The continuous bombardment of the infantry artillery scattered the bricks and stones held on the walls on both sides of the opposite city gate.

The rammed earth city wall of Fuzhou City is covered with bricks and stones, because of the long construction age, and the inability to renovate after the arrival of the Houjin, there are many places that are not well maintained, and the masonry has automatically collapsed and fell off, leaving only the rammed earth wall, which is very beneficial to the excavation work of the Huaxia army.

After waiting for a while, after the smoke and dust had cleared a little, as a military horn sounded, the soldiers of the first battalion of infantry who were shooting at the front and the rear Jin army on the city wall increased the frequency of their shooting.

The shield carts, which were located on the two wings and did not cover the task, began to cross the river one after another from the erected trench wagons.

As in the frontal direction, behind each shield car crossing the river, half a squad (a combat group) of Chinese infantry was followed.

The infantry riflemen who were responsible for the cover task behind the second row of shield cars shot more and more fiercely, hitting the Wuzhen Chaoha clothed soldiers on the wall, and the soldiers of the Eight Banners screamed again and again.

Even the strength of the counterattack slowly weakened, and the feathered arrows and lead bullets shot gradually thinned out.

The shield carts that had crossed the river stopped a few paces away from the city wall, and several triangular caravans made of sturdy logs rushed straight up and pressed against the city wall.

The coated captives, who were hiding under the caravan, began to dig up the roots of the wall under the supervision and suppression of the gendarmes who followed.

When the Houjin Tartar officers at the head of the city saw this, they immediately got busy, and they let out a fierce shout, and drew their swords to threaten the soldiers to fight back quickly.

Unfortunately, there were no heavy weapons controlled by ropes, such as poles and rolling logs, where several caravans were located, and the soldiers of the Houjin Army could only throw stones and clods of soil below one after another.

These fragments and untidy debris smashed on the caravan at once, and the car kept making "bang bang ······" The ringing of the sound.

Fortunately, the top of the caravan was specially made into a triangular shape according to the records of the military records, and this angle has a good unloading effect on the stones, sassalwoods and other things falling from the sky.

There are still many sieges and battles on the roof of the "Armament Chronicles" are shot like this, so many equipment of the same shape is enough to explain the benefits of this type of protection.

The movement on the roof of the car, the coated captives could hear it, and the coated captives who were hiding in the caravan were all nervous and sweating constantly.

This caravan was made by several special officers of the Huaxia Military Engineer Company who worked overnight, and they had never made it before, so they didn't have any bottom in their hearts.

Fortunately, there are gendarmes pressing the formation, urging them to work, which can divert their attention to a certain extent.

At the urging of the gendarmes, the coated captives kept their heads down, and desperately dug the opposite city wall with shovels and shovels in their hands.

The first is to take out the bricks of the loose and cracked city wall that have been beaten by the infantry artillery, and then immediately begin to excavate the rammed earth layer behind the bag.

If the outer layer can be repaired and maintained in time, these rammed earth layers can still be retained, but after all, the city wall is very old, and the Houjin Army is not well maintained, so the layer that is close to the bag is quickly pulled down easily.

But it is only the outer part of the outer ring that has been eroded by rain through the damage and brick joints that is better excavated.

Wait until the outside is pulled down, and some of the rammed earth walls inside are difficult to start.

Because the rammed earth wall inside has been carefully tamped through multiple processes, its back has already been pressed very tightly, to the extent that it is as solid as iron and stone, and a shovel can only dig down a small piece of soil down.

Zachdan was on a hill in the distance, watching his own movements with a telescope under the southern wall.

When he saw that it would take a long time for a basket of dirt to come out of the caravan, he couldn't help frowning, turned to the combat staff officer beside him and asked, "Haven't you done experiments?" Have you simulated this tactic of digging walls? How do I remember that the report at the time said that the excavation was progressing very quickly? ”

The staff officer was also at a loss, and when he heard Zachdan's question, he thought for a while, and replied cautiously, "It may be that when our army was conducting experiments and verifying the feasibility of tactics, the materials used in the rammed earth wall were different from the current ones.

The subordinates guessed that the soil composition here should be harder than the soil where our army's experimental area is located. ”

Another staff officer also asked in a skeptical tone, "Could it be that it has nothing to do with the hardness of the soil, but because the coated captives are lazy and don't work well?" ”

The staff officer who was the first to answer Zachdan's question shook his head firmly, "Impossible, those coated prisoners are now under the threat of the enemy's rolling stones and woods, and now they are really afraid of being stoned to death, so it is definitely not that they are deliberately delaying time."

Moreover, there is the most important one, beside the coated prisoners, there are also our military police units supervising their work, and I absolutely believe in the firm will and rigorous work style of our military police. ”

Zachdan agreed with this speculation and explanation in his heart, but he couldn't show a good face now, because the speed of the excavation in front of him really made him anxious.

Zachdan, who put down the binoculars, groaned for a moment and ordered, "After I go back, I will go to the military department as a training department and ask them to conduct other experiments and training syllabuses related to siege tactics."

Every time we attack a city, we use captured coats and prisoners, which is not a long-term solution after all. We have to develop our own strengths, or killer features."

With that, Zachdan raised his binoculars again and observed the situation on the battlefield.

Suddenly, an officer seemed to remember something, and said, "Commander-in-chief, my subordinates remember, the engineer unit didn't carry out explosions!"

Last time, when the rebellion was suppressed in China, I encountered some tunnels built with cement in the cottage, and the thick cement slabs at the bottom could not be opened, and finally I found some masters of the engineering unit to blast, and blew up the tunnel buttons, only to find the exit on the other side and catch the bandit leader.

Before his subordinates left the country and came to our brigade to take up their posts, they had heard that the men of the armed guard unit had already sent personnel to the engineer unit to learn the means of blasting.

Now that my subordinates think about it, if there are people in the engineer company directly under my brigade who know this craft, wouldn't it be better to let the soldiers of the engineer company dig holes and blow up the city wall than this kind of rat-digging tunneling tactics! ”
