I've had many siege towers destroyed by the AI, about half to archers using fire arrows and half to towers using fire arrows. For some reason, they only seem to nail a tower when it's a closely contested siege. Whenever I have overwhelming force, I never lose a tower. Makes for a fun game when my pincer attack on the gate walls fails due to a cohort bonfire.
