The one who attacked the capital of Jijing was naturally the Dai army.

As early as more than ten days ago, Sima Shang led the 30,000 raiding Dai army to make a big circle in the north, reaching the valley in the northeast and north of Jijing and hiding, while the main energy of the Qin army was in the west area of Jijing at the junction of Daiyan, so he did not notice that the Dai army had lurked on the edge of Jijing City.

And after lurking in the valley, Sima Shang immediately sent people to contact the Daijun Jinyi guards who had already infiltrated Jijing, and learned about the situation in Jijing City, and now there are nearly 1,000 people in the Daijun Jinyi Guards who have infiltrated Jijing, a total of six batches, ranging from 150 to 200 people in each batch. The armor was brought into Jijing and hidden, so it can be said that it is fully prepared and just waiting for action.

However, at this time, the Qin army had just occupied Jijing, and there were nearly 100,000 garrisons inside and outside the city, and they were very well guarded, so Sima Shang did not dare to act rashly, so he lurked in the valley and waited for the opportunity.

Sure enough, a few days later, the Qin army sent troops to attack the Dai army in ambush on the border of Daiyan, and the Qin army stationed in Jijing City had only more than 30,000 people left, and half of them were stationed outside the city.

Of course, Sima Shang knew that the time had come, so he immediately contacted the Daijun Jinyi guards who infiltrated Jijing, and agreed on the time of the assault, the signal, and the way to cooperate with each other inside and outside the city.

This time, the Dai army assaulted Jijing, and a total of six armies were dispatched, namely the Fan Yong Right Army, the Wei Cavalry Army, the Xiaowu Army, the Pingyuan Army, the Guangde Army, and the Weibian Army, which were two full cavalry armies and four infantry mixed armies, totaling about 30,000 troops.

Because the Qin army still had 15,000 troops stationed outside Jijing City, stationed at the north and south gates respectively, the Dai army placed the goal of assaulting Jijing at the east gate, and it was the Pingyun Army and the Guangde Army that paid the responsibility for the assault on Jijing, and the Fan Yong Army was the reserve for the response; The six groups of people lurking in the city set fire to the four gates of the city, and each of the three gates in the south and northwest sent a group, each batch of about 150 people, the purpose was only to create ** and disturb the attention of the Qin army, and two groups of people were sent at the east gate, the number of about 350 people, this is the real response to the army into the city, and the remaining group of about 200 people was responsible for the preparation of the various roads.

The Weibian Army and the Xiaowu Army were ambushed near the two military camps of the Qin Army stationed outside the city, because once the city was in chaos, the Qin Army would definitely transfer the army outside the city to the city to rescue, so the task of these two armies was to wait for the Qin Army to come out of the camp, and immediately use infantry to attack the Qin Army's camp, and the camp was attacked, the Qin Army would definitely return to rescue the camp, and the cavalry of the Dai Army would take advantage of the situation to kill and attack the cavalry, so that the Qin Army stationed outside the city could be defeated in one fell swoop, and the other all-cavalry Wei Cavalry Army would be responsible for receiving the two Dai troops outside the city.

This plan was also carefully planned by Sima Shang, which can be regarded as very thoughtful and comprehensive.

So after entering the watch, the army immediately came out of the valley, although the valley is more than 50 miles away from Jijing, but the soldiers of the army are equipped with war horses, and although it is dark, but along the road there are Jinyi guards to respond, pointing out the way for the army, so the action of the army is very fast, just after the second watch, it has reached less than ten miles from Jijing.

Under the guidance of the Jinyi guards, all the Dai armies entered their respective battlefield positions, while Sima Shang led the Fan Yong Army, the Pingyuan Army, and the Guangde Army to rush directly to the east gate of Jijing.

At this time, it was close to the third watch, and a waning moon had appeared in the sky, decorated with faint starlight, so it was vaguely visible that the distance of dozens of steps could be seen. And as the distance closes, the soldiers of the Dai Army can also see the light of the fire on the distant city wall.

The Dai army of the assault Jijing met with the Jinyi guards on the side of a small hill about two miles away from the city, at this time they had already made preparations outside the city, and piled up three firewood and grass piles on the top of the mountain, seeing that Sima Shang led the Dai army to arrive, they immediately lit three firewood and grass piles in turn, and the orange-red flames suddenly lit up the sky, which could be seen very obviously from several miles away.

At this time, in Jijing City, the lurking Jinyi guards were also in place, and got weapons and armor, because they were fully prepared in advance, as early as a few months ago, Jinyi Guards bought a house near the four city gates, and the weapons and armor were buried in the underground of the mansion, and at the same time, a large number of hay, dry firewood and other fire-starting things were prepared in the house, so the personnel of the Jinyi Guard hid in the mansion scattered during the day, took out weapons and armor, and waited for the signal of action in the house.

Just wait for the signal to set fire to the house first, create chaos, and then kill it from the house, or expand the chaos, or take the army into the city, so that it is safe, secretive, and convenient.

Just when everyone was waiting a little impatiently, the signal finally came, and after seeing the fire outside the city, the personnel of the Jinyi Guard immediately took action, first setting fire to the house, because at this time, the rooms in the house were full of hay and dry firewood, naturally it was one point, and after a while, the whole house was on fire, and half of the sky was red at once.

And the other Jinyi guards came out of the house one after another, each holding guns and swords, and many people held torches, setting fire around to create chaos, although there were 15,000 Qin troops stationed in Jijing City, but Jijing was the capital of Yan State, although it was not as large as Linzi, Daliang, and Xianyang, but it was not small, and only 15,000 Qin troops were of course impossible to guard tightly in Jijing City, so it also gave Jinwei a lot of time to create chaos. As a result, after a while, there was a fire near the four gates of the southeast, northwest and northwest gates in Jijing City, and there was chaos.

However, although the Qin army's strength is not much, it has left a lot of troops to garrison at the four city gates, and the places where the army creates chaos are also relatively close to the city gates, so the Qin army defending the city saw that the fire in the city was raging and there was a big chaos, so they naturally rushed to fight the fire and pacify the chaos.

In fact, the location of the fire was chosen near the city wall, and it was also carefully selected, in order to attract the attention of the Qin army defending the city, the Jinyi guards of the three gates of the south and northwest took advantage of the chaos to fight with the Qin army who rushed to fight the fire, and dragged the Qin army, and at the east gate, after the Jinyi guard set fire to make **, only a small number of personnel were left to contain the Qin army who rushed to fight the fire, while the others rushed to the direction of the city gate through other streets, of course, this is also the route that has already been set.

Because most of the Qin troops guarding the city gate rushed to fight the fire, the Qin army that stayed at the city gate was very few, only more than three or four hundred people, although the number was not small, but it was necessary to guard the city gate, the city tower, the city wall, etc., and at this time, the army outside the city had come to the Fangcheng River, making a lot of noise, shouting and killing, which also attracted the attention of the Qin army guarding the city wall, so at this time, there were only more than 100 Qin soldiers stationed under the city, and there were only more than 100 Qin soldiers left to defend the city gate, and there were nearly 300 Jinyi guards who killed them, plus the Qin army was not prepared at all, As a result, he was killed and scattered by the brocade guards.

And when the Qin soldiers on the city wall and the city tower found that the situation under the city was not right, they rushed down the city to support, it was too late, and the Jinyi guard killed the Qin army guarding the city gate, controlled the city gate, and then immediately divided into two groups, a group of Qin troops who resisted reinforcements, and a group of people hurriedly went over to open and close the lock, open the city gate, and let the army outside the city enter the city.

But at this time, although the city gate was opened, but the drawbridge was not put down, but the army raided, although it did not bring large siege equipment, but when it was lurking, it still made a batch of long ladders in the valley, which was also just used at this time, and immediately put the long ladder on the moat, as a bridge, and the infantry dismounted one after another, crossed the moat through the long ladder, and then through the open city gate, and entered the city of Jijing.

Although there were not many soldiers who crossed the moat and entered the city of Jijing at this time, it was a great encouragement to the Jinyi guards who fought in the city and stuck to the city gate, and the enemy troops outside the city entered the city, which was a heavy blow to the psychology of the defenders in the city.

And more and more generations of troops entered the city, and separately killed on the city wall, the Qin army was in a hurry to respond to the battle, and in the dark night, the Qin army did not know how many people in the army of the city had to attack Jijing, so their hearts were weak, and their morale was naturally extremely low; And the Dai army has long been prepared, from the Dai County troops, just to assault Jijing, in addition to the Dai army in the valley also held back for several days, has long been full of energy, at this time is even more unstoppable, very brave, although it is the following attack, but still beat the Qin army to defeat and retreat, step by step on the city wall, and then occupy the city tower, and put down the drawbridge.

The fall of the drawbridge also announced the success of the army's assault on the city gate, because the drawbridge is not comparable to a temporary bridge made of long ladders, flat and wide, not only able to pass a large number of troops, but also through the cavalry, so the army in Jijing City has increased several times, and a large number of cavalry have entered Jijing City.

Although the urban war was not a suitable battlefield for the cavalry, the cavalry entered the city and completely knocked out the Qin army's most reluctant trace of resistance. Therefore, the Qin army did not have the heart to fight again, and the Qin army under the city retreated to the city, and the defenders on the city wall also fled along the city wall, and the Dai army finally completely captured the east gate of Jijing.

Sima Shang also breathed a sigh of relief, and immediately urged the horse to pass through the suspension bridge and enter the city of Jijing. In fact, the battle to capture the city gate did not last long, less than twenty minutes in total, but Sima Shang's feeling was that the seconds were like years, because the capture of the city gate was the first step in the raid on Jijing, and it was also the most important step.

Fortunately, the Dai army did not consume much time, and conquered the city gate, which also made a good start for the raid on Jijing, so Sima Shang entered Jijing City, and immediately assigned men and horses to develop in depth in Jijing City, completely defeated the Qin army, and occupied Jijing City.
