Commander Imamura shuddered at the thought that once the Lang Son line was lost, the Chinese army would tend to attack Hanoi, and that there would be no more danger from Lang Son to Hanoi. Commander Jun Imamura immediately summoned Major General Masao Takahashi, the commander of the 30th Brigade, who was independently mixed into the 30th Brigade, and asked Major General Masao Takahashi to lead his brigade to the Langsan defense line immediately tomorrow. Major General Masao Takahashi also shirked and responded: "Yes, Your Excellency the division commander, your subordinates will leave immediately tomorrow morning!"

Early the next morning, after seeing off the 30th Independent Mixed Brigade led by Major General Takahashi Masao, Commander Jun Imamura immediately sent a telegram to Major General Yukio Akita, telling Major General Yukio Akita that he had sent the 30th Independent Mixed Brigade to Lang Son for reinforcements, and asked Major General Yukio Akita to hold the Lang Son defensive line. After sending the telegram, Commander Imamura was a little relieved.

Just as Major General Takahashi Masao led his troops to leave Hanoi, the two regiments of the 277th Brigade also began their attack on the heights of Ba Wai Mountain. As yesterday, the two battalions of the Heavy Artillery Regiment first used artillery fire to attack the Japanese positions on the heights of the Bawai Mountains for half an hour. However, the two battalions shelled today were the 150 heavy howitzer and artillery battalion and the 122 howitzer and artillery battalion, which were in a more suitable position.

Although the number of artillery pieces of the two battalions was not as large as yesterday, it was more powerful than yesterday. The sound of explosions on the high ground of Bawai Mountain continued one after another, and the smoke of gunpowder filled the air, and the flames were everywhere. Today's main attack is the 569th Regiment. With yesterday's precedent of the 568th Regiment taking the Kumashan Heights in one day, Wei Yongshou, commander of the 569th Regiment, was not to be outdone, and sent both the 1st and 2nd Battalions in the first attack.

Before the attack, regiment commander Liu Yongshou explained to Deng Fei, commander of the first battalion, and Liu Jun, commander of the second battalion, that he wanted the first and second battalions to take the position on the mountainside of the Japanese army in one attack. There are similarities and differences between Bawai Mountain and Kuoma Mountain, the similarity is that the height is about the same, the slope is also similar, the difference is that the vegetation on Bawai Mountain is more sparse, and some huge rocks have become natural obstacles when attacking.

The Japanese defenders placed on the hill outside Bawai were also an infantry brigade, while the first line was garrisoned by two infantry squadrons on the position halfway up the mountain. Another difference between this Bawai Mountain and Kuoma Mountain is that there are many large or small natural caves on Bawai Mountain, and these caves naturally became places for the Japanese army to hide from shelling. However, the casualties were not large, but the fortifications on the position were destroyed under the repeated bombardment of artillery fire.

After half an hour of shelling, the 1st and 2nd Battalions simultaneously launched an attack on Bawaishan, and Wei Yongshou led the 3rd Battalion and the Heavy Firepower Battalion to cover the 1st and 2nd Battalions with heavy machine guns and mortars. This time, the Japanese had few machine gun fires that were hiding in the bunkers, but a few light and heavy machine guns were mounted on the edge of the trench, and they were firing frantically from a high position.

This situation was difficult for the attacking soldiers, Deng Fei selected dozens of magic machine fighters in the battalion to specifically aim at the Japanese machine gunners, and all the machine guns in the battalion were also used to suppress the Japanese soldiers who were shooting on the position. Under such a blow, the machine guns on the Japanese position were dumbfounded, and the soldiers did not dare to raise their heads, but the only thing that threatened them was the grenades and bullets fired from the grenadiers hiding behind the trenches.

The number of grenades and bullets fired was not small, and many fighters fell on the way to attack because of it. Wei Yongshou noticed this situation and commanded the artillery to attack the places where grenades and shells were flying, and under the blows of the mortars, the grenades and shells flying in became fewer and fewer, and the firepower on the position was also weakened. The officers and men of the 1st and 2nd Battalions seized the opportunity to launch a charge, and by the time they were only 30 or 40 meters away from the Japanese position, the firepower on the Japanese position was already very weak.

The fighters threw another round of grenades and bullets at the position, and rushed to the position in the smoke of gunpowder. When the soldiers rushed to the ground with their bayonet rifles and broadswords, the expected hand-to-hand combat did not take place, and they only saw the backs of the Japanese soldiers fleeing towards the hill and the corpses of the Japanese soldiers lying on the ground. At this time, there were more than a dozen seriously wounded people who tried to die with the soldiers who rushed up, but they were basically killed on the spot.

After cleaning up the battlefield, some soldiers reported the results to Deng Fei, killing 158 Japanese soldiers on the battlefield, and the 1st and 2nd battalions combined suffered 46 casualties. After Deng Fei sent people to escort the wounded soldiers down, he prepared to continue the attack on the mountain. This time, Liu Jun, the commander of the second battalion, rushed to the front, and he led the officers and men of the second battalion to rush out of the position first.

The Japanese troops in Bawaishan did not seem to have the determination to hold their positions to the death, and they held on for a period of time, but once the offensive of the 569th Regiment became fierce, or their own troops suffered heavy casualties, they would retreat, and the 568th Regiment did not even use the three battalions, and only relied on the assistance of the first and second battalions plus heavy artillery, and easily connected the second line of positions and the hilltop position.

An infantry brigade of the Japanese army was only wiped out by the 589th Regiment of more than 300 people, and nearly 1,000 Japanese soldiers fled from the heights of Bawai Mountain. At noon, the 589th Regiment occupied the heights of Bawai Mountain. It was so easy to take the high ground of Bawai Mountain, so that Mu Suzhong felt like he had hit the cotton pile with a punch with all his strength. It's not a comfortable feeling.

After the news was reported to Li Yuanhong, even Li Yuanhong could not believe it, and in order to prevent the Japanese army from playing tricks, Li Yuanhong immediately reported the situation to Wang Haitao, and suggested that Wang Haitao send a reconnaissance team to find out the movements of the Japanese army before continuing to attack. When Wang Haitao received Li Yuanhong's telegram, he also had some doubts in his heart, and immediately ordered Tang Xiaoshan to reconnoiter the movements of the Japanese army and order the 93rd Division to rest and stand by.

A day later, Tang Xiaoshan sent a telegram back to Wang Haitao, saying that he had found out that the Japanese army had now retreated to the two towns of Lang Son and Dong Dang due to insufficient troops. In addition, the reconnaissance unit also discovered that the Japanese reinforcements had set out from Hanoi and rushed to Lang Son City, which was numbered as an independent mixed 30th Brigade with about 8,000 troops, and it was expected to arrive in Lang Son City within two days at the earliest.

After reading the telegram sent by Tang Xiaoshan, Wang Haitao knew that the attack on Lang Son should be hurried, otherwise the arrival of Japanese reinforcements would increase the difficulty of attacking Lang Son City. Wang Haitao also regretted that he had lost a day in vain. With Tang Xiaoshan's telegram, Wang Haitao immediately sent a telegram to Li Yuanhong, asking the 93rd Division to set off immediately and attack Langshan City. He also told Li Yuanhong that an independent mixed brigade of the Japanese army was reinforcing Lang Son City, which was expected to arrive in Lang Son City in two days.

The whole division of the 93rd Division had already prepared to set off, just waiting for Wang Haitao's order to attack, and now as soon as Wang Haitao's order arrived, Li Yuanhong immediately asked the troops to set off, and the 277th Brigade still opened the way in front. The 277th Brigade spent three hours on the dilapidated road and traveled five kilometers. As soon as I crossed the mountain road at the foot of Bawai Mountain, I saw a town appear in the distance.

Mu Suzhong thought that he had arrived in Lang Son City, so he opened the map and carefully compared the terrain type, only to know that this was only a county seat not far north of Lang Son City, Wendeng County. After sending out the reconnaissance troops, the 277th Brigade led with the 568th Regiment, and the whole brigade came to a stop two kilometers away from the county seat, because the reconnaissance unit reported that a large number of Japanese troops had been found in the county seat of Wendeng.

On the one hand, Mu Suzhong asked the troops to prepare for the siege of the city, and on the other hand, he reported to Li Yuanhong and asked to send the division's heavy artillery regiment to help in the battle. Le Yuanhong was also anxious to capture Lang Son City, but the heavy artillery of the heavy artillery regiment was too slow on this dilapidated road in Vietnam, and it was estimated that it would be the afternoon when the heavy artillery regiment crossed the mountain road and joined the 277th Brigade. Fortunately, the light armored vehicles of the armored brigade were okay to take this road, and Wu Jianzhou had already sent a battalion of light armored vehicles to quickly join up with the 277th Brigade to assist the 277th Brigade in attacking.

Knowing that the division's heavy artillery regiment could not catch up for the time being, Mu Suzhong could only concentrate dozens of 100-caliber heavy mortars to serve as attack cover, and the first to attack was the 570th Regiment. When regiment commander Liu Yuzhu received the brigade commander's order for their regiment to attack first, he became excited and issued orders to his subordinates one after another.

First of all, all the heavy machine guns in the regiment formed a heavy machine gun position, selected a suitable position, and made every effort to suppress the Japanese troops on the city wall, and then the small-caliber artillery guns in the regiment were used to approach and attack the Japanese fire points on the city wall. The last three battalions spread out and attacked the walls in a skirmish formation. As soon as Liu Yuzhu was arranged, the bombardment of the heavy artillery began.

With the sound of cannons, the northern wall of Wendeng City was shrouded in gunsmoke, and there were continuous fires in the smoke. After five minutes of shelling, Liu Yuzhu ordered the whole regiment to attack, so under the cover of dozens of heavy machine guns, three battalions launched an attack on Wendeng City at the same time. As soon as the attack began, shells flew out of the city, half of which landed on the heavy mortar positions and half on the heads of the attacking soldiers of the 570th Regiment.

The 277th Brigade suffered a loss due to the sudden counterattack artillery fire of the Japanese army, and not only more than 20 heavy bombardment guns were blown up, but the soldiers of the 570th Regiment were also blown down in pieces. The key point was that as soon as the bombardment of the heavy artillery weakened, a large number of Japanese troops appeared on the city wall, and all kinds of firepower began to block the soldiers of the 570th Regiment attacking.

Liu Yuzhu immediately ordered the small-caliber mortars in the regiment to strike at the machine-gun fire points on the city wall, and let the heavy machine guns strengthen the suppression of the Japanese troops on the city wall. However, the Japanese artillery fire was always firing shells outside the city, which also made the casualties of the 570th Regiment more and more large, Liu Yuzhu saw that not only could not capture the city wall if this continued, but also the casualties in the regiment were too large, so he ordered the troops to withdraw first.

The defeat of the offensive poured cold water on the 277th Brigade, and also made Mu Suzhong pay attention to the Japanese army again. Chen Kong, commander of the 568th Regiment Fire Battalion, who was in charge of commanding the heavy artillery artillery, reported to Mu Suzhong: "Brigade seat, according to my observation, there are at least 10 Japanese mountain artillery pieces in the city, and it should be a mountain artillery brigade of the army. This time, we lost 26 100-caliber heavy mortars at once, and I am afraid that we will not be able to start an artillery battle with the Japanese army. ”
