"Ashes' Will" - "The Last Soul" [2nd campaign, 1st mission]

I didn't even get a chance to start playing, and I'm already stuck:( Every time I visit the witch's hut, the red faction declares war on me. Their army is much larger than mine, and I have no chance. How did you guys get past it? What should I do about the red faction? Please don't just write "I breezed through it in 5 minutes." Something more helpful would be better. And please, be more detailed:smile45:
I guess I was just having a bad day yesterday. It was easy the second time around.
