In the daytime battle, the losses of the 277th Brigade were not too large, but more than 200 people were killed and more wounded. Fortunately, a group of medical personnel were replenished before departure, and now the medical staff in the temporary ambulance station are quite sufficient, and the wounded are sitting or lying, and the wounds have basically been treated. After years of fighting, the medical staff are also experienced, and the operation in the operating room is still going on, but with penicillin, the number of wounded deaths due to wound infection has been greatly reduced.

In the temporary infirmary, Li Yuanhong comforted the wounded while patrolling, and when he heard that there was a scolding mother, he didn't mind, but stepped forward to explain patiently. Li Yuanhong inspected the temporary medical center for an hour and did not return to the division headquarters until it was almost dark. At this time, Huang Gang also sent someone to report that the troops had reached the outskirts of Lang Son City, and established a position, waiting for the next order of the division.

Li Yuanhong sat in the command headquarters and thought for a while, and called Brigade Commander Mu Suzhong. As soon as Mu Suzhong entered Li Yuanhong's office, Li Yuanhong greeted him. After letting Mu Suzhong sit down, after briefly asking about the situation of the troops, Li Yuanhong said to Mu Suzhong: "Old Mu, the military seat has sent a telegram saying that more than 8,000 people of the 30th Independent Mixed Brigade of the Japanese army reinforcing Langshan City will arrive in Langshan City tonight. We're still a step too late. ”

After hearing this, Mu Suzhong replied: "Division, there are quite a lot of Japanese troops in Langshan City now, can only one brigade of the 278th Brigade attack it?" Li Yuanhong replied: "I am also worried that the 278th Brigade will not have enough troops. I want your brigade to send two regiments up to attack Lang Son City with the 278th Brigade, what do you think?" Mu Suzhong was already preparing to ask for battle, but Li Yuanhong's words were right in the heart.

Mu Suzhong stood up, stood up and said, "Don't worry, I will go to assemble the team immediately and personally lead the team to join the 278th Brigade." Li Yuanhong smiled and sat down, and then said: "Don't worry, now the attack on Langshan City is required to be stable." The telegram also said that he would send an armored brigade and a heavy artillery brigade to assist our division in attacking Lang Son City, and you should go back first to prepare the troops for battle, and then act together when the armored brigade and heavy artillery brigade are together. ”

Mu Suzhong said: "Yes, division! I will go back to the troops to prepare first, and as soon as the armored brigade and heavy artillery brigade arrive, I will immediately move with the two brigades." Seeing Li Yuanhong nodding, Mu Suzhong said goodbye and left. Back at the brigade headquarters, Mu Suzhong called all three of his regiment commanders over, and then said: "The Japanese reinforcements have arrived in Lang Son City, and the division is worried that the 278th Brigade will not have enough troops to attack Lang Son City, so he ordered our brigade to send two regiments to participate in the battle, which two regiments do you think is appropriate to send?"

The three regiment commanders all wanted to go, the three of them looked at each other, or Li Chunshan said with a wry smile: "Our 568th Regiment has fought several times in a row, and the losses are not small, and now among the three regiments, I am afraid that our regiment is the weakest, this time our regiment will stay in Wendeng!" Seeing that Li Chunshan stood up and expressed his position, Li Yuanhong glanced at Wei Yongshou and Liu Yuzhu and asked, "What do you two say?"

Wei Yongshou replied: "The 568th Regiment gave the opportunity to our two regiments, and we will definitely not let the brigade down." Li Yuanhong nodded and said, "Okay, you guys make all the preparations after you go back, and when the armored brigade and heavy artillery brigade arrive, you will act with them immediately." Wei Yongshou and Liu Yuzhu returned to the station excitedly, and immediately ordered their subordinates to replenish ammunition and materials, check firearms, and make all preparations for battle.

At ten o'clock in the evening, dozens of combat vehicles of the armored brigade rushed outside the city of Wenden. Brigade commander Wu Jianzhou ordered the troops to set up a camp outside the city for rest, and went into the city himself to point to Division Commander Li Yuanhong. This time, the armored brigade did not all sorts out, there was only one battalion of 18 Type 62 light tanks, one battalion of heavy armored vehicles and 18 heavy armored vehicles, and the rest was the light armored vehicle regiment, and the light armored vehicle battalion that came before had already gone to the Lang Son front, and now there are only two battalions and 36 light armored vehicles.

Li Yuanhong got to the point after seeing Wu Jianzhou, because Wang Haitao had an order to let the armored brigade fully cooperate with the attack of the 93rd Division, and Li Yuanhong's military command was higher than Wu Jianzhou, so Wu Jianzhou's posture was very low. Wu Jianzhou said to Li Yuanhong: "Division Commander Li, if you have any requirements for our armored brigade, just say it, we will definitely fully cooperate." ”

Li Yuanhong didn't dare to hold it up, and said: "Brigade Commander Wu is polite, this attack on Langshan City, because the Japanese reinforcements have arrived, I am afraid that it will be a little difficult to attack, I hope that the armored brigade of Brigade Commander Wu and the armored regiment of our division will work together to cover the attack of the infantry." In peacetime, our division has also practiced infantry and tan cooperative operations many times, and this time I hope to give full play to what we have trained in peacetime in actual combat. This is inseparable from the active cooperation of your armored brigade!"

Wu Jianzhou smiled and said: "Although Commander Li can rest assured, with the cooperation of our armored brigade and the support of the heavy artillery brigade, we will definitely be able to successfully capture Langshan City." The two chatted for a while, and Wu Jianzhou took his leave to prepare. The two regiments of the heavy artillery brigade did not arrive outside Wendeng until midnight, and Tang Yishi, the commander of the heavy artillery brigade, rushed to see Li Yuanhong overnight.

The distance from Wendeng County to Lang Son City is less than 10 kilometers, and the heavy artillery of the Heavy Artillery Brigade can completely cover Lang Son City from Wendeng, so the Heavy Artillery Brigade is ready to choose a suitable position here in Wendeng County to establish an artillery position. Li Yuanhong would not object to this, and he also transferred two battalions from the divisional guard regiment to take up the task of guarding and protecting the heavy artillery brigade.

Early the next morning, Huang Gang stood on a high place and observed the Japanese position opposite with a telescope. The width of the Japanese position was more than 100 meters, and behind the position was the Qianqi River, and the only iron bridge over the river was also behind the Japanese position. Pillboxes, bunkers, sandbag bunkers, and trenches were distributed layer upon layer on the position, and there were horse rejections and barbed wire in front of the position.

According to the report of the reconnaissance group, the Japanese army increased its strength in the middle of the night, and now the number of Japanese troops stationed on the position should exceed 1,000. After observing for a long time, Huang Gang decided not to wait any longer, he wanted to send a battalion up first, and launch a feint attack under the cover of the armored regiment, so as to find out the distribution of the Japanese army's fire points and prepare for the later attack. Huang Gang sent a telegram requesting an attack directly to Li Yuanhong.

Just as Huanggang sent a telegram to Li Yuanhong, Major General Yukio Akita was also observing the Chinese troops opposite from a pillbox on the Japanese position. In the evening, the 30th Independent Mixed Brigade arrived in Lang Son City, which made Major General Akita Yukio reassured. Originally, there was only one infantry brigade, a mountain artillery squadron, and a chariot brigade in Lang Son City, and it was very difficult to hold Lang Son City, and then several hundred people escaped from Wendeng.

Now that the reinforcements arrived, Lang Son City had nearly 10,000 defenders, and Major General Akita Yukio thought that holding Lang Son City should not be a big problem. After meeting with Major General Masao Takahashi, the commander of the 30th Independent Mixed Brigade, Major General Yukio Akita handed over the defense of the city south of the Poor Chi River, that is, the city of Lang Son, to the Independent Mixed 30th Brigade, while all his own troops reinforced the positions north of the river. Now all the remaining troops of the Akita detachment, more than 2,500 people, have arrived at the Hebei position.

The request for the attack on Huanggang was approved by Li Yuanhong, and the division's heavy artillery regiment and armored regiment were ordered to cooperate with the attack of the 278th Brigade. Tang Weiren had an extra eye this time, anyway, the 278th Brigade only made a feint attack at the beginning, so Tang Weiren only ordered the 75th Field Artillery Battalion to shell the Japanese position, and the target was mainly the obstacles in front of the Japanese position and the soldiers in the trenches in front.

Huanggang handed over the task of the first attack to the 1st Battalion of the 571st Regiment, which was accompanied by two Cheetah tanks, four light tanks, four heavy armored vehicles, and eight light armored vehicles of the armored regiment. After the troops were in position, Huanggang fired 24 75-caliber field guns first, and the shells fell on the obstacles in front of the Japanese position, and the horses and barbed wire were torn apart in the explosion, and some flew directly into the air.

Major General Yukio Akita, who was observing the situation, was startled by the shelling by the Chinese army, and after seeing the location and effect of the shells, he gave a little refreshment, the Chinese army used to shell 75-caliber artillery, which was not powerful enough to destroy the fortifications on the position. But after a while, after the artillery fire was extended, through the smoke of gunfire, Major General Akita Yukio saw more than a dozen large and small chariots coming out of the Chinese army, and hundreds of Chinese soldiers were advancing with these chariots.

At this time, Major General Yukio Akita became nervous again, and immediately ordered the squadron of rapid-fire guns in the front position to prepare to deal with the rushing chariots. This rapid-fire gun squadron of the Akita detachment is equipped with twelve rapid-fire guns of 37 mm caliber, which can shoot through the armor of light tanks when used*, not to mention armored vehicles, but it cannot deal with Cheetah tanks.

The officers and men of the 1st Battalion of the 571st Regiment, under the leadership of the battalion commander Xiao Shuyun, followed the chariot to a point only 200 meters away from the front of the Japanese position, when the Japanese opened fire. Dozens of light and heavy machine guns were fired from pillboxes, bunkers, sandbag fortifications, and trenches, and bullets rained down. Not to be outdone, the charging tanks and armored vehicles returned fire with vehicle-mounted artillery and vehicle-mounted heavy machine guns.

On the offensive position, Huang Gang saw that all the Japanese machine gun fire points were firing, and ordered the concentrated heavy mortar group to aim at the Japanese fire points. Dozens of heavy mortars were not good against pillboxes and fortifications, but sandbag fortifications and machine-gun fire points in the trenches could not withstand its bombardment. The Japanese positions bombed by numerous artillery pieces were filled with gunsmoke and flames, and from time to time Japanese soldiers and guns were blown into the air and fell in pieces.
