It was precisely because of the timely reminder of the second Khan Anluo that Sha Bolu Khan was sent by Apo to make Sui's dizzy mind calm down, and then realized that once he led the army to turn around and march westward, and changed the attack on Sui to conquer Apo, Wuyuan City and even Dujin Mountain would be in danger, so he immediately issued a military order: the troops were divided into two routes, and he and Datou Khan led the army to turn around and march westward to conquer Apo: with Kuhezhen as the vanguard, he commanded his own tribe's 50,000 troops, with Anluo as the main general, led 70,000 soldiers and horses from his headquarters to aid Wuyuan City.

Yuwen Panruo saw that she had worked hard to instigate the five Turkic khans to join forces to attack Sui and was about to be destroyed by the separate peace between Apo and Sui, and she was afraid that it would be difficult to restore the old days of her Yuwen family from now on, and she couldn't help but feel sad and burst into tears.

Unable to persuade Sha Boluo to continue to attack Sui, Yuwen Panruo was originally a very powerful and scheming person, so he forced himself to hold the disappointment and loneliness in his heart, and took the initiative to make a request to Sha Boluo, willing to follow Sha Boluo to the west to conquer Abo, and the husband and wife never gave up.

Sha Boluo felt ashamed of his beloved wife, so he comforted Yuwen Panruo and said: "Ke He Dun, please rest assured, when I lead the army to destroy Abo's ungrateful boy, I will definitely raise a large army to attack Sui again to avenge my in-laws." ”

For the time being, he left Sha Boluo and his wife to lead the army to the west to defeat Apo Buti, turned around and said that he led the army back to the Anluo and Cave Hezhen in Wuyuan City.

Zhou Shao, the head of the march under Yang Shuang's command who stayed in Baidaozhou, discovered the main Turkic army that suddenly appeared outside the city of Baidaozhou.

The rise of the Turkic Khanate in the Mobei steppe was decades before the opening of the Sui Dynasty. Although in the long process of the development and growth of the Turkic tribes, the ancient tribal alliance system was still retained, and the five Turkic khans each had their own territories and tribes, and even the army, which went their own way in peacetime, and only in military affairs must uniformly obey the orders of the Great Khan, but gradually formed a set of their own official system.

There were 21 official positions in the Turks, of which the first 10 official positions had to be appointed by the Grand Turkic Khan himself, and the other four khans only had the power to appoint middle and lower ranks. Among the twenty-first rank official positions, Ye Hu is respected, and the next one is set up, and the special service is ...... In addition, the Turks followed the example of the Northern Dynasties and also implemented the official system of separating officials and lords, for example: the Turki Khan was at Luoyu, whose title was Khan, which was equivalent to and slightly higher than that of the prince of the Sui Dynasty, and his official position was the first-class official position of Ye Hu, which was equivalent to the Shangshu Order of the Sui Dynasty.

The position of special service held by Gu Hezhen is roughly equivalent to that of the Sui Dynasty's Shangshu Provincial Servant, and it is also a high-ranking official position. Therefore, although Dye Gan is a Turkic prince, he can only serve as a vanguard and obey the command of Gu Hezhen.

On the way to lead the army back to Wuyuan City, he learned that the marshal of the Sui Dynasty's Hebei Road march personally led tens of thousands of troops north out of Yanmen Pass and attacked Wuyuan City, and he immediately ordered the vanguard Dye Gan to lead 10,000 horses from his headquarters to the northeast to march all the way to reinforce Wuyuan City, and he himself led 40,000 troops to march straight to Baidaozhou, hoping to recapture Baidaozhou from the Sui army in the shortest possible time and cut off the retreat of the Sui army to the pass.

At the same time, Gu Hezhen also sent people to make suggestions to the second khan Anluo, suggesting that Anluo and his 30,000 elite iron cavalry in the tribal army should follow after Dyegan, gallop to the aid of Wuyuan City, and strive to attack the defenders in the city before the Sui army captured Wuyuan, and annihilate the Sui army under Yang Shuang's army under Wuyuan City in one fell swoop.

Because Zhou Shao, who stayed in Baidaozhou on the Sui army, was surrounded by Turks layer by layer soon after discovering the army under the command of Gu Hezhen, he successively sent two scouts to Yang Shuang to report for help, in addition to the tens of thousands of Turkic troops led by Gu Hezhen, there were two Turkic men and horses who were diagonally inserting in the direction of Wuyuan, which led to Yang Shuang, the commander of the Sui army, making a wrong judgment on the entire battlefield situation, especially the comparison of the military strength of the enemy and us.

Zhou Shao knew the importance of Baidaozhou's gains and losses to ensure the safe retreat of the entire Northern Expedition to Yanmen Pass, although he knew that Baidaozhou had only been attacked by the Sui army led by Yang Guang not long ago, most of the city walls were seriously damaged, and the strength of the defending force was far less than the enemy's siege force, and he would face a difficult situation that was easy to attack and difficult to defend, but he still personally went into battle, inspired his soldiers, and swore to defend Baidaozhou to the death, and reserved the only way to retreat for the army of Weiwang.

The siege strategy adopted by Gu Hezhen was very simple, that is, to surround it on three sides, attack one side, concentrate nearly half of the soldiers, horses, and equipment, and launch a round of fierce attacks on the west gate of Baidaozhou.

The Turkic army did not focus on attacking the city from the north and south, but only launched a strong attack from the West Gate, which was not very important in Zhou Shao's eyes, forcing Zhou Yao to urgently transfer the sergeants who were mainly deployed in the north and south to the West Gate to fight, and virtually gave up the hope of leading the army to break through, striving to meet Yang Shuang's troops in the north, and retreating to the Yanmen Pass in the south.

The battle near the west gate of Baidaozhou lasted for a day and a night, and the battle was no less tragic than the battle when Yan Rong led his army to capture Wuyuan City.

After paying the price of the lives of thousands of Turkic soldiers, the western city wall of Baidaozhou, which was not very strong, finally collapsed under the repeated attacks of the Turkic army, and a large number of Turkic soldiers rushed into the city like a tide.

Zhou Yan watched as the city had been breached by the Turkic army, sighed on his back, pulled out his saber, and wanted to kill himself, but was desperately stopped by his own soldiers around him. More than a dozen pro-soldiers supported Zhou Shao, disguised and disguised, mixed with the people in the city, taking advantage of the fact that the Turkic army had just broken through the city, and was making every effort to pursue the remaining defenders in the city, quietly slipped out of the south gate of Baidaozhou, and fled back to Yanmen Pass.

At the same time as the capture of Baidaozhou by the Guhe Zhensuo, Du Yan, the head of the Sui army's march, led an army of 40,000 troops less than a hundred miles south of Wuyuan City and collided head-on with the Turkic reinforcements led by Ran Gan.

Although Dye Gan was anxious to rush to Wuyuan City to rescue his father's Luo Yu out of the siege, he also learned the lesson of the battle with Daxi Changru in Zhoupan, and did not rashly attack the Sui army that went south to reinforce, but listed 10,000 horses under his command at the Tongjin Pass, blocking the Sui army's passage south to reinforce Baidaozhou.

Relying on the superiority in troops, Du Yan commanded the whole army to launch three rounds of attacks on the Dyegan Department in succession, but failed to break through the opponent's defense line. At dawn the next day, when Du Yan led the few cavalry in the army to launch a fourth round of attacks on the enemy troops blocking the way, he was surprised to find that the number of Turkic troops blocking the road in front had increased by tens of thousands overnight, and all of them were Turkic iron cavalry.

Seeing this situation, the first thought that flashed through Du Yan's mind was: Bai Daozhou can't be saved.
