It seems that the Greeks and Macedonians were so superior to the Persians in melee that it is difficult to get an outright Persian win at Gaugamela, but you could certainly get a POD where Alexander is killed and the Macedonians have to retreat, a similar situation happened at Cunaxa. The Persians had actually prepared for the battle and maybe could have won outright.

So Alexander is killed and the Macedonians retreat in disorder. What happens?
