Beigong Yuejia has been a general for generations, and he himself is similar to Kojiqiu, who grew up in the army since he was a child, and is proficient in tactics and brave.

When he was the earliest, he was in the southeast of Longzhou, fighting with Ran Xing and Pu Qin, who were of the same clan as him, and later because of his military exploits, he was promoted to the protector of Liupin, and was transferred to Dunhuang to protect the trade routes of the Western Regions, and began to fight with Rouran.

A few years ago, because he repelled Rouran's invasion of Dunhuang, he was promoted again, and he was appointed as the general of Wupin, Ning Yuan, and changed the town to Xihai.

After counting his battles with Ran Xing, Pu Qin and Rouran in the past, he was almost undefeated, and he was actually a member of the Dingxi Kingdom.

It is probably because of this record that five days ago, Beigong Yue fell into Rouran's ambush.

At that time, there was a Rouran army, about three or four hundred horsemen, harassing the east bank of Juyanze.

Hu Mu on the east coast asked Xihai County for help.

Xihai County Shou Duya suggested that Beigong Yue should wait for the reinforcements from Jiankang County to arrive before making a plan.

Beigong Yue disagreed, and said to Du Ya: "If it is a soft elite, so you should fight calmly, a little mongrel slave horse, why wait for Jiankang reinforcements?" The government guards the city, and I will break it. The prince can wait for my good news, and he will arrive in three days. ”

"Hybrid slave cavalry" refers to the hundreds of rouran cavalry.

After the Xianbei people went south to the Central Plains and founded the country, Rouran took the opportunity to rise, and over the years, they annexed the east and the west, and conquered many Hu tribes in Mobei. The hundreds of Hu cavalry that infested the eastern shore of the West Sea were from one of Rouran's affiliated tribes.

This tribe is called Eile, the history of the origin of the clan is very long, can be traced back to the Xia Shang time of the ghost Fang, and then called Di Li, the Warring States of Qin, called Ding Ling; Nowadays, in addition to the name of Eile, it is also called a high car by the Xianbei people.

Rouran's social development is already very backward, and the tribes they conquered have a level of science and technology, military and other aspects.

Beigong Yue has experienced a hundred battles, and the three thousand cavalry under his command are all Tang and Hu Dare soldiers who have followed him for a long time. He didn't even bring more soldiers and horses, but only led 200 elite horsemen, and then went out of the camp to fight.

Unexpectedly, these hundreds of cavalry were the bait of Rouran.

Seeing that Beigong Yue was coming, the cavalry retreated while fighting, and introduced Beigong Yue into the desert east of the West Sea. Rouran laid an ambush here with two thousand riders. Beigong Yue was caught off guard. Fortunately, he was fierce, and the 200 cavalry under his subordinates were also elite, fighting bloodily for half a day, and they actually broke out of the encirclement and captured one of the "adults" of Rouran's troops on the battlefield.

However, his ministry also suffered heavy losses.

When he returned to the city, only about 80 of the 200 elite horsemen remained.

Interrogating the captive Rouran overnight, he got a startling piece of news.

Beigong Yue previously judged that the scale of Rouran's southern invasion this time might not be small, but his judgment was still conservative, not to mention that it was not small!

In order to facilitate the rule, Rouran's power has expanded dramatically, basically occupying Mobei, and in order to facilitate its rule, it divides the territory into east and west, each with the royal family of the Yujiulu clan out of the town, and the western part of Longbei is adjacent to it.

Most of the people who plundered the border lands such as the West Sea before were individual or multiple tribes of Rouran in the west.

The confession of the captured Lord Rouran, this time is different from the past, and the same as the last time they invaded Dunhuang on a large scale, it was personally organized by the town commander of Rouran in the west, and up to now, more than 20,000 horsemen have been recruited, and all of them will go south in a few days.

This time to set up an ambush for Beigong Yue, it was a prelude to their southward movement, but it was because of the prestige of Beigong Yue, because of the fact that the town commander of the western Rouran adopted the strategy of his mastermind, hoping that he could kill Beigong Yue first through a strategy.

The reinforcements led by Koji Qiu, Lan Baozhang, Zhang Gui and others arrived in Xihai County the next day after Beigong Yue tortured the information, and after hearing the news, after discussion, everyone thought that if Rouran really had more than 20,000 horsemen to invade the south this time, it would definitely not be enough to defend the county alone.

Therefore, they urgently reported to Jiankang.

The content of the military newspaper sent to Jiankang is divided into two parts.

In the first half, he talked about the defeat of the ambush in Beigong Yuezhong and the large-scale invasion of Rouran.

The second half is the analysis of Zhang Gui, Koji Qiu and others.

Xin Er watched carefully.

Zhang Gui and others wrote in the military newspaper that there were no natural disasters in Rouran last year, there were no unexpected losses to their livestock, and life was completely surviving, so it is expected that they would not invade the south on a large scale for no reason.

Combined with the fact that their organizational methods for this invasion of Dunhuang were the same as the last time, they were all personally led by the town commander of Rouran in the west, so it was judged that the purpose of the Rouran people's southern invasion should still be for the Western Regions.

It is estimated that the town commander of Rouran in the west wanted to take advantage of the "civil strife" in Dingxi, and the opportunity of Hufeng's usurpation of the throne not long ago and the foundation was not yet stable, to make another attempt to interrupt the connection between Longzhou and the Western Regions, so as to bring the Western Regions under control and seize wealth.

And why didn't they fight Dunhuang first this time? Thinking that he had learned the lesson of being attacked by the West Sea last time and causing failure, he changed his strategy and attacked the West Sea first, and then Dunhuang.

The judgment of Zhang Gui and others is very correct.

The town marshal of Western Rouran is exactly this idea.

What Zhang Gu and the others didn't know was that the reason why the town commander of the western Rouran repeatedly conspired in the Western Regions was to compete for the position of Khan.

"Khan", which means "heaven", is a common title among the Donghu tribes, used to address the tribal chief. Unlike the Xianbei people, who also belonged to Donghu, after the Xianbei people dominated Mobei, they used the title of the supreme ruler of the alien Huns, that is, "Shan Yu", while Rouran used the idiom of the Donghu people and made "Khan" the name of their supreme ruler.

The founding of the country is still short, and all aspects are in an extremely backward state, called the country, there are not even a few official positions, and there is no writing, and even "carved wood for remembering" they don't know how to, the chief records the number of people, the generals' method of remembering the number of soldiers, is to use sheep to remember, a grain of sheep represents a number of people, soldiers, ten pieces of sheep and how many people, soldiers, and so on.

For such a "state", war is equivalent to a "way of labor", an important channel for them to obtain wealth, and at the same time, it is also an important means for their "chieftain", "lord", "town marshal", and "khan" to unite the hearts of the tribesmen.

The current Rouran Khan is the son of the previous Khan, and like Linghu Feng, he also usurped the throne, and since he ascended the throne, he has done a lot of unspeakable things.

Rouran had a "lord", for Rouran to break through the Mobei tribes made a great contribution, this usurping khan not only did not respect him, but actually raped his young wife with one of his fathers, and later killed this "lord".

There are so many things like this, and there are really a lot of them, which makes everyone in the country resentful.

The town commander of the western Rouran saw an opportunity, because of the intention of competing for the position.

If you want to compete for the throne, you first need to get the support of your tribes; And if you want to gain the support of your tribes, the best way is to control the Western Regions, so as to give your subordinates enough benefits.

Therefore, a few years ago, the town commander of Rouran in the west invaded Dunhuang on a large scale, but failed, and made a comeback this year.

The calculations of the western Rouran town marshal, Zhang Gui and others don't know, and Xin Er doesn't know.

But these are irrelevant, as long as it is deduced that Rouran's purpose this time is still the Western Regions, it is enough.

It can be judged that this southern invasion of Rouran will be something that has not been seen for several years, and it involves the safety of the trade routes in the Western Regions, and the stakes are significant, and it is by no means a trivial matter, but it still needs to be reported.

Xin Er immediately wrote the book and sent someone to send it to the royal capital urgently.

On the day the military sent away, Xin Er summoned Yang Fu, Yan Xi and other generals and officers, told them about the incident, and said to them: "I expect that the lord's reply order will soon arrive in the county, I have asked Ying, personally aid Xihai, you are ready to open at any time." ”

When Kojiqiu went north, he didn't bring Zhang Jingwei.

Xin Er sent an order to Zhang Jingwei, telling him to be ready to lead his troops to follow and help.

The military situation is like fire, and Linghu's reply order is really fast, which is completely different from the last time.

Two days later, in the evening, Xin Er received the will.

Linghu Feng attached great importance to this matter, and ordered Xin Er to "supervise the soldiers of Jiankang and Jiuquan counties and the Fuyi Protector Hu Cai, that is, to aid the West Sea", and said that "depending on the situation of the captives, if the troops are not supported, Lone will give you reinforcements again, so as to ensure that the West Sea is not lost, and the trade route of the Western Regions cannot be blocked."

There is not much land suitable for farming in Longzhou, and the population is also small, and the finance and taxation of the Western Regions trade road is a very important income of the Dingxi Kingdom, and if the trade road is cut off, the finances of the imperial court will suffer a lot of losses.

Xin Er then went to pick up another one for the Dan.

It took two days to transfer troops, and when Zhang Jingwei and his troops arrived, Xin Er entrusted the county affairs and Song Pian, and led the headquarters, Fu Qiaojun soldiers, and Zhang Buhu to go to the West Sea; Passing through Jiuquan, Fan Dan personally led the troops and joined the team. A total of six thousand foot riders. On this day, we arrived in the West Sea.
