Decision-making in temples often needs to be viewed from the outside to the inside.
This prompted the State of Wei to first appoint Liu Bao, a member of the Southern Huns' left faction, as the Protector of Shuofang, and later changed the title of him and Liu Gaosheng to be King of Hunxie. The reason for not killing the King was not just the superficial attack on Hexi.
The territory of Wei is vast and densely populated, and many of the princes gathered in the Luoyang temple are wary of danger in times of peace.
Therefore, they also gradually realized that the Southern Xiongnu who were originally divided into five tribes by Wei Wu and Cao Cao and migrated to Bingzhou, Liu Bao, the Xian King of Zuo, had a faint tendency to become powerful.
Because in the tradition of Xiongnu's accession to the throne, Liu Bao was the first successor to the throne of Shanyu.
As King Youxian, who was in charge of the country, went to bei and grew old, Sima, who supervised the affairs of various ministries, was gradually ostracized, and many Xiongnu tribesmen began to turn to Liu Bao one after another.
After all, it was not uncommon in the history of the Huns to kill their fathers and brothers to seize the throne.
Those Xiongnu people who were determined to change their status and hope to become nobles attached themselves to Liu Bao in advance, and they were also preparing in advance for hope.
Worried that if Liu Bao continued to become powerful, the Luoyang Temple might unite the Southern Huns into one, so they used the war to move their tribe far away from the heart of Bingzhou.
As for why Liu Gaosheng Yuan, the son of Youbu Qubei, was also transferred to Hexi.
The way for an emperor to control his subordinates is to check and balance!
After serving as a lowly prisoner of the Xiongnu court for many years, how could his son not want the support of Wei to inherit this power?
As a result, there will inevitably be an irresolvable conflict with Liu Bao.
This is one of the reasons why Fei Yao did not use Deng Ai's advice.
Before he came to the south of Helan Mountain, Sima Yi privately told the Luoyang Temple to bring together the Xianbei Tuoba tribe and Liu Gaosheng, the right tribe of the Southern Huns, to fight against Liu Bao's left tribe.
Only such continuous differentiation can ensure that the southern Xiongnu will not unite again and avoid becoming a major trouble for Wei's northern frontier in the future.
For example, Liu Bao was clearly canonized as the Hunxie King, and Liu Gaosheng Yuan was the King of Xiutu. However, during the war arrangement, Liu Bao was ordered to move to Xiutuze; while Liu Gaosheng Yuan and Tuoba Li moved to Juyan.
Ze. Deliberately messed up the old fiefdoms, so as to plant the factors of conflict between the two of them in advance.
Yes, the responsibilities of each department have been clearly defined.
Xiutuze and Juyanze, which require crossing the desert or semi-desert, can only be reached by nomadic tribes with no fixed settlements; and Fei Yao's attack areas are the counties on the east side of Wuwei County, and the disconnection between Hexi and Hexi.
Yincheng Fortress’s communication.
Because of this strategic planning, Wei's main attack point was the Fortress of Anyin.
If it can be captured, it will become an outpost for the Wei State to march to Hexi; if it cannot be captured, it will be surrounded and the Han army in Longyou will be forced to come to rescue, and the plan of exhausting the troops will be successful.
Naturally, it is difficult for cavalry and soldiers to attack difficult tasks.
But this was not something Fei Yao needed to worry about, and it was another reason why he did not use Deng Ai's advice.
The army of Wei General's expedition to Hexi did not stop at the Guanzhong Jingqi. There were also 20,000 troops from the left and right groups of the Southern Xiongnu and the Xianbei Tuoba tribe under the command of Xia Houru!
Xia Houru, who was restored to the position of General of the Northern Campaign, is currently stationed in the newly restored Jiuyuan County.
The soldiers and horses under his command were the soldiers previously used by the Wei State to guard the northern border.
After the Xianbei adults Ke Bineng and Bu Dugen, and the Liaodong Gongsun clan were all destroyed, the northern frontier of the Wei State, regardless of the Xianbei, Wuhuan, Zahu and other tribes, the strong ones fled far to Mobei, and the weak ones surrendered. Now it has become
There is no war.
In the past, there were an extremely large number of soldiers who guarded the frontier for thousands of miles.
It is not difficult to allocate 20,000 troops from them and put them under the command of Xia Houru.
Otherwise, it was just to disturb the land west of Helan. Why would Sima Yi use his trusted generals Hu Zun and Deng Ai to lead seven or eight thousand soldiers to farm south of Helan Mountain?
This was the reason why Sima Yi went to Luoyang to tell Luo Yang about his plan to recapture Hexi and Longyou, and asked Cao Rui to transfer Xia Houru to Bingzhou. It was also the hidden back-up plan.
Not to mention that the Han army could not have expected that the soldiers who used to guard Youzhou would come all the way to the Fortress of Guanyin. Even the Dukes of Wei Guo Temple, Gungun, knew that few people knew that the soldiers from northern Xinjiang would participate in the Battle of Hexi - - In everyone's eyes, Cao Rui asked Xia Houru to go to Jiuyuan County just to ensure the stability of the newly restored counties of Yunzhong, Jiuyuan and Shuofang.
Or, in other words, after learning from the past experience of Cao Zhen's repeated attempts to recapture Longyou, Sima Yi felt that without an unexpected "surprise", it would be difficult to win with a serious army.
In particular, the morale of the main force in Guanzhong was worrying, and they were all exposed under the eyes of the Han army, making it difficult for them to make surprise moves.
Of course!
Neither Sima Yi nor Cao Rui pinned their hopes of seizing Hexi and Longyou on the left and right tribes of the Southern Xiongnu and the Tuoba tribe of Xianbei.
How can those barbarians accomplish anything evil?
At best, it's just a pretense to disperse Ni Shu's forces and confuse Ni Shu's deployment and scheduling!
As for the huge cost of moving troops from Youzhou, and the high treatment required to ensure the morale and fighting spirit of the soldiers, why can Cao Rui accept it?
He had no better way.
When Sima Yi wrote the above table, he also attached the responses and plans of both sides in the many battles since the Han army came out of Longyou.
From this appendix, we can see that Cao Zhen’s repeated use of troops was too righteous!
However, the Han army's unexpected move out of Longyou, their thousands-mile attack to seize the fortress of Guanyin, and the virtual and real tactics they used in the battle of Lingju all resulted in a miraculous victory!
"I secretly thought that when we sent troops to Longyou or Hanzhong from Guanzhong, we did not have the advantage of the terrain, so we would get half the result with twice the result! For now, the offensive and defensive positions of Wei and Shu have changed! If we had not planned this early, we would have allowed the other to rebel against Shu for several years. Time to cultivate health and recuperate, and expand the recruitment of cavalry and martial arts. I am afraid that not only will it be difficult for the Wei State to regain Longyou in the future, but the land in Guanzhong will also be unsafe like the previous dynasty during the Qiang chaos in Liangzhou! Therefore, the veteran thought of this plan in order to break the situation. Count. If God's wishes come true, our Wei State can break through the fortress of Manyin, and then invade the Hexi Corridor to regain Liangzhou and advance to Longyou; if not, Xiahou Junlin will lead the army to besiege Manyin, and the governor of Guo Boji will go north to support him, and he will be able to force the enemy. If the soldiers against Shu come out from Longyou to rescue us, our Wei State can offset the disadvantage of the unfavorable terrain! If the soldiers against Shu come out, the veterans will use their troops to force Hanzhong Baoxiegu and Wudu to disperse, making it difficult for them to take care of themselves! I hope your Majesty will check it out!"
At the end of the above table, Sima Yi said this.
After seeing this, Cao Rui, who was resentful about losing Longyou first and then Liangzhou, pondered alone for several days, and finally thought of using weapons again.
Anyway, if there is a war between Jingxiang and Huaiyou, there are still elite Chinese troops stationed in Luoyang who can rush to help.
And he thought to himself that judging from Sun Wu's offensives in recent years, there should be no danger.
Therefore, he very cautiously sent a letter to Sima Yi that day, asking if he could mobilize troops from Guanzhong.
Otherwise, if the war in Hexi is just disturbing, and the main force huddled in Guanzhong does not participate in the war, why can't three to five thousand troops be mobilized to join the crisis?
