Just when Li Yu was discussing with a group of generals how to break Jincheng, the Eastern Route Army led by Heiya Changzhi, who was heading south from the east coast of Silla, captured Youlin County and approached Yeseong-gun, perhaps in two or three days, he would join forces with Li Yu at Jincheng.

At the same time, Liu Renyuan, the governor of the Xiongjin Prefecture who had been preparing for a long time, led more than 10,000 troops to cross the river and fought with 20,000 soldiers and horses of the Silla and Goguryeo coalition forces that came to block the attack in the south of Jinma Nagisa Fortress. After half a night of fighting, the coalition army was defeated and fled northward, Liu Ren was willing to take advantage of the victory to capture Jinma Zhu City, and continued to chase more than 40 miles to the north, until the bank of the Xiongchuan River did not stop. In this battle, more than 7,000 Silla and Goguryeo allied troops were killed, and Jinmazhu was captured, so that Anshun, the late king of Goguryeo, who had taken refuge in this country for two years, fled north with hundreds of remnants of defeated troops and followed the defeated army of Silla, and lost more than 50,000 people who fled from the old land of Goguryeo with him in Jinmazhu Castle and became prisoners of the Tang army.

Due to the rapid defeat of the coalition army, An Shun and a group of henchmen fled in a panic, and even the queen did not have time to take it, and was captured by Liu Renyuan's general Li Shouzhen, and lay on Liu Renyuan's bed that night.

……

On the city of Shangzhou, the elderly Jin Yuxin looked at the three trenches dug by the Tang army around the city outside the city with melancholy eyes, how could he not see that the purpose of the Tang army's move was not to break the city at all, but to besiege him.

"Presumably, King Yan's army will attack Jincheng by going south!"

As the status of the Silla kingdom is second only to the king, Kim Yuxin knew that although there were still tens of thousands of horses in Silla at this time, these farmers who had been recruited could not even shoot arrows accurately and could not hold knives steadily.

The Tang Army's road to Jincheng was actually a smooth road in the eyes of Jin Yuxin, just waiting for the news of the fall of Jincheng to come one day.

Kim Wenzhi, the son of Kim Yuxin, was full of bitterness about the imminent defeat of Silla, and prayed again: "Father, instead of sitting here and waiting for death, it is better to gather the whole army and rush out of the city to fight the Tang army to the death." Perhaps the heavens could not bear the destruction of Silla, and our army was fortunate to defeat the Tang army, cut off the retreat of the Tang army going south, and would surely save Silla from falling immediately. ”

"After fighting with the Tang army for more than a month, the 30,000 elite soldiers brought by the old man are now only more than 17,000, and the young and strong people who can be used in the city are only in their early 20,000s, which is almost the same as the strength of the Tang army outside the city, and I want to defeat ......it."

Speaking of this, Jin Yuxin shook his head and sighed, with the current low morale in the city, on the contrary, the morale of the Tang army is booming, plus a few days ago, a Tang army cavalry came to support, and its banner is Qin Jingqian, the left guard of the Beihai Iron Cavalry, at this time, it is not a success to defeat the city.

Infantry against cavalry, once the city is lost and the favorable terrain is relied on, it will inevitably end in a crushing defeat.

Silla was dominated by infantry, and there were very few cavalry, and Kim Yuxin clearly remembered that two years ago, he was defeated by the cavalry led by the Tang general Li Jinxing at the Lulu River, and he was beaten with 20,000 soldiers and only a few hundred remnants fled back.

Jin Yu Nobu sighed, the odds of winning out of the city are too low, Nuo is to continue to hold on to Shangzhou, can still contain a part of the Tang army, help Jincheng reduce the pressure on the Tang army, maybe Jincheng may hold on, if it cannot be attacked for a long time, the Tang army may temporarily withdraw its troops.

Jin Wenzhi's negative attitude towards his father, it was difficult to hide the disappointment on his face, and a wave of anger arose in his heart, he turned back to his residence, and discussed with several generals who advocated going out of the city to fight to the death, and led their subordinates out of the West Gate tonight to attack the Tang army. If he can succeed, he will take advantage of the situation to cover up and sweep the Tang army camp outside the city.

At night, Jin Wenzhi and the others waited for the arrival of Zi Shi with nervous hearts, and none of the 5,000 centaurs to which they belonged fell asleep.

In the south of Shangzhou City, after nightfall, a man in black fell out of the city, and appeared in the big tent of Tang Zhongjun outside the city two quarters of an hour later, handing a letter to Li Shangdan.

Li Shangdan smiled lightly after seeing it, and said to the man in black: "You go back and tell your master that after he assists in capturing Shangzhou, he will be sure to protect his wealth in front of His Royal Highness King Yan." ”

The black-clothed man thanked him and left in a hurry, but the generals in the tent looked at Li Shangdan with a confused expression, and said in his heart, who in Shangzhou City wants to surrender?

Liu Shijiangxun asked, "General, what did you say in the letter?" ”

"The south gate guard general Yi Jin sent a letter expressing his willingness to surrender, and said that tonight, Jin Wenzhi, the son of Jin Yuxin, and four generals in the city led his troops of 5,000 people out of the west gate to attack our army."

"General, will there be a bombing? Our army promised to mobilize elite soldiers to ambush at the West Gate, and it would not be good for the Silla Army to take the opportunity to kill from other gates. ”

Li Shangdan put away his smile and said in a deep voice: "There is such a possibility, but Ximen can't be unguarded." ”

"Shangzhou City is only two miles in radius, our army is surrounded on all sides, and the distance between the two is only two miles. There are 3,000 Yanyun Iron Cavalry Left Guards under the command of General Qin to support, and they are not afraid of the Silla people's deception. Therefore, a certain plan is to divide the Yanyun Iron Cavalry into three groups tonight and place them on the west, south, and east sides of the city, no matter which gate the Silla army rushes out from, the cavalry outside the other two gates can quickly come to support. ”

"I don't know what General Qin thinks about this?"

Qin Jingqian arched her hand and smiled: "The last general has no objection." ”

After all came down, Li Shangdan mobilized 1,000 people each of the White Tiger Guard and the Flying Tiger Army overnight and handed them over to Qin Jingqian to set up an ambush at the West Gate, plus the 5,000 Pingxin Right Army led by Sha Yan formed by the Silla Army outside the West Gate, and a large net was immediately spread out outside the West Gate, waiting for the Silla people to jump in.

In order to prevent the Silla people from bombing, Li Shangdan ordered the defenders outside the other three gates to strengthen their defenses, and the Silla army really fought out from the other gates, and the defenders could first hold the camp and wait for reinforcements if they were defeated.

As soon as the time came, under Qin Jingqian's gaze, the west gate slowly opened, and a group of Silla troops resisting more than 30 feet of long logs and planks quietly poured out, and in front of the trench dug by the Tang army outside the city, the logs were erected on the trench, and then the wooden planks were laid, and a simple bridge was erected.

As for why the trenches were not filled with soil, the Tang army dug three trenches 25 feet wide and 12 feet deep. If it was really to be filled with soil, the Tang army would have been alarmed and gathered outside the trench and shot it with bows and crossbows, and the Silla army would have been killed and wounded before filling the trench and rushing over to tear it up, and then it would have been annihilated by the Tang army.

When the Silla army was building a bridge in front of the second trench, Sha Yu asked, "General Qin, when will our army attack?" ”

Qin Jingqian said expressionlessly: "Don't rush first, wait for them to build the bridge, and then attack after most of them pass through the trench." ”

After the bridge over the third trench was erected, the Silla army, which had been waiting for a long time, lined up on the opposite bank like a slender torrent through three improvised wooden bridges. Although they were the only remaining elite soldiers in Silla, they still looked panicked when they were arrayed, which made Jin Wenzhi and other generals raise their throats, for fear that they would be discovered by the Tang army and take advantage of this chaotic moment to attack.

I was really afraid of something, in the silent night, suddenly the war drums resounded all around, thousands of Tang soldiers roared, shouted and rushed out of the night, rushing to the front of the two thousand spearmen, holding Zhangba spears and pointing directly at the Silla army that was still in formation.

Jin Wenzhi was shocked, there were still three horses that had not yet passed through the trench, the soldiers in the formation were not in order, and the whole team was even more panicked in the face of the sudden killing of the Tang army.

The Tang spearmen had not yet arrived, the arrows of the crossbowmen had arrived in advance, the lighting of the torches was limited, and the sound of the Tang army rushing and killing was so loud that the Silla army did not hear thousands of arrows swishing in an arc through the air towards the Silla army.

The Silla army, which was caught off guard, was instantly shot down by the arrows that spread out, and as many as seven or eight hundred people were knocked down, and the spearmen of the Tang army also rushed at this time.

Jin Wenzhi was ruthless, and he didn't consider the formation anymore, so he drew his sword and ordered the whole army to rush and kill. The scattered Silla army collided with the Tang army spearmen who rushed towards each other, and spear blades stabbed into the chests of the Silla soldiers one after another, reaping the lives of one by one.

The Tang spearmen were followed by the sword players, and many brave Silla soldiers broke through the formation of the spearmen and were slashed by the sword players behind them, and the crossbowmen were still throwing arrows at the Silla army that was passing through the trenches.

On the wooden bridge with three trenches, many Silla troops were still surging forward, but the fierce battle ahead had long blocked the way forward, making them move forward extremely slowly. The arrows of the Tang army continued to shoot down, and a large number of soldiers fell into the trench with arrows, and those who were pierced by the sharp stakes erected in the trench let out a terrible scream.

Some people were squeezing forward, some people wanted to retreat to escape from this failed sneak attack, and they rushed back and forth, causing more soldiers on the wooden bridge to be squeezed off the wooden bridge and fall into a trench more than ten feet deep, and die tragically on the sharp piles.
