Chapter 40: Those who know me, Brother Cao

"That is, General Cao has already engaged Li Guo." Zhang Xuan said.

"Exactly." Zheng Lian said: "The news that Xia Guan got is that yesterday, General Cao first sent Zhang Xianbi to the north of the Ming army. ”

"The Ming army made the Yueyang army attack it."

"General Zhang defeated the Ming army."

"Li Guo sent Niu Wancai, the general of the loyal battalion, to fight."

"There is no difference between the two sides."

"Li Guo sent someone to make a detour."

"General Cao sent cavalry to guard the flanks, and the army arrived early."

Li Guo held his weight and did not fight, and the two sides confronted each other. Each of them collected his troops. ”

At night, General Cao approached the Ming army to stand up, and the night fire on both sides burned in the sky. I was almost sleepless all night, and it was only after the third watch that I settled down. ”

Zhang Xuan sighed and said, "Those who know me, Brother Cao." ”

Zhang Xuan and Cao Zongyu are too familiar with each other.

Familiar, the most intimate partner, many things do not need to communicate, and each other can guess each other's behavior.

Cao Zongyu took the initiative to attack the Ming army, and the so-called was not to defeat the loyal battalion.

Rather, it dragged the loyalist battalion.

Defeating the Loyal Battalion and holding it down are two different concepts.

First of all, Cao Zongyu knew that his strength was not enough.

Chengling Mountain and Yueyang City cannot come out of the city empty, which is different from before, and Cao Zongyu's troops add up to only thirty or forty thousand people, except for the men and horses stationed in the rear, even if Zhang Xianbi's own troops are added.

Nor is it enough to compare with the Loyalty Battalion.

The reason why he had so much courage to provoke the enemy with weak troops was because he believed that Zhang Xuan would arrive soon. Just within these three days.

And although he is weaker than the enemy, he is also confident that within three or five years, Li Guo will not be able to swallow him.

Cao Zongyu pinned almost his net worth and life, the life and death of tens of thousands of troops, on Zhang Xuan.

How does this not make Zhang Xuan sigh: "Those who know me, Brother Cao." ”

This kind of friendship that trusts each other, understands each other, and can be said to be no worse than love.

Zhang Xuan said: "Did you send someone to contact Brother Cao?" ”

Zheng Lian said: "Someone has been sent." It is expected that General Cao has now been contacted. ”

Zhang Xuan said: "The herald departments are ready to dock. ”

Zheng Lian said: "But it should be like the battle of the Miluo River? ”

When Deng He and others attacked He Tengjiao, they went ashore far away and sneaked for dozens of miles to sneak attack He Tengjiao.

It turns out that such a means is very practical.

"Nope." Zhang Xuan said: "In this battle, I want to fight with dignity." ”

This battle was the battle of Liwei, and the best way for Zhang Xuan to establish his prestige in the entire south was to find a strong enemy and defeat him with dignity.

Since Zhang Xuan didn't want to hide his whereabouts.

The news spread quickly.

The most shocking was Li Guo.

Li Guo looked at the layers of boats on Dongting Lake, and wanted to break his finger bones for a while.

He was angry and didn't know who to vent to.

Because he knew that this battle could not be avoided.

But he didn't have much confidence in this battle, but now he can't go if he wants to.

Retreat has always been a military dilemma.

Especially retreat in the face of a strong enemy. It's a problem within a problem.

After Li Guo took a deep breath and calmed himself, he began to gather the generals to arrange tasks and vacate a small town, using the rammed earth wall of the town, which was only two feet long, as his own support.

Prepare for battle.

However, when the saber rattling was here, under the city of Changsha, Xu Du had already begun to officially attack.

"Boom, boom, boom." A cannon rang out. suppressed a cannon sound, and the layers of cannon sounds made people feel as if there was rolling thunder in their ears.

Xu Du learned to use artillery almost without a teacher, he mobilized more than 20 artillery pieces, lined up on the east bank of the Xiangjiang River, and personally led the infantry to protect the artillery. It seems to have the feeling of being camped on the east bank of the river.

Dozens of Hongyi cannons bombarded the city walls almost day and night.

The city wall chosen by Xu Du is also a new city wall, which was restored within half a year after being destroyed by Zhang Xianzhong.

Under such a dense bombardment, there were some shaky ones.

But that alone wasn't enough to terrify the city. But he also carried out another plan, which was to send troops to blockade the entire Liuyang River. cleaned up both sides of the Liuyang River, and then sent many prisoners to work day and night as people's husbands. By the way, people from all over the country were recruited to come to Liuyang River to do things.

There are so many people that a lot of news can't be hidden. Xu Du didn't even mean to hide it.

So many people know what Xia Jun is going to do outside the city.

They want to seal the Liuyang River and make the Liuyang River rush to Changsha City.

As soon as the news came out, the city shook.

For a while, there was all the news, true or false.

It is said that Zhang Xuan was ready to flood Changsha by the Xiangjiang River, but the amount of work was too large, so he gave up and chose the Liuyang River instead.

Some people say that it will rain a lot in autumn today, and even if it is not a river, there will still be a difficulty to overcome in autumn, let alone a river that will be broken now.

The news spread wildly to Longwu's ears for a while.

Longwu was also a little restless.

Since ancient times, the use of soldiers has been ruthless, and there is no better than fire and water. When he thinks of flooding Changsha, he thinks of many, many things.

Recently, the city of Kaifeng was flooded. The more ancient, such as Zhibo flooded Jinyang, Wang Ben flooded Daliang City.

Counting the riverside cities in China, there are very few that have not been flooded.

Generally speaking, to flood a city, there are several requirements, first of all, there must be a river, and the river cannot be small.

Outside Changsha, there are Liuyang River, Xiangjiang River, Liuyang River does not say, Xiangjiang River can not be regarded as a small river.

And according to the season, at least during the rainy season.

And now it's summer, and it's almost autumn. This is the time of heavy rainfall in previous years.

They scrutinized it carefully, and suddenly felt that it was tightly matched. Don't dare to slack off, and discuss how to deal with this situation.

In fact, they also think highly of Xu Du.

Flooding a city looks like a military operation, but it's actually a water conservancy project.

Except for the Yellow River, which is a hanging river on the ground, it is only necessary to dig the embankment and flood the city, and the rest of the cities must be well planned.

Because the ancients were not fools either. Ancient Chinese siege methods, who does not know, so when building a city, this issue will be considered.

Of course, it is just a consideration, and it is not possible to build all the cities on the mountains for the sake of flood control in the future.

But since you have thought about it, there are many ways to drain the water. If nothing else, just look at the sewer system in Ganzhou.

The sewer system of the Song Dynasty was more powerful than the sewer system of many modern cities.

It can drain water and prevent flood backflow.

Therefore, it is really not something that ordinary people can do to flood the city, and there is a lot of water conservancy knowledge in it.

The reason why Xu Du did this was to confuse the public, attract Longwu's attention, and let the decision-makers of the Ming army know that Xu Du was testing the city defense while preparing to flood Changsha City.

The reason why Xu Du did this was also a little selfish.

His selfishness is to conquer Changsha City alone. The matter of intercepting water and irrigating the city has always been to believe that it exists rather than believe that it does not exist.

Therefore, Xu Du envisioned that the best way for him to be in Longwu's position was to go to war and destroy the ongoing project.

Of course, it would be better to defeat the enemy and relieve the siege of Changsha.

Xu Du has also seen Changsha City and knows that it is a hard bone. If you hit hard, Xu Du won't be able to beat it at all. After all, the main force has already gone downstream.

But if you are in the field, Xu Du is not afraid of the soldiers in Changsha City. But Xu Du also knew that Longwu in Changsha City also knew, so Longwu would not order to go out of the city to fight.

Xu had to give Longwu a reason to have to go out of the city.

It is also appropriate to use a non-existent levee as a bait. If everything goes well, while Zhang Xuan solves Li Guo, Xu Du can also solve most of Changsha's troops. As for whether Changsha City can be captured, it depends on the next situation.

Xu Du is now full of hope and waiting for the Ming army to throw himself into the net. Although Long Wu didn't know Zhang Xuan's mind outside the city now. But he was also worried about whether Changsha City would sink into the Hunan water, and he couldn't sleep at night.

Yes, it's Zhang Xuan, the news of Zhang Xuan's army mobilization is hidden in a lot of messy news, and Longwu has not confirmed it yet.
