Use Norman battle pulses and wide formations.You guys are forgetting unit sizes play a huge role in all this. cavalry can be butchered by skirmish units on huge unitsizes because they get bogged down and totally outnumbered. this is the slaves' only advantage... 200 men vs 100 cavalry? 2-1 = ouch time.
think of agincourt only instead of mud, slaves.
Charge, small melee, retreat, repeat.
You'll have the poor bastards running in no time from casualties and morale.
