I have seen a lot of maps with arrows that show various tribes move around the mediterranean. But how did it happen in practice? Did the whole tribe simply pack up and leave? Did the whole tribe attack with all their women, children and elderly in toe??? That would mean that most people in the horde wouldn't have been capable of actually fighting. Wouldn't they have been extremely vulnerable to ANYBODY counterattacking them?

So were they just men planning to return home after they complete the raid? Were they young men looking for riches and women elsewhere never planning to return?
