Sorry, that I couldn't respond earlier to the vague number of slavers killed by Carl's archers. (I was near a computer very, very little over the weekend.) And I will be reading your post shortly Nogrod, so I don't know if what I'm saying now is at all relavant. But the archers might have killed as many or as few of the slavers as my fellow writers find convenient. But if they didn't kill many, they certainly wounded several of them.
The one confirmed dead slaver Carl was personally struggling with, would be Hamin, despatched courtesy of Kwell (with great thanks, I'm sure). And he was not from the grouping that charged the tunnel to my mind, but was with with one of the other two groupings.
