Just as the emergence of gunpowder changed the city defense system and the construction of cities in Zhuxia, the new city defense that conforms to the nine numbers of geometry and rationality will also bring about a change in the mode of warfare.

After much discussion, these division-level cadres who had been killed on the battlefield and learned in military academies gradually began to ponder the changes in this mode of warfare.

The commander of the Pengcheng Legion said, "If we ask countries to build new cities in the border areas, we will have to consider the issue of reinforcements from the princes. ”

"Let's still take the Qi War five years ago as an example, if the Qi people had already built forts in the direction of Wenshui and Jishui back then, and we couldn't attack it for the time being, we would give Linzi a chance to breathe and gather troops."

"In the same way, fighting on the outside line, we have to think about logistics, and we can't say that we will go around the fortress directly, then we will die."

Sun Wuzi said that the method of using soldiers, there are scattered land, light land, contentious land, handover land, Qu land, heavy land, encircled land, and dead land. The princes fought for themselves in their lands, and they were scattered. Those who do not enter the deep land are light land. I will benefit from it, and Peter will benefit from it, for the sake of the land. I can go, and he can come, for the land. The land of the princes belongs to the three genera, and the one who comes first and wins the people of the world is Qudi. The land that enters the people is deep, and there are many cities and towns behind it, which is an important land. Walking in the mountains and forests, dangers, and frustration, those who are difficult to walk are the land. Those who enter are narrow, those who return from them, and those who can strike at our people are encircled. Those who fight will survive, and those who do not fight will die. Therefore, there is no war in scattered land, there is no end in light land, there is no attack in the land contention, there is no end in the handover of the land, there is no friendship in the Qu land, the heavy land is plundered, the land is encircled, the land is plotted, and the dead land is warned. ”

"If you fight, you will survive, and if you don't fight, you will die. If we ignore the rear and go straight to Linzi, we will fall into death. Death needs to be fought, but if Linzi is also such a city defense, we will have at least half a year to prepare for the siege. ”

"When the time comes, we can't fight, unless the Qi people are stupid and want to go out of the city to fight with us, otherwise the nobles from all over the country will join forces to help, and the princes will send troops to intervene, and we will only have one way to retreat. The troops are under the fortified city, and they can't attack for a long time, and this soldier is also taboo. ”

This is a real problem.

Sishang has always been an imaginary enemy, that is, the princes of the world, and has always believed that in the event of a real war, the princes of the world will inevitably interfere with Sishang together.

The Qi-Mo War was a war of cunning.

At that time, Wei Zhao turned his face, Zhongshan became independent, and Wei and Chu went to war, and Sishang was sure that it was impossible for all countries to interfere, so he went straight to Linzi and forced the Qi army to retreat.

If there is no such external environment, it is absolutely wrong to use troops in that way, and it will even ruin the situation in Sishang.

It is not possible to pin all hope on the internal contradictions of the enemy, which can be exploited, but not as a regular experience.

What the commander of the Pengcheng Army said was a big problem that Sishang might face in the future.

If it is a fortress-to-fortress, similar to the confrontation of Changping in later generations, it is actually a thousand enemies who have lost eight hundred, and it is okay to fight against a country, but it is a mistake to fight against the alliance of princes.

Sishang's strategic conception could only be a long-distance attack to fight a field battle and go around the outer line to annihilate the enemy's living forces.

Once Qi, Wei, Chu, and Han passed through the battle of Dangshan and built several fortresses on the main roads of the Central Plains to block the lines of communication, it would be very bad.

Seeing that everyone else had thought of this level, Six Fingers said, "Actually, it's right to think so." ”

"However, that's what the giant meant."

"Our mobilization system and system determine that we can mobilize more troops than we did 20 years ago."

"Then the role of these towns is going to change. This change is something we have to figure out. ”

"With our skillful siege method, with the superiority of artillery and the ratio of infantry to one, we can capture such a new city in a month."

"However, in the case of siege, the elite field troops and the mobilized soldiers on the second line are actually not much different, at most, they are organizing some elite advance battalions."

"Therefore, if we fight in the future, our mobilization system may become a norm."

"Several field corps, as the main force, are responsible for interspersing and meeting field battles, while the second-line troops are responsible for garrisoning the logistics line and besieging the city."

"It's the same new type of city defense, but the meaning is different."

"If Linzi and Pingyin's city defense systems are the same, then Pingyin and Linzi have the same meaning to us?"

"Pingyin can be regarded as a barracks for Qi people to assemble and go out, a pillar stuck in the transportation and logistics line. But Linzi is the capital of Qi State. ”

"We have to prove one thing through this battle, even if it is a new type of city defense, we can still conquer it in a month, and only by proving this, we can be invincible."

"The second-line soldiers watched the cities on our path, surrounded and fought slowly. The main force goes straight to the place where the enemy must be saved, besieges the city and sends reinforcements, or captures the capital in a short period of time at any cost. ”

"If the enemy does not save us, we can take it; If the enemy is saved, we can intercept him halfway. ”

"The reaction time of the princes' reinforcements is three months faster, and half a year is slow, and in this half a year, the second-line troops are enough to use our siege method to capture those cities on the main transportation routes, and then we will be replaced by the defense and the princes' reinforcements will attack."

"On a three-month cycle, as long as we can do one of two things, within three months the second-line troops can capture the new cities of the main communication routes and defend them for their own use; Second, our main force can penetrate directly into the enemy's capital and besiege and attack. Coupled with the time for the second-line troops to hold on, the combat cycle of our main forces is at most half a year, as long as we can capture the city and defeat the reinforcements in half a year, then we can win. If we can't do it within six months, then we're in a disadvantageous position. ”

'It's a situation where we take the initiative to attack. If the rest of the princes take the initiative to attack us, we will need to delay. ”

"Rely on cities and fortresses to delay the time of the alliance of princes."

"They are not in harmony with the army, and they dare not fight us; There are few people, they dare not go deep and do not dare to fight; There are many people, and they will collapse in the country after two years at most. ”

"So in my opinion, this is still beneficial to us, but there is only one point, that is, after the entire Sishang, we must put the military first, and ensure at any time that in addition to the main force of the field, we can pull up a second-line army of about 50,000 people, which can besiege the city and even organize a field battle."

"This is a matter of the system, and it is also the responsibility of the Sishang Central Committee, since the above thinks that it is beneficial to us, then I think the above has an idea about this matter. We just summarize the pros and cons we discussed, in case there are some things that cannot be considered, and just submit them. ”

In the end, the topic goes back to the system and internal affairs.

The meaning of the six fingers is that since our 50,000 people cannot ensure logistics to bypass the border cities while fighting in the field, then 100,000 people can solve this problem. As for how to maintain 100,000 people, that is what the Sishang Central Committee has to consider, and it has nothing to do with the army.

What the army should do is to be able to win field battles, quickly attack cities, and accomplish operational objectives in a six-month cycle under this strategic concept.

All of this finally went back to Dangshan City.

Sishang often practiced siege battles, but he never fought to capture new cities, and Dangshan was a test.

If it can be captured within a month, then all the strategies can be implemented.

If we can't capture Dangshan within a month, then the idea of capturing Linzi in three months will prove unrealistic, and the entire strategic concept needs to be changed.

In any case, the visit of envoys from various countries is of great significance.

The capture of Dangshan within a month will inevitably drag all countries into an arms race to build city defenses, and prompt countries to change the law to build a standing army, reform the military system, reform punishment, and abandon the city building regulations of Zhou Li, because if they do not change, they will die.

If the main force of the Sishang righteous division can't attack Dangshan, then the princes of various countries want to break through Peiyi, Pengcheng, and the fortified area south of Taoqiu, which has a more rigorous defensive system and a larger number of artillery, it is a fool's dream, and the war will also be controlled within the scope of the Song State, and it will become a standard external intervention war, and it will be mainly field warfare.

After discussing for a while, these people in the army will summarize the pros and cons of the discussion, and they will submit them to the above when the time comes.

Subsequently, the chief of staff made a report on the current situation in front of the enemy.

Because one month is an imaginary time, there is no need to consider field battles and intervention by various countries, and the entire battle will be fought around Dangshan.

Dangshan City is not very big, and the emperor's father, Yue Ling, is determined to defend Dangshan.

And because of the possibility of the princes intervening, he didn't need to think about a long-term siege, he only needed to hold out for half a year.

Therefore, the food problem was not a problem, and the nobles in the army were also convinced that the princes would inevitably interfere, and the morale of the lonely city would not collapse completely.

The previous uprooting and cleaning of the outer line made Dangshan an isolated city, with a total of about 15,000 soldiers and more than 10,000 untrained farmers.

Seven artillery pieces, and a very strong city defense system.

On the Sishang side, after the Peiyi Legion and the Pengcheng Legion joined forces, because Dangshan was only a hundred miles away from Pengcheng, and because of the previous lime trade, roads and some canals had been repaired, and logistics and transportation did not need to be considered.

The two legions, as the absolute main force of Sishang, could participate in this siege, with a total of seven main infantry divisions and 50,000 men.

There are more than 80 copper cannons of various kinds, two engineer brigades specializing in digging pits, and 20,000 second-line retired soldiers who can be mobilized to help dig pits and transport stones, firewood and grass.

Not counting the comparison of artillery, the ratio of infantry with real combat effectiveness is about five to one to six to one.

In the short term, the weather is also good, at least these days do not seem to be cloudy and rainy.

According to the experience of previous exercises, as long as the new siege method can ensure the superiority of artillery, the superiority of engineers, and the ratio of infantry to one, it is enough to capture the city within a month.
