Li Su did not persuade Liu Bei in the end, "don't rashly attack the city to seize time when the weapons of siege are not fully prepared."

Wei Jie and Ju Jun provided the information that the Beigong Gate of Weiyang Palace and the Hengmen of Beicheng were destroyed. After all, the temptation is too great. If you don’t try it, you will directly seek stability. Maybe you will have a bad reputation among the ministers and ministers, "preserving your strength and hoping to sit down and watch Li Jue take the blame and harm."

War is the continuation of politics. Sometimes, even if you make more sacrifices in the military for the sake of political cards, there is no way to do so. A woman’s kindness cannot win the world.

Li Su finally made two comments before Liu Bei rested:

First of all, tomorrow's attack should be based on testing, pay attention to casualties, and see that the situation is incorrect at any time, you can change the plan and stop the loss in time.

The second point is to pay attention to the fact that if things are inconsistent during the attack, the main focus should be on reconnaissance battlefield intelligence and the auxiliary focus should be on killing and killing the enemy with vitality. Anyway, if you cannot capture the city, it is meaningless to kill a few more enemy soldiers at once and waste your lives more than one pair.

But if a soldier successfully climbed the city and was finally killed, he would take the opportunity to observe the situation in the inner city from a high position and repair the city gates destroyed by Wei Jie and Ju Jun's soldiers, and how much specific fortifications were deployed?" This information was clearly investigated to pave the way for subsequent combat.

Both of these points are scrupulous. Liu Bei of course followed the advice and directly asked Guan Yu to negotiate with Li Su in person to see how to integrate into specific tactics and issue them to grassroots generals one by one.

...

The next day, it was dawn and before dawn, Liu Bei's soldiers who got up in the middle of the night had enough food and drink. They prepared their troops for half an hour, and then launched a surprise attack at the fourth day of the fourth day.

The soldiers did not have pre-ignitions, nor did they have complicated siege weapons, only a few city hammers and a batch of flight ladders.

The production of flying ladders is very simple and can be made at any time. It can be made in half a day. This is also the only thing that any siege force who travels a long distance can take out anytime and anywhere.

The siege hammer was a scrupulous person after Zhao Yun's troops arrived in Chiyang, and he was careful and ordered his cavalry to split up their troops to speed up the construction. Zhao Yun knew that Liu Bei might use it as soon as he arrived.

But Zhao Yun could not build a counterweight catapult in advance because his cavalry was not equipped with professional craftsmen. The technical content of the counterweight catapult was much more difficult than that of a city hammer. On the other hand, it was also slow to build that thing. Even if Zhao Yun had to measure it in advance one or two days, he would not have time to build it for him.

Even though they knew that after the Northern Expedition was successful, the princes of Kanto would gradually learn to build such a powerful tool, Liu Bei's army still kept the technical blockade of this thing as much as possible.

As for suppressing the city head and observing the defense dynamics in the city, it is best to use a well railing truck. If Zhao Yun built this thing two days in advance, it would have been possible to create some small ones. But the problem is that the walls of Chang'an City are seven meters high and thick, and are the three highest city walls in the world that are as high as Luoyang and Meiwu.

The well railing car must be far higher than the city wall to peek at the back of such a high and thick city wall, which is more troublesome than the counterweight catapult. Even if it is piled up, the construction technology of this era may not be able to build a well railing car that can be pushed and walked. At most, it will only be a wooden tower with a fixed base, so it will have to be constructed on site under the city. If it cannot be built, it will be pushed over.

Li Su himself had a bad premonition about this battle, so he just got up in the middle of the night, drank and waited for news in the tent, and did not come to the front line in person.

Guan Yu supervised the battle, led Gao Shun and Wang Ping, E Shun and Meng Xin to kick off the battle. Guan Yu planned to use a camp of traps and some elite Han infantry as the main force to attack the city gate, and then used barbarians who were good at climbing lightly and climbing the city to take on the work of ants to share the attention of the enemy's troops.

Wang Ping's Banyan Man was wearing light shields and leather armor, responsible for the wall section on the left side of the city gate, and the Sou Bing and Kunming Yi were responsible for the right side.

The battle began soon, and Li Jue's army was mainly responsible for the defense of the northern city, which was mainly Li Ying and Li Jin. They immediately launched a firm resistance and fought with Guan Yu's soldiers - mainly because they were close to Weiyang Palace. Li Jue was not at ease with his Qiang, Hu and Xianbei people under him were responsible for the defense near the palace, for fear that these people would take the opportunity to plunder more objects in the palace.

For a moment, the sound of killing shook the sky and blood flowed into the wild.

The elite iron-armored infantry carried the horse-slaying sword, pushed the city hammer and swarmed into the door opening, smashing wildly, hitting the broken city gate, which had been temporarily strengthened, and became more and more shaky.

But the good times didn't last long. Just when the door was forced to open the crack, the soldiers saw that the back was filled with temporary debris and rammed earth, and even simple door-sticking knives with strong antlers. For a moment, the soldiers squeezed into the front door hole entered the cruel ground meat without any room for maneuver.

Li Jin was in charge of the Li Jue Army in the city, and his troops were not much less than the high surplus. After all, Li Jue also occupied the Chang'an Arsenal, and also had the family's assets left by Dong Zhuo, and he could still get thousands of pairs of iron armor.

Even compared to the number of iron armor, Li Juejun was more than Yuan Shu, and he was almost equal to Liu Bei. He was one of the richest warlords in the country in this field.

Both sides had iron armored soldiers blocked the mouth, and the horse-slashed swords and sharp axes and heavy hammers slashed each other wildly. The broken limbs and arms flew across. They died in the iron armor. It seemed that the surface of the corpse was intact, but in fact, there were many people who were severely hit and deflated.

However, such a fierce rush can be regarded as a test of several situations: First, Li Juejun did not have time to repair the Qianjin Gate that was completely destroyed by Ju Jun's retreat.

According to Ju Jun, before he broke through, he completely smashed and dismantled the iron chains, winches and other complex mechanical structures inside the wall holes of the iron gates and suspension bridges. These things require precise mechanism construction. Li Yijun's terrifying rule of law, relying on massacre to solve the internal surrender faction, will definitely not win over engineering and technical personnel, so these things cannot be repaired by spending time and manpower.

However, without the help of the gate, Li Jue still dug several trenches inside the north gate, filling the digging of soil and building rammed earth walls. So even if the door is broken, it will still be subject to layers of resistance, which is as miserable as falling into a jail.

After the fight reached a stalemate, the defenders on the city faced the initial surprise and their counterattack gradually became fierce.

Although they did not have hot oil, it was not popular to pour hot oil to defend the city in this era, at least the guards temporarily cooked dozens of pots of boiling water, and then poured it down along the edge of the city tower on the top of the city gate. The boiling water was not entirely water, some were sewage or even "gold juice", and there were a large number of dirty bacteria and viruses.

Iron armored soldiers rely on martial arts and shields to block them. They are not afraid of swords or even wood rolling, but they cannot defend against boiling water when they are sprinkled. The iron armor has good thermal conductivity. Pouring boiling water on their bodies is even more miserable than soldiers wearing only leather armor and are more injured.

Even Gao Shun, who was personally supervising the charge and blocking the door, was accidentally splashed by boiling water and had to end up hurting. Fortunately, he was very skilled in martial arts and thick armor, so he was not injured by dirt and viruses, but was burned by the heat conduction of the iron armor.

But after retreating, when Li Su inspected the losses, he also asked all the splashed soldiers to immediately clean the Wei River water after cooking. As for generals like Gao Shun, they also applied precious distilled liquor to treat the scalds, just in case, of course these are all later stories.

On the front battlefield, with Gao Shun's temporary setback, Wang Pingban Man, the two wings, the mountain soldiers of the Kunming Yi, and the sou soldiers also suffered a lot of damage to the city. But Wang Ping was a brave man among the Banban Man, and now he was only eighteen years old. He was young and vigorous, so he led his men to the city wall for a while.

Unfortunately, the support was not good, and the ladder was pushed down more and more, and the position at the front of the city could not be expanded in the future. Li Jue's army rushed over like a tide, especially Gao Shun was injured and retreated. The soldiers in the door tunnel suffered heavy losses, allowing Li Jue's army to free up all their strength to deal with the enemy soldiers on the city wall. Of course, Wang Ping could not withstand, and in the end he had to retreat.

Fortunately, Wang Ping is good at mountain warfare and climbing, and can escape from the city walls and survive. If someone climbs slowly or dares to take advantage of the momentum to leap down when the ladder falls, he will probably fall to death directly when he retreats.

...

The fierce bloody battle lasted for half an hour. At the fifth day of the morning, as the sky was getting dark, Liu Bei knew that it was impossible to do something and could only retreat.

Because he was a surprise attack in the night battle, in order to prevent the army from moving too much, and the trampling of each other without torches, he did not invest much of the first batch of siege troops.

When Guan Yu was dispatched at the fourth update, there were less than 10,000 vanguard troops. The rest were on standby. After the breakthrough was made in the front, the vision was better before all could be devoted.

It is now dawn, and there is no progress in both directions, and there is no need for the rear army to invest.

Liu Bei's heart was bleeding, and he decisively expressed his withdrawal of troops temporarily, and to attack again after the escort, and prepare heavy siege weapons.

After the troops were withdrawn, the number of people was nearly 2,000 people killed and injured in this fierce battle alone, of which 300 or 400 were killed and injured in the iron armored soldiers. They were all frustrated when they were snatching the door, and more than half were burned, and Gao Shun himself was also injured.

The barbarian soldiers with light armored ants were even more injured, and the proportion of fatal injuries was higher, with a total of 1,500 people. Among them, 600 were killed and injured by Banyan Man, 900 were killed and 900 were killed by the sou soldiers and Kunming Yi.

Li Su was just right next to comfort Liu Bei, and at the same time comforted Guan Yu who had just retired: "The king, Yun Chang, built a large number of catapults and a fixed well railing tower. With the large number of people in our army, it will be delayed by more than five or six days at most. I know you are worried that Li Jue will be so crazy. If he occupys more than one day, the people in Chang'an City will suffer more than one day.

But the preparations were still unhurried. Fortunately, in today's battle, he discovered the virtual and realities of Li Jue's defense, as well as his morale, and also found out how much damage loopholes in the city defense fortifications left by Wei Jie and Ju Jun were available. I think that any part that Li Jue has not yet been repaired can't be repaired even if he gives him five days.

Moreover, since we have time to prepare, our army must take advantage of the number of people. According to Gongda, pretending to know that the North Gate is difficult to attack, we will instead build equipment outside the three gates in the east and south. Especially for building those sill-shaped observatory buildings that cannot be moved, which are more than ten meters high. In this way, we will definitely dilute the deployment of the defensive forces of Li Juejun-

The reason why I couldn't attack today was because Li Jue knew that the North Gate was destroyed and our army might attack the North Gate, so the reserve team stayed too much. Maybe it was Li Ru who helped him design the defensive deployment. We lost once, so that the enemy could see that our army was "retreat in the face of difficulties", which may not be a good thing."

Liu Bei sighed: "I can't bear it anymore, I'll listen to Boya this time. Alas, the temptation of opportunity is right in front of me, and it can make all the officials in Chang'an suffer less. I can't help it."

Seeing that Liu Bei accepted it, Li Su hurriedly looked around and talked about him, further alleviating Liu Bei's embarrassment: "In five or six days, Li Jue can't harm much. The people he wanted to kill were almost the same as before, and he would not slaughter every day.

Now that I have time, let the soldiers build equipment, the king should take time to see His Majesty and go to Huayin to ask for advice. After all, this is the most important thing to attack Chang'an. Even if Li Jue has done his best to do anything, he should ask for an order."

Liu Bei: "What Boya said is, please contact me first. If your Majesty wants to see me, you can meet in Huayin."

Even if Liu Bei wanted to go to Tongguan to meet Liu Xie, Liu Xie probably wouldn't dare to let Liu Bei's escort troops enter the pass. If Liu Bei was asked to go to the pass alone and only bring a few bodyguards into the pass, Liu Bei probably refused. So in the end, he should have just been outside Tongguan Pass, more than a hundred steps under the wall. Liu Xie led the ceremonial guards led by Dong Cheng to meet Liu Bei and determine the merits and demerits.
