Muhammad did not agree to Luka immediately because he was not very willing and wanted to try the weight of the Great Xia Kingdom.

Dankoi, Kerch, Serbia, and Bekchisalai are all tall and thick castles. The Kingdom of Daxia wants to break through easily? Even if it can surrender, the major Halachi families under its command will not agree.

The Khanate will not surrender until there is a clear crisis.

He kept Luca, ostensibly asking him to stay for a few more days, but actually preparing for both hands.

...

Kerch Castle.

After pushing ten 48-pound Nibchu bronze cannons near Kerchi City, they first bombarded a wall for three days. Although the city wall was loose, it was very small. According to the artillery commander's estimate, it would take at least one month.

One month, bombarding day and night, the Daxia Kingdom did not have so much ammunition for them to consume. Even if there was one, they would not be able to consume it like this.

One day, Nikan handed over Yalta City to Alina's guard, and he followed Chen Muzhi's fleet to Kerch. This time, he only brought five hundred Lens with five consecutive rifled rifles as his escort, and let Sun Xiulan, the commander of the Shenwu Army, stay in Yalta.

It has been ten days since the Hanhai Army captured Yalta, but there is still no movement on the Black Sea. It seems that Koprolu is preparing to give up Crimea, or he has been secretly observing the progress of the Crimean war. Moreover, the city of Azov at the northern end of the Azov Sea is still in the hands of the Ottomans. Before the Great Xia Kingdom took this place, it will not pose a threat to the Ottoman land.

In addition to Azov City, there are several fortresses on the east coast of Azov Sea, which are not easy to get down.

Coprolu is waiting for a suitable opportunity.

But Nikan was not ready to give him this opportunity. After hearing that Dancoy and Kerch's siege were not going well, he came to Kerch.

When he heard that His Majesty had arrived, Sun Degang quickly came to the dock to greet him.

After arriving at the artillery position, Nikan picked up the telescope.

Ten heavy artillery were specially used to attack the city. In the camera, except for the protruding part of the female wall on the top of the city wall, many of which were destroyed by heavy artillery, the entire wall remained unmoved. After pulling the camera closer, it was discovered that some of the stones were concave into the inside, but it was not obvious. Without a telescope, it was exactly the same. But one advantageous point is that some stones had been shattered by giant shells, but it was probably too thick, and the overall wall still maintained a strict shape.

If the city walls of three to five meters thick are smashed like this, it is possible to cut them off layer by layer. When there is only one stone wall, if there are multiple cannons at the same time, the city wall will definitely fall down, but that will take time.

Nikan suddenly thought of something.

Why did the Spanish build castles, including Manila, so thick? The wall of a military fortress in Haikou is more than ten meters thick. I am afraid it is to guard against heavy cannons on ships. However, in front of the stone city walls of more than ten meters, even heavy cannons are not able to catch them.

As for the way to attack the junction of the city walls like the Qing Dynasty who later attacked Yangzhou City, it was useless here, because the Ming Dynasty's walls were square in square, but the castles, including Kerchi City, were all Greeks before. It is estimated that they had heavy stone bombs attacked the castles in that era. All castles were irregular in shape, that was, there was no obvious junction, and even some places were reinforced and thickened.

Their junctions are all places where troops are stationed, and there are round forts similar to the function of horse-faced walls. In such places, the city walls are at least six meters thick, and it is probably more difficult to bombard than ordinary city walls.

As for using cloud ladders to attack the city, Nikan never thought about it, but under the current circumstances, he had to give it a try.

Before that, there were some things that needed to be asked first, and he called Sun Degang to his side.

"Have you investigated, what is the height of the female wall they are on the city wall?"

"Your Majesty, you don't need to investigate. You can roughly figure it out with a telescope on the observation deck of the camp. About one meter, Your Majesty, their city walls are not like Europeans. Although they are more than three meters thick, they are not enough to place heavy artillery. Their artillery looks good in caliber, but they are all short-barrel cannons and have not had a long range. Because if such a city wall is placed with heavy cannons, its counter-smashing force will destroy the city wall itself. Therefore, we can bombard the three miles away with leisurely distances."

"How far can their artillery hit?"

"The farthest one is Sanli, but there is no accuracy. After reaching Sanli, its momentum will almost fade."

"Their wall is the widest?"

"That's not the case. However, the front of this city wall is the most suitable for placing heavy cannons. Other places are rugged and uneven, and it is not suitable for placing heavy cannons. The width of this place is more than 30 meters, and it is just taken care of by ten heavy cannons forty-eight kilograms."

"Then what part are you aiming at?"

"According to Caodian, it is naturally the middle and lower part. In that case, when a certain place is damaged, other parts can collapse. If it is in the upper part, even if it is bombarded, it will take a lot of layers because it is too high. It will take too time to cut it off. If it is in the lower part, it will take too long."

Nikan cursed in his heart, "The Hanhai Army strictly follows Caodian to carry out any war. Although there is no problem in most cases, there will be problems when it comes to such a siege that rarely occurs."

"When the Ottoman Empire captured Constantinople, giant cannons were fired. Such cannons required two hundred people and sixty oxen to pull them. Naturally, my Daxia did not need such heavy cannons, but you also need to use your brain under the premise that the power of the cannon is limited."

He said to Sun Degang: "Have you observed that how many soldiers can be placed in this section of the city wall?"

"Your Majesty, I have naturally observed that this section of the city wall is about 35 meters long and about three meters wide. It is estimated that at least six meters at the root. Two platoons of troops can be placed to garrison there. One platoon stands behind the female wall and shoots with muskets, and the other platoon is prepared in the back, leaving a pedestrian passage in the middle. This is the largest placement. They arranged this way, and the total number is 60 people."

"On both sides are two places that seem to be junctions, and behind is a round fort. The walls are obviously much thicker than other places. The round fort is also dozens of square meters. There can be a row of garages to support critical city walls at any time. There are doors on both sides of the round fort, which means that even if you attack the wall, they will close the side door of the round fort, and you will not be able to enter."

“That’s very simple”

At this time, Nikan had an idea.

"Let the 48-pound heavy artillery rest for a while, and pull the remaining 32-pound and 24-pound artillery to two and a half miles away from the city wall, and all aim at the female wall and the part of the round fort exposed to the city wall."

"What your Majesty means is to flatten all the weak parts above the ground of the city wall and then attack the city wall?"

"Yes, only in this way can we capture this city as soon as possible. Although our country is rich, we cannot waste time under the city without restrictions. Such a forty-eight pound shell plus ammunition will cost one tael of silver. If it takes a month, three months, or even half a year, the empire will be emptied even if its family is big, and not to mention that the workshops behind may not be able to be consumed, because more on the ship is needed."

"A mere 30 meters of city wall, all the female walls, plus the top of the round fort, can be done within two days! Then let the engineer prepare for the siege ladder!"

Nikan's voice and expression were harsh, so his nephew, Sun Degang, who was also from Uzha's tribe, dared not refute any and went to make arrangements.

Two days later, the cannon that could accurately hit the target four miles away knocked off all the female walls on this section of the wall and the part of the round castle that was higher than the ground of the city wall according to Nikan's requirements, and at the same time, all the short-barrel cannons set up on it turned into scrap iron.

In the past two days, Sun Degang did not only build a ladder according to Nikan's requirements, but instead created a tall siege car.

A siege car with a siege of musketeers up to ten meters high and a squad can be arranged at the top. Unlike previous siege cars, the Daxia Kingdom has invented tires made of rough rubber, and there are six rough rubber tires under the siege car. A total of five such siege cars have been made!

Pulling from the pack horse and under the cover of artillery, the siege car set off. In the past few days, due to the continuous bombardment, there were no female walls on the city wall, only a few soldiers hiding behind the ruins.

There is a thick wooden board at the end of the siege car facing the city wall. When approaching the city wall, it can be used as a cover to shoot. When arriving, the wooden board can be placed down and placed on the city wall.

Each soldier has a musket that can fire five times in a row. Under this condition, it should be a terrifying existence. In the telescope, there are only a dozen remaining enemy soldiers, and there are only Lumi guns and knives in their hands.

"Bang!"

Faced with the sparse sound of muskets and the continuous earth-shaking roar of our cannons, the pedal of a siege car was put down!

A squad of soldiers was divided into two rows, one row of five people, first shot forward for a while, and then jumped up!

Under the attack of fifth series of muskets, the soldiers of these five squads quickly occupied this section of the city wall, but they were not able to continue attacking the other city walls, because at the round forts on both sides, the bricks and stones on the top of the collapsed round forts formed an obstacle about two meters high.

At this time, in order to cover the capture of this section of the city wall, some artillery had been moved to the adjacent two ends of the walls, and a new round of bombardment against the female wall and the top of the round castle was started. Under such bombardment, there was almost no one behind the female wall, and it was naturally impossible to come to fight against the Hanhai Army soldiers who had already reached the city wall.

What's more, after the female wall facing the Han Haijun was flattened, most of the female wall facing the city were still there. In other words, if the enemy designs from the bottom of the city to the top of the city, there is also a female wall that can be protected!

But the enemy is obviously more tenacious than Han Haijun imagined.

At this time, in the Khanate countries near the Black Sea in the Caspian Sea, each castle had a considerable number of "jihadists" willing to devote themselves to jihadism. In order to go to heaven as soon as possible to enjoy countless milk and honey, some were jihadists. The fighting skills of these jihadists were extremely suspicious, and their only advantage was that they were not afraid of death!

These jihadists came up from the inner city with ladders!

The jihadists came up almost at the same time as the Hanhai soldiers. They only had a musket in their hands, and some even had a scimitar!

"Bang bang..."

A small-scale battle immediately appeared on the top of the city. In this sudden encounter, it was impossible to ensure that one side had zero casualties. In the end, 50 people who came up to the city wall sacrificed twenty people. The remaining thirty people guarded this section of the wall, and then used grenades and small cannons to suppress the holy warriors who were climbing up the ladder continuously.

After stabilizing, with the subsequent reinforcements of Hanhai soldiers, it was impossible for the enemy to seize this section of the wall through the counterattack of the Mujahideen.

With this section of wall cover, the Han Hai Army suffered much less casualties when attacking other city walls.

Such a battle lasted for three consecutive days. During these three days, the Kingdom of Daxia had sent the entire brigade of infantry to the walls of Kerch City!
Chapter completed!
