The fighting Uruk-hai

[eXistenZ]

card text say:

Attack a Stronghold with a besieging Army containing Isengard units.

My question is: when I play the card, must the Army already be besieging or not? And, in case of not, must adjacent to that Stronghold?

(Other cards have the same issue - e.g. Grond, Hammer of the Underworld)

Yes, the army must already be besieging the Stronghold.
