Lu Chang, who was in Yuzhang City, also knew that his generals Xu Zhi and Song Hui were defeated and were fleeing to Yuzhang City. After Lu Chang sent out the army, he didn't care about their progress, and every day he traveled back and forth to convey the battle situation on the front line.

When he heard that the Sui army was attacked by an unknown army, Lu Chang was stunned, didn't he hear of other forces in this area?

This is not to blame Lu Chang, the history of the Sui Dynasty that he knows is also a general situation, there are many specific details, how can he know every detail.

Lu Chang's impression on his subordinates has always been that he has not missed anything, but this time he didn't count it, and he couldn't show it on his face.

However, Lu Chang reminded himself again and again in his heart that he must not get carried away because he knew a little bit about the historical process. After a thousand years, who knows how many things they don't know?

The course of history can be exploited, but not relied upon entirely. Yiqiē still relies on strength to speak, and developing and strengthening oneself is the guarantee of victory.

Although it failed to stop the enemy this time, it also sounded the alarm bell in Lu Chang's heart, and revised Lu Chang's future development strategy from the side. However, this sudden failure still made Lu Chang very unhappy.

Paralyzed, I didn't plan to destroy Suhu's army immediately, since you rushed to find death, okay, I will fulfill you.

The general was promoted, and Lu Chang dispatched troops.

"Xu Zhi and Song Hui's troops encountered an attack by an unknown army, resulting in the failure of this blockade. Can Chen Feng and Chen Hongcang be available? ”

"The end will be."

"Order the two of you to lead 200 cavalry each to meet Song Hui's headquarters, and ensure that they withdraw to Yuzhang City safely, there must be no mistake!"

"No, the last general will definitely complete the task."

The two generals Jiao and Chen were ordered to go and led the cavalry to meet Song Hui's department.

"Xin Wen, Gong Chen, Dong Ren, and Zhang Qiang are here?"

"The end will be."

"Order the four of you to lead 5,000 infantry each to defend Yuzhang City, note that the armored soldiers are allowed to have a maximum of half of them, and the rest of the soldiers must fight in the clothes of the people. A few days later, our army will encircle and annihilate Suhuer, the enemy army, under the city of Yuzhang, do you understand? ”

"Understood, the last general will take the order."

Yuzhangcheng dispatched troops to take back Song Hui's defeated army, and arranged the siege and annihilation of Suhuer's army.

Xu Zhi and Song Hui came back to hand over the order, and they were a little frustrated.

"The last general is incompetent, failed to effectively stop the pace of Suhur's army, and failed to live up to the general's expectations, please punish the general."

"Well, although this mission failed, it is excusable that it happened suddenly. The early combat strategy was completely correct, and the effect was good. It's just that there are loopholes in the vigilance, and the operation is ineffective. Lessons learned in the future must not be overlooked. ”

"No, General Xie taught."

That night, Xin Wen and other four generals and 20,000 troops were left in the city, and Lu Chang led 5,000 cavalry and the main force of the Xiaoguo army to leave Yuzhang City at night.

Since then, the four gates of Yuzhang City have been closed and ready for battle.

In fact, Lu Chang didn't care about Suhuer's 30,000 troops at all, and he could completely wipe out Suhuer's 30,000 troops halfway through the attack.

However, Lu Chang is not a reckless person, and he has a plan in his heart.

Towards October, Xiao Mo soon established the Liang Dynasty.

It is impossible for Lu Chang to alarm Xiao Mo at this time, nor can he let Xiao Mo find out the details of the Sui army. What's more, Lu Chang must let Su Hu'er understand the illusion of the Sui army, so that he can pass it on to Xiao Mo in time.

To achieve this, Suhur and his army must survive for a while in order to play their rightful role.

At this time, there were still four or five months before the Great Sui Emperor Yang Guang was killed by Yu Wenhua, and Lu Chang had this rhythm of time in his heart.

In the evening of the next day, the army led by Su Huer and Zhang Shan'an arrived outside the city of Yuzhang.

Previously, Su Huer had reported the defeat of the Sui army to Xiao Miao. Of course, he will not tell Xiao Mill about the part where he was attacked, but try to beautify himself to make this war more beautiful in order to obtain greater benefits.

By the way, he also informed Xiao Mian of Zhang Shan'an's defection, and hoped to be allowed to let Zhang Shanan fight with the army.

Outside the west gate of Yuzhang City, Su Huer and Zhang Shan'an rode forward and came to the front of the battle to watch the guards of Yuzhang City. I saw that there were only 1,000 soldiers in armor of the Sui army on one city wall, and the rest were all people.

Lu Chang left 20,000 troops in Yuzhang City, which were assigned to the four city walls, each guarded by at least 5,000 people. According to Lu Chang's explanation, no more than half of them were required to fight in armor, that is, 2,500 people.

As a result, Xin Wen and the others were even more exaggerated, and after some discussion, it was decided to arrange 2,000 guards on each wall, and only 1,000 soldiers to fight in armor, in order to more effectively confuse the enemy army.

This also has the advantage of saving an army of 3,000 men for mobility, and replenishing it wherever it is needed. It is also possible to take turns to fight, so that the soldiers are not too tired.

As a result, from the outside, there were only 4,000 Sui troops in the entire Yuzhang City.

Su Hu'er and Zhang Shan'an looked at the garrison on the city wall, and a thought immediately surged in their hearts: Nima, pull out some people to make up for it!

"General, it seems that the number of Sui troops in Yuzhang City is not much, there are only 1,000 troops on one wall, which means that there are only 4,000 troops in the city. With our 30,000 troops, this city will be broken sooner or later! ”

Actually, Zhang Shan'an didn't say that Su Hu'er also saw it, can he not know how many troops there are in the city?

"Although there are not many troops in the city, it does not mean that the number of Sui troops is small. They are to send troops to garrison the nearby cities in order to keep our army from attacking. ”

"General, then let's fight quickly, take Yuzhang City first, and then clean up one by one. An army of 30,000 is besieging on all sides, and I think it will take it in a few days. ”

This Zhang Shan'an took it for granted, how could it be as easy as he said to break through a city!

"No, you can't besiege it from all sides. I intend to adopt the tactic of encircling three and missing one, leaving a route for the Sui army to escape and shake their will. Moreover, the city was besieged on three sides, two of which were still feints, and only the west city was really attacked. 30,000 troops attacked a wall and gave them a big surprise, haha! ”

This Suhuer is very cunning, and I have to say that this siege strategy is still a bit technical.

"What a plan! The general is really clever. ”

"General Zhang, the city walls on the north and south sides have been handed over to you. Your army can go down to the village outside the two city walls, and put up more flags in the camp to confuse the Sui army. You don't have to storm the city when you attack it, just make a show, understand? ”

"General, Shan'an understands."

"Okay, that's it. Arrange for the army to camp and rest for the night, and tomorrow morning cut down wood to make siege equipment and prepare for the siege. ”

Zhang Shan'an led the troops to the north and south of the city, and Su Huer led an army of 30,000 to camp in Xi'an, and stationed soldiers and horses to rest.
