That was rather a large lump, wasn't it? I'd already dowloaded (and expanded) the zip file, so was not unprepared, but it's big enough that I don't dare do one of my standard line edits, and not putting extra spaces between paragraphs will scare off a number of other potentially helpful people (it just looks to big to attempt. like that of the page. So I'll concentrate on weapons(particularly since punctuation seems pretty good).
Tall and imposing, wrapped in thick furs and leathers, and brandishing a longbow with arrow notched.
You can't "brandish" a longbow with the arrow on the string – in fact, you have difficulty brandishing something a hand longer than you are anyway. And a longbow is a clumsy weapon for mountain work; it's extra power and range are hardly useful in the sort of situation we find are hardly useful, and the inconvenience of scrambling round rocks with something that cumbersome (plus the need for firm footing from which to shoot – no hiding behind rocks or loosing from concealment) would make a lighter hunting bow a more practical choice.
The aim was true, and his throwing knife clattered into the bow. The tension the wood was under made it that much more delicate, and when the heavy blade hit it, the yew split down its length, snapping clean in half and causing the bowman to punch himself in the face.
Particularly if the knife "clattered“ rather than thumping into it seems strange that the wood would split across the grain; and even more peculiar that he would have confidence that it would do so, however much strain it was under. Would not cutting the string (a difficult shot, to be sure) have much the same effect (punching oneself in face and being left with a useless weapon)?
so when one saw a man in possession of a sword - especially a claymore like this - they knew that the wielder must be a man of standing.
A claymore is a long, double handed sword that would generally be slung across the back in a baldric, or along the flanks of a horse. It would not be sheathed at the waist, as it it longer than the leg of even a tall man.
and took the mountain man in the leg about halfway up the blade. The leverage wasn’t there to decapitate, but he felt something brake beneath his blade,
To "decapitate"is to cut the head off (Latin "caput", the head) To remove the head from the knee upward seems a bit excessive. Oh and it's "break", not "brake".
