No, it's okay. I like a good debate and I've researching about this for the last half an hour. I'm just under the influence of what we've been taught in classes and by the fact that, while iron was known in the 12th century, it wasn't yet used as much so I don't know whether it would be so common in an entire army at that point. Metals were always present and known far before they became a common place in the society. I'm sure they knew about iron, but would it be so wide-spread already that early on? It would take huge amounts of iron to make all those weapons and shields and armour and I'm not sure it was very cost efficient to switch on that that early; usually, in the beginning, something new is regarded as a rarity and it takes decades, even centuries for it to find its place in a civilization. The lack of data from that period (after the fall of the Mycenaean civilization) doesn't help either and to rely on Homer's depiction of a wealthy period rich in iron weaponry (which, in 12th century, would still be a novelty) is quite puzzling. Historians usually believe he just described his own period and I think I remember that most of the finds from the actual site of Troy are typical bronze age finds (along with bronze arrowheads). However, who knows; as I said, the Illiad is full of both facts and fiction; distinguishing between the two can be a pain in the ass, especially when the archaeological evidence is scarce.
