Aiming cannons takes time and you might get stabbed with a pitchfork if you just try to run up an light a village on fire with a torch. But you just HAVE to watch that quaint little town burn. What to do? Well, if you lived in the 1500s, you might have considered rocket cats.
The University of Pennsylvania just published a warfare manual from 1530 that suggests a good way to set a village alight is to capture a cat, attach a bomb to it's back and send it home.
