When Yang Zhen said this, he saw that Lu Pinqi and Xia Chengde had troubled expressions on their faces, and immediately continued: "The main manpower to build the urn city at the south gate of the west gate is the troops under your respective command!

"I can call the Associate Camp Affairs Office here to allocate some spare manpower from other ministries to you for support, but you two have to be paid on a daily basis!

"Of course, the addition of the west gate and south gate urn city is not entirely your own business. After all, it is related to the overall situation of our Songshan, so the General Military Mansion will also subsidize you with some money and food!"

After saying these words, Yang Zhen said no more, but looked at Lu Pinqi and Xia Chengde, waiting for their statements.

Xia Chengde and Lu Pinqi looked at each other and couldn't think of a reason to refuse. Moreover, they had long wanted to build more urn city, but no one had made the decision.

Now it seemed that Yang Zhen had made up his mind. He not only pointed out the sources of materials needed to build the urn city, but was also willing to allocate some manpower to them and subsidize some money and food. In this way, they agreed after thinking about it.

Because in the final analysis, the construction of the West Gate and South Gate Urn City itself definitely has more advantages than disadvantages for their own troops. It can even be said that there are hundreds of advantages and no disadvantages.

"I will obey your orders!"

Xia Chengde and Lu Pinqi stood up together, clasped their fists and saluted Yang Zhen, saying that they obeyed, and they accepted the matter.

After these two people agreed, Li Lu, who was sitting among the people on the other side, suddenly stood up and asked: "Sir! Outside the east gate, there is no urn city, so it is understandable that you are in a low position. But the fort that your Excellency just mentioned is Songshan.

There is no precedent in the city, and I have never seen it in humble positions, so how should we practice the law?"

Yang Zhen had just convinced Xia Chengde and Lu Pinqi, and now he was very relaxed. When he saw Li Lu asking questions, he immediately said with a smile:

"Even if you don't ask, I still want to talk to you! Since you asked, I'll tell you all here! - The fort I asked you to build is not an ordinary fort, it should be on both sides of the east gate.

, according to the terrain, each building must protrude thirty steps outside the city wall, and it can only reach fifty steps!"

As Yang Zhen spoke, he turned around and took the tea bowl from the table. He squatted on the ground first, then dipped his hand in the tea and drew on the square tiles on the lobby floor.

And while describing it, he said: "The fort I asked you to build should protrude outside the city wall. It looks like this. Because of its sharp edges and corners facing the outside, we can call it a bastion from now on! - This is the bastion on the left side of the east gate.

, this is the bastion on the right side of the east gate!"

Yang Zhen dipped his hands in tea and quickly drew the appearance of the bastion he knew on the square tiles on the ground with his index finger.

Because the bastion drawn on the ground is just a flat shape, at first glance, it is actually just two rhombus-shaped quadrilaterals perpendicular to the east gate wall with the sharp corners facing outward.

Of course, Yang Zhen couldn't explain to these big bosses what a rhombus and a quadrilateral were. In fact, there were many types of bastions, and they didn't necessarily have to be triangles and four sides.

However, the so-called bastions he casually drew on the ground are more like the triangular arrowheads most commonly used in the army in this era. The two bastions outside the east gate are painted on the ground as if they were inserted into the city walls on both sides of the east gate.

two short arrows.

The arrowhead-shaped bastion has sharp edges and corners protruding outside the city. Only the root at the back is connected to the city wall of the east gate of Songshan. The fort above is equipped with one or several artillery pieces.

In this way, the depth of the city's defense can be greatly increased, so that the enemy's artillery array can only be deployed outside the range of the bastion fort, thus reducing the destructive power of enemy artillery fire directly hitting the east gate city wall.

At the same time, the contact surface of the bastion that protrudes outside the city is a sharp triangle with the sharp corners facing the outside of the city. When the enemy attacks the city, their heavy artillery cannot directly hit it.

The city wall cannot hit the wall of the bastion vertically.

Moreover, the bastion that protrudes outside the city wall can also allow the Manchu Tatars to suffer greater casualties when they dispatch infantry to attack the city. At least it can allow the Manchu Tatars to use the siege tactic of "cannon fire after the infantry charges" that the Manchu Tatars have just figured out.

Temporarily invalid.

At present, when the Manchu Tatars already have heavy artillery, in order to minimize the probability of the city wall being destroyed by heavy artillery when fortifying the city, Yang Zhen can only think of such a practical way to construct city defense fortifications.

It's a feasible way.

"You must carefully calculate the distance between these two bastions and the distance between them and the east gate city wall when the time comes! In addition, I have already requested cannons from the imperial court through Yang Chaojin, Eunuch Yang, the Superintendent of Ceremonies!

"The number of Hongyi cannons may not be very high, but you can still get some of the general cannons! Even if you can only get the Folan cannon, that's fine! You have to calculate the general cannons and Folan cannons.

The maximum range and effective range of the cannon, and then design the distance between the two bastions!"

Yang Zhen's words made Li Lu confused. Looking at the arrowhead-like bastion pattern on the ground that gradually faded and finally disappeared, Li Lu was confused.

He had followed Yang Zhen in the north and south for so many years, and this was the first time that he felt that the Yang Zhen in front of him was so strange. He heard every word Yang Zhen said clearly, but it seemed that he didn't hear anything.

Understand.

But at this moment, even Xia Chengde and Lu Pinqi had received orders. Li Lu, as Yang Zhen's confidant, naturally could not say anything more. He did not mention any demands at the moment, and immediately clasped his fists and bowed and said: "I humbly obey my orders!"

Yang Zhen also knew that with the few extremely rough sketches in front of him and the truth that he could not explain clearly, Li Lu, a contemporary person, might not be able to understand much.

However, whether we can really figure it out can be discussed separately. As long as we get started with the current matter, we can explore on our own in the process of building the bastion in the future.

Moreover, Songshan Minzhuang Camp Qianzong Anqing Hou had some masons available, including many masons and masons among the refugees rescued by Yang Zhen and others in Xiongyue City, and they could all be used at this time.

The military meeting convened by Yang Zhen in the lobby of the Songshan General Military Mansion did not end until nearly noon. In addition to unanimously approving the establishment of the Associate Camp Office, the military meeting also finalized the abandonment and demolition of all enemy towers outside the city and the construction of additional ones.

Matters concerning the two bastions of the West Gate Urn City, the South Gate Urn City and the East Gate of Songshan.

In addition, the peninsula bay area where Qiu Zhenhai's fleet was stationed was named Songshan Zhimao Bay by Yang Zhen, and the peninsula camp where their fleet was stationed was also named Zhimao Bay Ship Camp Water Village by Yang Zhen.

There are no decent islands off the coast of Songshan. The largest offshore sandbank is the one where the Jinzhou Sailor Camp was originally located.

At that place now, Yang Zhen arranged for Yu Liangtai's fleet to be stationed. There is already a camp built around several granaries at the highest point of the sandbank.

The Sailor Camp sandbank is surrounded by the sea and densely packed reed swamps, so it is relatively safe. Especially in this season, there is basically no need to worry about the sudden retaliation of the Tatars.

However, the peninsula where Qiu Zhenhai's fleet is stationed is different. They are connected to the land south of Songshan City. If we don't build a lot of construction and build fortifications, the soldiers will face the greatest danger in the future.

Therefore, Yang Zhen named the location of Qiu Zhenhai's fleet and told him to deploy his men as soon as possible after returning, dig deep trenches, and build earthen walls. It would be best to completely dig out the ground at the narrowest part of the Zhimao Bay Peninsula.

Artificially create an island surrounded by water.

Of course, the narrowest part of the Zhimao Bay peninsula named by Yang Zhen must be two or three miles wide. Although he has not actually measured it, if you think about it, you will know that this is a huge project.

Fortunately, the width of two or three miles is not an impossible task for the current Songshan City.

Because the ammunition factory in Songshan City can provide Qiu Zhenhai's Anchor Bay Chuanying Water Village with gunpowder barrels for making ten thousand enemies, the ground that is difficult to dig can be blown up first and then excavated.

Yang Zhen was not afraid that Qiu Zhenhai and the others would not be able to complete this task, because he knew very well that in the original history, the Manchu Tatar puppet emperor Huang Taiji once dug long trenches in the Tashan area in order to completely cut off the retreat route of the Ming army on the Songjin front.

This long trench dug by the Tatars stretched from the foot of the mountain in the west to the coastline, which was dozens of miles long.

Yang Zhen believed that what the Manchu Tatar army could do in autumn and winter when the land was hard, there was no reason why Qiu Zhenhai and his troops could not do it in summer when the land was soft.

As for the Sailor Camp sandbank where Yu Liangtai's fleet was stationed, Yang Zhen did not take it completely lightly. He also ordered Yu Liangtai to immediately arrange for men to dig trenches and build forts along the water level at high tide to build long-term defense fortifications after returning.

In the summer, the Sailor Camp is surrounded by water and has a large area of ​​dense reed swamps. Naturally, there is no need to worry about the heavy artillery and cavalry of the Tatars, but what about in the winter?

By then the reed marshes will be frozen, and the side of the Sailor Camp sandbank will be frozen. At that time, the Tatars' heavy artillery and cavalry will be able to advance forward, or even rush to the top. Without fortifications, it will be very dangerous.

Of course, both Yu Liangtai and Qiu Zhenhai immediately agreed to Yang Zhen's request.

After all, the lessons learned on Juehua Island more than ten years ago were too profound. At that time, a large group of Donglu Tatar soldiers took advantage of the once-in-a-lifetime opportunity of freezing the sea to gallop across the sea and rushed into the river without any precautions.

of Jue Hua Island.

The food and grass on the island were robbed, the houses were burned, and the population was completely killed. Juehua Island's years of management and savings were all snatched away by the Donglu Tatar cavalry.

At that time, people like Qiu Zhenhai, Yu Liangtai, and others were either serving in the Denglai Navy or the Dongjiang Navy, and they naturally had fresh memories of the accident that happened on Juehua Island.
