In 228 AD, Zhuge Liang "raised his voice and got eyebrows from Gu Jie Road, which made Zhao Yun and Deng Zhi suspect that he was leading troops. According to Ji Gu, Wei General Cao Zhen rejected them. " Because "Wei people know that Shu is prepared, but they don't know." (It can also be seen how unknown Zhuge Liang was at that time), which led to "Nan 'an, Tianshui and Yong 'an counties rebelled against Wei Liangying, and Guanzhong shook." Generally speaking, Zhuge Liang made careful preparations before the Northern Expedition, and Wei thought that Liu Bei could rest easy after his death. He was not prepared for the war and was at a disadvantage, so "Chang 'an, the west town of Wei Mingdi, ordered Zhang Tai to refuse to take photos" and "the emperor sent a team, with Cao Zhen as the commander in chief and Zhang Tai as the pioneer. Of course, it is even more impossible to get away with it. It should be said that this time the situation is very favorable to Zhuge Liang, especially in Tianshui and Liangzhou counties, where there are a lot of military supplies. Once occupied, the food shortage of the Shu army could be greatly alleviated, but Zhuge Liang was slow to enter the three counties in time, which led him to fight Wei Jun in Jieting. In the selection of combat generals, "there are old generals Wei Yan and Wu Yi. And all commentators said that it is appropriate to make it. " Although Zhuge Liang kept saying that he trusted Liu Bei, he forgot what Liu Bei said at this critical moment. Unfortunately, in this operation, "we have to rely on the resistance of Nanshan, and we can't go down to the city." Cut off its drainage, hit it and break it. At the same time, Zhao Yun and Deng Zhi were destroyed by Yeh in Ji Gu. Only Wang Ping returned safely without losing a single soldier. "Sima Wang Xuan, after hearing Zhuge Liang's defeat, was in charge of Jingzhou's water conservancy army and wanted to cut Wu into the river, so he ordered the rectification of the Guanzhong armies. "In Jingzhou, the water is shallow in winter, and the big ship can't sail, but we have to go back to Fangcheng." Sima yi lost an opportunity to make contributions because of the low water.
In this Northern Expedition, Zhuge Liang fought more and less (Liang said: "There were many thieves in Qishan and our army, but the thieves were not broken." In order to prepare for the attack, he was defeated and he was embarrassed. He had to "go up and ask himself to drop third class". It seems to be punished, but in fact it is "for the right general, doing the thing of the prime minister, such as being the president before." -it is still the military and political power. On the other hand, in Cao Wei, Zhang Tai made meritorious deeds and sealed Wan Huhou.
After the first Northern Expedition, Cao Wei was surprised to find that there was a catastrophe on his own border. Besides Soochow, there was also Xishu, so he entrusted Cao Zhen with the important task of guarding Xishu. Cao Zhen "killed Qishan with Zhuge Liang, and then left Chencang, and let General Zhao Hao and others guard Chencang and rule its city." He predicted Zhuge Liang's attack direction nine months in advance and made preparations. In the winter of 228, Cao Xiu, the general of Wei Dongfang, received a letter from the Zhoufu in Wujiang, saying, "Don't listen to his words, ride a hundred thousand troops to Anhui to respond;" The emperor also sent Sima Yi to Jiangling and Jia Kui to the east, and all three made progress. " Unexpectedly, Zhou Fu pretended to surrender, and Cao Xiu was destroyed by Lu Xun in Shi Ting. Sima yi had to return in vain. After Zhuge Liang learned the news, he began to stir again. "In December, Liang Lingbing through, surrounded their positions. Chen Cang is ready, and Liang cannot be defeated. "Zhuge Liang knew that Chen Cang had defenders and still chose to go through customs from now on, which shows the difference of his military level. "Bright has tens of thousands of people, and only a few thousand people, zhao soldiers and degrees east rescue failed to arrive, but the invasion of zhao, ladder rushed to the city. Zhao shot back to the ladder with a rocket, and everyone on the ladder was burned to death. Zhao also crushed the car with a rope and a stone mill, and the car broke. Liang shot at the city with a hundred feet of well, filled the incision with earth pills, and wanted to take the city directly, so Zhao built a heavy wall inside. Liang and Tu Li want to jump out of the city, and Zhao crosses the ground in the city again. Attack day and night for more than 20 days. " Zhuge Liang, with his own strength dozens of times that of the enemy, could not capture a small position. At this time, "the emperor called Zhang He to Fangcheng to strike Ming." "The emperor rejoiced in Henan, so he bought wine and sent it to him. He asked,' The general arrived too late and too bright. Isn't it fun?' Knowing that Liang had entered the valley, he pointed his finger and said, "He has arrived and Liang has gone." As expected, Zhuge Liang had already withdrawn before Zhang He arrived.
Then in the spring of 229 and 230, Zhuge Liang sent Chen Shi and Wei Yan to attack twice, but they were not as clever as Zhuge Liang and the soldiers at the front were stronger than Ma Zhuang, and both of them played their own level. After capturing the two counties of level tone and Wudu, Wei Yan spent a lot of money on Yao and Guo Huai. It achieved the effect that Zhuge Liang himself could not achieve.
February 23 1 year, "Liang Shuai army invaded, surrounded Qishan, and used wooden oxen to run horses. At that time, Sima Cao was really ill, and the emperor ordered Sima Yi to go to Chang 'an in the west. The generals of the army were Zhang He, Fei Yao, Dai Ling and Guo Huai. "Sima Yi, who has been suppressed by Cao Zhen, finally has a chance to compete with Zhuge Liang.
Let's see how Sima Yi acted: "Sima Yi asked Fei Yao and Dai Ling to leave 4,000 chosen men on the raft, and the rest of them learned that they were going to save Qishan in the west. Zhang He wanted to divide his troops between Yong and Jia, and Yi said,' It is expected that the former army can be independent and the general is right. If you can't tell the difference, all the three armies of Chu are birds. "Then move on." This is the first time that Sima Yi has commanded such an army to fight. Sima yi won his trust only because he gave many ideas for xelloss, and later became the minister of life, and he didn't have much combat experience. ) He is eager to make achievements and his command ability is not high, so he is enterprising. The result was defeated by Wei Yan and Wu Ban, killing and injuring 3,000 people. But he can learn a lesson immediately-since he can't defeat the enemy on the battlefield like Cao Zhen, he will take a step-by-step approach and keep Zhuge Liang out. Sure enough, Zhuge Liang could do nothing. In June, he ran out of food and had to retreat again. At this time, Sima Yi was far from reaching the control level in the later period. At that time, he got carried away and ordered Zhang He to pursue him. Zhang He, who has been through many battles, advised him: "Sun Tzu's art of war has a cloud, so don't pursue troops." Sima Yi forced Zhang He to go. In desperation, Zhang He had to be ordered to pursue, only to be ambushed, and a generation of famous soldiers also made random arrows. In fact, if Zhuge Liang is a nemesis, it must belong to Zhang He. If Ye Zhen is still here, why did Zhang He die, and why did Wei Jun rely on more food to win? Unfortunately, Cao Zhen died in Chang 'an in early March. However, under the leadership of Sima Yi, who was not good at leading troops, Wei Jun's winning method became increasingly negative.
The last moment has finally arrived. In February 234, Zhuge Liang mobilized "hundreds of thousands of people to invade, and at the same time sent envoys to Wu." "Zhuge Liang is the best, and the army is in the south of Weishui. Sima Yi led the army to cross the Weihe River and refused it with the back water as the base. " At this time, Sima Yi already had the experience of playing against Zhuge Liang. His opponent said: "If you are smart and brave, you will be worried if you lean on the mountain to the east;" If you go to the west five yards, there will be nothing. " Zhuge Liang, who was weaker than the military, really marched into Wuzhangyuan. This time, Sima Yi no longer rashly attacked, but continued to guard. Every time Zhuge Liang challenged, Sima Yi ignored it. Zhuge Liang wants to fight, but also wants to retreat, but he is not reconciled. So he also divided his troops and set the scene in an attempt to continue to fight against Sima Yi. Unfortunately, he died in August, and the attack on Wei vanished. In this battle, both sides tried to foster strengths and avoid weaknesses: Zhuge Liang wanted to fight in the field and Sima Yi wanted to fight in the city. In the end, Sima Yi resisted the pressure, gained a firm foothold and won.
In fact, compared with Cao Cao, Zhou Yu, Lu Xun, Sima Yi and Zhuge Liang, we can only compare with them politically. Militarily, they are even weaker than Wei Yan, Zhang He and Cao Zhen. Therefore, when paying attention to the famous Northern Expedition, please don't always make a fuss about these two people. After all, compared with the heroes who broke out in the early days of the Three Kingdoms, they were only heroes in the declining period.
