In mid-March, 400,000 troops had gathered under the city of Jinzhou, but there were still troops continuously driving to the city.

The strong military force of the Gan Army surprised Luke Dehun in Jinzhou City. He slept on the top of the city every day, worried that the Gan Army would steal the city.

However, his concern was completely unnecessary. Gao Huan was naturally willing to attack, but Jinzhou's city defense system was too difficult to successfully attack, and it was almost impossible.

Gao Huan didn't want to steal chickens and lose rice. After observing the defense of Jinzhou City, Gao Huan first asked Mandahai Zhishu to surrender. Seeing that Luke Dehun did not reply, he knew that he could only attack.

Therefore, after Gao Huan arrived at the city, he began to command the troops to carry out siege operations, and a big battle was imminent.

After all, Lushun was besieged by the Qing army, and there were 300,000 Mongols who entered Guanzhong. The main force of the Gan army gathered outside the pass and Shandong, and the battle to destroy the Qing Dynasty must be ended as soon as possible.

Anyone who is not afraid of ten thousand is afraid of anything.

In case of Lushun falling or Guanzhong was taken down by the Mongols, it would be a huge loss for Ganchao.

Therefore, although Gao Huan didn't need to care, he still ordered the army to step up preparations for the siege.

At this time, at the top of Jinzhou City, Luke Dehun slept in the city for a few days, but did not encounter Gan Jun's sneak attack.

He stood on the top of the city with dark circles in his eyes, paying close attention to the movements of the troops outside the city.

In a few days, the Gan Army had completed the preliminary preparations for the siege, built heavy artillery positions on the distant hillside, and the trench was almost dug to the city.

This made the Qing soldiers more and more panicked, but Luke Dehun gradually calmed down. He looked at his bastion defense system, the four corners of the main fort and four triangular forts, forming cross-fire power. No matter where the Gan Army attacked from, they would be fired by two to three directions.

In addition, most of the walls are under the ground plane, which reduces the probability of being hit by artillery. The inclined walls can form a jump, greatly reducing the role of the heavy artillery of the Gan Army.

The four triangle castles and the main castle, as well as the inner castle wrapped in the main castle, are as high as the stairs.

This means that when the Gan army rushed to the Triangle Fort, the defenders on the fort can fight with the Gan army in close combat, while the shooters on the main fort can shoot the Gan army in condescendingly on the Triangle Fort. When the Gan army climbed the main fort, the defenders on the inner fort can name the uncovered Gan army.

The Qing army stored a large amount of gunpowder and city-guarding equipment in Jinzhou City. As long as the food is not enough, the city will not fall.

Luke Dehun felt that if he had attacked himself, perhaps even 400,000 people would not be able to defeat Jinzhou.

"Hmph, Gao Huan and I both resisted their heads on their shoulders. I want to see how many people he plans to die and how to capture this bastion!" Lukedehn made his teeth sound and made a heart. If the Qing Dynasty perished, the Aisin Jueluo family would definitely not have a good end.

Don’t think that Gao Huan treats Dorgon and Mandahai preferentially, that’s because the Qing Dynasty is still there. If the Qing Dynasty falls, it will definitely be worse than the dog.

Three miles away from Jinzhou, Du Yinxi led a group of staff members and was carefully observing Jinzhou City with a thousand-mile mirror.

"Record! The frontal observation did not reveal the city gate. The city gate should be behind the Triangle Fort, let Kong Mingqiu confirm it!" Du Yinxi said while using a thousand-mile mirror to observe: "The wall is inclined, but the slope is steep. If you want to climb up, you still need to prepare to climb the ladder!"

Next to Du Yinxi, several soldiers quickly drew drawings and recorded his words on them.

"In addition, there are low walls and trenches outside the fort group, and siege equipment is not reliable. If the Qing army buried mines and sprinkled caltrops, it would be even more troublesome!" As he said that, Du Yinxi put down the Qianli Mile Mile Mile Mile and turned his head and asked, "Have you remembered it?"

"Don't worry, Master Ge, I've recorded it all!" The consultant presented the drawings to Du Yinxi to watch.

Du Yinxi looked at it, and he was still full of pictures and texts. He nodded, "Your Majesty is going to hold a meeting tonight. See if there are any missings. If you have any questions, put Kong Mingqiu and observe clearly!"

"Yes!" Several staff members hurriedly saluted.

On the night of the fifteenth day, the Ganjun camp under the city of Jinzhou was brightly lit, and soldiers outside the camp dug deep trenches overnight. The nearest trenches had reached two hundred steps below the city.

In the central army's tent, Gao Huan gathered with the generals in the tent, lit large wax around it, illuminating the tent like daytime.

At this time, Gao Huan stood in front of the sand table with his hands in his arms and asked, "There is nothing missing?"

Attacking a bastion will inevitably lead to heavy losses, and every mistake in detail may lead to failure in siege.

Therefore, Gao Huan hopes to understand all aspects of Jinzhou's city defense through the sand table so as to formulate a siege plan that is as perfect as possible.

Du Yinxi took the drawings drawn by the scouts these days, looked at the sand table, and nodded, "Don't worry, your majesty, this was made by the participating soldiers according to the proportion of Jinzhou City. The height of each wall and the layout of the city wall, as long as the ministers and others observe and discovered by Kong Mingqiu, are reflected on the sand table."

Knowing oneself and enemy, he will never be defeated in a hundred battles. In order to attack Jinzhou, Du Yinxi led a group of troops to observe Jinzhou with a thousand-mile mirror for many days, and personally boarded the Kongming ball and observed Jinzhou city defense in the sky.

"Well! Since that's the case, let's see how to get this hard bone!" Gao Huan smiled and nodded. Zhou Wei generals looked at the Jinzhou City restored from the sand table, but all their expressions became solemn.

In the late Ming Dynasty, the bulwark entered the Chinese's vision and was called the gun city by Xu Guangqi. The raised wall on the bulwark was called the Wanmen Platform, which means that it can defeat ten thousand enemies.

Gao Huan glanced at the generals and smiled, "Did you think of the battle at Xianxia Pass back then?"

Zhou Fugui said: "Your Majesty is wise. We were blocked by the Zheng family's bastion for several months. Finally, we leaned against Kong Mingqiu to break through the fortress on the mountain."

As he said that, he pointed his finger at the sand table, "And the Zheng family's fortress is obviously much worse than this Jinzhou."

All the generals who participated in the Battle of Xianxia Pass all expressed a deep expression of consent.

Gao Huan waved his hand and laughed loudly: "The battle at Xianxia Pass was difficult to fight back then. The Zheng family built the fortress on the hillside, which restricted my use of artillery, so it was difficult to capture it. Although the defense of Jinzhou City is strong now, it is not impossible to take it down in my opinion. I have artillery on the ground and Kong Ming balls on my head, and more than 400,000 troops. Jinzhou is even a wall of iron, so I will definitely destroy it."

After hearing Gao Huan's words, Yuan Shizhong asked, "How is Your Majesty going to attack? I'll just obey the order."

Gao Huan looked at the sand table and said in a deep voice: "Since the trench has been dug to the city, the mortar cannon can be shot into the fort group. Since that's the case, then retreat the mortar cannon. You can't be anxious to hit this bastion, you must peel off his defense layer by layer."

Gao Huan picked up the wooden stick and pointed to the trenches and low walls outside the basin. "This is the enemy's outer line of defense, and it is also the first line of defense. It is relatively simple. It is to clear all the enemy's periphery under the cover of artillery. This is the first step. By taking this place, soldiers and siege equipment can get close to the fort group."

The generals nodded slightly, and Gao Huan pointed to the Triangle Fort and said, "These four Triangle Forts are located on the front of the four walls, blocking the city gate. If the army directly attacks the city gate, they will be attacked by Triangle Fort and the main fort. Therefore, to attack the main fort, you must first take down Triangle Fort."

Gao Huan knocked the wooden stick on the Triangle Fort, the main Fort and the inner Fort, then glanced at everyone and asked with a smile: "What do you think the three of them look like?"

Each general frowned and observed, Zhou Fugui said, "I look like I hide from a lotus!"

The generals burst into laughter, Yuan Shizhong said: "Your Majesty means that the difference between the three of them is like going up the stairs!"

Gao Huan nodded slightly, "The metaphor of step is OK. In addition to attacking a battalion, in addition to being shot by multiple firepower when attacking, there is another point, that is, his defense is like a ladder, you hit a layer and look up and there is another layer."

Gao Huan paused, and the wooden sticks hit the Triangle Fort. "After the soldiers cleared the outer defense, they withstood the attack of multiple surface firepower. After attacking the Triangle Fort, the enemy troops on the main fort will shoot down the soldiers who climbed the fort wall from a high place. You see, there is no cover on it, and the Triangle Fort is not connected to the main fort. There is also a trench in the middle. The soldiers on the above cannot attack the main fort and have nowhere to hide, so they will become living targets for the enemy."

The generals looked serious, and Zhou Fugui said, "This fortress of the Tartars is much more powerful than the fortress of the Zheng Family Xiu."

"It seems that attacking Triangle Fort is a trap. If you don't attack him, you will directly attack the city gate. The enemy troops of Triangle Fort will attack the soldiers who attacked the city with the main fort." Yuan Shizhong couldn't think of a solution, "Your Majesty, how can you fight this!"

Gao Huan laughed and said, "It's not impossible! The key is the word firepower! When the soldiers attack the Triangle Fort, I will let the mortar team press forward and shoot the main fort. At the same time, I will raise Kongming balls, like the main fort, drop bombs, suppress the main enemy's firepower, cover the soldiers to occupy the Triangle Fort, and build bunkers."

Yuan Shizhong and others understood that they were just using firepower to suppress, "When attacking the main fort, you can suppress the inner fort in the same way!"

Gao Huan nodded: "Not bad!"

At this time, everyone was discussing the specific details. Suddenly, Yang Yan picked up the tent and came in. "Your Majesty, Ning Yuan reported that the Qing army detoured to the flank of Ningyuan and sneaked into the grain transport team!"

Gao Huan frowned when he heard the words. The corridor of western Liaoning was too long. The Qing army detoured to the west, and the supply line of Qian army would definitely be affected.

Hagging the grain road was Haoge's strategy. He used a strong city to block Gao Huan and sent cavalry to harass the grain road, intending to get the Qian army out of food and retreat.

From this point of view, the longer the Battle of Jinzhou is, the more unfavorable it is to the Qian army.

Gao Huan pondered for a moment and had made a decision in his heart. Since the preparations for siege are almost the same, then organize troops to sweep the periphery, clear obstacles, and prepare to siege the city!

"Hmph! Zhou Fugui, you will lead 30,000 people to Ningyuan, and be sure to ensure the safety of food and grass transportation!" Gao Huan shouted loudly, "The other generals have a good rest and are ready to attack Jinzhou tomorrow!"
