Chapter 554: The Castle

However, the Mongols like to use siege bombs, lime bombs or even arsenic poison bombs, so they have to be guarded. Since they studied the siege equipment of the Oirats, it is much easier to do targeted defense, which is Kaiyuan Military Academy.

The great value of the Oirats was to restrain the Oirats' siege equipment, so Kaiyuan Town Army could do it. Therefore, Baicheng was stationed with a sniper team of more than 500 people, and was good at using large guns to restrain the Oirats'

Crossbow.

The gun lift can restrain the crossbow. The effective range of the crossbow cannon is about a thousand steps. The range of the gun lifting of the Kaiyuan Town Army is two miles, and the hit rate within a thousand steps is not low. If it is a carefully selected gunner.

It should not be difficult to hit a huge crossbow within a thousand steps. After all, it is a dead target that cannot be moved. Kaiyuan Town Army's large gun is equipped with a Qianli Milestone, and you can use the Qianli Milestone to observe the bounce point.

This is very sharp. Don’t underestimate the combination of lifting the gun and the Qianli Mile Mile. The so-called practice makes perfect. This primitive combination falls into the magical sharpshooter, and its power is also extremely amazing.

The projectiles are released quickly enough, and the ballistic can be corrected through the Qianli Mile Mile Mile, and sniping within a thousand steps is possible. Two hundred large guns and elite sniping camps are the crossbows used by the Ming army for the Oirat army.

The prepared backup is hidden in the hidden soldiers cave under the wall, and you can fight on the city wall at any time, which can leave a profound lesson for the Oirats.

As a major grassland town, Baicheng is considered a strong city after several renovations.

The walls of Baicheng have been expanding again and again. Now there are two walls inside and outside, including Weng City. Baicheng is not afraid of fire attacks. There are basically no wooden buildings in Baicheng. The newly expanded city walls are earth and stone structures. The earth and stone structures of this era are also

It cannot be underestimated that the fort with earth and stone structures are extremely strong, and the embankments of large rivers are also earth and stone structures. It can be imagined that their solidity is no less than that of the fortresses in the West.

In fact, the border military forts of the Ming Dynasty had many similarities with the Western forts.

The newly repaired Baicheng has a design that is close to the bastion style, which is a new type of city defense designed by Macheng. The essence of the city is nothing more than turning the city wall from a plane to a concave polygon. Such improvements have enabled the attacking party to

No matter which point you attack, you will suffer multiple blows from multiple crossfire surfaces. The hollow basin outside Baicheng is a high platform piled up with earth and stone, and it gradually tilts from behind the cannon base.

A chest wall is arranged on the fort, with cannons and musketeers behind it, and there is a concave surface in the middle of the fortress. This concave surface is very knowledgeable, and it can effectively prevent direct artillery fire. There is a Triangle Fort in front of the main fortress, and Triangle Fort is more important than the main one.

The fort is lower, which is to facilitate the cannon firing. At the same time, the Triangle Fort is also equipped with small cannons. The entire fortress system is filled with earth and stone structures, and the outside is a thick layer of soil.

Because the thick soil layer can attract energy and avoid the bouncing of shells and stone bombs causing huge casualties, the newly expanded part of the outer periphery of Baicheng from a distance is a regular polygon. This is also the first time that Macheng has put the bastion design into application.

It was also a bold attempt. As a bastion-style fortress, the biggest feature of Baicheng's outer wall is multi-layer defense. Because its exterior wall is oblique and short, it is extremely difficult to be hit by long-range artillery.

Of course, Macheng knew very well that the development direction of the fortress in later generations was to take into account both defense and firepower, but it was not yet reached.

In addition, in the fortifications outside Baicheng, craftsmen also used a large amount of Sanhe soil and Sanhe soil, allowing Macheng, a time traveler, to experience the intelligence of the ancients again. Sanhe soil was made of lime, clay, river sand, tung oil, and glutinous rice slurry.

The sturdiness of Ma Cheng was also stunned. This thing is much harder than cement. This thing uses lime, and the ratio of clay is four or six, river sand accounts for about 10%, and a little tung oil and glutinous rice slurry is also added.

After repeated use of a wooden hammer, the solidified three-combined soil was extremely hard. A strong soldier swung the large iron hammer and swung more than a dozen hammers with all his strength. The solidified three-combined soil was completely unharmed.

The city was amazed. This thing was originally used by the ancients to build fortresses. In terms of strength, it was almost as strong as cement. Naturally, it was very luxurious to build a city wall with three-piece soil, but it was worth it.

This thing is so strong that there are many tombs made of Sanhe soil, which have been intact after thousands of years.

In the morning, a 150,000 Oirat army set up camp and prepared to attack the city.

Looking out from the walls of Baicheng, the dense tents were endless. First, there were lines and then they were connected into pieces, and there were Oirat soldiers camping everywhere. Just after the Si hour, the Oirat army launched an attack on the city and used three at a time.

Ten thousand troops, 30,000 Oirat soldiers who were dismounted to attack the city carried the crossbows and dragged the catapult to move forward slowly. Time seemed to retreat to the era when the Mongol Empire swept the world three hundred years ago.

The city was in a state of chaos, and the defenders, mainly Mongolian soldiers, began to prepare for extinguishing the fire. Stone bombs could not be obtained on the grassland, so the Oirat army would most likely launch tinder bombs with catapults. Sand, water tanks, and a large number of people were prepared in the city.

Ready to put out the fire at any time. The military rations are strictly protected. Most of the food and drinking water are buried deep underground. Today, Baicheng is becoming more and more like a military city, standing on the fortress at the east end of Korqin. A Baicheng and Kaiyuan City

The two giant cities firmly clamped the entrance to the Korqin grassland like two iron pliers.

Outside the city, 30,000 Oirat soldiers dismounted to attack the city left their formation, dragging hundreds of catapults, and a thousand of them slowly pressed on them. From a high point, the catapults were in front and the tall catapults were behind.

Behind are rows of hand-held hard bows and arrows pointing to the Oirat soldiers on the ground. Mongolian soldiers will line up in battle, but the queue is not very strict, and they are lined up in a horizontal line to form a coverage when shooting. Those rows of people are wearing

The leather-armored Oirat soldiers advanced together on the grassland, which was very spectacular.

Lu Xiangsheng was not in the mood to appreciate this spectacular scene, but hid in the sturdy main fort. The main fort in the west of Baicheng is the largest, and it is a hollow bastion. The solid exterior wall can accommodate thousands of war soldiers, and it is also a sturdy one.

It is not crowded. This hollow prism is very suitable for grassland cities, because the grassland is empty and there are no stone bombs for use in trenchers, so there is no need to worry about being destroyed by stone bombs. In order to strengthen the defense of Baicheng, Macheng has also taken some effort.

With painstaking efforts, even the 30,000 Mongolian soldiers guarding the city also installed a large number of Atomic Children in the middle.

Standing in the solid hollow fortress, the generals watched the Oirat army stop five miles away and began to set up a catapult.

The huge catapult seemed to be a giant standing on the grassland, with its teeth and claws and five forces, which was the limit range of the three thousand kilograms of França. The cannon outside the fortress was busy, and the gunner was busy loading the three thousand kilograms of França.

When the Oirat soldiers were about to throw the stones, they fired fires one after another. With the whistling sound, huge cannonballs cut through the sky and smashed on the desolate grassland like a meteor, jumping and bounced up, and only one of the four cannonballs hit.

The shell hit the shell and actually crossed the tall catapult and smashed heavily into the Oirat archers' queue. After several bounces, it actually penetrated more than ten Oirat soldiers before exhausting their kinetic energy. The offensive and defensive battle finally occurred, and the busy inside and outside the city
