Before the war, Wang Ju and Zhang Feng made repeated deductions in their minds.

If they want to defeat the Liao army, as long as the Liao team comes to Xiazhou carelessly, they will be doomed to be defeated, not to mention the division of troops from Youzhou, Hongzhou and Yanzhou.

But they were heartbroken to beat them.

Because this section heads north is the famous Nanhetao, which is thousands of miles in size and is almost equivalent to most of Hedong Road. Therefore, Li Jiqian was defeated by the Song army and drilled into the Hetao, and then the Song army was stunned.

The Liao army was not Li Jiqian, but the nomadic peoples such as Nanhetao were more loyal to the Western Xia. The Liao Kingdom came to support the Western Xia, so they had a high likelihood of the Liao army. Including this vocation, the Liao Kingdom invited many herders from the Hetao area as guides. If you talk about it in depth, it was a contradiction between agricultural civilization and nomadic civilization. The Song Dynasty was a farming civilization country, how could it be expected that the nomadic people would be very loyal to the Song Dynasty? Unless the Song army was strong enough to suppress any opponent, they would be honest under the majesty of the Song Dynasty.

In this context, Liao Kingdom will suffer heavy losses, but what group of people will suffer?

A civil servant!

But these civil servants were organized from behind the mountain, and they were basically Han people. Let them go, there is no deterrence. Killing cannot be killed. Regardless of the national position, all Han people behind the mountain will completely turn to the Liao Kingdom by killing.

The main force of the Liao Kingdom, led by local herders, was a cavalry and an extremely wide place. It would quickly enter Nanhetao and then retreat.

But the problem is not over yet. In fact, starting from the Liao Dynasty's actual troops to the northwest, the two countries' shamelessness is equivalent to being captured and the war is over. The Song Dynasty cannot arrange hundreds of thousands of troops here, such as Tiemen Pass, at most, the officers and soldiers stationed in a battalion, which is, Hetao, in addition to organizing some border troops to save financial resources, the regular soldiers are only a few generals. The best example is that the twelve generals and soldiers of Hedong, and the eight generals and soldiers took turns to garrison at Fulin Road, which means they are divided into two shifts, each shift of four generals to defend against Linzhou and Fengzhou. The remaining four generals are divided into two generals to defend against Daizhou Volcanic Army.

This is the normal defensive force, but the problem is that in this war, the nomadic peoples in Nanhetao were twisted together with the Liao Kingdom, and if they were led by them, there would be loopholes everywhere. At the very least, the Nanhe River Hetao would be lost, and at the worst, the entire northwest rule would be threatened. Therefore, this battle would have to fight the Liao Kingdom, which would make them immediately silent when they mentioned the northwest.

This is why this cage tactic is created.

Inland river boats want to sail safely, not just rivers, big rivers, big boats, small rivers, small rivers, small rivers.

The factor that endangers the safety of ships is the large difference in river suspension, such as above Qingtong Gorge and to Yingli Zhongwei, this section of river surface is wider than the river surface below. However, because the water level drop of Qingtong Gorge is large, it is not conducive to navigation.

But it depends on how to use it. It is precisely because of this water level gap that it is built with it, such as the Hanyuan Canal, Tanglai Canal, Hanbo Canal, and Seventh-level Canal. During the Yongzheng period, it used it to build the Huinong Canal. After liberation, it built the Donggan Canal and a Qingtong Gorge, which created 90% of the water conservancy irrigation project in Ningxia.

Secondly, there should be no reefs. The famous one is the Three Gorges. The water level drop is large, resulting in rapid water flow and many reefs, so there are frequent accidents.

The water level changes cannot be too large. For example, if Lanzhou is not afraid of danger, the entire upstream navigation will not reach Qingtongxia, but will always reach Lanzhou. However, the water level of the Yellow River in Lanzhou has changed greatly, with many stones at the bottom of the river, and there are some steep sections left, so it is not conducive to larger ships and the navigation risks are high.

This time, Wang Ju attacked Xia and deliberately brought many craftsmen from some docks in the Wei River Basin. He trained some naval troops in Guanzhong the year before yesterday, but he never thought about building ships in Lanzhou to save transportation costs.

The river cannot suddenly become narrower. The shipping mentioned by Wang Ju is Lingzhou in the upper reaches and the lower reaches are Hekou Ferry. When crossing the river from the estuary, the Yellow River belongs to the middle reaches. In fact, this section of the Yellow River has many gorges but not dangerous. If you turn around from the Hukou Waterfall, the channel can extend to the Yumenkou of Longmen.

But the problem is that from the mouth of the river, the river suddenly contracted and the water flow became turbulent. With the technology of the Song Dynasty, navigation was still very dangerous, so Wang Ju never considered it.

Finally, there are many rivers and berths. Ships sail by the inertia of the water flow. Unlike on land, we brake suddenly. When the boatman sees the bay road, he must make predictions in advance. At the same time, the bay road will produce backflow, causing many uncertainties in the hydrological characteristics. The most famous one is the main pillar of Sanmenxia. According to the inertia of the water flow, the ship that exits Sanmen just hits the main pillar. I use the rudder and I use the rudder to rudder, but accidents often still cause accidents.

So what are the characteristics of this section of Yellow River? It is wide, with gentle water flow and many bays, so it is called the river curve. Especially the horizontal line above the few characters is not straight. The section of the river line of Jishijun is called Jiuqu, but that horizontal line has at least ninety-nine curves!

However, there are many curves, but because the river surface is wide and the water flow is gentle, the navigation risk is still very small. However, it causes a phenomenon that frequently diverts the route.

The Yellow River leaves the Helan Mountains, and there are deserts and Gobi on both sides. When the wind blows, the sand flies to the Yellow River together. However, because the water flows smoothly, the river sand immediately settles. For example, the river in the southern section has a bay mouth, which produces a return flow. The river water does not go downstream, but rushes into the middle of the river. Therefore, the river sand will accumulate rapidly in this area, but the river water must flow downward, so the river water becomes quick and plunders the mud and sand on the north bank, thereby causing a diversion.

The most famous one is in the 24th year of Jiaqing in the Qing Dynasty. The Baotou Nanhe section moved one and a half way south. In the second year of Guangxu, the Baotou Nanhe section moved south on a large scale. Now there are two very good ferries, Heshuo Dutto Hekou Town, and Maodai Du Salazzi. Because of the prosperity of the ferry, it created two prosperous towns. However, after the Yellow River moved south, it lost the effect of the ferry bonus. Saraz was a little better and became part of the Tumote Right Banner County Government. As for Hekou Town, there are so many Hekou Town in the country that it cannot find this Hekou Town because it has become Hekou Village! Then Baotou Nanhaizi Dui began to prosper.

However, these two diverting times are considered to be the larger scale of this section of the Yellow River. Although the remaining diverting is frequent, the scale is often less than a few dozen meters, and it is also a rare place to travel, so historical books do not record it. However, it is precisely this kind of terrain that creates more and more bay roads. After a long time, the river channel has changed a lot. For example, in Fengzhou of the Tang Dynasty, the Uga River north of Wuyuan was only the sub-river of the Yellow River, but now it is the main river of the Yellow River. Later, the main river of the Yellow River is now just a small river bay.

Then there is the middle reaches of the Yellow River, which flows down from the mouth of the river. There are many mountains on both sides and the river flows fast. However, it is bound by the mountains on both sides, and the river sand is not easy to settle, so the river channel has always been very stable.

Then go to the crossing of the three armies.

A small river builds a bridge directly, and opens a road to a mountain. That is, the army in front cuts off shrubs and thorns, allowing the army behind to march quickly. Building a bridge when encountering water refers to such a bridge. It is impossible to build a bridge over the Yellow River and the Yangtze River.

When you arrive at the ferry army in the river, if you are not in a hurry, you can use a ferry boat to ferry slowly.

If it is very urgent, the Xixia people used Huntuo to cross the river. There is another way to build a floating bridge. The most famous one is the Song Dynasty's migrant to the southern Tang Dynasty. The floating bridge on the Yangtze River was connected with iron chains, laying wooden boards on it, and the army crossed it!

But if the army is large, then it is extremely picky about this ferry.

First of all, the water flow at the ferry must be smooth to ensure the safety of the three armies. Secondly, the ferry must be large to accommodate many ferries ferry at the same time. Otherwise, a boat will ferry slowly. Xiang'outra led more than 100,000 soldiers and civilians here this time. How long will it take to complete the ferry?

If it were to build a floating bridge, it would be even more picky, just like the floating bridge on the Yangtze River in the Song Dynasty. Fan Ruoshui drove a small boat to pretend to fish on the Yangtze River. After choosing, he only chose Caishiji. He then used a silk rope to measure the width of the river surface. The Song Dynasty built the floating bridge based on the information he provided.

These may sound complicated, but they are immediately related to the following cage combat plan

Otra is still in the valley for the time being, but Yanzhou City is so difficult that he feels something is wrong.

So he first focused his eyes on the southern test of the seventh-level canal. Where did the Song army set up a huge dock, not only the imperial officers and craftsmen, but also tens of thousands of Western Xia prisoners of war and the people.

Now we have started to go from chaos to control. We can no longer use the bloody means of the past. However, after repeated urging the Western Xia, the people cannot even solve the problem of food and clothing, but we cannot let them starve to death. It is not that they are starved to death. Once they are so hungry that they are desperate, they will take the initiative to rebel. Therefore, Wang Ju adopted labor-for-relief measures, including those prisoners of war who were constructing in Hexi. Everyone works. The Song Dynasty brought food, grass and cloth from the rear to distribute materials for labor.

There were many people, but the Song army immediately needed a lot of ships.

If a cavalry was sent to attack the dock, it would have a huge shock. However, soon the scout sent a message that the huge army was still retained in Yu Yaode City and other places in the Song Dynasty.

If the number of troops is not effective, the number of troops is too high. First of all, the difficulty of the vast sea terrain is a headache. Even if all cavalry are sent, Otra is worried about ending like Lingzhouchuan. Once the cavalry is hit by a devastating blow, this army will usher in a tragic fate.

Then he stared at the west side of the ancient Great Wall, but the problem was that this ancient Great Wall was coming out. How to cross the Yellow River? The Song army could not watch the Liao army build the ships. Besides, he did not bring many craftsmen who were good at building ships this time.

Then he stared at Hengshan again. Otra knew how difficult it was to deal with Hengshan. However, Hengshan has not had many troops now, but in this way, it would be equivalent to formally declaring war on the Song Dynasty, and the consequences were unpredictable.

Forced by helplessness, he sent a large number of cavalry to Hengshan. The Song army at the forts in Hengshan ignored it. We dared not leave the fort, but we had no way to capture our forts. After so many years, Song Xia has leaned against Hengshan and launched many tug-of-wars and defensive battles.

Then Otla received news that the Song army suddenly sent troops to Jinsu City.

Otla is a little confused, we have not attacked your Song Dynasty. Why should your Song Dynasty attack our Liao Kingdom?

But the problem is.

If Otla had brought these 100,000 soldiers and civilians around Nanhetao, the Song army would have no way to deal with it.

But how to solve this stroll, what to eat, drink, wear and tea?

Therefore, the Liao army had to go back, and if they went back, they had to cross the Yellow River. Don’t think about the river section west of Muna Mountain. They were all occupied by the Song Dynasty and began to build forts and garrison troops. Moreover, there were a large number of soldiers patrolling the Yellow River on boats, how to allow the Liao army to cross the river.

Then the Liao army wanted to go back, and there were only two places, one was Baotou. It is not called Baotou now, but Yunneizhou, also called Jiashan or Xishan area.

That section of the Yellow River was wide and flat, with many ferries suitable for crossing the river. However, the problem was that where to cross the river, you had to cross the entire Nanhetao and cross more deserts. Logistics supply immediately became a big problem.

In fact, even if they chose this way, they would not be able to successfully go back. Liao Xingzong defeated Xia, but although they were defeated, the people in Xixia were living in poverty. Li Yuanhao did not take the opportunity to take back the Jin Su army and Heqing army, and then went north. Aboushan above Muna Mountain was the Heishan area, which was the area of ​​Sujiangcheng in the Tang Dynasty. Yelu Abaoji defeated the Dangxiang tribes, occupied this area, and established the Tiande Army. Under this pressure, Xixia had to build some forts in Muna Mountain and four castles in Henan to guard the Yellow River.

I am not afraid of the Liao army coming through the desert, but I am afraid of the Liao army coming from the Yellow River.

Now all these forts have been taken over by the Song army, and Wang Ju asked a large number of soldiers to take logistics to the owner of the ship. There were Song army attacks on the land and ships patrolling the waterway.

At least it took a while for the Liao army to build ships and cross the rivers or build floating bridges. Moreover, this area is mainly composed of Ganyuan, and the trees are short and drought-tolerant trees. It is very difficult to find wood suitable for shipbuilding. Even if it is built well, it will still face the suppression of the Song Dynasty naval army.

So there is only the second road, which is the ferry crossing the Yellow River by the Liao army, and the Labawan Ferry crossing the Junzijin Ferry east of the Jinsu army. The river surface in this area is relatively straight and wide, with gentle water flow. It is also the best ferry crossing at the mouth of the Yellow River.

There are other small ferries, but this is the retreat ferry of more than 100,000 troops. Are those small ferries suitable?

However, now that all these two armies and one state have been taken down by the Song army, can Otra not be anxious?

He didn't care whether Xingzhou City was taken down by the Song army, and immediately led his troops to retreat.

Poor Shidao and Liu Changzuo were afraid that he would be crazy, so they placed some troops in Hengshan. However, without a single arrow, Otra retreated.

But what made him relieved was that when the people of these states heard the Liao army retreated, many soldiers and civilians spontaneously requested to follow the Liao army to the Liao Kingdom. The Liao Kingdom has no population crisis yet. On the contrary, after the Liaodong rebellion, many Dings and Zhuang died.

Moreover, there were many nobles among these people. Although they were not as good as before, they still had a lot of wealth in their hands. So they gathered all the way, and in the end, the number of soldiers and civilians in this marches reached 200,000.

Otla withdrew, and almost none of the people left behind in the three prefectures were loyal to the Western Xia. Qingzhou Yanzhou sent troops to easily recover the three prefectures, and then quickly built the city walls and built fortresses, including Baichi City, Tiemen Pass, Sanchakou, Zuocunze, Naiwangjing, and Wuyancheng. However, some important areas in the northern part of Xiazhou, such as Huangyangping, Qiliping, Anqingze, Dashadui, Wangting Town, and Dejing Town, did not care about them, and they were not important. Once further repaired and connected, they could become the best northern gates of Xiazhou. Moreover, this area was also the most important agricultural and animal husbandry area in Xixia. These prefectures must be rebuilt to protect the development of this area. However, it is too late to be too late to build, and it is better not to worry about them.

When Otla arrived north, he had already received news of the loss of Xingzhou when he arrived at Huangyangping. However, because the Yellow River patrol was strict, the scout did not find out the details. However, he still believed that the main force of the Song army was behind him, either going down the waterway, not to mention how much troops it could carry with a ship, or carrying a lot of troops. The river surface of this section was smooth, and there was almost no gap in traversing and countercurrents. Moreover, there were many bends, which was equivalent to extending shipping, and then going ashore and taking a distance. Therefore, even if the Song army wanted to fight with the Liao army in the Jin Su army, it was too late. Or cross the Yellow River, not afraid of hard work, and follow the road of the ancient Great Wall to Yanzhou, and then to Hongzhou, Yinzhou, Linzhou, Fuzhou, and entering the Liao territory, it was too late!

Therefore, as more and more people joined, his march became slower and slower, but because of this illusion, Otra was not in a hurry at all. On the contrary, these people would have many uses in the future, including counterattack. This is the territory of the Western Xia, why not counterattack? With these people, the Liao Kingdom would have the power of time, place, and people.

Moreover, because these people left their homes and brought out all the valuable materials, food, grass and livestock in their homes, the logistics of this line was very sufficient. And because many tribes in Hetao joined one after another, they provided many livestock water bags, brought enough water, and there was no shortage of water.

His troops set out towards the Jin Su army, and many "civilians" came from the Jin Su army to carry out construction so that more forts and forts could be built before the Liao army arrived. At the same time, they persuaded the people to harvest the unripe beans and millet and hand them over to the forts and forts and forts and for green feed. According to the weight they sent, relevant materials would be distributed in the future. This is nearby, and those far away from the Song Dynasty would be burned directly with fire, and then let the people go south and go to Linzhou to eat.

The main reason is that there are two advantages here. This area belongs to the Shengzhou area of ​​the Tang Dynasty. During the Later Liang Dynasty, the Liao Kingdom sent troops to capture all the people of Shengzhou to the Liao Kingdom. Later, they occupied the place, but the people who migrated were Han people from the Shanhou Prefectures. They did not expect these Han people to have much favorable feelings for the Song Dynasty, but they would not be too repulsive. At the same time, the main place is garrison, with not many people, and there are only 4,000 households in total, which is easy to resettle and migrate.

At the same time, the battalion leaders personally came forward and promised them the various benefits given by the Song Dynasty in the future to make up for their losses, but they still did not migrate, and used tough measures to forcibly burn their crops and houses.

When the Ortra army arrived at the Jinsu army, all the people in the two armies and states were migrated and the crops were also burned clean, which means that the Song Dynasty was about to implement the tactic of firm walls and clear fields.

This is also a common tactic, which has not yet aroused the alertness of Otra. Therefore, when he arrived at the Jin Su army, he did three things.

The first thing is to send an envoy to question Zhang Shouyou.

You Song people are so brave that they dare to invade our dynasty publicly.

Don’t you know that our Liao Kingdom is a tiger!

Zhang Shouyou also replied that since Li Jiqian, Xixia has been a group of scoundrels who are untrustworthy and traitors. Needless to say, there is too much evidence, such as Li Jiqian surrendered if he couldn't win. After settled down, he continued to rebel, which made the Song Dynasty watch him grow helplessly. After Li Jiqian's death, Li Deming was a little better, and Li Yuanhao came again, and then he was worse than the other generation.

Last year, after repeated mediation by your country, our dynasty agreed to peace, but the Liang thieves sent a large number of scouts to sneak into our country's border, spreading rumors and prophecies, and alienating our country's monarch and ministers. Therefore, our dynasty then attacked the Western Xia. Moreover, these scouts and evidence were sent to the border one after another, handed over to your country to explain to you.

But your country disregards morality and disregards the right and wrong, and first sent 30,000 cavalry to attack our country's supply. You led more than 100,000 troops into the northwest, first fighting Qiliping, then fighting Xiazhou City, and then attacking Yanzhou City, resulting in countless casualties in our country. Your country is unkind first, so don't blame our country for being unrighteous!

You have been doing the first day of the Chinese New Year, don’t blame us for doing the fifteenth day now!

Therefore, Hantla began to mobilize troops and launch an attack on some fortresses.

Then the elite cavalry were sent to Junzijin Ferry. Because the scouts had discovered that in order to stop them from crossing the river or prevent reinforcements from reaching, the Song Dynasty blew up the mountains and retrieve stones. The river beaches on both sides of the ferry were covered with stones, so that the ships could not cross.

This problem is not too big, because Otra has too many subordinates or people in his hands, so he first occupied the important places around the ferry and controlled the ferry. Then the army arrived, moved stones to build ships, or forced the ferry to build a floating bridge with a small boat. However, this was not for retreat, but for the purpose of ensuring the retreat, and then launched a counterattack against the Song army.

In addition, the Xijing left behind in the East, the three capitals of Liao were established in the prime minister's office, divided into the left and right prime ministers or the left and right seal government affairs. The following are the left and right officials or the co-magistrates of each capital. Because the Liao emperors ran everywhere, each capital had palaces or imperial palaces, and there were also introspective departments, and at the same time, there were various ministries, such as the Ministry of Revenue, the Du Branch, the Sansi, the Salt and Iron, the Cyberspace Administration, the Transportation Department, the General Administration Office, the Duyu Housing Office, the Police Inspection Office, the Disposal Department, the Five Beijings and Beijing Schools, and there were also the Beijing government office. The Imperial City Department, Tokyo also had Fengshang Office, Grand Governor's Office, Pacification Envoy Office, and Western Beijing had Wensi Office. The Inquiry Office, Patrol Office, Danei Deployment Office, Nanjing had Xuanhui Office, and the Disposal Envoy Office, each army commanded the Military Envoy Office, Liyuan Office, and the Liao Dynasty's north-south official system made the official system several times more complicated than the Song Dynasty. After hearing this, Yeluna also sent a group of troops to Junzijin and began to move the Jishi, preparing to take over the Ortra.

This is also because Otla was not nervous. If he was in a mood, he was just very angry and worked hard to expedition, and the Song Dynasty successfully destroyed the Western Xia.

Nearly 30,000 troops rushed towards Junzijin, and there were thousands of Xixia soldiers here.

Not too far, three hundred and ten miles away, all the Liao Kingdom were cavalry. Although they brought some supplies, they did not hinder much speed. If there was no accident, they could quickly reach the ferry in one and a half days and occupy the important land.

On the evening of the first day, the three armies rested in a valley. And Otra learned more of Wang Ju's tactics through the Xixia people and repeatedly told them to be careful. Therefore, although they set up camp here, the Liao army sent many soldiers to patrol and guard.

Whether it is useful or not, it is safe that night. And it may be that the Song Dynasty has few troops now. The poor military force only ensures the safety of each city and the fortress. Therefore, no Song soldier has come to harass him along the way.
To be continued...
