 Southern Tang forces attempted to use flamethrowers against the Song navy, but were accidentally consumed by their own fire when violent winds swept in their direction.Documented also in later Chinese publications, illustrations and descriptions of mobile flamethrowers on four-wheel push carts appear in the "Wujing Zongyao", written in 1044 AD (its illustration redrawn in 1601 as well).It has been suggested that the flamethrower reached China from the Tamil dynasties of India with which they traded.
