In the northern suburbs of Chai Village, the official army camp, Prime Minister Yuchi Dun was listening to the general's report in the tent. The enemy troops retreating south were now surrounded by the official cavalry in Chai Village. Chai Village was only one mile away from Chai Water, but the other party had no chance to cross the river and continue to move south.

The advantage of cavalry is that they move fast, and they have the final say in the face of the enemy, whether to fight or retreat. A small group of cavalry can calmly harass the infantry team of hundreds or even thousands of people.

The enemy, which was mainly infantry, had no chance of winning, and even could not move.

Yuchi Dun personally led his troops south and spread a large number of cavalry like a net. Dozens of cavalry and scouts divided into countless teams to spread in Xizhou and Guangzhou areas, exploring the movements and stills of various places clearly.

Based on the news that all parties gathered here, the enemy army that retreated south without success in attacking Song Ping was not alone. The other party had reinforcements from Guangcheng, but was haunted by the official cavalry halfway and could not go north, so the enemy army trapped in Chai Village is now alone.

According to the information confessed by the scout caught the tongue, Yuchi Dun learned that the actual number of this enemy army was about 10,000. Except for the young and strong people who transported food and grass with the army, the number of soldiers who could fight was about 7,000 or 8,000, of which there were about 2,000 cavalry.

The composition of the enemy was indeed mainly composed of the Hulin Army. In addition, some Huangzhou crossbowmen are now entrenched in Chai Village and camped in the outer area, setting up a high number of deer antlers on the outside, resisting horses, with the intention of resisting stubbornly.

It is called "staying and waiting for help".

"Prime Minister, according to the confessions of the prisoners, the dry food carried by the enemy should be able to last for nearly ten days. As for the water source, there are several wells in the village. Although the water quality is poor, it is still OK to hold on for a while."

"No one in the army claimed to be the King of Xiyang, nor did he see the banner of "Yuwen".

"According to the prisoner's confession, before the Hulin Army headed north, reinforcements arrived in Shannan. This time, the one who tried to pick up the Hulin Army should be this reinforcement. The total infantry and cavalry had about 7,000 troops."

"Seven thousand..." Yuchi Dun thought about it, seven thousand plus eight thousand, a total of 15,000 soldiers. Perhaps more troops would arrive in Guangcheng in the future. It seems that Yuwen used Guangcheng as the main attacking stronghold. He had previously judged that the other party was going to attack the east and west, but it was indeed wrong.

But it doesn't matter. Now he led 20,000 cavalry to the south. The opponent pretended to attack Song Ping but failed to succeed. The eight thousand war soldiers retreated to Chai Village. Don't think about going back. As for the remaining enemy troops, in front of his cavalry, there was only one who could guard Guangcheng.

If Yuwen's family had another main force to go out to Pingyang, Shenzhou to the west, it wouldn't matter. Although the official army surrounding Xuanhu was mainly infantry, its strength was tens of thousands, which was enough to confront the other side.

And his cavalry would have to return to Xuanhu for three days at most.

This is the advantage of cavalry. It moves fast and can concentrate troops to defeat the enemy troops that seem to be very dispersed one by one. The combat power formed by 20,000 cavalry is stronger than that of 100,000 infantry.

This is also the reason why the Southern Army failed repeatedly in the Northern Expedition over the past hundred years: without enough cavalry, it is impossible to cover the long food route. Once the food route is cut off, the soldiers on the front line will be in chaos and cannot even withdraw. They can only fight for their own battles and are surrounded by others, and finally defeated one by one.

Now, Yuchi Dun has absolute confidence to let the relatively short-lived Yuwen army suffer, turning the so-called thing into a futile joke.

The enemy troops trapped in Chai Village were now surrounded by his cavalry. All he had to do was to annihilate the enemy immediately, and then wipe out the reinforcements leaving Guangcheng north of the city, eliminating the threat Shouchun might face.

At that time, the external circumstances will be cut off and the enemy troops trapped in Xuanhu will be over sooner or later.

"Are you ready now?"

"Go back to Prime Minister, you're ready!"

......

In the early morning, the north wind was bitter, sand and stones were flying, and the world was dark. People in Chai Village were blinded by the wind and sand, and they could not see the movement of the wind direction clearly. There were less than three hundred steps north of Chai Village, and a large number of soldiers gathered in the area.

The Central Military Office set up a starting barrier to block the wind, Prime Minister Yuchi Dun sat upright and supervised the battle on the spot, while the soldiers who were already ready began to prepare for the attack.

They piled up countless collected hay branches into many hills, and then lit them one by one. With the help of the strong wind, the dry fire quickly started to burn. Seeing that the fire had become, someone threw the collected horse manure into the fire.

When the horse manure is neither dry nor wet, it will produce a very thick smoke and is mixed with a foul smell. This is a common tactic used by cavalry in the north. Before attacking, burning horse manure on the wind direction above the enemy's army can make the soldiers in the opponent's army cry.

Tens of thousands of cavalry, one man and two horses, produce a large amount of horse manure every day, which has become the best material for making pungent smog. It has a large amount of tubes, plus dry fire and strong north wind, and its effect will inevitably be more outstanding than before.

A large amount of horse manure was burning, and pungent smoke enveloped the downwind Chai Village. At the same time, the soldiers arranged the rush-made carts.

There are hundreds of carts, divided into series, as moving covers for soldiers approaching Chai Village. At this time, it should be sunrise, but the weather is harsh, with dark clouds and snow, it is still dark.

Hundreds of cavalrymen left the line and mobilized mounts with ponytails tied with branches to gallop back and forth, raising a large amount of dust. They were wrapped in the north wind and rushed to Chai Village hundreds of steps downward. Yuchi Dun looked at it with a thousand-mile mirror, but saw that Chai Village was now rolling in smoke, and only a few blurry black shadows appeared in the smoke.

In this extremely unfavorable situation of headwind, how do archers in Shiba Village shoot arrows?

When fighting, as the head coach, he most hopes to fight a downward battle, that is, his side is in the upper hand and the enemy is in the lower hand. Whether it is water or land, the role of the wind direction cannot be underestimated. Now, he has done it easily.

The army in the upper wind direction is leeward, and the archers' eyes will not be fascinated by the wind and sand, and the effective range of the arrows shot out is significantly increased due to the wind.

The army in the lower wind direction is facing the wind, and the soldiers' eyes will be fascinated by the wind and sand blowing from the upper wind direction, and the effective range of the arrows shot is reduced sharply due to the wind.

When the two armies fought, there were countless cases of reversal of the victory or defeat due to the reversal of the wind direction. Yuchi Dun now surrounded the enemy in a village. Although the camp that the opponent temporarily set up had already exceeded that of this small village, his own side had a large number of troops and could choose the direction of attack calmly.

Even if the southeast wind suddenly blew as the attack was fought, the official army could change the direction of the attack and continue to launch an attack in the upper direction, and the opponent could only suffer. No matter whether it was arson or splashing quicklime, any means related to the direction of the wind could be successful.

Do you still want to win such a headwind?

"Prime Minister, the soldiers are ready, please give an order!"
