The Yangquan East Pass stronghold happened to be stuck between the Japanese occupied area and the Eighth Route Army Yangquan Independent Regiment.

In order to create a stable rear for the front-line sweeping troops and let them have no worries, the Yangquan Garrison stationed a whole Imperial Army with a strengthening squadron and a battalion here, with a total force of more than 600 people.

The Dongguan stronghold was even more like an iron barrel.

In addition to the central artillery tower, there is also a whole circle of machine gun castles surrounding it. All the artillery towers and castles are connected by traffic trenches to reduce the chance of troops being exposed to the ground.

Outside the castle, the Japanese army also built two circular positions in front and back, and connected the positions with transportation trenches to ensure that the troops can seize and abandon any positions at any time.

The unbreakable defensive position, the garrison of more than 600 people, a certain number of mortars and heavy machine guns... directly turned the Dongguan stronghold into a spike stuck in the throat of the Yangquan Independent Regiment of the Eighth Route Army, and it could not be pulled out even if it wanted to.

When the Japanese army gathered heavy troops to attack the National Salvation Army, the Yangquan Independence Regiment wanted to enter the Japanese occupied area more than once to reduce the pressure on the National Salvation Army to counter-sweep the pressure.

But the Dongguan stronghold was like an insurmountable iron wall, blocking the independent group in their base.

Now, in order to deal with the possible counterattack by the National Salvation Army, more than 600 garrisons in the Dongguan stronghold were directly transferred, with an infantry squad, an artillery squad, a heavy machine gun squad, and a company of the puppet army.

With fewer troops garrisons, the chances of Yangquan Independent Regiment conquering the Dongguan stronghold will be greatly increased.

Now the troops have two more mountain cannons and six mortars, and there are two thousand more shells in various types. The chances of troops capturing the Dongguan stronghold will increase by several%.

By this calculation, the Yangquan Independent Group is already more than 90% sure to take down the Dongguan stronghold.

At 10 o'clock in the evening, the Dongguan stronghold became particularly quiet as usual.

Except for the sentries and patrolmen, they still stood firm on the roof of the artillery tower and the castle, all the other Japanese and puppet troops fell asleep.

The first, second and third battalions on the combat power of the Yangquan Independent Regiment slowly touched the near the stronghold.

Under the cover of night, the Japanese guard post did not notice their existence.

Behind a ground beam more than 800 meters away from the stronghold, two mountain cannons just equipped by the Independent Regiment, two infantry cannons seized before, and two mountain cannons supported by the National Salvation Army were all placed on the top of the mountain ridge, and the black muzzles pointed directly at the stronghold.

A total of seventeen mortars were also placed on the flat ground in front of them, which were all the belongings of the newly established artillery battalion of the Yangquan Independent Regiment.

"Boom boom boom..." Six mountain cannons and infantry cannons fired at the same time, and seventeen mortars also joined the battle at this moment.

Whether it is mountain cannons or mortars, 800 meters are their best range.

More than twenty shells were like eyes, and all of them fell into the stronghold.

The fireballs that soared into the sky were like dazzling fireworks, blooming in an instant.

It took almost three seconds before the violent explosion reached everyone's ears.

The regiment commander could see clearly that at least three shells hit the edge of the central artillery tower and exploded. The dazzling fireball suddenly blew around the artillery tower like daylight, and it was clearly displayed in front of the regiment commander.

The Japanese guard post guarding on the roof of the artillery tower was shocked, like frightened rabbits, instantly squeezing behind the battlements.

Seeing this scene, the leader did not show too much happiness, but instead a hint of disappointment flashed on his face full of expectations.

Because the artillery tower, which poses the greatest threat to the offensive forces in front, is still standing in the middle of the stronghold without any damage.

His brows subconsciously frowned, and he was very dissatisfied with the order: "Continue firing, you must destroy all the artillery towers and castles in the stronghold!"

The highest-level officer left by the Japanese army was a captain. He got up from the bed with the sound of cannons. He grabbed the armed belt with one hand and the uniform with the other, and rushed out of the room in a hurry.

He has a lot of combat experience and you will know that the closest shells to him are less than thirty meters away.

If a shell hits the barracks and I am still in the barracks, I will definitely be buried in the ruins.

"Boom..."

Less than ten meters away, a violent explosion rang behind him. In the smoke of gunpowder, the barracks he had just escaped were instantly blown into a pile of ruins, leaving only a few ruins still standing strongly on the spot.

Cold sweat quickly flowed down the captain's forehead, and then he shouted with lingering fear: "Baga, it was too dangerous just now!"

"The troops gathered immediately, someone attacked the stronghold, and everyone entered the position and prepared for battle."

The captain said as he rushed towards the nearest traffic trench to him.

Several barracks had been destroyed in the fierce artillery fire, and none of the soldiers living inside ran out and were buried in the ruins.

Although the soldiers in other barracks rushed out of the barracks alive, everyone was in a particularly embarrassing manner. Some were not wearing military uniforms and some did not hold guns, but their goals were the same: they rushed out of the barracks and ran towards the nearest traffic trench to them.

"Boom..."

The shelling of the Independence Regiment continued, and the mortar shells seemed to rain, constantly hitting the open space of the stronghold.

Many Japanese and puppet troops were about to rush into the traffic trench when they wanted to see it, and a shell hit them just in time.

In the splashing flames, these Japanese and puppet troops suddenly turned into paper toys and were instantly bombed into the sky.

The captain was very lucky that no shell hit him until he jumped into the traffic trench.

In addition to being lucky, I immediately ran towards the artillery tower along the traffic trench.

There is the commanding heights of the stronghold, and you can see the surrounding one kilometer.

But the goddess of luck did not visit him tonight.

As soon as he rushed to more than 20 meters outside the artillery tower, a more violent explosion suddenly rang in front.

The traffic trench can help you block the flying shell fragments above your head, and cannot block the powerful air waves generated by the explosion of the shells.

The captain felt that he was pushed hard by a powerful force, and his body was uncontrollable, and he fell on his back in the trench.

Before I could get up, the artillery tower in front of me collapsed.

The artillery tower that had been hit by more than ten artillery shells in a row finally failed to support the continuous destruction of the artillery shells, and the sound of "boom..." turned into ruins.

The captain's face showed a look of fear again. If he had just run faster and entered the artillery tower, he would have been crushed in the ruins at this moment, and his life and death would not be confirmed.

The artillery tower could not be reached, so the captain had to retreat and run towards the nearest machine gun castle.

The enemy's artillery fire is very fierce, and staying in the castle is definitely much safer than being exposed to the fire. Only by rushing into the castle as soon as possible and saving one's life can you have the opportunity to understand the enemy's situation, make a correct judgment, command the troops to repel the enemy's attack, and defend the stronghold.

Otherwise, after your life is lost, other things will be free of discussion.
