If you have a beacon tower you will get a flashing combat message when you are being attacked. Your combat icon will flash red which warns you that an attack is incoming. Click the combat icon and you’ll get a message describing the incoming attack. Based on your beacon tower level you will get more or less information about the attack. This only works if you are online. If you are not online then you won’t see the message. You’ll come back from your “job” to check on your cities and find a combat message saying you were plundered. Hopefully your defenses were strong enough to defend your city!
