Budugen is cunning and flexible.

Now that the Han army is strong, Xianbei in the central part is a lesson from the past, and he will never fight hard with the Han army.

The grassland tribes worship the wolf nature, so they learn the characteristics of the wolf, patience is the most necessary, can be patient with the enemy for a long time, find a good opportunity, hit the enemy, quickly kill the enemy.

Without the drag of the people, Bu Dugen decided to withdraw from Yunzhong City and go west, if the Han army pursued, it would inevitably lengthen the baggage transport line, and he could implement a flexible strategy of detouring and sneaking up on the Han people's baggage transport team to force the Han people back.

At the beginning, the Xianbei king Tanshi Huai used this method to defeat the attacks of the Han army many times.

Bu Dugen divided the army into two, and one part was led by the lieutenant general to Xianyang City to be stationed as his reception; Xianyang City is less than 100 miles away from Qiyang County, and it is easier to get the support of the leader.

He personally led half of his cavalry to hide on the west bank of the deserted water, waiting for the best opportunity to attack.

The distance to transport the baggage from Wuyuan County to Cloud City was too long, and this move was retreated, which reduced the logistical pressure, and the situation was very favorable to Budugen.

Wen Chou learned through the scouts that the Xianbei army had withdrawn from Cloud City and retreated to the west of the barren water, and he had a general insight into Budugen's thoughts in his heart, and like his plan, he wanted to lure the enemy out of the hole and choose the opportunity to destroy the opponent, and now it depends on who can bear it better.

However, this is in line with Wen Chou's intention, the tactic of steady and steady progress, city by city.

So he ordered Xu Lin to lead 5,000 cavalry to occupy Shaling County, and he was not allowed to attack without orders; Send Xue Yin to lead his headquarters into Yunzhong City, and clear the Xianbei scouts between the two rivers.

Anyway, he was already the Taishou of Yunzhong County, and he didn't take his false name very seriously, so he gave up the honor of recovering Yunzhong City to Xue Yin, and the honor of recovering Shaling City to Xu Lin. Although it is the recovery of two empty cities, the significance is extraordinary.

Xue Yin was moved to tears, and after looking forward to it for so many years, he finally realized his long-cherished wish.

Later, Wen Chou sent several cavalry to sweep the territory east of Baiqushui, and be sure to clear the hidden Xianbei scouts; And let Xu Fu lead the people of the headquarters to Beiyu, Wuquan, Yuanyang, Dingxiang and other counties in the northeast to patrol and defend, to ensure the safety of the flanks, to avoid the Xianbei people's roundabout side attacks, threatening the safety of the baggage and the rear road.

There was no grazing for a long time, and the grassland was lush with pasture, and it was very easy to hide from the Xianbei scouts, so the cavalry sent had to carefully observe and search.

Wen Chou was not in a hurry to attack, but first stabilized the territory he was occupying, consolidated and repaired the existing city, and ensured the smooth transportation of logistics and materials.

Wen Chou left a cavalry to garrison Chengle County, and then led the cavalry and the Koji people under his jurisdiction to garrison Yunzhong City.

After stabilizing the defenses east of the wasteland and clearing the Xianbei scouts, Wen Chou began to consider an offensive plan.

The scouts sent back a lot of information that there were only more than 4,000 Xianbei cavalry in Hexi, and Wen Chou decided to encircle and annihilate them with superior forces.

The Han army did not attack for a long time, and it was very impatient to wait. The weather in October was already very cold in Yunzhong County, and it was necessary to wear cotton clothes, while the Xianbei cavalry was still single-clothed and single-coated, and the food supply was not sufficient, and the soldiers' lives were very difficult, and there was a great deal of resentment.

Budugen has already intended to withdraw his troops.

The Han army lived in the city, with houses to protect from the wind and rain, thick cotton clothes to keep out the cold, and the diet was also very rich, and the life was very good, and the morale was high, and they all wanted to win the head of the Xianbei people in the next war, and get rich rewards, so as to have a comfortable New Year.

At this time, Wen Chou was ready for a full-scale attack, and the scouts had determined the location of Budugen's camp.

On the evening of October 14, the moon hung high, and the earth was very bright, which was very suitable for night marches.

The officers and men quickly erected the pontoon bridge, and the cavalry troops crossed the deserted water at midnight, opening the prelude to the encirclement and annihilation of Budugen.

Xu Lin crossed from the lower reaches of the river, and his task was to make a detour back to the rear of Budugen and cut off his escape path.

Wen Chou led the army across the river from the western part of Cloudsdale City; accompanied by Xue Yin and Xu Zhen; Xu Zhen was the earliest person to follow Gao Shun, and he was very trusted by Gao Shun, and Wen Chou must be given the opportunity to make meritorious contributions.

Only the Koji people and his fortified battalion were left behind to defend Cloudsdale.

Originally, Xue Yin suggested that Xu Lin go to raid Xianyang City to avoid the escape of the four thousand Xianbei people there, but he was vetoed by Wen Chou, and it was better to cut off one of his fingers if he injured the enemy.

Bu Dugen was not easy to follow, in the front of the camp, a secret force was arranged every ten miles, and there were a large number of scouts to jointly monitor the movements of the Han army.

After the wee hours of the morning, the scouts arranged by Budugen had detected the movements of the Han Chinese army and were quickly reported to Budugen.

The Xianbei people have lived on the grassland for so long, and the living environment is very harsh, and they have long been trained to be very vigilant, and a large number of cavalry moves, and they can judge the number and speed of the enemy army by the vibration of the ground dozens of miles away.

After receiving the report, Bu Dugen was overjoyed, the Han army finally divided its troops to fight, and also sent a small army, wanting to go around behind him, it was really a dead act.

Immediately gather the officers and men, set off overnight, and quickly retreat to the northwest. Bu Dugen prepared to avoid Wen Chou's army, focusing on Xu Lin's 5,000 cavalry, and then retreated to Xianyang City, continuing to stretch the Han army's logistics supply line, and choosing an opportunity to fight again.

Budugen has been here for so long that he is very familiar with the terrain.

sent a small force of cavalry to the place where Xu Lin's army passed to set up traps and tripping horse ropes; He personally led the army to lie in ambush in a suitable position, and after waiting for the arrival of the Han army, he launched a fierce attack on the flank and waist of the Han army, striving to defeat the Han army's formation in one fell swoop.

The Han scouts were not vegetarians either, and soon detected the traps set by the Xianbei people, and after losing a few people, they retreated decisively and returned to the large army to report to Xu Lin.

After receiving the report, Xu Lin immediately changed the original route of the march and continued to detour westward, avoiding the danger of being ambushed; and sent someone to report his whereabouts to Wen Chou, as well as information that the Xianbei people might have set up an ambush.

Budugen couldn't make a plan, and there was the danger of being surrounded by the Han army, so he didn't dare to slack off, and immediately led the army to retreat to the southwest. Or force them to the banks of the Yellow River to fight them.

Budugen was very confident, and felt that in the field battle on the vast plain, his 4,000 cavalry would definitely be able to defeat the 5,000 cavalry of the Han people.

There is a very big difference between the cavalry of the two sides, the cavalry of the Han army is one person and one horse, and the Xianbei people are all one person and two horses, the centurion and the thousand-sized commander are one person and three horses, although the war horses of the Han army are superior to the war horses of the Xianbei people, but the long-distance march is still not as fast as the Xianbei people.

Soon, Budugen ran in front of Xu Lin, lined up in formation, and waited for Xu Lin's arrival.

The scout quickly fed back the news, and Xu Lin ordered the troops to stop advancing as a decoy to attract the Xianbei cavalry, and immediately sent someone to report the news to Wen Chou, hoping that Wen Chou would move forward quickly, detour back to the back of the Xianbei cavalry, and encircle the Xianbei people.

When Wen Chou learned the news, he quickly moved closer to the direction where Xu Lin was, even if he couldn't encircle and annihilate the Xianbei cavalry, he couldn't put Xu Lin in danger.

The ground shook violently, and Bu Dugen guessed that a large army of the Han army was coming, and now if the small force attacking Xu Lin would fall into a melee, and the Han army would take advantage of the situation to surround them.

After careful consideration, Budugen decided to withdraw his troops, and he did not dare to risk his life.

The Xianbei cavalry was irritable, and now they couldn't fight, and the withdrawal was not smooth, and their bodies were cold and hungry, which was too uncomfortable.

Bu Dugen ordered to retreat back to Xianyang City, and the Xianbei people were very supportive, in their opinion, the grassland is so big, where can it not be accommodated? Why fight to the death against the Han Chinese? This is not in line with the tactics of the original King of Tanshi Huai.

The Xianbei people retreated, and Wen Chou was very angry, so he decided to chase all the way, and after finishing his work, he must recover the entire territory of Yunzhong County.

Bu Dugen quickly detected that the Han army had nearly 20,000 cavalry, and they did not dare to fight hard, even if they had the protection of Xianyang City, it was not safe, so he urgently ordered the garrison of Xianyang City to prepare for retreat, and strive to make peace with the leader of Qiyang County as soon as possible.

Wen Choubai was busy for a while, and did not behead a Xianbei person, and the joy of recovering Yunzhong County has been diluted.

Xu Lin was ordered to be the governor of the west, and he led 5,000 cavalry to garrison Xianyang, while he led his troops back to Yunzhong County.
