Although Jin Zige is only the commander of the colonel, the armored regiment is a unit directly under the division, and Li Yuanhong has a high opinion of these regiments directly under him, so although Huanggang is a major general and brigade commander, he is also very polite to Jin Zige, plus in the street battle, with the cooperation and support of armored vehicles, the difficulty of the attack will be reduced a lot, and the casualties of the soldiers can also be reduced.

Jin Zige was not arrogant as the commander of his own armored regiment, and he put himself in the right position. In the face of Huang Gang's polite greeting, he did not hold it up, but said: "Brigade Commander Huang, our armored vehicles are just to cooperate with your attack, they are all a family, don't say polite words, if you have any tasks, please give them, I promise to complete the tasks!"

Huang Gang nodded and said, "Okay! Captain Jin, I'll just say it directly." Look at the three-story building in front, dozens of Japanese soldiers used it as a stronghold, and because the fire was too fierce, we rushed several times without success. Now I hope that Commander Kim will use the vehicle-mounted artillery on the armored car to bombard the machine-gun fire point at the window upstairs to cover the infantry attack, and I will let the mortar cover your movements. ”

Jin Zige used a telescope to observe the three-story foreign arm and replied: "No problem, the artillery fire on our car can't destroy the entire building, and it's still no problem to knock out the machine gun fire point in the window." After saying that, he turned around and got into the car, used the on-board radio to communicate with another heavy armored car, and as soon as he put on the accelerator, he rushed down the street to the western-style building.

This German-made eight-wheeled heavy armored vehicle, the strength is still very strong, although it can not withstand the bombardment of artillery, but the Japanese light and heavy machine guns can not beat it, plus it is equipped with a 20 mm caliber gun and two MG34 heavy machine guns to ensure sufficient firepower output, if on the battlefield, it meets the Japanese light tank, the battle will never be at a disadvantage.

Two armored vehicles approached the building one after the other, and behind them was an assault platoon selected by Zheng Daodong. Although the sky was dark, the Japanese still noticed the two armored vehicles that came by surprise. The Japanese troops in the building were also ready to use mortars on the roof of the building to deal with the two tanks, but as soon as the two groups of artillery with the mortars went to the roof, Zheng Daodong commanded the mortars in the regiment and hit the shells on the roof.

In the explosion, several Japanese soldiers fell on the roof of the building, and the remaining Japanese soldiers fled back to the building in disarray. At this time, all the Japanese machine-gun fire points on the windows of the building were fired, and the armor on the armored vehicles hit by bullets clanged indiscriminately. Seeing that the distance was enough, Kaneko Ge first ordered his armored car to open fire, and a shell went straight to the machine gun fire point in a window on the second floor.

With the sound of the explosion, the two Japanese soldiers were pushed out of the window by the air wave and fell downstairs screaming, and the machine gun was completely destroyed. Then the guns on the two armored vehicles were called at each machine gun fire point in turn, and the effort was not great, and all the more than ten machine gun fire points on the upper floor were dumbfired. After shelling the door of the building with artillery fire, the two armored vehicles continued to suppress the Japanese troops inside the building with heavy machine guns.

Taking advantage of the fact that the Japanese firepower was completely suppressed, the assault platoon decisively launched a surprise attack, and without any casualties, it broke through the bombed gate into the building. Immediately after that, the sound of rushing and sharp guns sounded in the building, and from time to time there would be an explosion of grenades and bullets. Fifteen minutes later, the assault platoon completely cleared the Japanese troops from the building and occupied the Japanese stronghold.

After successfully completing the task, Jin Zige said goodbye to Huanggang, and there were other places that needed the support of armored vehicles. After Huang Gang expressed his gratitude to Jin Zige, he commanded the 571st Regiment to continue to break inside. The situation of the 569th Regiment and the 570th Regiment was similar to that of the 571st Regiment, and they all encountered stubborn resistance from the Japanese army. Although it was dark, the city of Lang Son was bustling with fire, with the sound of guns and explosions, the flash of bullets across the night sky, the flashes of explosions everywhere, and the light of fires burning in all directions illuminating the night.

Together, the three regiments exceeded 5,000 troops, and they had an absolute superiority in weapons, and although the Japanese army was no less numerous than the Chinese army and had a favorable position, it still could not withstand the attack of the three regiments and retreated one after another. The battle lasted all night, and by the time the sky was slightly bright, the three regiments had advanced a few hundred meters each, and the Japanese army was further compressed into a narrow area of more than 500 meters long and 300 meters wide.

There were still more than 2,000 Japanese troops guarding the last line of defense, and the officers and men of the three regiments were very tired after a day and a night of fierce fighting. After dawn, Huang Gang gave an order, and the 572nd Regiment, which had been recuperating for a long time, drove into Langshan City, taking the place of the 571st Regiment's attack position, and at the same time, the armored brigade also concentrated eight heavy armored vehicles, and fifteen light armored vehicles were beside the 572nd Regiment.

Huanggang was preparing to take the attack direction of the 572nd Regiment as the main direction of attack and launch a fatal blow against the Japanese army. Opposite the 572nd Regiment, there were about two infantry squadrons of Japanese troops, guarding a street about 300 meters long and about 10 meters wide, and at the end of the street was the original Lang Son City Government Building, which is now the headquarters of the 30th Brigade and Regiment of the Independent Mixed Brigade.

On the 300-meter street, the Japanese army built ten bunkers before and after, as well as a position composed of five sandbags, and the rooms on both sides also appeared from time to time Japanese soldiers and some firing points. After observing the situation of the Japanese army, Huanggang ordered the mortar group organized behind him to open fire first. The mortar group has thirty mortars of large and small calibers, which is all the mortars that can be gathered in a short time.

The mortar salvo covered the first line of Japanese defense and two bunkers in the street, and five minutes later, the mortar fire began to extend, and the sound of artillery was heard from a distance, followed by a volley of shells flying towards the mortar position. The sudden artillery counterattack of the Japanese army made Huang Gang's face change greatly, and he just shouted: "Japanese artillery bombardment, hidden!" This group of shells fell.

It turned out that at this time, seeing that Langshan Castle was about to be unable to hold on, Major General Takahashi Masao could no longer bear it anymore, and ordered the hidden mountain artillery brigade to fire back, and the target was the mortar group that was firing artillery. In just 10 minutes, 30 mortars blew up more than 20 of them, and the artillery suffered heavy casualties.

Huang Gang watched as the artillery positions became hell, full of stumps and broken arms of soldiers, and mutilated corpses that had fallen. Looking at everything in front of him, Huang Gang and all the warriors' eyes were red. Just when Li Jieli, the commander of the 572nd Regiment, scolded: "I am the eighth generation ancestor of Japan!" and then when he was about to order the whole regiment to attack, Huang Gang suppressed his grief and indignation, forcibly calmed himself down, and stopped Li Jieli.

Huanggang knew that if he did not get rid of the Japanese artillery, he would launch a charge, and in this narrow terrain, more soldiers and chariots would be destroyed under the Japanese guns. Huang Gang immediately reported the situation that the Japanese army still had a large number of artillery to Li Yuanhong. Li Yuanhong was also taken aback when he heard it, he didn't expect that the Japanese army still had this hand, and he didn't let the artillery return fire until now.

Li Yuanhong thought for a while, waved his hand, and ordered the heavy artillery regiment to send the 75-caliber field artillery battalion into the city, and it was necessary to knock out the Japanese artillery position. Tang Weiren, commander of the heavy artillery regiment, received an order from the division commander and immediately personally led the 24 field guns of the 75-caliber field artillery battalion into the city. When the field artillery battalion selected the ground type behind the 572nd Regiment and spread out its position, the regiment commander Tang Weiren immediately came to Huanggang to receive the task.

Knowing that the field artillery battalion was in place, Huanggang called Li Jieli and asked Li Jieli to send a company to launch a feint attack on the Japanese position, so as to attract the Japanese to open fire again. Jin Zige interjected beside him: "Brigade Commander Huang, if you want to attract the Japanese to open fire, the infantry alone may not be enough, I ask to send two more armored vehicles to go up together." Huang Gang said: "Commander Jin, your armored car can't withstand the Japanese artillery fire, this attack, the Japanese artillery fire is coming, and the armored car on it is very dangerous!"

Jin Zige replied: "As long as we can attract Japanese artillery fire and let our artillery destroy the Japanese artillery, it is worth sacrificing these two armored vehicles, all for victory!" Faced with Jin Zige's words, Huang Gang hesitated for a long time before agreeing to his request. Twenty minutes later, two heavy armored vehicles opened the way with vehicle-mounted artillery and heavy machine guns, and a company of infantry followed behind the armored bodies and launched a surprise attack on the Japanese lines.

The first line of defense of the Japanese army had already been bombarded by mortars, and there were basically few people left, and two street forts were also destroyed. Now in the face of the assault of heavy armored vehicles and a company of infantry, the line of defense was broken through without much resistance. While the armored vehicles continued to assault the second line of defense of the Japanese army, the Japanese mountain artillery launched another artillery bombardment. Tang Weiren, who had been waiting for a long time, immediately calculated the coordinates of the Japanese mountain artillery position, and when the Japanese mountain artillery fired the third round of shells, Tang Weiren and the others had already calculated the direction of the Japanese mountain artillery position.

Then the twenty-four field guns of the field artillery battalion roared at the same time, and the vengeful shells screamed and rushed towards the Japanese mountain artillery position, and in an instant the shells exploded in the distance with puffs of black smoke, and with the sound of explosions, the Japanese artillery fire stopped. One of the two heavy armored vehicles of the assault was blown up by the Japanese, and one was very lucky, several shells exploded around it, but none of them fell directly on it.

The infantry of a company of the assault was not very good, with only more than 30 casualties. After the Japanese artillery fire disappeared, the soldiers of this intact armored vehicle and assault company did not retreat, but continued to break through to the second line of defense of the Japanese army. When Li Jieli found out about this, he immediately sent two other companies of the first battalion to reinforce him, and Jin Zige also sent one heavy armored vehicle and two light armored vehicles at the same time.

With the reinforcements in the back, the soldiers who attacked first were more confident, and the Japanese army still built two street forts on the second line of defense, and the two heavy machine guns in the street forts kept spitting tongues of fire. The heavy armored vehicles that rushed ahead were also splashed with bullets from the heavy machine guns in the street forts. The commander of the car ordered a stop in a fit of rage, and then directed the guns on the car to aim at the firing hole of the street fort, which was a series of shots.
