Orontes fought at the Battle of Gaugamela on the Persian right flank with 40,000 units of infantry and 7,000 of cavalry under his command, where he died. His son, Mithrenes, Satrap of Lydia, had joined Alexander the Great after being defeated at Sardis in 334 BC, and fought at Gaugamela on the side of Alexander. After the battle, Mithrenes was made Satrap of Armenia by Alexander.
Aroandas II mentioned in an inscription from Mount Nemrut was identified with the Orontes who was a commander in the Battle of Gaugamela by Karl Julius Beloch and Herman Brijder. This Orontes was also inferred to be a descendant of Orontes I and his wife Rhodogune, possibly their son or grandson. On the other hand, Friedrich Karl Dörner was unsure whether ancient citations of connections of the bearers of the name Aroandas/Orontes with Armenia or their status as leaders of Armenian military units are compelling reasons for assuming that they were relatives. Dörner considered it very questionable whether Aroandas II mentioned in an inscription from Mount Nemrut is identical with the Orontes of Alexander's time; the author stressed the need to consider that in the course of the 4th century BC, besides the two ancestors of Antiochus I of Commagene, other bearers of the same name may have played a part in Persian politics.
