Things changed in the late 1700s, when the Mysore Kingdom of southern India went to war with the British East India Company. Mysoreans packed iron tubes with combustibles, creating more thrust than the lightweight bamboo fire arrows of yore. These new rockets could travel up to one thousand yards. More importantly, Mysoreans realized rocket warfare was most effective when launches happened en masse. In one battle, some 2,000 rockets rained down simultaneously. And no doubt soiling some British trousers. But, the British won. And confiscated the Mysorean rockets.
