Taoqiu's sailors were dispatched again, this time, it no longer needed to stare at the big rivers in the Song Kingdom, nor did it need to stare at Huaishui and Surabaya, Dai Yan brought almost half of the sailor's strength directly to Suishui and launched an attack on the Chu army on the opposite bank!

Located on the other side of the city, the industrial zone of Sangyi is a city surrounded by rivers on three sides. Previously, the Chu army was able to quickly conquer it through the freezing of the water surface in winter, but now the Song State wants to capture it, but it is not so easy.

Even though Dai Yan had a powerful fleet of sailors in his hands, after the Chu army completely closed the passage near the shore of Suishui, and even built a wall on the edge of Suishui, the Taoqiu Sailor could no longer directly attack the interior of the industrial zone! Therefore, Dai Yan chose a decision that made Taoqiu merchants extremely sad - to destroy all the industrial facilities on the shore of Suishui!

You know, these were originally the properties invested by the Taoqiuyi Mansion and the merchants, and those merchants originally thought that they could take back these wealth from the Chu army! However, Dai Yan didn't feel any pain, even if there was originally a part of him in these properties! In his opinion, now that these properties have fallen into the hands of the Chu army, if they continue to produce iron products, they will slowly increase the strength of the Chu army!

Instead of twisting and pinching like this, it is better to destroy it directly! If you go to war, don't be afraid of losing these pots and jars, and when the war is over in the future, you can talk about construction and then do construction!

The iron-making blast furnace, coal washing facilities, coke ovens, etc., erected high, Dai Yan directly instructed the Taoqiu sailors to destroy them with ballistas! When the Chu army built the city wall, it originally did not consider that the Song army would be so ruthless and directly destroy these facilities without hesitation, so it did not protect these huge facilities!

The entire Xiangyi Industrial Zone, after losing the most important facilities, also lost its coking capacity and iron-making capacity. In this way, such an extremely important industrial area will not have much effect on the Chu State!

This made it extremely embarrassing for the Zhao clan, who sent 200,000 troops to the shore of Suishui to protect the Xiangyi Industrial Zone!

In this way, the Chu army will plan to retreat. However, Chu Jun has been staying in the Xiangyi Industrial Zone for more than half a year, and they have basically understood the operation logic of the entire industrial zone, and they also know the important role of Xiangyi coal and iron mines!

Zhao Hua, who had full command of the Chu army's troops, immediately made a decision to move all the workers in the Xiangyi Industrial Zone to Yangling, and then establish a new industrial zone in Yangling, while the Chu army only kept the Xiangyi Coal Mine and Xiangyi Iron Mine!

In the process of the initial withdrawal of the Chu army, the Song army had already landed on the west and south banks of Suishui by virtue of the advantage of controlling Suishui. Dai Yan, who held an army of more than 200,000 in his hands, did not rashly launch an attack!

He was waiting, waiting for the Chu army to retreat to reveal a flaw!

However, this idea of his is not easy to achieve. Although Zhao Hua had suffered a lot of losses at the hands of the Taoqiu army, this person could become a famous general of the Chu State, and he did have extraordinary abilities. In the process of the gradual withdrawal of the Chu army, Dai Yan couldn't find any targets to attack at all!

This point makes Dai Yan ashamed of himself! A general who can lead an army to attack is indeed remarkable; But the generals who were able to lead the army to retreat safely were even more remarkable! When an army retreats, its faith will be shaken, and it will also worry about the opponent's sudden attack, in which case, it is easy to make a flaw, thus giving the attacker a chance!

In history, Fu Jian, who held an army of millions, won a hundred battles in his life and created a great foundation, but because he did not do a good job in a retreat during the Battle of Weishui, he lost everything, even his life! The retreat led to the collapse of the army, which is a mistake that even a king like Fu Jian, who has experienced a hundred battles and has a high prestige, can handle it without leaking when leading the army, which shows Zhao's ability!

When all the workers in the Xiangyi Industrial Zone were evacuated, the Chu army that followed closely behind also began to evacuate.

When the Chu army retreated to the Xiangyi coal and iron mines, they continued to stay. Subsequently, Zhaohua sent an envoy to Dai Yan's side to negotiate peace with the Song State.

Now the only requirement of the Chu State is to get the coal and iron ore of Xiangyi. For this reason, Dai Yan ascended to the throne of the Song State in the future, and the Chu State could recognize it. Moreover, the state of Chu could allow the state of Song to continue farming on the banks of Suishui and promise not to harass it again in the future!

For the state of Chu, it is the first time that such a concession has been made to a "weak country". However, Dai Yan did not let everyone put it in the parliament for discussion, so he directly refused!

Today's Song Kingdom itself is a place with narrow terrain. In later generations, he also knew a little bit of geographical knowledge, and knew that in the place where the Song Kingdom is located today, there are basically no more coal mines and iron mines. If Taoqiu's industry loses such an important source of raw materials, how will it develop in the future?

You can't continue to rely on imports to solve this problem, right?

In fact, there is already a problem with the source of raw materials for Taoqiu. In the past, when the war was waged, Taoqiu could also bring back enough coal and iron from Zhao to meet Taoqiu's needs. However, when the Wei State had become an enemy, they were prompted by the Chu State and began to hinder the transportation of coal and iron from the Zhao State to Taoqiu!

Although Taoqiu has the previous storage, and through other scattered ways to obtain some coal and iron raw materials, but without the continuous supply of raw materials, Taoqiu's industrial base has faced a great crisis!

Dai Yan finally understood why Britain, as the leader of global trade and the initiator of the industrial revolution, wanted to build a navy that could win the second and third powers at the same time. Because otherwise, they will not be able to control the flow of resources around the world, and thus ensure that industrialization proceeds!

Later generations of US imperialism continued this line of thinking of the United Kingdom, dominating the seas with aircraft carriers occupying 80% of the world's tonnage, controlling the world's transportation arteries, and also continuing the same theory as the United Kingdom!

In the case that the current Song State cannot remain strong enough and obtain raw materials from all over the country, regaining the coal and iron mines in Xiangyi is not only a matter of life and death for Taoqiu Industry, but also a big issue related to Dai Yan's position and even the future development of the Song Kingdom!

Under such circumstances, how could Dai Yan accept the proposal and decision put forward by Zhao Hua!

In fact, in today's era, the land area of Chu has exceeded at least one million square kilometers, even if there is a general lack of coal mines in the south, as long as you look carefully, you can still find enough raw materials! However, the state of Chu didn't bother to do such a thing at all, in their opinion, since there was something ready-made and placed in front of their eyes, why not just take it away?

In this way, the war between the Song State and the Chu State is a pure conflict of interests, which is a kind of dead knot that cannot be untied, and the war will never end unless one of the two sides wins!

When Dai Yan rejected Zhaohua's suggestion, the guard of the Chu army deepened, and the 200,000 Chu army entered a state of imminent battle!

Dai Yan also put such an army on the other side of Suishui. Of course, considering the danger of camping on the back of the water, and the fact that the powerful sailors could support at any time, Dai Yan only sent more than 70,000 troops to camp on the front line, and the follow-up troops stayed on the opposite bank, ready to set off at any time!

Although the number of troops on the front line was smaller than that of their opponents, the army of Tauqiu was now beginning to grow stronger. And the army on the front line has a Chu army at this time, an army that is completely impossible to fight against - cavalry!

After the unification of the Song Kingdom, Dai Yan almost demolished the chariots and soldiers of the Song Kingdom, and then scavenged nearly 10,000 horses from the entire country. With so many horses, and thanks to the foundation laid by Taoqiu's original horse racing and polo matches, plus the riders composed of the outstanding riders gathered by Dai Yan in the Song Kingdom, the Taoqiu cavalry strength, which had been reduced to 2,000 people, began to swell again, and the number of cavalry quickly reached 5,000!

The individual combat effectiveness of this cavalry, except for the original veterans, is not strong, even if Dai Yan has been training continuously in the past few months of war preparation, the situation has not improved much. Dai Yan thus recognized that cavalry is not a kind of military that can be manufactured in batches, it is just like the air force of modern countries in later generations, it needs to have enough professional personnel to operate in order to have an expanded base!

However, even if it is a cavalry with poor combat effectiveness, under the leadership of elite cavalry as the backbone, its combat effectiveness is far from being comparable to that of a purely infantry team like the Chu army. The newly formed cavalry of the Song State, under the leadership of Le Yi, began a long-term harassment of the logistics of the Chu army!

To be honest, relying on the advantage of speed to disrupt the opponent's logistics is one of the most important uses of cavalry. It was by virtue of this almost scoundrel trick that the northern nomads repeatedly won great victories in wars with successive dynasties, and unless the dynasties could have the same cavalry to ride on, there was basically no very good way to defend themselves!

Such a scoundrel tactic, as soon as it is used, even if it is an old battle, and even the Zhao Slip that destroyed the Yue Kingdom, I feel a headache!

The cavalry faced this kind of opponent, with only one volley from a distance, and then through a round of impact, the militia responsible for defending the grain route immediately collapsed, and then these cavalry would burn all the grain!

Faced with the tricky cavalry, Dai Yan began to come up with various ways to deal with these cavalry. In order to ensure that the grain could be transported back, he gradually dispatched more elite clan soldiers to protect the grain routes. Soon, the cavalry of the Song Kingdom, which was attacking logistics, also began to change their routines!

The cavalry, which was originally divided into a team of more than 100 people to be responsible for sweeping the net in a large area and harassing them, was assembled together in a very short period of time. When a thousand-person cavalry attacked, even if it was the Le clan's soldiers, if they did not have an absolute advantage in numbers, it was very easy to collapse!

And once it collapses in front of the cavalry, there is almost no way to live! The cavalry's pursuit ability is really terrifying, plus the transportation lines of the Chu army's logistics are mostly on the plains, and even if there are mountain roads, they are relatively low hills, and there is nowhere to hide in front of the cavalry!

In this way, Le Yi relied on the advantages of the terrain to give full play to the advantages of the entire cavalry team!

In this way, Zhao Slip knew that the infantry alone could not compete with the cavalry of the Song Kingdom. He also drew all the chariot soldiers from the Chu army and used them to protect the grain route. However, in the previous Song Civil War, Dai Yan was able to defeat Pengcheng Lingzizhang's chariot soldiers with cavalry alone, and the cavalry led by Le Yi himself, where could he not do this?

The cavalry of the Chu army was also annihilated by Le Yi as half of what Dai Yan had done before, with the advantage of speed.

Subsequently, Zhao Hua came up with a solution that was not a solution: imitate the opponent to create the same cavalry, and use horseback to fight against the cavalry of the Song Kingdom!

This was originally an excellent way of thinking, but unfortunately, the Chu army now has no cavalry thinking and routines that no one understands. To put it mildly, with his excellent war experience and his innate war talent, Le Yi has become one of the generals who know the most about cavalry in the world!

He only set up a little bureau, and he forced the soldiers of the Chu army, who had just mounted on their horses, to engage in a field battle with the real cavalry that had been trained for a long time! In this battle, the cavalry of the Song army, as the "teacher", was unceremonious to the "students", and directly crushed the cavalry of the Chu army in an indestructible way, and captured all the horses!

The strength of the cavalry of the Song army, in the case of getting such a large number of horses, the strength is expanding more and more!

In the end, Zhaohua had to send the most elite infantry, and even Chu Wushu, to deal with the cavalry of the Song army in order to maintain the stability of the grain route!

And he finally discovered how to use infantry to deal with cavalry attacks! That is, once you see the opponent's cavalry and are about to attack, immediately let all the infantry line up as fast as possible, only in front of the neat infantry array, the cavalry can not find the direction of the attack, and then have to give up the attack!

And using such elite infantry to deal with the cavalry of the Song State can only force the opponent back, and it is extremely frustrating to know the results of this battle!
