In "Wolf Totem", Chen Jin, a young man in Beijing, lies in a snow nest and follows the Mongolian father Bilig to admire the wolf pack's method of annihilating the yellow sheep. Chen Zhen originally thought that three wolves could deal with a yellow sheep, but to his surprise, dozens of wolves actually carried out a successful encirclement and suppression of thousands of yellow sheep, which made Chen Zhen stunned, and then Father Billig told Chen Zhen about a Mongolian iron horse, using this tactic learned from the wolves, annihilated the 150,000 elite battles of the Jin Dynasty with 30,000 troops, which is the famous "Battle of Sanfeng Mountain" in history.
The Battle of Sanfengshan was a battle between the Mongol Iron Horse and the Jin Dynasty that decided the fate of the two countries, and since then, the Jin army that has been dominant for a hundred years has not only lost its elite, but also lost the two commanders of The Completed Yan Heda and the Qianla Pu'a, as well as a number of famous generals such as the Completed Yan Chen Monk, at this point, the Jin Dynasty is already crumbling and not far from collapse.
Since the founding emperor of the Jin Dynasty established the Jin Dynasty, it has invaded the Northern Song Dynasty and the Southern Song Dynasty for many years, which has caused the Jin Dynasty, which is not dominant in population, and has consumed a lot of strength in the war. At this time, the Mongols rose rapidly behind it, and under the leadership of Genghis Khan, who was "a generation of heavenly pride", they first unified the Mongolian steppe, and then drove the Jin people who had risen in the northeast out of their hometown in the northeast, forcing them to move from Yanjing to the capital of Bieliang (present-day Kaifeng, Henan) and retreat to the Central Plains. At this time, the Jin Dynasty had the Southern Song Dynasty in the south and the Mongol Iron Horse in the north, and it was already attacked by the enemy on its belly and back, so the powerful Mongol cavalry launched an all-out attack on the Jin Army. The Battle of The Three Peaks took place in this context.
In 1232, the Mongol Great Khan Genghis Khan ordered his youngest son Tuolei to lead his troops around the Jin Dynasty's military stronghold of Tongguan, cross the Qin Mountains, and in the Hanzhong Basin, take a big detour to the south of the Jin Dynasty, and then lead the army directly to the capital of the Jin Dynasty, Beijing. The famous Jin dynasty general Guanyan Heda led 150,000 Jin troops to intercept, so the two sides fought a major battle in the Sanfengshan area (southwest of Yuzhou, Henan). The Mongol army under the command of Torre was inferior in strength, so it adopted the tactic of fatigue of the Golden Soldiers, when the Golden Soldiers attacked, the Mongol army retreated without a fight, and when the Golden Soldiers had just settled in the camp, the Mongolian Army came to sneak attack. As a result, the Jin soldiers could not rest day and night, and all the grain and grass were burned by the Mongol army in the sneak attack, so that the Jin soldiers ran out of food for three days, and when Wokoutai led another Mongol cavalry to rendezvous with Torre, they finally surrounded the 150,000 troops of the Jin Dynasty on The Three Peaks Mountain.
At that time, it was snowing heavily and the climate was very cold, and the Mongol army was cooking meat on all sides and taking turns to rest. However, the golden soldiers could only stand frozen in the snow in their armor, hungry and cold. The Mongolian army knew that the Jin soldiers were eager to break through, so they deliberately gave way to a road. When the Golden Soldiers scrambled to flee for their lives, the Mongolian army ambushed the troops, and 150,000 elite Golden Soldiers were almost completely overwhelmed by the heavy snow that was waist-deep. The completed Yan Heda and the completed Yan Chen monk led the remnants of the Jin army to retreat to the city of Junzhou, and the Junzhou was immediately attacked by the Mongol army, and the completed Yan Heda was killed in battle, and the completed Yan Chen monk did not want to die in obscurity in the rebellion, he personally came to the enemy camp to ask for death, and finally was killed because he refused to surrender. He fled to Fenjing and was captured by the Mongol cavalry, who was also killed for refusing to surrender. In this battle, the last main force of the Jin Dynasty was annihilated, and many generals were lost, "the soldiers are no longer revived", and the fall of the country is inevitable.
In September 1233, the Mongol army entered the city of Caizhou, where Emperor Jin had fled. In October, the Southern Song Dynasty also led the famous general Meng Jue as the main commander, led an army of 20,000 Southern Song Troops, transported 300,000 stones of grain, fulfilled the contract with the Mongol army to attack Caizhou, and in November the Song army arrived in the south of Caizhou City, Meng Jue and the Mongolian general Tacha'er agreed on the boundary of the siege between the two sides, agreed not to invade each other, and at the same time cooperate with each other to attack the city. The Jin army stubbornly defended the city for three months, and finally it was difficult to support it because there was no food and grass inside and no rescue troops outside.
On the tenth day of the first month of 1234, the Mongol army attacked the western city, the Song army broke through the south gate, the Jin Emperor saw that the general situation had gone, and the legend of the Emperor Canghuang was hanged after the last emperor Finish yan Chenglin, and the remnants of the Jin army were either killed in battle or committed suicide, but none of them surrendered, and Yan Chenglin was also killed by the rebel army. The Jin Dynasty has always been known for its martial prowess since the founding of the People's Republic of Yan in 1115, but after 119 years of history, it has finally perished.
The "Battle of Sanfeng Mountain" is a typical example of a pursuit and annihilation war in the history of Chinese warfare; under the situation in which the troops were inferior, Tuolei took the enemy to advance and retreat, the enemy retreated and disturbed, used tracking and attacking to contain the tired Jin army, and then adopted the tactics of encircling the Three Que and one, taking advantage of the time and geography, and finally annihilating the elite jin army with inferior troops. It is said that the Mongol army used this tactic against the heavily armored cavalry of Europe during several western expeditions, and the three major european knights were defeated by the Mongols, and this tactic of the Mongols was inspired by the tactics of the wolves on the steppe to encircle and suppress their prey.
