Rome\'s most able general?

[Timotheus]

I would have to say by far Quintus Sertorius. Able genreal and leader who beat Pompey every time he met him on the battlefield even when Pompey had him outnumbered.

Anyone who calls slaps Pompey around that well and even calls him "Sulla's pupil" gets my vote.

If he had not been assasinated who knows how far he could have gone. There was certainly nothing the optimates of Rome could throw at him that fazed him at all.
