Youzhou governor Li Zhen learned that the Turkic army broke through the Great Wall of Shacheng, captured Dingzhou, and outflanked the news of attacking the state from the east road, because he was eager to rush to the aid of the state, so he only led two thousand Sui troops to attack the city, but was driven back by the news of the Turkic East Road army commander Gu Hezhen led the army to surround the city, fought hard for many days, and finally because of being outnumbered, Li Zhen himself and two thousand Sui soldiers were killed in the city.

Although the whole army of Li Zhen's department was annihilated in Shacheng, it greatly aroused the determination and confidence of the people in Dingzhou City to resist the Turkic occupation, and at the same time that Gu Hezhen led the defenders of Dingzhou to recapture Shacheng from the Sui army, many people in Dingzhou City spontaneously organized and burned down many granaries of the Turkic army, and the officers and troops who came from Fanyang, Bohai and other places successively attacked the Turkic camp and killed a small group of Turkic soldiers, so that the Turkic army left behind in Dingzhou City was worried and panicked all day long.

The news spread to the Sui army camp in the east of Bingzhou, Yang Guangzheng wanted to order the soldiers of the three armies to kill the invading Turkic army with one blow, and then turn defense into attack, taking advantage of the situation to launch an attack on Dingzhou, but at this time, Li Che, who was guarding the north road of Bingzhou City, sent people to bring Yang Guang another good news: Yan Rong, the head of the Sui army's march, had led his men and horses to successfully recapture Yanmen Pass from the Turks, cutting off the passage for the Turkic army to retreat outside the pass.

It turned out that Yan Rong captured Yanmen Pass with the Turkic army, and followed the defeated Sui army to march to Bingzhou on the night, but failed to effectively stop the Yongyu Lu army near Mayi, so he had a plan and withdrew to the Mayi military camp that night, so he ordered the generals and soldiers of the army to find the robes and uniforms of many Turkic merchants from the Mayi Mutual Market, and ordered hundreds of Sui soldiers to pretend to be Turkic merchants, and rushed to Yanmen Pass by small road, and falsely claimed to the Turkic army occupying Yanmen Pass that they were Turkic merchants who fled from Mayi Mutual Market to the outside of the pass, and fraudulently opened the city gate and mixed into Yanmen Pass.

After learning the news that Li Che led the Sui army and successfully blocked the Turkic army outside the city of Bingzhou, Yan Rong personally led the 10,000 Sui troops under his department, and went the opposite way, starting from Mayi to the north, and unknowingly sneaked to the outside of Yanmen Pass, and joined forces with the inner Yingli and the outer part of the city that had been mixed into the city, recaptured the Yanmen Pass from the Turks, and drove the Turkic troops who remained in the city outside the pass.

After Yan Rong captured Yanmen Pass, he sent a letter to Li Che, asking Li Che to fight with him in the north and south, and annihilate the nearly 100,000 troops led by Yongyu Lu in the area between Yanmen Pass and Bingzhou. After Li Che received the report, because he only had more than 50,000 remnants of the defeated generals under his command, and the strength was not enough to launch a counteroffensive against the 100,000 Turkic army, he immediately sent someone to report to Yang Guang, asking Yang Guang to mobilize the main force of the Sui army stationed in Bingzhou to go north, unite with his own troops, and launch a counteroffensive against the Turkic army.

There was a major turning point in the east and north roads at the same time, which made Yang Guang feel a little embarrassed while being overjoyed.

According to his original plan, as soon as the rebellion in Dingzhou broke out, it showed that the Sui army stationed in the eastern front of the prefectures marched west to aid and annex the state, which was a good time to attack from the east and west, recapture Dingzhou, and drive the Turkic army from the east and west. At the same time, I didn't expect Yan Rong to also surprise the army, in one fell swoop from the Turks to recapture the Yanmen Pass, directly cut off the retreat of the Turkic West Road army to the outside of the pass, so that the east and north roads have a major turning point to defeat the enemy, but the Sui army stationed near Bingzhou totaled only 1120,000 soldiers and horses, and through the battle of Yanmen Pass, it lost nearly 20,000 people, with less than 100,000 horses, and wanted to launch a counteroffensive against the Turkic army in the east and north directions at the same time, it was inevitably a little inadequate.

Just when Yang Guang was in a dilemma in the big tent and hesitated, he suddenly heard someone crying outside the tent and shouting: "Third brother, you died so miserably." Lord Wang, I want to lead the army to Dingzhou to avenge my third brother. ”

"Jin Cai, is it you outside the tent? Come in and speak. Yang Guang rushed from the city to the east of the city of the Sui army camp the next day, Duan Da led the hussar battalion soldiers to the east of the city camp to protect Yang Guang, only Li Hun alone, because of the heavy task of investigating the traitors, was left in the city of Bingzhou to monitor the movements of the monk Huilin, at this time identified outside the tent is Li Hun crying, shouting, Yang Guang's heart sank, guessing that he must have learned the news that the third brother Li Zhen died in the sand city, so he rushed to ask for his life, wanted to lead the army to Dingzhou, for Li Zhen to avenge, so he ordered him to enter the tent to speak.

Before Yang Guang's words fell, he saw Li Hun crashing into the tent in despair, threw himself down in front of him, and cried bitterly: "At the end of last night, I suddenly had a dream, dreaming that my third brother was covered in blood, and told me earnestly that behind him, I should take good care of my nephew Li Min, and I didn't want to hear the news of the martyrdom of my third brother early this morning." Lord Wang, please allow the general to lead the army to Dingzhou to avenge my third brother. ”

Yang Guang hurriedly got up and helped Li Hun up, and persuaded him: "Jin Cai, I also just got the report, I know the news that Manager Li has been martyred in Shacheng, and I am about to send troops to Dingzhou to avenge Manager Li, but I just ......" said, glanced at the scout who came to deliver the message on Li Che's order, and swallowed the rest of the words back into his stomach.

"The last general is waiting in the prince's tent today, when the prince decides to send troops to Dingzhou, the last general is willing to be a pioneer and lead the army to the expedition at any time." Li Hun immediately noticed that Yang Guang was hesitant and insisted unrelentingly.

"Send two managers to the tent to discuss the emergency military situation." Yang Guang thought about it, but still felt that it was difficult to make up his mind and concentrate his forces on which way to attack first, so he gave instructions to the sergeant standing at the tent.

Du Yan and Zhou Shao, the two marching commanders, were ordered to come, and listened to Yang Guang's introduction of the major turning point on the North Road, and then looked at Li Hun, who was crying silently and stubbornly refused to retreat in the tent, and also felt that the matter was very important, and it was difficult to make a decision in a hurry.

Both of them understood that from the perspective of relieving the siege of the annexed states, it seemed more important to concentrate forces to attack from the north and south and repel the Turkic army on the western route, but at the same time they gave up the counteroffensive on Dingzhou, but it was likely that the Turkic army on the eastern route would also change their strategy, give up outflanking the annexed state, and instead attack the eastern front, which was extremely unfavorable to the entire Hebei war situation.

After thinking for a long time, Du Yanfang tentatively clasped his fists and said, "Didn't the marshal already report the military situation here to the imperial court?" If the imperial court had already sent reinforcements to the annexed state, the general would have thought that he could choose to counterattack Dingzhou first and expel the Turkic East Route army from the Guanwai, on the contrary, if the imperial court reinforcements could not arrive for a long time, it seemed appropriate to relieve the siege of the annexed state first. Everything is up to the marshal's decision, and we are willing to obey the general's orders. ”

As early as Zhao Cai found out about the deployment of the Turkic invasion of the south, Yang Guang asked Chang'an for help, but he had not yet received a reply from Chang'an, hearing Du Yan's words, he shook his head and responded: "The current situation can only be based on the existing forces, and you can't expect the imperial court to send reinforcements to the north." If this is the case, according to the opinion of Governor Du, should we first increase the troops on the northern road and relieve the siege of the annexed states, and then make plans? ”
