I'm definitely not alarmist when I say this, but it is clearly recorded in historical materials and the result of analysis by talents from the three major countries.
In other words, Shu must go north, otherwise it is only a matter of time before losing without a fight. Not only Shu, but also. At the same time of Shu's Northern Expedition, Soochow also made many northern expeditions.
After all, it is unrealistic for these two countries to change their interests.
Don't worry about Wu Dong here, just discuss why Zhuge Liang of Shu Han insisted on the road of Northern Expedition.
Look at Zhuge Liang's example first:
Before the first emperor started his business, the middle road collapsed. Today he scored three points, and Yizhou was exhausted. This is also the autumn of crisis. -Reference, "The Three Kingdoms and Zhuge Liang Chuan"
Zhuge Liang explained in the first sentence of his model that he wanted to explore the north because "the profit is exhausted, and this sincere danger is also in autumn." ; Yizhou is weak, which means that Shu is now weak in national strength. In this case, since the national strength is poor, why did Zhuge Liang want to explore the North? Because it has reached the critical moment of life and death, we can't do it without the Northern Expedition. So we have to go north.
Why does Zhuge Liang think that Shu has reached a critical moment of life and death?
The answer to this question can be found in Cao Wei.
I don't know if you have found such a problem; Wei Shuwu is divided into three parts of the world, Cao Wei is the second part, and Cao Wei is the largest country in the world. In addition, the military commanders of Cao Wei's advisers are many times more luxurious than those of Shu Han. Why is it difficult for Cao Rui to see Cao Wei take the initiative to attack Soochow and Shu Han after he ascended the throne?
The main reason why Zhuge Liang insisted on the Northern Expedition was that Cao Wei chose to recuperate rather than use troops abroad.
Because Cao Wei played a very clever card, that is, Sun Wu said that the highest state of military strategists was "to defeat the enemy without fighting", and to bring down Shu Han and Wu Dong with national strength and let them surrender without fighting.
-Next, analyze how Cao Wei achieved the goal of "conquering the enemy without fighting". Who is the initiator of this strategy?
This man is Sun Tzu, an important official of Cao Wei, and a general in ancient times. Xun You once spoke highly of Sun Tzu's talent.
Actually, Cao Rui wanted to fight. When Zhuge Liang was heavily stationed in Nanzheng, Cao Rui was about to send troops to Shu Han, and most of the etiquette in the DPRK basically agreed to attack Shu Han. Sun Tzu was the only one who strongly opposed it and finally persuaded everyone.
-First, cutting Shu lost its geographical position.
Yesterday, Emperor Wu levied Nanzheng and took the battle between Zhang Lu and Yangping to help the people in danger. Pulling out Xia Houyuan's army, he said that "Nanzheng is the Heavenly Palace, and the middle oblique valley road is 500 Li in the ear of the cave" is a deep danger, and he likes to use the words of the deep army.
Nanzheng is like a prison in the sky, and the inclined valley road in the middle is like a five hundred-mile cave. This is what Cao Cao said several times. The terrain of Shu is sinister, and the Shu Road is southbound. If Wei Jun rashly attacks Shu, it will inevitably lose its geographical position, which is unfavorable to the war.
-Second, we lost the opportunity to cut Shu.
In addition, Liang Wudi is keen on fighting, while thieves in Han Shu live among rocks. They regarded Lu Wu as a fugitive in the Jianghu and avoided him. They didn't blame the strength of the soldiers, nor did they argue about the anger of the dynasty. They sincerely said that they would fight when they saw victory and retreat when they knew difficulties.
Cao Cao fought like a god, knowing that Shu thieves lived in the mountains and Wu bandits were rampant in the rivers and lakes, so he often forbeared and avoided them for the time being. Cao Cao knew that he would not fight for a moment's revenge, nor would he force his men to fight recklessly. What does this mean? It means the time is not mature enough. If you are eager to cut Shu, you will lose the opportunity.
-third, the strength is insufficient, the front is too long and uncoordinated.
If we March into Nanzheng today, the road will be bright and dangerous. We will use elite soldiers and transport and guard the four southern States to curb water thieves. Whoever uses 150,000 or 60,000 people will be more prosperous, and the world will be turbulent and thankless. This is something your majesty should consider.
Because of the long front, material transshipment, and Cao Wei guarding Jingzhou, Xuzhou, Yangzhou and Yuzhou and defending the border of Wu Dong, we always need 150,000 troops. In order to conquer Shu, it is necessary to enlist more military service and dispatch more materials. In this case, it will only accumulate public grievances and lead to world turmoil.
So! When Cao Wei attacked Shu, he was in the right place at the right time and suffered heavy losses. ...
Au Suivant! Sun Tzu's suggestion is:
Keep your fighting power, and your fighting power will be doubled.
It takes only half the troops to turn to defense.
But today, seeing that the soldiers are divided into two ways, the general will be able to deter the powerful enemy, pacify the battlefield, the soldiers will sleep peacefully and the people will be well. In recent years, China has prospered, and Wu and Shu will perish.
-The last paragraph just explains Zhuge Liang's "this is a sincere danger, and it is the autumn of survival."
Sun Tzu told Cao Wei not to over-enlist for military service, but to use the current strength to hold dangerous places, which was enough to deter powerful enemies and make the country's borders safe and sound. In this way, soldiers can recharge their batteries, and the people can live and work in peace and contentment without suffering from hard labor. A few years later, the national strength of Wei became stronger and stronger, and the national strength of Wu and Shu became weaker and weaker, and they were defeated without fighting.
So! Zhuge Liang's eagerness for the Northern Expedition is not unreasonable. He saw through Cao Wei's strategy of recuperation, so he longed for the Northern Expedition several times. If Zhuge Liang chooses to dig deep into Bashu and save his strength, it is a sign of doing nothing.
I have to say! Sun Tzu's strategy is too clever. Whether Zhuge Liang chooses the Northern Expedition or changes his cultivation, he will eventually be dragged to death by Cao Wei. Going north, people will stay at home; Take care of yourself, your national strength is not as good as others. In a dilemma
