The strength of the fortress is something that anyone can see, ordinary generals will only focus on the fortress itself, Di Qing and these generals, they are the leaders of the entire Northern Song Dynasty, they see the things behind the effect of this fortress, and the things related to the future war pattern.

In the Privy Council, Jia Chaochang may not have pointed it out, but in the exchanges below, almost most of the generals understood Jia Chaochang's purpose, that is, to launch an attack on Liao in Hebei.

While feeling Jia Chaochang's boldness, these generals were also eager to try, even the most stable Di Qing also talked to Jia Chaochang about the conditions, and they had simply talked about it, he would make a future war plan on the basis of the fortress.

In the first thought, this plan, with great flexibility, was very flexible, and at the strong request of the privy envoy, he looked for an opportunity on the border, provoked, with the help of the terrible longbow, to achieve one or two victories, and if there was an opportunity, to go further, to go further, and if not, to retreat.

This is a very flexible, even if it is 150 miles into the territory of Liao, it is also entered, regardless of the grassland or the city, even if it is just to show the intention, it is enough to solve the problem, even if Jia Chaochang is not satisfied, there is no way, he must be responsible for the soldiers under his command, he will not invest endlessly, and risk failure.

When the longbow entered the Northern Song Dynasty Forbidden Army, the Forbidden Army had a head-on confrontation with the heavy cavalry of the Western Xia and Liao States, it was only a confrontation, and it would not be as weak as the previous infantry armor, but it was only a confrontation, and there was no overwhelming advantage, at most it was offensive and defensive against each other.

Maybe under the ignorance of the Liao State, it will put a certain amount of pressure on the Liao army, and even achieve some victories on the battlefield.

Looking at the results in the middle, if he can really take advantage, he will definitely expand the results without hesitation, but if it is a stalemate or unfavorable degree, he will not attack blindly.

But it is almost impossible to rely on this, completely defeat the Liao State, and even capture some important capitals of the Liao State.

However, with the fortress, everything is different.

One would say that a purely defensive weapon like a bastion would be beneficial for offense?

On the surface, it really can't, the fortress is a defensive weapon, as long as the other party doesn't attack, then he won't have an effect, but his existence can change the original defensive method, that is, after using the fortress, it will be more stable.

This means that with fewer men, you can defend these lines, which means that more troops can be freed up.

Before, Di Qing's foothold was that they were summoned to the Privy Council generals, almost these people, at most about 100,000 forbidden troops, among them, most of them may have participated in the war at the beginning, and then continued to attack, maybe only thirty or forty thousand people, they have to deal with the pressure that Liao may bring at any time.

Now, with such a terrifying defensive weapon as the fortress, these forbidden troops not only do not have to stop to continue defending, but they can also mobilize some of the defenders who were originally in charge of the border.

The Hebei front line is the most important defense system of the Northern Song Dynasty, and this part of the garrison is very large.

In the past, for fear that there would be fewer garrisons and would be attacked by the Liao State, even when the situation in the northwest was at its most critical, the garrison in Hebei was rarely mobilized, or if it was mobilized, it was quickly replenished.

Now, with the defensive strength of the fortress, the place where one army was originally stationed can now be stationed one battalion, which is not bad, which can save 8 percent of the troops.

8 percent of the troops, for an army is not much, but for the entire Hebei defense line, it is very terrible, three or four hundred thousand forbidden troops, how much can be saved, even if these saved parts, will not leave completely, at least about 150,000.

The number does not mean everything, but when the Northern Song Dynasty was in Renzong, the Hebei forbidden army was very well-trained, and Di Qing did not have much confidence before, just because he led thirty or forty thousand people, facing such a behemoth as the Liao State, the lone army went deep, and the possibility of failure was very high.

But now, maybe 300,000 troops have been mobilized at once, which is close to 4 percent of the entire Northern Song Dynasty army, such a strong army, and such an epoch-making weapon as a longbow, it can definitely go further.

Don't underestimate the combat effectiveness of the Northern Song Dynasty, many people feel that in history, the Northern Song Dynasty was relatively sad, blackmailed by the Liao State, and harassed by the Western Xia, almost all of them were in a state of passive beating.

But if you look at the battles of the Northern Song Dynasty, there were several times when more than 200,000 troops were used.

The three battles of the founding of the Western Xia, which of Han Qi's most humiliating battles of Shuichuan was 10,400 and 4,500 people, the former was in the most unfavorable state of food and shortage, surrounded by the superior Western Xia 100,000 troops, and fought fiercely for a day, which finally failed.

The 4,500 people behind were rescuers, and he arrived at it, but the final number was too small, and the main force that ran into Western Xia was also defeated, leaving only more than 1,000 people to flee back.

If this rescue army is not 4,500 people, but 45,000, or even 145,000, what will be the result, if it is really 45,000, these forbidden troops, even if they confront the 100,000 army of Western Xia, will not fall behind.

If it is 145,000, then let alone use more than 10,000 people inside as a block, surrounded outside, maybe, a battle of gathering and annihilation will start.

It's a pity that among the Three Kingdoms, the Liao State has always been biased, as long as the Northern Song Dynasty moves to the Western Xia, they will not be idle, either to put pressure on the Northern Song Dynasty, or to benefit, so that the Northern Song Dynasty's garrison in Hebei has never dared to make a big move, which is one of the reasons why the Northwest is stretched.

Otherwise, with the national strength of the Northern Song Dynasty, if you really grit your teeth, you may not be able to support the 200,000 forbidden army, and go to the northwest battlefield, 200,000 heavily armed forbidden army, as long as there is enough food support, Western Xia is not an opponent at all.

It's a pity that history has no ifs, and now, happier things have come to the head, it turns out that Di Qing is just preparing, just a little temptation, and controlling the war to the extent of friction, which can be regarded as a return to Jia Chaochang.

But now, with the longbow to increase the attack power, and the fortress to increase the protection power, no matter whether you win or lose, it is impregnable, and the room for use is very large.

The 30,000-person forbidden army is a use plan, and 300,000 people are another, even if these saved forbidden troops will not be put into the war against Liao, it will be very terrible, as long as there are 100,000 forbidden troops, or the forbidden army that has undergone the longbow transformation, and the destructive power brought by the northern battlefield is absolutely different.

Yanyun Sixteen Prefectures, this is a dream demon, it is the entire Zhao and Song royal family, coming from Taizu Taizong, everyone wants to take back such a place, this is the hope of every emperor, and it is also the idea in the hearts of all military generals.

If Di Qing didn't have any idea about Yanyun Sixteen Prefectures, he wouldn't push to come here and take a look here, just to grasp all the possibilities in his hands to give better effect.

Such a place that has plagued Zhao and Song for decades and a place of temptation for several generations of emperors, for civil officials, he may have to show integrity, or personal ambitions, and may not follow the emperor's wishes.

However, the military generals must follow the guidelines of the imperial court, and the will of the emperor will be the policy of the military generals.

Several generations of emperors have not realized their wishes, even if they can't take all the sixteen states of Yanyun, as long as they make a little breakthrough in the sixteen states of Yanyun, even if they just take one state, for the entire imperial court to shake, for a general, it is the supreme glory, even if Di Qing is calm and calm, he can't refuse this temptation,

A general, what he hopes most is to make military exploits, Feng Tang is easy to be old, Li Guang is difficult to seal, this is the misery of the general, and the same is true for Di Qing, seeing Han Qi so hot in the northwest, it is a lie to say that he is not envious, now, there is a chance of victory at least eighty or ninety, why not do it.

The soldier is fierce, on the battlefield, all the opportunities are fleeting, there is rarely such a stable chance of victory, even if it is the former champion Hou, when he went out to fight, he also held the determination to become a benevolent if he did not succeed, he would not have thought that Yu Linwei's combat effectiveness almost crippled the Huns.

The victory in front of him may be an illusion, for example, Fu Jian's defeat, no matter what, all aspects of the personnel are far above the other party, but unexpectedly defeated.

But now, the longbow against the field, the protection of the fortress, the worst, that is, the army that goes out to fight, if there is a little problem, it will not affect the stability of the Northern Song Dynasty, and there is a sharp weapon for attacking the city, as long as it can hit the side of the city, it is nine out of ten to conquer the city.

In the war, the two most difficult problems have been solved, one is to attack the city, the other is to defend, and the rest is only field warfare.

This reduces all the variables to a minimum, even if it is the era of the former Burenjia, the field battle on the fixed battlefield, the Northern Song Dynasty will not be worse than the Liao State, the only difference is mobility, once the war starts, the other party can avoid the fight, directly harass and fight, in this case, it will be very uncomfortable, and it is a big deal to fight, and it is impossible to catch up.

But now, even if the cavalry of the Liao State still has an advantage, but the choice of the battlefield, in the Northern Song Dynasty, the Northern Song Dynasty can attack casually, you run, you can, don't chase, I will directly attack what you have to save, for example, these cities in the sixteen states of Yanyun, even including Zhejin Mansion.

This later generation of Beijing, in the Liao State, for the first time, became the capital of the whole Central Plains, became the most important place in the entire Central Plains territory, he is not only the Liao and Song Dynasty to deliver the New Year's coins, but also the Liao State's money bag.

The output of the entire Yanyun Sixteen Prefectures, as well as some transactions in the Northern Song Dynasty, as well as some simple handicraft workshops, blacksmith shops, etc., are distributed here, and these technical jobs are not understood by the Khitans on horseback, and only Han people can master them.

One Yanyun Sixteen Prefectures is enough to cause a shock in the political arena of Liao, not to mention Zhejin Mansion, this increasingly important city, among the four capitals, is also second only to Shangjing, and even in terms of urban pattern and city scale, Shangjing may not be as strong as Nanjing.

These big cities, in front of gunpowder, not to say that they are paper-paste, but they are not much different from paper-paste, as long as the army of the Northern Song Dynasty can reach the side of the city and can dig at will, half a month later, the city will be taken

Such a method of blowing up the city wall, maybe used too much, will also be found by the opponent to find some rules, maybe, to find some ways to crack, the Northern Song Dynasty and Jia Chaochang's requirements are not high, not to take all the sixteen states of Yanyun, not to smash Huanglong, attack the capital of Liao, as long as it occupies a little cheap, sixteen states, take two or three, or even four or five, this should not have any problems.

According to Han Qi, the construction cycle of a fortress is about 40 days, and this 40 days is completely completed, and it is solid, but if it is accelerated, 30 days can also come in handy, and even half of the low-intensity war, there is no problem, even if the cement is not completely dried up, but this viscosity is far higher than that of rice soup mortar.

That is to say, if preparations are made from now on, the Privy Council will specially adjust the entire northern defense line, build this fortress in a unified manner, and then transform their marches, and spend two months to familiarize themselves with and build, and finally mobilize, and this can be sent after the beginning of spring, and the results can be seen within half a year at the latest.

This is probably the first large-scale offensive military operation of the Northern Song Dynasty since Taizong, once successful, even if it occupies one or two states of the sixteen states of Yanyun, the world will be shaken, and the Northern Song Dynasty, which has always been pressed and beaten by the Liao State, suddenly has the ability to counterattack, or under the premise that the entire Liao State occupies the Western Xia, the impact on the two countries and the people's hearts will also reach a certain extent, and even change the pattern of the entire Central Plains.

It took more than half an afternoon to carefully understand the situation of the fortress, and the harvest was huge, and in the end, Di Qing didn't even use his brain to memorize, but took out something to record, even if it was not neat handwriting, there were all kinds of marks like ghost drawings, which was what Di Qing himself knew, and recorded all the key points of the battle in the fortress.

Everyone else has done almost the same thing, if you say that before coming to Baozhou, there are still some doubts, what scale will this northern war be fought, now, with this fortress, everything in the future has been decided, and it is inevitable to enter the fortress of the Northern Song Dynasty military sequence, how can you not understand it clearly.
