When occupying a camp, the choice becomes available to you whether to Disperse the camp or simply to Raid it. Dispersing it will cause the camp to act like a defeated Barbarian camp does in the base game - the Clan will disappear, you will gain any Historical moments and benefits related to this, but you will not gain Gold! Instead, the unit doing the action will gain 10 XP. Raiding the camp leaves it intact, simply capturing a sum of Gold from it. The raiding unit will be ejected from the camp on the next turn, when a new barbarian unit appears there (this is called a 'Reprisal attack').This action does, however, set back that Clan's progress towards civilization, and can only be performed once every 10 turns.
