 His forces outnumbered Alexander's soldiers by at least a 2 to 1 ratio, but Darius was still outflanked, defeated, and forced to flee.It is told by Arrian that at the Battle of Issus the moment the Persian left went to pieces under Alexander's attack and Darius, in his war-chariot, saw that it was cut off, he incontinently fled – indeed, he led the race for safety.On the way, he left behind his chariot, his bow, and his royal mantle, all of which were later picked up by Alexander.
