Alea iacta esto

As I was crossing the Rubicon, word came to me by my scouts that Pompey Magnus and most of the Senate had fled south of Rome. This speaks volume about their confidence in Pompey to hold the city. When my legion and I approached the city after passing the Rubicon, I held the belief that Rome would be the hardest to take back from the Senate and Pompey, and that there would be a confrontation on the field of Mars. I could have not rolled a better hand than this. Rome's gates were open for my legion and I to simply return home. Of course, I had to wear my armor because at no point in time would I take off my armor as long as I felt there was a threat of assassins who favored Pompey and the Senate's agenda. Apparently, Pompey's legions had been dormant too long, and my veteran force seemed too experienced. Pompey's army has not seen action in many years. My legions are behind me all the way. I have stressed to my legion(s) what is at stake, and they share my ideology. Too long has the Senate and Roman politicians made me out to be the bad guy. Too long has the Senate benefited on the Roman people's misfortunes. There has to be something done, and I, Gaius Julius Caesar, am in perfect position to finally fulfill my destiny, to bring the Republic back to its former glory.
After spending a few days in Rome, I pursued Pompey. I knew that Pompey would not fight, but I had my reasons to pursue Pompey. The Senate and Pompey's agenda would hurt the public more than anything, and they must be stopped. Secondly, Pompey betrayed me. Once a brother and husband to my late daughter, Julia, Pompey sided with the Senate who has always had their eyes on me from the time I set foot in Roman politics. Pompey knew this, he exploited his way of gaining the Senate's approval, and he saw this as an opportunity to rise as pro-consul and favored by the Senate. However, he will never be the favorite of the people. I entered Rome as a conquering hero after the Senate and Pompey left. They seemed more like cowards to the people. I gave the people gifts of bread from the finest bakeries of Italia and gold from Gaul. The Roman people have never been so happy as to when they see me in the streets of Rome.
I went after Pompey with my 13th legion, though I was greatly outnumbered against Pompey's forces, and I wanted to capture Pompey and his legions before they could escape further from Rome. I left for Pompey, who was leaving for Hispania, and I left Marcus Antonius (Mark Antony) in control of Rome and it's well being as I leave Italia to pursue Pompey. After my legions marched for twenty-seven days, my army defeated Pompey's officers, and after the victory in Hispania, I returned east to Greece to fight Pompey.
