Yanghu chose to march to Jinyang from the nearest route, this road Liu Yin is certainly not unfamiliar with, because from Jinyang to Shangdang, the Shu army fought from this road, and Niexian County is still the first county town conquered by the Shu army after entering Shangdang. Pen, fun, pavilion www. biquge。 info

However, since the Jin army has taken this road, Liu Yin will not be able to follow the Jin army's ass anyway, and follow suit, first of all, this is not Liu Yin's style, and secondly, in Liu Yin's heart, there is a bigger plan.

All roads lead to Rome, and there is more to Jinyang than this.

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

Hedong County does not belong to the state, in the Eastern Han Dynasty under the jurisdiction of Sili Xiaowei, is one of the three important places of Gongwei Jingshi. During the Cao Wei period, it was under the jurisdiction of Sizhou, and in the eighth year of the Wei Dynasty, the twelve counties in the north of Hedong County were Pingyang County, but customarily, Hedong County and Pingyang County were still collectively called Hedong District.

Hedong County has a flat terrain, fertile land, and a large population, and has always been a more important county in the Cao Wei regime, after Liu Yuan rebelled, he has always attached importance to the strategy of Hedong County, Liu Yuan even once had the intention of moving the capital to Pingyang, but because the Shu army entered the Shangdang, Liu Yuan had to spare time and energy to deal with the Shu army, and he was lax for Hedong County, so that although the Huns controlled most of the counties of Hedong County, they never took Pujin Pass.

Pujin Pass is the most important link in the entire Hedong defense system, from the Shu army occupied Guanzhong, the Jin State regarded Pujin Pass as a base to prevent the Shu people from crossing eastward and preparing to counterattack the attack, and Hu Fen, the assassin of the state, was transferred to Pubanlai, as the governor of Hedong, trying to force the Yellow River from Pubanjin and march into Guanzhong.

However, the failure of the two river crossings completely lost hope for the Jin army, and the combat mission of the entire Pubanjin shifted from strategic offensive to strategic defense.

However, for this Yellow River natural danger, although the Jin army could not be overcome, but the Shu army wanted to fight, it was by no means so easy, this confidence, Hu Fen who was defending Pujin Pass at that time still had.

But then the rebellion of the Huns followed, and Hu Fen was ordered to rush back to Bingzhou to quell the rebellion, and handed over the defense of Pujin Pass to Sima Jun, the 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 became the emperor, he was named the king of Ruyin, a high and powerful position, and he can be regarded as a representative of the real power faction in the Sima family.

Although Sima Jun is the youngest among the sons of Sima, his talent and knowledge are not bad at all, although he is not at the same level as Sima Zhaolai, but he is much stronger than Sima Gan and Sima Liang, so Sima Yan still sent Sima Jun to serve as the governor of Hedong at a critical time, responsible for the defense of the two counties of Hedong and Pubanjin.

Hu Fen went north to merge the state, but was defeated and died in less than half a month, and the entire state fell into the hands of the Huns, and the two counties in Hedong also bore the brunt and became the target of the Huns' invasion in the south.

Sima Jun in this case, the governor of Hedong, can be said to be in danger of the order, and now the whole country is tense, Sima Yan can send his men and horses, is also extremely limited, the original Pubanjin garrison has 50,000 people, the battle across the river suffered a lot of casualties, Hu Fen also took some when he left, although Sima Jun did not come alone when he arrived, but the entire Hedong County people combined, only 30,000 people.

This bit of soldiers and horses, if scattered to the two counties of Pingyang in Hedong, does seem too thin, and it is powerless to deal with the attack of the Huns, so Sima Jun simply gave up the defense of the two counties in Pingyang and Hedong, and threw the two counties of Pingyang Anyi and dozens of county towns to the Huns, and he shrunk all the 30,000 soldiers and horses and held the Pujin Pass.

The terrain of Pujin Pass is dangerous, leaning on the Yellow River, the north and south mountains are sandwiched, it is a natural dangerous pass, Sima Jun has to build fortifications within ten miles around Puban, in order to block the attack of the Huns.

After the Huns took the two counties of Hedong, they naturally set their sights on Puban, as long as they could take the Pujin Pass, it would be equivalent to opening another door, creating conditions for the Huns to cross the Yellow River and march into the pass.

Of course, now the Huns do not have the strength to attack Guanzhong, first of all, it is more difficult to force the Yellow River, the Jin army tried to cross the river twice, concentrated a large number of ships and men and horses, all unsuccessful, the Huns a nation on horseback, only riding horses and archery, want to cross the river, try to climb to the sky.

However, even if the Huns have the ability to cross the river now, it is impossible to try, because the current strategic focus of the Huns is still maintained in the area of Hedong and Hebei, and the Jin State is still their biggest enemy.

But even if the Huns did not plan to cross the river and take Pubanlai, that is, in order to eliminate the last Jin army in Hedong, after all, Sima Jun's army stayed there, which was an extremely unstable factor for the Huns to control Hedong.

Liu Yuan appointed the general Hu Yanyu as the Taishou of Hedong and led 50,000 troops to attack Pujin Pass.

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

Sima Jun guarded Pujin Pass for two years, and this battle was fought for two years, although the number of Jin troops dropped from 30,000 to more than 20,000, but it never wavered Sima Jun's determination to stick to Pujin Pass.

The defense of Pujin Pass was also very hard, Huyanyu failed to attack several times, and adopted the tactics of long-term siege, although the terrain of Pujin Pass was complex and dangerous, but on the whole, it was too narrow, Huyanyu took advantage of this to cut off their grain route and force Sima Jun to surrender.

However, as the first fortress in Hedong, Pujin Pass is naturally full of grain and grass, and there is no problem in holding on for two years, and Huyanyu's plan did not work.

Hu Yanyou finally gave up attacking Pujin Pass, because he received Liu Yuan's order to lead the army to retreat to Jinyang, because of the failure of the battle of Shangdang, Liu Yuan also had to adjust the strategic deployment, the Xiongnu scattered in various places to Jinyang, wanting to fight to the death with the Jin Shu army in Jinyang.

Therefore, the entire Hedong area has become an empty city, and after Liu Yin crossed the Taiyue Mountain from Guyuan into Hedong, he effortlessly took Pingyang and Anyi.

It stands to reason that if you want to attack Jinyang with the Jin army on two sides, this is the best time for Liu Yin to march, however, Liu Yin has no intention of marching north, after occupying Anyi, Liu Yin personally led the army to look southwest, pointing at Pujin Pass.
