Before They Are Hanged Question- Spoilers

I am 25% through the book. I would have assumed by now that I would understand the overall dilemma or connection of the characters 5/12 of the way through a trilogy. Somehow, I am still entertained, but I have no idea what Logan, Jezal, Ferro, Bayaz, and company are doing. I just know they are heading west somewhere, and when someone asks where they are going, Bayaz gets pissed. Due to lack of context, I find their chapters to be a bit of a grind. However, Dogman and West chapters are interesting because I understand what they are trying to do. They are in a war with Bethod.

So, my question is, did I completely gloss over their purpose? if not, can anyone offer a non-spoiler indication of how much longer until the main purpose of the book is clear?
