This time is like an arrow, the sun and the moon are like shuttles, and in the blink of an eye, Yang Hu has been operating in Jingzhou for nearly ten years. At this time, the last famous general of the State of Wu, Lu Kang, had already died, and Yang Hu felt that the opportunity to cut down Wu on a large scale had arrived, so he wrote a letter to Sima Yan, the emperor of the Jin Dynasty, which is the famous "Please Cut Down Wu Shu", and we briefly repeat the content of the Song Shu here.

Your Majesty, your father Sima Zhao, in accordance with the Way of Heaven, went west to pacify the Shu kingdom and went south to live in peace with the state of Wu, and over the years, the Jin kingdom rested and recuperated, and the people lived and worked in peace and contentment. But Wu Guo is not honest, from time to time he provokes incidents at the border, and it is not okay not to clean up completely.
The matter of fighting a war cannot be avoided by the famous kings and lords of all generations. In the past, Emperor Yao rebelled in Danshui, and Emperor Shun also attacked Sanmiao, and their purpose was the same, that is, to stabilize the world and to avoid war. When the Shu Kingdom fell, everyone in the world felt that the Wu Kingdom would also perish together, and now that thirteen years had passed, it was time to close the net.
For the crusade against the State of Wu, there were some objections within the State of Jin, and some people felt that the State of Wu had the Yangtze River Natural Danger, which was not so easy to overcome, but they only understood the literal meaning of the Heavenly Danger, and did not understand the deeper truth behind it. If the strength of the two sides is equal, then natural danger can help defense, if the strength of the two sides is very different, that is, there is a natural risk, and then there are resourceful talents, it is useless.
At that time, the Shu state as an independent country, the terrain was dangerous, often there was a husband and wife to close the border, but when the army pressed the border, almost all the way to the defense, the Wei army has been fighting to Chengdu, not even a decent resistance encountered. That was mainly the reason why the Shu people thought that the gap in strength between the two sides was too large and did not intend to fight.
Today's Wu Kingdom, the terrain around Jianghuai, there is no sword pavilion danger, the mountains and rivers are not as dangerous as the Min Han area, Sun Hao's brutality, better than Liu Chan, the hardships of the Wu people, far more than the Shu people of that year. Correspondingly, the number of troops in our Jin dynasty has exceeded that year, and the materials and equipment are much more sufficient than before, if we do not send troops to pacify the Wu state now and continue to support the defense of the army, it will be so that the strength will be consumed day by day, and the situation in the future is likely to change.
I have long thought of the strategy for attacking the state of Wu, we can mobilize the armies of Yizhou and Liangzhou to the east, the army around Jingzhou to attack Jiangling, the army of Pingnan and Yuzhou to attack Xiakou, and the large armies of Xuzhou, Yangzhou, Qingzhou and Yanzhou directly attack the capital of the State of Wu, Jianye. Several large armies marched together, so that the Wu people could not defend, even if they wanted to defend, but all important parts were attacked, and they could not prevent it if they wanted to.
The above is our advantage, and the next is to talk about the disadvantages of Wu Guo.
Sun Hao was too indulgent of his own selfish desires, and he was very suspicious of his subordinates, and many important ministers could not be trusted, and many people surrendered to our country one after another. Their generals were suspected in the imperial court, soldiers suffered in the wilderness, and in ordinary days there would be people who would consider whether to go or stay, and when our army pressed the border, there would be many people who took the initiative to respond, and this battle would be easier to fight.
After so many years of running-in, we have clearly seen that the Wu people are better at quick battles and quick decisions, they can't afford protracted wars, crossbows and weapons and other things, they are far inferior to China, the only advantage is in water warfare. But we marched several times, and once we hit the territory of the Wu Kingdom, the Yangtze River was not their unique advantage.
At that time, the Wu people withdrew their troops to defend the city, we went deep into the enemy's territory, we were determined to complete the determination to unify the world, the Wu people only had a nervous defensive heart, with the advantages of our army, it is quite natural to want to win such a battle.
After reading yanghu's recital, Sima Yan was very much in favor of it, but after all, the Jin state was not his own country, or he still had to consult with the ministers, and at that time, within the Jin court, the voice opposing the attack on the state of Wu was still very loud, you such as our old acquaintance Jia Chong, he was very opposed, and Xun Xun, Feng Zhen and other important ministers also expressed opposition. They also put forward a full reason, at that time in the northwest of Qinzhou, Liangzhou, the Xianbei people were not very convinced of the Jin state, the two sides were going to war, they pointed out that to do things must be concentrated to do a good job, can not fight on both fronts at the same time. However, there were also a small number of people who agreed with Yang Hu's views, including Du Pre and Zhongshu Ling Zhang Hua, but their opinions could not occupy a dominant position, so Sima Yan had to postpone his plan to attack the State of Wu.
As for the matter of the Jin state fighting with the Xianbei people, Yang Hu also knew, once the Jin state was defeated by the Xianbei people in Qinzhou and Liangzhou, Yang Hu took the opportunity to say that it is still necessary to distinguish the primary and secondary relations in doing things, if the Wu state is pacified, then the Jin state can unify the world, and the little Hu people naturally do not dare to create a second, so the most urgent thing at the moment is to complete the great plan to destroy Wu!
Unfortunately, most of the courtiers of the Jin Dynasty did not recognize Yang Hu's opinion, and Yang Hu sighed, "Things in the world, nine times out of ten, can not be satisfactory, when the break continues, God gave the opportunity but did not want it, it is really regrettable!
