Nogrod,
You raise some good points. I do think there is a lot of scrub vegetation thick enough to provide some cover. But if you want to have some of the attackers or Alinarmi discovered, I certainly won't stop you!
The attackers would not have know all the ins and outs of you folk, including the scouts (much as mush brain Child managed to miss these points
). it is perfectly legitimate for someone to have nabbed one or more of our party.
Heck, if you (or someone else) wants to capture and question Alinarmi in this post or another, maybe you can get some information out of him (it won't be easy) that might be useful for the King of Rohan in combatting the hoarde of Easterlings and Orcs that are now pouring into his realm.
