Now some accounts say that this is really Bardia. This is really the other son of Cyrus the Great, and so there would be some legitimate claim to the throne. But there's other claims, especially the ones that Darius was later able to spread, that no, this was not the real Bardia. This was a fake Bardia, that the real Bardia had actually been killed by Cambyses II before, and that this person proposing to be Bardia was this fake usurper, this Zoroastrian priest named Gamatha. And once Cambyses is on his way, he's trying to come back in order to reclaim the throne, or in order to get rid of this usurper, whether it was the real Bardia or not. But on the way he dies, and once again it's under dubious circumstances. Cyrus the Great, how he died, not clear.
