The Brits were a little sore over those rockets from India

Explanation: During the Second Anglo-Mysore War in India, British forces faced innovative rocket technology which caused them significant losses.

The four(!!!) Anglo-Mysore Wars would, however, eventually result in the defeat of the Kingdom of Mysore, due in no small part to British diplomacy isolating Mysore and leveraging neighboring kingdoms of India to contribute to British war efforts against Mysore.

The Brits would later use the technology they encountered in Mysore in their own rocket artillery during the Napoleonic Wars.
