The Japanese air raids continued, and two bombers dropped aerial bombs back and forth on the regimental headquarters of the Independent Regiment in Binh Dinh County.

The four bombers carried out carpet bombing on Naozhai Mountain, and one aerial bomb after another exploded in Naozhai Mountain.

At 4:20 a.m., the Japanese bombers finished their bombing, and the Japanese pilots circled the air triumphantly and then left.

They learned the lessons of the previous and did not dare to strafe at low altitudes.

The air was filled with the smell of gunsmoke, and the scorching waves of air did not completely dissipate, and the smell of charred corpses gradually came.

The position on the top of the mountain was completely destroyed, the soil was hot, and there was a lot of shrapnel in it.

The two 20mm machine guns of Liu Xi's second company were completely destroyed, and the shooters of these two machine guns launched heroic fire when the Japanese bombers came.

BUT BECAUSE THE BOMBER MAINTAINED A CERTAIN ALTITUDE, THE 20MM CANNON COULD NOT POSE A THREAT TO THE BOMBER AT ALL.

On the contrary, the machine gun opened fire and revealed its position, and was directly destroyed by the aerial bombs dropped by the Japanese bombers.

The artillery battalion and Liu Xi's infantry company paid a lot of price, especially the artillery battalion, the battalion commander Shi was killed, the commander of the second artillery company, Zheng Jingjing, was wounded, and four of the six 94-type mountain guns of the second artillery company were destroyed, and only two can continue to be used at present.

The artillerymen also paid for the wounding of dozens of people, and the artillery position, which was originally full of bullet shells, already had a lot of corpses at this time.

Liu Xi dispatched Wang Tieniu's sixth platoon to quickly reinforce him, and he asked Wang Tieniu's sixth platoon to assist the artillery in sorting out the position.

After some fighting, Wang Tieniu's sixth platoon had already paid the casualties of one infantry squad, and only two squads were able to continue fighting.

The infantry of these two squads, led by Wang Tieniu, immediately came to the artillery position, and they buried the bodies of the dead artillerymen with sad faces.

However, most of the artillerymen did not leave a single intact corpse, and severed arms and limbs were everywhere in the artillery positions.

The Japanese air raid brought great losses to the Naozhai Mountain position, but the independent regiment had neither professional air defense weapons nor aircraft to help the battle, so they could only bear it silently, and they had nothing else to do.

Liu Xi quickly got in touch with the regimental headquarters of the Independent Regiment, and he reported the situation on the position in Naozhai Mountain.

It was Zhao Lerong, chief of staff of the regiment, who spoke with Liu Xi, and after learning of the loss of the position in Naozhai Mountain, Zhao Lerong immediately asked Sun Weiguo for advice.

Sun Weiguo immediately issued an order, and he asked Li Jiaxin, the company commander of the first artillery company, to temporarily take over the command, and the troops continued to stick to the position on Naozhai Mountain, waiting for the order of the regimental headquarters.

The Japanese air raid ended, the Naozhai Mountain position returned to silence, and the Japanese detour troops of an artillery wing, an infantry brigade, and a tank squadron, they continued to march towards the south side of Naozhai Mountain, they still wanted to suppress the artillery units of the Naozhai Mountain Independent Regiment, and cooperate with the attack of the two infantry wings.

Because the roundabout troops were marching, they naturally did not continue to attack the position of Naozhai Mountain.

However, here at the regimental headquarters of the Independent Regiment, the First Infantry Wing and the Second Infantry Wing of the Devil's Garrison Corps began to launch a fierce attack on the position of the regimental headquarters of the Independent Regiment.

The Japanese army was the main force of the 2nd Infantry Wing departing from Nanzhuang Village, and the Japanese troops seemed to be intending to break through the positions of the regimental headquarters of the Independent Regiment in one go.

The 2nd Infantry Wing, which threw two infantry brigades, three tanks, five armored vehicles, six infantry guns, launched an attack from the frontal of the regimental positions.

The 1st Infantry Wing threw in an infantry brigade with three infantry guns, and they attacked on the flank of the independent regiment.

The Japanese concentrated more than 3,000 men to storm the regimental headquarters of the independent regiment, but only two companies were responsible for guarding the positions of the regimental headquarters.

Even though the fortifications here at the regimental headquarters were very strong, in the face of a large number of Japanese troops, the pressure of the defenders could be imagined.

However, fortunately, the artillery of Naozhai Mountain was quickly put into battle, and Li Jiaxin commanded several mountain guns to continuously fire shells, which brought great support to the defenders.

Inside the regiment headquarters, Tang Chunhua, a staff officer of the Second War Zone, looked outside through the observation hole, looking at the group of Japanese soldiers with steel helmets, Tang Chunhua's face became pale, he turned back to Sun Weiguo, and his expression was speechless and stopped.

Tang Chunhua had the idea of simply finding a chance to run out, and surrendering if he really couldn't do it, but he didn't dare to say this idea.

Zhong Jian and Shen Wei frowned tightly, they looked at the many Japanese troops, and the two of them were inevitably full of worry.

Sun Weiguo sat on the chair with a calm expression, his eyes looked at the map, and he was carefully calculating in his heart.

Zhao Lerong held a telescope to observe the situation of the position, and the expression on his face was not very nervous.

From time to time, bullets from the light and heavy machine guns of the little devils would hit the wall outside the regimental headquarters, and occasionally one or two grenades would explode outside.

The most dangerous was when a rifle bullet hit the observation hole and pierced the ear of a communications soldier.

Seeing that Tang Chunhua was so frightened that he was about to sit on the ground, Sun Weiguo asked Chen Zhengwei, the leader of the guard squad, to immediately send Tang Chunhua and the two reporters to the underground bunker.

"Weiguo, are we still sure of breaking through?" Zhong Jian came to Sun Weiguo, and he said with a solemn expression.

"Commander, you don't have to worry, we still have a breakthrough, but we are indeed facing a lot of pressure here. Whether they can hold out to the end depends on whether the two companies of Liu Jingnuma and Chen Yang can hold their positions. Sun Wei said calmly in Chinese.

He glanced out through the observation hole, a slight solemn expression in the depths of his eyes.

Sun Weiguo was worried about the situation here in the cavalry battalion, and he was even more worried that the Japanese commander was not in Pingding County.

It's just that Sun Weiguo's worries are a little superfluous, even if Yamashita Fengwen treats Sun Weiguo as a big trouble.

However, having a dignified Japanese lieutenant general and corps commander personally go to the front line to command more than 10,000 troops to encircle and annihilate the Eighth Route Army, which was more than 1,000 people, was unwilling to do such a humiliating thing, so Yamashita Fengwen set up the corps headquarters in Pingding County, where he commanded the troops to fight.

At this time, outside the county seat of Pingding, the four companies of the cavalry battalion had quickly completed the assembly, and seeing that the sky was gradually getting dark, Chen Guitang immediately issued a combat order.

The six heavy machine guns and six infantry guns of the machine gun company quickly began to set up positions, and Zhao Wei, the deputy battalion commander and company commander, personally commanded the position.

Six infantry guns aimed the muzzles of Hei Dongdong at the city gate of Pingding County, and Zhao Wei gave the order to fire.

Six grenades were shot out, and these six grenades hit the gate of Pingding County at the same time.
