Help on Battle of Cannae (Punic Wars)

It isn't too difficult. Just let place Pacorus in a War elephant, then concentrate your forces and just attack to the left. The mistake new players will probably make here is they would attack the enemy infantry general stationed in the left-most city. The best way is just to bait him out of the city using a war elephant and position hasdrubal and pacorus nearby. When the enemy general takes the bait and leaves the city, attack the city and occupy it, and if for some reason pacorus on a war elephant fails to one shot the city, just use destroy. After that, let most of your forces take the city in the middle, and let pacorus and hasdrubal march towards the last city. Pretty straight forward campaign.
