Since the sixth day of Zhuge Liang and Jiang Wei's joint order to start the war, it is also the time when Sima Yi retreats to Guangzong City.

On this day, Deng Ai's 8th Changsheng Division stationed in Nanyang, Tun, and He Jing's 15th Zhaoyi Division stationed in Xuzhou, Tun, all drove north.

There were intermittent rail cars to assist in transportation, and there were also military stations along the way to do supplies, so the progress at the beginning of the march was rapid.

Since the start of the war, Zhuge Liang took over the command of the successor army to the east, with Wei Yan as the vanguard general, the veteran He Qi as the deputy general of the army, Zhuge Liang himself will be responsible for the command of the plain area east of the Taihang Mountain after crossing the river with the successor army, and is the commander of the East Road; Yanzhou Mu Xu Shu and Qingzhou Mu Pang Lin are responsible for organizing the transportation of logistics supplies.

The entire Eastern Route Army has the 12th Dangkou Division, the 13th Expeditionary Division, the 14th Zhaoren Division, and the 15th Zhaoyi Division; and twice the size of the county soldiers, conscription of the people.

The biggest task of the Eastern Theater, which lacked cavalry strength, was to contain the main force of the Wei army in the plain area; and revealed the disadvantage of the lack of cavalry, attracted the Wei army, and gave the Wei army an illusion of hope for victory, so as to entangle and buy time for the other three armies to act.

Not to give the east a large-scale cavalry, naturally there is a comprehensive consideration.

In the campaign to destroy the country, military issues can no longer be considered alone, and it is all the more necessary to make political concessions.

It was the Western Route Army and the Central Route Army where the Guanlong Corps was located to deal a fatal blow to the Wei State, and only in this way could the main force of the Wei Army be left in the Hebei Plain, and then swallowed in one bite, so as to achieve the strategic goal of destroying the country in World War I.

Otherwise, if it can't be cleaned up, the monarchs and ministers of Wei will flee north, and the nomadic forces of the six towns of Youyun will inevitably become a major disaster on the border. Although there was no concern that the Wei army would be able to counterattack the Central Plains, this would greatly hinder the post-war recuperation.

However, the Guanlong area already has a mature pastoral plan, and if the Han tribes are transported and migrated to the Central Plains, some of the gains outweigh the losses.

There are no mature horse farms in the Central Plains, and the pastures in the Lianghuai region are on the right track, and it is not enough to provide a large number of war horses to the Central Plains, so the Central Plains objectively does not have the conditions to form a formed cavalry.

In this way, Guan Long's cavalry forces could be used intensively to obtain the absolute field advantage of the Shanxi battlefield.

The commander-in-chief of the Shanxi battlefield of the Wei army is Cao Zhen, how many cavalry does Cao Zhen have?

If there is not enough cavalry, he will not dare to fight in the field.

If you don't dare to fight in the field, you will lose control outside the city, and you can only let the government soldiers run rampant.

The current cavalry is no longer the cavalry of the late Han Dynasty and the heroic period, and the precipitation and development of these years, the new cavalry equipment has been fully equipped, and the tactics of the new cavalry have stimulated the development in the dark clouds of war.

Thanks to the legendary heavy combination of Tian Xin and Mondo, the new cavalry of both sides has taken reloading as the main direction of development.

The traditional lightly armed, medium-mounted infantry, and crossbow troops, which were conceptually restrained by cavalry, were all restrained by heavy cavalry.

Whoever has more heavy cavalry will have a big advantage on the battlefield.

This is already the consensus of the officers of both sides, and in the absence of heavy cavalry, or the disadvantage of heavy cavalry, the officers will avoid field battles.

The protagonist of the war seems to have transitioned from heavy infantry to heavy cavalry.

Therefore, the Wei army in the Shanxi battlefield abandoned the periphery and retreated step by step and concentrated on a few main strongholds in preparation for long-term defense; After the Wei army shrank back to the wall, the government soldiers advanced smoothly.

Naturally, at the moment of advocating the strength of heavy cavalry, Zhuge Liang's Eastern Route Army was at a great disadvantage on the books, and it seemed that it would be dangerous to have a field battle.

As if sending a big dumpling to Sima Yi, this is the greatest significance of the current existence of the East Route Army.

Whether Sima Yi can swallow this dumpling, or choke to death by this dumpling, has nothing to do with Guan Long for the time being.

All the pieces have been smashed out, and no one can go back and make adjustments.

In order to facilitate the compilation of information from all parties, Tian Xin's command base camp was transferred to Tongguanxi Station.

At this moment, Jiang Wei had crossed the river from Hongnong to the north, and had led Hongnong's troops to the north to climb Zhongtiao Mountain, and would make a momentum to attack Anyi in order to confuse the Wei army.

And Wang Ping, Ma Dai, Yao Ge, and Yang Qianli will rely on the mobility and deterrence of pure cavalry troops after crossing the river at Fengling, and directly pass through Puban, an important town on the front line of the Wei army, to join Jiang Wei.

After the convergence, this combined infantry and cavalry force of 30,000 will maneuver with Cao Zhen in the Anyi area, waiting for the action of the Huya Division led by Xie Jing, and the Huya Division will march along Fenshui to cut off Cao Zhen's retreat to Taiyuan.

As long as the retreat route is cut off, the troops assembled in the pass will rush forward, causing a great local advantage.

Then the old man crossed the river and returned to his hometown with the strongest posture in the world, which was enough to disintegrate the Wei strongholds around Anyi and the defenders of the Acropolis.

With the initiative in the war in hand, the war takes place in the territory controlled by the enemy, and the battlefield can be divided with superior forces.

Of course, if one of the links in the follow-up troop movement falls off the chain, it will naturally be eaten by the defenders; At the same time, the most fierce is the first half month.

In this half month, the supplies are sufficient, and the sergeants are perennial to maintain fat, endure expeditionary treks, and endure all kinds of tosses. This was the elite edge at the beginning of the war, and the Wei army naturally had to shrink and dodge in order to wait for the government soldiers to show fatigue.

If the situation cannot be opened after half a month, the sergeant's patience will decline and produce war weariness and resistance, and the most important logistical problem will become more and more prominent. The longer it is put on hold or delayed, the more dangerous the logistical problems become.

Therefore, within half a month of the start of the war, the Shanxi battlefield must achieve two goals.

One is to block Cao Zhen's passage to Taiyuan, and the other is to open up Pusaka.

Capture Pusaka, and the government soldiers in the Hedong battlefield will receive stable supplies; And pulling out Kasaka to open up the supply node can boost the morale of all armies.

In this case, on the eighth day of the battle, Guan Yu arrived at Tongguan and would cross the river to participate in the battle.

At this moment, the old man's beard was dyed white, and he was followed by Xue Rong, who Tian Xin was familiar with, and the other close attendants were all newcomers that Tian Xin didn't know.

The current old man boarded the boat directly and was reluctant to talk to him, so Tian Xin had to have a banquet with Xue Rong by the dock.

Xue Rong is no longer the energetic general of the 'Micheng Qianshantun' at the beginning, but now he is a middle-strong general with a deep bearing, and he is also the father of seven or eight children.

In two years, with the current early marriage customs, Xue Rong will also be a grandfather, and he can call himself an old husband with confidence.

In the past, the soldiers of the Jingzhou army were either killed in battle, or the sky was separated, and now Tian Xin has always kept Luo Qiong's Eagle Yang Division by his side to relieve boredom; Even the old Yi Barracks in Lingnan were recruited into Guanzhong one after another, staying by his side as attendant military attachés.

Facing a group of strange newcomers will make Tian Xin a little trance-like and blur his emotional perception.

Only the old person in his memory can make him accurately feel his emotional changes, and every old person is a fragment of memory.

Now that Xue Rong is sent across the river, Tian Xin is reluctant but also very worried about his father-in-law's mental state.

Now the old man is all supported by the obsession of returning to his hometown, and it is likely that the trip back to his hometown is a point of no return.

It's a pity that Guan Ping is in Hetao, and Guan Xing is still guarding the southeast, so he can't come out to see him.

In addition to Xue Rong, who can accompany his father-in-law to cross the river, Amu is left.

Xue Rong is also aware of Guan Yu's specific condition, not only sad for Guan Yu's aging and approaching deadline; I also feel lost in the long-term future.

Guan Yu, who had already boarded the ship, was in a green robe and gold armor, the armor was a loose leather armor richly decorated with gold dust, and his eyes were stunned when he sat on the Taishi chair on the deck, staring at the distant wolf smoke to the north.

Through the hazy smoke, Guan Yu could barely recognize that it was an important ferry port connecting Hedong to Guanzhong, Pubanjin.

Tian Xin, who came to see him off, couldn't board the ship, but his righteous son Xiahou Ping still got on the boat, his face was calm at the moment, listening to Guan Yu's instructions on various matters, as if his last words.

And Pei Jun, who accompanied him, took a pen to record, cautiously, and did not dare to omit the slightest.

Although Guan Ping was activated, he was still in exile and stayed outside the fortress, even if he wanted to come back, Guan Yu couldn't let go of his face to see him; Guan Xing is simpler there, and he doesn't want Guan Xing to come back to stir up the matter of replacing the old and the new.

No one knows who will suddenly jump out of the way when the old and the new are replaced.

Therefore, keeping Guan Xing in the southeast is a good protection, and there is no need to be bloodstained or embarrassed. When Guan Xing came back to his senses, the person who should be dealt with was dealt with, and he had no chance to intercede or entangle.
