They can raise only the dead troops which died in the actual round, on bat OR vampire form, that doesn't matter. So, if two or more enemies hit the vampires, you'll lost a lot of them, because they're quite weak and they won't retaliate more than once.
Units with the "no retaliation" skill are a pain for them.
