A situation just recently took place which exceeded all other AI suicides ;) I'm sure it was hard-coded AI that caused the tactical error. I (Lusotannans) was attacking a Carthie town in SE spain. Its garrisson was almost non-existant, but a very large force of citizen militia was rushing toward the town. Due to my spies, I was able to enter the town pretty easily, and overcame the garrison. I ended up defending the town from the reinforcements. ;) But a strange thing happened... as the carthie citizen militia tried to enter their own gate and defeat my own troops, the militia all but insta-routed - around 2,000 so or, I think. Instead of heading for the hills, they tried to retreat _through_ my men who were blocking the gate. I lost, I think, 8 men to their several thousand. While I know the Ai is probably hard-coded to try to retreat to the town center even when suicidal to do so, what surprised my was how incredibly easily this large milita routed when they hit my less numerous iberian milites inside the gate. Did I just get lucky, or are they really that cowardly that they can freak out at the drop of a hat? I suppose I'll be fighting them more often soon, and will probably figure it out soon. No wonder they lost the war against Rome. :p
