Li Yuan led 30,000 soldiers and horses borrowed from Yang Jun's command from the eastern capital to the north to rescue Bingzhou, and at the same time, Yang Yong, the crown prince of Xianyang Beihu, received a report that the main Turkic force had suddenly turned around and moved westward.

According to the military strength of the Sui Dynasty in the northwest region, headed by the crown prince Yang Yong, assisted by the new right leading general Yu Wenxin, who was in charge of the northwest defense, Guanzhong, mainly stationed in Honghua's right servant Yu Qing led 50,000 soldiers and horses to defend; In the area of Longyou, a force of nearly 100,000 soldiers and horses composed of 30,000 troops led by Dou Rongding, the general of Zuo Wuhou, and 50,000 or 60,000 people who volunteered to join the army through amnesty, fought against the Apo Khan's department, which was second only to Shabalu in strength among the five Turkic khans.

It only took a dozen days of effort, and the main force of Sha Boluo had already broken into the north bank of Weishui, why did he abandon Xianyang and Chang'an, which were facing each other across the bank, overnight, and turned around and drove westward?

After Yang Yong heard the news in Xianyang City, he was afraid that there would be fraud, so he sent multiple scouts to inquire about the news. Three days later, a scout came to report: because Dou Rongding repeatedly broke the Apo Khan, Changsun Sheng persuaded the Apo Khan to send envoys to Chang'an, wanting to make peace with the Sui Dynasty.

When the scout returned to Xianyang to report the news to Yang Yong, Yuwen Xin was also present, and when he heard the news, Yuwen Xin was overjoyed, and immediately asked Yang Yong to order Yu Qing Ze's troops to cover up and kill from behind, and defeat the Turks.

Yang Yong got the exact news of the Turkic retreat, so he breathed a sigh of relief, and waved his hand to Yuwenxin again and again: "Now that the 200,000 troops of Jianghuai have not yet returned to Guanzhong, we are still at a disadvantage compared with the strength of the enemy and us. ”

Yu Wenxin was idle at home for nearly a year, and this time he came back to assist Yang Yong in taking charge of the army, eager to establish military merits, and win the trust of Yang Jian's father and son, so as to take advantage of the situation to seize military power and create conditions for the future anti-Sui Fuzhou, so he ignored Yang Yong's opposition and insisted on personally leading the army to carry out a counteroffensive.

Yang Yong led the three armies for the first time, and had no actual experience in leading the army, and Yu Wenxin was known for his prestige in the former Korean army, so he couldn't help but insist on it again and again, so he handed him 3,000 men and horses, and ordered him to lead the army across Weishui to recover the lost territory.

Although Yuwenxin only got 3,000 men and horses from Yang Yong, and Yang Yong only ordered him to lead the army to recover the lost territory, and did not ask him to take advantage of the Turkic withdrawal to carry out a counterattack, but once the military power was in hand, Yuwenxin started his own idea.

After he led his army across Weishui and successively recovered several empty cities that had been captured by the Turks, he did not pursue the main Turkic forces advancing westward, nor did he turn around and continue to regain the lost territory to the south, and joined Yu Qingze's troops stationed in Honghua, but went straight north and led 3,000 men and horses to Yunzhou.

At that time, Yunzhou City was already part of the territory of the Turks, and it was an important city connecting the Eastern and Western Turks (in the second year of the emperor's reign, the Turks had not yet formally divided into the Eastern and Western Turks, and here only referred to the geographical location). Yuwenxin planned to take advantage of the opportunity of the main Turkic force to march west to defeat Apo, and led the army to capture Yunzhou City in one fell swoop, so as to achieve the first victory of this Turkic counteroffensive and lay the foundation for stealing military power in the future.

Sha Boluo was not a mediocre person, and while personally leading the main army to the west to conquer Apo, he naturally left a heavy garrison in Yunzhou.

There are only 3,000 soldiers and horses under Yuwen Xin's command, and with this little force alone, it is more difficult to take Yunzhou City through a strong attack than to ascend to the sky. So, Yuwen Xin cleverly found dozens of young women from the local people, and ordered his sergeants to disguise themselves as the family members of these women, and take these women to walk back and forth outside Yunzhou City every day, pretending to be refugees, so as to attract the attention of the Turkic defenders in Yunzhou City.

Sure enough, only two or three days later, the Turkic defenders on Yunzhou City could not resist the temptation of the women outside the city, and sent a team of men and horses to capture the sergeants under Yu Wenxin and these women into Yunzhou City.

In the evening of the same day, Yu Wenxin personally led the men and horses, and the sergeants who had previously mixed into the city should be outside, put a few fires in the city, took advantage of the chaos to capture Yunzhou in one fell swoop, and achieved a great victory in Yunzhou with less victory, the Turkic generals who stayed in Yunzhou City were woken up by their own soldiers in their sleep, and before they could lead the army to resist, they were cut off by Yuwen Xin's head, and thousands of remnants of the defeated soldiers were driven out of Yunzhou City by the Sui army, and they fled west in embarrassment, and went to report to Sha Boluo.

The victory in Yunzhou was another important victory since the Sui Dynasty started the war with the Turks, following Yang Guang's army to recover Baidaozhou. It not only enabled Yuwenxin to regain the trust of Yang Jian's father and son with this battle, but more importantly, Yunzhou City was unexpectedly lost to the Sui army, cutting off the retreat of the Sha Boluo army back to Dujin Mountain, which directly affected the life and death of the 60,000 army led by Yang Shuang of Wuyuan City.

According to the results agreed with Yang Guang, Zhang Wei, Wang Shao and others, Li Che led 10,000 soldiers and horses north out of Yanmen Pass to meet Yang Shuang's army to withdraw to Guannei, but when Li Che led the army to the outside of Baidaozhou, he was disappointed to find that with the 10,000 men and horses he led, it was impossible to take Baidaozhou from the Turkic army, and then achieve the goal of receiving Yang Shuang's army to withdraw to Guannei safely.

After recovering Baidaozhou from Zhou Shao, he foresaw that the Sui army was likely to come to seize the only way to withdraw his troops, and at the same time ordered the soldiers to step up the repair of the damaged city wall, he also set up three large battalions on the left, center and right in the south of Baidaozhou, each of which stationed 10,000 soldiers and horses, in case the Sui army in Yanmen Pass came to seize Baidaozhou.

The three large camps formed a horn with each other, and they were arranged in the south of the city of Baidaozhou, and if the Sui army wanted to attack the city, it must break through the three large camps. Li Che led the army to the vicinity of the city of Baidaozhou, and sent a small group of men and horses to tentatively launch an attack on the Turkic camp in the center, but without waiting for the Sui army to attack near the camp gate, the two Turkic battalions on the left and right respectively sent thousands of soldiers and horses to respond, and the three directions attacked together, almost annihilating all the 2,000 men and horses sent by Li Che.

Due to the serious shortage of troops, the 10,000 horses led by Li Che could only meet each other to carry out a small-scale attack on the three large Turkic battalions outside the south gate of Baidao Prefecture, and it was difficult to directly threaten Baidao Prefecture, so that Yang Guang and others' plan to send troops out of the pass to meet Yang Shuang completely failed.

There is a way to lose the east corner, and gain the mulberry elm. Although the plan to send troops out of the pass to attack Baidaozhou fell through, the letter written by Yang Guang to the Turkic Khan Chu Luo Yu that was robbed by Gu Hezhen Bandao played an unexpected role, making the chief general of the Turkic East Route Army, the Second Khan Anluo, suspicious of Chu Luo Yu's secret communication with Sui, and then objectively created a glimmer of life for Yang Shuang's army.
