The ability to request a castle or town's surrender while significantly outnumbered is a substantial improvement over native. The path to conquering Calradia leads to many repetitive battles and auto-resolve leaves much to be desired.
It would be great to see this feature extend to other battles. It sort of defeats the purpose of the character saying "Surrender or Die" to an enemy lord that is completely incapable or either surrendering or dying. Then to top if off, an enemy lord will sometimes say something like This:

^ There is a typo here btw.
I would like to see enemy warbands given the option to surrender without a fight much like castles and towns can now. Optimally this would factor in the characters persuasion skill, enemy party type and the amount they are outnumbered by. For instance: An enemy caravan might have a 60% chance of surrender, while a group of mountain bandits might only have a 30% chance. An enemy party may have a 50% chance to surrender when outnumbered 2 to 1, and a 70% chance to surrender if outnumbered 3 to 1. Additionally, honorable lords (not wanting to see their men slaughtered) might have a better chance of surrender than dishonorable ones (who don't care as much for the lives of their men).
Thanks for reading. I hope you will take this suggestion into consideration.
