Passing through Zhuyang Pass, it is the boundary of Hanzhong, and the first city to bear the brunt is Fangling County.

The defenders of Fangling County were not many, less than 2,000 people.

The main reason is that Zhang Lu is now going all out to defeat Liu Zhang in central Sichuan, and in the eastern part of Hanzhong, he is mainly defensive.

If Zhang Lu also deployed heavy troops in Fangling County, Liu Jingzhou was only afraid that he would deploy more troops in Zhuyang Pass.

The arms race, this is a bit of a pit for Zhang Lu.

Therefore, the garrison arranged by Zhang Lu in Fangling County only has a number of soldiers and horses of less than two people, and they are all old, weak, sick and disabled.

Its main purpose is early warning.

If the Jingzhou soldiers want to enter Hanzhong, Fangling County must bear the brunt, which can warn the cities behind, and also win time for Shangyong, Xicheng and other cities to be defended. After all, Zhang Lu was in Shangyong City, but he still deployed 20,000 heavy soldiers.

In the early morning, the sky was about to brighten, and in a forest near ten miles of Fangling County, six thousand troops were resting in the forest.

In an open field, by the morning light, Zhuge Liang scolded Fang Xuan on a map.

"There are three important towns in Hanzhong, one of which is Nanzheng, the second is Xicheng, and the third is Shangyong."

"Nanzheng is the capital of Hanzhong and the base camp of Zhang Lu, with 30,000 elite soldiers stationed. This city is easy to defend and difficult to attack, and we can't beat Nanzheng City in a short time, so we won't care about it now. ”

"Xicheng, in the early Han Dynasty, was also the capital of Hanzhong County, yes, Xicheng is also a high city with deep pools and a strong city."

"Hanzhong is hilly and mountainous, Xicheng and Nanzheng are nearly 800 miles apart, there is only one road in between, and the road is dangerous and difficult to travel. Therefore, if we want to seize Hanzhong, we must first take Xicheng, and then we can defend Xicheng and block Zhang Lu's counterattack. ”

In his previous life, after Guan Yu lost Jingzhou, Meng Da, who was stationed in Shangyong, immediately jumped back.

(Note: Originally, Liu Feng and Meng Da were stationed in Shangyong, but after Guan Yu was defeated in Jingzhou, Liu Feng ran back to Shuzhong to ask for guilt, thinking that his father Liu Bei would not kill him, but he didn't expect to be corrected on the spot.) If so, Meng Da was dominant in Shangyong, and immediately jumped back. ）

At that time, Wei Yanzheng was ordered to garrison Hanzhong (Nanzheng), but he could only sit back and watch the anti-thief Meng Da sit big, why?

It's not that Meng Da has blocked Xicheng!

Between Xicheng and Nanzheng, the 800-mile mountain road seems to be a ravine, Nanzheng City is at the other end of the ravine, and Xicheng is at this end of the ravine. Sending troops from Nanzheng to Xicheng, the eight hundred miles of ravines and ravines are difficult to walk, not to mention, Xicheng happens to be at the exit.

If you don't uproot Xicheng, how can you attack Shangyong.

And Xicheng, blocked at the exit of the ravine, is not so easy to uproot.

Wei Yan tried to kill Meng Da several times, but he was blocked from the left of Xicheng.

So much so that when the original owner came out of Qishan Mountain, Meng Da was so big that he had 100,000 troops and directly established Xincheng County.

Therefore, only by taking Xicheng and blockading the west of Xicheng, several counties in the eastern part of Hanzhong can become a county on their own.

……

With Zhuge Liang's narration, everyone was looking at the map, leaning slightly, but Liu Bei said: "Although Kong Ming is a little good, but Xicheng is also five or six hundred miles away, and it is very difficult for us to sneak attack Xicheng." ”

As long as you capture Xicheng and hold on to this city, you can block Zhang Lu's counterattack.

Liu Bei naturally understands this.

But the problem is that even if there are not many garrisons in Xicheng, it is still a fortified city. With him Liu Bei now only 6,000 soldiers and horses, if he wants to storm Xicheng, it is undoubtedly a fate to seek fish. What's more, there is also the possibility of being dumplings made by Zhang Lu's army.

If you want to take Xicheng, you can only have a chance of winning by sneak attack.

However, in the case of sneak attacks, there are also problems.

From Fangling to Shangyong, and then to Xicheng, this road is already densely populated, even if he Liu Bei's army can avoid the sentinels along the way, he can't avoid the eyes of the people in Hanzhong, once the news leaks slightly, he Liu Bei is also the result of being dumplings.

"We're not going to attack Xicheng, but Shangyong!" Zhuge Liang said with a smile.

"There are 20,000 garrisons in Shangyong City, as long as we can sneak attack successfully, these 20,000 Zhang Lu troops will basically become prisoners."

"At that time, we will carry these 20,000 captives and march to the city of Xicheng, and then we can make a forced landing."

Can a captive soldier be used immediately?

Liu Bei, Guan Yu and others were a little incredulous.

Regardless of the morale of the captives, there must be many die-hard elements among them, who have not gone through a long period of training, transformation, and screening, and using prisoners is a double-edged sword, and if they don't hurt the enemy, they will be stabbed in the back.

The lesson of Xuzhou, but Yin Jian is not far away!

Liu Bei was about to refute it, but Pang Tong smiled and said, "Kong Ming's plan is good. ”

"After the 20,000 captives are dispersed, they will be reorganized, and our soldiers will serve as the commander and chief; It's not okay to fight, but it's no problem to pull to Xicheng City and put up a formation. There are only three or two thousand defenders in Xicheng, and they can't figure out our reality clearly, and when they see the formation of twenty or thirty thousand troops outside the city, they must be frightened. At that time, as long as there was a slight threat and temptation, Xicheng would inevitably surrender. ”

Sun Tzu's Art of War: Ten are to surround it, five to attack it, and multiple to divide it.

If you want to capture a fortified city, you can besiege it with ten times the number of troops, and you don't need to attack the city, and when the food and grass in the city are exhausted, you can naturally capture it. Of course, with ten times the number of troops besieging the city, most of the people in the city are panicking, and naturally there will be people who want to surrender.

And if five times the force is attacking the city, it can only be stormed, and the victory or defeat is only between five and five.

If it is one or two times the number of troops, it is necessary to find a way to divide the defenders of the city, otherwise it will not be able to break through.

With 20,000 prisoners and Liu Bei's 6,000 headquarters, this is nearly 30,000 troops.

The soldiers are coming to the city, Xicheng County doesn't know the reality of Uncle Liu Huang at all, and Xicheng County only has two or three thousand defenders, at that time, the city must be cold, even if the guards want to wait for help, but the small soldiers below, as well as the big households in the city, I am afraid that everyone will not be of the same mind.

At that time, as long as there is a little threat and temptation, someone will inevitably open the city gate and welcome Uncle Liu Huang into the city.

This is not a conspiracy, but a conspiracy.

……

After everyone figured it out, Zhuge Liang continued: "If you want to sneak attack Shangyong, you must first capture Fangling. ”

It is basically impossible for the army to bypass Fangling and sneak attack Shangyong.

This is not in the plains, there are roads everywhere, you can walk day and night, or you can choose other roads.

Hanzhong is already hilly and mountainous, there is only one road from Zhuyang Pass to Shangyong, and the rest of the places are mountains, and it is difficult for hunters to enter and exit, not to mention the army? And Fangling County is on this road, blocking the front of Shangyong City.

Therefore, if you want to sneak attack Shangyong, Fangling County is a hurdle that cannot be bypassed.

"There are only 1,500 old and weak defenders in Fangling County, and they will attack the city later, and they will almost be able to capture it in one go."

"The main problem now is that the news of the capture of Fangling County cannot be leaked."

"There are 20,000 garrisons in Shangyong City, and once the news leaks out, it will be particularly unfavorable for us to sneak attack Shangyong City."

Shangyong City is an important town in the east of Hanzhong, the city is high and the pond is deep, and there are 20,000 heavy soldiers stationed. Uncle Liu Huang now only has 6,000 soldiers and horses, most of which are still borrowed. Once Shangyong City is on guard, it will be even more difficult to conquer it.

At that time, Zhang Lu in Hanzhong will also react, waiting for Uncle Liu Huang and his Zhuge Liang will inevitably be disadvantageous.

Therefore, before the sneak attack on Shangyong, the news of Liu Beijun's invasion of the Hanzhong territory must not be leaked.

"General Zilong, when you attack Fangling County later, you will lead five hundred elite cavalry to serve as sentry cavalry to ensure that not even a fly can fly out within a radius of fifty miles from Fangling County."

The first task, Zhuge Liang gave it to Zhao Yun.

Zhang Fei was impatient and could not take on the important task of intercepting and killing the sentry cavalry. Guan Yu is arrogant, he has just come into contact, and he is afraid that he will not bow down to him Zhuge Liang. Elected, only Zhao Zilong, who works hard and complains, is worthy of the heavy responsibility.
