In December 1948, the Battle of Pingjin had developed in full accordance with the strategic intentions of our army, and Fu Zuoyi's 35th Army was trapped in the new security. New Baoan, located on the railway line between Shacheng and Xiahuayuan, south of the Dayang River, north of Babao Mountain, although the area is only 1 square kilometer, the defender Gyeonggi, has always been a must for soldiers. Although the new security town is small, its walls are extremely strong, all the surface is made of green bricks, the upper layer of the interior is thick, the walls are about 9 meters high, the top width is 3 meters, and the fortifications built by the enemy are everywhere so that they can concentrate their fire. The new security guards have three gates in the east, west and south, and there has been no north gate to resist foreign invasion. The city is an east-west, north-south cross street. The most prominent building of the new security is a bell tower located in the center of the city, which is also the commanding height of the whole city, and there is a plaque on the bell tower, which reads four large characters on the key of the lock, which shows the importance of its geographical location, and the command post of the enemy army is located in a compound in the northwest corner of the city not far from the Drum Tower.
On the day of being trapped in the new security guard, Guo Jingyun led his men to the commanding heights of the whole city, and at this time, he was still so proud. In order to stabilize the mood of his subordinates, he boasted: Our Thirty-fifth Army grew up eating steel and throat iron, and defending the city is our housekeeping skill. When Zhifeng united with Yan Xishan to fight against Feng Yuxiang, we defended Tianzhen, during the Northern Expedition we defended Zhuozhou, during the War of Resistance We defended Taiyuan, and during the suppression of bandits, we defended Guisui and Baotou. Except for Taiyuan, every time we won the battle, now take a new security guard, what is the point! Guarantee that our Thirty-fifth Army will return safely to Beiping within three days.
At this time, Guo Jingyun was still so overwhelmed, he only thought that the new security guard was a place to stand, and he would not wait for death here. His men, on the other hand, were emotionally unstable, and they only felt that the Thirty-fifth Army had slipped into the big fishing net of the communist army, just waiting for the communist army to come and collect the net. Guo Jingyun did not have these thoughts in his mind. For two consecutive days, Guo Jingyun led his troops to break through, but all failed, at this time Guo Jingyun began to waver, he was a little dazed, was it true that the resounding ace army of the Thirty-fifth Army had really become a turtle in an urn? At this moment, he thought of Beiping and asked Fu Zuoyi for help. He understood that Fu Zuoyi would certainly not abandon the Thirty-fifth Army he had started, and if nothing else, just by relying on the more than 400 "Dadaoji", Fu Zuoyi would also find a way to save him. Sure enough, Fu Zuoyi urgently ordered An Chunshan to lead the 10th and 4th Armies to meet him. An Chunshan received the order, although he realized that this task was more fierce and less auspicious, and perhaps he would be doomed.
But he thought more of the trust of Commander-in-Chief Fu in danger. So he began to prepare without stopping. He immediately decided to let the deputy commander Wang Fazi lead two divisions to send troops to the new security. Wang Fazi and Guo Jingyun agreed that at dawn the next day, the 104th Army would launch an attack to attack the horse circle southeast of xinbao, and the thirty-fifth army would go out of the city to coordinate the battle, and then the two armies would meet in the horse circle to return to Beiping. At dawn the next day, Wang Fazi concentrated the strength of 4 regiments, under the cover of 12 aircraft, and fired fiercely at the established target, and the Rehe Independent Cavalry Brigade of the North China Military Region stationed in this area made a tenacious counterattack against the enemy, causing the enemy to leave behind the corpses scattered all over the mountains, but finally lost because of the outnumbered.
Wang Fazi came to the horse circle, and he hurriedly called out to Guo Jingyun to let him break through, but Guo Jingyun, the general who was always victorious, did not know whether he was posing a frame or had misunderstood something, was unwilling or afraid to go out of the city, and insisted that the 104th Army enter the city to pick him up. Just as these two units wanted me to go out of the city to meet you, and I wanted you to enter the city to protect each other, the fourth column of the Northeast Field Army annihilated another reinforcement of the enemy Sixteenth Army in Kangzhuang, occupying the line of Kangzhuang, Bundao, and Qinglong Bridge, and the enemy's 104th Army was heavily encircled. At 16:00 on the 10th, the enemy's 10th and 4th Armies broke through and fled south, and were pursued by our 4th column and 11th column. At 23:00 on the same day, the 4th column and the 11th column grabbed the rear of the enemy's 27th Division, and the vanguard troops inserted into the enemy's headquarters, disrupting the enemy's command system. At this time, the enemy had scattered all over the mountains and collapsed into an army.
On the morning of the 11th, most of the 10th and 4th Armies were annihilated. An Chunshan, the commander of the 104th Army, secretly changed into a soldier's uniform the night before, and after being captured, he falsely claimed that there was an 80-year-old mother in need of care, so he was released. On the same day, he returned to the Headquarters of the "Suppression General" in North China to report to Fu Zuoyi that he had been mourned. At this time, the Pingsui Line was completely cut off, the enemy's Thirty-fifth Army had no troops to the west, the east was powerless, and the new security became an isolated island, and the Thirty-fifth Army fell into a desperate situation.
