Some event Cards say "Recruit an army piece there and there", and some, but not all of them, say "Recruit only in a free territory":
1) Is there a difference between those cards?
And if so:
2) Can I use the first type to recruit in a besieged stronghold?
3) Can I use the first type to recruit in a conquered town/city/stronghold which contains no army pieces of the enemy?
4) Can I use both types if the nation is not at war? (I presume strongly yes, as we always played it that way)
