In order to deal with the scattered small troops of the Huns, the strategy given by Gao Zheng was to mobilize the people, a beacon fire for ten miles, and once they saw the Hun cavalry, they immediately lit a beacon fire to ventilate the news. In the face of this turtle-like defense capability, if the Huns did not take it for a while, when they wanted to leave, the cavalry of the Yue cavalry battalion responsible for guarding the beacon tower had already roared and bitten them tightly, so whenever the Huns found a group of people lighting the beacon tower, they had no other way but to withdraw.

The long action beacon moved all the way to the west, driving the Hun cavalry deep into the west of the river, and the Hun cavalry heading west also gathered more and more, and the traces were much more obvious when there were more people, and the Northwest Army, which was responsible for meeting the enemy head-on, could send spies to find them in the east, so the cavalry of the Northwest Army began to take the initiative to engage the Hun cavalry. In the wilderness, the Hun cavalry, which was better at salvo fire, had the advantage of the Hun cavalry, but the Han army was stronger, and benefited from the white snow cloak that could be made, and the cavalry of the Han army was more elusive than the Huns' cavalry. In the face of the increasingly cunning 'hunters', in order to avoid being surrounded and annihilated by a large number of Han troops, the Hun cavalry could only choose to gather more and more, intending to reduce the advantage of the Han army by concentrating their forces. And in this way, in fact, it is the strategy of the Han army.

When the beacon line had already pushed through Jiuquan County, the Huns finally found a problem, except for the soldiers they lost on the way to the west, almost all the cavalry had gathered here.

As the beacon line became quieter and quieter, the soldiers of the Yue cavalry battalion also knew that the Huns had basically gathered in one place, so they made a key step to change the situation of the war, crossed the beacon line, and attacked the Huns with the soldiers of the Northwest Army.

After three days of pursuit, three cavalry armies and nearly 30,000 war horses gathered on this vast grassland. The Northwest Army was in the west, the Vietnamese cavalry battalion was in the east, and two cavalrymen dressed in white stepped on the thin snow, spreading out into a long charging line and standing on the top of the mountain.

The Hun cavalry under the hill kept strangling their restless war horses, and the wind and snow gradually increased, hitting the Hun cavalry wearing animal skin clothes, which had been thinly piled up into a layer, "Right Captain, what should we do now?" The Han army has been standing there for more than half an hour, there are many of them, we have to decide as soon as possible!"

The right lieutenant blew a breath of hot air and looked at both sides, "It's not that I don't want to break through, it's just that the mode of this Han army is too weird, it's obviously condescending, neither let go of arrows, nor charge, I'm afraid that there will be an ambush behind them, so I want to find a right direction to break through"

The subordinates didn't think so, "Right Captain, subordinates suggest going directly to the west, this wind and snow are getting bigger and bigger, if we don't break through immediately, the wind and snow will get bigger and bigger, and we can't leave if we want to" As soon as he finished speaking, the wind and snow became bigger again, blowing so that the Huns could hardly open their eyes.

Seeing this, the right lieutenant pulled out his saber, "Warriors of the Huns, charge west with me!"

Trembling and blowing the sound of horns, more than 8,000 Hun knights drew their sabers and let out a roar of charge, scattered throughout the length of the entire defense line, and directly charged the camp of the Han army.

Gongsun De, the chief general of the Northwest Army, raised his spear, "Brothers, the time has come to avenge our dead brothers in the Western Regions!" All the Northwest Army has learned from Wu Xu's mouth about the annihilation of the Northwest Army, such a blood feud has caused an uproar in this group of bloody soldiers, and everyone is holding their breath to find out these Huns, but these Huns have repeatedly avoided and not fighting.

Originally, the imperial court sent troops to assist, and they were not happy in their hearts, but this time they had to do so, because if they wanted to capture and kill these Huns with their own hands, it was not enough to rely on their little cavalry.

The charging speed of the Hun cavalry was not fast, because they were thinking of pursuing from the west, but what was blowing here at the moment was a strong northwest wind, and the wind and snow hindered the charging speed of the Hun army. But it became an excellent time for the Han army to charge. More than 10,000 Han cavalry rode the wind and snow, wrapped in white clothes, and rushed out of the wind and snow, and the merciless spear pierced the chest of the Hun cavalry who could not open it because of the strong wind: "This shot! is to avenge the death of the brothers in the northwest!"

For a time, the Han army was splashed with blood everywhere it went, after the first team of the Han army charged, the Huns were planning to the Han army was now in the downwind direction, just when the counterattack, the second team of the Han army had come, as a team of Han troops was very special, this team of Han troops were all armed with iron cables, connected to each other, they did not deliberately go to the guns to pick the Huns to show bravery, but were interspersed in the Huns, and the long iron chains ruthlessly swept the Huns one after another under the horse.

The right lieutenant found that the situation was not right, and it was not a way to entangle again, so it was better to flee first, "Withdraw! The whole army wants to retreat west!"

However, the iron chain had tripped most of the Hun cavalry, and the wind and snow seemed to increase, and the horses under the seat could not advance. In this way, the grassland scuffle finally broke out.

The captain of the Yue Cavalry Battalion pulled out his battle knife, "Brothers, the face of the Northwest Army has been enough, and it is time to show the strength of the most elite cavalry of our Han Dynasty, and the whole army will attack!"

Silently, at the sound of an order, the cavalry of the Yue Cavalry Battalion charged down from the hill, and in order to speed up, they tore off the cloak that had been draped on their bodies, revealing their lean armor!

The battle has been fighting from the afternoon to dusk, the wind and snow have not stopped for half a moment, after the bloody battle of 20,000 Han troops, the Han army beheaded 3,000 in this battle, captured 3,000, only 2,000 Huns were left because the wind and snow were too big, the Han army could not pursue, so they escaped by luck, on the white vast snow, but there was a piece of red, the hot blood melted the snow, all of which were telling the tragedy of this battle.

"Then General Gongsun, the last general will leave" The task of the Yue cavalry battalion has been completed, and cooperating with the Northwest Army to strangle the Xiongnu army is enough to bring supreme glory to their Yue cavalry battalion.

General Gongsun, who was assisted by the Yue Cavalry Battalion, also did not hesitate to praise: "This time the Northwest Army can cooperate with the Yue Cavalry Battalion, it is really an honor for the Northwest Army, and I hope to have the opportunity to cooperate with you again," Gongsun De said with a bow.

"It is also our honor to cooperate with the Northwest Army!" Farewell!" The captain turned his horse's head, picked up a cloak with his gun, hung it on his shoulder, raised his gun and shouted, "Yue Cavalry Battalion! Return to the division!"
