Help on cossack quest

[Reapper45]

Unfortunatley the search function is down so I have no idea whether this has been asked.
How do i complete the cossack quest where you have to get the money from Dunayivtsi
on all of the options the village elder just calls me crazy.

Talk to every cossack lord and ask them about what richelieu said , ogniem i maziem (or something like that) and with fire and sword are not the right answer , it's this is the last argument of king , or something like that. maybe if you ask jacque he tell you .

Yeah the Cossacks get it wrong. It's the Muscavites that actually know their French history.
