In the Song Dynasty, there was no law or order.

"Bang!"

As a warning shell fell into the Yu River, a huge splash of water burst out, and the chaos on the battlefield stagnated.

Then the remaining Liao army scattered to both sides like birds and beasts, and the Jurchens in the distance began to chase.

The crowd came and went in a hurry, as if it was a farce.

The Song army on the border breathed a sigh of relief.

The Liao-Song border in the northeast region is bounded by rivers such as the Daling River and the Yu River, which is almost in the area from Lingyuan City to Chaoyang City in later generations.

The border line is more than 200 to 300 miles from west to east. Although the combat effectiveness of the northern imperial army is strong, such a long border line cannot be defended at all.

If a large number of Liao and Jin defeated soldiers crossed the border and killed wantonly, and they did not arrive in time, they would suffer.

Now that the enemy has not crossed the Yu River, it is already the best result.

At this moment, the north bank is still in chaos. In addition to the Liao army soldiers, there are many Khitan nobles in Dading Prefecture who are also fleeing.

Many of them chose to flee to the Song Dynasty border on the south bank. In addition to rivers, there are many mountains and rivers that can be crossed. The Song army is simply unable to guard such a long border.

Therefore, a large number of Khitan nobles and defeated soldiers fled into the border of the Song Dynasty, causing considerable chaos.

Fortunately, those Khitan nobles and defeated soldiers were trying to escape, not to die. They also knew what would happen if they made trouble or even killed people in the Song Dynasty.

So when the villagers found them and immediately reported to the nearby government, they all waited for the Song people to come.

Compared with the Jurchens who killed them as soon as they saw them, the Song people always gave them the impression that they would be reasonable and easy to deal with.

In fact, this is also the case.

After the Liao and Song dynasties changed their offensive and defensive forms, the relationship between the two sides did not completely take a sharp turn for the worse.

The Song Dynasty also needed to trade with the Liao Kingdom for a long time and introduce a large amount of raw materials. Therefore, the principle of peaceful diplomacy was adopted, and the two sides opened their borders to deepen trade cooperation.

The economic and trade exchanges between the two sides were very frequent, and there were also many exchanges among the people, resulting in the official relationship seemingly ordinary, but the people were still very warm.

This is a bit like the previous relationship between Song and Japan. There was not much official exchange, but there was a lot of intersection under the prosperous private business.

Moreover, the military power of the Song Dynasty was strong at the moment. If the Liao people ran to the west, they would die. If they ran to the east, they would die even more. The north was the direction where the enemy was coming. Only if they went to the south, they would have a glimmer of hope.

The fact was just as the Liao people guessed. Basically, the Liao people crossed the border and fled. The Song army did not drive them away. They just gathered them together and detained them in the local military camps of various states and counties, waiting for the court to decide.

Now the Political System Council is in charge of the military and political affairs of the country. This war is not only about the fate of Liao and Jin, but also about the diplomacy of the Song Dynasty. Therefore, how to deal with it has never been something that can be decided by the local government.

However, just after the first day of the new year, that is, the third day after the Liao Dynasty's Zhongjing Dading Prefecture was captured, Shengji, located north of Ande, sent a message, which cheered up the pacification envoy and the transport envoy of Youyan Road.

The Liao emperor, Yelu Chongyuan, crossed the Daling River. He and his family members were embarrassedly passing through a forest and were met by the local garrison. They were politely invited to the county government of Shengji County.

Youyan Road originally planned to make a big fuss after Yelu Chongyuan's death, and find reasons and excuses to go north to destroy the Jin Kingdom, so as to achieve a situation where the fisherman gets the benefit.

But catching the Liao emperor is another matter.

Although Liao and Song did not declare war, the wars between Liao and Song before were basically initiated by Liao.

If the Liao emperor was taken to Bianliang and the current emperor was asked to punish him, it would be a great honor for the officials of Youyan Road.

The officials of Youyan Road quickly reported the news.

Not long after, just a few days later, the court sent a receipt and asked them to send Yelu Chongyuan to Bianliang.

Just after the New Year of the 14th year of the Qingli Period of the Song Dynasty, a piece of news quietly appeared in the newspapers: "The Liao Kingdom was destroyed by internal rebellion, and Emperor Yelu Chongyuan surrendered to the Song Dynasty with his family."

Then, the propaganda machine of the Jinzouyuan, which was equivalent to the Propaganda Department of later generations, began to be fully activated, and various newspapers of all sizes published various news.

Some said that Yelu Chongyuan wanted to offer the northern territory of the Liao Kingdom to the Song Dynasty, and some began to argue that since the Tang Dynasty, the northeast has been the territory of the Han people, and the Song Dynasty inherited the orthodoxy of the Tang Dynasty and should also have the right to inherit the northern territory.

Various rumors were flying all over the sky.

When Yelu Chongyuan arrived in Bianliang and heard these news by accident, he could only sigh. When he was received by the Emperor Zhao Zhen of the Song Dynasty, he knelt on the ground with his forehead on the ground and offered the entire territory of the Liao Kingdom to the Song Dynasty.

Under normal circumstances, as a king of a fallen country, Yelu Chongyuan had already lost his country and had no right to do so. Even if he did, the Song Dynasty would not be able to receive these territories.

But that refers to the situation where the strength of Jin and Song Dynasty is not much different. Now Song Dynasty has everything ready, only lacking a great reputation, and Yelu Chongyuan gave it this reputation.

So the next thing is very simple.

Zhao Zhen waved his hand, and the Privy Council and the Ministry of War took action immediately, sending three lieutenant generals to Youyan Road to lead troops and attack Huanglong Mansion directly.

Under the policy of strengthening the trunk and weakening the branches of Song Dynasty, although there are more than 100 major generals, each major general in the garrison can only command 5,000 people. In addition, the system is different and there is no dual leadership of the political commissar, so the procedures for mobilizing troops are very complicated.

In addition to the conventional mobilization methods of the Privy Council, the Ministry of War and the emperor, the second mobilization method is one of the "Basic Law of Territorial Defense" promulgated by Song Dynasty a few years ago.

That is, if there is an invasion by foreign enemies and the court cannot give instructions in time, local political officials and generals can follow this law to lead troops to resist foreign enemies.

This means that the conditions for generals to lead troops are very harsh, so as to prevent the occurrence of Park Kaka's incident.

And the generals stationed in other places are only major generals, and the rest of the lieutenant generals and generals are all in Bianliang. Unless they encounter a very high-level battle, it is basically impossible to dispatch them again.

But it is obvious that destroying the Jin Kingdom is not a particularly high standard. Even if it is a war of annihilation, only three lieutenant generals are sent, and they are all for the purpose of decentralization, otherwise one lieutenant general is enough.

Soon, in the early January of the 14th year of the Qingli period, the Song Dynasty announced to all quarters that the Liao Kingdom offered its territory and the Jurchens established a country without authorization as a rebellion, and officially went north to attack the newly established pseudo-regime of the Jin Dynasty.

This reason seems strange to later generations.

The winner is the king and the loser is the bandit.

The Liao Kingdom was destroyed by the Jin Kingdom, so the Jin Kingdom should inherit the territory of the Liao Kingdom.

But in ancient society, especially in the East Asian Confucian cultural circle, the emphasis is on the righteousness of the monarch, the minister, the father, and the son.

The Jurchens used to be the people of the Liao Kingdom. Now they are rebelling, which is disloyal to the Liao Kingdom.

In name, the Liao regime is recognized by all parties. The Liao Kingdom offered its territory, so the territory should belong to the Song Dynasty. It is reasonable for the Song Dynasty to attack it in this name.

Of course.

In fact, this is just an excuse. There are too many rebellions in ancient times. Cao Pi usurped the Han Dynasty, Sima usurped the Wei Dynasty, Liu Yu usurped the Jin Dynasty, and the Tang Dynasty also rebelled against the establishment of the Sui Dynasty. Can their legitimacy be denied?

So in essence, whoever has the bigger fist has the right, but since the four countries are now vassal states of the Song Dynasty, they need such an excuse to justify their actions.

When Wanyan Wugunai of the Jin Dynasty learned about this, he was naturally shocked and hurriedly sent an envoy again to write a sincere letter, saying that he had never thought of being an enemy of the Song Dynasty and was willing to become a vassal state of the Song Dynasty after the founding of the country.

However, as the saying goes, the bigger fist has the right. Now the Song Dynasty is powerful, and the Jin Dynasty is afraid, so of course it will be humble. But if the Jin Dynasty finds that the Song Dynasty is weak and can be bullied after destroying the Liao Dynasty, how could it miss the opportunity?

Isn't this the case of the demise of the Northern Song Dynasty in history?

Therefore, the Song Dynasty did not pay any attention to the Jin Dynasty at all, but instead sent 30,000 troops from Youyan Road, and then coordinated with more than 10,000 troops from Yunshuo Road and Liaoyang Prefecture, and advanced in three routes.

After two days of discussion, Wanyan Wugunai, who was dominating in the Zhongjing Dading Prefecture of the Liao Dynasty, did not choose to fight hard, but planned to lure the enemy deep into the country.

It must be said that he was wise, just like the Ming Dynasty's extermination of Nurhaci. Nurhaci did not fight hard, but chose to retreat first, lure the enemy deep into the country, and then defeat them one by one, and won a great victory in the Battle of Sarhu.

Unfortunately, the Song Army was not the Ming Army. Although the Song Army still had major problems in overall command, such as the three routes were led by a total of five lieutenant generals, and there was no main general to unify the command of the battle, resulting in each fighting for itself.

However, in the absence of unified command from the upper echelons, the intermediate combat units, each consisting of an army, were well-equipped and well-commanded. Basically, a lieutenant general led two armies in combat, and one army was commanded by a major general, totaling more than 50,000 people, working together to encircle the Jurchens.

The first troops to go north were those stationed in Liaoyang Prefecture. They adopted a method of fighting with overwhelming force. The army marched north along the main road. In just a few days, they first broke through Shenzhou, and then took Guide without stopping, and headed straight for Huanglong Prefecture.

Wanyan Wugunai immediately mobilized a large number of troops to evacuate the hinterland of the former Liao Kingdom, and then in Tongzhou, which is the area of ​​Siping City in Liaoning Province in the future, he planned to take advantage of the terrain and intercept the invading Song army halfway.

But what made Wanyan Wugunai collapse was that the army did not even reach the ambush point. A large number of Liao army surrendered soldiers heard that they were going to fight with the Song army, and most of them ran away halfway. Many even killed the Jurchen supervisors who were supervising them and fled in all directions.

After all, the number of Jurchens was still less than that of Khitans, and being obedient after being captured was a blind obedience effect caused by the natural fear of Jurchens. But once the fear of the Song army prevailed in their hearts, the fear of the Jurchens was naturally overwhelmed, and they fought desperately.

Compared with being shot to death by the Song army hundreds of feet away on the battlefield, or being bombarded by cannons several miles away, they would rather fight to the death with the Jurchens whose main weapons were still cold weapons, in exchange for a glimmer of hope.

At this critical juncture, Wanyan Wugunai had no way to deal with such a thing. In fact, even the Jurchens themselves were panicked, let alone the prisoners?

So he could only bite the bullet and continue to march.

After finally arriving at the place, arranging the ambush position, listening to the scouts report the enemy's movements, and waiting for the Song army to come.

As a result, just as I saw the figure, I suddenly heard a faint "咻咻咻咻咻" sound from one or two miles away.

Then

"Bang bang bang bang bang bang bang!"

The Jin people were stunned by the mortar explosion. They didn't know what was going on. There were explosions all around, as if the surrounding mountains and hills were going to be flattened.

It can only be said that this is only a light mortar developed in the first generation, weighing more than 200 kilograms, and the longest range is only one kilometer.

During World War II, the range of the Japanese 94-type mortar could reach four kilometers, and the 96-type and 4-type mortars with a range of two or three kilometers were also standard.

In comparison, the weapons of the Song army were still somewhat different from those of the more advanced industrial countries during World War II.

But compared with the Jin Kingdom during the cold weapon period, the situation was completely different.

The Jin army had just seen a figure from afar, and it was the scouts in front who saw it. The main force behind was still in the ambush circle. Even the people could not be seen, and they were baptized by artillery fire.

Then a large number of Song troops came, and the sound of gunfire continued, and there was even the sound of machine guns with blue flowers.

The bullets all over the mountains and fields splashed countless dust and startled countless screaming Jin troops.

In just a dozen seconds of artillery coverage and gunfire, the ambushed Jin army could no longer hold on and ran away one after another. The cavalry troops in the rear ran away even faster.

At this time, the Song army, which was a mile away, arrived at the battlefield more than ten minutes later.

They themselves did not expect the battle to end so quickly. The leader, Major General Yang Wenguang, only observed the enemy's ambush circle with a telescope on the mountain, and then asked the mortar team to bomb in that direction.

After the mortar bombing, the infantry rushed again. The two sides were very far away, and there was no actual confrontation or close contact. The war was over.

This is the absolute advantage of industrial countries over nomadic peoples who are not even agricultural countries.

The Jin army was defeated in one battle.

The total war was a battle in Tongzhou where Yang Wenguang had 5,000 men.

After that, the main force of Youyan Road and the Liaoyang Prefecture gathered in Huanglong Prefecture and began to attack Huanglong City, the capital of the Jin Dynasty.

Historically, after Wanyan Aguda established the Jin Dynasty, he first settled in Duning Prefecture, which is the Harbin area, because this is the old nest of the Wanyan tribe, and then began to expand outward.

Now that the Liao Dynasty is very weak, Wanyan Wugunai's situation after the start is much stronger than Wanyan Aguda. He has already controlled most of the northeast and established his capital in Huanglong Prefecture.

So now Huanglong Prefecture has become the center of the Jin Dynasty, and Wanyan Wugunai also fought all the way from here to Changchun Prefecture, and then went south to destroy the Liao Dynasty.

But now the glory has only lasted for less than half a year. The Jin Dynasty quickly declined and was besieged by the Song Dynasty.

Half a month later.

In early February, the Song army surrounded Huanglong City tightly.

Wanyan Wugunai chose to surrender.

He didn't want to fight with the Song Dynasty in the first place, but now he was forced to fight, so he could only surrender.

From the time the troops were sent out in January to the demise of the Jin Dynasty in February, it took less than a month.

In fact, the Song army was almost on the road during this month, and only fought a small battle. The rest of the time was spent marching northward.

The Jin Dynasty was destroyed so quickly.
