Under the deterrence of anti-aircraft guns, Japanese planes did not appear in the sky of Lang Son City for two days in a row, and during these two days, Li Yuanhong's 93rd Division had a good rest, and cooperated with the engineering troops to repair the damaged iron bridge, which could be repaired again for Cheetah heavy tanks. The ensuing assault on Lang Son Castle was about to begin again after five days of stagnation.

In the past two days, the planes have stopped coming to support, and Major General Takahashi Masao in Langsan Castle knows that it is not good, but Major General Takahashi Masao has personally witnessed the process of a field air battle, and he is naturally clear about the losses of the flight troops. Seeing the losses of the flying unit again and again, Major General Masao Takahashi was also saddened and helpless.

The fact that the Chinese army did not attack the city in the past few days also gave Major General Takahashi Masao and his brigade more time to prepare. The strength of the 30th Brigade of the Independent Mixed Brigade is not bad, there are not only five infantry brigades, but also a mountain artillery brigade and an independent mortar squadron. Knowing that the Chinese army had a large number of large-caliber heavy artillery, Major General Takahashi Masao understood that the walls of Lang Son Fortress could not stop the bombardment of heavy artillery.

Therefore, Major General Takahashi Masao placed only one infantry squadron on the northern wall, and the vast majority of the brigade was in the city. In the past few days, the 30th Brigade has been independently mixed into the city of Lang Son and has made use of all available terrain to arrange countless street forts and fortifications, and anyone who knows how to do it can understand at a glance that the Japanese army is preparing for street fighting.

Indeed, Major General Masao Takahashi was indeed preparing to fight an urban offensive and defensive battle with the attacking Chinese army. Since the Japanese war of aggression against China in 1937, almost all of the Chinese army has used street fighting to deal with the Japanese army in defense, and now the Japanese army actually wants to use street fighting to deal with the attacking Chinese army, which seems to be a joke, but Major General Takahashi Masao put himself on the weak side.

Indeed, in the face of the heavy artillery and tanks of the Chinese army, the 30th Brigade of the Independent Mixed Brigade had no ability to resist hard, and Major General Takahashi Masao could only accept with a wry smile the fact that his troops had become weak. After preparing to launch another attack on Lang Son City, Li Yuanhong asked Wang Haitao for support from the heavy artillery brigade because the heavy artillery losses of the division's heavy artillery regiment were too large, and Wang Haitao readily agreed.

At eight o'clock in the morning of the siege, on the position of the heavy artillery brigade outside the city of Wendeng, with a series of orders: "Open the cannon!" 50 heavy guns of the 130-caliber heavy cannon regiment and 50 heavy guns of the 152-caliber heavy howitzer and artillery regiment opened fire at the same time, and the powerful shells flew towards Lang Son City several kilometers away. According to the azimuth coordinates provided by observers, the shells landed accurately on the walls of Lang Son Castle.

This time the artillery fire was more intense than the first bombardment, not only the shells were denser, but also more powerful. Major General Masao Takahashi looked at the bombed north gate wall at the gate of the command post, even if he had been mentally prepared, his face still changed drastically. What he didn't expect was that the Chinese army had not yet shown its full strength in the first bombardment of the city wall, and now it seemed that the Chinese army he was about to face was stronger and more terrifying than he imagined.

After only ten minutes, the wall of the north gate of Lang Son City partially collapsed, and then the gap became more and more and larger. Twenty minutes later, the heavy artillery bombardment finally stopped, and the smoke cleared slightly, revealing the battered North Gate wall in the eyes of Major General Takahashi Masao. Five or six of the walls collapsed, three of which were more than 20 meters wide.

Even if it was a street fight, it would not be easy for the Chinese army to enter the city, and Major General Takahashi Masao shouted to instruct his men to send additional men to several gaps. The 1st Infantry Brigade was still in charge of guarding the north gate wall, and the captain of the group, Yokono Kawafu Osa, was also a very experienced officer, and immediately after the heavy artillery stopped bombardment, he immediately added troops to several gaps.

Outside the city, as last time, the 569 and 5702 regiments had crossed the Qianqi River from the iron bridge and were ready to attack. Accompanying the officers and men of the two regiments across the river were forty armored brigades of various combat vehicles. As soon as the heavy artillery bombardment stopped, the forty chariots parked a thousand meters away from the city wall increased their horsepower and rumbled towards the city wall, and behind them were the officers and men of the 569th Regiment.

There were still four Cheetah heavy tanks in front of the tank, followed by ten light tanks. The fourteen tanks formed a triangular attack formation and quickly drove towards the city walls. When it was less than 400 meters away from the city wall, the machine gun fire point guarding the city wall that had not collapsed couldn't help but fire first, and the heavy machine gun bullets clanged into the tank body.

These bullets did not cause the slightest damage to the charging tank, but instead caused the tank to counterattack because of the exposed position. The tank guns on the tanks aimed at these machine-gun fire points one after another, and fired back as they advanced. More than a dozen tank guns completely destroyed several machine gun fire points in only two rounds, and the heavy machine guns on the board also caused heavy casualties to the Japanese troops on the city wall.

As they were about to reach the bottom of the city walls, the tank stopped, and after flashing a few passages, concentrated its machine-gun fire on the three wide gaps. Behind them, twelve light armored vehicles, with the cooperation of the 569th Regiment, crossed the tanks and rushed straight into three gaps. In each of these three gaps, Yokono Kawafu Osa arranged the strength of an infantry squadron, and the Japanese saw that the Chinese tanks and infantry were attacking together, and they fought back desperately against the strafing of the heavy machine guns on the vehicles.

However, in a gap of 20 meters wide, there were no less than 20 heavy machine guns suppressive strafing, and the Japanese army could not resist even if they were desperate. Seeing the continuous death of his soldiers, the corpses of the dead soldiers at the gap were covered with a thick layer, and Yokono Kawafu Osa couldn't help but feel a chill in his heart. After only holding out for about ten minutes, one of his infantry brigades suffered more than half of the casualties, and Yokono Kawafu Osa had no choice but to order all of them to retreat.

The 569th Regiment, closely followed by 12 light armored vehicles, broke through the Japanese resistance at the gap at a very small cost, and rushed into Lang Son City with light armored vehicles. The 570th Regiment that followed behind saw that the 569th Regiment had broken into the city, and hurriedly quickened its pace and rushed towards the gap. As soon as the 569th Regiment rushed through the city wall, before it could be deployed, a burst of bullets was fired at the front, and the soldiers hurriedly scattered and hidden.

After finding cover, the regiment commander Wei Yongshou looked at it and couldn't help but scold: "The little Japan raised by the son of a bitch, this is to play street fighting with Lao Tzu!" It turned out that in the center of the street, which was only fifty meters away, the Japanese army built two bunkers, and the heavy machine guns in the bunkers kept spitting flames, and the armored vehicles in front also stopped.

The troops that rushed into the city did not suffer much loss because they had light armored vehicles in front of them, but there were too many soldiers who rushed into the city, and in such a narrow street, they could not be dispersed at all, and they could not form much combat effectiveness. Wei Yongshou immediately made a decision and ordered the second and third battalions to withdraw from the city first, leaving space for the first battalion to open up the situation.

The 2nd and 3rd Battalions were ordered to retreat, but the 570th Regiment behind them came up, and for a time there was confusion in the three gaps, but the Japanese seized the opportunity to shoot several rounds of shells at the gaps with several mortars in disguise. The soldiers who were blocked in the gap were blown down a few pieces at once, and the two regiment commanders, Wei Yongshou and Liu Yuzhu, who were in a hurry, shouted in succession: "Quickly withdraw out, quickly!"

Li Yuanhong, Huang Gang, and Wu Jianzhou, who were watching the battle with binoculars in the distance, had seen the armored vehicles and infantry rushing into the city, and they had just breathed a sigh of relief, when suddenly gunshots and explosions rang out in the city.

Li Yuanhong and the others were also a little puzzled, they didn't know what was going on in the city, but suddenly there was a cannon sound in the city, and then the cannonballs exploded in the gap, and a lot of soldiers fell in a pool of blood. Seeing that Li Yuanhong's face had changed drastically, Huang Gang also hurriedly said: "What's going on? How did Wei Yongshou, the regiment commander, command? Nonsense!" Fortunately, the width of the gap was not large, and after a few rounds of artillery fire from the Japanese army, the soldiers in the gap took refuge one after another.

There were more than 100 casualties here, which made Wei Yongshou and Liu Yuzhu regret it. Wei Yongshou and the first battalion were still in the city, Wei Yongshou found the first battalion commander Deng Fei, and said to Deng Fei: "Battalion commander Deng, the Japanese army has been prepared for a long time, this is to fight with us in the street, now you first send people under the cover of armored vehicles to blow up the two bunkers at the entrance of the alley, and then occupy the street entrance first." ”

Deng Fei looked at the two bunkers and replied, "Yes, Tuanza! The eight intact armored vehicles in the city were also in danger at this time. After the infantry found cover and hidden, these eight armored vehicles became the main target of the Japanese attack. Eight armored vehicles were constantly moving, dodging grenades, shells, and throws* from the Japanese army, while returning fire with vehicle-mounted heavy machine guns.

Just after the first battalion was ready for the attack on the bunker, only five armored vehicles were intact, and three more were shot and lost their ability to move. However, the Japanese army also paid the price of hundreds of people under the heavy machine gun attack of armored vehicles. The demolition team attacking the bunker, under the cover of light and heavy machine guns behind them, moved towards the two bunkers, and the armored vehicles that were still wandering discovered the actions of the demolition team, and after understanding their intentions, they also took the initiative to take on the task of covering.

The two armored vehicles, without hesitation, increased the throttle and rushed towards the street bunker, blocking the firing holes of the bunker with machine guns as they charged. The other three armored vehicles stopped and fired machine guns at the Japanese soldiers who were shooting from the houses on both sides of the street. The five armored vehicles managed to attract the attention of the Japanese army, so that the Japanese did not notice the existence of the explosive group. After approaching the two bunkers, the demolition team placed the explosives and powder packs, pulled them and quickly evacuated, and with two loud noises, the two bunkers blocking the advance of the fighters were blown into the sky.
