Xuanzong appointed Li Yi, the king of Wu, as the Taishou of Lingchang and the envoy of the capital of Henan.

Jia Ben arrived at Yongqiu first, where there were only more than 2,000 soldiers.

Previously, Yang Wanshi, the Taishou of Qian County, surrendered An Lushan, and forced Zhang Xun, a native of Hedong, to be his long history and go west to meet the rebels.

Zhang Xun arrived at Zhenyuan, led the officials and people to cry and worship in the temple of Emperor Xuanyuan, and then raised troops to fight against the rebels, thousands of people responded to his army, Zhang Xun selected 1,000 elite soldiers to reach Yongqiu west, and joined forces with Jia Ben.

At first, Yongqiu County ordered Fox Chao to lead the county to surrender to the rebels, and the rebels appointed him as a general, and asked him to lead his troops to Xiangyi to attack the official army from Huaiyang, so that Fox Chao was victorious, captured more than 100 people, locked up in Yongqiu County, and prepared to kill them, and then went to see the rebel general Li Tingwang.

What he didn't expect was that the Huaiyang soldiers took the opportunity to kill the soldiers guarding them, causing the fox tide to leave his wife and son and flee, and Jia Ben led his troops to take advantage of the chaos to enter Yongqiu.

Gengzi (16th), Ling Huchao led the rebel elite soldiers to attack Yongqiu, Jia Ben went out to fight, and the soldiers were defeated and died. Zhang Xun fought hard to repel the rebels, so he also led Jia Ben's troops and proclaimed himself the vanguard envoy of King Wu.

On the second day of the first month of March, Linghu Chao and the rebel generals Li Huaixian, Yang Chaozong, and Xie Yuan led more than 40,000 troops to the city to prepare to attack the city.

The soldiers in the city were very frightened when they saw the menacing rebels, and they had no heart to hold on to the city.

Zhang Xun said to them: "The rebels are strong and strong, and they have a heart for themselves. If we were to attack by surprise, the rebels would surely be defeated by panic. If the rebels are thwarted in their siege, we can hold on. ”

Zhang Xun first sent 1,000 people to the city wall to guard, and he led another 1,000 people, divided into several teams, opened the city gate, and suddenly rushed out. Zhang Xun took the lead and rushed straight into the rebel formation, and the rebel soldiers and horses dodged in panic, and then retreated.

The next day, the rebels gathered troops to attack the city, erected stone cannons around the city, and fired at the city, destroying the towers and low walls.

Zhang Xun also erected a wooden fence over the city to resist the attack of the rebels. The rebels swarmed into the city, and Zhang Xunjiao's soldiers tied up artemisia grass and poured grease, and then set fire to the enemy, so that the rebels could not enter the city. He also took advantage of the rebels' loopholes and sent troops to attack.

At night, Zhang Xun ordered people to put down the soldiers with ropes from the head of the city, attacked the enemy camp at night, defended the city for more than 60 days, and fought more than 300 battles.

The rebels were unable to conquer Yongqiu, so they had to retreat. Zhang Xun pursued the victory, captured more than 2,000 Hu soldiers and returned, and the army was greatly boosted.

At first, An Sishun, the head of the household, learned that An Lushan was going to rebel, and took the opportunity to report the matter to Xuanzong.

After An Lushan rebelled, Tang Xuanzong did not ask for the crime because An Sishun had already reported it.

Ge Shuhan has always had a conflict with An Sishun, so he deliberately forged a letter from An Lushan to An Sishun, asked people to pretend to deliver the letter, and then caught the person who delivered the letter at the gate of Tongguan City and presented it to the imperial court.

Ge Shuhan took An Sishun's letter to the bandits, and listed An Sishun's seven crimes, asking Tang Xuanzong to kill him.

Bingchen (the third year of the first month), An Sishun and his younger brother An Yuanzhen were both executed for this incident. The family was exiled to Lingnan.

Yang Guozhong had the heart to help, but he couldn't do anything, seeing An Sishun die unjustly, after this incident, Yang Guozhong realized that he was not indistinguishable in the imperial court, and began to fear Ge Shuhan.

Guo Ziyi returned to Shuofang and increased the number of elite soldiers. On the fifth day of the first month, he led the army to attack Vazhou.

On the 15th of Wuchen, Li You, the king of Wu, repelled the rebel general Xie Yuantong, and Xuanzong appointed him as the envoy of Chen Liutaishou and Henan Jiedu.

On the 29th, Xuanzong appointed Li Guangbi, the envoy of Hedong Jiedu, as the envoy of Fanyang Changshi and Hebei Jiedu. Yan Zhenqing was also crowned as the Hebei interview envoy. Yan Zhenqing then appointed Zhang Tang as an envoy.

At the beginning, there was a Qinghe man Li Cao, who was in his twenties, on behalf of the people of Qinghe County, to borrow troops from Yan Zhenqing, and said to Yan Zhenqing: "You are righteous and awe-inspiring, first call on everyone to resist the rebels, and the counties in Hebei regard you as the Great Wall of the country." Now Qinghe is your neighboring county to the west, and the state usually accumulates money and cloth in the Jiang, Huai and Henan regions there to support the army in the north, and is known as the 'warehouse of the north of the world'. Now there are more than 3 million horses of cloth, more than 800,000 horses of silk, more than 300,000 pieces of money, and more than 300,000 pieces of grain. In the past, when the Turkic Mosi Khan was conquered, all the weapons were stored in the arsenal of Qinghe County, and now there are more than 500,000 pieces. Qinghe County has 70,000 households and a population of more than 100,000. I have calculated that its possessions are worth three plains counties, and its soldiers and horses are worth two plains counties. If you can really lend troops to Qinghe County and control this area, with the Plains and Qinghe County as the core force, then the other surrounding states and counties will obey your command like human limbs. ”

Yan Zhenqing said: "The soldiers of Pingyuan County were gathered together just now, without any training, and they still feel that the troops are not enough, so they can take care of the neighboring counties!" But what if I grant your request? ”

Li Cao said: "Qinghe County sent me to borrow troops from you, not because of the lack of troops and to borrow your troops to fight a bloody battle with the rebels, but just to take a look at the elegance of your wise man. Now that you have not made up your mind, how dare I recklessly say what I want to do next! ”

Yan Zhenqing was very surprised when he heard this, so he wanted to borrow troops with him. But other people thought that Li Cao was young and vigorous, and he didn't see the strength of the rebels, and he could only disperse his troops by borrowing troops, and he would achieve nothing, so Yan Zhenqing had no choice but to refuse.

After Li Cao stayed in the pavilion, he wrote a letter to Yan Zhenqing, pointing out: "Qinghe County broke away from the rebels, returned to the imperial court, and donated food, cloth and weapons to help the officials and soldiers, but you not only refused to accept it, but also had doubts. After I go back and resume my life, Qinghe County cannot exist in isolation, it must be relied on, if you throw yourself into the rebels, you will become a strong enemy to the west, can you not regret it at that time? ”

Yan Zhenqing was shocked, and immediately went to the pavilion to see Li Cao, and promised to borrow 6,000 soldiers, send them to the border, shake hands and say goodbye. At this time, Yan Zhenqing asked again: "The soldiers lent have already set off, can you tell me your next plan?" ”

Li Cao said: "I heard that the imperial court sent Cheng Qianli to lead 100,000 elite soldiers out of Koukou to crusade against the rebels, but they were blocked by the rebels who occupied the dangerous terrain and could not advance. Now he should first lead his troops to attack Wei County, seize Yuan Zhitai, the Taishou appointed by An Lushan, restore the original position of Taishou Sima Chui, let him be the chief general of the southwest, and allocate a part of his troops to open the Koukou, let Cheng Qianli's army come out, and jointly crusade against the counties north of Ji County and Ye County until Youling was occupied by rebels. Pingyuan and Qinghe two counties led other allied county soldiers, combined with 100,000 troops, to the south to Linmengjin, and then divided troops along the Yellow River to occupy strategic points, control the rebels' retreat to the north. It is estimated that the army of the official army in the east is not less than 200,000, and the army of the western expedition in Henan region loyal to the imperial court is not less than 100,000. As long as you ask the imperial court to hold on, don't go to war lightly. In this way, it will not take more than a month, and civil strife will inevitably break out among the rebels. ”
