Nothing new.

Ash Naqing's troops can be said to be Li You's private troops, that is, the Tang Army in the true sense.

Murong Ling's army is different, they are Tuyuhun's army, and Li You is reluctant to invest in them.

However, for the sake of friendly forces, it is also necessary to improve their tactical level.

In the following days, Li You explained the cavalry tactics of Yue Fei, Yuan Chonghuan and Dolgon to Hou Junji and other generals, and introduced some cavalry tactics in Europe.

The generals were amazed by the wealth of knowledge of His Royal Highness King Qi.

However, this is only a public lecture. Privately, Li You focused on explaining Genghis Khan's cavalry tactics to the generals of the Tang Army.

Genghis Khan's cavalry tactics were particularly well suited to terrain like the steppes and the Gobi. It can play an important role in the next operation in the Western Regions.

Li You focused on the existing cavalry tactics of the Tang Army, and found that there was a big gap between them and Genghis Khan's cavalry tactics in terms of tactical thinking and tactical level.

Li You explained the results of the later generations to Genghis Khan's cavalry tactics research to Hou Junji, Gao Yong and others.

Hou Junji and others were greatly inspired by Genghis Khan's advanced cavalry tactics. They really didn't know where His Royal Highness the King of Qi learned such profound cavalry tactics.

For such a bullish prince, everyone has only one word: admiration!

Immediately, Hou Junji organized the cavalry of the Tang Army and practiced the cavalry tactics he had just learned.

In the blink of an eye, it has been a month since Li You and the others arrived at Yumen Pass.

On this day, Xue Rengui, Wang San and Zhou Qing came to Yumen Pass with a special operations team. They brought Li You valuable letters from Hamid and Zhang.

Hamid's Persian army had already recruited 17,000 men, and due to financial constraints, he intended to halt recruitment for the time being and devote great efforts to training the existing personnel. Zhang Guigui, along with his father's righteous sons and other Tang Army veterans, is helping Hamid train his troops.

Since the Persian troops had not yet been trained, Hamid's army did not participate in this attack on Gaochang.

Next, Li You, Hou Junji and others visited the training performance of the special operations brigade, and Li You was basically satisfied.

Then I was waiting for news from Wang Xuance.

On December 25, Wang Xuance sent someone to bring the news.

Wang Xuance and Desire Valley set an agreement, the Tang Dynasty to support Desire Valley set 200,000 quintals of grain, scheduled to launch a mutiny on February 12 next year, after the fact, the Tang Dynasty canonized Desire Valley as the Western Turk Khan, only nominally submitted to the Tang Dynasty, not to pay tribute to the Tang Dynasty.

The Tang army also launched a simultaneous attack on Gaochang on February 12 to contain the army of the current Khan.

When they heard this, they were in high spirits and waited for the troops to be dispatched.

That night, Hou Junji came to Li You, and he said worriedly: "Your Highness, is this Desire Valley set reliable?" If he is given food and he does not mutiny, then you will not be able to tell, this is an act of financing the enemy.

Also, if the Desire Valley is unreliable, we will send troops to Gaochang, and the Turks will send troops to intervene, and we will be in trouble. ”

His fears were justified. In the previous article, Li You is suspected of being an enemy and is very risky. The latter is even more risky.

In history, Hou Junji attacked Gaochang and led all the Tang troops, with a total of 200,000 people. There are only more than 30,000 soldiers and horses in front of him, and he is still a miscellaneous army, and Hou Junji is really not sure.

Gaochang has about 50,000 inhabitants and 5,000 cavalrymen, mainly Han (mainly descendants of the Han and Wei Tunshu soldiers and civilians and immigrants from the interior who fled the war), supplemented by ethnic minorities (mainly Zhaowu Jiu surname and expatriates from other Western Regions countries). The Gaochang State system, such as the official system, the military system, the enlistment system, the scholar system, etc., is similar to the Han Dynasty.

Historically, Hou Junji led an army of 200,000 people to attack Gaochang, mainly to prevent the intervention of the Western Turks. If you want to fight Gaochang alone, he is sure that he will gather 10,000 people for Hou Jun.

Li Tai smiled: "Don't worry, Desire Valley will not change." "He is sure that the historical Desire Valley will launch a mutiny without foreign aid, let alone with foreign aid from the Tang Dynasty.

When Hou Junji saw that Li You was so sure, he no longer had any doubts, and began to prepare for the attack on Gaochang.

Why did Li You rush to fight Gaochang? Is it full of food? Of course not.

Gaochang is located in the north and south of the sky, is an important pass on the silk road, for the Tang Dynasty to open up the Western Regions and Central Asia, has an important strategic position. And, of course, cotton. In addition to this, there is another important reason.

In 630, the king of Gaochang, Lu Wentai, brought his queen to Chang'an, expressing his intention to submit to the Tang Dynasty, and was warmly received by Li Shimin, Taizong of the Tang Dynasty. The queen was also given the surname Li and canonized as Princess Changle.

From 633 onwards, when the Western Turks became stronger, Lu Wentai threw himself into the Western Turks, and from then on he no longer submitted to the Tang Dynasty.

Lu Wentai also joined forces with the Western Turks to attack Yiwu, Yanqi and other places that were vassal states of the Tang Dynasty at that time. Yanqi sent people to Chang'an to complain to Li Shimin.

Li Shimin sent Li Daoyu of the Ministry of Rites to ask about the crime, saying: "In the past few years, Gaochang has not paid tribute to my Tang Dynasty, and has not practiced the etiquette of vassals.

With the support of the Turks, Lu Wentai also spoke eloquently: "The eagle flies in the sky, the chicken nests in the grass, the cat plays in the hall, and the rat chews and eats in the cave, each has its own place, can't it be allowed to develop itself?" Obviously, the central government of the Tang Dynasty was not taken into account.

Li Shimin also wanted to give Lu Wentai a chance to repent and reform, so that he could go to Chang'an to clarify the situation, but Lu Wentai "said that he was not sick", and his anti-Tang heart was clearly revealed.

Later, the Tang Dynasty had many problems of its own, and it could not take care of the affairs of the Western Regions for the time being, so Gaochang openly surrendered to the Western Turks.

Li Shimin and the high-level officials of the Tang Dynasty have been holding this breath, so Li You proposed to attack Gaochang, and they immediately agreed.

In addition to the above-mentioned reasons, Li You also has an important idea, he wants to temper his ability to command troops, and in the practice of war, make himself grow and grow stronger.

On this day, Li You held a military meeting to deploy troops. I want to chat with more like-minded people about "{?$article_title?} ", WeChat pays attention to "excellent reading literature", chatting about life, looking for confidants~
