Generally speaking, in ancient times, when attacking a city, it was necessary to besiege it at least ten, cut off the source of food and grass for the defenders, and then continue to use the lives of the soldiers below to test and fill the pits, until the defenders in the city were exhausted and showed their flaws, and then swarmed up to capture the city.

Of course, this process can be quite lengthy......

It's just that for Zhu Gaoxian, the siege of the city is actually not a difficult thing.

Although the Ministry of Industry has not yet been able to develop powerful firearms, and the power of Daming's artillery is also very average, Zhu Gaoxian has countless knowledge and experience in his mind, and he has already made people drum out the artillery cart with counterweights.

In addition, this expedition to Mobei, he also deliberately asked the army to bring more than a dozen newly developed artillery guns, ready to experiment when encountering the enemy's stubborn defense.

In fact, there have always been artillery guns in use in the Ming army, but they are all iron cannons fixed on the launch frame, stupid and black, and they are also the most primitive black powder, which is slow to load, small in power, and very average in range.

And because the cannon body is made of iron, not relatively soft copper, these guns often blow up the chamber and directly kill the soldiers on the side, so the army does not have much affection for the artillery.

However, Zhu Gaoxian knew that firearms were the discovery of future development, and they were the reliance and hope of the Ming Dynasty to sweep the world in the future, so he ordered the Ministry of Industry to start further research and development of firearms as early as possible, and also allocated a large amount of additional money from the Ministry of Households.

Although the progress is not too fast, it has finally made some achievements.

For example, the tiger squat cannon that Zhu Gaoxian had in mind was the most commonly used artillery in Qi Jiguang's army in history, this kind of cannon has a light and thin wall, is easy to carry, and has a very flexible and mobile role, and can be fired at a large elevation angle, which is similar to that of modern mortars.

There are also rear-loading cannons similar to the classical breech howitzer, although with the level of craftsmen in the Ming Dynasty today, it is far from reaching that standard, but Zhu Gaoxian asked the craftsmen to reduce the diameter of the cannon barrel, and added the hoop mouth to prevent the explosion of the chamber, all of which are made of copper, and a few of them are also made.

The most important thing is that Zhu Gaoxian also taught the students the relevant knowledge of artillery lugs and sights, which directly made these breech guns have the ability to observe and aim, and the range and accuracy have been greatly improved!

Coupled with the granular gunpowder production method given by Zhu Gaoxian, he successfully made a more stable and powerful gunpowder, and also made a scattered bullet with more than 500 bullets.

And if you replace it with siege shells, a cannon will come down, and the ordinary city walls will have to be blasted out of a big crater!

Therefore, in Zhu Gaoxian's view, the siege is actually not very difficult.

Just let the artillery in the army let go of the boom!

On the other side, Warat, who had just learned how to defend the city, was still a nomadic in nature, and after encountering continuous and powerful artillery covering blows, the army was absolutely in disarray......

"Your Highness, there are so many guns in the army, there are a total of fifty tiger squat cannons, and there are only twenty breech guns.

After Su Wu inspected the artillery position, he found Zhu Gaoxian.

"It's just a small town on the other side, and with the purpose of delaying us, let all the artillery soldiers go out, do you think too much of them......

"Do you want to transfer half of it out and hand it over to the Shenji Battalion to defend the left side of the army? It can also better kill the Warat army that wants to outflank us. ”

When Zhu Gaoxian heard this, he shook his head slightly:

"You don't understand, things like fire cannons are to be gathered together, like a fist that has enough strength, and then give the other party a fierce blow."

"If it is scattered, once the power is not enough, it will not be able to deter these Warats in the city, do you still want the soldiers below to fill it with their lives?"

"Besides, as you can see, the Ministry of Industry has spent countless materials and manpower, and the Communist Party has only built this ignition cannon, and it has never been tested in actual combat."

"The reason why I didn't use them against the Tatars was to see if the real effect of these guns on the army was whether they affected the speed of the march and how much the guns and ammunition were affected by factors like the weather."

Speaking of this, Zhu Gaoxian raised the telescope again and looked at the city in front of him.

"As long as you can knock on the Helin City in front of you and deter the Warat people, even if all these cannons are scrapped, it will be worth it."

"As for the sneaky Warat army that wants to outflank us, the scouts have been keeping an eye on them, and the Divine Machine Battalion is almost at its intended location."

"As soon as the artillery here is launched, the Shenji Battalion will attack them and catch them off guard."

He chuckled, and his tone was full of confidence in the soldiers of the Shenji Battalion:

"With the current strength of the Shenji Battalion, these tens of thousands of Warat troops have traveled a long distance to this point, and they will definitely be able to achieve a great victory."

"Those Warat captives are just used to storm the city and fill the pits, and reduce the casualties of our Ming army......"

Hearing Zhu Gaoxian's words, Su Wu also agreed, indeed, it is much better to let those Warat captives go to fill the pit and send them to death than for the brave soldiers of the Ming Dynasty to sacrifice.

What's more, they still have many Tatar prisoners of war in their hands today, also to play a role in the siege of the city......

"Pass my order, the artillery prepares, and in an hour, fire with all your might!"

"Based on the base of ordinary training, the breech cannon uses siege shells, aims at the city wall, and fires ten rounds first."

"Then the Tiger Squat Artillery Team marched forward, firing fifteen rounds in a row at the longest distance."

"After the breech cannon is finished, use scattered bullets, aim at the place where there are many defenders on the city wall, and fire ten rounds in a row!"

Relatively speaking, the power of the Tiger Squat Cannon is not too great, but it is flexible and mobile, the rate of fire is fast, and it can shoot at a large elevation angle, which is very lethal to the infantry, and it is not easy to dodge if you want to.

And the scattered bullets of the breech cannon, it is really a bullet that blooms on all sides, and if the cannon passes, I am afraid that a bunch of defenders on the city wall will die in Huangquan!

"Get the flag bearers ready, and as soon as our artillery starts firing here, we will immediately pass the flag to the Shenji Battalion, so that they can attack at the same time."

Zhu Gaoxian continued to give orders, and his tone was very resolute and decisive:

"He won't risk rushing out on the other side first, he will definitely wait for the Warat army to come and attack us."

"I'm going to hit this time difference, so that he will lose his wife and soldiers!"
