Chenggu County, less than 50 miles away from the capital Nanzhengcheng, is the gateway to the eastern part of the capital of Hanzhong.

The geographical location of Hanzhong County is unique, and there is a small plain within a radius of 100 miles from South Zhengcheng. It is surrounded by mountains, and as long as the country is closed, it is the land of bliss where the princes are drunk and dreaming of death. In ancient times, before the Chengdu and Du Plains were not developed by the Chinese people, this place in Hanzhong was the legendary land of abundance.

Today, there are exactly four gateways around the capital Nanzheng City.

To the north, the main road guarding the mountains and valleys of the Qinling Mountains is Baozhong City. To the west, it is the Baishui Pass, which guards the pass in and out of Sichuan and Shu, and after the Baishui Pass, about two hundred miles, it is the Jiameng Pass where Zhang Lu once fought with Liu Zhang.

To the south, it is Wuxiang County. Well, at this time, this county has not been renamed Wuxiang, but is called Cangshan County.

On the left of Cangshan County, there is the Cangshan Mountain Range, and on the right is the Daba Mountain Range, and in the gap between the two mountain ranges, there is a narrow passage in and out of Ba County. Cangshan County, on the other hand, guards the main traffic routes in and out of Ba County.

The eastern gateway of Hanzhong County is actually Chenggu County.

Of course, after Xicheng, Shangyong and other cities were merged into Hanzhong County, many times, Shangyong City also served as the eastern gateway of Hanzhong County.

It's just that Shangyong City is too far away, and sometimes it's a bit out of reach.

For example, during the Republic of China, Shanghai was the eastern gateway of Nanjing, but when it came to the Great War, Zhenjiang, which was actually the closest to Nanjing, became the eastern gateway barrier of Nanjing.

In the same way, when Nanzheng City was attacked by troops, Chenggu City was the eastern gateway to the capital.

Liu Bei and Zhuge Liang led an army of 50,000 troops, and when they walked out of the 800-mile mountain road, the first thing they had to take was Chenggu City. Guan Yu and Zhao Yun led more than 3,000 light cavalry, which could bypass Chenggu City and directly attack the southern Zheng City; But if the 50,000 infantry army wants to bypass Chenggu, it is impossible. It's not that the defenders of the Hanzhong army in Chengcheng Gucheng dare to go out of the city to intercept or anything; The key is the issue of the food channel.

The 50,000 troops eat and chew every day, and the amount of grain and grass consumed is inevitably not small, and the grain and grass carried by the army cannot be too much, which needs to be continuously transported to the front line from Xicheng County in the rear.

In this way, there will be a small problem, and Chenggu City will be like a nail, blocking the grain road.

If this nail is not removed, the grain channel may be cut off at any time.

In this case, how can Zhuge Junshi endure it?

Therefore, after the 50,000 troops walked out of the 800-mile mountain road, the first thing was to come to Chenggu City and prepare to attack the city.

……

In Chenggu City, there were only 3,000 defenders.

At the beginning, Zhang Lu counterattacked Xicheng County, taking away almost all the troops in the hinterland of Hanzhong, and among the four gates of Nanzheng City, there were only less than 5,000 old, weak, sick and disabled defenders left.

Who would have thought that Zhang Lu was defeated in Xicheng County, and when he set out on the expedition, the 100,000 army did not survive when he fled back?

In order to hold Nanzheng City, after Zhang Lu returned, he shrank his troops as soon as possible. Almost all the troops in the four gateway cities were withdrawn, and the capital Nanzheng City was concentrated.

Only Chenggu, because it was the gateway to block Liu Beijun's westward advance, Zhang Lu still left 3,000 defenders.

As for the 3,000 defenders, how much can they do, Zhang Lu didn't do anything to hope.

"Big brother, my brother only takes the headquarters, and he can take this city for his eldest brother in half an hour!"

Under Chenggu City, in front of the battle, Zhang Feihu roared and let out big words.

With only 5,000 soldiers, Chenggu was captured in half an hour?

Zhuge Liang heard Zhang Fei's impatience, so he could only say hehe.

When Liu Bei heard this, he also shook his head with a smile, and then looked at Zhuge Liang. Zhuge Liang was sitting in the carriage, and the serious injuries in his body could not be healed in a short period of time.

On the carriage, Zhuge Liang also smiled and said: "The three generals don't need to worry, in an hour, Chenggu County will surrender!" ”

When the 50,000 army arrived at Chenggu City, they were originally going to set up camp, but Zhuge Liang did not arrange it that way.

Zhuge Liang directly asked the army to rest under the city, only to wait for an hour, either after the city was broken, the army entered the city, or after the defenders in the city surrendered, the army entered the city to receive the city.

"Lord, military advisor, do you want the last general to enter the city to persuade him to surrender?"

Yang Ren was also in front of the battle, looking at Chenggu City, and when he heard the military advisor say that he was not in a hurry, he was a little anxious to show his merits. As long as you can persuade the defenders of Chengcheng to surrender and let the main soldiers take the gate of the capital of Hanzhong without blood, isn't this a great achievement?

Among the 50,000 troops, there were more than 10,000 surrendered troops in Shangyong City, so the general Yang Ren also needed to follow.

Of course, Yang Ren at this time can no longer be said to be a demote. Zhang Ludu is about to be destroyed, and he, a general who saw the opportunity early, can only be said to have chosen a good bird to perch on a long time.

The other person, Yang Bai, stayed in Xicheng County and waited for the dispatch of Pang Tong, the division of the right army.

Zhuge Liang also shook the feather fan and said with a smile: "General Yang also doesn't need to be in a hurry to show his merits. ”

"Now that the general trend of Hanzhong is in the hands of the lord, we no longer need to risk the envoy being beheaded and send an envoy into the city to persuade him to surrender."

"But they persecuted them, and they had to surrender!"

Chenggu City is also a fortified city, but the defenders in the city are only 3,000 old, weak, sick and disabled. With an army of 50,000 to attack it, it will be possible to break the city in one day at most, Liu Bei is very clear about this, Zhuge Liang is also very clear, but the defenders in the city are also clear.

Of course, forcibly attacking the city, at this time, is also the next strategy.

Zhuge Liang has at least ten ways to take this city without blood, so why bother to forcibly attack the city in one fell swoop?

……

After appeasing Zhang Fei and Yang Ren, Zhuge Liang looked at Wen Shuo and asked, "Can the trebuchet be assembled in half an hour?" ”

The refurbled catapult after Pang Tong was refitted, and the whole assembly was naturally not suitable for long-distance carrying, but the disassembled parts could be transported long-distance by horse-drawn carts, and the left and right were just carrying dozens of more carts of materials.

The heavy task of carrying and assembling the trebuchet can now only be entrusted to Wenshuo.

A Pangtun brand trebuchet, assembled from the parts, before and after at most a sincere time.

This power-enhanced version of the trebuchet doesn't need much, and ten crosses are enough to force it into a stubborn one that will surrender.

Wen Shuo looked behind him, and the soldiers of the Thunderbolt Battalion under his command were stepping up to assemble trebuchets, and several of them were almost assembled. Wen Shuo felt that it would be perfectly fine to assemble one or twenty trebuchets in half an hour.

"Rest assured, after half an hour, our army's trebuchet will definitely be able to show its might!"

Wen Shuo rode on his war horse and replied quite confidently.

With the refurbishment machine modified by Pang Tong, Uncle Liu Huang saw a battalion alone, and the one who was in charge of the trebuchet was the Thunderbolt battalion. This Thunderbolt battalion is usually in charge of Pang Tong, and only in wartime, it will be temporarily assigned to a certain general to lead.
