Question about fighting ghosts in Echoes from Levia

Hi there.

I'm currently playing Echoes of Levia and I've successfully crossed the marshes and arrived on the island encampment. The problem is, I've now reached a scene where I've encountered the ghosts of the three children at the beginning of the game and I have to fight them. For some reason, I can't seem to get past this bit. Firstly, has anyone reached this point and secondly, do you have any suggestions as to how I can tackle three enimies at once? I've tried parrying their attacks, but at some point I always get stunned by one and clobbered by the other two and then it's game over. I hope this makes sense.
