Han Sui’s tactical thinking on this battle cannot be said to be wrong.

Indeed, for enemies who are camping on the back, the key to defeating them is not to kill and have vitality, but to destroy the enemy to the critical point of morale collapse.

This is quite like playing the Three Kingdoms game:

If a unit with 5,000 people and morale is consumed at the speed of "death of 300 people per round, and morale drops by twenty points at the same time", then as long as the unit has lasted for five rounds, the battle will be over when "there are 3,500 people left, but morale has fallen to zero", the battle will be over.

If the attacking side gives up because of his feelings of pain and suffering, and adds a morale to the enemy when he beats the opponent to the point where "there are 3,800 people left and the morale is twenty", and then gives the enemy a morale-returning BUFF. That will be the result of all his efforts.

Han Sui is an old thief for more than ten years, so he would not know this truth.

But unfortunately, in the real world, he cannot see the morale trough value of Guan Yu's army like in the game. He can only infer based on his previous combat experience.

The prediction that "soldiers who camped on the back will lose their morale when they are attacked continuously by the enemy in succession" is based on the premise that the other party has no way out and that the ferry is not enough, it is easy to rob the ship and escape first.

In fact, the Guan Yu soldiers were all very motivated because they knew that the caravans that Guan Yu stayed in the camp were enough to carry everyone away, and there were not many supplies in the camp, and they had already been piled up and hidden on high places.

These caravans can drive from Tao River to here along the way. Even in the main stream of the Yellow River, as long as the waves are not rushing, they can slowly cross it. Although the Yellow River near Lanzhou has already gathered the water volume of Tao and Huang, it is still incomparable to the runoff volume of the middle and lower reaches, and is not as large as the water volume of the Wei River near Chang'an.

The morale of Guan Yu's army was very stable, and everyone knew that they had a way out. Guan Yu told them that as long as they lasted for a day and a half, they would have a day to make a breakthrough. The enemy's army would flood the upstream. Why would they not fight to the death?

What's more, Guan Yu is famous for being "proud of scholars and officials and compassionate with his soldiers", with strict military management, strict rules and regulations, and sharing weal and woe. The more than 5,000 people who could be left here by him were all the most direct troops.

Han Sui hoped that Guan Yu's army would be defeated due to the morale collapse caused by the backwater, so he made a completely wrong idea.

The first wave of offensives of the three-way coalition forces was from Chen hour in the morning to Si hour. After Yan Xing retreated, the second wave of troops continued to attack from Si hour until noon. The casualties of the rebels were much greater than the first wave.

A total of three or four thousand people were injured in the fierce attack on the camp. More than two thousand people were killed and injured in Han Sui's troops, and more than one thousand and seven or eight hundred people were killed in Song Jian and Yang Qianwan.

Such tragic mincing made Song Jian and Yang Qianwan become passive and lazy. They were originally invited by Han Sui to share the stolen goods together, but who knew that the stolen goods would have to fill so many lives in them by themselves, which was not cost-effective.

The initial fierce attack was just because the spirit was strong and the morale of the army was available, so it was wasteful if the attack was not fierce. Now that the morale has passed, it would be unwise to fight to the death.

In fact, the three-way coalition forces seem to have suffered heavy casualties, but in fact they have suffered less than one-tenth of the total force. It is normal to slow down the pace after the loss reaches this point.

As friendly forces became more and more passive, Han Sui had no choice, especially since it was still the seventh month of the lunar calendar, the sun was in the sky, and when the noon was the hottest, the soldiers were losing their strength very quickly.

Just when Han Sui could hardly hold on, Guan Yu gave him the last blow. Guan Yu seized the time when Yang Qianwan and Song Jian retreated slightly, and almost as if they were killing chickens to warn the monkey, he personally led the team to retaliate against Han Sui's attack troops, and sent only a few hundred cavalry reserves to carry out a counterattack.

At the opening of the camp gate on the east side, the camp first cut out a clearing, then covered the gap on both sides, and then Guan Yu rushed out with his cavalry.

Li Kan, the general of Han Sui who was supervising the battle on the front, was caught off guard and quickly got on the horse to fight. He also called his personal soldiers around him to cover up and kill Guan Yu.

Guan Yu slashed his head, and Li Kan had clearly blocked the Qinglong Sword with a three-pointed two-edged sword, but he was not strong enough. The three-pointed sword was unstable and was directly knocked and rebounded on his shoulder armor. The Qinglong Sword only reduced its casting force and was deflected a little, and the direction was deflected a little, and it still chopped on Li Kan's shoulder with one knife.

Li Kan was chopped off one of his arms, and he fainted from pain when he was dismissed, but Guan Yu quickly made up for the second knife, ending his pain.

With Li Kan being killed by the formation, Cheng Yin, who was dozens of steps away, did not have the courage to come up and challenge, and ran back directly. Guan Yu chased more than a hundred steps, and the cavalry team chased and killed more than two hundred Han Sui's army before ordering him to retreat strictly to the camp.

The two armies separated and each breathed a sigh of relief.

Han Sui looked at the sky, then looked at the soldiers who were sweating profusely. He had to painfully give up the tactic of "using the enemy's weakness of carrying the water to destroy the morale of Guan Yu's army."

Han Sui ordered: "Forget it, let's take a break first! We will spend 50,000 people with Guan Yu and thousands of people bask in the sun and waste their energy. It's not cost-effective. Take advantage of the noon to build more door panels and hit wooden arrows to break the walls, and slowly destroy the fortifications, shoot arrows to fight again!"

Han Suijun quickly started eating, and then took a while to have lunch during the hot sun.

After sitting for a while, many soldiers took off their leather armor and even ran to the Yellow River, walked down the river beach, and directly scooped the river water with their hands to drink.

The Yellow River near Lanzhou has not passed through the Loess Plateau, so the river water is still clear. It is all the mountains and rivers brought by the Tao River from the northern slope of the Qinling Mountains, the snow water brought by the Huangshui River from the southern slope of the Qilian Mountains, or the snow water from the source of the snow mountains on the Qinghai-Tibet Plateau.

After resting at the hottest time at noon and hastily created some new wooden attack equipment, before the beginning, Han Suijun, Yang Qianwan and Song Jian made an appointment to launch a fierce attack together on three sides.

Moreover, this time they agreed on the style of wheel battles and batches. They did not ask the entire army to rush forward, but to ensure that the Guan Yu army never got a rest. After a long time, Guan Yu army's physical strength collapsed, and it would be completely destroyed.

...

At noon when the sun was scorching, in the empty place of the Yellow River Valley at the foot of the mountain, the Han, Yang and Song coalition forces were so dry that they doubted their lives in the newly harvested wheat fields.

In the steep and shaded place on Gaolan Mountain, Li Su set up a tent under several big trees to take a nap, with a smear of flowers and water on his body, and someone drove him mosquitoes. Of course, the clerks and war correspondents who accompanied him also had to take a nap.

This is early July of the lunar calendar! It’s such a hot day, why don’t you take a nap at noon?

Dian Wei stood outside the tent with expressionless face. The young and uneasy Wang Ping was restless. He went to a high bulging rock in front of the camp several times and climbed up with a telescope to observe the battle situation in the distant river.

After finally getting to the point of not being able to get to the point, Li Su woke up from a nap and drank some cold boiled water mixed with mint leaves to refresh himself. Wang Ping hurriedly went to ask for a fight:

"Right General! There are only 5,000 former generals, surrounded by 50,000 enemy troops by the Yellow River. They have been fighting for half a day. Should we rush down to rescue them and share the pressure of the former general?"

Wang Ping's attitude was as unsustainable as when Ma Su was surrounded in history.

But the difference is that in history, Ma Su was surrounded on the Nanshan south of Jieting, and Wang Ping's own small number of troops were camping on the way.

Now, Guan Yu is surrounded by a "road camping" position on the bank of the Yellow River, and Wang Ping himself follows Li Su on Gaolan Mountain, the "Nanshan Mountain of Jincheng".

Li Su didn't feel hot when she fell asleep, but when she woke up, she turned on the folding fan and slapped it a few times, reaching out her hand.

Wang Ping was ignorant and had not yet reacted and should have helped General Right to get up. Dian Wei saw that his eyes were good, and he had been following the bodyguard for many years. He came over and gently pushed Li Su's elbow, and Li Su stood up lightly without any effort.

Dian Wei's help shows that his grasp of strength is very comfortable. He will not hurt Li Su's arm, nor will it make Li Su feel numb after standing firmly.

Wang Ping couldn't help but feel a sensation of sympathy in his eyes.

That's right, it's just sympathy. He was "having the title of a high position of general from all directions in the court, he was so weak that he could not stand up with a carp."

There is no one else's weakness in this article.

Li Suhao had the time to pat the hem of her robe and asked, "Have the big flag in Yunchang Camp changed? Or the one in the morning?"

The camp on the mountain is more than ten miles away from the river. The naked eye cannot see the big flag clearly, even if the flag is several meters long. But with the help of a telescope, the good looking look can still see the general color of the flag clearly.

Wang Ping immediately replied: "It's still the same side in the morning."

Li Su used the back of his left hand holding the folding fan and patted his right hand in his heart:

"Isn't this going to end? It means that Yun Chang himself thinks he can still withstand it. Why are we anxious? Zijun, you are still too young and can't hold back. After all, you still have to learn in your early twentieth year.

We just want to continue to act like a threat without threat. When Han Sui was defeated, we would go straight to the south gate of Jincheng! Yun Chang used a catapult to attack for several days ago. The city defense of a poor place like Jincheng, such as the northwest, was not very strong.

If we rush through the broken parts, we should easily climb first. Han Sui's elite combat soldiers are all outside the city at that time. Once the old and weak guarding the city see a huge change, they will definitely have a great morale and lose sight of one thing. We have more important things to do."

Only then did Wang Ping convince him.

The 5,000 soldiers in Li Su's camp were relatively suitable for mountain warfare in this Western Expedition, and there were also many Qingqiang soldiers, so they walked on the Gaolan Mountain and flew like flat ground. Once the critical moment, the tiger would have to rush down the mountain and rush down, and the action could be ensured to be very fast.

It is really suitable to let Wang Ping, who is good at mountain warfare, take them to climb Fit to fight raids. As early as last year's Chang'an City Siege, Wang Ping had already brought those soldiers who are good at climbing Fit to attack the city, and had some experience.

Although he was frustrated at the beginning of the battle against Chang'an, the walls of Jincheng were much shorter than those of Chang'an. Chang'an was seven feet long, and the quality was only two feet long, and the quality was poor. Li Su was very relieved about Wang Ping.

The battle on the banks of the Yellow River in the distance never stopped completely. Li Su occasionally confirmed it with a telescope on the mountain, and secretly praised Guan Yu for his unmovedness.

After a long time, he finally heard a dull and tiny noise in the sky. Li Su focused his head and listened quietly, indicating that the people around him were quiet. After listening for a while, he was indeed unsurprisingly happy.

The sound of the surging Yellow River suddenly increased several times!

"The whole army is ready. Wang Ping and other floods rush to the Han Sui army. After rushing to the base of Jincheng City wall, you rush down the mountain. Once the flood peak passes, you can immediately climb the city to grab the city! Be sure not to let Han Sui's main force return to defense!"

Wang Ping had been holding it in for a long time, and immediately shouted and rushed down the mountain with thousands of mountain soldiers.

...

In the ferry camp on the bank of the Yellow River in the distance, when Guan Yu's army heard the rumbling sound of water, his morale was also greatly boosted.

"The whole army shrinks its defense! Gradually give up the battalion wall! Except for the posters on the post, the crossbows were withdrawn and moved to the car formation first! Soldiers at the high posts should not panic! Continue to block until the last moment! Give up the village wall in an orderly manner!"

Guan Yu ordered the front-line guards to retreat in an orderly manner. After all, when the flood came, he was still guarding the village wall, so it was possible that he would be washed away.

Anyone who has seen a flood knows that the impact of the flood is very strong. Even if the water depth is not enough to be over, as long as it reaches the depth of a person's chest, the impact of the rushing force can also drive people down and away.

Some of Han Sui's army were also in chaos because they also heard the sound of the flood and became at a loss, as if they had thought of some terrible possibility and ran around.

But not all soldiers have this sensitivity. These people are from the northwest and have never seen a flood in their lives. More people are just at a loss.

Han Sui narrowed his eyes, stared at the upstream direction for a while, cold sweat dripped in his ears, and then shouted: "Hurry up! Divide the troops back to the city!"

Unfortunately, no one below knew how to execute his orders in a hurry.

Especially the Di and Qiang soldiers who were fighting to the death of the camp wall at that time, when they saw Guan Yu's army retreating and retreating to the defense line of the car formation in the camp, they thought that they had really relied on their own efforts to force the enemy to give up the camp wall, and their morale was instantly bursting.

"Guan Yu's army was defeated! They gave up the village wall! All rushed! The baggage and property were in the village!" Yang Qianwan, the king of the Qiang Di, had never seen a flood in his life. He actually shouted like this and rushed in with his Di soldiers from his own tribe.

Especially dozens of iron-armored soldiers of the camp who cut off the rear of friendly forces and bought time for friendly forces to retreat into the chariot formation, blocked the camp gate until the last moment. Yang Qianwan was overjoyed and rushed forward, stabbed several soldiers of the camp behind the hall with a horse spear and one back stab to death, which made him feel overwhelmed.

Unfortunately, before he reached Guan Yu's car formation, the flood had already appeared in his sight, and soon he "boomed" to sweep his troops.

Yang Qianwan and Song Jian were originally the main attack on the east side, and they were rushed to the upper reaches earlier than Han Sui.

Yang Qianwan's horse failed to stand firm, and was pushed by Hong Feng and was directly knocked to the ground. Yang Qianwan's second half of the shouts of killing that had not finished shouting turned into "Gulugulugulugulugulugulugu".
