Cao Cao still cares about Liu Zhang. Pen fun and pavilion www.biquge.info

"Back to the lord, according to the latest news received, Liu Zhang has not returned to Chengdu yet, and according to the distance, he should not have arrived now. However, Xu Shu should have returned to Chengdu, but the latest news has not yet arrived. Jia Xu replied.

"I don't know what's going on in Chengdu." Lao Cao muttered to himself, as if he was more worried about the situation in Chengdu than Liu Zhang. After thinking about it, he asked again, "Is there any news from the Western Regions?" Are there any anomalies in Hanzhong and Liangzhou? ”

"It is reported that Pang Long had just won another great victory in Chigu Castle not long ago, completely annihilating the 100,000 allied troops of Wusun Xiaokunmi and Kangju, and the feudal domains were shaken, and there was no more rebellion, and I heard that they had begun to go west with all their might, and began to open up the westbound trade route. Liangzhou's Fa Zheng is still working on Liu Zhang's settlement plan, and Zhang Renbu in Liangzhou is also fully cooperating, and now there are often Liu Zhang's flying troops and even new troops in the entire grassland. Li Hui and Li Yan in Hanzhong have some abnormal movements, but they are in the direction of Shangyong, which means that they are aimed at Jingzhou, and they should be instructed from the direction of Chengdu. Jia Xu replied briefly.

"Pang Long's second victory in Chigu? Can you elaborate on what a big victory was and how it was fought? Xun You asked.

It is reported that after Liu Zhang left, he appointed Pang Long as the governor of the Western Regions, Shi Dai, as the state pastor, and had full authority to handle the affairs of the Western Regions. Pang Long took Liu Zhang's urgent return to Hanzhong as an introduction, spread rumors everywhere that the Han army was going to withdraw, lured the coalition army of Wusun Xiaokunmi and Kangju, and recaptured Chigu City in a sneak attack, but as soon as he recaptured, Pang Long was surrounded and blocked in Chigu City, and then the 100,000 army was completely annihilated. Jia Xu introduced the general process to everyone.

When everyone listened, they were almost dumbfounded.

How can this battle be fought like this?

He actually ceded the city to the enemy, and then surrounded the city outside, annihilating 100,000 of the enemy's elites.

Liu Zhangjun only had a few people in the Western Regions, but there were only 13,000 people.

How dare you fight like this?

After a while, Guo Jiacai said: "Actually, a few years ago, Liu Zhang wanted to fight like this, but Pang Long just gave full play to some of Liu Zhang's ideas on the art of war." ”

"How so? Bonghyo, how can you think so? Cao Cao asked.

"Do you still remember the Battle of Gaoping when Liu Zhang first sent troops to Liangzhou a few years ago? At that time, Liu Zhang, with less than 10,000 people, faced the hundreds of thousands of Xiongnu troops in Gaoping, and Liu Zhang opened the city gate, in fact, he wanted to put the enemy army into the city. Liu Zhang's tactics at that time had a lot in common with Pang Long's World War II Chigu. They all wanted to put the enemy army into the city. The main force of Liu Zhang's army was infantry, while most of the enemy were cavalry. After the cavalry entered the city, the mobility was greatly lost, and Liu Zhang's crossbow arrows were sharp and long-ranged, as long as the four gates were killed with crossbow arrows outside, the entire city would become a natural encirclement, so that the enemy army would be trapped alive. Especially Liu Zhangjun now has a weapon like a crossbow, once the enemy army is trapped in the city, it will be a dead end. If it was outside, Liu Zhang's army was mostly infantry, and it would be difficult to surround the enemy regiments and achieve such a total annihilation. Guo Jia explained.

"Bonghyo is right. In fact, the year before last, Zhang Renbu besieged Han Sui, and the tactics used were similar to those used by Pang Long in World War II Chigu, Zhang Renbu was the camp of Han Sui who was besieged at that time, and Pang Long was besieged Chigu City. It seems that if our army confronts Liu Zhangjun in the future, we must be careful of Liu Zhangjun's tactics. Xun You added.

Everyone was silent when they heard this.

Originally, the city was built to defend against enemy attacks, but now the city has become its own cage and tomb.

If that's the case, then why waste so much effort to build the city?

If that's the case, then why do you need a city wall?

"The two gentlemen said this, and now they understand a little bit about what open city construction Liu Zhang is engaged in in Shuzhong, as well as open city defense." Cao Cao seemed to have an understanding.

"In fact, when Zhong Xuan attacked Hanzhong, he also suffered a loss from Liu Zhang's tactics like this. Liu Zhang fully brought his weapon superiority and the characteristics of the army into full play. Guo Jiadao.

Several of Cao Cao's strategists were okay, although they were also surprised to hear Liu Zhangjun's tactics, but the touch was not so big, but Cao Cao's generals didn't slow down for a long time.

"The last general is very curious, Pang Long is only more than 10,000 people, how can he surround the big city of hundreds of thousands of people?" Cao Chun asked.

"It's simple. They besieged the city, and they didn't even need 10,000 men. During the year, Liu Zhang's troops were divided into two routes, one to besiege Guishan City in Dawan and the other to Chigu City in Wusun, and the strength of the siege on both sides was only five or six thousand. In fact, it is very simple, that is, to block the city gates on all sides with a step/crossbow, and then use rangers to wander around the outside of the city, so that whether you want to break through the city gate or want to hang down from the city wall and slip away, you will be easily hunted, and you will not use much troops at all. Jia Xu explained.

Guo Jia followed: "Yes, a few tread/crossbows can block a city gate and block a city, and it doesn't take many people at all. ”

"Lord, there are a few gentlemen, if you say so, then we and Liu Zhangjun will not be able to fight in the future, even if their city is not defended, we will not dare to enter, and our city will not dare to let them surround it, if this is the case, then what else to fight, there is no way to fight at all." Xiahoudun immediately shouted.

"Now you should understand why Lao Tzu failed so badly." Xiahou Yuan said fiercely.

"That's why I've always been at ease with Guanzhong." Cao Cao said: "However, three years ago, since Pang Longqi attacked Chang'an, Yuan Chang and Ang'er have learned a lesson, and now Guanzhong is also taking measures to defend the enemy outside the city gate and extend the defense line as much as possible." ”

"I've seen Ang Gongzi's city defense design, and it's still a little different from Liu Zhangjun. Ang Gongzi used more outposts outside the city to build sentry checkpoints and sentry This is still very different from Liu Zhang's kind of defense, where there are no defenders in the city and the defenders are all outside the city. Xun Yu said.

"In fact, everyone misunderstood, the cities under Liu Zhang's rule are not completely defenseless, but some important cities are very well defended, such as Hanzhong and Chengdu. There were garrisons on all sides of their city, and the sentry posts of these garrisons themselves were far away, and a large number of enemies would surely be discovered early on. As for the small group of enemies in disguise, it is likely that they will not even be able to deal with the guards in his city. Moreover, there are secret passages inside and outside the city, and once the enemy situation is discovered, the important institutions of the government will soon be transferred outside the city, and even if you enter the city, it will be in vain to occupy the official office. Like the last time Zhong Wei attacked Hanzhong, this time Zhao Wei rebelled in Chengdu, all the same. Only when you destroy the garrison outside his city can the city be considered truly yours. Therefore, his open defense is actually a very tight form of defense. This kind of is currently only suitable for Liu Zhangjun, like we can't imitate it now. ”

"Bonghyo is right. In fact, don't be fooled by the open defense that Liu Zhang said, you just need to treat the guards in the city as soldiers. In fact, in my opinion, Liu Zhang divided the army into two kinds, one is his current new army, which is specially responsible for mobile operations, and the other is the guard captain, who is responsible for local law and order, anti-theft and banditry, and its own combat power is actually not bad. In general, when encountering an attack by a small group of infiltrating enemies, the guards in the city can resist the delay for a while. You can think of his lieutenant as a local troop. Xun You explained again.

"Having said so much, then I still say that if our army fights with Liu Zhang's army, there is still no way to fight, the siege city does not dare to attack, and the city cannot be defended?" Cao Hong asked dissatisfied. (To be continued.) )
