"Takes one Resource from a non-Germanic enemy that has pieces in the Region but neither Citadel nor Fort."
does it mean: SUBTRACT 1 RP from the enemy AND ADD it to your faction?
Exactly. If it had meant only 'subtract' it would have said "One non-Germanic enemy ... loses one Resource." I can understand the confusion, though.
