"Fat Wu, how's it going?" Bangs ran to the command post of Wu Fatty! "it, I can't stand it, division commander, this time it's hard to gnaw, the attacking force has suffered more than 2,000 casualties, but it still can't be attacked, this bunker and firepower are denser and stronger than they were in Songshan!" Fat Wu looked at bangs with blood-red eyes. "Tell me about the situation!" Bangs asked. Wu Fatzi roughly explained his situation, the target of the southern attack was the Dongshan position, the Dongshan area is the natural barrier of Taiyuan, its main peak Luoshan is 500 meters higher than Taiyuan City, overlooking the entire urban area. Yan Xishan is well aware of the importance of Dongshan to Taiyuan, and he once said: "Once Dongshan is lost, Taiyuan will be lost." "Yan army in the Dongshan defense line carefully built all kinds of pillboxes more than 3,000, located at the top of the west foot of the Dongshan Mountain, the cow camel village, Xiaoyaotou, Naoma, the mountain is the four major fortresses of the Dongshan defense line, up to eight kilometers, 3 to 5 kilometers away from the city, 300 meters higher than Taiyuan City, can overlook the control of the city wall, the north of the city industrial zone and the north of the city airport. The four fortresses are independent and interconnected, consisting of 3 to 15 small hills or villages to form group positions, dozens of pillboxes to form defensive fortresses, supplemented by field fortifications, deer barricades, barbed wire, splitting slopes and tunnels, and auxiliary defenses ranging from three to thirteen. Because of this, Yan Xishan boasted that "the four key points in the east of the city are the fortress in the fortress and the fort in the fortress, which is enough to reach 100,000 elite soldiers", and "the Communist Party does not dare to fight at all, and it has no strength to defeat it." ”

After Wu Fatzi followed the troops to the attack position, the first target was the cow camel village! Niuhuo Village is composed of three major group positions to form a defensive ring, ten main pillboxes are the position support points, the terrain is narrow, the mountain peaks are stacked, and the slopes are precipice, it is the main position on the defense line of the Yan Army's Dongshan, here is the seventh column of the Northwest Field Army is responsible for attacking, and the main task of Wu Fatzi is to provide fire cover and support for the seventh column! Under the leadership of underground party members, the main force of the seventh column marched more than 20 kilometers and penetrated deep into the enemy's defensive circle from a secret path, and with the support of Wu Fatzi's artillery fire in the front, it wedged into the cow camel village to launch a surprise attack, and captured other positions except the main position Miaojie before dawn the next day. Just as the position was handed over to the follow-up 19th Regiment, the two sides did not take over tightly, and the 21st Regiment withdrew prematurely, resulting in part of the position being reoccupied by the enemy. Before Wu Fatzi could replenish his ammunition, the Yan army continuously organized counterattacks under the cover of artillery fire and aircraft, charged more than a dozen times a day, and fired "biphenyl" gas bombs, Wu Fatzi's artillery were all hit, and dozens of artillerymen were poisoned!

Before the troops of Niu Huozhai could recover their breath, a regiment of the 30th Army, the most elite of the Yan Army, and the 10th Corps with the Japanese as the backbone launched another fierce attack, counterattacking seven times in a row, four enemy planes took turns strafing and bombing, concentrated artillery bombardment for more than three hours, more than 10,000 rounds of bombs fell on the position, the mountain was deformed, except for the reinforced concrete fortress, all the ground fortifications were destroyed, the scorched earth was up to two feet thick, shrapnel debris was everywhere, and the soldiers who held the blasting mission were in the process of crawling forward. The sharp shrapnel in the floating soil cut through the cotton clothes and left bloody wounds on the soldiers' bodies, and some of the soldiers who fell into the floating soil still stood upright with their guns in their hands until they died, and they did not blink to death, and the mouth of the tunnel of the command post of the 2nd Battalion of the 19th Regiment was blown up by enemy planes, and the commander of the battalion headquarters was trapped in the underground tunnels for a time. After four days of brutal slaughter, both the enemy and us suffered heavy casualties, and in the afternoon of the same day, the People's Liberation Army abandoned the cattle and camel village. In the process of retreating, due to lax air surveillance, Wu Fatzi's artillery was attacked by the air force, more than a dozen guns were blown up, and the entire operation to attack Dongshan was a complete failure! At the same time that the Niuhuo Village was abandoned, several other columns also made little progress in the offensive, and the Taiyuan Front Committee decided to reorganize the columns and concentrate their forces and firepower to storm the four major fortresses.

"Now Commander-in-Chief Xu has ordered the columns to reorganize and concentrate their forces and firepower to storm the four major fortresses! My artillery is on the main fire duty! Wu Fatzi said: "That's why you came to support me!" "Humph! The four fortresses, in my opinion, are four piles of tofu, if you hit such a fixed target and are still so sloppy, I will not do it! Liu Hai said unconvinced, "I'll teach you a trick, the best way in this case is to attack indiscriminately, and command your heavy artillery to bombard me inch by inch!" "Wouldn't I do such a simple move?" I've tried, but you don't know how perverted Yan Laoxi's bunker is, most of the time it's blown up by cannonballs but can't be blown up! "Wu Fatzi is complaining!" Call you a fool! Liu Hai said, "Push the cannon up, shoot directly where there is firepower, even if your heavy artillery can't blow up the opponent's bunker, the earthquake can also shock the living people inside to death!" Then ask the attacking force to organize hundreds of commandos, use the artillery to aim directly at the next few minutes, use * to carry out blasting, no matter how hard the pillbox is, you have to remember that the attack is to cooperate with the artillery, can you occupy the position with the artillery alone? "I see, division commander, I'll notify the attacking troops immediately!"

Another attack was launched, four columns and 12 divisions launched an attack at the same time, and the artillery that provided fire cover for it was not only Liu Hai's artillery division, but also the artillery directly under each column, after the attack order was issued, the four major fortresses were ignited at the same time, and both sides of the enemy and us put the main force into this position that was no more than eight kilometers long, and there were as many as 700 artillery pieces on both sides participating in the battle, and the battle was fierce and unprecedented for the Taiyuan Campaign. As soon as the attack began, the mid-lane attack column was counterattacked to the death by the opponent's 10th Brigade! This 10th Corps is composed of Japanese, all of whom are carefully selected by Yan Xishan and composed of junior officers, all of whom are the elite of the Japanese Army! "Fuck! Do you still want to make a fuss about this? Tell the ghost artillery to draw out a battalion of artillery power and hit me hard! Bangs said hatefully. Division commander, the 4th Column and 7th Division require our artillery support! The staff officer came over and said. I saw them over there, you don't need heavy artillery support, you can organize a demolition team and a mortar sortie! Tell the ghost artillery to block the retreat of the enemy's counterattack force with all his might, and this tenth brigade has actually come out, so he can't be allowed to go back! "Bangs keep giving orders!" Tell Wu Fatzi to draw out a company of heavy artillery and participate in the attack on Ma Zhai! Be sure to destroy the central bunker where! ”

After the fight, Liu Hai knew that he had made a little mistake, he had miscalculated the intensity of the battle, the artillery kept bombarding, the commanders of several columns were desperate for their lives, the casualties of each division and battalion were very large, and the soldiers of the Jin army were indeed not bad, and they fought back desperately under the leadership of the commander, and the Japanese were also like crazy, and took out the strength of the Great East Asian Holy War that year, and fought to the death with the PLA! In the past few days, Liu Hai has been going crazy, the ghost cannon and Wu Fatzi are carrying the cannonballs and their own soldier cannons so that the barrels of the cannons are about to catch fire, and the ghost cannons take the lead in cooling the cannons with water cloths, and the shells of the cannonballs are full of a ditch! The support points and high ground on all fronts were repeatedly contested, and every attack and counterattack was heavily wounded! After a counterattack, most of the Jin army was killed and wounded, but it also beat the People's Liberation Army in one time! The victory was temporary, and within a few minutes, the coverage of the ghost artillery arrived, and the few remaining troops barely had time to form a group, they were killed and wounded by the ghost artillery, and the follow-up counterattack troops once again rushed up and occupied the position! The two sides fought repeatedly for 19 days on the 8-kilometer position in Dongshan, and in these 19 days, the four columns took turns to fight, some regiments were wiped out, and some divisions had been beaten into empty shells, but Dongshan still had not been captured, and the positions of the two sides were staggered, and the victory and defeat were inseparable!

In these nineteen days of bloody battles, the two sides suffered heavy losses, the PLA lost more than 10,000 people, 14,000 wounded, the four columns almost lost their combat effectiveness, and the Taiyuan defenders also lost nearly a quarter of their troops in the fierce battle, but Dongshan is too important for both sides to ignore the place! Under the heavy casualties, the commander-in-chief of the People's Liberation Army Xu lamented the bravery and fearlessness of the Jin army, and thought that most of these Jin troops were anti-Japanese troops in the eight-year bloody battle, and the commander-in-chief Xu was also heartbroken! However, the battle was not over yet, and new troops were once again drawn from the Northwest Field Army and the North China Field Army to enrich the attacking troops! The 1st, 2nd, and 3rd Corps of the North China Military Region were renamed the 18th Corps, the 19th and 20th Corps, and the 10th Column of the Northwest Field Army. On the orders of the Central Military Commission of the Communist Party of China, the 11th Corps of the Sixth Corps of the North China Military Region, the 11th Corps of the Fourth Field Army, and one artillery division of the North China Military Region each set out for the Taiyuan front to attack Taiyuan together with the original attacking units and other units, thus increasing the total strength of the People's Liberation Army on the Taiyuan front to more than 320,000 men, giving it an absolute advantage over the defenders. The Central Military Commission of the Communist Party of China decided to form the Taiyuan Front General Committee of the CPC with Xu Xiangqian as secretary and the Taiyuan Front Command with Xu Xiangqian as commander and political commissar to unify the command of the troops participating in the war.

After the previous stage of fighting, together with the losses during the siege, the Taiyuan Kuomintang army has consumed more than 40,000 troops. However, Yan Xishan, who was already in a desperate situation, not only rejected the advice of the People's Liberation Army to liberate Taiyuan peacefully, but instead recruited troops to expand the army and organized the "Divine Brave Division", "Iron Blood Division", and "Steadfast Loyal Division". The 83rd Division was airlifted from Yulin to Taiyuan, so that the Taiyuan defenders still maintained the strength of six corps, together with the irregular army, a total of about 70,000 people, to form the first corps headquarters. Its deployment was as follows: 12 divisions to defend the periphery of Taiyuan, two divisions to defend the urban area, and the rest of the troops as mobility, but the combat effectiveness was very weak. In fact, at this time, Yan Xishan was desperate for the battle situation in Taiyuan, so escaping Taiyuan became his most important thing! However, when the 83rd Division was airlifted, it was found that the airfield had been controlled by enemy artillery fire, in order to be able to escape smoothly, Yan Xishan gathered two divisions and three regiments of artillery fire, and began to attack the mountain bag position held by Wang Jinshan.
