My first act was to besiege and capture Capua with the stack I had in a fort nearby. With the fall of Capua, the road to Rome was guaranteed (aside from the fact the Julii were starting to invade the eastern side of the peninsula). I took some time to prepare for the coming battle against the Senate, strengthening my troops and recruiting two units of onagers. Then, I attacked.
I was met with a Senate force consisting of several generals and one Praetorian cohort, the rest were pre-Marian units. The battle was won mainly by the cavalry units I had, routing nearly every infantry unit and killing all generals, the Praetorians were an absolute [censored] to destroy however (I did buff them in the EDU file).
With the destruction of the Senate's main army and most of their generals rotting in the sunny Italian countryside, I marched to Rome. I was repelled two times (mainly because of the Praetorians) and only captured it when the garrison was 6 men strong. Now I find myself in a dire situation, the Scipii have blockaded Capua and sent two stacks towards Rome. The reinforcements from Greece are coming to take over the rest of Italy but Corsica, Sardinia and Sicily have to be invaded as well in order to stage a naval invasion of the Scipii's territory in Africa, after that the Julii will be easily brought down.
