55) This happened to me yesterday. Playing as Ethiopia, and Barbarians had been a pain. Lost my first warrior, lost an Archer to an unseen Horseman running in and finishing him off, lost a Scout to comp bow I couldn't see....
I took some time out of my build order to set three of the four cities to build Horsemen (my preferred anti-barb units: highly mobile for the economical empire). Two turns before they finish, a barbarian Horseman appears out of a camp I didn't know existed. Pillages my source of Horses, cancelling production, and then goes on a pillaging spree as my bows are off clearing an encampment for 2 citystates.
And as the cherry on top of this sundae, one of the city-states cleared the camp right as I got there.
