Does "Demand Surrender" ever work?

[Prussian to the Iron]

i've never had it surrender an engagement in the field either however - no matter how badly outnumbered or outclassed...

...............................theres a surrender option in field battles?

Here's a thought. Maybe the AI just won't ever surrender victory condition sites like they (usually) won't trade for them. The AI usually expands fairly terribly so I wonder if this has something to do with it.

but i dont think that helps us; playing world domination, which means they have only a few victory settlements, but they wont give up anything except for 1 settlement. ever.
