Gao Pragmatism, who was regarded as a thorn in the flesh by Zasaktu Khan, was actually not particularly calm, because this battle of Sand City was also a new experience for him.

A new experience of being blocked in the city by others and being beaten passively.

But the strange thing is that in addition to himself, he found that most of the people around him were very calm, especially Ma Gui, who was even more relaxed as if he was not in the middle of the war at all.

Gao Shishi, who ran to the top of the Dongcheng Tower early in the morning to check the enemy's situation, couldn't help it, and said to Ma Gui, who had a calm face beside him: "Xiquan, I see that you are very confident in this battle, and you don't seem to take the pictures in your eyes at all?" ”

Ma Gui smiled and said, "Although there are more than 70,000 people in Tumen and Xin Ai, it doesn't make sense, even if you give him another 70,000, it's useless, they can't pose any threat to Shacheng in three months." ”

"How can you be so sure?" Gao asked pragmatically.

This question seemed to be a bit surprising to Ma Gui, and he said with a little surprise: "I defend him to attack, I have a strong city to rely on, and a cannon to kill the enemy." If the cavalry of his army comes and goes, it is certainly above me, but it is difficult to advance an inch under the city, and sooner or later it will leave, why should I worry? ”

Gao pragmatic nodded and said: "You mean, they don't have any effective siege methods, and although they are now besieging the city, although they are huge, they are actually useless?" ”

"Nature." Ma Gui smiled: "Wait and see"

Ma Gui pointed to the Tumen and Xin Aibu cavalry who were camping and surrounding Shacheng far away, and said: "Although they are besieging the city, the location they chose to camp is far away, which shows two things: first, he is afraid that our army's artillery will bombard him, and second, he is afraid that our army will suddenly kick the camp." ”

"Kicking the camp?" Gao asked rhetorically.

Ma Gui nodded and said: "They don't know the movement of our army's troops, and they probably think that there are twenty or thirty thousand cavalry in the city, if there are really twenty or thirty thousand elite cavalry, they will concentrate on a sudden killing camp and kick the camp, and the probability of success is quite high."

At that time, his army of 70,000 was scattered outside the four gates, each gate was less than 20,000 horsemen at most, and if he was suddenly kicked into the camp, there was a high chance of collapse. As for the collapse of the first gate, it is not a good thing for them to continue to pursue and expand the results of the battle, or whether our army will collect its troops and return to the city. ”

"It's a pity that there aren't many cavalry in Sand City." Gao Pragmatic finally put his mind at ease and said with a smile: "It seems that it has disappointed the Great Khan of Tumen." ”

Ma Gui laughed and said, "Let him be frightened, let's defend the city as usual, don't let the cavalry come up from beginning to end, and occasionally let them see something, lest they have any other ideas." ”

Gao pragmatic nodded and said: "Xiquan, your words reminded me, that's right, I still have to let them make sure that there is a main force of cavalry in Shacheng." ”

As he spoke, he turned his head to Cao Gan and said: "Go find two people, one should look like Dacheng Taiji, and the other should look like Alige, and then prepare the honor guard of Dacheng Taiji, especially the flag, and let them occasionally go to the city tower to patrol the city, not too many times, just once a day, and you don't have to inspect for too long, the time for a stick of incense is enough." ”

Cao Gan responded with a smile, and asked again: "Do you want to find another stand-in for Chataiji?" Although it is a bit difficult to pretend to be him, the people of the Tumen are far away and cannot be seen clearly. ”

Gao Shishi had just considered finding an actor to replace Chataiji, but Chataiji's demeanor, especially his eyes, was very difficult to imitate that he was a Jebel Divine Shot, his eyes were sharp, like an eagle and a falcon, ordinary people pretended to be him, and he was out of the play with one look.

However, Cao Gan reminded him correctly, although Chataiji's eyes are not easy to pretend, but the people are far away, and they are not per capita Jebei Divine Shot, can they still see the eyes of "Chataiji" from such a distance?

So Gao Shi thought about it for a while, and also responded, so Cao Gan went down to prepare and began to find someone.

Ma Gui said: "Don't worry about the servants, now our Ming army is the main force in Shacheng, our army is good at defending, and now the fortified city is full of cannons and a lot of food, as long as the Tumen can't turn into cannons, he doesn't want to break into the city." ”

Gao pragmatic nodded, but sighed slightly in his heart.

It seems that the Ming army used artillery as a weapon to defend the city, and it cannot be said that it is Yuan Chonghuan's unique invention, but there are early signs and even traditional, but Yuan Chonghuan's understanding of the use of weapons is a bit biased, so he took the wrong path.

From the late Ming Dynasty to the end of the Ming Dynasty, should artillery be used to defend the city? Gao pragmatic thinks that it can, but this can, it should refer to small and medium-sized guns that can be fired, and even long-range fires, and it is by no means Yuan Chonghuan's defense of the city with Hongyi cannons.

Take Ningyuan City at the end of the Ming Dynasty as an example, the height of the city is 12 meters, and it takes 141 seconds for the shell to be lowered to the enemy's height of 22 meters. Even if the Hongyi cannon shoots at a 0 angle with a muzzle velocity of 360 m/s, even if the velocity before landing is reduced to 220 m/s after 151 seconds, it will form a blind spot of at least 406 meters or more under the city.

So if the small firing angle commonly used in Ming Dynasty cannons is calculated as a minute of 75 degrees and a range of three miles, the blind area is at least 1500 meters or more. 1500 meters away, is it still accurate? The result is naturally that it is far away and inaccurate, and it is close to it! Who can be killed, it all depends on the face.

What's more, after such a move, the angle of incidence of the solid bullet when it lands will definitely increase, and it will be difficult to form a ricochet. And it is even more unreasonable to expect Yuan Chonghuan's red-clothed cannon to form a ricocheting boar skin with a maximum range angle of more than 30 degrees. Because the high-speed steel bullet firing steel plate in later generations had to have a normal angle of more than 70 degrees and a horizontal angle of less than 20 degrees before it could form a ricochet.

Yuan Chonghuan shot more than 30 degrees when he was bigger in the corner, how could it form a ricochet? Could it be that Yuan's cannonball is faster than a modern cannon, Yuan's NN is harder than a steel bullet, or maybe the place where the wild boar skin stands is a super steel plate?

Because of these deficiencies in the artillery of this era, in the work of the NS on artillery, the ideal angle of fire for artillery was set at five degrees: "It is a very unfavorable firing condition to shoot downward or upward on a slope above 5 degrees, or to shoot from the top of one hill to another."

The two main points mentioned in the book of Old Man En, the angle of incidence should not be large and the gun position should not be high, and Yuan Chonghuan actually accounted for all of them.

The fortified cannon that can really go to the city is a small and medium-sized cannon. As for the artillery going to the city and the related division of labor, there is actually a record of the fire attack in the Ming Dynasty: "If the enemy camps from afar, he will use a long battle to attack his camp from afar, so that he does not dare to stop for a long time." And what really kills the enemy is the cannon with a wide mouth: "If the ants gather and swarm to the city, they will use the big cannon to kill the people."

Just saying that some people in the country do not believe it, and continue to take the writings of Mr. NS to say that he also made it very clear in the bastion: "They are built so high that the artillery can shoot from here beyond the breastwork of the bastion." Due to the vantage position of the battlements, the longest-range guns were usually placed in the battlements in order to harass the enemy with artillery fire at a longer distance. ”

Look, in the era that has surpassed the technical level of the late Ming Dynasty, on the fortress that has surpassed the city defense of the late Ming Dynasty, in the battlements that have surpassed the fortress of the late Ming Dynasty, and the cannon that has surpassed the level of the late Ming Dynasty is also used, and the role played is only to harass the enemy with artillery fire!

NS was still in the fortress era at that time, which somewhat saved some face for Yuan Chonghuan's "cannon with a strong city". And in the era of the city walls, in the book of the military science master N Dupuy, the evaluation of the cannon on the city is more straightforward:

"As has already been noted, in part this is due to the inability of castles and walled cities to erect large cannons against enemy shelling. The light cannons on the city walls can't hit the enemy's siege long-range guns, and the heavier cannons, although they can be dragged to the city walls with great effort, can only have the opposite effect. Because the recoil of the cannon will cause a huge vibration of the wall base, which seriously affects the solidity of the wall, it is easier to be breached. "The evolution of weapons and warfare

Look, "on the contrary, it is easier to be breached", this is really even the last fig leaf, which has been stripped off by "using cannons in the fortified city"!

In addition, Gao Pragmatic has always felt that Yuan Chonghuan's power of the Hongyi cannon is exaggerated to the point of exaggeration, at this time, the Hongyi cannon at this time in addition to the rapid rate of fire at the beginning, because of the cooling of the cannon chamber when continuing to fire, the rate of fire per hour is only about about one round, which is still no fault premise. This rate of fire was clearly not able to generate sufficient firepower in the face of a swarming enemy.

In Gao Pragmatism's view, the use of artillery in the era of solid artillery, the first is to siege the city, with large siege artillery, such as the No. 1 and No. 2 guns under the Jinghua imitation system, and the second is to break the infantry dense array, with infantry anti-personnel artillery, such as No. 3 and No. 4 guns, the technical level is a little worse, that is, Qi Jiguang's favorite tiger squat cannon in the field.

As for defending the city, the "giants" of this era such as the No. 1 and No. 2 cannons are better than nothing, and they cannot reach the height of "relying on the fortified city and using cannons".

The "cannon" in Magui's mouth is actually not some kind of actual reference, his meaning is very simple, that is, the artillery cannon that can hit the other party is just used to it.

As a typical firearms party, since Gao Pragmatic has adopted the tactic of flowering in the center of the "self-inflicted death," he certainly cannot but prepare artillery, and in fact he has prepared quite a lot of cannons, including 76 No. 3 guns and 137 No. 4 guns, totaling 2,213 cannons.

However, he did not have an accurate judgment on which gate the Tumen would attack, so the more than 200 cannons were currently evenly distributed among the four towers in the south, east, and north.

Of course, more than fifty guns No. 3 and No. 4 were assigned to each gate, which was already exaggerated in this era.

What's more, he is not only a cannon, he also has a large number of Longqing type 2 fire n, and a small amount of Wanli type 1 fire n, these Jinghua fire n, due to their reliable quality, can be charged in sufficient quantities, the range in this era is significantly beyond the range of ordinary bows and arrows, and the condescending Mongolian soldiers who attack the city are not a problem.

The only question is whether the Tumen will choose to attack.
