City Walls

[DaciaJC]

I always find that defending a city with a large stone wall is much easier than defending one with wooden walls - you have an extreme height advantage where archers, slingers, and skirmishers can devastate enemy units, and there are multiple towers firing a limitless supply of arrows (unrealistic to say the least, but there's no way around it) to those on the ground. And since enemy units using siege towers or ladders will attack you individually or in pairs, you will always have local numerical superiority to crush them.

Perversely, though, I find that defending a city with huge stone walls is more difficult than one with simply a large stone wall or the Celtic wall - the siege towers fire ballistas, which can thin out your troops on the wall very quickly.
