In the Battle of Yashan, why did more than 100,000 people in the Southern Song Dynasty prefer to jump into the sea rather than fight a battle against the water? Although the Battle of Yashan was magnificent, it was highly praised from the perspective of national integrity.
But militarily it was a very failure. Lu Xiufu was simply incapable, and eventually buried hundreds of thousands of soldiers and civilians, as well as the Great Song Dynasty. Moreover, in the process of the emperor's escape, the Southern Song Dynasty was still fighting among the TM, which is really incomprehensible. The party struggle ran through the entire Southern Song Dynasty, or the entire Two Song Dynasties, and truly achieved the goal of not dying endlessly, never dying, until all of them were dead.

So I really don't know what to say. I always felt that I could not complain that Mongolia was too powerful, and it was completely the Southern Song Dynasty court itself that killed itself. All the capable generals were either killed by civilian officials or forced to surrender to the Mongols.
In the end, the civilian officials saw that there were no generals who could fight, preferring to go up and send them to death than hand over the army to capable military generals. Although the students are very dignified, the incompetence is a fact.
100,000 people is just an adjective, and the Yuan army saw the floating corpses on the surface of the water densely packed, and killed 100,000 enemies in order to falsely report the results of the battle. Zhang Shijie was afraid that conducting a naval battle would disperse the troops and would be eaten by the Yuan army in the case of a huge disparity in strength, so he concentrated all his forces to protect the little emperor.
Even if most of the ships of the Song army engaged in naval battles were river boats, fighting in the sea was shaking endlessly, the soldiers could not stand at all, and the soldiers were deeply troubled by seasickness, and they could only use iron locks to connect the ships, which was easy to be attacked by fire.
Secondly, Zhang Hongfan besieged the Song army and cut off water and food, in fact, before the final war, the Song army already had many wounded and weak soldiers who had died of thirst and starvation, and the soldiers who were lucky not to be thirsty and starved to death actually had no ability to resist.
Since the feudal dynasties of ancient times, the cultural inferiority of the emperor's grace and grace, relying on parents at home, relying on friends when going out, relying on heaven and earth, can not rely on themselves, otherwise it is not a feudal dynasty. The emperor gave him a piece of wiping paper, which was also to be framed. If the emperor is gone, it is equivalent to the sky falling, and the military and the people have no Lord, no heaven.
As long as the emperor is there, even if it is an eight-year-old doll, the main backbone of the people under the feudal is still there. When the emperor committed suicide by throwing himself into the sea with the eight-year-old emperor on his back, for 100,000 soldiers and civilians, following the emperor to martyrdom is the greatest integrity! However, it is understandable that feudal culture has been so many years, in exchange for that time, no matter who it is, it is the best way to preserve integrity and martyrdom at that time.
Backwater war is not to talk about, the word is wrong, backwater war is behind the water, there is no way back, the final fight. But it was a naval battle, and the ships were destroyed, and there were no conditions for a deadly war. To eat or not to eat, to drink or not to drink, (don't ask why not drink seawater).
Moreover, at that point, I think there are probably few real "people", most of whom are officials and family members who follow the emperor. If they did not commit suicide by throwing themselves into the sea, the remaining fate could be imagined, the men were plundered and killed, the women were insulted; throwing themselves into the sea and leaving their integrity was already a last resort and the best way for them at that time.
The culture of the emperor is not desirable, so the leader said that the people must stand up and be their own masters. It is this sentence that breaks the traditional "Lord" and breaks the traditional concept. Relying on the "Lord" of the Emperor's grace, man has no Backbone, and which "Lord" of the West depends on?
He would only say dead to take you to heaven and rely on the landlord? The people are still Yang Bailao. The Lords who need to be "relied on" are unreliable, and the best Lord, the truest Lord, is the backbone.
