Diaoyu City was built in 1243, although it was built on a mountain, but the city has a large area of heaven and earth and rich water sources, which is not only easy to defend and difficult to attack, but also can rely on the resources in the city for long-term perseverance. And diaoyu city did not live up to the expectations of the southern song dynasty soldiers and civilians, until the southern song dynasty fell Diaoyu city was not breached by the Mongol army.
In 1251, Möngke succeeded him as the Great Khan of the Mongols, and it can be said that he worked hard to continuously expand the territory of the Mongol Empire, destroy Dali, conquer Goryeo, and send Hulagu to start another western expedition. In the continuous conquest of the outside world, Meng Ge did not forget that there was also a Southern Song Dynasty at this time, and the Mongolian and Song Wars broke out again during Möngke's reign, and the two sides fought fiercely in many battlefields.
In 1258, Möngke sent a large army to attack the Southern Song Dynasty in three ways, this time Möngke personally led the main Mongol army to attack Sichuan, and soon captured most of northern Sichuan, but Möngke would soon encounter blood in Sichuan, because he arrived at Diaoyu City on February 2, 1259.
Meng Ge first sent people to Diaoyu City to persuade the defenders to surrender Wang Jian, and Wang Jian, as a sign of his stubborn will, directly killed the Mongol emissaries who would surrender in the future. Meng Ge saw that Wang Jian's brothers were not on the road, so there was no nonsense, Meng Ge personally supervised the siege of the city, but the Diaoyu City was too strong, and because it was built on the mountain, the Mongols could not carry out the superiority of troops, and as a result, they attacked for several days in a row, and even the outer city of the Diaoyu City was not captured, but they suffered heavy casualties.
Meng Ge saw that the Diaoyu City was difficult, but because the Khan's face was unwilling to give up, he mobilized more troops to come to the confluence, and had to take the Diaoyu City. The Mongol army relied on the large number of people to attack for more than two months, both the Mongol army and the Southern Song defenders were killed and wounded very badly, but the Southern Song army and civilians hated the enemy and vowed not to surrender. On April 24, the Mongol army took advantage of the night to attack the outer wall of Diaoyu City, and the Southern Song army and the Mongol army engaged in a fierce battle on the outer city wall, and finally repelled the Mongol army's attack.
For several months, the Mongol army besieged Diaoyu City day and night, but the Mongol army had been under the fortified city for a long time, and had committed a military taboo. Natsumi advised Möngke to go around the city and continue to attack other places, because although Diaoyu City was difficult to capture, there were not many defenders of Diaoyu City and could not threaten the Mongol army in the wild. This was a very correct strategy, but at this time, the Mongol army had aroused the anger of the Mongol generals because of its successive defeats in Diaoyu City, and even Möngke had to take Diaoyu City, otherwise in Mongolia, which focused on military merit, his face as a great khan would not be able to hang.
However, at this time has reached the hot summer season, especially in Sichuan, the weather is hot, the Mongols are not adapted to this weather, coupled with the water and soil, heat stroke, etc., the Mongolian army died of illness and heat death, at this time Möngke is counting on relying on a long-term siege to break through the Diaoyu City, but as mentioned earlier, the Diaoyu City because of the grain fields and water sources, so Möngke's hope is doomed to fail, and even the Song army also specially threw two fish weighing 15 kilograms each and more than a hundred noodle cakes to the Mongolian military camp with a trebuchet. And also very provocatively wrote a letter, meaning: you will be around for another ten years, buddy will be able to stand up.
This Mongolia has no way, can not fight and fight, the siege can not be killed, and with the passage of time, the Mongol army itself can not hold on, and the most serious is the Great Khan of the Mongol Empire Möngke died in the army, the specific cause of death is still controversial, some people say that it is a disease death, some people say that it was smashed to death by the cannon stone of the Song army's stone thrower, but no matter which cause of death, Möngke's death can not avoid the three words "Fishing City". The Great Khan died under the Diaoyu City, and the Mongol army had no choice but to withdraw.
And Möngke's death also caused the division of the Mongol Empire, Kublai Khan and his troops went back to fight with Ali Buge for the Khan's throne, and Hulagu, who was on the western expedition, also withdrew his troops because of Möngke's death, it can be said that this small fishing city not only continued the life of the Southern Song Dynasty, but also indirectly saved half the world.
