In ancient times, marching was a very complicated job, but it was not like games, just like the game, and there was a lot of work to do.

First, we must send a pond cavalry... This pond cavalry can be understood as a scout + a communication soldier, which is the task of exploring the enemy situation and reporting information during the march.

In the morning, the first trumpet sounded in the military camp, and each department had to pack up his belongings and uniforms, and then follow the orders to cook and eat.

The dry food and supplies were counted, and after the processing was completed, they did not set off. Instead, they sent a pond cavalry to investigate. The pond cavalry was organized by ponds, and there were five people in each pond. These five people should pay attention to looking at each other when investigating and not be separated from their respective perspectives.

Everyone is equipped with cannons so that they can call the army to the police when an emergency occurs.

When the army marched, regardless of how many troops were divided, each of them had to set up a pond cavalry. Each of them had twenty-four pond cavalry, each of which was one mile apart, and the scattered range could reach up to more than twenty miles.

It can be said that the Tangqi is the eyes and ears of the army.

Each of Li You's pond cavalry is equipped with a waist knife and a bow and arrow. As a communications soldier, there is also the most important flag. It is actually a flag gun. The gun is three meters long and a small flag thirty centimeters wide is placed under the tip of the gun.

If the Tang cavalry finds an enemy team, it will sway the flags from left to right. After seeing the Tang cavalry behind it, it will transmit information to the main general layer by layer.

If the enemy is still far away and does not encounter this situation suddenly, then you just need to slowly activate the flag. If the enemy's large army is aggressive, then you have to draw a circle and shake the flag.

If it is a terrain problem, such as having no way to go or being narrow in water, you don’t have to shake the flag and just pass it on orally.

In order to avoid the enemy expelling the Tang cavalry and the information is interrupted, the military law stipulates that the Tang cavalry cannot retreat all of them, but retreat according to the enemy's expulsion efforts.

For example, when the enemy's expulsion team approaches, the first one of the pond cavalry retreats to a mile and another one of the pond cavalry. The enemy comes back and retreats in turn. Then the pond cavalry returns to their original position, and then the enemy advances, and we retreat, and we advance, and each pond is carried out in turn.

Li You also formulated the colors of the flags according to modern rules. For example, if you encounter an enemy, you shake the red flag. If you find that the enemy shakes the yellow flag, there are many enemies shake the green flag, there are few people shake the white flag, and if you shake the black flag, you have their own uses, and you cannot be confused.

This can greatly improve the accuracy of the intelligence. In addition, Li You stipulated that the Tangqi obtains intelligence only to the main general. If the Tangqi returns to the battalion to report and investigate information, no matter whether it is important or not, the officers and soldiers along the way are not allowed to intercept and interrogate. They only need to go directly to the central army to report to the main general, and then the main general summons the officers of each department to discuss.

If someone dares to intercept Tangqi and interrogate the information in the middle of the journey, they will be handled by military law.

This is Li You's rigor and the essence of military strategy. Intelligence is the most important thing in a war and must not be leaked out. However, this is a plain, so you can use a pond cavalry.

After arriving in Lingnan, the role of Tangqi will not be so great. Everyone in Lingnan knows that mountains and rivers are steep and waterways are crisscrossing. There is no land to be hidden and no land to be intercepted.

So Li You decided that after Ruguilian arrived in Lingnan, he would merge with Tangqi. Whenever he encountered a steep mountain and could not go up to the cavalry, Ruguilian's soldiers would go up the mountain to explore with five-sided and five-colored flags. All valleys and dense forests should not be missed.

This is Li You's progress. Because of the first time to suppress the rebellion, Li You dare not be a little careless. Fortunately, there are Xue Rengui and Su Dingfang next to Li You. They are both handsome generals, and Li You don't need to worry too much about some basic things.

Just like the marching order of the army, Xue Rengui himself formulated a detailed and reasonable marching formation. The front troops were cavalrymen of various units. Because the cavalry was fast, they quickly advanced to two or three miles away from the camp after leaving the camp, and then stopped standing, set up a queue and began to be alert.

Then, the infantry units set out in order according to the distance and distance of the position, and arranged warnings on all sides twenty steps away from the camp.

Finally, the baggage team left the camp. After all the battalions were out of the camp, the order changed again. The infantry gathered their formation and walked in front of the cavalry, and then the cavalry guards led the baggage team to march two miles away from the infantry. If it was a heavy snow, the cavalry would step on the snow in front and open the road, and the infantry would follow behind.

The sixth brother Mei Qi who managed Li You's logistics was Mei Qi. Mei Qi had managed the logistics of a 100,000 army. In addition to the supplies and food... He also gave every soldier, noting that every soldier prepared two liters of fried yellow rice, one liter into crushed powder, and one liter packed with another; there was also one liter of five flour, of which five made into sesame oil steamed cakes, five made fried noodles soaked in soaked in soy wine, and five made fried noodles soaked in salt and vinegar. They were each wrapped and carried with them for emergencies.

This is not something that ordinary army or ordinary quarantine officers can do, because it is too expensive, but the chance of saving lives increases after spending money. With this food, even if a soldier is left behind, he can survive for a long time.

If you encounter obstacles from a river and there is no ship in the water, Li You also recruited a group of naval troops. The navy carried the thick ropes from the army to swim to the other side, and then the ropes were erected and fixed on both sides.

Then the soldiers cut down bamboo and wood, made rafts and placed them on ropes to make suspension bridges. If there were no trees nearby, they would use long spears as temporary materials, tied up and placed on the ropes, and then lay armor on them as road surface for emergency response.

In order to avoid being attacked by half a cross or the enemy ambush, after the suspension bridge is built, the entire river will not be crossed. Instead, the elite troops of the selection of the front line will be sent to cross the river first, and then the formation will be set up to guard and protect the troops crossing the river behind. Then, every time you pass by, you will occupy the favorable terrain and form a formation to cross the river in turn.

Hehe...Li You had already discussed any details and any way to deal with it in advance. In order to suppress the rebellion in Lingnan, Li You can be said to have made the most complete preparations.

During the march, if there is something to be done, it is necessary to suspend fortifications. In addition to setting up camps and laying out fortifications, beacon piers must be built one or two miles outside the camp as an open post warning.

When an enemy army came to attack the camp, they lit the beacon according to the number of people. Generally, ten people lit small torch fires, one hundred to two torch fires, three to four hundred torch fires, and five to one thousand torch fires, three torch fires, and then increase.

If the enemy comes to attack the camp and encounters strong wind and sand weather, and the visibility is low, then Li You will repeatedly instruct each unit to not allow each unit to go out to fight, mainly to avoid being blocked by wind and sand after leaving the camp, and being defeated by the enemy one by one with cavalry.

It is comprehensive and omnipresent.

"Ah...!" Li You sat in the carriage and stretched his waist. Now he had been out of Chang'an City for almost a day. The army is now led by Xue Rengui as the vanguard to open up the mountains and roads, and Su Dingfang as the logistics to stabilize the morale of the army.

Li You was guarding the central army, but there was not much work. Everything was going according to the steps, but Li You didn't know that in the Chang'an Palace, Li Shimin found a letter from Li Mingda, which said: Father, I am already in the fifth brother's army now, and I want to get my own things back. I made it clear that I would help you get a meeting to recruit prince consorts, and you will let me go to Lingnan.

But the fact is that Brother Wu is going to Lingnan, but you want to keep me together. I was very angry, so I chose to follow him secretly. My father should not look for me. If you want to force me back, I will go on a hunger strike. This time I am not talking about it, I will do what I say.

Then he drew the head of an angry little girl behind her. The little girl's head was Li Mingda at first sight. After seeing this letter, Li Shimin was a little panicked at the first time. He subconsciously prepared to issue an order to recall Li Mingda.

But when I think about what if I recall Li Mingda at this time and the little girl really fights against her hunger strike, what should I do? You must know that Li Shimin knows Li Mingda's personality very well, just like Empress Changsun. Although Empress Changsun's mother is in the world, her personality is very stubborn.

Take Changsun Wuji's case for example. No matter how Li Shimin explains it, Empress Changsun just doesn't want her brother to be a high-ranking official. You should know that during that time, Changsun Wuji really only became an overly small official, and Li Shimin did not dare to entrust important tasks.

From this you can see the stubbornness of Empress Changsun. If she brought Li Mingda back and Li Mingda really went on a hunger strike, then Li Shimin could only be at a loss, so she did not issue an order, but did not issue an order. How could she know Li Mingda's current situation?

As a last resort, Li Shimin did not dare to make the order, so he could only send Yang Qu to chase him. Yang Qu ran for a day and a night before chasing Li You.

"Your Highness..." Just as Li You was doing nothing, suddenly, Yaoyu came over from behind and said, "Your Highness, Official Yang is here..."

Li You said "cuff". At first, Li You felt that he had heard it wrong. Yang Neiguan came. You should know that Yang Qu is Li Shimin's close minister. How could he come here? And what he does here? Is it because Li Shimin wants to monitor him?

Li You frowned slightly, but even though he frowned, he still had to greet him immediately. But what Li You didn't expect was that after seeing Yang Qu, the news he received was something that made Li You frown even more by one person.

It turned out that Yang Qu came to find Li Mingda.

"What...? Did the whisper into my Hu Ben Guard?" Li You really didn't know what to say. After hearing Yang Qu's report, he immediately ordered the army to investigate suspicious figures, and even if he digs three feet into the ground, he would find Li Mingda.

After ordering for about half an hour, Li Mingda, Yan San, Di Renjie, Xiao Baoer, four guys were directly searched by Li You. These four guys had been hid in the baggage camp and hid in the carriage. If Yan San hadn't been too big, they might not have been able to find it.

"Your Highness the Princess..." Seeing Li Mingda dressed up as a soldier, Yang Qu hurriedly walked up and helped Li Mingda tidy up his clothes with distress.

However, Li Mingda shouted with anger: "If I don't go back, I will never go back. My fifth brother agreed to take me to Lingnan and I want to see my gold mine. My fifth brother lied to me. My fifth brother is a big liar."

With a frown, Li You was speechless, and the other party directly took his army.
