In china's Song Dynasty, many firearms have been invented and applied to the military field. The use of firearms is recorded in both the Song Shi Military System and the General Outline of the Martial Arts. There are roughly explosive weapons, offensive weapons and prototypes of later guns.
Explosive weapons are more common and simple to manufacture. There are more fire offensive weapons, including rockets, fireballs, and fire tribulus, and the more famous ones are "fierce fire oil tanks". According to the General Outline of the Martial Arts. Volume 12 Shoucheng records: "The fierce fire oil is made of cooked copper as a cabinet, and the lower four legs are applied, the upper column is four rolls, and a huge cylinder is applied horizontally on the cylinder, all of which communicate with the cabinet... When placed, it is poured from the oil injection cabinet in the middle of the sharo... Infused with gunpowder in the middle ... Everyone in the middle is eroded, and the water cannot be extinguished. ”
Muskets were later built. On this basis, the prototype of modern firearms was created, the "assault rifle." "Fire bullets while shooting out flames.
It is reasonable to say that the firearms of the Song Dynasty were at the leading level in the world and should be able to suppress the Jin Dynasty. But this is not the case. Sadly, the Jin Dynasty paid much more attention to firearms than the Song Dynasty. They soon absorbed the advanced technology of the Song Dynasty and developed their own firearms that were not inferior to those of the Song Dynasty.
The emblematic firearms here are the Thunderbolts. History of Jin. In the biography of ChiYan Hexi, it is written: "The one who defended the city with the name of the artillery 'Earthquake Heavenly Thunder', the iron can contained medicine, lit it with fire, and the cannon was fired, and its sound was like thunder, smelling hundreds of miles away, and the fire was half an acre above, and the fire was lit with armor and iron."
In this way, there is not much difference in the level of firearms between the two sides. Since firearms were still in the initial stages at that time, and the song and Jin dynasties could not open the distance, firearms could not determine the victory or defeat of the battlefield.
On the battlefield, the armored heavy cavalry of the Jin Dynasty ruled the battlefield, and the Song Dynasty lacked warhorses and was not at all an opponent of the Jin Dynasty cavalry. Therefore, the Song Dynasty, which could not win the field war, had difficulty winning the war.
Coupled with the fact that the Song Dynasty monarchs and vassals were meticulous and stealing peace, there was no belief in the Northern Expedition to restore their homeland. All this makes the government and the opposition up and down, lifeless, without a little anger.
The national policy of "emphasizing literature over military force and suppressing military force with literature" when the Song Dynasty was founded also made the Song Dynasty army the most unenterprising force at that time. Its generals could only fight according to the plan of death prescribed by their superiors. How could this possibly win the Jin Dynasty?
Therefore, it is people who play a decisive role in war, and relying solely on a few new weapons, and the weapons that the other side will soon have, cannot determine the outcome of the war. This is why the Song Dynasty, even if it was advanced in firearms, was not an opponent of the Jin Dynasty.
