A conference on the Northern Expedition was held in a short period of time, and a total of 350,000 troops were mobilized in this battle, of which the main force near Baozhou was about 200,000 people, who were the main body of the attack, and the other two directions, the original Liao-Song bordering place, and the location of the northwest and Western Xia, were two partial divisions.

The purpose of the two partial divisions is just to confuse the public, and they will probably concentrate seventy or eighty thousand people and fight casually, mainly to attract the attention of the Liao State, not to enter the hinterland of the Liao State, let alone fight with the Liao army.

Even if the army stationed near Baozhou will not fully enter the Liao State, there are about 150,000 people, and it is the same role, not to let the Liao army find out, the main direction of their attack, by the way, defend and consume the forces belonging to the Liao army.

There are only less than 100,000 people who really invaded the territory of Liao, but these 100,000 people are elites, although they are not as good as those carried by the seeds, they are the elites selected from the millions of troops, but they are also extraordinary.

The top few troops of the forbidden army, almost all of them, they are the first batch of central forbidden troops to be redressed, and similarly, their equipment is also fully aligned with the species, maybe there are not so many horse harnesses, they are a combination of infantry and archers, but this part is a horse riding unit.

100,000 people, at least 70,000 horses, of which 50,000 people can form a team of 50,000 people on horseback, this is the main body this time.

As a genius general, Di Qing certainly understands very well that the mobility brought by horses is something that other arms cannot bring.

Longbowmen can't fire on horses, but through training, they can quickly form a military formation, longbows are long-range troops, almost inevitably, there will be heavy cavalry and heavy infantry to cooperate, even if it is a sneak attack, as long as the heavy cavalry can give the longbowmen a little time, form a formation, you can counterattack.

In the past, such a class of troops was easy to be sneak attacked, and the combat effectiveness was almost equal to zero without unfolding, but now, the telescope is expected during the day, which has increased the detection distance several times, and when the daylight is good, even hiding in the woods, the slightest trace can be seen very clearly.

The appearance of the telescope makes the investigation not have to be very close, as long as the field of vision is wide, a telescope alone can, similar to the Romance of the Three Kingdoms, Zhang Fei's practice, tying a branch to the horse's tail, sweeping away the dust, and falling in the telescope has nothing to hide, unless the dust can completely block the traces of people, otherwise, a little trace can be found by the telescope.

This increases the distance of the warning, allowing the longbowmen to ride their horses, and even if they are attacked, it will not have a big impact.

This is very critical for the speed of the march, whether the Northern Expedition can achieve results, this point, Di Qing will not doubt at all, a longbow is enough to occupy enough advantages in the siege field, not to mention, there are bigger killing weapons.

Gunpowder played a vital role in the battle of Xingqing Mansion, if it weren't for Han Qi taking the city wall of Xingqing Mansion in one fell swoop with the help of gunpowder, maybe Yuan Hao's goal was really achieved.

With the help of the thick city wall, the power of the Liao State and the Northern Song Dynasty was consumed, and at the critical moment, the elite soldiers were killed, and the possibility of victory was great, and the worst could also relieve the siege of Xingqing Mansion.

It's a pity that Yuan Hao still lost to the traverser, gunpowder, a force that does not belong to this era, and even in a sense, in the next few hundred years, even if it is a large-scale use of gunpowder, there are not many cases of using gunpowder to directly blow up the city wall, and the real large-scale use of gunpowder to attack the city is in the Taiping Heavenly Kingdom.

Maybe it's the imperfection of the understanding of gunpowder, or maybe the power of gunpowder is not enough to threaten the huge city wall, all of this, in front of Zhao Xin, no longer exists.

The power of gunpowder, what is more clear than Zhao Xin from later generations, even if he has not seen it, in countless film and television works, he will give him the answer.

As for the power of gunpowder, Zhao Xin clearly remembers the formula of perfect black powder, and at the same time, he also knows that the important role of nitrate in gunpowder, whether it is nitrocellulose or nitroglycerin, these can be obtained through chemical synthesis, and then, it is a continuous attempt.

This caused the gunpowder of the Ding Navy, which was extremely powerful, and also became a sharp weapon for the Song army to attack the city.

Han Qi summoned all the generals, saying that it was a discussion, but it was actually an order, and under the pervasive detection, the information of the entire Youyun was sent over.

The sixteen states of Youyun, the most important are Youzhou and Yunzhou, which are not only geographically and at the absolute core, but also the largest and most populous place.

Youzhou, which is the current Zhejin Mansion, was known as Zhuo County in the Tang Dynasty and before, and it has also been one of the core areas in the north since ancient times. Yunzhou is Shanxi Datong Mansion, which was almost destroyed after Yuan Hao's revenge, and the damage was huge, although it was easy to take it back, it was not easy to govern.

At present, there is a partial division there, about 50,000 people, if everything is going well here in Oritsu Prefecture, you can take it with you, if it doesn't go well, then you will not move.

At the meeting, Han Qi mainly talked about the surrounding areas of Zhejin Prefecture, these states, that is, connecting the original, Hebei, Tianjin, and Shandong parts, and finally arriving at Zhejin Prefecture, guaranteeing 8 states and striving for 10 states, and the highest expectation is 12 states.

That is to say, except for the original Shanxi land with Yunzhou as the core, everything else that can be won will be taken.

The Sixteen Prefectures of Youyun, from Shi Jingjiao to the Liao State, to now, it has been a hundred years, and a hundred years of sinking have made great changes here.

Before, in the eyes of Renzong and the entire center, once Wang Shi arrived, then he would definitely be happy, but in fact, under Zhao Xin's reminder and tentative contact, the result was not so optimistic.

Except for a small number of irons who are willing to belong to the Northern Song Dynasty, almost all of them have been developed and become part of the espionage force, and the rest may have some wall grass, and they will help when the Northern Song Dynasty has the upper hand, and it is almost impossible to die for the Northern Song Dynasty.

In the middle, there is also a part of them who have taken refuge in the Khitan, which is also a helpless thing, in a hundred years, the old country and the Han people are unreliable, the Liao State looks down on them, even if it is the Northern Song Dynasty, they also regard them as the north, in this case, they have no choice.

In addition to these dominant Han families, who accounted for the vast majority of ordinary people, their minds disappointed the Northern Song Dynasty even more.

Shengdou Xiaomin, their short-sightedness, as long as they have a bite to eat, they will not choose to resist, no matter what status and future, it is not important to live and eat, they will ignore the arrival of war, and even flee because of the war.

More and more detailed information, so that a lot of layout, more refined, those vague, some of the assumptions of the plan, of course, are eliminated, replaced by nuanced plans.

Such a plan is not adaptable, but it is more targeted in a small-scale regional war.

Youyun Sixteen Prefectures, as an important grain production base of Liao, are also a base of steel, and they are very important in Liao, which is dominated by heavy cavalry.

A considerable number of troops have been stationed all year round, mainly in the vicinity of Sanguan and Nanjing Zhejin Mansion.

However, the change of Yuan Hao caused heavy losses to the Liao State, which also affected here, and the number of troops at the border pass was reduced from 70,000 to 35,000, and the troops of Zhejin Mansion were only 25,000.

Such a team was already extremely weak, but in the past few months, another transfer, from the border pass and Nanjing, each transferred 5,000 people, forming 10,000 people, to support Yunzhou, responsible for the reconstruction of Datong Mansion.

In other words, up to now, there are a total of 50,000 people in the entire vicinity of Youzhou, and even if you add the idle power of tribes and cities in various places, it will not exceed 60,000.

This is the best opportunity, and the entire Northern Expedition campaign is divided into three parts, the first part, concentrate 250,000 troops, all superior forces, enter the Youyun category, besiege the current Liao army on the border 30,000 troops, these 30,000 troops are relatively concentrated, distributed in 4 large battalions, less than 70 miles of range, with the help of cavalry and mounted infantry, at most two days, can complete the encirclement.

The army of the Northern Song Dynasty was not weak, but what was really weak was the local troops, or the kind of troops that had no logistical support and all kinds of materials were very poor.

In the Northern Song Dynasty Renzong era, although there were financial difficulties, they were not yet deaf, and the use of military salaries and eating the military salaries of the forbidden army was still very high, and the overall combat effectiveness was also strong.

Even if it is placed under the premise of a complete field battle, the 30,000 forbidden army and the 30,000 Liao army at the border pass may not win, but it can be done by holding each other.

6 times the troops, the siege of the sneak attack, or with the help of longbows and explosives, even the most conservative generals, under the premise of not using explosives, simple longbows and fire attacks, the Liao army can block for 10 days, which is already considered a super level of performance.

In Han Qi's plan, he would directly use the dead soldiers and rushing vehicles, rush directly to the side of the barracks, place explosives, and then blow up the barracks to close the siege.

This will make the dead and wounded heavy, but for the follow-up, it is excellent, even in a place like Xingqing Mansion, once the city wall is breached, even if the difference between the forces of the two sides is not large, they will eventually flee, not to mention 6 times the number of troops, in a place like the barracks.

According to the plan, at most 3 days, the problem can be solved, and next, 150,000 troops will be nearby, some of them will guard the border, and the other part will go directly to Mozhou and Yingzhou, and take down this protrusion that goes deep into the territory of the Northern Song Dynasty.

Only the 100,000 troops carried by Di Qing will attack continuously, break through Zhuozhou, and after breaking through Zhuozhou, they will face Zhijin Mansion.

The distance in between, between Zhuozhou and Zhejin Mansion, is only 120 li, for the cavalry, a charge, two or three hours will arrive, even if it is from Sanguan to Zhuozhou, it is not more than 150 li.

It is close at hand, and the other party is still negligent in guarding, you must know that in order to prevent the Liao army from going south, in the entire Hebei defense line, a million troops were stationed before.

With the construction of a large number of fortresses, the number of troops gradually decreased, but up to now, the entire defense line still has more than 700,000 people.

But on the other side, the Liao army is really big-hearted, with more than 30,000 people, guarding the entire huge area, which is no longer defending, or watching.

Perhaps, the Liao State has never considered that the Northern Song Dynasty, which is like a soft-footed shrimp, actually dared to counterattack.

Yuan Hao's revenge caused a heavy blow to the Liao State at once, and the population and strength base, all of which went wrong.

Millions of people, this time the foundation of the Liao State has problems, itself, the strength of the Liao State, is built on the Great Khan of the nomads, the princess of all the nomads, but now, Yuan Hao's challenge, so that these positions are in jeopardy, in order not to lose this status, they must send troops to suppress it.

While it is necessary to ensure the strength of Liao Xingzong and Zhongjing, the majority of those who can be transferred must be Nanjing.

In less than half a year, the troops in Nanjing and the border were transferred 4 times, a total of more than 70,000, for this, no Liao important ministers raised objections, they were so poor that they wanted to rob the Northern Song Dynasty, in their opinion, the Northern Song Dynasty was a place for them to extort and plunder, they would not have thought that a little sheep would rebel against a lion.

But now, the Northern Song Dynasty not only resisted, but also premeditated, transferred the domestic elite, and made a lot of arrangements, for example, the key to the Shanhaiguan line, landing on the Liaodong Peninsula.

At this moment, Liao Xingzong is still sending a large army, in the pursuit of the cultivator, he has not realized that the seed is sent by the Northern Song Dynasty, he just thinks that it is the elite made by the Jurchens, and even let the Liao army in the north strangle the Jurchens, and the only mobile troops in the Liao State now, more than 300,000 troops, have been chasing the ass of the Jurchen.

If it is said that the seed is to the south, maybe the Liao army will still be confused, but he is to the north, and the north is the territory that the Liao State really controls, even if it is the Jurchen, it is only in the deep mountains of his tribe, posing a threat to the Liao State, and they are not worried about an ambush.

The pursuit of farther and farther away allowed the only army of the Liao State that could influence Youzhou, and ran thousands of miles more, and their reaction time was greatly extended, which also laid a good opportunity for the Northern Song Dynasty's northern expedition to Youyun.

Although, the subsequent results proved that such a transfer did not have much effect, in fact, the speed of the Northern Expedition to recover Youzhou was very fast, but the subsequent occupation, stability, including the harvest of enough population and capture, these are still useful, basically, these people and wealth near Youzhou have not been transferred on a large scale.

The generals had already been prepared, and the army had been mobilized in place, just three days after the Baozhou Conference, for the Northern Song army, which had been equipped with horses on a large scale, it was not difficult to break through about 70 miles in one day and surround a small Liao army camp, and it was not even much more difficult than paradging the streets.

The Northern Song Dynasty had made all preparations for war, and the Liao army camp across the pass did not realize it at all.
