[All] Does Celestial Bronze Hurt Non-Demigod Roman Campers?

Full disclosure, I just started reading the Percy Jackson books after wanting to for years. Now, my question is simple, but I haven't found a clear answer anywhere. Celestial Bronze is not supposed to affect mortals, only gods, demigods and monsters. But we find out that campers from the Roman Legion at Camp Jupiter are not necessarily demigods. Some are legacies, the descendants of demigods. So, had they gone into battle against Camp Half Blood, would the Greeks Celestial Bronze weapoms been effective against the legacy campers in the Roman Legion?
