The last three kingdoms

Chapter 847 Ruyin King Sima Jun
Yang Hu chose to march to Jinyang from the nearest route. Of course, Liu Yin would not be unfamiliar with this road, because from Jinyang to Shangdang, the Shu army came from this road, and Nie County was the place where the Shu army entered Shangdang. The first county seat conquered after the party.

But now that the Jin army has gone this way, Liu Yin can't follow the Jin army's ass anyway, and follow suit. First of all, this is not Liu Yin's style, and second, there is a bigger plan in Liu Yin's heart.

All roads lead to Rome, and going to Jinyang is far more than this road.

Compared with Shangdang, Liu Yin is more eager to win Hedong County.

Hedong County did not belong to Bingzhou, but was under the jurisdiction of Sili Xiaowei in the Eastern Han Dynasty, and it was one of the important places in Sanhe to defend the capital.During the Cao Wei Dynasty, it was under the jurisdiction of Sizhou. In the eighth year of Wei Zhengshi, the twelve counties in the north of Hedong County were analyzed as Pingyang County.

Hedong County has a flat terrain, fertile land, and a large population. It has always been a relatively important county in the Cao Wei regime. After Liu Yuan's rebellion, he has always attached importance to the strategy of Hedong County. When the Shu army entered Shangdang, Liu Yuan had to spare time and energy to deal with the Shu army, but he was slack about Hedong County, so that although the Huns controlled most of the counties in Hedong County, they never took Pujin Pass.

Pujin Pass is the most important link in the entire Hedong defense system. Since the Shu army occupied Guanzhong, the Jin State regarded Pujin Pass as a base to prevent the Shu people from crossing eastward and prepare to counterattack the pass. Hu Fen, the state governor He was transferred to Puban and served as the governor of Hedong, trying to cross the Yellow River from Pubanjin and march into Guanzhong.

However, the failure of crossing the river twice made the Jin army completely lose hope, and the entire combat mission of Pubanjin was transferred from strategic offense to strategic defense.

However, as far as the natural danger of the Yellow River is concerned, although the Jin army cannot overcome it, it is by no means an easy task for the Shu army to fight over. Hu Fen, who was defending Pujin Pass at that time, still had this confidence.

But then the Huns rebelled one after another, Hu Fen was ordered to rush back to Bingzhou to quell the rebellion, and handed over the defense of Pujin Pass to Sima Jun, king of Ruyin.

Sima Jun is the seventh son of Sima Yi, the half-brother of Sima Shi and Sima Zhao, and the uncle of today's son Sima Yan. After Sima Yan proclaimed himself emperor, he was named King of Ruyin. A representative of the real power faction in the Sima family.

Although Sima Jun is the youngest among the Sima masters, his talent and knowledge are not bad at all. Although he is not at the same level as Sima Zhaolai, he is still much better than Sima Gan and Sima Liang. At that time, Sima Jun was still sent to serve as the governor of Hedong, in charge of the defense of the two counties of Hedong and Pubanjin.

Hu Fen went north to Bingzhou, and was defeated and died within half a month. The whole Bingzhou fell to the hands of the Huns, and the two counties of Hedong also bore the brunt of it, and became the targets of the Huns' southward invasion.

Under such circumstances, Sima Jun served as the governor of Hedong, and he was ordered in the face of danger. Now that the whole country is tense, the number of troops Sima Yan can send to him is also extremely limited. It turns out that Pu Banjin's garrison has 5 people Hu Fen took some of them with him when he left. Although Sima Jun did not come alone when he took office, the total number of troops in Hedong County was only [-].

If these soldiers and horses were scattered to the two counties of Hedong and Pingyang, it would indeed be too thin, and it would be too weak to deal with the Huns' attack, so Sima Jun simply gave up the defense of the two counties of Pingyang and Pingyang, and put the two counties of Anyi in Pingyang together. Dozens of county towns were all thrown to the Huns, and all [-] soldiers and horses were retracted by themselves, and they stood firm at Pujin Pass.

The terrain of Pujin Pass is dangerous, backed by the Yellow River, and surrounded by two mountains in the north and south. It is a natural and dangerous pass. Sima Jun built fortifications within ten miles around Puban according to the dangerous points to prevent the Huns from attacking.

After the Huns lightly captured the two counties of Hedong, they naturally turned their attention to Puban. As long as they can win Pujin Pass, it will open another door and create conditions for the Huns to cross the Yellow River and march into Guanzhong.

Of course, the Huns do not have the power to attack Guanzhong. First of all, it is difficult to cross the Yellow River. The Jin army tried to cross the river twice and concentrated a large number of ships and horses, but failed. The Huns are a nation on horseback. , can only ride horses and archery, want to cross the river, try to reach the sky.

But even if the Huns are able to cross the river now, it is impossible to try, because the current strategic focus of the Huns is still in the Hebei area, and the Jin State is still their biggest enemy. Only by capturing Luoyang and defeating the Jin State, Only then did the Huns have plans to continue to expand outward.

But even if the Huns had no plans to cross the river and took Puban, it was to destroy the last Jin army in Hedong. After all, Sima Jun's army stayed there, and it was extremely unstable for the Huns to control Hedong. factor.

Liu Yuan appointed general Hu Yanyou as the prefect of Hedong, and led [-] troops to attack Pujin Pass.

After Hu Yanyou arrived in Anyi, he led his troops to besiege Pujin Pass several times. Relying on the dangerous pass, Sima Jun held on for a long time to ensure that Pujin Pass was not lost.

Sima Jun guarded Pujin Pass for two years, and this battle lasted for two years. Although the number of Jin troops dropped from 3 to more than 2, Sima Jun's determination to stick to Pujin Pass never wavered.

The defense of Pujin Pass was also very difficult. Huyanyou's several strong attacks failed, so he adopted the long-term siege tactics. Although the terrain of Pujin Pass is complex and dangerous, overall, it is too narrow. Taking advantage of this, they cut off their food supply and forced Sima Jun to surrender.

However, as the number one fortress in Hedong, Pujin Pass is naturally full of food and grass, and there is no problem in sticking to it for two years. Hu Yanyou's plan did not work.

Hu Yanyou finally gave up attacking Pujin Pass, because he received Liu Yuan's order and led his army to retreat to Jinyang. Because of the failure of the Battle of Shangdang, Liu Yuan also had to adjust his strategic deployment and send the scattered troops to Jinyang. The Huns gathered in Jinyang, intending to fight to the death with the Jinshu army in Jinyang.

So the entire Hedong area became empty cities. After Liu Yin crossed Taiyue Mountain from Guyuan and entered Hedong, he took Pingyang and Anyi without any effort.

It stands to reason that if he wants to attack Jinyang from two sides, it is the best time for Liu Yin to march. However, Liu Yin has no plans to march north. After occupying Anyi, Liu Yin personally led the army to see Going southwest, point your sword at Pujin Pass.
