After a day's journey, at dusk, Ren's army came to the Yellow River.

Ren Chunli and Ren Decong decided to cross the Yellow River first, then camp on the east bank of the Yellow River to rest, and then continue their journey tomorrow. So the men and horses got on boats and crossed the river. Ren Chunli and Ren Decong also took advantage of such a moment of leisure work, dismounted and found a big rock, and sat down to rest.

The soldiers of Ren's army also walked for a day, and they had already been tired and tired. The number of boats at the crossing was limited, and only more than 2,000 soldiers could be crossed at a time, so most of the soldiers rested in place, and the banks of the Yellow River were immediately filled with men and horses or sitting down. The soldiers who crossed the river began to set up camp, bury pots and prepare for the night.

Although there are a lot of people and horses in Ren's army, but fortunately, the Yellow River here is not wide, it only took more than an hour, and more than 20,000 soldiers have crossed, and at this time the sky is completely dark, and the soldiers on both sides of the Yellow River have lit countless torches, dotted with stars, and illuminated both sides of the river. Ren Chunli and Ren Decong also arrived at the opposite shore by boat.

At this time, dozens of tents were set up on the east bank of the Yellow River, and the first batch of rice was also cooked with scriptures. The two rested and ate in a tent that had been built with scriptures. The other soldiers who crossed the river also sat around the fire to eat. Some of the soldiers who had finished their meals early hid in their tents to sleep, and only boats were still passing on the river.

Just when Ren's army was completely relaxed, on the east bank of the Yellow River, there was a sudden sound of rapid and dense horses' hooves, from far to near, and in an instant, it was close to the front. In the darkness, countless cavalry troops suddenly struck out, charging towards the unprepared Ren army. But the sharp-eyed soldiers saw clearly the armor of this cavalry army, which was the Song army.

In fact, Song Junhe deliberately gave up Anxi Mansion, the purpose was to lure Ren's men and horses out of Pingxi Mansion. Because Anxi Mansion has been governed by the Great Song Dynasty for more than a year, it has initially stabilized the hearts of the people, even if it is temporarily occupied by the Ren army, it is not difficult to take it back. Pingxi Mansion is a place where the Ren clan has been operating for decades, and once the Ren clan is stubbornly defending the city, the Song army will be difficult to capture in the short term in the absence of large-scale siege equipment.

Therefore, Bi Zaiyu set up this bold and risky plan, and when Ren's army attacked first, the Song army took the initiative to abandon Anxi Mansion. As a result, all the main forces of Ren's army were attracted to Anxi Mansion. Then take advantage of the weakness to take Pingxi Mansion first, and after Ren's army learns that Pingxi Mansion is attacked, it will definitely mobilize a large army from Anxi Mansion to help, and then set up an ambush by the Yellow River, and take advantage of Ren's army to attack half-crossing, it is very easy to defeat the main force of Ren's army, and then recapture Anxi Mansion, then the entire Ren rebellion can be decided in one fell swoop.

However, this plan is also very risky, because Anxi Mansion is different from other places, and its political significance and symbolic significance are still very huge, once Anxi Mansion is lost, it is easy to give the party nobles the feeling that the Song army cannot control the situation, and if it is not done well, it will cause the Anxi region to be completely out of control. Therefore, Bi Zaiyu and Xin Qiji repeatedly discussed, and decided that if Ren's army did not send additional troops to Anxi Mansion within three days, the Song army would no longer wait, and immediately send troops to recover Anxi Mansion, and then immediately join the imperial garrisons of Yinzhou and Xiazhou to storm Pingxi Mansion.

After discussing and deciding, Xin Qiji and Bi Zaiyu immediately began to act, and there were 30,000 defenders in Anxi Mansion, including 20,000 Song troops and 10,000 troops from the original Western Xia. And Xin Qiji was also worried about the lack of troops, so he transferred 10,000 horses from Liangzhou. At the same time, he ordered the Yinzhou Imperial Garrison to control Yang Changpeng, and asked him to immediately take 15,000 men and horses to ambush near Pingxi Mansion, waiting for an opportunity to capture Pingxi Mansion.

And the Ren clan really did not disappoint Xin Qiji and Bi Zaiyu, and after capturing Anxi Mansion, he immediately mobilized another 20,000 horses and horses to enter Anxi Mansion. After Xin Qiji and Bi Zaiyu received the report, they were also overjoyed, and this time the defenders of Pingxi Mansion were only a few thousand left, and the garrison was empty, and they were just going to attack. Therefore, he immediately ordered Yang Changpeng to attack Pingxi Mansion immediately. And Bi Zaiyu led 10,000 horses and set up an ambush on both sides of the Yellow River, preparing to attack while Ren's army was halfway through. Xin Qiji, on the other hand, gathered 10,000 horses from Xiliang Mansion, and as soon as Ren's army left Anxi Mansion, he immediately sent troops to recover Anxi Mansion.

Because it was an ambush in the wild, the 10,000 horses led by Bi Zaiyu were all cavalry. Anxi Road has just been established, everything is in the process of restoration and reconstruction, the conditions are a little simple, only the war horses are not lacking, now the entire Anxi Road together with the original Western Xia army, a total of about 100,000 garrisons, and the number of war horses has reached more than 50,000, more than half of the whole army, this is also the most exciting place for Bi Zaiyu, the army of the Great Song Dynasty, how to have such a large number of cavalry.

Therefore, Bi Zaiyu divided the 10,000 men and horses into two groups, and ambushed them on both sides of the Yellow River, waiting for Ren's men and horses to cross the river. And he also crossed the Yellow River and ambushed on the east bank, preparing to use the east bank of the Yellow River as the main battlefield to ambush Ren's army.

When Ren's army arrived at the Yellow River, it was dusk, and Bi Zai met Ren's army when they crossed the river, and he knew that although they had many men and horses, their army was not strong, and it was not difficult to deal with them. Just wait until it gets dark before attacking. After it got dark, Ren's army also crossed most of it, and Bi Zaiyu gave the order to order the Song army in ambush on the east bank to attack.

Ren's army was originally only a second-rate army left by the original Western Xia, the quality and training level of the soldiers were not high, and Ren Decong and Ren Chunli were not generals, so although hundreds of tents were set up on the east bank of the Yellow River, but only for rest, the tents were very scattered and disorderly, and the soldiers were lazy, thinking that they would finish their work early and rest early, and they did not set up defensive facilities such as fences and car walls. Not to mention the number of troops reserved for the guards. As the commanders of the whole army, Ren Decong and Ren Chunli don't care.

Some of the soldiers who were still eating had not yet put down their rice bowls when they heard a sharp sound of breaking through the air, and almost at the same time, a torrential rain of arrows fell on their heads. A scream immediately sounded in the position of Ren's army, and then the cavalry of the Song army rushed to the camp and launched a merciless killing and poking of Ren's army with spears and sabers.

Most of the soldiers of Ren's army were eating, unprepared for the sudden attack of the Song army, and immediately panicked, and in the dark, they did not know how many men and horses the Song army had, so they were beaten by the Song army from the beginning and were embarrassed. The clever ones who dropped their jobs and found a place to escape, and those who were slow to react would have died under the iron hooves of the Song army. The whole camp was in chaos.

Seeing that the enemy had no power to resist, Bi Zaiyu immediately ordered the 5,000 men and horses to be dispersed into dozens of squads of two or three hundred horsemen, and killed Ren's army separately. At the same time, he also issued orders to the Song army on the other side, ordering them to attack as well. So the cavalry of the Song army galloped across the camp of Ren's army, rampage, and constantly killed the enemy army who had no power to resist. Some Song soldiers took local materials, inserted spears into the fire that was cooking and heating with Ren's army, and picked it up hard, and the firewood with the fire immediately splashed everywhere, fell on the tent, fell on the baggage, and quickly spread.

And some soldiers have long been hiding in tents to sleep, even taking off their clothes and armor, some tents were burned, some were pulled by the Song army, some of the soldiers inside escaped, but many were trapped in the tents, burned to death or trampled to death by the Song army's war horses.

At this time, the Song army on the west bank of the Yellow River also launched an attack on the Ren army, and the Ren army remaining on the west bank of the Yellow River still had more than 10,000 people. Although the Song army launched an attack on the east bank first, so that the Ren army on the west bank was alert, but the two main generals Ren Decong and Ren Chunli were on the east bank, and no one on this side could organize men and horses to prepare for the battle, so after a fierce charge by the Song army's cavalry, the Ren army on the west bank was also quickly defeated.

Although the number of the Song army was only a quarter of that of Ren's army, and since it was on the east bank of the Yellow River, the number of Ren's army was almost six times that of the Song army, but this battle was not equal from the beginning. In the chaos, the soldiers of the Ren army crowded and trampled on each other in order to avoid the pursuit of the Song army, and they also suffered countless casualties. Many were squeezed into the Yellow River and drowned.

Ren Decong and Ren Chunli, who were resting in the tent, had already heard the movement outside, and when they walked out of the tent, the two of them were not dumbfounded, and they saw that the camp was full of firelight, shining as bright as day. The soldiers of Ren's army have been killed by the Song army, and their corpses are all over the field, and the blood is flowing in the ditch, and those who are alive are scattered to avoid the pursuit of the Song army. On the other side, although it is not very clear, but with the light of the scattered fires, it can also be seen that Ren's army has already been defeated under the fierce attack of the Song army.

Although Ren Chunli regarded himself as a famous general, in fact, he did not have any actual combat experience at all, so he was frightened by this hellish scene and did not move. My mind went blank, and there was nothing left. And Ren Decong has seen some of the world in the end, and he can still make correct judgments. The defeat of Ren's army is irretrievable, if you don't run now, you won't be able to leave when the Song army surrounds you.

Therefore, Ren Decong pulled his nephew, who had already been reluctant to give up, asked his own soldiers to prepare horses, and then asked the soldiers to help, put Ren Chunli on horseback, and under the protection of more than 100 personal soldiers, he fled to the northeast.

In fact, from the beginning of the war to the present, it has only been half an hour, and the Ren army on both sides of the Yellow River has been completely defeated. Bi Zaiyu felt that it was a little hard to believe that it was smooth, and this victory came too easily. Therefore, he immediately ordered all armies to reduce the number of killings, and began to persuade the enemy to surrender, capture more prisoners, and regain the fruits of victory.
