Persia and the Persians and the Persian Army - I'm Going to Take the Heavy Calvary and the Artillery

Alexander was always outnumbered he never brought to the battlefield more than 35 or 40,000 people at most maybe 18. The enemy usually had 60 to 70 to 80 000 he was sometimes two to one but he would look at the battlefield and say we've got to open a fisher where we can get to him so i'm going to saturate that point with artillery in the sense of javelin throwers or send the like calvary Send the archers that javelin and then once that fisher gets up I'm going to widen it. He led out amazingly brave he led every charge himself he was almost killed you can really see that famous painting  of Darius in his chariot
