Britannia - Round IV: Caledonian Turn

Caledonian card

Andy's Caledonians have two difficult-terrain areas, bringing them two population points, which are added to the two they have on the population track.

A look at the timeline, as well as the card above, shows the Caledonians have boats this turn, and Andy uses this ability to move one of the armies in Skye to the Orkneys, which otherwise would surely have fallen to the Picts.
