All the Japanese troops in Xinzhuang were basically shrunk in the courtyard, and the preparatory battalion bombarded the courtyard wall with war defense artillery, and the defense system that the Japanese army relied on collapsed.

After the preparatory battalion entered the battle, the situation on the battlefield was irreversible. Zhang Wei took the flower trap and fired at the door in front of him, replaced it with a new magazine, and the soldiers next to him threw grenades into the house, and the explosion blew out two corpses that had been beaten into a sieve by the flower trap.

In the close-range melee, the grenadiers in the hands of the Japanese soldiers completely lost their effect, Zhang Wei followed the soldiers forward in the direction of the second company, and after the battle for the peripheral houses, the soldiers of the preparatory battalion had accumulated a lot of experience, light machine guns and rifles fired first, and grenades opened the way.

Amid the sound of the explosion, the three companies of the preparatory battalion continued to advance, encircling the Japanese troops in the courtyard in three directions, and constantly compressing the houses under their control.

The main firepower of the Japanese army now is only a few Type 92 heavy machine guns, which formed a fire network in the flat part of the courtyard, which at first killed and injured many soldiers of the reserve battalion, but then the soldiers of the preparation battalion avoided the fire net of the Japanese army.

The three infantry companies of the reserve battalion could completely shrink and move closer to avoid the heavy machine gun fire of the Japanese army, and the role of the Japanese machine guns was greatly reduced.

The infantry of the reserve battalion could be quickly transferred, but the heavy machine guns could not.

Zhang Wei and the second company acted together, and captured the Japanese houses one after another, and the Japanese army's heavy machine gun fire was ineffective, and the only way was to fight with the preparation battalion room by room.

The two armies tried their best, the Japanese army wanted to hold it, the preparatory battalion wanted to fight down, although the Japanese army's defensive zone was constantly compressed, but after all, they had high fighting quality, and the preparatory battalion could not be eaten for a while.

"Battalion commander, it's hard to push inside, the little devil's heavy machine gun is useless, but there are too many light machine guns." Mu Chao said.

As the saying goes, the trapped beast is still fighting, which is in line with the mood of the Japanese army now, these large courtyards were opened up by the Japanese army in advance, connected together, and the prepared battalion rushed in quickly, and took down a lot of houses guarded by the Japanese army, and the Japanese army was not vegetarian, and saw the houses controlled by their hands, and the area of holding on was getting smaller and smaller.

The Japanese army was also ruthless and desperately defended it.

The Japanese armed with light machine guns, rifles, and grenades to control the core of the compound, and most of the perimeter and access roads in the compound were controlled by the preparation battalion, but it was too difficult to fight inside.

Now the offensive and defensive situation map of the two sides can be seen as a circle, the reserve battalion occupies three-quarters of this circle, and tries to continue to expand to the center of the circle, the Japanese army guards the inner circle, desperately resisting the attack of the preparation battalion.

"Tell the brothers to hold on, now there is no other way but to fight!" Face-to-face, face-to-face house battles.

The soldiers of the preparatory battalion and the Japanese soldiers are likely to be only a few dozen centimeters apart, and this kind of life-fighting battle can only be desperate and play with their lives.

The sound of "boom" explosions sounded, and suddenly grenades flew out, some hit the houses, and some smashed into the yards, and the Japanese troops were forced to be in a hurry, and they even used grenadiers, and in a small space, it was impossible to accurately judge the enemy's situation, and most of the people were in the houses step by step, and even people could not see clearly.

In order to recover the declining situation, the Japanese army actually used grenadiers to engage in blind shooting and threw grenades outward.

"Mu Chao, the devil is playing with his life, hit the main grenadier, you go and ask the brothers to mount light machine guns on the house and block them!"

"Yes!" Mu Chao went down to organize the manpower, and the Japanese used grenadiers to throw grenades outwards and suppress them, so they had to let the machine guns go up to the room and fight condescendingly.

"Hurry up, two light machine gun crews, climb up to the house!" The two turntable light machine gun crews that received the order quickly got out of the house, and with the assistance of other soldiers, found ladders, climbed to the roof, quickly set up machine guns, and changed the ammunition discs.

The light machine gunners judged the general direction based on the tail smoke fired by the Japanese grenades, held on to the trigger, and opened fire in the direction of the Japanese grenades.

After a round of gunfire was fired, the Japanese grenadiers could not carry the machine gun shells and were forced to stop firing, and the soldiers of the preparatory battalion continued to attack inside.

Qiu Wei's first company was on the left flank of the second company, and when he saw Mu Chao's second company's light machine gun going up to the room, Qiu Wei did the same and called his soldiers to go up to the room to attack.

The heavy machine gun assigned to the first company before the war was also pulled up, and the machine gun team only carried the body and bullet box of the heavy machine gun, mounted the heavy machine gun on the beam of the house and opened fire.

The continuity of fire from heavy machine guns and light machine guns was not at all an order of magnitude thing, and a series of heavy machine guns fired at the houses occupied by the Japanese troops, firing hundreds of rounds, and many Japanese soldiers were hit by machine guns in the houses and could not return fire.

The windows and the sturdy wood were smashed by a dense barrage of machine-gun shells, and a company of soldiers climbed up the beams of the roof and fired grenadiers at the beams in the same way as a man.

There are six ** grenadiers in a company, it is convenient to observe on the beams of the house, and the people who operate the grenadiers are veterans, observe the places where the Japanese troops are hidden, and immediately open fire, and shoot the grenadiers on the commanding heights, which is much more convenient than the Japanese troops fighting below, and the grenades are thrown along an arc, from high to low on the houses with Japanese garrisons.

Some grenades fell on the house, the grenade of the heavy grenadier is not small, it explodes on the roof, it can blow up a small hole in the roof, the tiles on the beams of the house are blown away, and there is a secondary kill, which increases the power of the explosion of the grenade, the broken tiles become shrapnel, the Japanese soldiers hidden in the house are no longer safe, and the tiles scattered everywhere hit the Japanese soldiers, but they will not kill immediately, and there are continuous screams in the room.

Part of the soldiers of the first company threw grenades, grenades and grenadiers on the beams of the house after a meeting of grenadiers, and together with the machine guns fired on the beams, the Japanese defense was beaten into a pulp.

"Battalion commander, a company of fierce fighters over there!"

Zhang Wei also saw the burst of firepower of the first company, which was the only one of the three companies in the battalion with a grenadier canister, and there were relatively many veterans, and the role of the elite company was fully revealed at this time.

"Mu Chao, attack it!" Now that the Japanese army has been suppressed, Zhang Wei ordered to organize a strong attack, and soon made a breakthrough, and the first and third companies also launched a surprise attack, and finally attacked the core courtyard guarded by the Japanese army.

The preparatory battalion attacked from three directions, and there were no troops in the rear, but the Japanese commander was not slow to react, seeing that the preparatory battalion had completely broken the last defensive system, he quickly organized a retreat, leaving behind all the heavy equipment.

Except for the Japanese troops who were stuck with the preparatory camp, all the other living forces that could be brought rushed out from the rear of the courtyard.

The gunfire continued, and the Japanese troops who were glued to the prepared camp were still resisting, and the Japanese soldiers who ran out from the rear of the courtyard blew the wall with grenades and fled.

"The devil wants to run!" The Japanese army ran out, and many people saw it. Some soldiers wanted to turn their guns, but they were stopped by Zhang Wei. Outside the Zhuangzi, there are chariots waiting for them.
