When the soldiers in Anyang City changed their defenses at night, everyone was dumbfounded.
The military camp was flooded. Since Anyang was built as a military town, there were not tents in the city, but barracks.
The rammed-earth structure of the barracks can accommodate more than fifty soldiers. The room conditions are simple and the people live in Datongbu. There is an earthen kang built on the left and right walls, and there are more than 20 beds densely packed on it.
These earthen kangs were only knee-high from the ground, and the water level was not that high at that time. It was only when the soldiers who got up in the middle of the night to change defenses stumbled and stepped into the water that they realized something was wrong.
Because they were afraid of the roar of the camp, the soldiers' weapons and armor were stored in a warehouse elsewhere in the barracks. In the cold winter, they often slept in their clothes. After getting up, they went directly to the ground to put on their shoes, and ended up with two feet
Drifting directly into the cold river water was frightening.
"The barracks is flooded!"
Someone shouted, and the shouting woke up many soldiers around. Only then did everyone realize that the ground had been filled with water for some time. It had reached a height of one foot (23.1cm), and it continued to grow at a speed visible to the naked eye.
The soldiers hurriedly rushed out of the house.
The sound of gurgling and gurgling outside continued, and everyone thought it was because of the heavy rain, which caused the river to overflow and the city to accumulate water. This had happened once before, and it was Guan Yu who dug ditches outside the city to help them rescue them, which made Yan Liang laugh.
As a result, many soldiers came out of their houses and discovered that it had not rained at all outside. The sky was still overcast, but the rain had stopped four hours ago yesterday evening, and now not a drop of rain fell from the sky.
Soon the news of the inexplicable rising water in the city spread throughout the army. After a while, the news of the flash flood spread throughout the army, so they slept when they needed to, and continued to change defenses when they needed to.
The news of the flash flood was reported by the soldiers who patrolled the city before. They were all eyewitnesses. This situation is very common. For example, it is not raining here in Anyang, but it is raining in the Taihang Mountains, and the water flows into the upper reaches of the Huan River.
The Huan River surged, causing the city to be flooded. This is a normal natural phenomenon, and the water will recede on its own in two days.
Yan Liang Wen Chou also got the news. He was shocked at first and came out of his mansion to see what was going on. Later someone came to report that a flash flood had occurred in the upper reaches of the Huan River and the lower reaches were submerged, so he went back and continued to sleep soundly.
, according to past experience, when the rain stops upstream and the water flows downstream, the city will become safer.
The most important thing is that in the construction of ancient cities, the location of the granary must not be too far from the water source, but also must be on a higher ground. The granary in Anyang City is at the highest point of the terrain, and the heavy rains a few days ago did not flood it.
It's very safe. As long as the food is safe, the city will be fine.
With this idea in mind, Yan Liangwen Chou naturally has nothing to worry about.
When it dawned the next day, the water that was only one foot high last night had risen to two feet high, submerging the bunks of many barracks. The soldiers could only hold their mattresses and hide in higher warehouses.
Living there, because two-thirds of the granary has been eaten and there is a large open space, the soldiers whose barracks were flooded can only deal with it in the warehouse first.
Min Chun, Yan Liang, Wen Chou and other generals in the city came to the top of the city. They first observed the water level in the city, and then looked at the billowing Huan River outside the city. The Huan River was overflowing, constantly washing away the soil on both sides, and the water level was
It flooded the surrounding ground, trees on both sides of the river were covered with water, and the pontoons that previously connected the other side were washed away.
It doesn't matter if the pontoon bridge collapses. It's not too difficult to build a pontoon bridge. The key is that the surrounding area is submerged for dozens of miles. The water level is as deep as the knees. Both sides of the river directly turn into swamps. If grain and grass are to be transported to the other side, the muddy swamp is the first
An insurmountable obstacle, on which it is impossible for wheels to travel.
Even if the carriage can solve the problem of mud blocking the road and causing the wheels to sink in, what about crossing the river? The reason Anyang was built on the south bank of the Huan River is to play a strategic military role. The Huan River is very long, and it is really difficult for the enemy to cross the river elsewhere.
It is too easy. If it is built north of Huan River, it will have no military significance.
Only if it is built on the south bank of the Huan River, can it threaten the safety of the hinterland of Hanoi and even Luoyang after the main force of the Luoyang Army crosses the river. But now the Huan River has surged, the current is rapid, and the pontoon has been washed away. Is it possible to use ships to transport grain so quickly?
If the flow rate is too high, the boat will be destroyed and people will be killed?
Therefore, the climate in ancient wars is really a big problem. Sometimes when you can obviously defeat your opponent, it will suddenly rain and then blow gusts of wind, and then there will be snow, drought, floods, hail, earthquakes, and natural disasters.
Emerging in endlessly.
Min Chun saw the devastation inside and outside the city and was so angry that he slapped the wall hard: "Damn it, why did a flash flood suddenly break out again? Now there is only less than a month of food and grass left in the city, and the pontoon bridges have been destroyed.
If it collapses and the other side is flooded, how can we transport food and grass!"
Yan Liang waved his hand and said nonchalantly: "The flash flood is nothing more than a sudden heavy rain in the Five Elements Mountains, causing flooding in the upper reaches of the Huan River. After the rain stops, the water flow will inevitably drop. There is no need to worry about it. The pontoon bridge will be built at that time.
, it will be fine once the grain and grass are brought in again, can it still rain for a month?"
"Yeah, it's just a small matter. The weather should get a little warmer in a month, so don't worry."
Wen Chou didn't think there was any problem.
We have seen rivers surge and flood cities before. After a few days, the rain stops, and when all the water flows downstream, the water level will naturally drop.
However, Min Chun was still worried and said: "Two generals, the situation is urgent, so you must be worried."
"It's okay, let's see again in a few days."
Several people inspected the city wall and soon came to the south gate. They saw that the water in the south gate was also flooding. The ditches dug by Guan Yu were now overflowing. The turbid river water continued to pour into the moat, causing the moat to flow into the city through the water gate.
city river, and then spread to the streets.
This chapter is not over yet, please click on the next page to continue reading! At this moment, Min Chun suddenly remembered something and said quickly: "Oh no, there is a well in the city. Send someone to see if the water in the well is still clear?"
"Master, I checked it last night when I was fetching water. It's quite clear."
Soldiers reported back.
"That's good, that's good."
Min Chun finally felt relieved. What he was most afraid of now was that the wells would become turbid, and the soldiers would have to drink dirty water.
It is not unknown to the ancients that drinking dirty water can cause stomach upset, but more often than not, drinking poisonous water to quench thirst is a last resort.
It was only then that everyone noticed that Guan Yu's army had built a camp on a hillside in the distance. It was far away from the ground and did not allow water to enter the camp.
"Strange, why did Guan Yu know that a flood would flood the city today?"
Yan Liang wondered: "I remember that when there was a flood a few days ago, his camp was flooded. Today, when the rain stopped, he moved to the mountains instead?"
Wen Chou said casually: "Isn't Xu Huang in Linli? Linli is on the upper reaches of the Huan River. Perhaps Xu Huang told him that it was raining heavily in the Five Elements Mountains and the lower reaches of the Huan River might be flooded, so he moved there."
"That's true."
Yan Liang nodded, and suddenly remembered something funny, and said cheerfully: "That Guan Yu is really stupid. I also remembered the last time he helped us dig and build canals and dredge the rivers. It's a pity that he didn't dig much.
If we dig dozens more, maybe today’s water will also be drained by them.”
"Hahahaha, I have been in the army for many years, and this is the first time I have seen such kind-hearted enemies. People say that Liu Xuande of Qingzhou is benevolent and righteous, but I think they are stupid because of their benevolence and righteousness. They fight on the battlefield and pay attention to digging canals and water for the enemy. How can they be so
Stupid people."
Wen Chou also laughed in agreement.
In fact, Guan Yu helped them dig ditches a few days ago, which really helped them a lot. At first, they thought Guan Yu was digging tunnels, so they were very wary.
But after thinking about it for a long time, Anyang was built on the edge of the Huan River. In addition to its important strategic position, there is another problem: the soil on both sides of the river is relatively soft. If a tunnel is dug, it will easily cause the tunnel to collapse.
When we look at the history books of various dynasties, we will find that if there are records of digging tunnels to siege cities in ancient sieges, the locations were often in the north rather than the south, and the soil was often in harder areas rather than soft areas. This is because
This reason.
Anyang is at the foot of the Taihang Mountains. There are many rivers nearby. The underground water resources flowing from the Taihang Mountains are abundant. It is easy to dig water wells, but it is difficult to dig tunnels.
Therefore, when Guan Yu dug tunnels, he was digging his own grave. After Yan Liang and Wen Chou discovered this situation, they never worried about this problem again.
However, Min Chun looked at the canals outside the city, frowned and stared at them for a long time, and murmured to himself: "Something's wrong, something's wrong."
"What's wrong?"
Yan Liang asked in confusion.
"I always felt that something was wrong. Since Guan Yu could choose to move up the mountain, why did he have to dig ditches?"
Min Chun noticed something was wrong and said, "Isn't this superfluous?"
Wen Chou thought for a while and said, "Perhaps he thinks that digging ditches is not a big deal, so he simply moves the camp to settle down once and for all?"
Anyang City was not the only one to benefit from digging ditches. During the previous heavy rains, Guan Yu's military camp was also flooded. With the ditches draining water, the water in the camp dropped. Therefore, they had no doubts about Guan Yu's digging of ditches.
But Min Chun felt that since the camp could be relocated from the beginning, why did they dig a canal? It also helped them drain water from the city. Isn't this an act of fools?
But after thinking carefully for a long time, I couldn't figure out the reason, so I could only harbor the doubts in my heart and stop talking.
In fact, these canals were not originally used to store water, but were used to divert the flow of water from the Huan River to turn a large area outside the city into a marshland, forming a swamp area.
Because the overall terrain of our country is high in the west and low in the east, the moat connects the Huan River. The Huan River surges and floods occur in the city. However, the damage outside the city will not be too serious. The water will flow downstream on its own and will not take the initiative.
It flows to the southwest where the terrain is higher.
In this way, the southwest area of the city would be flooded for a few miles at most, rather than dozens of miles.
After a large number of canals were used to divert water, the water in the canals surged, so that the south area of the city also became a marsh country. In addition, the terrain in the east is low, and the water will flow in the same direction as the Huan River. Therefore, the role of these canals is to bring Anyang
A large area in the south and east of the city was included in the swamp, forcing Yan Liang to flee from the east downstream of Huan River when he abandoned the city.
It can be said that this routine is a chain of links, first storing water, then digging trenches, and finally draining water. On the basis of Cao Cao's flooding of Ye City, it also mixed psychological tactics and climate tactics. The defenders in Anyang City seemed to have
Like a turtle in a urn, it cannot escape from his grasp.
In the next few days, the water outside Anyang City still showed no downward trend. Yan Liangwen and Chou Minchun didn’t know that Chen Mu and Tongtong were pumping water into Qishui. Now the two rivers are pouring water into Huanshui together, which is equivalent to the water of three rivers.
The flow of water poured into a river at the same time, and the Huan River had an unprecedented amount of water. The rolling floods continued to overflow, and it was impossible to let the water level drop.
In fact, the downstream has long been submerged at this time. The downstream dam is at the narrowest point of the river. It was built two months ago during the dry season of Huanshui River. This time, the dam is not made of wood, but of cement.
The construction is quite strong, but it cannot hold up the water flow and spreads directly across the ground, no longer passing through the river.
The swollen river water diverged from both sides of the left and right river channels. Due to terrain problems, the river water on the left side flooded a large plain area in the hinterland of Wei County, causing great flooding in lower-lying areas, and finally flowed into clear water.
The river water branched off on the right side and flooded the Neihuang and Fanyang areas in the downstream area almost completely. Then the waves continued to flood, flowing into Huangze, and finally merged into the Guda River.
Historically, Cao Cao only dug the Zhang River and turned the forty miles around Yecheng into a marsh country. But Chen Mu dug three rivers. Even if these three rivers were taken individually, they were not as big as the Zhang River, but the three rivers combined
Together, they are definitely twice as powerful as Zhangshui, and their power is far greater than that of Cao Cao.
Not only did it submerge tens of miles around Anyang, but many of Yuan's army's defense areas, bunkers, sentries, and camps in the north became disaster areas. The most uncomfortable water level was not deep enough to allow boats to be used, but it was not shallow enough to allow carriages to pass, and almost only
Yuan Jun suffered greatly from being able to walk on foot.
Yan Liangwen and Chou Minchun still hoped that in a few days, the rain would stop in the Taihang Mountains. But after waiting for nearly ten days, the water level of the Huan River still showed no sign of falling. The city was still flooded with water, and even the wells were gradually drying up.
Become turbid.
Such a terrible situation suddenly made the three of them full of melancholy. Looking at the mountains in the distance, Guan Yu's army remained motionless. A large number of soldiers guarded them tightly, obviously watching their jokes.
What's even more uncomfortable is that at this moment, a horse galloped outside the city and shot a letter into the pillars of the city tower with extremely superb archery skills.
The three of them opened the letter and saw that it was actually a taunting letter from Guan Yu, asking him how he felt about soaking in the water.
Yan Liang was anxious and angry for a while. A few days ago, he wrote a letter to ridicule Guan Yu, but Guan Yu responded in the blink of an eye. It was really the way of heaven and reincarnation.
The most important thing was that the letter was full of ridicule and said that he was hiding in the city like a woman and did not dare to come out to fight with him.
Being said to be a woman at that time was definitely a big humiliation. Zhuge Liang gave Sima Yi women's clothes and forced Sima Yi to fight, which shows the mystery.
As a military commander, Yan Liang was called a sissy. He was so angry that he tore the letter in his hand into pieces and lay on the top of the city. His eyes were red and fierce, and he looked at the camp outside the city fiercely.
