Imperial
Can an army entering another nation's home province with a defending army declare hostile and stay there without attacking?
Most posters read status as separate from the choice to fight, though some hold that hostile means fight; the rulebook says a battle needs one side to want it.
Yes. Declaring hostile sets the army's status toward the province, and a battle happens only when one side wants it, so both armies can stay. Some posters held that hostile means a fight, but the rulebook's battle rule points the other way.
