Song military engineers found gunpowder to be helpful in siege warfare, leading to the development of early types of rockets, cannons, bombs, and mines.
The Wujing zongyao (“Collection of the Most Important Military Techniques”), a military manual from 1044 CE, records the first true gunpowder formula and describes how to produce it on a large scale. Gunpowder was first use in warfare as an incendiary, or fire-producing, compound. Small packages of gunpowder wrapped in paper or bamboo were attached to arrows and lit with a fuse.
Bombs of gunpowder mixed with scrap iron would be launched with catapults. Another use was “fire-spurting lances,” which were a kind of flame-thrower using bamboo or metal tubes for their barrels.
Weapons involving gunpowder were extensively used by both the Chinese and the Mongol forces in the 13th century. Song efforts to continually improve their weapons were one reason they were able to hold off the Mongols for several decades. But the Mongols, like the Khitans and Jurchens before them (who conquered the first, or northern, Song dynasty capital in Kaifeng), were equally ready to adopt new and better military technology, often by capturing the Chinese engineers and gunners.
