I might start another game as Carthage as try to do it again, then show a replay.
Im playing on Hard/Hard and yes the AI is very effective with its cavalry and even protecting its flanks a lot of the times.
Numerous occasions ive sent out cavalry on the flanks only to have to pull them back because the AI sent out infantry to intercept them, wheeling its infantry around to face the bulk of my main force at the last moment.

Of course after the battle is joined you can usually get your cavalry around the flanks and cause some damage.

The Gauls are easy, dont use them as any form of benchmark for anything. :)
