The rockets and projectiles flew towards the Japanese machine-gun fire point, and without much effort, a "crooked-handled" machine gun and two machine gunners flew into the air. Without the suppression of machine guns, the soldiers of the first company stretched out their muzzles from their hidden places one after another, and used their superiority in firepower and accurate marksmanship to clear the Japanese troops blocking the attack on the Japanese position.

The width of the horizontal plane of the city wall on the left side is limited, and the Japanese army has a lot of troops, but there are only more than 20 people who can resist the attack, and the casualties of the first company after a few minutes of shooting are almost the same, and the first company tends to attack forward and advances dozens of meters. Seeing that there were still one or twenty meters to climb the left wall, the Japanese soldiers, under the command of a second lieutenant officer, rose up again.

At such a close distance, the two sides could be said to be close to each other, and the commander of a company shouted: "Drop a bomb!" and took the lead in throwing a grenade and bullet, and the soldiers of the first company also threw grenades and bullets at the Japanese army. The Japanese soldiers were also throwing at the soldiers of the company who rushed up*. In a continuous burst of explosions, fighters on both sides fell.

The commander of the first company was also slightly wounded, but knew that now was the time to fight hard, and if the attack failed, the troops behind would suffer a large number of casualties when they re-attacked. The commander of the first company raised the shell gun in his left hand, drew the broadsword behind his back with his right hand, and shouted, "Brothers, kill me!" With the company commander taking the lead, there were dozens of soldiers left in the company who could still fight, either holding rifles with bayonets on them, or drawing out the broadswords on their backs, shouting: "Kill!" and rushed towards the Japanese soldiers.

After the grenade and bullet exploded, the Japanese soldiers who came up from the city wall on the left still had more than a dozen who could fight, and when they saw the Chinese rushing up, they also raised their 38-type rifles with bayonets on them to meet them. Each soldier of the guard brigade was selected from the 90th Army, and he had a background in martial arts, and he fought with bayonets to win a stable victory over the Japanese army, and there were also more than a dozen soldiers who were good at using knives to dance with broadswords and kill them, and as soon as the two sides looked at each other, more than a dozen Japanese soldiers were quickly wiped out.

As soon as the remaining soldiers of the first company here stepped on the left city wall, a Japanese infantry squad came up with reinforcements, and two "crooked" machine guns fired cross-fired, and the officers and men of the first company were shot again and fell, and this time the company commander was also swept by the machine gun and fell on the sandbag. Several fighters who were lucky enough to escape the Japanese machine-gun fire were lying behind sandbags, unable to lift their heads suppressed by the machine guns.

Seeing that the Japanese army was about to recapture the lost position, a burst of gunfire rang out from behind a company of soldiers, and several light machine guns, as well as the dense fire of rushing, front, and semi-moving rifles hit the Japanese army one by one, and the remaining Japanese soldiers hurriedly lay on the ground. The surviving fighters of the first company looked back and saw that it was the commander of the second company who had come up with reinforcements from the second company. Ignoring the joy of escaping death, these soldiers raised their weapons together and shot at the Japanese soldiers.

The second company occupied the original position of the Japanese army, and when the two heavy machine guns were mounted on the position, the position was completely in the hands of the first battalion. Inoue Uefu saw that he had lost two infantry squads in a row, and also lost the cross-head position of the city wall on the left, and he was also nervous, and now he counted the soldiers who fled in front of him, and he could barely make up three more infantry squads, and the army of China had already occupied the cross-head position of the city wall on the left, and there was mortar cover, with the strength in his hands, it was unlikely that he wanted to recapture the lost position, so Inoue Icio ordered the soldiers to use the ground to defend on the spot.

As long as the left city wall is not lost, the Chinese army will not be able to attack the Guanlou, and as soon as the reinforcements sent by the captain arrive, they will be able to counterattack the Chinese army. Inoue Ueo was making wishful thinking, but the first battalion continued to attack the left wall. After Zhou Sheng, the commander of the first battalion, came to the occupied position, although he was also heartbroken by the loss of the first company, he understood that now was not the time to hold the position, and the first battalion had to continue to attack, take the left city wall, take the Guanlou, and take the entire Zhennan Pass.

Zhou Sheng observed the Japanese army in front of him and ordered the commander of the second company to lead the second company to continue the assault, and the third company behind used heavy machine guns to cover. When the commander of the second company received the order, he shouted without hesitation: "Second company, follow me!" and took the lead in jumping out of the formation and launching a surprise attack on the Japanese army. The width of the wall on the left is less than 20 meters, and there is basically no place to hide, and the two sides are fighting for their lives in this terrain.

Fortunately, the firepower of the first battalion was not a little stronger than that of the Japanese army, and the two heavy machine guns and several light machine guns fired cross-fire, and the Japanese soldiers who hit had nowhere to hide, so they could only lie on the ground tightly, and did not even dare to raise their heads. The 2nd Company charged while firing, and at the cost of dozens of casualties, rushed to the Japanese army. At this time, the machine guns could no longer shoot, and the officers and men of the second company drew their broadswords, picked up their bayonet rifles, and engaged in a white-knuckle battle with the Japanese soldiers who had just gotten up from the ground.

In this case, Zhou Sheng couldn't sit still, and he personally led the three companies to rush up. Hundreds of people were killed on the left wall, which was more than 200 meters long. There were 400 soldiers in the second and third companies of the first battalion, while the Japanese had only more than 200 men, and the second and third companies of the bayonet fought and won a firm victory over the Japanese army, and the battle ended after more than half an hour.

The first battalion completely annihilated a squadron of soldiers of the Japanese army, including Inoue Ue, captured the left city wall, and also opened the passage to the gate. The price paid by the same battalion was not small, the first company was basically wiped out, and the number of casualties in the second and third companies together exceeded 100 people. After Zhou Shengquan annihilated the Japanese army, he was rescuing the wounded, and Sun Linhai had already climbed the left city wall with the second and third battalions.

Inoue Ueo and his squadron were all killed, and when the news that the left wall had been captured by the Shina army was reported to Ono Yuo Nakasa, Ono turned pale. He gathered all the strength of his brigade and said to them: "You are all warriors of the Great Japanese Empire, and now is the time for you to be loyal to the Great Japanese Empire and His Majesty the Emperor! I will lead you to fight to the death with the Chinese army! The Great Japanese Imperial Army will win!"

The morale of the soldiers was boosted, and everyone shouted, "Victory!" and then Ono Yuo drew his command knife and pointed in the direction of the left wall, shouting, "Kill, give!" and took the lead in rushing towards the left wall. On the left side of the city wall, Sun Linhai was about to command the second battalion to continue the attack on Guanlou, but he saw hundreds of Japanese soldiers shouting slogans and charging towards his side.

Sun Linhai first asked the second battalion not to attack in a hurry, set up a few heavy machine guns on the city wall, and then sneered at Wu Dashan, the commander of the second battalion: "Little Japan really doesn't know whether to live or die, if these hundreds of people defend the gate, we are afraid that it will be a little harder for us to attack, and now that they have charged first, let them taste the taste of heavy machine guns! Heavy machine guns fire!"

Several heavy machine guns were ordered, the muzzles of the guns spit out flames at the same time, and the bullets flew towards the charging Japanese troops like a rainstorm, the Japanese bushido spirit still could not stop the metal bullets, and the charging Japanese soldiers fell on the way one by one, and ten minutes later, there was no Japanese soldier who could stand on the opposite side of the second battalion, and several heavy machine guns stopped firing.

After Sun Linhai gave the order of the second battalion to advance to Guansu and clear the remnants of the enemy, he turned around and came to Tangshan Leopard and reported loudly: "Report to the brigade commander, the third regiment has captured Guanlou and is clearing the remnants of the enemy and cleaning up the battlefield." Tangshan Leopard looked at his watch, it was already eleven o'clock in the morning, Tangshan Leopard patted Sun Linhai on the shoulder and said: "Good job, take Zhennan Pass so quickly, the three regiments should be a big achievement." After speaking, he turned to Li Li, the commander of the second regiment next to him, and said: "Li Li, your second regiment will immediately take up the defense task of Zhennanguan to prevent the Japanese army from coming to reinforce Zhennanguan." Li Lili replied: "Yes, brigade!"

Li Li sent the first battalion to the Guanlou fortification, the second battalion to the right city wall fortification, the third battalion to the left city wall fortification, the three battalions just arrived at their respective positions, the first battalion commander Wei Song sent people to report that a large number of Japanese troops were found three kilometers away from the Guanlou, and it was seen that its purpose was Zhennan Pass. Li Li immediately reported to Tangshan Leopard, and Tangshan Leopard was also taken aback, and said to Li Li: "It's so dangerous, if you don't take Zhennan Pass before the arrival of this Japanese army, it will be troublesome." Now let this little Japan taste the power of our guard brigade again! Li Li, organize the defense immediately, and I will hand over all the mortars to you to command. ”

Li Li led the order to the city wall of Guanlou, and the mortars he brought also went to the city wall. Li Li began to arrange the defense, the Guanlou city wall is facing the Guanxia road, which is the main position, and all the battlements of the women's wall are arranged with machine guns. Eighteen 82-caliber mortars were arranged on the wall of the gate, and six 120-caliber heavy mortars and ten small-caliber mortars were arranged on each side of the wall.

At this time, the third regiment had almost finished cleaning up the battlefield and cleared the remnants of the enemy. On the one hand, Sun Linhai sent people to send the wounded to the occupied warehouse for treatment, and on the other hand, he sent people to take over the military supplies left by the Japanese army in Zhennan Pass, and at the same time sealed the two gates under the gate with sacks, cutting off the road through Zhennan Pass. This also meant that tens of thousands of horses and horses of the Japanese 16th Army that had entered China were blocked on the 18-kilometer road from Pingxiang City to Zhennanguan.

It was an infantry brigade of the Japanese army that came to reinforce Zhennan Pass, and the captain of the team, Yamamoto Takao, saw from afar that the gate of Zhennan Pass was closed, and the blue sky and white sun flag of the people of Zhenna were also replaced on the upper floors of the pass, and he immediately understood that it was not good, and Zhennan Pass had fallen into the hands of the Chinese army. Takao Yamamoto immediately telegraphed his report to Wing Captain Yusa Yoshimatsu.

When Yoshimatsu Yusan heard that Yuo Ono's infantry brigade was guarding Zhennan Pass, and that the whole army was wiped out before it even lasted a morning, he couldn't help but scold angrily: "Yaga! Ono, this idiot, the face of the Imperial Japanese Army has been completely lost to him!" After sending out a fire, Yoshimatsu Yusan Sanzuo thought of the consequences of the loss of Zhennan Pass, and the brigade commander told him that his Shina army was on an all-out counteroffensive, and his heart couldn't help but feel cold.

Yoshimatsu Yu Sansa immediately called back Yamamoto Takao Nakasa, ordering Yamamoto Tadao Nakasa to recapture Zhennan Pass at all costs. After sending a telegram back to Yamamoto Takao, Yoshimatsu was worried that Yamamoto Takao's infantry brigade was insufficient, so he sent a telegram to the brigade commander, Major General Matsui Kiichiro, to report the loss of Zhennan Pass.
