Then there are Longbows on a hill city with a couple of City Garrison promotions. Even modern units can have a problem with those.

Nuke them from orbit. It's the only way to be sure.

Or use a spy to cause revolt and your catapults/ trebuchets to soften the defenders

Lord Avalon,
That's a bad idea. If they have survived that long, you want to vassalage them and use them for your national olympic archery team
