No if the hobbit companion is discarded the minion wins the skirmish.
...
If a skirmish has started and one side of that skirmish vanishes for whatever reason, the other side defaulty wins.
Ok thanks a lot, but are you actually sure about this??
I thought discarding companions while skirmish cancelled the skirmish.. that's the hobbit way
If a companion dies, though, it may be different.
I have been playing oddly, unfair to dunlands then, because I have never activated their "winning skirmishes habilites" like: stacking, controlling site, becoming fierce, dropping off yet another dunland,.. when a hobbit is discarded.
