Chang'an City received the news that it was already on the fifth day of the Battle of Yunzhou, at this time the spring ploughing had begun twenty-five days, and it had basically entered the end, but the bustling and lively Suzaku Street was broken by a burst of fast horse military reports.

"The Northern Military News, Yunzhou is in an emergency." These are the words that people heard from the eight-hundred-mile urgent messenger.

For a while, Suzaku Street has exploded, how long has it been, Datang has finally settled down for a few years, why is there anyone who comes to commit it?

Why Yunzhou again? The Tang Dynasty took the grassland, and the territory expanded far to the north, why did the enemy come to Yunzhou to report urgently? Could it be that the military situation at the front is already uncontrollable?

In the palace, Li Er's hand holding the messenger's urgent report was trembling, how could this be? Can't hold it even if there is a thunderstorm? 50,000 cavalry swallowed? In this way, Yunzhou was lost five days ago? That Jingde and Niu Jinda will not ......

At this time, Li Jing, Bai Fan and others also hurried to the palace.

"Your Majesty, the matter is urgent, according to the military situation, Yunzhou must have been lost, as for the people and the defenders, we can't speculate, we can only calculate the worst." Li Jing, who was in military uniform, stepped forward and said.

Li Er regretted a little and muttered: "This matter is strange, if I let Jingde and Zhijie stick to the fight, there will be no such thing, even if the thunder is a failure, the defense should be more than enough." ”

Bai Fan shook his head and persuaded: "Your Majesty's words are wrong, Yunzhou's position, only the attacking side has a chance to retreat from the enemy, if it is defensive, it is categorically impossible to prevent, and no number of people can prevent it."

Unlike the three fortified cities in the north, there are walls on all sides, and it is enough to arrange for the defenders to hold on to the four sides.

Yunzhou is built close to the Great Wall, if the enemy wants to break through the Great Wall and enter the Central Plains, he will only face a city wall in Yunzhou, but not only Yunzhou can be selected, along both sides of the Great Wall, the endless city wall can be climbed by the enemy's ladder, so in any case, Yunzhou can not be defended.

It's just that I didn't expect that the enemy didn't divide his troops this time, and all 400,000 rushed to Yunzhou, which was not His Majesty's mistake. ”

"Yes, second brother, this is not the time to care about gains and losses, it is necessary to send troops to help quickly, it has been five days, I am afraid that the enemy has already hit Jinyang, that is 400,000 hungry wolves, every more moment will harm our people, and there can be no delay." Li Jiancheng said.

"Li Jing listens to orders!"

"The minister is here!"

"Send 200,000 troops to the north in the starry night, no matter what the life and death of Yunzhou City is, I want the enemy's 400,000 thieves to come and go!" Li Er gritted his teeth and said.

"Order, ten thousand deaths!" Li Er slapped the armor of his body with Bang Bang Xiang.

Turning to Bai Fan, he said, "The old man went directly to transfer troops to the battle, you go back and inform your aunt." ”

Bai Fan gave a military salute, "Nephew wishes my uncle a victory, and the Tang Dynasty will win!" ”

In the council hall, there was no martial arts, and they all shouted at the old handsome Li Jing for the victory of the Tang Dynasty.

Li Jing nodded, turned around and strode away, there was no flowery language, no point general sacrifice ceremony, established strategy, preparation for a long time, and the military situation could not be delayed, so old Li Jing knew that he was going to go on an expedition when he heard that he was in a hurry for eight hundred miles, and he came directly in armor, but he didn't expect that he didn't even have time to go home and give a notice.

In the council hall, Li Er opened his mouth and asked Bai Fandao: "Jian Zhi, you know the thunder best, the enemy actually found out that Ma Erpo was blocked, what do you think about this?" ”

Bai Fan laughed and said: "What is broken, the appearance of the thunder was not originally to use sound to deal with war horses, the enemy Western Turks have suffered big losses, and it is not uncommon for capable people to think of countermeasures."

The invention of the thunderbolt is to deal with the damage of its explosion, and to deal with foot soldiers, a good throw of a thunder can kill and injure four to ten enemies, and against cavalry, it can also kill at least two horsemen.

This artifact, the enemy is unknown at present, so it can't be broken, but our production speed is limited, the thunder is insufficient, the enemy has an army of 400,000, and we only have 100,000 thunders in the north, if there are 400,000 thunders in the north, are you afraid that they will block their ears? ”

Well, everyone was speechless, so it did make sense, it was indeed this truth, weapons and equipment crushed everything, I originally thought it was just an exaggeration, but now it seems that this thunder has verified this.

Chang'an angrily sent 200,000 troops to the north, and the 50,000 troops of Youzhou, which was closer on the other side, were also led by Cheng Yanjin to march west to aid Yunzhou two days ago.

Chai Shao and Cheng Yanjin analyzed the information of the herald soldiers and found that Yunzhou could not hold it, and it was too late for the 50,000 troops in Youzhou to rush to help, so they could only look all the way to the south of Yunzhou to see if they could join up with other reinforcements, without an army of 100,000, Datang would not be able to fight with the enemy's 300,000 or 400,000 people.

Therefore, Cheng Yanjin's march was not very fast, but the scouts sent hundreds of miles to prevent inadvertently crashing into the enemy's encirclement.

Besides, after Su Dingfang suggested retreating in Yunzhou on the same day, Niu Jinda and the two drove the people to retreat overnight, fortunately, Yunzhou was restored and rebuilt for a few years, after two bloody massacres, the current Yunzhou city is basically moved in later, and there are no aborigines who are difficult to leave their homeland, so the people responded after hearing the army's encouragement to flee south, and no one wanted to follow in the footsteps of the first two massacres.

It was just a city of 200,000 or 300,000 people, and the overnight action could not be silent no matter how secretive it was, so that night, the enemy army outside the city organized an overnight siege.

Wei Chigong and Niu Jin made a plan, and the plan was calculated to bring a golden cicada out of its shell, leaving two thousand elite bluffs to resist for a night, and the rest of the army retreated south with the people.

Of course, it is not with Liu Bei of the Three Kingdoms who retreated with the people, and the kind of hard work and delay is more than worth the loss, now at the time of the war, as long as you go out of Yunzhou, there is Datang land everywhere, and it is most convenient for the people to disperse, and the fear in your heart will naturally speed up, which is better than being escorted by someone, as for the slow action of a few people who are greedy for money, it can only be said that people die for money, and they don't blame anyone.

After attacking all night, the army outside the city listened to the constant sound of trumpets inside in the early morning, and had no choice but to retreat temporarily, so the remnants of the soldiers who stayed behind hastily buried the corpses of their comrades, left a row of empty flags, and rushed away through the south gate.

By the time Yuangai Suwen found out that the person opposite had gone to the empty building, it was already two hours later, and even if he was angry, it would be useless.

"The whole army searched Yunzhou, took all the goods as supplies, and the cavalry chased south, I don't believe how far they could run overnight." Yuan Gai Suwen said ruthlessly.

Mo Helu scolded secretly in his heart, this guy's military order is really ingenious, you foot soldiers stay to loot, let our cavalry chase and kill? What if there are traps? Is it easy for me to leave more than 80,000 cavalry?

Fortunately, Wei Chigong and Niu advanced and retreated quickly, and the Western Turkic cavalry did not dare to press too closely, so when they joined Li Daoyan from Jinyang two days later, the army behind them had not yet caught up.

And the convergence of 20,000 people in Jinyang, plus the remaining 10,000 people in Yunzhou, a total of 3,000 people, including 10,000 cavalry, can also implement Su Dingfang's guerrilla plan, otherwise, if the troops are insufficient, and they are all foot soldiers, even if you want to guerrilla, I am afraid that you will not be able to do it, after all, you can't outrun tens of thousands of cavalry on the grassland.
