After Guan Yu learned from Zhuge Liang that the possibility of Yuan Shaojun building a dam upstream was blocking the river, he did not immediately take action. Instead, he waited for another day or two more, and waited until late at night on the first day of July before officially taking action.

On the one hand, thousands of cavalry attacks and sabotages at night require a certain amount of preparation time. Guan Yu also needs to make good plans for combat. How many troops should be mobilized and the structure should be carefully adjusted.

On the other hand, Guan Yu judged that Yuan Shaojun was sure to be more alert to the siege defense line during the process of building a catapult position. Once the catapult car and siege weapons were all built and put into use, and made some progress, he would breathe a sigh of relief. And what he was waiting for was this opportunity to relax and strive to achieve twice the result with half the effort.

I have to say that Guan Yu's psychological thinking about the enemy is still very good.

Ordinary viewers may not be able to react immediately to this truth, but you can understand it with an example:

For any player who plays games like the Age of Empires, Fortresses, Warcraft, etc., if your packing trolley advances to the launching position and unfolds, you will definitely be the most nervous.

You will try your best to get the spearmen and crossbowmen to come forward to guard against the enemy cavalry to prevent the enemy from rushing out of the city gate to destroy your catapult position. When your catapult frame starts to output wildly, and smash the castle arrow tower walls on the opposite side, your nervousness will definitely be relaxed and you feel stable. The enemy has not yet rushed out and it is too late.

This is what Guan Yu takes advantage of.

The last morning of June was exactly the day when Yuan Shaojun's catapulted car positions were completed.

During the day, each wall of Yewang City faced dozens of newly built trenchers on the east and south sides of each wall, with the firepower of more than one hundred kilograms of stone bullets every few minutes, and frantically outputted to the city wall and tower.

Yuan Shao's official siege also increased the intensity again. Not only were there thousands of crossbowmen hiding behind the wooden shield outside the city wall, but there were also the first iron armored Ruizhe holding a round shield, steel knife, nail hammer and short axe, following the ladder truck ants to climb the city.

The trench bridge chariot and the city-digging wooden donkey passed through the filled trench pits and the demolished sheep and horse walls, and also reached the base of the city walls, especially at the wall sections that had been damaged by the catapult truck and collapsed and became lowered. Construction continued to be dug hard.

After all, the accuracy of the leveraged catapult in this era is still a problem, which leads to the problem of "it is impossible for two shells to fall into the same crater", which has become even more serious.

Often, the gaps that were smashed by the stones in front could not be expanded during the second and third rounds of shooting. The new stone hit a few dozen steps away next to the old pit and opened a new pit. In this case, it is necessary to dig the city wooden donkey cart to make up the old pit to ensure that the old pit was completely dug and collapsed to the soldiers can climb up along the slope ant.

After a whole day of bloody storm, Yuan Jun had already created four or five gaps in the Yewang City wall that collapsed by about half.

Originally, before the war started, Guan Yu raised the Yewang's city wall to three meters, but the gaps were basically only ten or fifteen meters away, and the slope was not as steep as the beginning. The collapsed rammed earth formed a footrest slope, which was only about sixty degrees inclined. You could slowly climb up with your hands and feet lying on the soil.

Fortunately, such a gap is still not enough to break the city. Whenever Yuan's soldiers swarmed towards these gaps, they were pushed back by Guan Yu's iron-armored soldiers who were condescending to each other.

But this kind of fight is also more bloody than the previous hand-to-hand combat in the field defense line outside the city.

Although the defense has the advantage of being condescending, every armored stalker can exchange more Yuan Jun's death soldiers before being injured in hand-to-hand combat.

However, because the terrain of the battle location was not good, the soldiers under Guan Yu had to stand on the shaking slope after the landslide defended, and were often wounded by the wounded soldiers of the opposite Yuan Bing with the mentality of "dragging a cushion before death".

Many Yuan soldiers were injured and were red in their eyes. Two or three of them fought, and they hugged the iron armored soldiers who could not break the defense, and then fell down the gap in the city wall together.

Those Yuan soldiers who fell from a height of 1.5 meters or 2 meters may not necessarily die. Guan Yu's army soldiers were wearing dozens of kilograms of steel and were often injured even more when they were dropped. This is the best blunt weapon injury, which is very restrained by the iron armored soldiers.

Moreover, it is summer now, and the battle between iron armored soldiers is very hard, and they will not wear the anti-scratch cotton jacket lining that they only wear in winter. There is no buffering at all. When they fall, they will vomit blood and get seriously injured in the internal organs. If they are crazily finished, almost every Han soldier who falls into the city will definitely die.

The total number of casualties in the Han army seemed not as high as the previous field defense battles, but the mortality rate was extremely high.

Guan Yu personally supervised the battle for one morning. In the afternoon, he saw that although the scene was tragic, it was impossible to be broken into the city today, so he steadily chose to go back and rest, allowing his son Guan Ping and several other civil servants to supervise the defense of the city.

Guan Ping was already slightly shocked by this bloody "tugging people on the back before death" style of playing, and he was a little suspicious of his life. After all, it has only been two years since he followed his father to fight. He has never seen both sides so hard on the bloody attack and defense city battles.

Later, when I saw my father insisting on going back for a nap so firmly and continuing to adjust his biological clock so that he could attack in the middle of the night, Guan Ping's mood stabilized a little, and secretly warned himself: There is nothing to worry about, it's just life-changing consumption. My father felt that there was no problem, so he definitely had no problem.

...

During the bloody battle throughout the day, Yuan's casualties were almost as close to the total casualties in the previous four days. However, the number of deaths in the Han army was more than twice the total of the previous four days! The total casualties were only the same as the total of the previous four days.

During the five-day siege, the Han army suffered a total of more than 2,000 casualties, and today it was more than 1,000 and more than 600 died. In the first four days, less than 100 died every day, especially because the crossbow soldiers were protected by iron armor, and minor injuries accounted for half.

After nightfall, Yuan Jun finally retreated and licked the wounds well. After all, an army of hundreds of thousands of people and ordinary soldiers had night blindness. It was impossible to eat animal livers or other foods that supplement night vision abilities like elite troops, and they could not afford to raise them at all. There is no way to start siege at night.

Zhuge Liang and Guan Yu estimated that the walls of Yewang City could last for at least two days under the fierce attack of the trencher before they could be completely smashed into an almost smooth gap, allowing the siege to rush in without any ladders to fight hand-to-hand combat.

Of course, this speed is already included in the Han army's restoration of the gap in the city wall overnight. In addition, even if the city wall is broken, it does not mean that the city has fallen. After all, there are more than 20,000 elite soldiers in the city.

Zhuge Liang could dig simple trenches and simple low walls on the inside of the break, and set up defenses and fight in the streets. As long as the soldiers are strong enough to exchange their lives with Yuan's army, it would not be easy to kill all the 20,000 defenders. Therefore, Zhuge Liang estimated that even if the city wall was broken, he could guard at least five more days before he would worry about "exhausting ammunition and rescuing" and had to break through.

By doing this, you can still stay for more than seven or eight days.

No matter what, after both sides had a large number of catapults, it was really difficult to defend the medium-sized city at the county level.

Only those city passes with natural terrain, or particularly high and steep cities like Chang'an and Luoyang can defend for several months or longer. The siege battles of other cities can be shortened to more than half a month to one month.

After halfway through the second update, Zhuge Liang was already a little trapped because he was patrolling the city and supervising the battle during the day, but he still insisted on sending Guan Yu to the west gate.

The city tower of the Wild King Ximen was the most severely damaged in the four gate tower. During the daytime siege, several major load-bearing stone pillars were broken by huge rocks, and most of the city tower collapsed. Zhuge Liang and others had to make a living.

Zhuge Liang did not forget to take care of the last care: "Be careful, Yuan Shao suffered heavy casualties today and was exhausted, but his progress was good. He should not be too alert at night. At most, he would only be wary of robbing the camp. After leaving the west gate, he would go to the southwest corner and pass between Zhang He and Gaolan's camp. It should be the least dynamic."

"Zhuge Xianniang has taken care of, don't worry, I'll come when I go."

Guan Yu got on the horse with a knife, waved his hand, and five thousand cavalrymen tied their hands, bandaged the burlap with their horses' hooves, quietly opened the Xicheng Gate, and slowly left the city in two batches.

Guan Yu also spent his time in the attacking troops tonight, in terms of the composition of troops and equipment.

He did not let all the heavy cavalry in the army wear iron armor, but slightly reduced the proportion of heavy cavalry. In the end, there were only two thousand iron armored cavalry and three thousand light cavalry with leather armor and leather vests.

Guan Yu is not very good at commanding archers and cavalry, especially Youzhou cavalry, which is Zhao Yun's specialty. Therefore, Guan Yu's light cavalry is more lightened in armor, and his combat skills are still mainly melee slashing and sprinting.

The reason why he had to make such arrangements was to increase the proportion of light cavalry so high, because if the Yuan army could really kill the dam-building troops and destroy the embankment, the water level would rise. The heavy cavalry retreated in an environment with a certain depth of water and easily fell into mud, and the soldiers could easily not stand up after falling into the water and drowned directly.

Therefore, Guan Yu was preparing to let the heavy cavalry perform the task of robbing the camp and breaking through. Once the enemy's organized resistance was broken, the heavy cavalry should retreat immediately.

The light cavalry stayed to carry out fortification destruction tasks, so it would probably take half an hour to dig the already built cofferdam dam. This time difference is enough for the heavy cavalry to split their troops and withdraw back to the city.

After flooding, the light cavalry then retreated carefully along the Qinshui to avoid being washed away. It also fully considered the passing issue of different troops for different terrain.

Guan Yu's iron-armored cavalry troops first left the city for about a cup of tea, and chose the route between Zhang He's Gaolan camp and the camp on the Gaolan side. At the same time, the light cavalry who set out later chose the route relatively close to Zhang He's camp. Including the speed difference between the light and heavy cavalry, they could almost reach the river-blocking camp at the same time.

On the night after the war, and I felt that there was a great hope for victory, Yuan Shao's army was indeed relatively relaxed. There were still many patrol soldiers in Gaolan Camp, but they were all focused on preventing the robbery.

Guan Yu's iron cavalry was discovered by Gao Lan's scout cavalry less than five miles away. However, Guan Yu's army used a small number of prisoners of war who had been transformed with Ju Su in the previous stalemate of the Yuan army, and was the vanguard.

Although these soldiers surrendered to Guan Yu for about half a year, they were all identified and absolutely reliable, and they sincerely surrendered to Liu Bei's camp. Guan Yu asked them to shout, saying that they were Zhang He's patrol cavalry and patrol to ensure the area between Zhang He's camp and the river-blocking camp in the rear.

This move was also taught by Zhuge Liang, but it was not considered a risky move.

This is much more realistic than the kind of act of "the troops who went to Wuchao to burn grain when they were in the Battle of Guandu in history, "the troops who went to Wuchao to burn grain, but they pretended to be the troops who sent Jiang Qi to protect grain by Yuan Shao."

Moreover, Guan Yu's answer was very clever. When the scout of Gao Lan's army saw that the other party was not heading towards Gao Lan's besieged camp, but patrolled by, he did not directly suspicion and attack.

Even if I was a little uncertain, I just went back to the camp and reported to Gao Lan's night patrol officer first, strengthening the night warning of the camp. They guessed that if Guan Yu really sent these to rob the camp, I would just stabilize them first and give their own people more time to prepare. Isn't it just a trick?

As for the matter of Tuo Yi blocking the river and building a dam upstream, even Zhang He and Gao Lan and other generals themselves did not know the arrangements, because it was not part of the Ye Wang's siege, and was directly commanded by Yuan Shao. Zhang He and Gao Lan thought that Tuo Yi was just left behind as a reserve team, and only after the siege in front was seriously injured and injured, let Tuo Yi add it.

Yuan Shao felt that this was for the sake of keeping it secret. There was no need for Zhang He and Gao Lan to know too many things that shouldn't have known. Anyway, it would take a lot of time to prepare for the idle chess of Tuo Yi. After he was almost ready, he needed other troops to cooperate, and it would not be too late to announce it again. In this way, the sneak attack effect on Guan Yu can achieve the best and most sudden.

Guan Yu's iron cavalry quietly passed through the northwest corner of the Gaolan defense zone in the south of the city. After a while, his light cavalry troops used the same excuse to pass through the southeast corner of the Zhanghe defense zone in the west of the city, nothing more than an excuse to "declare himself to be the night patrol cavalry in the Gaolan camp in front of Zhang He's scout troops."

Zhang He and Gao Lan were also considered famous generals. After going around, they also got up to investigate the abnormal situation and recorded it on the record. They also strengthened the prevention and robbery measures in their camp. Unfortunately, all this was too late, and they had no time to notify Tuo Yi, who was more than ten miles behind them.

The eleven or two miles away was a journey of 11 or 2 miles for the cavalry. When Guan Yu arrived at the Tuoyi River Barrier Camp, it was just three o'clock.

Even Guan Yu had become addicted to this trick because he had previously called Zhang He and Gao Lan's troops successfully used this trick. Finally, he went to the front three miles of Tuoyi Camp and was discovered by Tuoyi's scout patrol team. He used it for the third time, trying to delay for a certain amount of time.

The scout of Que Yi did not expect that "Zhang He and Gao Lan in front of him did not find any problem, nor were they attacked. Guan Yu would bypass Zhang and Gao sneaked into our army on the second line."

It was the moment when Guan Yu officially threw out the hook and pulled the wall of the Guma Village and launched a charge that he reacted.

Two thousand iron-armored cavalry first rushed into the camp like a torrent, regardless of the enemy or me. As long as they saw no one wearing bright and forged steel breastplates, they would sprint and kill, and any infantry that encountered walking would be killed indiscriminately.

Anyway, Guan Yu is an iron cavalry, so as long as he insists on the idea of ​​"killing infantry when he sees infantry", even in the darkness and chaos, he will definitely not kill the wrong person. A few iron cavalrymen fell off their horses and became infantrymen, so it is blamed for their bad luck and seeking blessings.

There were not many torches in the camp, and there was almost no moonlight at the end of the month. Under the dark light, the camp was suddenly killed by the robbery, and the iron cavalry was trampled and rushed around. Even though Tuo Yi was extremely strict in the army, the entire camp was still in an instant.

Que Yi is already a famous general who is good at breaking cavalry in the world. At that time, Baima Yicong and Zhang Chun's Wuhuan cavalry were both killed by Que Yi's Xiandeng Dead Soldier.

However, in this dark night, except for the Central Army camp where Quyi was originally surrounded by chariots, Guan Yu was in conflict for a while, and the camps outside were almost completely broken. More than 20,000 troops and horses scattered in birds and beasts, only 3,000 people in the Central Army were organizing resistance. The surrounding 20,000 people were all scattered, and they were killed by the iron cavalry that clashed left and right and left to drift.

Guan Yu's three thousand light cavalry also arrived. They changed the previous style of attacking the iron cavalry's central palace and hitting their hearts, but instead ran around the camp in a circular formation.

Whenever you see the escaped infantry, you will shoot arrows and kill them in large numbers, killing more and driving away the defeated soldiers back and trampling on each other with the newly rushed out from behind.

In this way, the iron cavalry was ruined and the light cavalry surrounded him in circles. The former was like the blade of a mixing juicer, and the latter was like the wall of a mixing juicer. The wall of the can collides the pieces of food that were knocked away by the blade and force them back to the edge of the blade. It was crushed twice and three times. It didn't take long for the whole piece of fruit and vegetables to be crumbled into a paste.

Tuo Yi's troops were killed in a terrible way, and they had no place to run like a headless fly. Many of them even saw the pursuit soldiers who did not have Guan Yu in the Qinshui River on the north side, so they jumped into the river without hesitation and wanted to swim to the other side to escape.

Guan Yu got all this up and immediately commanded the Iron Cavalry from Guan Ping to return to the city by land. He took three thousand light cavalry and immediately excavated the embankment and cofferdam left by Tuo Yi.

At the same time, Guan Yu ordered the light cavalry to set fires around the periphery of the Quyi camp, causing big noises, making Zhang He Gao Lan realize that "the Quyi camp is still fighting fiercely."

Only by conveying this illusion can Zhang He and Gao Lan not pay attention to the Iron Cavalry who went back to break through. They will feel that those people are just "the cowardly deserters of Guan Yu's subordinates, and Guan Yu's cavalry's main attack force is still fighting in Tuo Yi's camp." This will protect the retreat success rate of Guan Ping and the Iron Cavalry, allowing Zhang He to spend less energy to bother them.

Shortly after making the arrangements, as the light cavalry beside Guan Yu dismounted and began to dig and destroy the cofferdam, they soon discovered that the situation was different from what Guan Yu said at the beginning.

An officer of the Sima level of the army reported to Guan Yu in a hurry:

"Taiwei, Tuo Yi's men had been digging water diversion canals south before. We lit a torch and ran around. It seemed that we would dig until we entered the Ji River! But it is still very shallow now, but this depression in the south of Henan was flooded and could not continue to flow south."

Guan Yu was puzzled for a moment: "They want to flood the Yewang City, why are they digging so far? If they dig it into the Ji River, wouldn't they all flow directly into the Yellow River in the future? At most, the Ji River level will rise. Isn't they want to flood the Yewang but to flood Wen County? That's not enough.

No matter so much, continue to build and destroy it quickly. You roughly draw a few strokes of what you see, or remember it roughly, and ask Zhuge Changshi after you go back."

Guan Yu's troops dug for half a quarter of an hour, and the embankment had been damaged and several broken holes were blocked. The water flow that had been blocked for several days was poured down along the Qinshui road again. It didn't take long before the dam collapsed and the water level had risen several feet higher than the Qinshui water level on normal days.

You can already hear Zhang He in the distance, and Gao Lan led his troops to surround him. The vanguard was a cavalry, and there were also a large group of infantry troops who wanted to block the return route of the light cavalry that destroyed the embankment of Guan Yu.

Guan Yu immediately assembled his troops and returned to the army to first fight Zhang He Gaolan's cavalry. The two sides fought one after another. Because Guan Yu's light cavalry did not have iron armor, they did not gain any advantage in this chaos.

After the bloody and short battle, the two armies each lost hundreds of people. Zhang He and Gao Lan were unwilling to fight Guan Yu alone in the past, but wanted to hold Guan Yu and wait for their infantry to meet. Therefore, under the fierce pressure of Guan Yu, Zhang He and Gao Lan chose to temporarily retreat and reorganize the formation.

But at this time, the water around the battlefield had been flooded more than one foot deep, and it was very difficult to move. It would be difficult for the cavalry to jog slowly at such a depth of water, so it would be difficult for the infantry to move. Fortunately, the water flow rate was not very fast, otherwise the infantry could fall down at one foot, and they might not be able to get up.

Guan Yu's troops hid away from the most surging position of the water flow because they were huddled on the dam at the beginning.
To be continued...
