Sun Weiguo and Chen Yang used shell guns to shoot, and more than a dozen devil soldiers were easily dealt with.

After the more than 100 devil soldiers of the second squadron who charged were wiped out under the blows of the first and third companies, Sun Weiguo quickly issued an order to retreat, and the remaining thirty or so soldiers of the third company quickly followed behind the squad platoon leader and returned to the trench.

Sun Weiguo and Chen Yang are at the rear, the charge must be at the front, and the retreat must be at the rear, this is Sun Weiguo's requirement for the officers of the county brigade, only when the officers do these two points, the soldiers can completely trust the officers.

Under the cover of light and heavy machine guns and artillery, the troops of the third company successfully retreated into the trenches, and by the time Sun Weiguo and Chen Yang came to the trenches, the time was already more than five o'clock, and the sky began to be a little dark.

The Japanese puppet army troops were still advancing, even if the riflemen of the second squadron were completely annihilated, but they wanted to take the position in one go.

The puppet cavalry was less than 100 meters away from the trench, and the remaining more than 300 puppet cavalry cavalry had already begun to take out their rifles to shoot, and at the same time, the light machine guns and grenadiers of the four squadrons of the Japanese army had been gathered together, and there were more than 30 crooked light machine guns frantically strafing the trench here.

The Japanese heavy machine guns also began to cooperate with the puppet cavalry, and the nine heavy machine guns continued to fire bullets, and rows of bullets quickly attacked the trenches.

Light and heavy machine guns, grenadiers, mountain artillery, the Japanese took out all their belongings, and this time they were completely crazy, by this time they had been fighting for several hours, and the troops had lost two squadrons.

However, Kenji Suzuki put all his remaining three squadrons into battle, and if he wasn't worried that there would be problems with the artillery brigade, he would have directly transferred the fourth squadron, which was responsible for protecting the safety of the artillery brigade, to fight.

Sun Weiguo, who came to the trench, immediately inquired about the casualties of the mortar company, and learned that he had lost three mortars and more than 20 artillerymen, Sun Weiguo was very distressed, but the war is like this, you annihilate the enemy, it is impossible for you to have no casualties on your side.

The heavy machine gun company also had two Type 92 heavy machine guns destroyed, and the mortar company now has only four mortars, and the heavy machine gun company has only six heavy machine guns, of which two Maxim heavy machine guns are still deployed in frontal positions.

The troops of the third company were the troops with the heaviest casualties, and Sun Weiguo asked the reserve company to replace the garrison of the third company, and the troops of the third company were withdrawn to the village for rest and recuperation.

The first company and three platoons took over the defensive task of the rear position of the third company and eight platoons in Nanzhuang Village, and the first company and the second platoon of the first company were deployed on the trenches at the same time, and Sun Weiguo had already decided to withdraw to the second line of defensive positions.

The attack of the Japanese puppet army was fierce, and bullets and shells came as if they didn't want money.

The problem was even greater in the already battered trenches, which had been flattened by shells in many places.

Sun Weiguo glanced at the puppet cavalry who were constantly approaching the trenches, he hesitated for a moment, and began to give combat orders.

The heavy machine gun company, the first company of the grenadier squad, and the second company of the grenadier squad first withdrew to the second-line position, and when they withdrew to the second-line position, the light machine gun was responsible for covering the withdrawal of the troops into the second-line troops.

Because the second-line troops were the four heads of Nanzhuang Village, east, west, north and south, this was equivalent to compressing all the county brigades in Nanzhuang Village, and the defense range of the troops was reduced, but the lethality of the Japanese artillery shells increased.

Therefore, while issuing the order, Sun Weiguo made accurate arrangements for the second-line defensive positions.

The grenadier squads and light machine guns belonging to the three infantry companies were to remain on the second-line positions, and four infantry squads were deployed on the second-line positions to be responsible for defense, while the rest of the troops were to retreat to the third-line positions, and the troops of the three companies entered the tunnels to rest and stand by.

This also means that in the four villages of the second-line position, only one infantry squad of thirteen soldiers is responsible for the defense.

The rest of the troops were assembled in the third-line positions, but Sun Weiguo left behind the grenadiers and light machine guns and heavy machine gun companies of the three infantry companies.

Considering that the position on the right was the main direction of the Japanese army's attack, Sun Weiguo deployed three heavy machine guns, nine grenadiers, and nine light machine guns here, and the artillery squad also supported the operation here in the right position.

The remaining three positions were also deployed by Sun Weiguo with heavy machine guns, grenadiers, light machine guns and other firepower, of course, the remaining three positions were not the main attack direction, Sun Weiguo would definitely not also deploy such firepower as the right position, and the county brigade did not have so many light and heavy machine guns and grenadiers.

The troops began to withdraw to the second-line positions in an orderly manner, and at the same time, the troops began to carry out Sun Weiguo's orders.

The third company entered the tunnel to rest and wait, and the second company of riflemen began to assemble in the village fortifications.

Light and heavy machine guns quickly entered the second-line fortified bunkers, while the infantry hid in the houses.

In the blink of an eye, the troops were deployed, and now all they needed to wait for was the arrival of the Japanese puppet army.

Sun Weiguo was still in the right position, and the infantry squad defending here was a company, a platoon, and a squad.

The first squad leader was standing beside Sun Weiguo, and the company commanders and platoon commanders of the first company took the remaining troops to the third-line position to stand by.

Sun Weiguo's deployment is a typical defensive tactic used by the PLA in the War of Liberation, and light and heavy weapons are heavy in the front and heavy in the rear, and the strength of troops is light in the front and heavy in the rear, and such defensive tactics have obvious advantages.

When the enemy comes to attack, they will be violently attacked by light and heavy weapons on the front line, and after they break through the frontline position after paying heavy casualties, the large number of troops behind will launch a fierce attack, directly crushing or even annihilating the enemy who broke through the position.

You must know that it is very difficult to break through the positions of many light and heavy weapons, and the attacking troops will have to pay a heavy price.

By the time the enemy broke through the position, they would not be too numerous, but the defenders had a large number of troops.

Sun Weiguo is ready to use this defensive tactic to beat these little devils fiercely, of course, if Sun Weiguo's troops are doubling, he can completely annihilate this devil army without mobilizing peripheral troops.

"Signal troops, immediately go outside along the tunnel to inform the peripheral troops, once we have a battle with the Japanese puppet army here, the county brigade will try to entangle the Japanese puppet army, and the peripheral troops should take immediate action to attack the Japanese troops."

Sun Weiguo immediately gave an order to the communication soldiers around him, and the communication soldiers who got the order quickly agreed, and he began to convey the order.

At the same time, more than 300 cavalry of the puppet army had already captured the trenches, and the cavalry officer of the puppet army who led the team looked at Nanzhuang Village with a telescope, and his face showed an excited expression.

These puppet army officers did not know that the county brigade had taken the initiative to retreat, and they thought that the county brigade had suffered heavy casualties from the heavy artillery fire of the Japanese army and had to abandon the trenches.
