The ridge in the north of Guangxinfucheng City is divided into two parts: the main fort and the outer fortifications.

The main fort is an equilateral pentagon, with a protrusion similar to the tip of a long spear on each corner. The key to distinguishing the prism from an ordinary city is here, because this protrusion can provide more shooting surfaces for the defenders, and when the attacking party attacks this protrusion, it will also be attacked by the walls of the pentagonal main fort on both sides.

This kind of bastion has a shooting dead corner, which is the two sides that are closest to the outside of the protrusion. This dead corner cannot obtain fire support from other directions when attacked like other city walls, and they can only resist it themselves.

However, these two sides are the outermost corners of the main castle of the bastion. They are generally made of stones, and the focus surface is oblique and the anti-aircraft attack ability will be stronger. In addition, this protrusion is not integrated with the main castle. Even if the protrusion is captured, the defenders can still continue to defend with the concave walls in the area.

In addition to the main fortress, the outer fortifications of this basin include a Half Moon Fort covering the main fortress wall, and a moat surrounding the main fortress and Half Moon Fortress. The outer edge of the moat also keeps rising in the direction of the basin so that its firepower can more perfectly suppress the opponent's impact slope. In addition, there are also Chinese and Western defensive facilities such as wooden stakes and low walls on the outside, which is a hodgepodge.

In this way, if you want to attack the main fort, you must first demolish the most outer defense facilities, and at the same time carry artillery fire on the impact slope to fill the moat. After the moat is filled, you will take down the Banyue Fort under the artillery fire of the Banyue Fort and the Main Fort, and then fill the moat of the main fort. As for the suspension bridge between the Banyue Fort and the Main Fort, it is impossible for the defenders to let go.

Next, when the moat is filled, you can attack the main fort. However, directly attacking the main fort wall requires the attack of the protruding parts, so you have to try to take down the protruding parts and then try to break through the concave fort wall inside the protruding parts to attack the castle.

In short, after the attack of this bastion, it was subjected to multiple angles throughout the whole process. Even if it was done every step, it would have to die several times or more than ten times the defenders. What's more, with the current tactics, it was a dream to capture it. Therefore, Zheng Chenggong and Kangxi later chose to use hunger to capture the Dutch and Russians like the Europeans.

From this, it seems that the tactics that Tian Xiong had used before seemed to be more creative...

The Anhua Town Bastion, Hulu Town Bastion and Lishui Castle built by Chen Wen had the prototype of later star-shaped castles in their designs. However, he was also a second knife himself, and he had not recorded a lot of European-style bastions, such as the Banyue Fort, impact slopes, and protrusions, and did not use the method of piled up soil to form mountains to reduce the height of the fort wall to reduce the vibration of the fort when the artillery was used, and to absorb the kinetic energy of the shells with the high soil.

Fortunately, Chen Wen absorbed some skills in building Chinese-style city walls and greatly strengthened the exterior wall of the castle. In addition, he had already had the prototype of a more advanced star-shaped castle. With the Qing army of this era, even the Han Eight Banners Army of Hotan Xiong, who was stationed in Hangzhou in the hands of the Han Eight Banners who followed Huang Degong to cut off bandits, there was no way for her to do anything about her.

James believed that Chen Wen had not learned well in the borough, and Chen Wen could not like this Jesuit priest. It was not that we were like Tashi who was talking every word. This guy probably saw too much in Beijing, so he despised him. He didn't have the same knowledge as this guy, but every time he showed off, people always seemed to make people hear something like "I'm better than you, so you can't kill me, you can only offer me. I think you can do it on demand for God's sake" and it was really disgusting.

"This red barbarian probably treats us as ignorant as Tartars. This time, let him know that our Ming Dynasty is not without talented people."

Zhang Gongyan was the staff officer of the Army Staff Office, while Zhao Qian was Chen Wen's chief military engineer. He had previously built the Hulu Town Bastion and Lishui Bastion, especially Lishui Bastion, which contained some of his own experiences. For example, designing the moat with slopes, then planting grass on the slopes, laying pebbles, and finally laying caltrops in the grass and among the stones...

At this moment, Zhang Gongyan and other staff members were discussing with engineer officers led by Zhao Qian, so as to better implement Chen Wen's will to those engineer officers of lower level.

After staying for a long time, these officers had a comprehensive understanding of how they and the troops they were in needed to work, and returned to their respective troops, organized the engineers and the assigned auxiliary soldiers to start their "attack".

……………………

On the top of the castle, Jiangxi Admiral Liu Guangbi and Guangxin Mansion General Bu Shilong immediately rushed to the top of the city after receiving the incoming sentry.

As far as I see, except for the fort wall in the front of the capital city, there is no Half Moon Fort, there are other directions of Half Moon Fort. After entering the Changwei, the Ming army began to dig soil on the ground. It seems...

"Military Gate, the Ming army outside the city is planning to dig tunnels to let go of the collapse method."

"Relax?" Liu Guangbi looked away from a distance before turning to say, "It looks like it really looks like it, and there is probably nothing else to do."

Hearing this, Bu Shilong couldn't help but breathe a sigh of relief. "That's good, this bastion is so crafted that when it is built, the fort was also dug into the ground holes, so that a few blind men can listen there. Then, we can fill in the soldiers in the tunnel of the Ming army, so that we can speak harder."

Bu Shilong and his subordinates, like Jingbiao's Five Towns, were all Green Camp soldiers transferred from the north. However, Hong Chengchou hollowed out the warehouse in Jiangnan and trained that army. The city-guarding troops like Biaoying in Guangxin Mansion were destined to be separated from the Spanish phalanx. In the previous three confrontations, the Ming army defeated the Qing army and broke the city, Liu Guangbi even fled into the bastion with more than a thousand subordinates.

There was a sudden one thousand holes in the bastion stationed in the 3,000 Qing army, and the food would inevitably become more tense. However, they had lost the confidence to fight with the Ming army and were afraid to break through, especially without the cooperation of the cavalry, they could only live here for the time being.

There was basically no need to think about reinforcements. Bu Shilong watched Liu Fangming take the remaining thousand cavalry in with his own eyes. The only way was to stick to it. When the Ming army was bleeding but still unable to break the city, he would negotiate with Chen Wen to at least protect the lives of them.

Liu Guangbi said this to his defeated generals, and he also said this to Bu Shilong, and Bu Shilong also said this to the soldiers of Guangxinfu Town Biao.

Liu Guangbi knew that he would die, so he tried his best to persuade his subordinates and Bu Shilong. His subordinates also gained a lot in the massacre of the city in Yongfeng County. Those who followed him into the battalion were basically beneficiaries of the front and rear camps, which can be said to be a relationship of prosperity and loss. Liu Guangbi relied on his own basic foundation to convince the hesitant Bu Shilong. Next, Chen Wen's killing against the Nanchang shogunate and the evil murderers also endorsed his words.

"Brother Bu, our wealth, life, wealth and glory are all pointing to this bastion. As long as we keep here for a while and force Chen Wen to no avail, we will always have the opportunity to use this bastion for better conditions. At that time, even if we go back, the court will also record the credit we once gave Chen Wen to pieces!"

“That’s right.”

Since he had seen the Ming army's tactics, Bu Shilong hurriedly sent someone to pass the orders, making the personnel in charge of Weng Ting nervous, so that the Ming army could take advantage of it.

From a distance, the Ming army's excavation speed was not slow, but it would take some days to dig it up. Seeing that there was nothing wrong for the time being, Liu Guangbi and Bu Shilong returned to Bu Shilong's general's mansion in the castle. It is the same thing to share the joys and sorrows with the soldiers, at least there is still entertainment. For example, if you get together to drink some wine, let the singers in the female camp dance, sing a song, and then pick a few warm quilts that you can see, which is also excellent.

After drinking some wine, the two of them naturally had to complain. Hong Chengchou was dead, but it was only a few days ago and his reputation was still somewhat, so those involved in Hong Chengchou were generally skipped by the two subconsciously using excuses such as "misbelieving in others' words". As for whom he misbehaves, it is self-evident.

"When I mentioned the red barbarians, I heard someone killing people in the east a few days ago. There was no such guy from the old manager to the officers below. I think it was Chen Wen who sent him to the counter-espionage plan."

When training in Nanchang, the Spanish phalanx had a very good effect, and it was also good when they first fought with the Ming army. However, when the decisive battle, the dense phalanx became a target of slow action. Chen Wen used the dense phalanx to achieve a turnaround, making them as frustrated as they were.

In fact, the brink of the brink of the monks from the Jesuits was also designed and built by the monks from the Jesuits. However, the monk was very kind to deal with people and was very polite to them, the Qing army commander, not like this James. Of course, if they knew that James had already mistook the designer of the brink of the brink of Chen Wen in order to make things easier, they probably had to uphold justice for worldly justice.

Hearing this, Liu Guangbi quickly waved the singers and lowered his tone and said to Bu Shilong: "I listened too. The old master, Admiral Bai and Huang Fantai were all killed. However, Admiral Li, Admiral Liu and Hu Daotai and others were not executed by the Ming army like the red barbarians. They probably escaped."

As soon as this said, Bu Shilong immediately looked disdainful. "We don't know Admiral Li and Hu Daotai, but Liu Fangming, brother, I watched him leave with my own eyes. I haven't seen him send someone back to inform me these days. I think he would have escaped without a trace. If it weren't for this, the long encirclement of the Ming army outside the city would not be so easy to build. He still has thousands of iron cavalry in his hand."

If there is cavalry cooperation, the battalion will only be more solid. This is the most basic principle, and the same is true for ordinary cities. Bu Shilong doesn't believe that Liu Fangming doesn't understand at all, but according to him, this guy probably ran far away. Because the long encirclement was together, the traffic inside and outside the city was cut off, so naturally there was no need to talk about cooperation.

"That's true. I think this guy doesn't rely on Pan'er the most."

……………………

While Liu Guangbi and Bu Shilong were drinking wine in the basin, Liu Fangming, who was "not relying on pan" had already arrived at Raozhou Prefecture City on the east bank of Poyang Lake.

Raozhou Prefecture City is located in Poyang County in later generations, and is about 300 miles away from Guangxin Prefecture. However, Liu Fangming is surrounded by cavalry. After the first day of desperate rush and the morale decline in the next few days, he finally arrived at the military transport and ship manufacturing center of the Nanchang Shogunate today.

"How could this happen?"

In the prefectural office of Raozhou Prefecture City, Raozhou Prefecture Zhang Daocheng and Poyang Prefecture Hao Zongfu listened to Liu Fangming's story in amazement. They had already learned about the Qing army's failure in Yushan County, and even a large number of newly arrived military supplies were shipped with Hong Chengchou back to Guangxin Prefecture. Now it seems that they all have to be cheaper than the Ming army.

During the deployment of Guangxin Mansion by Hong Chengchou, the powerful general Hu Maozhen was originally responsible for the cavalry. Unexpectedly, Hu Maozhen died in the Ming army's phalanx on the first day of the siege and left behind many Qing cavalry.

Fortunately, the Qing army had a lot of cavalry. Twenty percent of the original 35,000 troops were cavalry, with a total of 7,000 people. After Yushan and the large number of casualties on the first day, Hong Chengchou still brought together the cavalry including Guangxinfu Zhenbiao and other cavalrymen, and handed over this cavalry that was still more numerous than the Ming army to Liu Fangming to continue to restrain the Ming army the next day.

Unexpectedly, Liu Fangming learned from Hu Maozhen's lesson and did not act recklessly, but the city could not be defended. He fought hard at the critical moment, but it was useless. In the end, he was fled from the battlefield by the defeated soldiers who were temporarily transferred to him.

Liu Fangming was not a powerful general who was known for his bravery like Hu Maozhen. He was a general who used troops to seek stability and was good at judging the situation. In Ningxia, Hong Chengchou gave his cavalry to him for restraint because of this reason. However, such a character was far less than that of Hu Maozhen, who could conquer these temporary subordinates. The city was captured and the soldiers were as collapsed, and he was powerless for a while.

In the past few days, he has worked a lot of effort to stabilize the morale of this army for the time being, but it is difficult to fight again. At this moment, Zhang Daocheng asked him what he should do, and Liu Fangming said intently: "Who do I want to ask!"

However, although Zhang Daocheng and Hao Zongfu are both members of the Nanchang Shogunate, they are just civil servants. They are obviously in a mess here, and only he can try to make this big idea.

"It is obviously impossible for the old master to escape. For the sake of the present, there are only two ways to go."

"The plan will be released?"

Hearing this, Zhang Daocheng grabbed Liu Fangming's sleeve, as if he was holding on to the last straw.

"First, use the ships at the dock to load all the military supplies, supplies, soldiers and families of Raozhou and transport them to Nanchang. The city of Nanchang is strong. When Taizu of the previous dynasty had not won the world, the ancestor of the Jingjiang vassal once guarded there and dragged Chen Youliang's hundreds of thousands of troops. It was one of the few strong cities in the world..."

What Liu Fangming said was that Zhu Yuanzhang's nephew Zhu Wenzheng was guarding Hongdu. The victory of this war laid the foundation for Zhu Yuanzhang to unify the south, so Zhang Daocheng and the others naturally knew. However, since Chen Wen opened the door to Jiangxi, Nanchang was his must-have, and it seemed that it might not be very safe.

"What about the other one?"

"Secondly, take advantage of the Ming army's failure to block Poyang Lake and sail into the Yangtze River. We cannot go to Huguang westward. Let's go downstream to join the Governor Ma. If Jiangxi is not protected, he will be besieged by the Ming army. Only by trying to protect us can we gain strength!"

In the past year, the Nanchang Shogunate and Changsha Shogunate have become much dirty. They went there to seek death by seeking death, so they naturally don’t look more reliable than Ma Guozhu.

"We are in chaos and everything is obedient to the military. We will do our best to cooperate."

In this way, Raozhou Prefecture was in chaos for a few days, and finally prepared and drove into Poyang Lake with everything they needed. However, the day after the fleet left, Li Benshen, Hu Quancai and others arrived late. Looking at the docks that were crowded in the past, like ghosts, especially the wreckage of those ships that were inconvenient to take away, Li Benshen couldn't help but blurt out a few sparks of lightning.

"Zhang Daocheng, a coward, your mother!" (To be continued.)
