After returning to Shangdang, Liu Yin did not make any stops, and immediately waved his army south, from Huguan to Gaodu. Pen, fun, and www.biquge.info

Gaodu is currently the southernmost city controlled by the Shu army in Bingzhou, and after passing Gaodu, it entered Hanoi County, which was controlled by the Jin State.

Although this is the junction of the two sides, because the center of gravity of the battle between the two sides is currently in Jizhou, the Jin State does not have too many defensive forces in Hanoi.

The entire north of the Yellow River belongs to the defense area of the rebel Metropolitan Governor Yanghu, and Hanoi County is no exception, Yanghu has concentrated almost all his forces in Yecheng, and the defense of Hanoi County is naturally relatively empty.

Liu Yin made a detour to attack Hanoi this time, and he did it very secretively, and he did not leak the news to the outside world as much as possible. Although Yanghu's trench tactics effectively blocked the attack of the Shu army, it cut off his control of the news from the outside world.

And Liu Yin doubled all the way and maintained a high marching speed, in order to catch the Jin State off guard in Hanoi.

The terrain of Bingzhou is high, out of the high capital to the south, is the vast plain of Hanoi, the Shu army has been from a high position, roaring down, overnight, it surrounded Shanyang City.

Shanyang City was only garrisoned by a thousand people, and the guard general really saw the Shu army attacking, and was so frightened that he opened the city and surrendered without the slightest resistance, and the Shu army took Shanyang lightly and opened the door to Hanoi.

The sudden appearance of the Shu army in Hanoi made the Jin court panic, Hanoi County was the only barrier to the north of Luoyang, once Hanoi was lost, Luoyang would be in danger. Therefore, as soon as he heard that the Shu army had captured Shanyang, Sima Yan was restless, and urgently ordered Dong Ai, the Taishou of Hanoi, to ask for it, and ordered Yanghu to send troops to reinforce him.

Hanoi Taishou Dong Ai originally did not have many soldiers, and most of them were county soldiers who lacked combat effectiveness, and the Tiger Cavalry Army, the Tiger Bu Army, and the Yongan Army of the Shu Army were not the division of the tiger and wolf, Dong Ai was not an opponent at all, and fought a battle with the Shu army in the shooting dog, and the result was that the whole army was destroyed, Dong Ai died in the chaos, and the Shu army marched south and captured the county of Hanoi County.

In the next few days, the Shu army ran rampant in Hanoi, as if entering a no-man's land, several cities of Liankeyewang, Wenxian, and Heyang approached the Xiaopingjin ferry.

The Luoyang government and the opposition up and down, as if they had experienced an eight-magnitude earthquake, shook violently, Sima Yan sat like pins and needles, and hurriedly dispatched soldiers and horses near Luoyang to Xiaopingjin Pass to strictly guard against death.

Xiaopingjin Pass is located in the north of the Yellow River on the south bank of the Yellow River, only thirty or forty miles away from Luoyang City, once lost, it will be equivalent to a catastrophe for Luoyang, so Sima Yan will never dare to ignore it. Luoyang surface mountains and rivers, eight passes to hold, this small Pingjin Pass is one of them, and the Mengjin Pass in the northeast of Luoyang is the angle of each other, a total of the Yellow River natural risk.

A few years ago, the Xiongnu invaded the border, and also had troops in Xiaopingjin Ferry, at that time in Luoyang also caused a violent shock, and even many ministers proposed to move the capital to avoid the Huns' edge, until later, Yanghu sent troops to Hanoi to repel the Huns, which calmed down the situation.

Now the Shu army is in Xiaopingjin, the uproar brought is no less than the Huns at that time, and the state has been lost, the situation in Jizhou is difficult, and now the Shu army is in the Yellow River, and the entire Jin Dynasty's rivers and mountains are in danger. Up and down Luoyang, there is a flood of sorrow, and despair spreads in the capital.

Sima Yan urgently summoned the ministers to the palace to discuss the plan to retreat from the enemy.

"Ladies and gentlemen, now that the Shu people are already in the Yellow River, Luoyang is in danger, I can't sleep and eat, what are your strategies, can you share your worries with me?" Sima Yan looked at the civil and military officials below, and opened his mouth to ask.

Civil and military officials, look at me, I look at you, all look at each other, if the Shu army is really easy to retreat, why should the Jin State lose its troops and lose the city and lose the land, the battle has reached this point, the Jin State is already weak, and the generals who can really lead the troops to fight are either already on the front line or have been killed and martyred. These ministers above the court are usually stable officials, and at this time, who can come up with any ideas, they are all silent.

Sima Yan swept around, so many ministers turned out to be unexpectedly unspoken, he couldn't help but be a little angry and said: "I am a high-ranking official who raises you, and you talk about pedants and celestials on weekdays, so now all of them have become mute?" What do you say I want you to do? ”

Jia Chong, who was standing in the first place, obviously had some trouble on his face, he was Situ at the head of the hundred officials, and he also led the Shang Shuling, if he didn't open his mouth again, it would really be unreasonable. Jia Chong stepped forward and bowed to the wat and said: "Your Majesty is angry, the Shu soldiers are on the Yellow River, and the soldiers of Luoyang should only refuse to defend at Xiaopingjin Pass, and they must not easily cross the river to attack in the north. ”

Sima Yan nodded, and also thought deeply, the strength of Luoyang is the real foundation of the country, how dare to easily mobilize, if you cross the north from Xiaobeijin to attack in the north, not to mention whether you can win, Luoyang's defense is bound to be empty, if Luoyang has no soldiers to defend it, Sima Yan will not have a sense of security, this is of course unacceptable to Sima Yan, if he wants to retreat from the enemy in Hanoi, he can only mobilize soldiers and horses from other counties.

In the past few years, the total number of troops of the Jin army has deteriorated, and the combat effectiveness has decreased sharply, and the division has lost its territory.

Now Sima Yan's only hope is Yecheng's Yanghu, although Ma Long's army defeated Qinghe and withdrew to Qingzhou, but Yanghu's hands still have 100,000 troops, which is also the only force of the Jin army north of the Yellow River, and if you want to solve the crisis in Hanoi, only Yanghu can send troops.

"Didn't I already give an order to Yanghu, why hasn't he sent troops yet?" Speaking of Yanghu, Sima Yan remembered that he had given Yanghu an order a few days ago to send troops to rescue Hanoi, at that time, Hanoi was too guarded Dong Ai had not been killed, and the situation in Hanoi was not so bad, but with the death of Dong Ai, the situation in Hanoi completely collapsed, and the Shu army swept wantonly in Hanoi County, if it entered a no-man's land, it was not just no soldiers to resist, if Yanghu could send troops earlier, why was the situation in Hanoi like this?

Cao Shangshu, the soldier in charge of military affairs, hurriedly went out and said: "Your Majesty, the edict sent to Yecheng was sent out a few days ago with a 600-mile expedited horse, and the person who delivered the edict has now returned to Luoyang, and the edict is confirmed to be correct. ”
