Does "Naked" mean Without Armour?

[euryalus]

Well, I think "they fought naked" means that many of them did not wear body armour. Some understanding of Latin might throw further light on the subject, and in this context it seems to me that the Roman word for naked was probably "nudus". This, however, has several possible meanings, including not only "nude" but also exposed, unembellished, defenceless or "wearing only a tunica". It is also my understanding that fragments of Celtic armour have been discovered by archaeologists - suggesting that some, at least, of the Ancient Britons wore armour.
