On the evening of 16 October, Cao Jun had already arrived outside the city of Hefei.

Guan Yu stood on the head of the city and frowned.

Behind him, a middle-aged scholar with his hands in his sleeves and a slight bend in a humble gesture.

The evening breeze gently blew on their faces, blowing their robes in the wind.

Guan Yu said in a deep voice: "Hefei City was brought down by me with great difficulty, so let me give up, Lu Boyan, are you joking?" ”

Lu Xun said with a smile: "The prince should understand a truth, this is always the case in this world, there is giving, there is gain." If the first emperor could not abandon the north, how could he dominate the world in the south? Abandon first, then take, the right way. ”

Guan Yu felt that Lu Xun was talking crookedly, so he shook his head and said: "I never feel that I should give up first and then take it in my life, if it is for victory, it is not a bad thing to avoid it for a short time." But what I want to ask you is, what if Cao Jun only captured Hefei after going south, and then did not continue to pursue? ”

Since the Yellow Turban Rebellion, Guan Yu has followed Liu Bei to fight in the south and north for many years. He didn't understand the principle of strategic abandonment. What he is afraid of is that the enemy will not be tricked at all, if he withdraws his troops back, people will only occupy Hefei, then he has been fighting for a year in Hefei, won't it be in vain?

Lu Xun said softly: "Don't worry, the prince will give the enemy a reason that he can't refuse." What's more, if the prince is worried, it is simple. When you leave, set a fire and burn this Hefei city, anyway, doesn't the prince also plan to cast a new city? ”

"Burned Hefei?"

A hint of surprise flashed on Guan Yu's old face, and after a while, he turned around and said slowly: "Then do what you want, if it doesn't work, I will behead you." ”

"Yes."

Lu Xun still had his hands in his sleeves and raised his head to look at the sky.

It's early winter in October.

There was no snow in Huainan, and after the rainy season, the weather was a little dry like in late autumn.

The breeze blows the willows on the bank of the Shishui River, and the surface of Chaohu Lake in the distance reflects the sunset like a mirror.

The mountains at sunset are withered yellow autumn leaves, the maple leaves are red in February, and there are waterfowl soaring in the sky.

It's a good day to set fires.

Lu Xun thought to himself.

Outside the city of Hefei, in the camp of the Cao army.

Cao Xiu sat on the main seat, and more than ten people from Lu Qian, Zang Ba, Xue Yi and other subordinates sat down.

In addition to them, Liu Ye and Jiang Ji were also sent as staff officers.

In this raid on Huainan, Cao Wei transferred the Youzhou cavalry from the north to Henan, and once the reinforcements from Nanyang rushed to help, the cavalry would raid the Nanyang Basin.

Therefore, even if this plan did not succeed in taking Huainan back, it didn't matter if Sun Quan didn't do anything big in the rear.

The worst result is that they withdraw, and then the main force of Henan, Cao's army, turns Nanyang upside down.

But the good news came.

Sun Quan's side had already burned Jianye's granary, and according to their intelligence estimates, Guan Yu only had less than two months of military rations left at most.

"This is a letter sent by Sun Quan's ministry to Gu Li, and our scouts have also detected that Jianye Taicang is indeed on fire."

Cao Xiu threw the official document in his hand on the table, looked around and said: "According to the investigation before, Guan Yu had a year of grain and grass in Hefei Tun, but this year's spring rice harvest has been delayed, and the autumn rice has just been harvested, and the grain should arrive at the end of October." ”

"But last year's grain delivery was in December, does that mean that Guan Yu only has two months of grain and grass now?"

Lu Qian asked.

"Not bad."

Cao Xiu nodded: "Since Guan Yu's attack on Hefei, we have been closely observing their grain ships in Yangzhou, and we are clear about every large-scale grain shipment they have, in December last year, Guan Yu had just captured Hefei at that time, and our Xizuo saw the grain fleet sail into Hefei City. ”

When Guan Yu first attacked Hefei, the grain and grass were not concentrated in his own camp, but placed separately, and the grain was stored in Chao County in the south, and only two months of grain and grass were left in the camp.

It's not that they don't want to put food in the camp as well, but for the sake of safety.

It's like Yuan Shao will put the grain in the black nest is a reason, when besieging the enemy, if it is placed in the headquarters camp, once the treasury is attacked, the risk will be relatively large.

Therefore, in history, whether it was Yuan Shao or Cao Cao, they often did not choose to store grain in the barracks, but found another place.

Yuan Shao is choosing to be in the black nest.

Cao Cao, on the other hand, chose to put the grain on the water.

For example, every time Cao Cao attacked the enemy, the way to transport grain was mostly by water, and he besieged Yecheng and dug a white ditch. When Yuan Tan, Yuan Shang, Yuan Xi and others were pacified, they dug the Pingyu Canal and the Quanzhou Canal, and then went south to fight the Battle of Chibi, dredge the water and so on to transport grain and grass.

In this way, when he attacked the enemy, he did not need to store too much grain and grass in the camp, and every time he transported grain by ship, he did not have to worry about being robbed of the grain route, and secondly, he did not have to worry about the camp being breached and the grain being burned.

Guan Yu's siege of Hefei was the same, the grain was stored in the rear of the area from Weixukou to Chaoxian, and the grain was transported by ship through Chaohu Lake and water to the camp outside Hefei.

Cao Jun did not have a fleet, so naturally he could not threaten his food security.

But then laid down the city of Hefei, after having the city, it is necessary to abandon such a way, the cost of transporting grain is too great, and it is obviously much easier to transport grain to the city for storage at one time than to continuously transport grain back and forth.

Therefore, now Guan Yu has changed the way of transporting grain.

The main thing is that the way the city plays is like this, and when besieging others, you can rely on water transportation.

However, if the city is besieged by the enemy when defending the city, the water canal may be cut off, so when there is a city to store food, it is natural to focus on the defense of the city.

The current situation is that Guan Yu's 80,000 horses and horses captured Huainan, and the soldiers and horses were not all concentrated in Hefei City, but along the mouth of the river all the way to Hefei City, and Jiujiang, Lujiang and other counties in Huainan still had Han troops scattered and garrisoned, resulting in his soldiers and horses could not all be gathered together.

The Cao army gathered all the soldiers and horses of Runan, Guangling, Peiguo, etc., and a total of 120,000 troops marched south to surround the city of Hefei. When the number of enemies is relatively large, it is obviously not suitable to go out of the city and set up camp, and then transport grain by water.

It's just that the problem is that the new grain has not been delivered and has been burned, so this will be a huge blow to Guan Yujun, who still has two months of grain and grass left.

Zang Ba said: "If that's the case, then wouldn't Guan Yu be about to withdraw his troops?" ”

"Nope."

Jiang Ji shook his head and said: "Guan Yu will definitely be furious when he first hears that the grain and grass in the south are on fire, but Hefei City, which was finally defeated, will never be lost so easily, so I think that he will definitely hold on for a period of time and urge the rear to transport grain." ”

"Hmm."

Cao Xiu felt that it made sense, so he said: "But Guan Yu has a naval army stationed on Chaohu Lake, if we want to rob the grain road, our naval army may not be able to defeat them." ”

In addition to the 30,000 defenders in Hefei City, the Han army also built a water dock fort and a dock in Chaohu Lake in the south, with an army of about 20,000.

The Wei army had already sent men and horses to attack and harass, but it could not prevent their naval army from entering Shishui or retreating into Chaohu Lake, especially Hefei City was on the edge of Shishui, and the fleet could enter Shishui to meet Guan Yu's troops.

Although for this raid, Cao Wei also prepared some ships, and from Shaobi Lake, he could go south along Shishui, the problem was that Cao Wei's navy was basically at a level that could help the army cross the river, and it was whimsical to want to fight with the Jiangdong sailors on Chaohu Lake.

This was also proved by Zhuge Ke's battle of Dongxing later. Cao Wei fought to Dongxingti, but Zhuge Ke only sent Ding Feng thousands of people to raid by boat, and defeated the Cao army that built a camp on the water, and the Cao army drowned countless people in order to fight for the pontoon bridge.

Therefore, the northerners are not good at water warfare, which is indeed a relatively recognized thing.

Liu Ye said: "If you want to defeat Guan Yu, you must attack the mouth of the water in advance and block the retreat of his troops. ”

"It's that easy."

Cao Xiu shook his head and said, "Guan Yu will not withdraw his troops immediately, and our naval army will not be able to pass and cannot be intercepted." ”

Jiang Ji said with a smile: "There are other ways, if Jiangdong is at risk of being breached, then Guan Yu is in a hurry to return for reinforcements, and he will definitely evacuate, as long as we cross the river, we may even capture the entire Jiangdong." ”

"Will Guan Yu let us cross the river?"

Cao Xiu laughed at himself: "People won't be stupid enough not to place a naval army to intercept it on the river." ”

Jiang Ji said: "So Guan Yu has to be withdrawn, the lack of grain and grass is only the first step, and the second step is to be cut off from the back road." ”

"You mean Sun Quan?"

Cao Xiu sneered: "This guy has not moved, saying that he has fled back to Jiangdong from Xiangyang, but the south has not raised anything so far, and he said that he would send troops together, but unfortunately this fang is afraid that he is as timid as a mouse." ”

"Report!"

At this time, the messenger outside the door hurriedly came in and shouted: "Sun Quan has sent a letter, saying that he has already raised an incident in Huiji Linhai, attacked the county seat, and occupied the land of the second county. ”

"Oh?"

Cao Xiu was surprised: "I didn't expect him to really do it." ”

Liu Ye immediately said: "General, let's march." If Guan Yu hesitates and does not choose to withdraw his troops, then we can just besiege him, as long as we break the mouth of the water and build iron locks on the water to intercept their fleet, Guan Yu will have nowhere to escape! ”

"Marching Tomorrow!"

Cao Xiu waved his hand, it was getting late today, and he could only act tomorrow.

However, at night, fires broke out in the city of Hefei.

By dawn, the entire city had been burned down, and Guan Yu's main force had fled to the ship and left south.

Seeing this situation, Cao Xiu knew that it was Sun Quan in the rear who put pressure on Guan Yu, so he immediately stopped hesitating and ordered the three armies to pursue, even if Guan Yu had crossed the river, their main force must cross the Yangtze River.

October 21, Wu County, Qiantang County.

At the time of the morning meal, Sun Quanjun in the distance had already crossed the Qiantang River and arrived outside the city of Qiantang.

At this moment, Sun Quan was riding on horseback, and in addition to the general Gu Li, there were several brave and warlike young generals around him, all of whom were children of the family.

Liu Bei was not very friendly to the Jiangdong scholars, so this time Sun Quan was restored, a large number of Jiangdong scholars contributed people, although they barely managed to gather 20,000 people, but after they launched an uprising, in just ten days, they broke through several county seats, occupying Linhai County and Huiji County.

There are not many defenders in the two counties, and they are not their opponents at all, Wu County Taishou Liu Shen is a big clan in Shu County, and he previously served as Liu Bei's Yizhou Don't Drive, and now he is transferred to Wu County, and when he heard that Sun Quan had returned, he hastily mobilized thousands of county soldiers to Qian Tang for defense.

On the city of Qiantang, Liu Shen saw Sun Quanjun crossing the river from a distance, so he said to the soldiers around him: "Sun Tzu: The Marching Chapter says: "The guest comes from the water, do not welcome him in the water, so that he can hit it half-helped, and it will be profitable." Now that the enemy is crossing the river, we should also go out of the city and strike while they are still crossed. ”

So he led thousands of men out of the city.

Sun Quan saw that the gate of Qiantang City was opened, and the enemy came to prepare to attack halfway, so he also said to the left and right: "This battle is whether Lone can gain a foothold in Jiangdong again, you must think clearly, after Lone returns, the land and population of your clan will go back, for the sake of the clan, you must go all out." ”

"Yui!"

Gu Li and several young players should be.

At that moment, Sun Quan said again: "Now that the army is crossing the river, we can't let them attack halfway, you go with me to engage it and cover the rear soldiers and horses." As long as he occupies Wu County and cooperates with Cao's army to annihilate Guan Yu, Gu will be able to revive Jiangdong. ”

Saying that, he rode his horse and went into battle in person.

Sun Quan is actually very bold, and he likes to be alone in front every time he fights, but he doesn't have the force value of his father and brother, so he has made a lot of jokes.

However, this is the key to his recovery, so even if he knows that his force is insufficient, he must go into battle in person.

Soon, thousands of soldiers rushed towards the Han army in the distance.

The two sides quickly approached.

There was a relative lack of bows and crossbows on both sides, so as soon as they got closer, they began to line up their formations, intending to start hand-to-hand combat directly.

Liu Shen rode out of the horse, saw Sun Quan from a distance, and scolded: "Sun Quan, you repeatedly betrayed the covenant and attacked the first emperor back then, even if you were captured later, the first emperor was benevolent and never treated you badly. Why did you escape from Xiangyang and rebel again? ”

"Hahahahaha."

Sun Quan laughed and said: "Jiangdong is the foundation laid down by my father and brother, why should I give it to others?" Liu Xuande is a puppet, a weaver and a shoe seller, and he is also worthy of being a lonely master? Dream! ”

Liu Shen sneered: "In vain, your father and brother are heroes, but I didn't expect to have such an unbelieving and unrighteous son of the Sun family as you." Sun Quan, listen, if you want to take Jiangdong, it's easy to take my Wu County. If you dare to shout three times on the horse, I am a Jiangdong Xinyi hero, who dares to kill me! I admire you and give up the soldiers and horses to you. ”

"Oh?"

Sun Quan laughed and said, "Liu Shenpifu, are you trying to humiliate me?" ”

Liu Shen sneered: "I don't think you have that face." ”

"Hahaha."

Sun Quan looked up to the sky and laughed: "I am a Jiangdong Xinyi hero, who dares to kill me!" ”

"I am Jiangdong Xinyi hero, who dares to kill me!"

"I am Jiangdong Xinyi hero, who dares to kill me!"

The voice was loud and loud, so that the people around him who knew that Sun Quan had always liked treachery silently lowered their heads.

A young general seemed to be completely unable to stand his cheek, which was thicker than the city wall, raised the knife in his hand and said angrily: "You faithless and unrighteous rat, I dare to kill you!" ”

Before the words fell, the knife fell.

Swish!

Heads flying.

The old rule, go on a date in the field, one change today and tomorrow, and come back the day after tomorrow to continue the two changes.
