But Pompey says, you know what, I'm not so sure if Caesar is beatable right now. He wasn't aware that Caesar only had one legion. Maybe there was a trick up Julius Caesar's sleeves. So Pompey takes his forces and retreats across the Adriatic to regroup with the intent of coming back and retaking Rome. And so you can imagine a lot of the senators, especially the powerful senators who are in opposition to Julius Caesar, go along with Pompey. So Julius Caesar, even though he's now in control of Rome, he knows that this isn't the end of it, that a civil war has become, that it's only a matter of time before Pompey's forces and these senators return and retake Rome. So he decides to take the fight to them.
