Aretes

Aretes (Ἀρέτης) or Aretas (Ἀρέτας) was a Macedonian general. At the Battle of Gaugamela, he commanded the sarissophoroi (also known as prodromoi), a unit of versatile cavalry, adept at scouting, but with an ability for close-combat in battle. He replaced Protomachus as the commander of this unit. At Gaugamela, the sarissophoroi were responsible for finally routing the Persian left wing cavalry, winning the battle in this sector. In their final charge, the sarissophoroi broke the Massagetae heavy cavalry, Aretes personally killing their leader.
