(14 hours later... My bad!)
Alright! So, my army would consist of:
10 Urban Cohorts
4 Legionary First Cohort
4 Triarii
2 Light auxilia
Seems pretty basic, but here's what I would do. I would place the UCs in two lines of five at the center of my formation. I would place the LAs ahead of them. Two LFCs in columns on each side of the UCs and two Triarii behind each column. LAs are in spread formation and flee.
I would walk slowly until the LAs took fire from the catapults , then I would charge up until the hill. My infantry would then walk, except for the LAs who would rush up the hill and stay stationed, while attacking the UCs. By doing so, they would either take your archers' attention, use up some of your UCs spears, or draw out your cavalry. Either way, you can't let them go unnoticed. While you deal with them them, I'll have the rest of my army walk up the hill (Like this, they will be either Fresh or Warmed Up). I'll have my UCs rush your UCs during the last yards and try to engage them before too many spears are thrown.
By then your catapults and archers are useless as this is close combat. My LFCs would attack the side of your UC formation (When both of our UCs lose men, their ranks will become smaller, hence allowing my LFCs to make a smal flanking move). The LFCs will also give moral boosts to my men, ensuring they will stand up to your UCs. The Triarii behind each LFCs are there to keep your cavalry in check. Granted two units of Triari can't take two units of HC but whenever they'll become engaged, I'd just devote either a LFC or UC regiment to help them.
What do you think? I'm writing this late at night, so I don't know if it sounds coherent or not. =*
