There. I foolishly filled in a save during the wee hours of the morning. But what can I say? I was in the mood for writing- apparently I can only stay awake when everyone else is asleep...
Anyways, Shae has taken down one slaver near the trench. She's been injured from her fall off the horse- a gash in the forehead, a broken wrist, and a bruised rib, maybe cracked. It's nothing too serious, but it'll definitely slow her down. She's on her way to help the women and children as well, but since she's on horseback, she might end up beating the other men there.
I'm not sure what happened to the NPCs of the cavalry- Shae didn't really pay attention to them. If you haven't noticed, she can be a bit self-absorbed at times.

I'm sure some have done damage as well, several others were most likely killed. Most of them had little experience on horseback, and would have just as much trouble staying on their horses as Shae.
