There are two strategic routes from Guan Nei to Guanzhong. One is the Jingshui Road, which enters Guanzhong from Yuanzhou and Jingzhou. It was through this road that the Jingyuan Army entered Chang'an and created the Jingyuan Mutiny that almost destroyed the Tang Dynasty.
The other strategic passage is called Luoshui Road. It runs along Luoshui from Yanzhou, through Yanzhou, Fangzhou, and into Tongzhou, Guanzhong. Two reinforcements sent by Zhu Si went north from Jingshui Road and Luoshui Road respectively.
The Luoshui Road is the strategic passage for the Guo and Song armies to go south to Guanzhong. This passage is much easier to walk than the Jingshui Road, but it also has two important passes, both located in Yanzhou. One is the Yanbeiguan Pass in Fulu County.
It is called Foguan, and one is Luonan Pass in the south, which is called Luoguan for short. The two passes are about a hundred miles apart and are called Fuluo Road. It is a straight Qin Road built in the mountains. There are two passes along the way.
Generally, business travelers can arrange food and accommodation at the inn, but if the army is trapped between these two passes, it will be extremely dangerous.
But once these two passes are captured, the Fangzhou Road and Tongzhou Road below will be a smooth road, and you can directly enter Guanzhong. Therefore, these two passes are crucial, especially Luoguan in the south, which can be said to be the last way to enter Guanzhong.
A gate.
There are about 5,000 troops stationed all year round in Fuzhou, including 2,000 troops stationed at Fuguan in the north and 3,000 troops stationed at Luoguan in the south.
In order to prevent Yanzhou from being lost, Zhu Si sent Zuowuwei General Liang Tingfen to lead an army of 30,000 to the north quickly. Following Liang Tingfen, Zhu Si's deputy military adviser Wang Yu also went north.
Thirty thousand troops arrived in Fulu County. At this time, news came from the north that Guo Song personally led an army of 30,000 troops to capture Suizhou and was heading towards Yanzhou.
This news made Liang Tingfen very nervous, and she quickly summoned Wang Yu for discussion.
Wang Yu is about fifty years old, very thin and dry, but he is very cunning and good at using strange strategies. Liang Tingfen is brave in battle, but has a simple mind, so Zhu Si wants Wang Yu to follow him and be responsible for planning the battle plan.
Wang Yu looked at the map and shook his head and said: "There is at least 150 miles from Fulu County to Fushi County. We will definitely not be able to catch up."
Liang Tingfen snorted heavily and said: "Then strictly guard the two passes and block the Hexi Army from outside."
Wang Yu looked at the map and said slowly: "General Liang, don't you think this is an opportunity?"
"Chance?"
Liang Tingfen was stunned, "I don't understand, what opportunities are there?"
Wang Yu pointed to Luoguan and Panguan Road on the map: "Suppose Guo Song and his 30,000 troops were trapped in Pangluo Road, with no way to the sky and no way to the earth. As soon as Guo Song died, his foundation would fall apart.
The greatest threat to my lord has been eliminated, General Liang, what a great achievement is this?"
Liang Tingfen felt a rush of blood rush to her head, and she struck with her fist: "Fuck you, what should the military advisor say we should do?"
Wang Yu pondered for a while and said: "First of all, we must strengthen the defense of Luoguan, and station at least ten thousand troops so that Guo and Song's army cannot attack Luoguan. Secondly, we disappear, and when the main force of Guo and Song enters the Luo Pass, we will fight back to capture Luoguan.
, it’s done, but it’s a little risky. Once we divide 10,000 troops in Luoguan, we will only have 20,000 troops left in our hands. I am afraid that we will not be able to match the army of Guo and Song. I am mainly worried about this."
Liang Tingfen wanted to capture or kill Guo Song, and he was eager to achieve success. He immediately said: "Wealth can be found in danger. As long as Guo Song can be killed, the risk is worth it!"
Wang Yu nodded, "That's alright! The worst is if he sees through it and refuses to be fooled, we can just give up on this strategy and there will be no loss."
The two discussed some more details before finalizing the final plan...
Guo Song had been planning to attack Guan Nei for half a year. How could he not know the dangers of Polo Road? He had been paying close attention to the enemy's movements.
That morning, he received news from scouts that 20,000 enemy troops had left Fulu County at night and secretly headed northwest. However, there were not many enemy troops in Luguan.
Yao Jin looked at the map and said with a smile: "Your Majesty, the enemy is asking you to put yourself in a urn!"
Guo Song sneered and said: "They have a good idea. They trapped me to death in Puluo Road and they will have a huge credit. I might as well help them and see if they have the ability to take this credit!"
Yao Jin understood what Guo Song was thinking. He smiled and said: "My lord, you don't have to take risks. I will go in under my lord's name and seize Luoguan. My lord will just hold the gate for me."
Guo Song pondered for a moment, that's okay, it's actually the same thing, and he smiled and said: "There is actually a biggest variable in this, which they could not have imagined in their wildest dreams."
"Lord, you mean Liang Wu's army?"
Guo Song nodded, "If they knew that the 30,000-strong army was about to attack, they would not dare to take this step even if they were killed."
.........
Guo Song left 5,000 troops to guard Fushi County. He immediately led 25,000 troops southward and attacked Luguan in a mighty manner. Two days later, the army arrived at Fulu County.
However, the army of Guo and Song did not stop in Fulu County, but went directly to Fuguan.
Fuguan is located about ten miles south of Pinglu County. It was built at a high point at the mouth of the valley. The city is tall and dangerous, easy to defend and difficult to attack. When the Guo and Song army arrived at Fuguan, the two thousand defenders withdrew without fighting and quickly moved towards the south.
Luoguan was evacuated.
The Hexi army captured Fuguan without any bloodshed. Guo Song personally led an army of 10,000 to guard Fuguan, while Yao Jin led an army of 15,000 to attack Luoguan, a hundred miles away.
The 20,000 troops led by Liang Tingfen and Wang Yu were hiding in Jincheng County, eighty miles to the northwest. According to Wang Yu's strategy, if Guo and Song's army refused to fall into the trap, they would have to withdraw to Fuguan.
Of course, there is another possibility. Guo and Song's army cannot capture Luoguan, and they cannot recapture Fuguan, but this problem is not big. Guo and Song's army has no logistical supplies and cannot hold on for long. If they cannot capture Luoguan within five days,
, they could only retreat north, return to Yanzhou, and finally return to the starting point.
The key here is that Luoguan cannot be lost. Wang Yu is still sure of this. Luoguan is a deep canyon, and the army is defending against the mountains. It is difficult to break through even a thousand defenders. There is no need to have 13,000 defenders there.
Unless the defenders take the initiative to retreat, the Hexi Army will basically be unable to break through Luoguan.
That night, Liang Tingfen received an urgent report from spies that Guo Song personally led an army of more than 20,000 people into Polo Road.
Liang Tingfen was overjoyed. This was simply a miracle from heaven! He immediately led an army of 20,000 people to kill Fuguan overnight...
Fuguan is a city covering an area of about 100 acres. The Dapeng Mountain stretches for hundreds of miles, dividing the north from the south. The Luoshui River flows through a deep gorge, and Fuguan is built high on the mountainside next to the canyon.
, with towering mountains on one side and deep canyons on the other, there is only a mountain road about ten feet wide that can go south. This mountain road is also a straight Qin Road, and the ground is extremely flat and solid.
The mountain road winds southward between the mountains, about a hundred miles long, and the southernmost exit is Luoguan.
Fuguan is located at a high place. When coming from the north, you have to climb a gentle slope, which makes the pass condescending. The city wall is tall and strong. The city gate is usually closed and the suspension bridge is pulled up, making it easy to defend but difficult to attack.
On the day Guo Song entered Fuguan, the soldiers discovered the enemy's moves. Zhu Si's army actually dug a hole on the loess cliff east of Guancheng. The hole was dozens of feet long. You could follow this hole directly to the pass.
On the city, the exit is only blocked by a stone tablet recording achievements. If the stone tablet opens a gap, you can get out.
This is also a characteristic of the Loess Plateau. It is not a stone mountain, but a loess mountain thousands of meters thick. The loess is very sticky and is very suitable for digging holes. Most of the people here live in cave dwellings.
The stone tablet had been removed, and the entrance to the hole was blocked by some vines. The soldiers removed the vines, revealing a dark round hole with a diameter of about four feet.
"Your Majesty, why don't you put some iron fire mines, wait until the enemy troops are crawling inside, blow up the cave, and bury them all!" A soldier suggested.
Guo Song shook his head, "Don't go to so much trouble, let them dig in and arrest them one by one. I just want to ask for some confessions!"
........
In the evening of the next day, 20,000 Zhu Si's army arrived in Fulu County. At this time, the peripheral spies of the Hexi Army immediately sent an alarm to Luguan.
At two o'clock, people had fallen into a deep sleep, and there were only sporadic patrols patrolling Guancheng. Liang Tingfen led an army of 20,000 people and quietly approached Guancheng.
An army of 500 people also arrived at the foot of the eastern mountain. They moved away the boulders covering the entrance of the cave. The white ash at the entrance of the cave was still there, with no sign of being touched, indicating that the Hexi Army did not discover this secret passage.
With knives in their mouths, the soldiers crawled into the cave one by one, crawled out more than thirty feet, and arrived at the top of the city. The leading soldier pushed the stone tablet open a crack, and when he saw no one outside, he got out.
Before he could straighten up, someone covered his mouth, and two soldiers controlled him and dragged him away.
But the people in the cave didn't know that as soon as they came out, one was arrested. More than 20 people were arrested in a row. The people behind finally realized that something was wrong. Someone in the cave shouted: "You have been tricked, retreat quickly!"
At this time, a dark iron lump the size of a winter melon rolled into the cave, with white smoke rising from it. A red light burst out, and the iron fire thunder exploded violently in the cave. Dozens of people were killed on the spot.
He died, and the cave collapsed immediately. More than a hundred people had no time to exit, and they were all buried alive in the collapsed cave.
