Yuguan will also be Shanhaiguan, the first pass in the world in the future.
Yuguan is surrounded by mountains and sea. It is an important pass in the world that is easy to defend but difficult to attack.
Yuguan was built in the third year of Emperor Kaihuang's reign. The expeditions against Goguryeo in the Sui and Tang Dynasties all entered and exited the northeast through Yuguan. When Anlu Mountain controlled Hedong, it also continuously strengthened the defense force of Yuguan.
Yu Chixin pretended to be a businessman and entered and exited Yuguan several times. He sighed to the players around him: "This Yuguan is indeed the most powerful pass in the world. The guard Cai Wenjing is also a veteran of Shi Chaoyi's command. It is really well defended and there are no flaws."
Many players also nodded. The city wall of Yuguan is very wide and has a trebuchet for throwing stone projectiles.
The entire city wall of Yuguan is very thick. Nowadays, it is difficult for players' artillery to destroy the city wall of Yuguan.
The moat that introduces seawater after digging it makes it difficult for players to install explosive packages under the city wall of Yuguan.
Cai Wenjing was very strict in his military management. Merchants entering and leaving Yuguan could only trade in specific markets. After completing the transaction, they had to leave Yuguan and were not allowed to stay overnight in Yuguan.
The entire Yuguan is a military fortress, and it is difficult for players to sneak into Yuguan and destroy it.
Now everyone was frustrated. The key point of the great roundabout strategy was to occupy Pinglu, close the country for development, and then push southward.
If Yuguan cannot be captured, then the conditions for the development of Guanmen will no longer exist.
At this moment, a player stood up and said: "Boss Yuchi, I have a way!"
Yu Chixin raised his head. This was a backbone of the Adventurers Alliance union, his name was Zhuang Hu.
Zhuang Hu is a high-intensity Internet surfer, an avid fan of P Club games, and the editor of a military forum.
Zhuang Hu is also one of the proposers of the Great Detour Strategy, and this strategy has been repeatedly deduced by Zhuang Hu in a magical historical simulation game.
It's just that a strategy game is a game. The game "Feng Yun of the Tang Dynasty" is not a strategy game where soldiers will pop up just by clicking on the map, nor is it a strategy game where soldiers will risk their lives and charge with a click of the mouse, and military goals must be completed until the last person dies.
Here, an army will collapse if it has more than three casualties. Soldiers will mutiny if they are insufficiently supplied. A long-term siege will also reduce the morale of the soldiers.
After leading his troops across the grassland, Zhuang Hu also understood that the great detour strategy was not that easy.
However, Zhuang Hu still gave up. He first asked: "The city wall is tall, there are many defenders, and it is close to the sea. What kind of city do you think this is?"
"Isn't this Yuguan?"
"Zhuang Hu, are you stupid? What nonsense are you talking about?"
"Are you still joking now?"
Zhuang Hu smiled, and after all the players had scolded him, he said: "I'm not talking about Yuguan, I'm talking about Constantinople!"
Wait, Constantinople?
At this time, Yu Chixin also started to think.
Constantinople, the capital of the Roman Empire, was also the most fortified city in Rome.
And even such a city will fall one day, and this is the so-called "Jingluo sheds tears" day.
In 1453, the Ottoman Sultan personally led his troops to besiege the last city in the Eastern Roman Empire.
The Eastern Roman Emperor Constantine XI led the last army of the empire to hold on in Constantinople. At that time, Constantinople was known as the strongest city in the world, "the fortress that never falls."
The location of Constantinople is the same as that of Yuguan, also surrounded by mountains and sea. The Golden Horn in the north is the channel for sea access to Constantinople.
At the beginning, the Ottoman Sultan really had no way to defend the city of Constantinople. The Ottomans had the most advanced firearms in the world at the time, the Urban Cannon, but they still could not blast through the solid city walls of Constantinople.
Unable to capture the enemy for a long time, the Ottoman Sultan changed his offensive strategy.
He bribed Genoese merchants and sneaked into the Golden Horn north of Constantinople through the Galata area controlled by the Genoese, so as to facilitate a land and sea attack.
The Ottoman Sultan mobilized his army and laid a 1.5-kilometer long log taxiway between the Bosporus Strait and the Golden Horn. Then overnight, he towed 80 light sailing ships to the shore of the strait, carrying people, livestock and
The pulley pulled it over the top of the mountain, and then slid down the slope into the Golden Horn. A pontoon bridge was built at the narrowest point of the Golden Horn, and artillery was placed on the bridge.
On May 29, the Ottoman Empire launched a general attack on Constantinople from both land and sea. On one side, it used artillery to destroy fortifications and bombard defensive ships in the Golden Horn. To the west, the Ottoman Sultan commanded tens of thousands of troops to break in from many places.
castle.
The soldiers and civilians of Constantinople fought bloody battles and defended the castle to the death, but in the end they were outnumbered, ran out of ammunition and food, and the castle was finally captured.
This wonderful offensive and defensive battle is the most exciting battle of classical city defense after the emergence of artillery and ships.
The level of firearms in the Ottoman Empire at that time was similar to the level in Longyou today.
Zhuang Hu said to Yu Chixin: "If we attack head-on, we will definitely pay a huge price. If we fail to attack by force, and Fan Yang's Shi Chaoyi comes to rescue, it will be even harder to fight."
Yu Chixin nodded. Although there were not many guards at Yuguan, Shi Chaoyi, who had annexed Fan Yang, was not far from Yuguan. He could support Yuguan at any time.
Zhuang Hu said: "I have observed over the past few days that the city defenses on the side of Yuguan near the sea are not strong. The designers of Yuguan at that time never thought that the northern barbarians would launch an attack from the sea."
"We can imitate the tactics used by the Ottoman Sultan to capture Constantinople, bombard it from the sea with ships, and besiege Yuguan by land and water!"
Fight from the sea?
Yu Chixin looked at the map and realized that Zhuang Hu's suggestion was actually feasible.
Like Constantinople, the northeast corner of Yuguan is close to the sea, and the city wall on the sea is not as strong as the front.
If we can destroy the city wall from the sea and cooperate with the frontal attack, we should take Yuguan in one fell swoop!
However, some players soon stood up and objected:
"The waters near Yuguan are full of reefs and are not suitable for navigation by large ships at all!"
Zhuang Hu said: "Why do we need big ships? We only need ships that can install artillery and transport assault soldiers at sea. Ordinary transport merchant ships that sail offshore will be enough."
Yu Chixin thought about it and concluded that there was indeed nothing wrong with Zhuang Hu's plan. The sea attack could catch the defenders in Yu Pass by surprise.
"But now that we start building transport ships, will the grand detour strategy be delayed again?"
However, Zhuang Hu was also a little impatient. He had already thought of a countermeasure and said:
"Isn't the boat ready-made?"
off the shelf?
Zhuang Hu said: "Actually, the ships that transport troops and the ships that transport cargo are the same. Aren't they just that the warehouses are a little bigger? Isn't there one readily available in the Northeast?"
off the shelf?
Soon Yuchixin understood what Zhuang Hu meant. If anyone in Northeast Asia can produce so many ships at once, it must be Bohai State.
The Bohai State was founded on maritime trade, and transport ships are their foundation. They must have enough transport ships.
As long as the Bohai State is willing to ship, it only needs to slightly modify the cargo ship to convert it into a troop transport ship.
Even if explosives can be installed on the ship, chaos can be created from the sea to cover the landing of the transport ship.
You must know that in this era, although there were coordinated battles on land and water, the precedent of landing operations from the sea was still very rare.
Yu Chixin quickly made a decision. He said to everyone: "It seems that we have to rely on Mr. Fang for this matter. I will send a message to Mr. Fang and ask him to think of a way to borrow it from Bohai Country."
Some transport ships are coming."
After receiving the news, Fang Guoshou smiled bitterly and borrowed a boat from the Bohai State. This was not an easy task.
However, for the purpose of the great detour strategy, Fang Guoshou immediately set off for Bohai Country.
While the players of the Great Roundabout Strategy were planning Yuguan, Zhang Duanyang, who had just captured Qingzhou, was looking at the coastline of Qingzhou. Qingzhou is close to the Bohai Sea, which is the current generation of Weifang, Shandong.
Standing on the beach, listening to the sound of waves hitting the beach, Zhang Duanyang felt relaxed and happy.
Nan Jiyun, who was walking with Zhang Duanyang, was a little restless. He walked on the beach and said: "Brother Zhang, we have completed the military order and defeated the Qingzhou bandits. Shouldn't we return to Luoyang at this time and guard Luoyang with Zhang Liushou?"
Although Nan Jiyun was a fierce general in the world, he was not proficient in strategy.
During this period of fighting, it was Zhang Duanyang who made the plans, and indeed the losses were much smaller than Nan Jiyun's own attack.
Gradually, Nan Jiyun began to rely on Zhang Duanyang to make decisions.
At this time, Nan Jiyun was eager to return home, but Zhang Duanyang looked at Bohai and said:
"General Nan, do you think we can get on the boat and cross the sea from here to the east of the river?"
Nan Jiyun was stunned for a moment, a little confused by Zhang Duanyang's question, and he said:
"Why attack Hedong? Didn't Shi Siming of Hedong surrender to the Tang Dynasty?"
Zhang Duanyang said: "An Qingxu's turmoil in the northern part of Henan Province is just a fight between trapped beasts. The northern part of Henan Province is small and the people are weak, so there is no way he can support him for a long war."
"Marshal Guo and Zhang Liushou are both famous generals in the world. As long as they build a defense line in Luoyang and consume An Qingxu's food and grass, An Qingxu will soon be killed."
Zhang Duanyang pointed at the Bohai Sea, trying to see the opposite coastline through the Bohai Bay.
"Hedong is my greatest concern in the Tang Dynasty!"
Although Nan Jiyun didn't understand strategy, he understood what Zhang Duanyang meant. He asked, "Brother Zhang, are you saying there is another rebellion in Hedong?"
Zhang Duanyang nodded and said: "Shi Jia's father and son are ambitious. Back then, he could follow An Lushan and betray the Tang Dynasty, and he could betray An Qingxu and surrender to the Tang Dynasty. Now it is not strange to betray the Tang Dynasty."
Nan Jiyun said anxiously: "In this case, shouldn't we return to Luoyang immediately? If Shi Siming also joins An Qingxu and attacks Luoyang together, how will Zhang Liubei be defended?"
Zhang Duanyang shook his head and said: "Luoyang is one of the two capitals of the imperial court, so it will naturally recruit troops for defense. We can play a greater role by staying in Qingzhou."
"What does it do?"
Zhang Duanyang pointed to the sea mysteriously and showed a faint smile.
