Soon after Fanning arrived in Beidao, the Song Dynasty received secret information from Yelu Yixin, and the five princes of the Liao royal family took advantage of Yelu Hongji to lead the army to Tokyo Province, and launched a palace coup d'état in Shangjing, and established Yelu Angkor, the grandson of the King of Chu, as the new emperor, Yelu Hongji led 100,000 troops to rush back to Shangjing in a panic, and the current defenders of Tokyo Province are only 50,000 people.

At the same time, the Intelligence Department also received a spy report from Tokyo Province, and Yelu Hongji led a large army to retreat north in panic.

The Son of Heaven Zhao Ji realized that this was a once-in-a-lifetime opportunity to attack Liaoyang Mansion in Tokyo, and immediately issued an order to make Han Jiang end his preparations for the battle in advance and launch an attack on Liaoyang Mansion.

At this time, the Great Song Dynasty had gathered 500,000 troops and 2,000 warships on the front line of Pingzhou, with Prime Minister Han Jiang as the main commander, Han Jiang immediately ordered the general Cao Shi to be the vanguard, leading 100,000 troops to Jinzhou, and ordered the naval army to control Miao Shunli to lead 1,000 warships along the Liao River north, with Cao Shi's 100,000 army, must seize Liaoyang Mansion in a battle.

In the afternoon of that day, Cao Shi's 100,000-strong army passed through Jinzhou, and they marched lightly, bringing only ten days' dry rations, while their various baggage supplies were sent by waterway warships.

Jinzhou currently has 8,000 Song troops stationed, the main general is called Liu Zhen, is a commander, when Cao Shi's army went north, Liu Zhen suddenly breathed a long sigh of relief, at least he now does not have to worry about the Liao army attacking Jinzhou.

Not only the main general Liu Zhen was lax, but the defenders in the entire city were also lax, and the Song army had tightened the strings in the past few months, and they did not dare to relax for a moment, and the soldiers were really tired.

At this time, the crossing of the army made Jinzhou from the front line to the rear all of a sudden, and the soldiers also deserted, and the generals no longer urged and let the soldiers rest.

At night, Liu Zhen found two prostitutes to drink with him, and more than a dozen of his generals also got together to drink.

The soldiers also went to bed early, and there were only more than 1,000 people on duty at the head of the city, and the general on duty was called Li Song, who was born in the box army, and was quite excluded in the Jinzhou garrison, which was dominated by the forbidden army, so everyone else was resting and drinking tonight, but he was arranged to be a guard on duty.

Li Song also knew that he was not popular, he was very depressed, but he was also quite dissatisfied with the indulgence of the main general Liu Zhen, although the main force had already crossed the border, and he could relax a little, but after all, it was a time of war, and the military order was very clear that alcohol was not allowed during wartime, which was a serious violation of military regulations.

It's just that others are soft-spoken, and if they speak rashly, they may encounter misfortune, at this time, the best way is to be silent, as if they didn't see anything.

Just when the Song army thought that the main force had crossed the border and Jinzhou had become the rear, a Liao army of more than 15,000 people quietly approached Jinzhou.

This Liao army did not come from eastern Liao, but from the Dading Mansion in Zhongjing to the west.

It is no wonder that although Dading Mansion is named Zhongjing, it has been existing in a chicken rib way for a long time, and its economic importance is far less than that of Liaoyang Mansion in Tokyo, its strategic importance is not as good as that of Yanshan Mansion in Nanjing, and its importance in external relations is not as good as that of Datong Mansion in Xijing, let alone compared with the real capital city of Shangjing.

It's just that the Liao State needs a Zhongjing, and Dading Mansion can be named.

Dadingfu not only looked down on it by the Song army, but also did not attach importance to it by the Liao State itself, with a garrison of less than 20,000, and it was not an elite army, but only a Khitan reserve army, which was equivalent to the militia of the Great Song Dynasty.

Because of this, the Song army guarding Jinzhou never took Dadingfu to heart, although the importance of Jinzhou is to guard the intersection of Tokyo Road and Zhongjing Road, but the Song army still set their sights on Liaodong and never wasted a little thought and energy on Dadingfu.

The Liao army of 15,000 people approached the north gate of Jinzhou, and was ambushed three hundred steps away from the city.

A group of more than 1,000 Liao soldiers had quietly approached the northern city of Jinzhou, they were wearing the armor of the Song army, but each of them had a white belt tied to their left arm.

When the Song army had just occupied Jinzhou City, there were still 1,000 Liao army ambushes in Jinzhou City, ready to join forces with the Liao army outside the city.

Later, the Song army did not find this secret passage, the north gate of Jinzhou is the urn city, generally the urn city has a secret passage from the city head to the urn city, this secret passage is built in the city wall, you can go directly down from the north city head to the urn city.

The Liao army did something on this secret passage into the urn city, and opened five feet to the outside of the city to the north, don't underestimate these five feet, so that the secret passage and the outside of the city are only separated by a city brick, and the city bricks have been loosened.

This secret passage opened outward had been well covered, and the Song army did not find it, and the Song army did not use the urn city.

Thousands of Liao soldiers rushed against the city walls, there was no moat in Jinzhou, and the Song army dug a trench outside, but for the Liao army with long planks, this trench was meaningless.

A thousand Liao troops rushed to the north city gate, two extremely strong soldiers with an iron crowbar brick by brick experiment, they soon found the loose wall bricks, with a crowbar slowly pulled out the wall bricks, pulled out five city bricks, there was a big black hole in front of the eyes, this is a narrow passage, the length and width are three feet, inside five feet is a camouflaged thin wall, remove this thin wall, behind is the city head of the narrow road leading to the urn city.

Two soldiers climbed in, brick by brick, and passed outward, with great care, lest the thin wall collapse and alarm the soldiers at the head of the city.

After a while, a pitch-black passage appeared in front of the Liao army, which led directly to the head of the city, about eight feet high, but only two feet wide, very narrow.

Two strong Liao soldiers were the first to enter the Yongdao, and the soldiers behind followed one by one, and the Yongdao was located on the left side of the city tower at the opening of the city head, and was covered with a heavy wooden plank, and the wooden board had an iron ring, and when the wooden board was opened, you could go down the steps.

The plank opened a crack, the city was very quiet, most of the soldiers on duty at night were sleeping on the city wall, the plank was slowly lifted, two strong Liao soldiers jumped out, and the Liao soldiers poured out one after another, they divided into two ways, one way to the sleeping Song soldiers, and the other did not hesitate to run to the winch that opened the city gate.

.........

Li Song, the main general on duty, happened to be in Nancheng at this time, because it was possible that the main force of the Song army would come from the south at night, so the defenders must ensure that the defenders could open the city gate at any time.

Suddenly, there was a shout of killing from the head of the north city, Li Song was startled, turned his head to look at the north city gate, and saw a fire on the head of the north city.

He was immediately taken aback, most of this kind of fire was a signal to notify the ambush outside the city, and he immediately shouted with his horse's head: "Follow me!" ”

He ran along the city with three hundred soldiers to the north.

When he was still two hundred steps away from the head of the north city, he grabbed the reins, only to see the north gate wide open, and the black and oppressive army was surging in from the outside, and the urn city gate was also opened, and countless enemy troops were rushing towards the city gate.

At this time, a group of soldiers fled from Beichengtou in panic, Li Song was shocked and anxious, stopped the group of soldiers with a wave of his gun, and asked sharply: "What happened in Beicheng?" ”

A soldier said with a crying voice: "The Liao army came out of the urn city and killed thousands of people, and the brothers could not resist it, and the city gate was lost. ”

Li Song was suddenly anxious, he immediately sent soldiers to inform the military camp and the main general Liu Zhen, and he himself turned his horse's head and ran to the south city, at this time it was no longer meaningful to go to the north city, next to the south city was the warehouse, there were five hundred iron fire thunders in it, he knew the importance of iron fire thunder, he must ensure that these iron fire mines could not fall into the hands of the Liao army.

At this time, the 15,000 Liao army has been killed out of the city of Jinzhou, the city of Jinzhou is full of fire, the main general Liu Zhen is drunk and not awake, the 7,000 soldiers in the barracks are in a panic, most of them are not wearing armor, many people are still barefoot, only a knife, was killed by the Liao soldiers and retreated, the casualties were extremely heavy, the soldiers of the Song army soon could not support, completely defeated, and began to rush to the south gate.

As soon as Li Song opened the door of the warehouse, he received a report from the soldiers, "General, the main force of the military camp has been defeated and is fleeing towards the south gate." ”

"What about Liu Tong?" Li Song asked anxiously.

A fire has been ignited in the commanding army, and the life and death of the commandery are unknown.

Li Song suddenly realized that the general trend had gone, and the iron fire and thunder could not be transported, so he immediately ordered: "Pile up the forage in the firearms warehouse and light the fire!" ”

The soldiers piled hundreds of loads of hay into the firearms storehouse and threw dozens of torches, and the firearms storehouse suddenly ignited a raging fire, while Li Song took three hundred soldiers to the west gate, which has always been unpopular, blocked by mountains to the south, and could not retreat south, but there was a small road to retreat to the north.

In the dark night, a series of earth-shattering explosions suddenly broke out in Jinzhou City, the whole city was shaking, and the earth was trembling.
