Arsites

Arsites was satrap of Hellespontine Phrygia in the 4th century BC. His satrapy also included the region of Paphlagonia. In 340 BC, he sent a mercenary force under the leadership of the Athenian Apollodorus to defend Perinthos which was sieged by Philip II, possibly after Artaxerxes III's request. The operation was successful and prevented a further advance of Philip into Asian Minor. In the spring of 334 BC, however, Alexander the Great, after crossing the Hellespont, set foot in Asia Minor in the dominion of Aristes. Aristes then took part in the satrap coalition to counter the attacker. In the consequent war-council of Zelea he was foremost in opposing the scorched earth plan presented by the mercenary Memnon. In the battle of the Granicus, he commanded the Paphlagonian cavalry in the left Persian wing just to the right of Arsames and Memnon. Arsites fled from the battlefield at Granicus, but shortly afterwards committed suicide because the blame for the defeat could fall on him. His province was the first on Asian soil which fell into the hands of Alexander. Alexander then, appointed his general Calas as the new satrap of the province.

Arsites had a son named Mithropastes who fled to an island in the Persian Gulf after his father's death. From there he was taken in 325/324 BC by the naval commander Nearchos, whom he accompanied on the rest of his voyage.
