Try to have at least two units of skirmisher cavalry targeting one unit of cataphracts. One of them leads the pursuing enemy around, while the other moves behind them, lobbing javelins to the backs of the enemy cavalry. Once you've run out of javelins, have one of your cavalry to charge them in close combat, and once they turn to face your chargers, have the other uni charge them as well.The enemy cataphracts will then be chopped to pieces with AP attacks.
