@Bluestripe:

Trading treasure for creatures results in the same problem when you consider that no monetary system exists to give the treasure value, and thus that it makes no sense for trasure to be used as a recruitment tool.

Speaking of which...if Rakkety Tam was a mercenary, for what did he fight? Mercenaries fight for money - but there IS no money in Redwall. Perhaps I should add that to the list, unless someone else has something to note (I haven't read the book and can't say)...
