This question isn't related to Buatha's question, but I'm a beginner so I thought this place was appropriate.

An independent province separates me from my enemy and I planned to take it, but I've failed a couple of times already. The independents have assorted barbarian units and knights that probably came from random events, they number about 100 or so.

The biggest problem is a priest commander there that has Soul Contract? item in his possession. I don't know if it's a random event or if the priest is a reminder from a defeated pretender, but there are hundreds of devils in the province, probably about 400 or so. They just fly to my troops and tear away most of it on the first turn. My army routs or just gets decimated. I'm new so I don't know what to do. Devils keep making babies or something.
