At 7 p.m. on October 19, three red flares were lifted into the air, and the Katyusha artillery began to roar; The enemy's fortifications on the northern hill of the 537.7 heights were quickly lifted into the sky, and the four tanks left by the Korean army on the positions during the day to prepare for the night counterattack of the volunteers were quickly destroyed by Katyusha's shells. The huge explosion of the tank broke the mentality of many South Korean soldiers, and some South Korean officers and soldiers even shot themselves in the leg first......

This time, the 15th Army concentrated a Katyusha rocket artillery regiment and 44 large-caliber artillery pieces to carry out a 30-minute fierce artillery bombardment on the 537.7 Heights North Mountain, and almost all the fortifications, bunkers, and firepower points of the South Korean Army on the 537.7 Heights North Hill were destroyed; The remaining few bunkers and firing points were all knocked out by the counterattacking forces using mortars and rocket launchers, and two companies of the Volunteer Army and one engineer platoon in charge of this counterattack annihilated four companies on the ROK defensive positions in only 20 minutes, restoring all surface positions (the easy attack and difficult defense of Beishan on the 537.7 high ground is also an important reason). After restoring the surface positions, the counterattacking troops quickly cleaned up the battlefield and moved to the defense in accordance with the battle plan; Actively prepare for the enemy's counterattack during the day on the 20th.

At the same time as the counterattack on the 537.7 heights on the north mountain began, the counterattack on the 597.9 heights also began; dozens of Katyusha rockets and 40 large-caliber artillery pieces opened fire at the same time, and many of the US fortifications were wiped out in an instant. "Comrades, Katyusha rocket artillery made immortal contributions during the anti-fascist war! Katyusha rocket artillery is now a sharp weapon for our army to suppress US artillery. Li Wenwu said to the volunteer soldiers who were waiting for a counterattack in the tunnel. There are almost not many enemy fortifications and firing points left this time, right? A young soldier asked, "Most of them will be destroyed by our artillery fire, but some of the bunkers may not; Moreover, the enemy has occupied surface positions many times and is already familiar with our positions, so it is very likely that some of the firing points will be repaired in the dead corners of artillery fire; Tonight's counterattack must be prepared to overcome major difficulties. Li Wenwu replied and encouraged the fighters to;" No matter how many difficulties we have, we will overcome them, and tonight we must all restore the surface positions! Zhao Lianfa said firmly. At this time, our artillery fire began to extend, and once again suppressed the American artillery fire; "Comrades, prepare to charge; Cooperate with the brother troops to retake the surface position! Zhao Lianfa ordered the officers and men of the Volunteer Army to resolutely rush out of the tunnel and devote themselves to the counterattack operation according to the established battle plan......

The first reinforced company cooperated with the 8th Company of the 134th Regiment to launch a counterattack on the No. 1 position, and the U.S. firepower points and bunkers on the No. 1 position were basically wiped out under the artillery fire of the volunteers; There was only one bunker and one firing point left, and the bunker of the Eighth Company was exposed when it feint to attack the enemy, and the bunker was isolated and not too biased; The 8th Company used two mortars to solve the enemy's fire points and bunkers, and the 8th Company rushed into the No. 1 position and captured the No. 1 position after about 10 minutes of short contact with the enemy; Before a flamethrower at the enemy's No. 1 position could react, he was shot dead by Zhang Dongfang, who was operating with the Eighth Company.

The 8th Company and the 1st Reinforced Company, which had captured Position 1, immediately launched a charge towards the main peak of Position 3, when the enemy's bunkers on the east and west sides of the position suddenly opened fire; The Volunteer assault unit was pressed by fire on the offensive path. The Eighth Company used the last two small shells to solve the enemy's bunker on the west side, and the bunker on the east side was still spewing tongues of fire..... "Zhang Dongfang, Lai Fajun cover, blast a group of preparations!" Zhao Lianfa, who was in charge of unified command, made a decision immediately. As several grenades were thrown, several fighters rushed to the designated battle positions under the cover of the smoke screen of the grenade explosion; When machine gunner Lai Fajun and sharpshooter Zhang Dong fired at the enemy's bunker, the two demomen rushed towards the enemy's bunker with one explosive bag and the other with a blaster canister at the moment when the enemy's fire stopped. However, the demolition team rushed to a distance of about 50 meters from the enemy's bunker and fell under the fire of the bunker, and the machine gunner Lai Fajun who was in charge of covering was also slightly injured (in fact, Lai Fajun and sharpshooter Zhang Dongfang fired at least 3 bullets into the enemy's bunker during the cover, causing one enemy to be killed and one wounded, but there were 8 enemies in the bunker...... After the defeat of the second group, the second demolition group once again blasted the enemy's bunker, and Zhang Dongfang and Lai Fajun moved forward for a distance at the same time to continue shooting and covering; The second demolition group also failed to blast successfully. "Comrade Zhang Dongfang, this time you cover me to blow it up; If I fail too, the enemy's bunker will be handed over to you! Lai Fajun picked up two grenades and rushed out without hesitation, Zhang Dongfang took his machine gun and fired fiercely at the firing port of the enemy's bunker......

Under the cover of Zhang Dongfang's accurate shooting, Lai Fajun's army sometimes crawled forward, sometimes rushed forward; When he reached about 2 meters away from the enemy's bunker, he had already been wounded in many places, Lai Fajun rested a little and looked back at his comrades; "Comrades, for the sake of the Motherland, forward!" With the last of his strength, Lai Fajun jumped up with two grenades and perished with the enemy's bunker! "Rush! Avenge the sacrifices of your comrades!" The 8th Company and the 1st Reinforced Company regained the main peak of the No. 3 position in one fell swoop.

After recovering the main peak of Position No. 3, the 8th Company and the 1st Reinforced Company quickly launched an attack on Position 9, and the attack began relatively smoothly, quickly knocking out the enemy's remaining fortifications and firing points or successfully blasting them. The attack was halted by dense enemy fire during the attack on the enemy's main bunker, and the attack was temporarily halted. "Why didn't the artillery fire of such a large main bunker knock it out?" A platoon commander of the Eighth Company asked puzzledly, "If you take a closer look, this bunker is made of a boulder hollowed out by the U.S. military, and the location happens to be in the dead end of our artillery; So it's left. "Zhao Lianfa and the commander of the eighth company said;" Let's prepare for the blasting, Comrade Zhang Dongfang will take two machine gunners to prepare for cover, and the first and second groups of blasting will be prepared! "Zhao Lianfa and the commander of the eighth company ordered. As the order was given, the three fighters of the demolition team immediately rushed to the enemy's bunker, and Zhang Dongfang and two machine gunners simultaneously fired in the direction of the enemy's bunker; Zhang Dongfang used the Water Lianzhu rifle to aim at the firing hole of the enemy bunker and fired continuously, and three bullets were fired into the firing port of the enemy bunker; The American soldiers inside had already been killed and wounded, and the other American soldiers immediately filled their positions and continued to shoot. Under the tongue of fire of the American army, two fighters had already fallen, and only the Miao warrior Long Shichang reached about 5 meters from the enemy's bunker; Suddenly, a shell fell and exploded next to Long Shichang, and the left leg of the Miao warrior Long Shichang was blown off; Long Shichang stubbornly crawled towards the bunker, and finally climbed in front of the bunker under the cover of his comrades; Long Shichang inserted the blaster through the firing hole of the enemy bunker, but was immediately pushed out by the enemy; Long Shichang pushed the blaster in again and firmly resisted the blaster with his chest, and with a loud bang, the enemy's bunker disappeared, and the people's heroes turned into gold stars and dissipated in the air. The officers and men of the Volunteer Army shouted slogans and rushed to the No. 9 position, eliminating all the American troops on the position, and recovering the No. 9 position in one fell swoop. "It's almost over our side, Zhang Dongfang, you take a squad to support the Sixth Company!" Zhao Lianfa gave an order to Zhang Dongfang. "Yes! Class 9 with me! Zhang Dongfang took the ninth squad to march sharply in the direction of another counterattack to reinforce the army.....
