In Dangyin City, under the corridor of the hall, Chen Mu was sitting cross-legged on the mat. In front of him was a blazing stove. The cold wind blew through the bamboo curtains and blew into the house. It was even colder inside than outside.
At this time, thousands of miles away, the battle between the Qingzhou Army and the Jizhou Army was heating up. The two sides were fighting to the death, with casualties reaching tens of thousands.
It's just that the information couldn't be transmitted quickly. Of course Chen Mu didn't know that Liu Bei and Yuan Shao had fallen into a life-or-death situation.
But he did know one thing, that is, Yuan Jun occupied Yixian County half a month ago and rebuilt camps and strongholds in Yixian County. After being attacked by Zhang Liao, the offensive was suspended due to heavy rain and road closures.
Based on this information, he deduced that Yuan Jun would never give up and would definitely take action against Qingzhou within a short period of time, and the time would definitely be within the next few days.
The reason why he was able to calculate it is very simple. Because November in the Han Dynasty is now the twelfth month of the solar calendar in later generations.
This is the time when the weather is the most bitter and cold. It is the twelfth lunar month in the middle of winter, the snow is falling heavily, and the Jiuhe and lakes have not melted yet.
When December, which is January in the Gregorian calendar in later generations, is approaching the beginning of spring, the temperature will warm up. By then, the ice and snow in Jiuhe will melt, and there may not be such a good opportunity.
So if his guess is correct, Yuan Jun must have made some moves in the past few days. On Chen Mu's side, in order to support Liu Bei, he must also speed up his progress and achieve some results on the western battlefield. It is best to threaten Yecheng.
Let Jizhou be shaken and unable to attack Qingzhou.
At this time, Zhu Jun was sitting in Dangyin City. Zhu Jun was wearing a large cotton-padded jacket and sat opposite Chen Mu. When he saw Chen Mu lowering his head and thinking deeply, Zhu Jun poured himself a glass of wine and said with a chuckle: "My son."
Come on, what are you thinking about?"
"I'm thinking that Jizhou must have launched an offensive against Qingzhou now. If my calculations are correct, the Jizhou army has probably reached Pingyuan City... Of course, it may also be blocked by the river."
Chen Mu woke up from Zhu Jun's words. He seemed to realize that it was rude to be distracted, so he adjusted his sitting posture, picked up the teacup and took a sip, and said softly: "Lieutenant, it has rained these days, so the water should have risen."
Quite a few, the current dam should be almost collapsed."
"Well, I'll report from the front, it's almost done."
Zhu Jun said: "Originally, I wanted to order the dam to be opened immediately, but Yun Chang was trapped by heavy rain and could not retreat back, so I delayed the order."
Chen Mu glanced at the drizzle outside, nodded and said, "It should be sunny in the past two days."
"Are you going to the dam?"
Zhu Jun asked.
"I have to go there and send someone to urge my second brother. It's best to take action tonight. We can't wait any longer."
"I understand, leave this matter to me. I will send someone to report it later."
"Then I'll go to the outlet of the ditch and take a look."
Chen Mu stood up. It was still raining outside, but the planning for more than two months was today, and he didn't have to worry about it. He still had to go there in the rain.
In fact, more than a month ago, the ditch between Dangshui and Huanshui had been dug, and the two rivers were successfully connected. At the same time, construction of a dam began on the upper reaches of Huanshui to intercept the water flow.
The water storage speed was very slow at first, because this year's climate was abnormal, the summer was very hot, and the drought was severe. Except for the Yangtze and Yellow Rivers, which are supported by snow-capped mountains, the Huanshui and Dangshui both originate from groundwater in the Taihang Mountains.
The flow rate is relatively fixed, and without the support of snowy mountains and water, the downstream areas will be depleted in the event of drought.
In winter, thanks to the structure of the Luoyang Basin, there are often continuous rains in winter, and the water flow in the upper reaches surges. It should be a happy thing, so that the floodgates can be opened directly to release the flood, but it turns out that the water has only been stored for a few days.
, suddenly it started to snow again, freezing the river surface.
Regarding this capricious weather, even Chen Mu, who is so smart that he is almost a demon, can do nothing about it. This is because the Little Ice Age was like this. Severe droughts and floods occurred one after another in the summer, and the winter was extremely cold. Not to mention the north, even Jiaozhou
It can give you a heavy snowfall.
The heavy snow has been falling for another half a month. It finally stopped a few days ago, and it started to rain again. Not only did Chen Mu's ditch digging project suffer, but even Guan Yu's side was closed due to rain and snow.
, it is difficult to withdraw troops.
Fortunately, the heavy rain turned into light rain in the past two days, and Chen Mu urgently dispatched a batch of raincoats from the rear. The rain should become lighter today, and the troops can almost be withdrawn overnight.
Chen Mu left the house. Now Zhao Yun is the busiest person in Hanoi. In order to resettle the families of the surrendered Montenegrin Army, he is building fields in the rear. Xu Huang occupied the entrance of Linlu Valley and guarded the newly built dam more than ten miles away.
It is too easy to build a dam when the water flow is low. Just like building a city wall, use wood as support and erect a high wall.
Similarly, in the lower reaches of the Huan River, Guan Yu's army also built a dam to store water. During this period, the Huan River surged and began to slowly flood the river. It rose through the moat and entered the Huan River City. The streets were already submerged. Yan Liangwen Chou in the city
They all thought it was just caused by heavy rain and did not feel any vigilance.
The main reason is that the weather has been too abnormal recently, with heavy rain and snow, so the scouts in the city can't go out. Fortunately, the food and grass in the city can still last for a while, so they are not in a hurry. They want to wait a few months for the weather to get warmer, and then start from the rear.
It’s not too late to transport food.
Because of the weather, it was impossible to go out for reconnaissance inside the city, so Guan Yu dug ditches outside the city. The ditches connected the Huan River outside Anyang City. Surrounding the city, there were almost several trenches two feet deep and two feet wide to divert the Huan Water.
The injection caused the water level of the river to drop a lot, which caused Yan Liangwen and Chou to laugh at him in the city.
They thought Guan Yu was helping them dredge the flood, and they all ridiculed Guan Yu outside the city for doing something stupid. Little did they know that in history, Cao Cao, despite the ridicule of the judge, flooded the entire Ye city!
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Of course, Cao Cao flooding Yecheng and Guan Yu flooding the Seventh Army are two completely different concepts.
According to historical records, Cao Cao dug a ditch outside Ye City, and then poured water from Zhangzhou into it, allowing the ditch to flow into the moat. The water level in the moat and ditch surged and overflowed the ground, causing the outside of Ye City to directly turn into a lake and swamp.
Food and grass outside the city could not be transported in, causing most of the people in the city to starve to death.
In other words, the so-called flooding of Yecheng is not a flood that destroyed the city at all. The water level in the city was at most over people's knees. In addition to making it impossible for vehicles transporting grain and grass to enter, it did not have any impact on the life in the city.
What big impact will it have?
The Seventh Army Flooded was different. It was a real flood. At that time, Pang De was stationed outside the city, and he was at odds with Cao Ren in the city. As a result, he encountered heavy rains, the Han River surged, and there was a flood outside the city, which destroyed the military camp.
All submerged.
According to historical data, the deepest water level at that time was as high as five or six feet, or more than ten meters deep. There was almost a vast ocean outside the city, and soldiers could only run to the mountains to avoid the flood.
Then Guan Yu's naval forces came in powerful ships, stormed Tipo, and shot arrows at the defenders on the mountain. Yu Jin was forced to surrender, and Pang De was captured alive.
For a time, Guan Yu was so powerful in China that he scared Cao Cao to the point where he almost considered moving the capital.
This is the entire process of flooding the Seventh Army.
It can be said that compared with Guan Yu's flood of seven armies, Cao Cao's water was like a child's urine, there is no comparison at all.
But again, flooded Yecheng may indeed be relatively watery, but as long as it is useful, it will be fine.
The vehicles transporting grain are two-wheeled carriages. If Chen Mu completes the same operation as Cao Cao, the Huan River will surge and completely flood the area around Anyang. Even if the water level is only above the knees, the grain transport fleet will still be unable to get in.
Last month there was heavy rain and heavy snow, and during this period it was still raining heavily. There was a series of extreme weather. According to spy reports, no new grain has been transported to the city for two months.
Thirty to forty thousand people eat and drink every day. Even if the food and grass in the city are piled up like mountains, there will definitely not be much left. As long as the strategy succeeds, Anyang will be defeated!
With this thought in mind, Chen Mu started to rush towards the dam at the entrance of Linlu Valley without stopping.
It is still broad daylight, but the sky outside looks like evening. The gloomy and sticky dark clouds seem to fall down and crush people. The deep Taihang Mountains in the distance are like a ferocious dark dragon. Occasionally, lightning cuts through the void.
, making people’s faces look pale.
In the pouring rain, Chen Mu was wearing a raincoat, and Zi Ying led him at high speed. Hundreds of heavy knights with black armor put down their heavy armor, and only one man and one horse followed with light armor. This mission was not very dangerous, so there was no need to ride alone.
One man and two horses, a hundred people are enough.
Dangyin is very close to the entrance of Linlu Valley, about fifty miles away, which is similar to the distance from Danyin to Anyang. After setting off in the afternoon, it took about an hour and arrived at the location about ten miles outside the entrance of Linlu Valley.
.
When he came over, he had already seen a canal four feet wide and two feet deep in the distance. The tumbling river water continued to flow to the outlet of Huanshui in front. There was a very large depression at the entrance, which was also Chen
Mu carefully selected the dam location.
Because the original terrain of this place was relatively low, it was a basin outside the mouth of the valley, covering an area of 1.7 square kilometers. Chen Mu sent people to expand and dig deeper here, and then built a dam at the outlet of the canal.
The reason why I chose this place is that this basin is second. The most important thing is that it is about ten miles away from the entrance of Linlu Valley and about twenty miles away from Anyang City. And the Yuan Army across the river will not have no important strategy in this area.
It is safer to be stationed in a local area.
The so-called dam is a thick wooden wall with the lower part deep into the ground and the rear supported by a large number of beams and columns. These beams and columns are all tied with ropes. The ropes are connected to the winches on the banks on both sides. Once the gate needs to be opened to release water,
When the water is flowing, a winch device is used to tear off the beams and columns to drain and release water.
It is very primitive, but it is indeed a commonly used method of building dams in ancient times. That is to say, they do not store much water. If it is a flood of the level of the Seventh Army, such a small dam will basically have no interception effect and will directly
It will be washed away by the flood and the dams on the shore will be destroyed by you.
At this time, several large openings were opened in the wooden wall. When the water overflows the ground water level above, it will flow into the Huanshui River through these openings. There is no way, it has been raining heavily in the past few days, and the pressure on the dam is very high. If the openings are not opened to release the water,
, will lead to early release of floods.
The excavation work on Guan Yu's side has been completed long ago, but he has not had time to retreat. If water is released directly upstream, not only Anyang will be flooded, but his military camp will also be flooded, so Guan Yu has to consider it.
After Chen Mu came over, Xu Huang, who was stationed on a high slope here, immediately led his military officers to greet him.
Before he could speak, Chen Mu asked: "Gongming, is there anything unusual?"
"Four Generals, there is nothing unusual!"
Xu Huang said with a smile: "It's snowing and raining heavily these days, and Yuan Jun on the other side of the mountain has no idea of coming over to check."
"Well, it seems that this bad weather has helped us a lot."
Chen Mu smiled and shook his head.
The Yuan Jun on the other side of the mountain refers to the Yuan Jun garrison on the other side of the mountainous area to the north of Linlu Valley Pass. In later generations, it was almost in the Yuecheng Reservoir and Fengfeng Mining Area. At this time, it was called Jiuhou City, and there were some rural pavilions. Yuan Shao was there.
Troops were stationed here to prevent Lin Lu's imperial army from attacking Yecheng from this direction.
This is also the reason why Chen Mu needs to control the mountain roads of Taihang Mountain, because almost all the roads in the plain area from Hanoi to Yecheng are blocked. Later, there were large-scale Yuan troops stationed in the Yuecheng Reservoir area, Anyang area, and Neihuang area.
make life difficult for.
And if you observe through satellite maps, you will see that in the mountainous area to the north of Linlu Valley in later generations, there is a place called Hezhang Township. This is the section of the southern foot of Fukou Xing. From here, you can directly penetrate into later generations along the Zhangshui River.
The location of Fengfeng Mining Area is less than fifty miles away from Yecheng, so it can be used as a surprise attack location.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Of course Chen Mu is not so crazy as to memorize the satellite map, but he has now integrated into this era, although he does not know the complete terrain structure on the satellite maps of later generations.
, but the clear and turbid Zhangshui runs through the entire Taihang Mountains. Not to mention the locals and the Black Mountain Army who live in it, even Yuan Shao probably knows it all and has already sent people to garrison nearby.
Therefore, he only used methods suitable for this era. As for Yuan Shao also knowing the Zhangshui Ancient Road, let’s not talk about it for now. It is as if the Ji Han people did not know the Yinping Ancient Road. Wasn’t it finally broken by Deng Ai? So?
Knowing it is one thing, being able to use it is another.
After confirming that there were no problems on Xu Huang's side, Chen Mu asked Xu Huang to make preparations in advance. He would first go to the Guan Yu military camp. He would send someone over after a while. When he determined to open the gate and release the water, he must execute the order immediately.
After Xu Huang made his promise, Chen Mu set off again in the rain. The group of people wore raincoats and galloped through the drizzle like ghosts in the cold sky.
The outlet of the canal is closer to Guan Yu, only about twenty miles away and can be reached in half an hour.
At this time, the outside of Anyang City had been excavated and was full of potholes. Several canals surrounding Anyang City were particularly conspicuous. These canals had a diversion effect and were eventually connected together to pour into the outer moat.
Since moats in ancient times mostly connected the city, as drinking water for residents in the city, although there were wells, the sources of the wells were mostly from the rivers outside. Therefore, once the Huan water began to surge significantly, the inner rivers and wells in the city would begin to rise.
Flood the city.
It won’t make the city full of boats, but it will definitely be no problem if the water is up to your knees.
By then, the entire periphery will be completely flooded, turning the surrounding area into a lake, and the lower reaches of the Huan River will be blocked. If you are lucky, it will be interesting to flood all the remaining grain in the city's granaries.
When the time comes, the soldiers in Anyang City will not respond to the calls from the sky and the sky, and the land and the earth will not work. I am afraid that they will only die of starvation.
Chen Mu bypassed the canal and saw from a distance that Guan Yu's army camp was packing up and saluting, preparing to evacuate. It was not to withdraw from Dangyin, but to withdraw from the area affected by the flood. They were only three or four miles away from Anyang City, and the upstream gate was opened.
, the lower reaches are flooded, and the camp will also be affected, so it must be relocated.
There were heavy snowfalls and heavy rains in the past few days, making it impossible to move. Today, the rain is less intense. Taking advantage of this opportunity, Guan Yu also quickly made arrangements, moved all the luggage that had been sorted before, onto the carriage, and covered it with bamboo mats to protect it from the rain.
, and then ordered the soldiers to demolish the camp and prepare to move to a place with higher ground that would not be flooded.
When Chen Mu came over, Guan Yu was commanding the front camp. Some soldiers who were watching the enemy's situation on the watchtower shouted reminders outside the stronghold. They heard that there were cavalry coming from a distance. Guan Yu looked around and saw vaguely the most serious enemy in the wind and rain.
The one in front was a BMW with purple hair. When he recognized that it was Ziying, he felt relieved.
When Chen Mu came closer, Guan Yu greeted him and waved, "Fourth brother!"
"Second brother."
Chen Mu got off his horse and stepped in the wet mud. He didn't bother to pay attention to whether his shoes would get wet or whether mud would float on his body. He asked aloud: "Are you ready?"
Guan Yu smiled and said: "Don't worry, everything is almost settled. Everything is in the back camp. When the time comes, just leave from the back camp."
"That's good."
Chen Mu nodded, and suddenly from the corner of his eye, he saw someone on the distant city wall holding the city head and watching. Because he was too far away, he couldn't see clearly. He could only vaguely see a few black spots looking towards this side.
Seeing that Chen Mu was looking towards the top of Anyang City, Guan Yu sneered and said, "This is Yan Liang's taunting me again. Last time he was digging a ditch outside the city, he even asked someone to write a letter to say thank you for my help.
He drained the water in the city. There is no way I can repay him for such a great kindness. When I celebrate the sun, he can come to my grave to express his feelings."
"Ah."
Chen Mu also chuckled and said: "I didn't expect that a rude man like Yan Liang would learn to be sarcastic and ridicule others."
"What is yin and yang strange energy?"
Guan Yu asked in confusion.
Chen Mu waved his hand: "This is just to ridicule, second brother, don't be angry. When the water gate opens, when he is swimming in Anyang City, let him be happy for a while. When we evacuate to the slope, he will be happy."
Can’t get up.”
"Hahahaha, okay, then I will have to see what kind of face he still has to dare to be arrogant in front of me!"
Guan Yu laughed loudly, stroking his beard and squinting his eyes to look into the distance.
The most troublesome thing about relocating a camp is to dismantle the camp. It is time-consuming and labor-intensive to cut down trees and build fences. Therefore, as long as you are not marching long distances and are closer, most of the temporary camps will be demolished and built somewhere else.
Guan Yu's army has been busy all day. All the baggage in the camp has been moved to a hilly and steep slope about two miles away from here. The baggage vehicles have been pulled back and forth hundreds of times, marching tents, siege equipment,
There are all kinds of weapons and equipment, food, grass and clothing, and all kinds of things. The nearly 30,000 troops have a lot of expenses, and it is far from being able to deal with them in a short time.
I was busy from day to night, and finally the relocation was completed. This was just the completion of the relocation, and the soldiers were busy setting up camp on the mountain. This place is a bit far away from Anyang City, about four miles, or 1.6 kilometers.
Looking from a distance, the city on the horizon is already very small.
Chen Mu and Guan Yu stood on the hillside, looking at the pitch-black city on the horizon in the night, with only the shadowy bonfire at the top of the city remaining. When they looked at each other, they could see the smile in each other's eyes.
