According to historical data, in order to cut the grass and root out the king of the flower thorn model country, Genghis Khan brought the Mongol army to the north coast of India. Genghis Khan also took the opportunity to attack the country around him and was very wealthy. He ordered his soldiers to cross the Indus River and march south to appease India. However, the Mongol army, which had just crossed the river, did not invade India, but hastily retreated to the area of present-day Afghanistan. Why?
According to the Records of the Yuan Dynasty, when Genghis Khan's army crossed the Indus River, the soldiers were very tired and thirsty, so they got off their horses one by one to rest and prepare to go to the river to quench their thirst. Suddenly, the river boiled like boiling water, rolling violently. A few seconds later, with a loud roar, a huge monster suddenly jumped up from the river. One by one, the soldiers shot arrows at the monsters. The monster in the middle roared again, listening carefully as if he were saying: Lord Ru has already returned.
Returning to God, the Mongol master Yelü Chucai relayed to Genghis Khan that this beast was a divine beast that was a messenger from heaven, warning us not to go any further. Therefore, Genghis Khan obeyed the will of heaven and ordered his soldiers to stop advancing.
For this historical record, historians say that the beast is a mythical animal in Chinese mythology. It resembles a unicorn, with strange shapes and great magic. It can travel 18,000 miles a day and speaks four languages. But after all, myths and legends are like that. At that time, the real situation should be: Mongol soldiers came out of foreign India. After all, Mongolia and India are geographically different. The soldiers saw animals they had never seen before and misinterpreted them as some sort of monster. And listen to the monsters' cries for early return! It should be that Yelü Chucai played an important role in persuading Genghis Khan to return to Korea, so why did this Yelü Chucai borrow the topic to play?
As the military division of the Mongol army, Yelü Chucai must have been very talented. At that time, he analyzed that if the Mongols conquered India, the probability was very low, because there were two difficulties that were difficult to overcome, one was that the climate differences in different geographical locations were too large, and the other was that the Indian war elephants, although in numbers could not be compared with the Mongol iron horse, were also quite strong.
First of all, the climate, the mongol soldiers' cavalry had good shooting skills, and the ability to attack on horseback. This feature is that they are invincible on the plains, but they do not have much advantage in the area of too many mountains and rivers, only India is such a geographical environment, and india's climate is hot and humid, and the Mongolian people are particularly afraid of this hot and humid environment in the Mongolian plateau and the arid regions of Siberia.
Speaking of Indian elephants, as early as the 3rd century BC, the Indian Peacock Dynasty used elephants for military warfare. Elephants have the advantage of height, size, and strength, and they are infinitely powerful. Indian troops can erect towers on war elephants and attack them from above. Genghis Khan had no advantage in this or the other, so the military division took advantage of the problem to let him withdraw.
