My 82 years old king of a small kingdom got invaded by 8 years old nord king upstart.
I managed to defeat invader, killed all his troops, and "took over" all of his counties in the sense that I defeated defenders of every holding. All counties are now stripe-colored, and holdings have "under new administration icon".... except I can't have those counties.
If I "offer peace" there is no option take over counties or get any land. His casus belli was contesting one of my counties. He lost, so he didn't get it.
So... what now? Can I grab a bit of his land as a punishment for attacking me, or should I just end the war to cut the expenses? I don't see any option to actually get any land.
Or if I keep the war going for 10 years (I control everything, so he doesn't even spawn troops now) so the "under new administration" icon hopefully disappears, do I get those lands?
Advice?
