Its usually not too hard to beat on the AS if they are taking pain from every other angle, ie Pahlava, Baktria, Hayasadan, Makedon, KH etc. So, diplomacy can help here.
The ptolies are a different story though... only answer is to beat them on the field. Repeatedly.
You have already taken too much for a retreat to be worthwhile IMO - fight to the last man!
