Baogukou is at the southern end of Baoxie Ancient Road, and adheres to the most important passages between Guanzhong and Hanzhong. As long as you occupy Baogukou, it will be difficult for the main force of the Yuan army in Guanzhong to support Hanzhong. It is only possible to detour and change to Chencang Road, which is too late.

Moreover, it can also attract the Yuan army in Hanzhong to divide its troops to attack, making it easier for the Tang army to occupy the battle of Hanzhong.

This is a strategy planned by the secret agents of the Tang Kingdom.

"Send the order and start and attack Baogukou!" Tang Mu issued a military order, and ten thousand rebels whose combat power and armor were improved immediately went out in full swing.

The book friends used the small book Pavilion before has already been hung up, but now they are basically using it.

The spies had known for a long time that since Baogukou was the rear of Hanzhong, there were very few Yuan troops stationed, with less than 3,000 people. As long as they were surprised, they would be able to succeed soon.

Even the route of sneak attacks, the spies had already chosen it.

They prepared for this day for a long time.

Soon, ten thousand rebels set out from the back mountain of Xiqueling, and followed a narrow valley, under the cover of the forest, quietly heading towards the Baogukou dozens of miles away.

The Yuan army never expected that the "bandit" who could not hide from the depths of the Qinling Mountains for more than half a year would become a knife of the Tang army, and they dared to take the initiative to attack Baogukou.

However, although this mountain road is hidden enough, it is very rugged and difficult to travel. It is not possible to reach this seventy or eighty-mile mountain road, ten thousand people may not be able to reach it in two days.

After so long, the Yuan army in Guanzhong is likely to come to support.

…………

At this time, the Tang army led by Li Luo had already passed the most steepest Jiange Road and entered the Jinniu Road. The Zhaohua Mountain City (Jiameng Pass) among the mountains and ridges was already far away.

The Tang army had 20,000 firearms and the logistics transportation pressure was very high. It took seven days to walk the two hundred miles of mountain road.

"Your Majesty, Zhaohua (Jiameng Pass) is ahead. The Yuan army has 20,000 troops. Jiameng Pass is easy to defend but difficult to attack. You will ask Your Majesty to attack me at that time. It is not advisable to take risks easily." Zhu Han, the governor of Yizhou who was following the expedition, said.

The former garrison of Lingxiao City, and the current Sima Yi Shiying of Yizhou, also said: "Your Majesty, Fuling Hou (Zhu Han) is right. He will attack the city in a dangerous place, and the general will not take it, let alone Your Majesty is the Emperor of the Tang Dynasty."

Li Luo nodded, "Zhu Han, then you will be responsible for the siege."

"Abide by the order." Zhu Han took the order, "Please retreat into the rear army."

Although Jiameng Pass is difficult to fight, and Hanzhong Yuan army marshal Denur himself was in charge, Li Luo still has a clear idea.

Because Qingshan is Denur'er's aide.

Qingshan is Cui Xiuning's third group of students, and he is good at learning Mongolian language. He has been involved in Hanzhong and has been working as an aide to Denur for three years, and is trusted by Denur.

Why does Denur want to use a Han man as an aide?

Because the 50,000 yuan army in Hanzhong was mainly Han army (Kerqin Army), and the Mongolian Semu cavalry was only 12,000, so Denur needed a fluent Han Chinese aide to coordinate the tens of thousands of Kerqin Army under his command.

Hanzhong is also a basin, surrounded by mountains, which is very dangerous. The first pass to guard the route to Hanzhong north is Zhaohua Mountain City (Jiameng Pass), the second pass is Ningqiang Pass, and the third pass is Yangping Pass (in Mian County).

When Liu Bei attacked Hanzhong, he occupied Dingjun Mountain from the Micang Road, passed the Han River and headed north to Yangping Pass, and entered the hinterland of Hanzhong. However, the Micang Road had long been abandoned and could not march, so the Tang army could only walk on the Jinniu Road. When the Qin army attacked Bashu, he also walked on the Jinniu Road.

Only by opening these three passes on the Jinniu Road can we enter the hinterland of Hanzhong. Therefore, the Yuan army in Hanzhong mainly deployed defenses at these three passes. The most important Jiameng Pass was guarded by Marshal Denur himself, and the troops reached 20,000.

Li Luo looked at Jiameng Pass, but saw dangerous rocks and cliffs, trees and only a mountain road that was more than a wide stairs, circling up to Guancheng, which was really dangerous, not under the Jianmen. He could hear the roar of the Jialing River not far away.

Then he said to the generals: "Jiameng Pass, where Emperor Zhaolie stationed his troops back then, and where Zhang Fei fought against Ma Chao. Within three days, I will enter this pass and hang Zhaolie's ruins."

Zhu nodded: "Please rest assured by your Majesty! I will definitely capture this pass within three days!"

In fact, even if there are artillery, it is undoubtedly a dream to conquer Jiameng Pass under such terrain. Since ancient times, it is definitely not possible to attack Jiameng Pass by only narrow roads, and you must also occupy the mountains on the right side of the city and shoot arrows from a high place.

Moreover, the Tang army had been trekking on the Taurus Road for several days and had been exhausted, and could not attack the city within at least one day.

But Zhu Han already knew that there was an internal support in the city of Guan. Your Majesty knew the military strategy well. If he was not sure, he would not say that he would go to Guan to pay tribute to Liu Bei's remains within three days.

Zhu Han was indeed a general. He observed the nearby mountains and chose a hillside where he could barely carry artillery artillery, and ordered the ten-kilogram cannon to be transported to the top of the mountain.

At the same time, Zhu Han ordered the front team to pass on the back team, so that the gentry in front would climb to the mountains on both sides and free up the road for the soldiers behind.

Although the Taurus Road is relatively wide, it is only more than one meter wide. Seventy thousand Tang army supplies and horses were densely packed with long snake formations dozens of miles long, and the troops could not be concentrated on the front line.

Zhu Han did this, and soon the mountains on both sides of the road ahead were covered with dense Tang troops, making the troops in front more and more.

Most of the slopes of the mountains are very steep, but infantry can still climb up, and after climbing up, they can barely use trees as a support so as not to roll down.

By dusk in the afternoon, more than 10,000 people had gathered on both sides of the mountains. There were also more than a dozen cannons transported to the top of the mountain through the not-so-steep hillside.

In order to transport these dozen cannons to the top of the mountain, everyone was exhausted. Zhu Han even dug a small mountain road temporarily. It took him half a day to pull people up and get them up. It was really painful.

The top of this mountain is less than three miles away from Jiameng Pass, and the range of ten kilograms of cannons is just enough. Bombing the Jiameng Pass from the top of the mountain is definitely a nightmare for the Yuan army defenders.

The Yuan army several miles away had seen such a big noise from the Tang army. However, it was difficult for them to go out of the city to attack the Tang army.

If they leave the city, they can only set up a long snake formation. How can they fight?

At this time, the Yuan army on Guancheng had been on strict condition. The front wall and the right wall were covered with crossbows, stone throwers and firearms.

The Yuan army camp in the city is located not far from the city gate.

Military discussions are being held in the Yuan army's tent.

Although most of the families in a group of thousands of households were Han people, they all had hair and braids, and even their names were changed to Hu's name.

Of course, most Chinese people will still not understand the complex Mongolian language very much.

Marshal Denur, who lived and sat in the city, said coldly to the generals: "The time has come to attack the rebels and test your loyalty to the Yuan Dynasty. I, Denur, only one word, guard this Guancheng, and protect your wealth. If Guancheng is lost, you will be the shepherds who have lost the pastures and become cow dung that is worthless to a sheep."

A young man with the same hair and braided hair immediately translated the words of Denur. However, if someone proficient in Mongolian and Chinese were present, he could tell that there were some problems with his translation.

This is how he translated:

"If the rebels come to attack, you know that you Han people are not loyal to Da Yuanzhong. I warn you that if you want to survive, please be careful. If Guancheng is lost, you will be a waste who is inferior to cow shit! Do you still want to survive?"

When the Han generals heard this, they were immediately unhappy and dared not refute it.

The Mongolian generals didn’t understand Chinese language very well, so how could they hear it?

This young man who served as a translator came to Qingshan, a spy next to Denur three years ago.

He was sent to Hanzhong by Cui Xiuning himself, which shows that Li Luo's intention to plot against Hanzhong was brewing a long time ago.

Although all members of the Kerqin Army (Han Army) were Mongolianized, Nur still looked down on Han generals from the bottom of his bones and did not dare to trust Han generals completely. It was normal for him to speak, but it was absolutely impossible for him to not give any face as Qingshan translated.

People need face, and traitors don’t want any face, right? Especially they care very much about the face given by their master.

The master's words are too ugly, and their hearts... will also be hurt!

Of course, Qingshan would never think that a few insulting words could make the traitors rebel against Da Naoer, which was really difficult for them.

After the training, Denur got to the point and assigned a defensive task.

After Qingshan finished translating, the generals took the order to issue the account.

Then Qingshan whispered to Denor, "Ma Si Tie (master), I suggest that I should send my master and two deputy commanders to the army of the Han army generals as the military supervisor? I saw the dragon flag of the rebels, and it was probably because of the pseudo-Tang Li Luo who came in person. I was worried that the Keerqin army might have a second thought."

Denur likes Qingshan, a loyal, smart and capable Han man, very much. Qingshan has been following his wishes for three years, thinking about himself everywhere, and is worthy of his trust.

But at this moment, Denur still smiled and said, "You dog slave is also a Han, why do you say this instead? Wouldn't you have a second intention to surrender to Li Luo?"

Qingshan smiled bitterly and said, "I am loyal to Ma Si Tie (master). Ma Si Tie is the god of slaves. Why is the slave like them? Besides, Jun Cai is just a small staff member, not a general who leads troops. Even if he surrenders, the pseudo-Tang will not reuse it."

"And." Qingshan gritted his teeth, "The slave family was confiscated by the pseudo-Tang family. The slave hated them to the core. Even if they died, they would not surrender to their enemies."

Denur laughed and pointed at Qingshan and said, "What you said makes sense. However, there are already Mongolian military supervisors in the Han army. There are not many Mongolian Seminar warriors in this Guancheng army, and most of them are personal soldiers of Mongolian generals. It is not appropriate to send them to the Han army."

Although there were many Mongolian soldiers in the Yuan army in Hanzhong, they were all cavalry. Mongolian soldiers would not be infantry guarding the city, which was too wasteful. Therefore, the Mongolian cavalry under Denur were stationed in the hinterland of Hanzhong to guard the mountain city. The cavalry guarding the mountain city was basically useless, so they were not stationed here.

When it comes to defending the city, the Han army's infantry is much stronger than the Mongolian cavalry.

This makes it very few Mongolian soldiers in Jiameng Pass. This is also the reason why Denur is worried and wants to guard the front line in person.

Qingshan said: "Slaves are all thinking about their masters. Although there are military supervisors at the hundreds of households in the Keerqin army, in extraordinary times, if someone rebels, they will not be able to suppress the military supervisors at all."

After the Han army was reorganized into the Kerchin Army and the Zhelim Army, even the Hundred Houses level had a Mongolian military supervisor. However, the Kerchin Army with a team of 10,000 people had only more than one hundred men.

So if there is a team of ten thousand people who are determined to rebel, just these more than a hundred Mongolian military supervisors, they can't even control the Han generals. The Han generals also have personal soldiers.

When Denur thought of this level, he felt that Qingshan was indeed loyal and thoughtful.

He felt that Li Luo came to attack the city in person, and the Han general was indeed not reliable. Instead of letting his personal soldiers protect him, it would be better to send him to watch the Han generals.

As long as they suppress the personal soldiers of the Han generals, it will be difficult for them to rebel.

In fact, Denur really underestimated the loyalty of the traitors. Of course, it was not his fault. If a Mongolian general was not in his power, he would not be completely relieved if most of his subordinates were Han people.

So, the more suspicious he was, the more he was, the more he was, he immediately gave an order.

In the name of assisting in defending the city, he sent himself and two deputy commanders, 300 Goshik (personal soldiers, namely Manchu Goshik), to join two 10,000 teams of Kerchin Army.

In this way, the total number of personal soldiers of Denur and the two deputy commanders was less than twenty.

As for their own safety...joke, they are in their own army, as long as the Han will not be able to rebel, are they still worried about safety?

When the Han generals saw that more than 300 Mongolian soldiers had come to monitor them and said that they would help defend the city, they were completely in a bad mood.

Isn’t this obvious trust?

We are the Kerchin army who shaved their hair and changed their clothes. Why can’t we trust us? Should we take out our hearts and let Dayuan see if our hearts are loyal or treacherous, black or white?

Suspicion of loyal ministers!

However, although they were very dissatisfied, they could only complain inwardly and did not dare to object at all.

Not only did I dare not object, but I also became more cautious and worried that I would be misunderstood if I didn't work hard.

To be fair, the dispatch of hundreds of Goshkes to the Naur did greatly increase the control of the Han army. The effect was still very obvious.

That night, there was nothing wrong. The Tang army did not attack because of the renovation.

It was not until the afternoon of the next day that Zhu Han asked Li Luo whether to launch a bombardment to bombard Jiameng Pass.

Li Luo tried hard to climb up the shortest mountain and looked at Jiameng Pass not far away. He wondered whether Qingshan and others could play a role.

Qingshan was carefully selected by Cui Xiuning and arranged it himself, and it is impossible for him to have nothing to do.

However, when a large army fights, we cannot put our hopes on the spies. Without spies, we cannot fight?

"Let's start the war." Li Luo gave the order.

Soon, the Tang army artillery on the top of the nearby mountain roared. However, the infantry did not take the initiative. Zhu Han's tactic was to use artillery to bombard the city walls, kill and injure the Yuan army, and attack the morale of the Yuan army, and promote changes in the city.

"Boom boom! Boom boom!"

A loud thunder echoed among the mountains and ridges. The cannonballs as big as bowls and the grape shells as big as eggs, and the like of heavenly punishment rushed towards the city of Jiameng Pass. The Yuan army suddenly screamed and flesh flew everywhere. The bricks and stones on the city were immediately shattered by bombardment.

The rebel artillery was too fierce and was hit too far.

"Don't be afraid! Don't be afraid! The rebel artillery will not collapse in the city!" The generals of the traitor army shouted. Although the traitor soldiers were shocked by the power of the Tang army's artillery, they quickly calmed down and organized people to lift the dead and injured.

That's right, such a strong and thick city wall cannot be knocked down even with the Tang army's artillery.

The city wall is more than one meter thick, and even the artillery of later generations is difficult to blow away in just a few shots.

"Prepare" the artillery warrior waved the Tang sword, "Let it go!"

"Boom boom boom!" Another earth-shaking roar, the second round of shells baptized the city wall again. Two rounds of shooting brought hundreds of casualties of the Yuan army.

The traitors roared and scolded, while replacing the casualties, and using shields to protect them, hiding under the city.

Their long-range weapons could not attack the Tang army, so they could only be beaten passively. However, they did this to minimize the killing of the Tang army's artillery.

At this time, we can see that the combat quality and will of the Kerchin Army were indeed much better than the Southern Traitor Army. It was not that they were braver, but that they were more stubborn and more loyal to the Yuan court.

The Tang army bombarded more than ten consecutive rounds, and the Yuan army suffered more than 1,000 casualties, but they still stood on the top of the city, constantly replacing the dead and injured, and constantly setting up wooden boards to enhance protection.

The city walls were also bombarded with incompleteness, but the walls were still strong.

However, the morale of the Yuan army continued to decline, and finally the morale of the army began to rise.

More than a thousand casualties seemed to be not much, but it seemed to consume a lot of ammunition from the Tang army. But the problem is that even a single Tang army did not kill or hurt!

Can't defeat the Tang army.

A thousand to zero battle loss!

How can I fight this battle? If anyone else is it, morale will plummet.

The generals of the traitor army cheered their subordinates one after another, but the rebels had limited ammunition and could not keep firing like this. As long as they persist, they would be able to defend them.

At dusk, Zhu Han ordered the storm to stop the artillery attack. The Yuan army, whose morale was turbulent, breathed a sigh of relief. But they did not dare to be careless and did not dare to leave the city.

The autumn night soon came.

Li Luo stood on the top of the mountain and looked at Guancheng with lights on, and couldn't help feeling a little sad.

He didn't know how many Yuan army he killed and injured, probably only a thousand. After all, the Yuan army was protected by the city walls, not on the plains.

Guancheng, a military key area, is not an ordinary city, and the strength of the city wall is much higher. He knew that later Japanese army's planes and cannons bombed Tongguan, but they failed to capture it.

Today, such a small bombardment cost several thousand kilograms of gunpowder!

If he continues to fight like this, his gunpowder will be exhausted until Guanzhong is gone.

It seems that tomorrow cannot be wasted. Archers should be sent to climb the mountain on the right and shoot from a high place.

In fact, since ancient times, what the defenders of Jiameng Pass fear most is that the enemy climbed the mountain on the right side of Guancheng and attacked Guancheng from the side. The enemy's troops on the front could not be expanded, but they were not afraid.

So, why didn’t the Yuan army seize the mountain on the right side of Guancheng in advance? Because it is easier for the enemy to attack mountains than attack cities, they have fewer troops, so staying in the city is safer.

At this time, the subsequent Tang army had not arrived yet. The hillsides on both sides were covered with Tang army soldiers, but there were only 30,000 to 40,000 people.

The Tang army on the tail of the snake at the end was at least ten miles away.

Li Luo couldn't help but smile bitterly. This kind of terrain war is really hard to fight.

All the way, there were long snake formations, and there were many dangerous barriers. It was too difficult to attack Guanzhong.
Chapter completed!
