I wonder if anybody have the exact inormation about barrelled small fire-arms in Song-Yuan periods. Once Thomas Chen mentioned that "kuaiqiang" was widely spread in China in the end of Yuan. but he is like a ghost
In the end of Yuan the gunpowder technology was transferred to Korea by former Yuan minister and already in 1410-s Koreans have a division of 5000 men with barrelled fire-arms called "chongtong" or "qiangtong" in Chinese. That weapon fired small arrows and was used by soldiers in the 2 row in the linear batle formation (the 1 row was of shield-bearers).
What's about the situation with the similar weapon in Song-Yuan (probably early Ming) in China?
Can anybody help me in respect of exact datas, facts, links, images etc.?
Best regards,
Alexey.
