Chen Xin thought for a while, and finally decided: "You are responsible for this matter, and you make your own assessment and make the final choice."

It's just that there is one thing, if he is allowed to stay, it will not allow him to come into contact with the secrets of our army, and the personnel can be temporarily placed in the military intelligence bureau to serve.

During the period in Lushun, this person must not enter the southern city of Lushun, just outside the city, and when he wants to go out of the house for activities, he must be blindfolded.

Also, it's better to ask more about him, this guy used to be the white-flaged Baga Lazhen. It should be known about the specific situation of many white-armored soldiers, and after the interrogation is out, they will all be handed over to the military department in time. ”

"The subordinates understand, they must act according to the instructions of the king, and they will never let Moncta take advantage of it!"

Chen Xin looked in the direction of the flank along the moat in the southern city, and the protruding horse faces made him feel that this place was even stronger.

This kind of horse face has been proven many times in history to greatly increase the firepower of the flanks, so that the dead angle under the city is greatly reduced.

This improvement of the shape of the horse face is based on the slight construction of the old city wall of Lushun South City, and it is still a convex old defense facility on the whole. In terms of defense, it can't compare to the Bastion.

In the original history, the more prosperous bastions were concave in shape, with almost no dead ends, giving the defenders a great advantage. In the late Ming Dynasty, this method of construction also spread to China.

Xu Guangqi once suggested the construction of a three-layer triangular hollow enemy platform in Jingshi and Jizhen, and for the first time had the concept of an acute angle defense line.

Later, Sun Yuanhua learned in more detail, and in his "Diagram of the Stage", he clearly proposed the construction of an acutely angled defense line, which he described as "shaped like a long claw." to save each other", is the shape of the outer wall of the fortress formed by multiple acute angles.

Unfortunately, although he was sent to Ningyuan to assist Yuan Chonghuan in building the city defense, with the decadent atmosphere of the Liaodong military town, these improvements of Sun Yuanhua could not be truly realized.

Sun Yuanhua's forts were not self-studied, they were all from European missionaries, and the Macao mercenaries were more professional than the missionaries, and the Portuguese forts they built in Macao were the first Western forts in the Far East, and many of these methods were also transmitted to China.

When these mercenaries were instructors in Dengzhou, they did not play this role, because Dengzhou did not have the urgency of being attacked, but after the Dengzhou Rebellion, the Huaxia Army took the opportunity to take over this group of mercenaries in Shandong.

The people of the Huaxia Military Department invited them to the lecture hall to systematically teach this knowledge, and a number of Francoix officers were sent to the fortifications in various parts of Huaxia to assist in the construction of defense lines.

Now the Huaxia Army has established a lot of credit for the earthen wall system established in Lushun.

However, the Huaxia army did not use the fortress in Lushun City.

Although the defensive facilities of the horse face are not as powerful as the defensive function of the military fortress like the fortress, the horse face also has an incomparable advantage of the fortress, that is, the urban function that the fortress cannot have.

In addition to fighting, the interior of the fortress could not accommodate the lives of civilians, and the fortress was completely a military fortress.

The defense facilities of Mamian are built on the basis of the square city wall with the function of the city, and in addition to enhancing the defense function of the city, it has no impact on the lives of the residents in the city.

Lushun is not only a defensive fortress, but also a springboard for the Huaxia Army in the Liaodong region, and the largest material transit base.

Only by allowing Lushun to continue to expand and prosper can it be possible to support possible expeditions in the future.

After passing through the southern city, there is the area of the defensive line where the second earthen wall is located, and there is about 100 meters of flat ground between the earthen wall and the city wall, and a moat 6 meters wide.

Behind the earthen wall, now sitting were the infantry of a battalion of the 11th Infantry Brigade, who had been on standby in this place, and the gaps in the reserved gun emplacements beside them were empty.

If the Huaxia Army abandoned the first earthen wall, the artillery in front of it would be quickly transferred here to continue to defend the attack of the Houjin Army.

On this earthen wall, at intervals, there is a raised surface in the style of acute angles, and in front of it there is a deep trench 6 meters wide, under this defensive system, any means of attack will eventually face the resistance of this trench.

The second earthen wall is completely different from the first earthen wall, there is no such low breastwork wall behind the trench, and once the enemy crosses the trench, he will be directly confronted with a rammed earth wall more than 3 meters high.

When I walked over the thick wooden planks that had been erected in advance on the trench, I deliberately glanced into the trenches on both sides, and I could clearly see that it was covered with various sharp wooden stakes.

According to the plan made before, when the enemy attacked, the defenders would temporarily sprinkle patches of thistle terrestris, and even fire oil, in short, this trench was a Jedi.

After walking through this deep trench, the first earthen wall appeared in front of Chen Xin.

The smell of gunpowder smoke filled the surrounding air, and the sound of cannons was like thunder, as if it were exploding around everyone.

Powerful passwords rang out one after another, and the sound of the infantry cannons on the earthen wall was like fried beans.

Under the strict training system of the Huaxia Army, this kind of smoothbore infantry cannon with a small caliber is also extremely powerful, and now, the number of infantry guns that are deployed in Lushun is as many as hundreds, which can definitely play a huge role.

There is more than 100 meters of flat land between the two earthen walls, and the reserves and artillery of the Chinese Army can be quickly mobilized behind the earthen walls, whether it is support or retreat, it is very easy.

On the inside of the earthen wall, there is a relatively gentle slope, and the warriors can easily climb the wall from any place to fight.

At this time, most of the people on the wall were ordinary riflemen, and those elite troops who had been assigned advanced weapons were all sitting in the open space in front of the base of the earthen wall, quietly waiting for the order to arrive.

There are also the medical soldiers who are the easiest to calm the morale of the army, and they do the same, and they have no intention of hiding in the city without the slightest fear of danger.

Everything of the Huaxia Army on the battlefield was well organized, and there was no place that did not show the style of the Huaxia Army's professional army, which was different from that of the feudal era.

Chen Xin looked at all this, and there was only pride in his heart. He is proud of himself for laying such a foundation, and he is also proud of this revolutionary army.
