Battle of Tianmenling: the confrontation between Khitan and sumo.

Since the Northern and Southern Dynasties, a large number of Mohong tribes have moved into the mainland, especially Youzhou and Lulong. According to the Customs of Northern Tibet, during the reign of Emperor Kai of Sui Dynasty, there was a war between Su Mo and Koguryo, and Su Mo was defeated. In order to avoid the military disaster in Koguryo, the Tusi made a sudden expedition and led nearly 20,000 people from Yalai, Kuletu, Yuejimeng, Yuyue, Buhulai, Puxi and Bukuli to abandon Fuyu City (now Jilin City, Jilin Province) and move to Liucheng, western Liaoning Province (now southeast of Ningfu New City, Liaoning Province). In the early Tang Dynasty, during the Wude period, Su Mo and Wu Su moved to Shenzhou (now Jianchang, Liaoning) in western Liaoning. In 628, another part of the Su Mo Tomb was moved to Lizhou (now Funing, Hebei) in western Liaoning. After the demise of Koguryo in the Tang Dynasty, forced migration was carried out, so Sogdian and Baishan, which surrendered to Koguryo in large quantities, were driven to Yingzhou area, and the Bohai Stone was among them. By about 696 AD, the population east of Youzhou and west of Liaohe River had reached more than 60,000.

In the autumn of 696, the Yingzhou Rebellion broke out, claiming to be the highest Khan, and repeatedly defeating Tang's army, which made him famous for a while. All ministries and Koguryo believers living in western Liaoning naturally have to submit to Li and obey his command. At that time, Yingzhou was a big chief, begging for assistance, begging for assistance, leading the troops to surrender to the rebels, and Li Zhongxin sealed it. Begging for the second phase is a relic (official in Qidan). A year later, Sun Wanrong was defeated, and Tang Jun gradually recovered the lost land in Hebei, Luanhe and Liaohe. At the same time, people who had participated in the rebel army or had been implicated in Li Sunyou were regarded as "the remnants of the rebel army" and counterattacked and liquidated. In order to avoid disaster, Daxie Zhongxiang and Daxie Zhongxiang had to plead guilty to Tang Ting again, hoping to be forgiven. Wu Zetian accepted the emperor's suggestion of appeasement, temporarily calmed down the situation, so as to buy people's hearts, and lied to forgive their people's innocence, which shocked the whole country and made the Qi Zhongxiang family Xu Guogong. However, the good times did not last long. When the situation stabilized, the fierce images of the Tang Dynasty appeared. General Wu, who was in charge of the counterattack, and others killed the Qidan army that laid down their weapons. "They all think this is against it, and they have taken courage from it." . In 697, Li Jiegu, a Khitan general who descended to the Tang Dynasty in the Mid-Autumn Festival, begged Wu Zetian to clear the Mohong tribe that had belonged to the rebels. Wu Zetian was overjoyed and wanted to "give him an official title and entrust him with his characteristics." Li Jiegu, who was cruel by nature, lived up to his sacred life. In less than a month, he defeated Kisby Feather, and more than 10,000 of his men were burned to death. Whether women and children were "slaughtered" by Tang Jun or not, Sheikh Kisby Faisal was tortured to death by the year after being captured by Tang Jun, and his head was sacrificed to Tang Ting.

After eliminating Qi Shibi's feather, Tang Ting aimed the butcher's knife at the next target-Qi Zhongyang. More seriously, however, the old chief begged and died in this crisis. At the time of crisis, Rong Ruo, the son of the old chief who turned to Zhong Xiang for help, was ordered by the Ministry and resolutely accepted this burden. At that time, Li Jiegu's crusade army arrived in Ruluo City (now the old military fortress in Liaoning Province), and the situation was extremely critical. As a young commander in chief, Ji Zuo Rong really lived up to expectations. He assessed the situation and thought that it was impossible to surrender to Tang Ting after the intention of destroying the whole country was determined. Although the northern Turks seem to support it, in fact they have no good intentions. At this time, they should not have any illusions about both sides. However, my hometown in Northeast China lost its strong enemy because of the new destruction of Koguryo, and the forces of the Tang Dynasty and the Turks were beyond my reach there. So he made a decisive decision, led his people, Koguryo adherents and their families with more than 20,000 people. In the late autumn of 697 AD, he secretly left the northern boundary of Yingzhou and went east to the hometown of Sumo Department.

At that time, there were three main roads for Rongbu to flee eastward: one was to take Xiangping South Road through Ruluocheng and cross Liaohe River to Liaodong County (now Liaoyang City, Liaoning Province); Second, cross huaiyuan town (now Beizhen, Liaoning Province) and take Xiangping North Road to the domestic city (now Ji 'an, Jilin Province) as the middle road; Third, cross the Liaohe River through Dingtong Town (now north of Xinmin, Liaoning Province), and then turn southeast to Xincheng (now Fushun North, Liaoning Province) as North Road. You Rong, who is famous for his "good use of soldiers", didn't choose three roads. The reason is that Ruluocheng is in the direction of pursuers, and Pei Xuangui, commander-in-chief of Anton in the Tang Dynasty, controls the domestic middle road, and Liaodong City in the Tang Dynasty is also under the control of Gao Qiushun. In order to get rid of Tang Jun's pursuit as soon as possible, Rong Ruo led troops to attack Tang Jun by surprise. At night, I crossed the Mangniu River to Tianmenling in the northeast of Yingzhou (now Ruerhu Mountain in the northwest of Fuxin City, Liaoning Province) and crossed the Liaohe River in the north of Kangpingkou, Liaoning Province. This road seems to be circuitous, but it does help to hide your whereabouts under the cover of mountains. Tang Jun, the solid department who came to pursue, just arrived at the east bank of Daling River. After many twists and turns, he found out the whereabouts of Rong Ruo. So it pursued for five days in a row, and finally in Jincheng (now Majiazhai Mountain City in the southeast of Kaiyuan, Liaoning Province), it caught up with the escaped Rong Ruo clan and quickly defeated the team left by Rong Ruo.

Rong people were shocked when they heard that the soldiers had arrived, and the old, weak, women and children wept bitterly. Seeing this, You Rong was unable to return to heaven. He urgently discussed with his subordinates and asked the local Koguryo survivors to help escort his family to Yen Jin Cheng for temporary shelter. He led everyone to prepare a sword and vowed to fight to the death with Tang Jun. While Kai Lee's strong army has not yet arrived, Rong Ruo has chosen the terrain around the performance city and quickly prepared for the battle arrangement. He also cut down trees as fences and laid them in a fan-shaped array according to the favorable terrain on the south slope of the mountain for the enemy. He also ordered two thousand troops to ambush in the hilly forest on the east bank of Shahe River in the south of the city. He personally led three hundred people to ride the waterfront Shahe River to cross the road and make a frontal army to meet Li Jiegu. Everything was ready, and in the afternoon, there was smoke and dust in the southwest, and the punitive army sent by Tang Ting swarmed in. Li Jiegu, the leader of Tang Jun, has always been famous for his bravery. History records that he "flew into the flock and was invincible." When he heard that Rong Ruo was fighting in person on the other side of Shahe River, he was already impatient with the hatred of repeatedly beating the air. He smiled and said, "What can I do with him?" So he ordered the whole army to head for Shahe, so as to annihilate all the fleeing enemies and capture Rong Ruo alive. See, approaching step by step, Rong Ruo immediately stopped, his three hundred soldiers saw the commander as cool as a cucumber, confidence doubled, and fear disappeared. When the ferocious enemy crossed the river and appeared in front of him, Rong Ruo waved his knife and pointed down, ready to throw himself into another battle and lead the riders to the enemy. Tang Jun, who just landed, thought he could slaughter again. He didn't expect the escaped "prey" to dare to resist, so he was caught off guard and really got a head-on blow from Rong Ruo. Li Jiegu, who was behind the house, was furious when he saw that the striker was killed stagger. He is worried that Zhong Jun cavalry will only take away the glory from their heads. You Rong saw that the trick of luring the enemy to pursue played a role. Without winning the battle, he ordered all his men to retreat and retreat. Li Jiegu, who is both wise and brave, sees this situation and is willing to give it a try. He immediately urged the horse to catch up until he reached the foot of Yanjing City. Although the semi-ring of Zhoushan in Yanjin City is not high, it is horseshoe-shaped, because the southeast is flat, the terrain rises with the slope and the road gradually becomes steep. Once the cavalry rushed here, it would naturally slow down because of the limitation of the terrain, and the left and right bumps would not form. Rong Ruo has a small number of cavalry. After climbing the hill, they quickly divided into groups and retreated behind the hedge. When Li Jiegu's cavalry brigade rushed to the front of the mountain, its vanguard troops were blocked by the rugged hillside for a while, and then the motorcade was huddled together because of Mercedes-Benz. People say that Ma Si's orders can't be conveyed at all. At this point, the hammer gunners who were pre-arranged by Rong Ruo behind the wooden fence were all in the air. As soon as they heard the call, they were in full swing, and the Tang Jun cavalry under the slope was not hit, and they immediately fell into chaos. When you Rong saw that the fighter plane had arrived, he immediately turned back to the horse's head and shouted, "It is unforgivable to kill the enemy." He led the army into the enemy's line for the second time. His subordinates all know that his wife and children are behind, the enemy is in front, and there is no way to escape, so they are brave and unusual regardless of personal life and death. Under the guidance of Yourong, all the soldiers who guarded Jincheng went into battle. They were condescending and hit Tang Jun hard according to the terrain. Seeing that the situation was unfavorable, Li Jiegu threw the two-wing cavalry out of the war circle and urged the rear infantry to cross the Shahe River quickly in order to reinforce. But what Li Jiegu never expected was that his move was exactly what Rong had planned. In the middle of the Tang Jun infantry crossing the river, the ambush hidden in the forest on the east bank of the river suddenly rushed out of the forest according to Rong Ruo's plan and took the Tang Jun infantry crossing the river. Among them, hundreds of Koguryo soldiers rode horses, armed with spears, and split the Tang army array in half with a red blade. At that time, countless people drowned in the water and fled without armour. Li Jie firmly led the former army in a fierce battle. Suddenly, he heard ShaSheng behind him and urged the horse to return to patrol, only to know that the latter army had been attacked and dispersed. To his great surprise, China woke up from a rude awakening and realized that he had been ambushed by Rong Ruo. Two thousand ambushes were killed soon, and Rong became more calm when he knew that the plan had been completed. He commanded his men to attack the enemy from front to back in order to destroy the enemy and win the final victory. A few hours later, Tang Jun was powerless, with more than half of the casualties. By the end of the war, Tang Jun's whole array had collapsed, the generals and animals were scattered, and the rest of the ranks fled for their lives. When coach Li Jiegu saw this, he knew that the tide was gone and had to change his flag to a horse. Fortunately, it was dark and hidden. He broke through to the west for more than 100 relatives and ran away. When he returned to Yingzhou a few days later, he was already "just back".
