Doubles combat v. barbarians

[KrikkitTwo]

When does this SW flag apply

when attacking barbarians?
when defending against barbarians?
when defending against barbarians in that city?

I've heard that it may only be #3, can any one confirm?

As far as I am aware then it doubles your units offense and defense whenever or whereever you fight barbarians until effect expires. I have never heard or witnessed anything that led me to believe this isn't how it works.

I'm pretty sure it applies 100% of the time. You never lose a barb battle on cheiftan yet on higher levels you will.
