The movement of Zhu Zhu's 100,000 army was immediately discovered by Luoyang's intelligence spies, who immediately sent a message to inform the Jin army in Hebei.

Guo Song immediately realized that Zhu Jun was about to withdraw his troops, and they had captured several enemy spies outside the city, and learned from the spies that the other party's food could last for a month.

If the Jin army had not taken Huaizhou and Liyang City, Guo Song might have believed that Zhu Zhu would confront him for a while, but the situation has changed, especially the loss of Liyang, a logistics center, Zhu Zhu will definitely not be able to withstand the huge pressure and will definitely retreat south in advance.

So during this time, the Jin army scouts were paying attention to every move in the city.

A few days ago, on the high ground in the west of Changle County, a tall wooden platform was completed, the wooden platform is as high as five zhang, covering an area of about three acres, and there is a wooden platform on it, which can stand more than a dozen soldiers.

In fact, this is a lookout, about two hundred steps away from the city, from the high platform can clearly see the situation in the county, as long as Zhu Zhu's army has the move of assembling and retreating, the soldiers on the high platform will immediately find out.

Although the high platform is within the range of the crossbow arrows, the thick wooden planks around the high platform form a natural shield, so that the soldiers of the Zhu Jun army can not hurt a single hair of the soldiers, but the wooden platform is full of arrows, there are tens of thousands of them, and under the moonlight, the high platform is like a monster covered with hair.

This night, the moon is dark and the wind is high, the clouds are thick, and it is dark more than a dozen steps away, this is the fifth day after the loss of Liyang, as usual, the soldiers on the high platform are still patrolling back and forth, paying attention to the movements in the city, in fact, the night is too dark, the soldiers on the high platform can't see the situation in the city at all, and even the county town only faintly sees an outline.

However, there are torches on the city wall, and under the light of the fire, you can see a soldier standing on the head of the city with a spear in his hand, and the time gradually reached the third watch, and finally a soldier found out that something was wrong, and two hours have passed, and the soldier standing at the head of the city is still motionless.

"Shoot him!" The brigade commander on the high platform ordered.

Immediately, a soldier raised his crossbow and aimed at the enemy soldier in the firelight, 'Click! With a bang, an arrow was fired, and it hit the enemy soldier in the chest, and the arrow went into the chest, but the soldier remained motionless.

"No, it's a dummy!" Everyone exclaimed together.

The brigade commander immediately sounded the alarm, 'Dang! While! While! ’

A sentry cavalry rushed up and asked in a loud voice, "What happened?" ”

"Hurry up and report to Your Highness, the soldiers standing guard on the city wall are dummies."

The cavalry immediately turned his horse's head and ran towards the camp, at this time Guo Song had already fallen asleep, and his own soldiers woke him up, "Your Highness, there is an abnormality in the city!" ”

Guo Song sat up all of a sudden and asked, "What's the situation?" ”

"The soldiers at the lookout reported that the soldiers standing guard at the head of the city were dummies."

"Not good!"

Guo Song suddenly understood that the enemy army was going to flee tonight, and he thought that Zhu Jun's army would flee a few days later, at least until the reinforcements were deployed!

I didn't expect to escape tonight, which was completely unexpected by Guo Song.

He immediately ordered: "Tell the cavalry to prepare for pursuit!" ”

At this time, Zhao Jun, the general of the pro-soldier Zhonglang, said cautiously: "Your Highness, I'm afraid tonight is not suitable for cavalry combat." ”

Guo Song suddenly thought of something, and walked quickly to the outside of the tent, only to see that it was dark outside the tent, there was no moonlight, no starlight, dark clouds were heavy, and the big tent more than 20 steps away was invisible.

At this time, the cavalry attacked, which was likely to cause the cavalry to collide with each other, and Zhu Zhu would really pick the opportunity.

At this time, a soldier hurriedly ran to report, "Your Highness, the cavalry on the outskirts has found that the enemy army has withdrawn to the south, and the number is extremely large, it should be the main force of the enemy!" ”

Guo Song really felt a little remorseful in his heart, and he was still thinking about directly using a large iron thunderbolt to blow up the city wall, or burning Changle County, forcing the enemy army out of the city, both of which were sure to defeat the enemy army.

But he only hesitated a little, and the opportunity was lost.

"Go and ask Mr. Wang to come and see me immediately!"

Guo Song sent his own soldiers to invite Wang Yu, and he himself paced back and forth in the big tent, Guo Song also realized that he was a little complacent recently, or a little underestimated the enemy, and always thought that Zhu Zhu could not escape his palms, so that he did not even use effective methods such as attacking the city and burning the city, and waited for Zhu Zhu's army to retreat.

But he forgot that although Zhu Zhu was unbearable, he had a master under him, and his military advisor Liu Sigu gave advice and really deceived himself, and it seems that the so-called reinforcements are also a deceptive strategy, which makes him misjudge.

Soon, Wang Yu also hurried over, "Your Highness, Zhu Jun withdrew his troops, why didn't he pursue him?" ”

Guo Song smiled bitterly and said: "Look at this night, you can't see your five fingers, how can you pursue?" ”

"Your Highness, let the cavalry each hold a torch, and then slow down the horse, so that you can reach the north bank of the Yellow River at dawn before the enemy, and then intercept it back, and the Zhu Jun army will not be able to escape."

Guo Song was stunned for a moment, and he couldn't wait to give himself a slap in the face, he thought wrongly, and wanted to fight fiercely with the enemy, but forgot that he could intercept the enemy in front, if it was a night road, just light the torch, and the cavalry could control the war horse according to the distance of the firelight.

Guo Song immediately said to Pei Xin: "General Pei can lead 30,000 cavalry to the south, not to fight the enemy for the time being, to rush to the Yellow River to intercept before the enemy, and ask each cavalry to bring more torches!" ”

Pei Xin had already heard Wang Yu's suggestion, and he was very clear about the lord's intentions to fight, so he immediately bowed down and said, "Obey His Highness's orders!" ”

At this time, 50,000 cavalry had been assembled, Pei Xin left 20,000 cavalry, and he and Yang Xuanying led 30,000 cavalry to the north bank of the Yellow River with torches in hand.

..........

Zhu Jun's retreat this time can be described as careful preparations, they originally planned to retreat last night, but Liu Sigu found that the weather was abnormal, and inferred that it might be cloudy the next day, so that it was dark at night, which was very conducive to the withdrawal of troops.

They postponed the plan by a day, and sure enough, Liu Sigu bet on the weather, the weather was gloomy, black clouds were thick, and they couldn't see their fingers at night.

It was not until an hour before the departure that Zhu Jun summoned the generals to evacuate tonight, according to the previous plan, the 90,000 troops were divided into three routes, and Zhu Zhu led the 40,000 troops to evacuate to the southwest, through the forest to the Yellow River,

The general Niu Zongliang led 30,000 troops to evacuate to the southeast, and ordered the general Wang Yu to lead 20,000 old and weak troops to evacuate from due south, using them to attract the attention of the Jin army.

Liu Sigu wants time, he is not afraid that the Jin army will see through it, he only hopes that when the Jin army sees through it, it will be too late to intercept the main force.

Zhu Zhu's main force had 10,000 cavalry, plus 30,000 infantry, and when they came out of the south gate, they turned around and ran in the southwest direction.

At the fourth watch, the army entered the forest, here is not a primeval forest, but a three-hundred-year-old sub-forest, the forest is luxuriant, there are many small rivers, there is an official road in the forest, the whole forest is about 40 miles wide from north to south, running out of the forest, it is less than ten miles away from the north bank of the Yellow River.

So the moment he entered the forest, Zhu Zhu breathed a long sigh of relief, and their army already had ninety percent hope of returning south.

Hebei is Guo Song's home field, he fought a decisive battle with Guo Song in Hebei, and there were few victories, but if he fought with the Jin army in the Central Plains, the victory or defeat could be five or five points, so although the number of Zhu Zhu's army was on par with the Jin army, he still did not have the courage to fight a decisive battle with the Jin army.

The 20,000 troops evacuated in the south direction are also running southward, they are afraid of being chased and killed by the Jin army, so they did not light the torches, but ran in the night, they rushed along the west bank of the Lu River, they ran out of about 20 miles, and suddenly found that there was a cavalry brigade on the other side of the river running south, the cavalry held torches, two people in a row, the speed of running was not fast, there was no end in sight in the night, like a fire dragon drifting in the air.

The hearts of the 20,000 soldiers of the Zhu Jun Army became heavy, and they actually encountered the Jin army, but the strange thing is that the riverbed was frozen, but the other party did not kill it, which made them feel a little relieved, maybe the other party's target was not them.

In a short time, the cavalry faded away, and the last point of fire was gone, and the soldiers breathed a long sigh of relief.

As the day drew bright, the 20,000-strong army arrived at Guanshui Town, which was still thirty miles from the north bank of the Yellow River.

The town is very small, in fact, there is only one street, and the people in the town have fled to the Jin Kingdom, and the town is basically an empty town.

At that moment, a low horn sounded ahead, 'Woo-'.

The soldiers were stunned and stood up one after another, and then there was the sound of trumpets from the east and west, and three black-pressed cavalry appeared, surrounding them from three directions.

They had no other way but to flee back.

But soon, the soldiers found that the road to the north was also blocked, and a stronger army appeared in the north.
