I think that Camp Half-Blood is one of those locations that move with the gods (maybe the Civil war is just when CHB turned up on Long Island, or got its name), so there probably wouldn't be any other camps in Europe. Maybe the gods sometimes go on holiday or something and end up having children in places like Europe. Those kids would be pretty screwed, especially in Europe - Heroes of Olympus made a pretty big deal about how dangerous Greece/Italy/much of Europe is for demigods - but if one of them survived (is Britain far enough away from Italy and Greece to be safe?), maybe because their parent (Poseidon seems like a good dad, for a god) took pity on them and helped them grow up, then maybe that's what happened for the demigod in WWII.
