Question has come up before in games and we have made a ruling, but I would like to get the opinion of other people to see if its correct.
The rules for blockades are simple, A square in a city’s outskirts that contains one or more enemy figures (either scouts or armies) does not generate production, trade, culture, coins, or resources for the city’s owner.
Obviously you can deny the owner of the city the trade provided by the buildings, but the +2 or +4 combat bonus is not mentioned in the above rule. Because of this, my group and myself have ruled that you cannot blockade the combat bonus from the buildings or great generals.
What are the thoughts of the other players?
