... okay. your missing the point of the battle. and ignoring the intent of my orders. which was to make the war Last only this turn. not an un-realistic multi-century conflict. there CANNOT be a stalemate because of that battle. the political and military realities prevent it.
If I took the city and kill the emperor, then unless the majority of their army is completely insane, I win. Outright. I have a legitimate claim on the throne. I have supporters withing the army and nobles. I have proven that their emperors god-cult is a complete folly, having been struck down mere months after he made the claim. the emperors former family is a complete disgrace and demonstrably weaker then Trmil's family.
if they had troops in the area to drive me out while I was attacking, then they are eather compleatly incompetent (thus I win), or I should have been destroyed upon landing.
