"Huh?" Liu Chan asked in confusion: "Why did Zhang He withdraw his troops? Why didn't he fight?"
Zhang He suddenly withdrew his troops, which puzzled Liu Chan. He also wanted to see Ma Dai fight Zhang He.
"Your Majesty!" Guo Huai said with a smile: "Zhang He has seen the Prime Minister here, so he must know that the main force of our army has arrived at Tongguan. Tongguan is a dangerous pass, and now the main force of our army is guarding it. It will not be easy for the Wei army to capture Tongguan.
”
After Guo Huai finished speaking, Zhuge Liang nodded slightly.
Liu Chan was immediately overjoyed: "Father, now that the crisis in Tongguan has been resolved, can our army command Chang'an and seize the land in Guanzhong in one fell swoop?"
Tongguan is the gateway to Guanzhong. The Han Dynasty occupied Tongguan's natural danger. It is no longer that easy for the Wei army to send troops to rescue Guanzhong.
Although the Wei army could still march into Guanzhong from Wuguan or Pubanjin Ferry.
However, when Liu Chan sent troops to Guanzhong, he had already made arrangements for these two passes. Yang Tongshan guarded Wuguan and Guo Wei occupied Pubanjin.
When the troops first arrived in Chang'an, Liu Chan divided the 15,000 new troops into four groups.
Chang'an is not the first city he captures. After all, Chang'an is located in the Guanzhong Plain. Even if he leads troops to capture Chang'an by force, he may not be able to hold it.
Because once Cao Wei learns that Chang'an has been lost, he will definitely send troops from the Central Plains to reinforce Guanzhong. Now the Han Dynasty is seeking death in a military competition with Cao Wei.
If you want to seize Guanzhong, the first thing you have to do is not to capture Chang'an, but to block Cao Wei's reinforcements. As long as Cao Wei's reinforcements cannot enter Guanzhong, the Han may still have a chance to capture the Guanzhong area. After all, before the Prime Minister's first Northern Expedition, Cao Wei
There are not many troops deployed in the Guanzhong area.
The troops from the Central Plains entering Guanzhong must enter from Tongguan, Wuguan or Pubanjin. These are the three passages from the Central Plains into Guanzhong. If these three dangerous passes are blocked, the connection between the Central Plains and Guanzhong will be cut off.
Comparing the three passes, Tongguan and Wuguan are particularly important. Although they are blocked by the pass, the Wei army can attack at any time before approaching the pass. Therefore, when dividing the troops, Liu Chan brought 5,000 new troops and gave them to Yang Tongshan's 5,000 new troops.
.
Although Liu Chan is a time traveler and has never led troops to fight in a war, as a fan of the Three Kingdoms, he still has some understanding of this era, or several passes.
Before the Prime Minister's Northern Expedition, these three passes were located in the hinterland of Cao Wei. If soldiers and horses were stationed in time, their defense would be relaxed, because they would never have imagined that the Han army would suddenly appear in front of them.
Liu Chan originally knew this period of history. Historically, Zhuge Liang's first Northern Expedition almost succeeded. The reason was that Cao Wei did not expect Zhuge Liang to send troops. At that time, the Guanzhong area did not deploy enough troops, so Zhuge Liang's army suddenly appeared in Qishan, causing Longyou to be defeated.
The three counties quickly surrendered to Zhuge Liang.
If Ma Su hadn't lost the street pavilion later, causing Prime Minister Zhuge's first Northern Expedition to fail, perhaps history would not be what we know well.
Now that the time traveler has become Liu Chan, he cannot let go of such a good opportunity, and he also knows very well that the Han wants to change his original destiny. Zhuge Liang's first Northern Expedition was a turning point.
The first Northern Expedition must succeed.
Because once the Northern Expedition fails, it will be difficult to get such a good opportunity in the future, because Cao Wei already knows that the Han army is thinking about Guanzhong, and will inevitably strengthen the defense of the Guanzhong area. Isn't this the case in history?
As the saying goes, there are only a few chances in life, and a chance to turn a bicycle into a motorcycle. Since fate has allowed me to travel through time and space and become Liu Chan, I can't live up to it.
Surprise attack on three passes and block Cao Wei's reinforcements. Even if they cannot occupy the entire pass in the end, they can at least buy more time for the prime minister to capture Longyou.
Therefore, Liu Chan and Yang Tongshan each led five thousand new troops to raid Tongguan and Wuguan, and guarded these two routes through which Cao Wei could advance into Guanzhong.
Of course, guarding Tongguan Wuguan was not a foolproof strategy, so Guo Wei was asked to lead 3,000 new troops to raid Pubanjin.
Compared with Tongguan and Wuguan, Pubanjin has its own natural advantage - the Yellow River.
Even if Cao Wei wanted to cross the river from Pubanjin and then march into Guanzhong, he had to be able to cross the Yellow River first.
Although there are not many troops in the three passes, it can still be done to cut off the connection between the pass and the Central Plains.
If Cao Zhen, Xia Houmao and others want to get in touch with Luoyang, they must send people to pass three passes before they can send the news to Luoyang. Now that all three passes are in the hands of the Han, it will be difficult for Guanzhong to easily get in touch with Luoyang.
p>
Even if an abnormality is discovered in Luoyang later, by the time Luoyang reacts, Prime Minister Zhuge may have already taken control of Longyou. By then, Liu Chan can find a way to withdraw from the three passes and return to Longyou, or Hanzhong.
What surprised Liu Chan was that he originally sent Shen Ji'an to inform Zhuge Liang, hoping that Zhuge Liang could quickly occupy Longyou without worrying about Cao Wei's reinforcements.
However, he did not care about Prime Minister Zhuge and was more concerned about the safety of his little emperor, so he led his troops into Guanzhong at night and night to rescue him, who seemed to be committing a crime.
When Liu Chan learned that Zhuge Liang had entered the military pass, he had to adjust his thinking, that is, he must defend the three passes.
Otherwise, when Cao Wei breaks through the three passes, even if the Prime Minister arrives with his troops, the Han's current military strength will simply not be able to compete with Cao Wei's cavalry in the Guanzhong Plain.
It has been exactly one month from February 28, when Liu Chan led 15,000 new troops into Ziwu Road, to today when Zhang He retreated and returned to camp.
This month felt like a century had passed for Liu Chan. On the surface, he looked as if nothing had happened, but in fact, he was always on edge, fearing that something unexpected might happen at any point.
Although he has not done a perfect job this month, he is satisfied at this moment. After all, these are troubled times, and he is just an ordinary online writer from the future world.
It’s very rare to be able to do this now.
Perhaps it was God's blessing. Although his surprise attack into Guanzhong was very dangerous, there were no major mistakes.
Unexpected, but reasonable.
Because of the surprise attack on three passes, the time for Luoyang to receive the news was delayed. Although Cao Wei responded quickly and divided his troops into three groups to reinforce Guanzhong.
Zhang He led a main force of 50,000 to attack Tongguan, Sima Yi led an auxiliary force of 30,000 to attack Wuguan, and Cao Rui led 20,000 to force the crossing of Pubanjin.
By March 29, Cao Wei's three-way reinforcements failed to successfully break through the barrier.
Not to mention the Tongguan guarded by Liu Chan, because Liu Chan prepared lime in advance and Zhang He suffered heavy losses. Now that Zhuge Liang has arrived at Tongguan, Zhang He's journey has basically been solved.
Let’s talk about Sima Yi, who assisted the attack. He has not yet reached Wuguan with any of his soldiers, because he is still busy dealing with the rebel general Meng Da.
Liu Chan knew this beforehand.
There are records in history that on the eve of the first Northern Expedition, the prime minister learned that Meng Da wanted to surrender, so he sent someone to contact Meng Da and persuade him to surrender in time. However, Meng Da was capricious, wavering from side to side, and delayed in deciding to surrender.< /p>
So Zhuge Liang used a trick to leak Meng Da's plan to rebel against Wei and return to Han to Shen Yi, who was at odds with Meng Da, forcing Meng Da to return to Han as soon as possible.
The result of history is very simple. Shen Yi exposed Meng Da's rebellion, and Sima Yi's troops arrived in Xincheng on the 8th to put down the rebellion, and finally destroyed Meng Da.
Regarding Meng Da's rebellion from Wei and his return to Han, there were various comments from later generations, but Liu Chan would not care about this now.
Because in his opinion, he can definitely take advantage of Meng Da's return to the Han Dynasty.
After all - the opportunity is rare.
