The Song Dynasty had a large number of soldiers but weak combat strength Invented 3 amazing weapons are still in use today

Although the national combat strength was not stronger than that of the Tang Dynasty, it invented many powerful weapons. (Schematic)

The Song Dynasty was heavy on literature and light on martial arts, always giving the impression of humanity and courtesy, and its combat strength was not as good as other dynasties, but in ancient times when wars were frequent, the Song Dynasty adopted a defensive strategy to the outside world and carried out weapons research and development on a large scale, when firearms technology was quite perfect, making cannons, mines and grenades, etc., and it was the first rocket weapon used on the battlefield in human history.

In the first year of Jing Kang (1126), the Jin people besieged the capital of the Northern Song Dynasty, Fenjing, the chancellor Li Gang, when defending the city, used thunderbolt cannons to repel the Jin soldiers, and made great achievements, "Jing Kang's Letter Record" records that "the thunderbolt cannon was fired at night to hit the thief, and the army exclaimed", which shows that its power is quite amazing, and the thunderbolt cannon is also known as "gunpowder fireball", that is, the so-called cannon, the sound is like a thunderbolt, so it is named, and projected by the trebuchet.

In 1130 AD, the fourth year of the Southern Song Dynasty Gaozong Jianyan, when the Jin State attacked Shaanzhou, the Song soldiers buried the gunpowder cannon in the ground, if the Jin soldier stepped on the organ, the gunpowder cannon would automatically detonate, similar to the concept of mines, the lethality should not be underestimated, in the 14th century book "Fire Dragon Classic", there is also a description of landmines, in 1277 by the Song and Mongols in the war widely used, gunpowder cannon was improved in the Yuan Dynasty.

In 1189 AD, the sixteenth year of the Southern Song Dynasty Chunxi, there were already grenades, according to the Jin Dynasty literary scholar Yuan Haowen recorded in the "Continuation of Yi Jianzhi", referring to the Jin Shizong period, Shanxi Yangqu North Zheng Village there was a hunter "Tie Li", by catching foxes for a living, one day in the last year of Dading, he found that there were fox nests in the ancient tomb, so he used clay pots filled with gunpowder to ignite the fuse to detonate the trap, and the clay pot gunpowder in Tie Li's hand was actually the prototype of the grenade, and now it has become an important role in the history of world weapons.
