Although Yan Rong, the head of the Sui army's march who led the army to recover Yanmen Pass, was unwilling to let the Turkic West Road army led by Yongyu Lu go out of the pass easily, due to the military orders of Yang Guang and Li Che, he did not dare to disobey the order, so he had to temporarily lead the army to withdraw from Yanmen Pass, making way for the people of Yongyu Lu to retreat. www.biquge.info As Zhou Shao expected, Yongyu Lu was anxious to lead the army to withdraw from the pass safely, and did not leave soldiers and horses to guard the Yanmen Pass, so after the Turkic army withdrew from the pass, the Yanmen Pass returned to the hands of the Sui army.

From the outflanking of the Turkic armies in the east and west, until the army of Yongyu Lu and Dyingan was ordered to urgently withdraw outside the pass, the war between the Sui Dynasty and the Turks lasted for more than a month in the summer and autumn of the third year of the emperor's reign.

During this period, the Sui army, because the Yanmen Pass was broken by the Turkic army undeclared war, the number of soldiers who died on the battlefield was as many as 20,000 people, and then, in the sand city, the loss of Youzhou governor Li Zhen, the two cities of Dingzhou and Shacheng were forcibly captured by the Gu Hezhen Department of the number of people outside the pass is also as many as 10,000, and the Turkic side, in the process of this southern expedition, a total of more than 30,000 people and horses were lost, and did not realize the battle intention set by the Sha Bo strategy before the war - to capture the state, to be fair, the two sides can be a draw.

Ten days after the end of the war, the new marshal of the Hebei Provincial March, Shangshu's right servant Yu Qing led 100,000 reinforcements to Bingzhou, and at the same time, brought an exciting news to the officials of Hebei Province, including Yang Guang himself: in view of the fact that the Turks had repeatedly raised troops to invade the border passes since the opening of the Sui Dynasty, the emperor had decided to send a large army out of the pass, take the initiative to attack the Turks, and extinguish their arrogance.

Yang Guang handed over the command arrow to Yu Qing, and accompanied him to review the local government army in Bingzhou, and the two returned to the main hall of Jinyang Palace and sat down, Yang Guang said to Yu Qingze: "Yu servant shot the edict of the emperor, and the army will soon be in the north to conquer the north, and the supply of grain and straw for the army should be raised by the king. I don't know if there is anything else that Yu Servant needs to help with this king? ”

Yu Qing since the opening of the Sui Dynasty, once because of the theft of the house, after being ordered to move to the northwest, successfully blocked the Turkic five khans army southward and regained reuse, this time led the army north to conquer the Turks, although there was an emperor's edict to appoint him as the marshal of the Hebei Road march, but since the town has been out of the north of the town has repeatedly performed well, in the court in the prestige of the Jin King Yang Guang still can't help but have a sense of awe, for fear of repeating the mistake of the king of Wei Yang Shuang, and Yang Guang broke up unhappily, disgraced to return to Chang'an. Therefore, when he heard that Yang Guang took the initiative to take on the important task of raising food for the northern army, he didn't know whether he was out of gratitude or panic, so he hurriedly stood up from his seat and replied very respectfully: "Your Royal Highness is a nobleman of the heavens, and the prince of the court who went out of the town to serve as a vassal is willing to bow down to prepare for the grain for the army, which makes Qing admire it." This time, Qing Ze was ordered to lead the army out of the pass to attack the Turks, and he did not dare to boast of victory in front of His Highness, but it was still possible to expel Sha Boluo from Baidao Prefecture, so please wait for good news in Bingzhou. ”

Since Yang Guang and Yu Xiaoren were classmates and friends when they were too young, they usually regarded themselves as juniors in front of Yu Qingze, and when they saw him get up to answer, they also stood up and politely conceded: "Yu Servant shoots no need to be polite, please sit down and talk." This king still has a small matter to ask for, and he hopes that Yu Servant will not refuse. ”

"Your Highness has orders, and Qing will do his best to serve them."

Yang Guang smiled and waved his hand at Yu Qingze, motioned for him to sit down, and said: "Some time ago, when the Turkic army invaded the south, before the withdrawal of the army from Dingzhou, Guhe Zhenlin had forcibly captured thousands of people from Dingzhou, including Jiang Tuozi, a flower worker who had been on duty in the palace for many years. ”

Yu Qing heard that although the things that Yang Guang entrusted him to do were small, they were not easy to do, so he groaned slightly, and replied with his fists: "Do you ask Your Highness to send a person who is familiar with Jiang Tuozi to accompany Qing Ze on the expedition, so that he can distinguish between serious and false at that time?" ”

Yang Guang heard that Yu Qing was reasonable, and was about to send his close guard Xian Yuluo to go out with the army, when the words came to his lips, he thought about it, and remembered that Yu Xiaoren and Jiang Tuozi were not strangers, and sent him to go out with his father to conquer the Turks, and he could also take the opportunity to test him to find out if he leaked the news that he led the army to attack Yuannina Mountain to the Turks, so he smiled and said to Yu Qingze: "Brother Ling Gongzi Xiaoren is quite familiar with Jiang Tuozi, so you might as well order him to go out with Yu Gong, and you can respond to Yu Gong's request, and when the time comes, you can distinguish between serious and fake, Second, you can also guard Yu Gong's side, which is convenient for taking care of daily life, what do you think? ”

Bring Yu Xiaoren to go on the expedition together, this is a good thing that Yu Qingze never dreamed of, once the northern expedition wins, his son can naturally set up a military merit, and the promotion of officials will be rewarded, it is a sure thing, Yu Qing heard this, hurriedly stood up for the second time, and expressed his gratitude to Yang Guang.

"I am a brother and sister with filial piety, and for trivial matters, Yu Gong doesn't have to thank him so much. Yu Gong served as the marshal of the Hebei Road march, and was in the imperial court, some time ago when the Turks invaded the south, Youzhou governor Li Zhen to relieve the siege of the state, led the army from the eastern front to help, unfortunately died in the sand city, Yu Gong led the army to the north this time, the post of the head of Youzhou should not be vacant, the king wants to jointly sponsor the head of the march Zhou Shao temporarily as the head of Youzhou, to ensure that the states of the eastern line are safe, I don't know if Yu Gong is willing? ”

If it were Gao Ying and Su Wei, even if Yang Guang proposed to him in person to sponsor someone for a certain position, most of them would be willing to agree to this matter after understanding many aspects of them, while Yu Qing was very different, and he didn't think about it, so he readily agreed: "The person sponsored by His Royal Highness is a talented person who is superior to Wen Taowu, and Qing should recommend it to the imperial court." ”

The two talked happily, and the topic unconsciously turned to the top of the Northern Expedition to the Turks, Yang Guang asked Yu Qingze: "Father's edict ordered Yu Gong to lead the army out of the pass to attack the Turks, but only handed over 100,000 soldiers and horses to Yu Gong, plus the local government army in Bingzhou, the total strength is only 200,000, and as far as I know, there are no less than 300,000 soldiers and horses under the command of Sha Boluo alone, with 200,000 against 300,000, does Yu Gong have a good strategy to defeat the enemy?" ”

At this point, Yu Qing signaled to retreat left and right, and only he and Yang Guang were left in the hall before he replied in a low voice: "Back to Your Highness, although Qing Ze led only more than 100,000 horses this time, it was clear from His Majesty's explanation before Chang'an left, and Qing Ze took advantage of the Turkic civil strife to lead the army to recover Baidaozhou and weaken the strength of Sha Boluo's family as much as possible. Therefore, it seems that our army has less than 200,000 soldiers and horses, but Sha Bo slightly has to face simultaneous attacks from the west and south, if you count the 200,000 troops under the command of Apo and Datou Khan, then this time Sha Bo will face nearly 400,000 troops, not hundreds of thousands of our Great Sui army. ”
