Does it make a difference what sort of elephants? I was fighting some armoured elephants from the Seleucid Empire recently and flaming arrows from two units of archers, an attack by two units of Persian spearmen in open order and a unit of cavalry made hardly any difference at all All my men died! The elephants then proceeded to chase my Cataphract general around the battlefield and it was only when I had defeated the rest of the army and could ganag up on the elephants that I could kill them.
