately ordered Guo's division to attack quickly, so as to take down the mountains on both sides of the wolf's nest before dusk before the arrival of PLA reinforcements. Guo Jingyun immediately commanded two regiments, 3O1 and 3O2, to launch a general attack on the PLA position. However, due to the dangerous mountain situation in front of him, he attacked many times, but he did not succeed; The detour troops went around the mountain too far, and the mountain was high and the slope was steep, and the two did not cooperate with each other, and the result was still no progress. At about 3 p.m., the plane reported to Dong Qiwu in the air: "The plane can only cover and cooperate with the operation until 4 p.m., and after 4 p.m., due to the weather, it can no longer cooperate in the operation, and I hope that the infantry can quickly capture the hilltop position with the coordinated support of the aircraft." ”

After hearing this, Dong was very anxious. Division Commander Guo Jingyun failed to succeed in several attacks, and asked to send tank troops to support. Dong Qiwu could no longer cooperate with the operation after 4 p.m., and he felt that time was pressing and could not be delayed any longer. If you can't attack the top of the wolf's nest before dusk, you won't be able to attack Zhangjiakou. Jin Shuke was then ordered to send tank troops to support the 1O1 Division, hoping to capture the Wolf's Den Valleys before dusk.

Company Commander Wang Zirong led the company's 12 Japanese-style Type 97 medium tanks to cooperate with the mountain attack troops to attack the PLA position. At the same time, planes and artillery also concentrated their firepower to bomb and shoot together, and the infantry, under the cover of 12 medium-sized tanks, attacked the wolf's nest on the afternoon of October 10. Tank units played a big role in this battle.

When the 1O1 Division was attacking fiercely under the cover of tanks, aircraft, and artillery, the signal corps of the military headquarters overheard the PLA in the wolf's den from the phone, and called the Zhangjiakou headquarters and said: "Fu Zuoyi's army used its powerful forces to launch a fierce attack on our army under the cover of tanks, planes, and artillery. To hold out until dusk, the troops will suffer heavy losses. "The Zhangjiakou command immediately instructed;" That being the case, the sky is about to dusk, and you have successfully completed the task of blocking the attack, so you can leave the battle and turn to Zhangjiakou. Encouraged by this news, the Fu army, which was attacking, doubled its confidence and captured the main position of the wolf's den in one go.

After Fu Jun occupied the wolf's nest at about 5 p.m. on the 10th, it was about to be dusk, fearing that it would continue to advance at night, and was ambushed, and camped in the area near the wolf's nest and ditch that night. After Dong Qiwu reported to Fu Zuoyi by telegraph and wireless telephone on the course of the day's battle, he immediately convened a meeting of his staff and commanders of various units at a large shop next to the highway to study the next day's action and the operational plan for attacking Zhangjiakou. The meeting decided to set off at 7 a.m. the next day (11th) to attack and advance towards Wanquan County, still with the 1O1 Division as the vanguard. The attack was deployed as follows: the 1O1 Division was a feint force, which launched the attack first and attracted the main force of the PLA to the division. He first sent a division to capture Ci'er Mountain west of Zhangjiakou, covering the division to attack from the direction of Xipingmen, occupying Xiabao in the center of Zhangjiakou, expanding the results of the battle to Wucheng Street and Yi'an Street, and occupying the southern half of Zhangjiakou City. An Chunshan's new 31st Division is the mainstay

The attacking troops attacked in the direction of Dajingmen in the north of Zhangjiakou, first captured Shangbao, and then expanded the results to Mingde North and South Streets, occupying the northern half of Zhangjiakou City and the eastern slope area. For the time being, the 11th Division and the mechanized troops are the general reserves, which are controlled in the area between Xipingmen and Dajingmen, so as to support the attack of the 101st Division and the new 31st Division at any time. He also sent a telegram to Fu Zuoyi and Sun Lanfeng, requesting that the cavalry troops be ordered to occupy the commanding heights of Rentou Mountain east of Zhangjiakou from the area east of Dajingmen to support the siege troops. After the meeting, Dong Qiwu rested overnight in the Chema Store in an excited and nervous mood.

At 7 o'clock in the morning on the 11th, Fu's army assembled to attack Zhangjiakou. Six planes covered the advance in the air, and at about 11 a.m., the vanguard reached the vicinity of Wanquan County. Scouts reported that Wanquan County had become an empty city, undefended by the People's Liberation Army. Division 1O1 was the first to enter the city and ceased to be on standby. Subsequently, Commander Dong Qiwu and the personnel of the headquarters also drove into the city. In a large store, Dong summoned the commanders of the troops to study the battle plan of how to attack the PLA in Zhangjiakou. At this time, Wang Shuming, deputy commander of the Air Force (Chiang Kai-shek sent Wang Shuming, deputy commander of the Air Force, personally led the Air Force to support Fu's army in order to enable Fu Zuoyi to capture Zhangjiakou quickly) said to Dong Qiwu by wireless telephone in the air: "According to Wang's personal reconnaissance in the air, he saw that there was fire smoke rising into the air in Zhangjiakou, and on the road between Zhangjiakou and Xuanhua, he found that most of the People's Liberation Army was moving eastward, and judged that the People's Liberation Army in Zhangjiakou had retreated, and our army should move forward quickly to occupy Zhangjiakou, and the air force could cover the advance." At the same time, Wang Shuming also told Sun Lanfeng about the situation in the air. After Dong received this call, he thought that Wang was the deputy commander of the Air Force and that he must be reliable in his words. However, for the sake of prudence, it is still believed that it is not advisable to go straight ahead, and continue to be cautious in order to prevent accidents.

When all the troops heard about this situation, they all asked them to lead their troops into Zhangjiakou City first. After listening to the speeches and demands of the captains, Dong said: "Everyone's spirit is very good, but this operation must be fast, and we should use strong troops to enter Zhangshi in one fell swoop with a fighting attitude." Therefore, I think this task should be completed by the scholar brother to lead the mechanized troops with a part of the infantry! He then ordered the 92nd Regiment of the New 31st Division to send two battalions, led by the deputy regiment commander by car, to attack and advance to Zhangjiakou in a combat posture of rapid marching. Before leaving, Dong Qiwu said: "If the People's Liberation Army does not retreat, it will launch a fierce attack, first occupy Xiabao Fort, and cover the attack of the follow-up troops; If the People's Liberation Army has indeed withdrawn; The whole city is about to be occupied to welcome our army into the city. At this time, Division Commander An Chunshan also rushed to Jin and said: "We must occupy Xiabao first, otherwise, our army will have to work hard to attack the city!" The 1st Battalion of the 92nd Regiment served as a guard, and it couldn't be pulled out for a while, and the troops were not enough, so I would transfer another battalion from the 93rd Regiment to you, right? Jin said: "The task is urgent, the time is too late, if necessary, please send it again!" ”

At 2 p.m. on October 11, Jin Shuke led his mechanized troops, under the cover of six aircraft, to attack Zhangjiakou. Before setting out, the troops were briefed on some precautions related to the battle, and a reinforced infantry company was selected, five of which were driven by ten-wheeled trucks, and under the cover of four small tanks (as fast as cars), were the first to be dispatched for the search force. The rest of the troops, armed with guns, followed behind the tank convoy. When they arrived at the Wuhuali of Pingmen, the search unit reported that there was silence in Zhangjiakou City, and the People's Liberation Army had retreated. When a citizen who had just left the city asked him about the situation of the PLA, he said: "At about 4 o'clock last night, the PLA began to retreat, and the retreat was completely completed after dawn. Now that there is chaos in the city, and some bold citizens are about to snatch up all the things in the various offices, you should hurry into the city to maintain law and order. Then he asked: "In which direction did the People's Liberation Army withdraw?" He said: "Most of them are withdrawn in the southwest direction, and a small part is withdrawn in the direction of Xuanhua and Longguan." He also asked: "Are there any PLA troops nearby?" He said: "I don't know the details, I heard that there is still a People's Liberation Army on Ci'er Mountain, and how many people are there. ”
