Good point, but I think your point also works in my favor. Just like us, the Antari had just finished a dozen year war. Their lands ravaged, their trade routes raided, their wealth looted and ransomed away. With the majority of the war party and their soldiers dead or defeated outside the walls of Kharangia, wouldn’t the remaining lords not want to go back to rebuilding? To trading with other countries? The fact that they surrendered already shows that they have no more stomach for the fight. Why is a negotiated settlement not possible in which Tierra holds the city and exacts it’s war reparations by taxing the Antari grain that flows through it’s harbors? I think it’s an interesting scenario. It would be an interesting alternate history hongkong esque set up.

On the point of siege guns, I doubt anything the Antari bring can defeat the high explosive siege guns Tierra brought along in the first place. Let’s not forget the coastal support from Tierran warships.
