Spartacus and the Slavery of the Romans

Sparticus is said to have used an ingenious trick to sneak away at night. When the romans get up in the morning and move towards them, they find the slaves don't move. It does kind of show though, that his tactics are the tactics of the gladiators. They aren't seeking right out combat at this point. So if i've got a horde of escaped slaves and gladiators, rome would be the last place that i'd want to be. Generally, italy is the worst place to probably have them. But what could his intentions be? It is hard to know.
