Final battle in allies

In the final battle of Allies, at a moment, the Sith betrayed the Jedi but I wonder if Luke was fighting against Abeloth and others Sith or if was fighting only against Abeloth (badly explained in the book).
Your opinions?

They were definitely in conflict; Luke wanted to kill Abeloth and the Sith wanted to capture her. And Vestara's father took a swing at Luke, which was intercepted by Ben.

But beyond that, I don't recall another attack on Luke.
