Li Mengxi asked how many prisoners had escaped, but Liu Bei couldn't answer for a while.

Liu Bei persuaded Li Mengxi to go and rest first. It was too late at night, so Li Mengxi shook his head.

"There are serious deficiencies in the army." Li Mengxi raised his eyebrows.

Liu, Guan, and Zhang looked over instantly.

Li Mengxi thought to himself and said, "Earlier in Wen'an County, Xuande Gong and I borrowed the city to train troops. At that time, we were discussing the methods of defending the city. One of the tactics of defending the city was to divide the battlements, and one team would defend one battlement. The enemy troops from other places would board the city.

There is no need for others to rush to rescue you.

Just in case, in order to save someone else, the person will finish his journey in an instant, leaving his own place empty.

If you press the gourd and lift the ladle, the tiger will have left the mountain before the enemy arrives, which is very wrong.

Therefore, when defending the city, one team and one battlement should guard each one with due diligence, and should not leave lightly."

"Tonight, I hit the target of [the enemy has not arrived, the tiger has left the mountain] mistake." Li Mengxi said in a deep voice.

"I don't know whether the prisoners fled from the east or the west.

However, due to the disturbance of the prisoners, the patrol team hurriedly gathered in one place. If they were gathered in the east, then the north, south, west, and west would be empty. If they were gathered in the west, the north, south, east, and west would be empty.

If the enemy uses a strategy of attacking from east to west on a certain day and feigns an attack in the east late at night, when we are guarding the camp on all four sides, they will all rush to the east, leaving the remaining three directions empty. If the main force is hidden in the south, and when my guards leave,

Wouldn't it be great if he suddenly came to kill you?"

After Li Mengxi finished speaking, Liu, Guan, and Zhang fell into deep thought.

It was indeed a big problem. Liu, Guan, and Zhang only paid attention to why the prisoners ran away, but did not pay attention to the movements of the patrol team for the time being.

As soon as Li Mengxi said this, Liu Guanzhang realized the problem.

Liu Bei frowned and pondered for a long time, then pondered, "We can imitate the strategy of defending the city. When defending the city, one team should guard one stack and not leave lightly.

During the night watch, you can also guard one door at a time, and do not leave it lightly.

When I heard there was a disturbance at the east gate, I was not allowed to move lightly at the west gate.

If there is chaos in the south, there will be no movement in the north.

Night guarding is similar to guarding a city. They are both royal guards and their tactics are similar." Liu Bei thought thoughtfully.

Liu Bei is very knowledgeable and can sum up the general internal relationship between night defense and city defense, which are both defenses.

This is what Li Mengxi is good at, and Liu Bei has gradually begun to move towards new heights of summary and deduction.

The escape of the prisoners tonight exposed the great deficiencies of night patrols and defenses, but once the problem is exposed, the problem is not big. Just add a night defense order, which stipulates that those guarding the east gate should guard the east gate, and those guarding the west gate should be killed.

No matter how loud the sound, there will be no movement without orders.

The remaining three doors remain the same.

"Besides that, there are..." Li Mengxi said again. He looked up at Liu, Guan, and Zhang and asked, "Have the prisoners been recovered?"

Liu Bei said, "I chased him very far, but I didn't catch anyone."

Li Mengxi nodded, "That's the problem."

"I dare to ask Xuande Gong, General Guan, and the three generals. It's dark everywhere at night. Should they chase them out?"

"Why not?" Zhang Fei glared.

Guan Yu frowned.

Liu Bei opened his mouth but said nothing.

Zhang Fei said that if the prisoner escaped, he must be chased.

Li Mengxi smiled and asked Zhang Fei, "May I ask the third general, how far do you have to chase a prisoner?"

"Chase till now." Zhang Fei replied without thinking.

"Well, if the three generals advance with little force and bump into the Yellow Turban army, the Yellow Turbans will unleash thousands of arrows, and the generals may be in serious danger."

Zhang Fei didn't like what he heard and said to himself that if he really bumped into the Yellow Turban, why was it that he, the Yellow Turban, could shoot me first, instead of me taking advantage of his unpreparedness and destroying his camp in one go?

Although Zhang Fei doesn't like to use his brain, he is not stupid.

Zhang Fei thought for a moment and understood.

When marching at night, you must not be able to see far away. If the enemy is ambushing a certain place, you will not be able to see it even if you approach, making it very easy to be ambushed.

Zhang Fei scratched his beard, his eyes widened, and he looked thoughtful, "Hey, according to what you said, Xiao Meng, you can't go out of the camp to chase people at night."

"Exactly." Li Mengxi nodded, "It only takes two to three hundred steps to catch up."

"Not only did the prisoners escape and cannot be pursued, but if one day the enemy attacked me at night, and then they were unable to attack me, they retreated in defeat.

At this time, if I pursue you, I will never be able to get far.

I don't know whether it was false to attack at night and true to lure me out of the stronghold.

If I fall into the trap and lead my fine cavalry to chase and kill me, if I am ambushed, all my fine cavalry will be lost.

If a general in the army chases him out, he will lose the general.

Going out at night to chase the enemy will only bring small benefits but huge harm, so do not do it.

It was pitch dark at night. Even if we pursued him, the enemy would scatter in all directions. Ten of us could not see one of them, so the pursuit was very ineffective.

Therefore, you must not go far away at night."

Li Mengxi summarized it this way.

Thinking of Gan Ning's feat of defeating the camp with a hundred cavalry, Cao Cao's camp was thrown into chaos.

Cao Cao suffered a big loss. When he realized what he was doing, he restrained his generals and prevented them from pursuing him.

Cao Cao was well versed in military strategy and knew that if he pursued Wu Jun again, he would suffer even greater losses if there was an ambush on the road.

The darkness at night is a natural disadvantage. If you are prepared or unprepared, the attacking party will inevitably take great risks.

This is the second point, the omission discovered by Li Mengxi.

There is a third point.

Li Mengxi asked strangely, "If you want to chase deserters, why don't you see cavalry chasing them?"

Guan Yu said, "The cavalry does not keep vigil at night."

Li Mengxi understood, cavalry is valuable, right?

The cavalry can play a relatively large role, so it is okay to save the cavalry's physical strength as much as possible and not to let the cavalry do any work or less.

According to the weight, if there is work, priority will be given to the infantry, and priority will be given to the spearmen in the infantry.

Because the spearmen fought in formations, even if they lost a lot of physical strength, as long as they could handle the guns and formed a good formation, they could still play their due role.

If there is any work, let the spearmen do it first, then the sword and shield soldiers.

The reason why sword and shield soldiers are ranked after spear soldiers is because sword and shield soldiers have to rely on physical strength to fight. Whether they hold a shield to collide with the enemy's shield soldiers, or hold a shield and hit the enemy's formation, it requires physical strength.

When the shield soldiers fight, it is also a brutal hand-to-hand fight that requires even more physical strength.

Therefore, the loss of strength of the spearman will not affect the combat effectiveness of the spearman very much, but if the sword and shield soldier loses strength, the combat effectiveness will be sharply reduced.

After the platoon of sword and shield soldiers, there should be the crossbowmen. Bending a bow and shooting arrows is extremely energy-consuming. If the crossbowmen are exhausted due to work, and a battle suddenly starts, the crossbowmen will become weak after being unable to fire two archers, and the crossbow troops will be exhausted.

Wasted.

The last of the uncle-like arms is the cavalry.

The order of doing the work is exactly the opposite of the weight of the arms.

Gunmen have no human rights.

The soldiers patrolling the camp at night are all infantry, which is a little inappropriate.

Take tonight's case of prisoners escaping at night. If there were one or two teams of cavalry on standby, they would chase after them wherever there was any movement.

The cavalry was extremely fast, but the infantry could not catch up with the person and ran away. If there were any cavalry on horseback, they would not be able to escape.

Furthermore, if the enemy sends troops to attack us at night, and then they are unable to attack us and are defeated, we should pursue them a little further. When the enemy is defeated and retreated, it is a good time to kill people.

If the enemy is an infantry and comes for a sneak attack, I send the infantry to chase. The infantry chases the infantry and cannot catch up slowly. At most, they can shoot arrows aimlessly and hit a few people. If the enemy is a cavalry and come for a sneak attack, the other

When they retreated, I sent infantry to pursue them, but they were even less able to catch up.

And if we send cavalry, the enemy will be infantry, and the infantry will not be able to escape quickly. If we pursue two teams of cavalry, we can catch up in a moment, and then pursue them for a while. At least, the enemy will leave dozens or hundreds of corpses.

The enemy is cavalry, and the cavalry can escape quickly. If I send the cavalry to chase, I may bite the enemy's tail and shoot down three or five of the cavalry.

Therefore, when guarding the camp at night, fewer cavalry must be left to guard the camp at night.

The current army is not large in size, but in the future, if there is an army of 100,000, the camp will be several miles long.

At this time, if there is an enemy situation in any corner, the commander must be reported immediately, and the infantry must run. It takes a long time to arrive, but the cavalry can quickly convey the order.

Therefore, night patrol regulations need to be optimized and cavalry need to be retained to join the patrol team.

Li Mengxi was awakened by the messy sounds in the middle of the night, and after figuring out what happened, these were the problems he realized.

First, there is the issue of patrol team coordination. Each team is responsible for its own patrol area.
