After Cao Pi ascended to the throne, because of Sun Quan's betrayal, he focused on the southeast, and Sun Quan could be said to be pressed and couldn't raise his head, and he was basically beaten. Pen, fun, pavilion www. biquge。 However, although Cao Pi suppressed Eastern Wu, it was like that, because of the gap between the water army, Cao Pi actually had no good way to deal with Sun Quan.

[Suppressing Sun Wu]

Cao Pi was not reconciled after the defeat of the three-way southern expedition against Sun Wu in the third year of the early Huang dynasty (222), and after that, he also prepared to crusade against Sun Quan many times, but most of them did not form an offensive.

In the fifth year of the early Huang dynasty (224), Cao Pi once again wanted to mobilize a large army to attack Eastern Wu, and Xin Bi advised: "The people of Wu and Chu are difficult to control. Winning with morality, they naturally surrender; If morality decays, they will defect. This situation did not begin today, and the ancients regarded them as a serious problem. Now that Your Majesty owns the world, can those who disrespect you last long? In the past, Nanyue Wei Tuo was called the emperor, and Gongsun Shu was called the Son of Heaven, but the result was not long, and he either surrendered or was killed. Why? Contrary to the avenue, so it will not be preserved for a long time. If there is great virtue, there is no one who is not convinced. Today, however, the land is empty and the population is sparse. Under normal circumstances, if you want to send an army to fight, the imperial court must be strategic. In this way, when it comes to sending troops, I still have to worry about it, I am afraid that it will not be well thought out, and now that this minimum work has not been handled, I think it is really impossible to win. The first emperor mobilized his army more than once, but each time he only hit the riverside and returned. Today, the number of troops is not as large as in the past, but it is not easy to win because it still has to send divisions. The best policy should be to follow Fan Li's method to recuperate and recuperate, so that the people can live and work in peace and contentment; In accordance with the law of the management of the Zhong, govern the affairs of the state; Then, following Zhao Chongguo's method of tuntian, he affirmed Confucius's policy of pacifying distant places. If this is the case, ten years from now, the strong people of today will still be young and strong, and the children will have grown up, and everyone will be able to participate in the war, and millions of inhabitants will know justice, and the officers and men will fight for the country with all their might. At this time, the use of soldiers is invincible. ”

Cao Pi said: "In your opinion, do you still want to leave the enemy to our children and grandchildren to destroy?" Xin Bi replied, "In the past, King Wen of Zhou left Shang to King Wu of Zhou to destroy, and he was well aware of the situation. If the times are unfavorable, it can be tolerated for a while. Cao Pi didn't listen, and Sima Yi guarded Xuchang, or led the crowd to attack Wu, Cao Pi personally commanded the navy by dragon boat, and entered the Huai River along the Cai River and Yingshui, and arrived at Shouchun. In September of the same year, he arrived in Guangling.

At that time, Emperor Cao Pi of Wei personally went to Sikou in Guangling County and ordered all the military horses of Jingzhou and Yangzhou to march together. So he summoned the ministers and asked, "Will Sun Quan himself come?" Everyone said: "Your Majesty personally went out on the expedition, Sun Quan was terrifying, and he would definitely respond to the battle with the strength of the whole country." He did not dare to entrust the command of the army to the minister, and he would definitely lead it himself. ”

Liu Ye said: "He thinks that His Majesty will tie himself up with the precious status of the emperor, and it is other generals who lead the troops to cross the river to fight, so he will definitely organize the army, wait for things to change, and will not attack in person." Emperor Wen's car stopped for many days, but Sun Quan really didn't come, so Emperor Wen returned with the army and said, "Your estimate is correct." We should consider a strategy to eliminate the two thieves Sun and Liu for me, and we can't just understand their situation. ”

After Cao Pi went out to Guangling, he asked Wei Zhen to be the leader of the army and accompany him. Cao Xiu, the general of the Eastern Expedition, sent a seal to Cao Pi, saying that he had received a confession from the general of the Wu army, saying that "Sun Quan has come to the mouth of the water." Wei Zhen said: "Although Sun Quan has the Yangtze River to rely on, he does not dare to compete with our army, this must be a rumor spread by the enemy army out of fear." After interrogating the general in detail, I learned that it was indeed a lie made by the general of the Wu army.

Wu Andong's general, Xu Shengxian, planned to build a fence around Jianye, make a fence, set up a fake building on the fence, and prepare a floating boat in the river. The generals didn't think it made much sense to do this, but Xu Sheng insisted on his opinion and completed a series of settings. When Cao Pi's army arrived at Guangling, he saw the fence that stretched for hundreds of miles, and he was suspicious, and saw that the Yangtze River was rising, so he led the army to retreat. Only then did the generals understand that Xu Sheng was prescient, and they all bowed down.

According to the record of "Wei's Spring and Autumn Period": Emperor Wen looked at the river and sighed: "Although Wei has thousands of iron horses, it is useless, and it seems that it is impossible to win!" ”

According to the record of "Wu Lu", it is the winter Wei Emperor Wen to Guangling, the river to watch the soldiers, there are more than 100,000 soldiers, hundreds of miles of banners, there is the ambition to cross the river. The right is strictly set and firmly held. When it was cold, the boat was not allowed to enter the river. Seeing the turbulent waves, the emperor sighed: "Wow! Gutian is so separated from the north and south! "Returned. Sun Shao sent Gao Shou and other 500 people who dared to die on the road at night, and the emperor was shocked, and Shou and others were covered by the deputy car feather.

In the following year, in the sixth year of the early Huang dynasty (225), Emperor Wen of Wei, Cao Pi, once again prepared to crusade against Sun Quan, and he convened his ministers to discuss. Bao Xin's son, Zheng Bao Xun, advised: "The imperial court has repeatedly dispatched large armies to conquer, but the reason why it has not achieved results is because Wu and Shu are dependent on each other, and with the dangerous terrain and the barrier of the Yangtze River, there are superior conditions that are difficult to overcome. Last year, the dragon boat was blocked by the waves drifting on the south bank of the Yangtze River, His Majesty was in danger, and the ministers were terrified, when the imperial court was almost capsized, and it should be used as a warning for future generations. Now that they are working hard and marching from afar, and their daily expenses need to be spent on a thousand gold, the country's money is wasted, and the cunning enemy is still there to show off his might, and I don't think it can be done anymore. When Emperor Wen heard Bao Xun's comments, he was furious and demoted Bao Xun to the post of law enforcement.

In August of this year, Emperor Wen led the naval army to set off from Qiaodi, along the whirlpool into the Huai River, and then to Xuzhou by land. In October, Cao Pi drove to the ancient city of Guangling, Linjiang to review the army, more than 100,000 soldiers, hundreds of miles of banners.

At that time, Jiang Ji stated that the waterway was difficult to pass, and presented the "Treatise on Three States" to advise Emperor Wen. Emperor Wen did not listen, so thousands of warships were stagnant in the water and could not move forward. Jiang Ji thought that it was close to the lake in the east and the Huai River in the north, and that if the water was in full bloom, the thieves would easily come to harass and invade. Thou shalt not encamp there. Emperor Wen listened to his advice and set off immediately. When it was returned to Jinghu, the lake gradually receded, and Emperor Wen left the boat to Jiang Ji. Those boats were originally scattered in hundreds of miles of water, but Jiang Ji chiseled four or five passages, gathered the boats, made mounds in advance to block the lake, and led the water to the back of the boats.

Emperor Wei Wen returned to Luoyang and said to Jiang Ji: "You can't help but figure things out. I had decided to wreck half of my ship in Lake Sanyang, but thankfully you managed to free the boat, and although it was behind me, it arrived in Qian County almost at the same time as me. And every suggestion you make, it's very much to my liking. In the future, the plan to solicit Sun Quan should be seriously studied and discussed. ”

【Unfinished Southern Expedition】

After Cao Pi came to power, although he went south many times to crusade against Sun Quan, in fact, only the first time formed an obvious offensive, and the next two times were in name only, and the two sides basically did not clash.

Of course, there are many reasons for this, one of which is obvious that Cao Pi has no way to take Sun Wu's navy, and every time he leads the army to the riverside, he can only look at the river and sigh, because of the Yangtze River's natural danger, he has no choice but to take Sun Quan.

In addition, this is also related to Cao Pi's over-anxiety, at that time Sun Quan's foundation was in Wu County, Cao Pi went directly to Guangling, and had the intention of preparing for a successful battle (Guangling County is Wu County to the south of the river), but he couldn't cross the Yangtze River alive or dead, in fact, Cao Pi didn't go to Guangling at that time and directly hit Jiangling, maybe he could still have some results, after all, Jiangling was in Jiangbei, at least he could fight, and Wu was not deeply rooted in Jingzhou.
