Battles and wars aren't easy to write. Trust me. I have a lot of experience with this.
Yes, there's a little direct action at the beginning of the chapter, but Kyven isn't there to watch the battle at Durm in its entirety. When he's forced to retreat, that's it. What happens in the battle you'll find out in chapter 18.
