Clarification about Forts/Castles/Citadels

[EverNoob]

I tried a game building a network of forts with Ethne, then discovered that Castles didn't seem to give any combat bonus within +2 tile radius

Is that function working? Or is it there but it simply doesn't show up in the combat odds calculator?

It only affects units belonging to the castle's owner. Who the owner is is based on whose culture the castle is in.

It only works if said unit is defending.

It gets shut off if an enemy (I.E a unit hostile to the culture's owner) is standing in the castle.

doesn't it affect friendly units too, i.e. allies? I'm pretty sure a citadel does, not sure about castles and below though.

It only works if said unit is defending.

Ah, I thought it worked for attack within your borders too. That must've been it.
