The struggle of the reborn prince

After all, Hu Tuci was still a fool, Zhao Tun was not so kind, he rejected his request to return to Song Dynasty, and put Ye Sugui back and did not keep him as a hostage according to the usual practice. They were all bought.However, moving their tribes into the Song Dynasty cut off their chances of contacting and reuniting with other tribes. Even with the support of the Song Dynasty, it may be difficult for them to develop further.

The new site chosen by Zhao Tun for the Mughal tribe was near the boundary between Song and Jin Dynasties. This was said to be convenient for the Mughal tribe to return to the old place, but in fact it threw the entire "safety zone" to the Tatars.According to the current situation, the Jurchens obtained a strategic buffer zone, but the Song Dynasty changed the place for the Mughals, which made it easier for them to launch cross-border attacks on the Jin Kingdom. Even if Song and Jin reached a peace agreement, their behavior could not be restrained.

The Tatars were deeply influenced by the proximity of the nomadic land to the farming area, and accepted part of the ideas of the farming culture. As a result, they lost the "pure and simple" nature of the nomads. Like the Wangu people, they are known as the most "smart" people on the grassland.But they didn't learn much about good things, but they learned a lot about playing tricks and playing tricks, and they became advocating interests and changing their positions.And the reason why they attached to the Kingdom of Jin at the beginning was because the Mughals were too powerful, they couldn't beat them, and if they understood the principle that the enemy's enemy is a friend, they could get great benefits.

The real person also needs a force to fight against the Song Dynasty, so that the Tatar people can hit it off, they each get what they need, it can be said that it is a pure mutual use relationship, everyone knows this well, naturally they have their own ghosts, But he himself is not rich, and he is stingy about aid, wanting to do more with less money.So Jurchen's conspiracy is still a little bit worse than that of Zhao Tong.He spends money generously and does a good job on the surface.Even though he knew he was being used by Da Song, he was willing to die for him.

After the Mughal failed to move into the Song Dynasty.They are the largest tribe on the grassland, and they are now in the honeymoon period with the Kingdom of Jin. I believe that this winter will not pass. With the support of the Jurchens, the Tatars will be able to subdue the small tribes on the grassland and take over the Mughal tribe. Kill all the 'remnants' of the grassland and become the new overlord.With the nature of the Tatars, they will no longer be willing to submit to the Kingdom of Jin, and the conflict between the two sides will be inevitable.

At that time, Jin Guo not only had to consider dealing with the Mughals lurking around and staring at them, but also beware of allies who would turn their backs at any time.This will involve a lot of energy, and more troops must be deployed on the border to prevent changes.In the past, the west and south of the Kingdom of Jin bordered the Song Dynasty.In the past, the troops deployed by the Song Dynasty in the west were mainly used to guard against the nomadic Tatar tribes in Xixia and the desert. The Song and Jin Dynasties were separated by the Mughal and Tatar tribes. Therefore, the Jin Kingdom has always regarded the southern border as the center of defense.

With the great changes in the current situation of the Song Dynasty's Western Expedition, Gaochang Kingdom was destroyed, Xixia surrendered, the Naiman and Kelie tribes in the desert were expelled, and the Wanggu tribe was defeated. The Song Dynasty has pacified the western border.Now that the Mongolian tribes have moved into the Song and Jin border areas, the Jin Kingdom will face the threat of the Song Dynasty.And the Mughal Department also became a sharp knife that pierced his waist at some point, forcing him to move his defensive focus westward.

Although the eastern part of the Kingdom of Jin is separated by sea, Da Song can rely on his superiority in the water force to land in the coastal areas at any time.They can also attack them by land through the two bases of Koryo and Helandian, which makes them have to be careful.With the tense situation in the west, the Jin State will deploy its limited troops like peppercorns on the entire Song-Jin border, which will make it fall into fortification everywhere.The embarrassing situation where the line of defense is weak everywhere is just like the so-called loss of Dongli and harvest of Sangyu...

Zhao Tun treated Hutu Chai of the Mughal tribe so high-profilely.The spies of the Kingdom of Jin who were lurking in the Song Dynasty sent the news back to the country as soon as possible, Wu Shu heard it as if someone poured ice water on his head when he was in high spirits.The heart is very heavy.Over the years, the Song and Jin countries seemed to be calm on the surface. Generally, problems were resolved in the form of negotiations, and no large-scale armed conflict broke out.But both sides understand that the hatred between the two countries will eventually be resolved by a war. The Song Dynasty is actively preparing, and the Jin Kingdom is actually not idle.

In recent years, Wushu presided over the government and put his main energy on the construction of border defense.He knew very well that Song Dynasty had changed the situation of lack of horses after winning the Northwest Ranch, and cavalry had become its main force.And after they lost control of the Sixteen States of Yanyun, the southwestern border was also in a predicament where there was no danger to defend. As long as the Song army was willing to use the advantage of firearms to force a breakthrough at any time to prevent the horse from going north.

Since the Song Army has a powerful navy, the vast ocean is no longer an insurmountable moat.Since the navy of the Jin Dynasty was completely lost in the Liaodong Bay naval battle, it has been unable to reorganize a navy of the same size to fight against the Song navy, and only retained a small fleet to protect the inland river, so that the Song Dynasty navy can travel unimpeded along the coast of the Kingdom of Jin , He almost regarded the sea area of ​​the Kingdom of Jin as his own garden, and came here for a stroll if he had nothing to do.

Facing the border full of loopholes, Wushu, who advocates offense, knows that their army cannot defeat the Song army in field battles and counterattacks. Therefore, under the extremely tight financial situation, Wushu spent a large amount of money to mobilize Hundreds of thousands of soldiers and civilians built defense facilities in the southwest - Jiehao.

In view of the actual situation, the design of the boundary trenches built by the Kingdom of Jin is unique. It is different from the Great Wall of Qin and Han Dynasties, which was built on the large ridges across the mountains and guarded by the mountains.Instead, they are built on relatively gentle grasslands and on gentle slopes and flat ground at the foot of the mountain. Even when they need to pass through mountain ridges, they all pass through lower depressions.There are four fortifications in the structure, including outer moat, outer wall, inner wall, and inner moat, and the building materials are mostly earth or earth-rock mixture.Only some locations are compacted.

In the entire defense system, the boundary trenches use linear defense as the most advanced means of defense, while the military settlement defense system is located behind the boundary trench project, and a part of them is evenly arranged along the boundary trench line, forming individual defense points on the defense line The other part is arranged in a north-south depth, serving as the supply of manpower and material resources for front-line operations; the other part is used as a command system, located in the innermost part of the defense line, and connects the linear trench defense with the point-shaped settlement defense network through the information transmission project , making the boundary trench military defense project more complete and optimized.

The defensive engineering system is based on the Jinjie trench, which is composed of trenches, trench walls, horse faces on the walls, and female walls.The boundary trenches are built with soil, which is in the shape of a trench to prevent the horses from rushing over.Dig trenches and borrow soil to build walls on the inside. The depth of the trench and the height of the wall are at least more than one foot, and the height can reach more than half a foot.There are horse faces built on the wall every twenty feet, which are higher than the wall and protrude outside the wall, so that the guards can condescend to shoot arrows and strengthen their defense.

According to the strategic importance of the area, it is equipped with different types of defense facilities such as single trench and single wall, single trench and double wall, and double trench and double wall.The shape of the double moat and double wall consists of four parts: the main wall, the inner moat, the auxiliary wall, and the outer moat from the inside to the outside. The minimum total width is ten feet, and the maximum is twenty feet.The width of each trench should not be too large or too small, too small can not effectively prevent the horses from crossing; too large will make the horses trapped in the trench jump out of the trench easily.Build an earthen fortress about seven or eight miles along the boundary trench, which can accommodate four to five hundred people, and is the place where troops are stationed.

The information transmission project on the Jinjiehao line is an important part of the Jinjiehao defense engineering system, which is completed by the beacon tunnel and the sudden shop.The function of the beacon tunnel building is to call the police in time, to transmit military information by lighting fireworks, and to inform the superiors of the news on the front line.Corresponding to the beacon fire, that is to say, the beacon towers are arranged at intervals, and they can respond to each other in case of situations.The function of the sudden shop is to exchange military information, ensure the safety of military material transportation, and provide personnel who deliver official documents or officials who come and go to live temporarily, change horses, etc.Its scale is similar to that of a military castle, with city defense facilities.

On the eastern coast, Wushu built a number of fortresses in key locations where ships could berthed, and erected wooden fences along the coast, then dug trenches and rammed walls to resist the landing of the Song army.Coastal prefectures and counties set up patrol navies, set up lookout posts, and deployed troops on coastal islands to guard and guard.In order to prevent the Song navy from going upstream along the inland river from Haikou and going deep into the inland, he also pulled up iron chains at Jiangkou and prepared a lot of old ships.

But the blueprint is beautiful, but the reality is skinny. Although Wushu has tried its best to promote the construction of the boundary trench, it has only completed the infrastructure construction in key areas over the years. Many places still need to be improved, and more places just stay on the blueprint , not implemented.Now that the Mughal tribes are on the border between Song and Jin, there will inevitably be friction, which will lead to conflicts. If it is not handled properly, the Song people may be involved, and a war between the two countries will break out.

Wushu used the Tatars to exterminate the Mughals originally to get rid of the confidant’s troubles in the west, and then used the Tatars to control the grassland for a long time and guard their own borders to reduce the military pressure of the Song Dynasty on the Kingdom of Jin. It is a good thing to kill two birds with one stone. .However, after the Mughal tribe was disabled, their strength was greatly reduced. In his opinion, no one will help a waste that has lost its use value. After that, the Tatars can eat it to nothing. What is even more pleasing is that Zhao Er suffered from being dumb and unable to tell.

Wu Shu didn't expect Zhao Er to be so 'good' at heart, beyond everyone's expectations, he took in the Mengwu tribe regardless of previous suspicions, and promised to help them take revenge.In this way, it not only demonstrates the "noble morality" of the Song Dynasty to repay grievances with virtue, but also makes a game of deadly chess work, without moving a single soldier, easily turning passivity into initiative, and at the same time throwing a powder keg that does not know when it will explode. They overthrew the Kingdom of Jin, forcing them to adjust their strategic layout and strengthen their defenses in the west, making a hard-won victory come to naught...
