Early the next morning, the army continued to march, backward march, the Song army no longer encountered a small group of gold soldiers harassment, seven days later, the 100,000 army arrived at a grassland about eighty miles away from Datong City, this grassland is dozens of miles wide, Datong water flows slowly from the grassland, Liu Jian immediately ordered to set up a large camp here.

The 20,000 Song troops soon cut down a forest ten miles away, and a large amount of wood was used as a barracks, and soon a fence-type military camp covering an area of about 1,000 acres was set up, and a guard tower was built every fifty steps.

The reason why Liu Jian began to build a military camp eighty miles away was that it was an effective strategy to deal with the Jurchen cavalry, called the battalion step by step, and the military camp was constantly moving, so that the Jurchen cavalry would always face the military camp of the Song army.

At the third watch, the 100,000-strong army set out again, marching thirty miles, and set up camp in the wilderness about fifty miles away from Datong City.

At the third watch of the next day, the 100,000 army set off again, and at the fourth watch, the large camp was set up again, this time the Song army only walked ten miles, and camped about forty miles away from Datong City.

Liu Tie hurriedly came to his brother's tent early in the morning, he clasped his fists and saluted, "See Dutong for your humble position!" ”

Liu Jian smiled and beckoned to his brother, "Come here, I have a task for you." ”

Liu Tie stepped forward, "Brother Fei thinks Jin Bing will come today?" ”

Liu Jian said with a smile: "I hope they don't come, let me fight a siege battle, another street battle, and annihilate the 20,000 cavalry, but I estimate that they will come today." ”

"What mission did my brother give me?"

"I'll give you 10,000 cavalry, you lead the army to the north of Datong City, once the main force of the Jin soldiers goes out of the city to attack the Song army camp, you will directly attack the city for me."

"Brother, did you ask me to blast open the city gate with earth-shattering thunder?"

Liu Jian nodded, "The spies have already explored clearly, the north gate of Datong Mansion is an old wooden gate, and there is not even a suspension bridge, I will give you this meritorious opportunity, whether you can be reinstated depends on your performance." ”

"Obey!"

Liu Tie was overjoyed that he finally had the opportunity to make meritorious service and atone for his sins.

After leading 10,000 cavalry to the south for thirty miles, he turned around and headed north, running towards the north of Datong City, so that although he made a big circle, he could effectively avoid the Jin soldiers and spies and go around to the north of Datong City unconsciously.

..........

Wanyan Chathorn is a veteran of more than forty years old, is the younger brother of Wanyan Aguta, the Taizu of the Jin State, and also made great achievements in the battle to destroy Liao, and once served as the commander of the Southern Army, but in the internal power struggle of the Jin State, he was hated by Wu Qimai because of his resolute opposition to Wu Qimai's accession to the throne, and was gradually marginalized, and was appointed as the capital of Xijing Road of the Jin State, sitting in Datong Mansion.

It sounds good, for one side of the princes, but in fact he is far away from the political center, and also away from the Song Dynasty and Mobei, the two hot spots of the war, so that there is no opportunity to make meritorious contributions.

Of course, Wanyan Cha Thorn also knew the news of the Northern Expedition of the 100,000 Song Army to Datong Mansion, his spies have been staring at this army going north, he originally wanted to use the sneak attack on logistics grain and grass to force the Song Army to withdraw, but he did not expect that the powerful general Pu Cha Yasu he sent finally failed, and more than 1,000 people were annihilated, which really disappointed him.

Wanyan Cha Thorn stood at the head of the city and looked south, he had just received the news that the Song army had marched ten miles north again last night and set up a large camp, only forty miles away from Datong City.

Wanyan Cha is really embarrassed, whether he sends troops or not, it has no effect if there are fewer troops, there are more troops, and he is afraid that the city will be lost, he only has 19,000 troops now, and it is difficult to dispatch troops, but the other party is 100,000 troops!

But if you don't send troops, once the other party comes to the city, they will start to fight siege battles with themselves, so what's the point of your own cavalry?

The adjutant general Duo Lira suggested: "The enemy army obviously will not stop at thirty miles away, and will definitely come to the city, and the other side will set off at night at three watches, why don't we launch an attack at this time and take the enemy army by surprise." ”

After thinking about it for a whole day, Wanyan Chathorn finally decided to send troops to attack the Song army's camp, and if the attack was unfavorable, he would immediately withdraw his troops back.

In the night, he left the general to take away the army of 2,000 to defend Datong City, and he led 17,000 cavalry to gallop out of the city and kill the Song army camp forty miles away.

Just as the Jin soldiers rushed out of Datong City, they were immediately discovered by the Song army scouts, and their soldiers divided into two routes, one rushed back to the camp to report to the main general, and the other rushed to the north to report urgently to Liu Tie, who was ambushed north of Datong City.

The speed of the golden soldiers was extremely fast, and when there were still twenty miles away from the Song army camp, they were discovered by the sentry on the sentry tower, and in the clear night sky, a large number of dark clouds suddenly rose, completely obscuring the night sky in the north, and the earth was rumbling and echoing, and the sentry immediately judged that this was either a sandstorm coming, or the golden soldiers were killed.

'When! While! While! ’

The alarm bell rang urgently, and the Song army, which had already been ready, began to run in formation, each rushing to their combat position, among which 30,000 crossbowmen were deployed in front of the camp fence, ready to meet the attack of the Jin soldiers on the large camp.

Liu Jian has a lot of combat experience, he knows that thirty miles is an important psychological defense line for the cavalry, once it breaks through the thirty miles, it will seriously affect the psychological advantage of the cavalry, so he judged that Yan Cha Thorn will no longer tolerate himself to continue to approach the city wall, if he does not have the determination to defend the city without fighting, then he will definitely come to the surprise attack tonight when the Song army moves.

The third watch has passed, and Liu Jian is still standing still, waiting for the killing of the Jin soldiers.

At this time, the earth is trembling, the Song army has put away the big tent and lined up to stand in the wilderness of the camp, the tall camp fence has become the protective wall of the Song army, 30,000 crossbow arrows are waiting for the crossbow with the divine arm, of which 9,000 crossbow troops are deployed in the north, and 7,000 people are deployed on each of the remaining three sides, and the soldiers on the guard tower have all withdrawn, everything is ready, and there is silence in the camp, waiting for the arrival of the big war.

When the 17,000 cavalry was still three miles away from the northern military camp, two branches were suddenly divided, each with 3,000 cavalry to attack the east and west camps of the Song army, and the remaining 10,000 cavalry were still staring at the northern military camp, but their speed slowed down significantly, and finally stopped about 200 steps away from the main camp, and the first 2,000 cavalry accelerated to the gate of the barracks, and they would directly rush open the gate and kill into the camp.

Liu Jian secretly scolded, this Wanyan Cha was not stupid, knowing that he was prepared, he only sent two thousand people to test the attack.

He had to yell, "Get ready to shoot!" ”

Nine thousand divine arms and crossbows were raised, aiming at the two thousand cavalry who were getting closer and closer, although there were only two thousand cavalry, but the momentum was fierce, and there was still the momentum of ten thousand horses galloping.

"Shoot!"

When the enemy army entered one hundred and fifty steps, Liu Jian gave the order to shoot, the sound of bangzi sounded, first the first row of three thousand arrows shot, shot at the overwhelming cavalry, arrows like rain, led by hundreds of people have been hit by arrows and fell off their horses, but the cavalry behind is still galloping rapidly, not affected by the fallen soldiers at all, the war has reached this point, they have no other way out except to fight to the death.

After the first row of 3,000 people finished shooting, they immediately retreated and loaded their arrows, the second row of 3,000 crossbow troops stepped forward to fire, and 3,000 arrows were densely shot at the enemy, followed by the third row of 3,000 crossbow troops stepped forward to shoot, and the three rows of 9,000 soldiers rotated like marquees, like a storm of arrows shot at the 2,000 cavalry again and again.

After only two rounds of six shots, the two thousand cavalry finally completely disintegrated, stopping at sixty paces, and the remaining hundreds of cavalry turned around and fled in panic.

At this time, the Jin soldiers on the east and west sides were also beaten by the strong bows and crossbows of the Song army, leaving more than a thousand corpses and fleeing back in embarrassment.

The main force of the Jin soldiers also quickly retreated, but they did not go far, but stared at the Song army camp three hundred paces away, looking for loopholes in the Song army's camp, like unwilling wolves, always patrolling around their prey.

Wanyan Cha Thorn is indeed unwilling, his current strength has dropped from 17,000 to 14,000, but he hasn't even caught the hair of the Song army, how can he retreat easily?

At this time, the barracks fence on the north side suddenly fell forward, a width of a hundred zhang wide, revealing the dark inside of the barracks, and the crossbowmen of the Song army lined up behind the fence seemed to be caught off guard and retreated one after another.

The sudden flaw was exposed in front of Wan Yan Cha Ting, which made him excited and confused, he suspected that there was a hook hidden in it, but if he looked closely, it was not like Song Jun deliberately pulled down, but like the soil was loose and fell, making people suspect that it was the result of Song Jun hastily setting up camp, Wan Yan Cha Thorn's heart jumped wildly, this huge temptation he really couldn't resist.

He turned around and shouted, "The fifth, sixth, and seventh battalions will kill me!" ”

"Woo————"

The low horn sounded, and the three thousand cavalry suddenly launched, with iron hooves galloping, rushing towards the Song army camp like a flash flood, and they were still greeted by dense arrows like a storm, and the Jurchen cavalry continued to scream and fall, but gradually approached the Song army camp.

Liu Jian sneered, "Light a fire for me!" ”

At this time, countless rockets took off into the air and shot at the dense enemy army, but their target was not the enemy, but the ground, the fire oil on the ground was suddenly ignited, quickly burned, spread extremely fast, the war horses neighed, frightened, and the Song soldiers stopped shooting and lay on the ground one after another.

Wanyan Cha suddenly reacted, the Song army deployed a trap in front of the camp fence, he was tricked, and he hurriedly ordered: "Quickly Mingjin retreats!" ”

But it was too late, dozens of earth-shattering thunderbolts buried in the ground exploded continuously, the explosion sound was thrilling, the rocks pierced through the air, the flesh and blood flew sideways, and the thick smoke filled the earth.

When the smoke cleared, the ground was full of corpses of people and horses, and the horses whose legs had been blown off tried to get up desperately, and the soldiers who were not dead were lying in a pool of blood and groaning, as if they were in hell.

More than 2,000 of the 3,000 cavalry were shot dead and killed, and only the 700-odd people behind escaped by chance, and they all turned their horses and fled, and the wilderness was full of frightened war horses.

Liu Jian suddenly realized the fighter, and he immediately ordered: "20,000 cavalry attack!" ”

The camp gate opened, and 20,000 cavalry rushed out, and under the personal leadership of Liu Kuang, they slaughtered out of the camp and pursued the fleeing enemy army.

.........

At the same time that the enemy began to attack the Song army's camp, the 10,000 cavalry led by Liu Tie also quietly appeared a mile north of Datong City, and there was only an empty military camp outside the north city, and the remaining 2,000 gold soldiers had all withdrawn into the city.

At this time, the three soldiers approached the direction of the city gate with a huge explosion-like earth-shattering thunder, and they moved quickly, sometimes prostrate, sometimes bent and ran, and gradually approached the city gate.

The defenders at the head of the city were very vigilant, but most of the soldiers were deployed in the southern city, and there were only two hundred soldiers in the northern city, and in addition to the soldiers standing guard, there were two patrols patrolling back and forth at the head of the city.

At this time, the three soldiers were only twenty paces away from the city gate, and they were just about to get up and run towards the city gate, when they were suddenly discovered by the sentry at the head of the city, and the sentry immediately shouted, and the soldiers at the head of the city rushed to this side.

Three Song soldiers saw that the situation was critical, immediately threw the fire fold, lit the fire rope, a soldier held the earth-shaking thunder and rushed to the city gate, the city head soldiers have released arrows, the soldier was hit by five or six arrows, one fell to the ground, at this time the earth-shaking thunder rope has burned into the thunder body, but it is still ten steps away from the city gate, another Song soldier rushed up, picked up the earth-shaking thunder and threw it to the city gate.

At the moment when the earth-shaking thunder hit the city gate, a dazzling red light burst out, and the earth-shaking thunder exploded violently, and the Song soldier was caught off the ground, and was swept away dozens of steps away by the powerful shock wave, and died tragically on the spot, while the third Song soldier was also shattered and died twenty steps away from the city gate.

The three Song soldiers all paid the price of their lives, but the north gate of Datong City was blown to pieces, and the gate as high as two zhang was blown up to the edge of only a circle of several feet wide, and a large hole appeared in the middle, which was one and a half feet high and one zhang wide, revealing the black inside of the city.

Liu Tie shouted, "Go into the city!" ”

10,000 cavalry horses galloped and killed in Datong City........
