Quintus Curtius Rufus
In 326 BCE, Alexander's campaigns west of the Indus River brought him into conflict with the Assacani. In defence of their homeland, they assembled an army of 20,000 cavalry, 38,000 infantry, and 30 elephants, according to classical writer Quintus Curtius Rufus. Their army included a contingent of 7,000 Kamboj mercenaries recruited from Abhisara.
