Page "Chariot" Paragraph 19

Herodotus mentions that the Libyans and the Indus satrapy supplied cavalry and chariots to Xerxes the Great's army.

However, by this time cavalry was far more effective and agile than the chariot, and the defeat of Darius III at the Battle of Gaugamela ( 331 BC ), where the army of Alexander simply opened their lines and let the chariots pass and attacked them from behind, marked the end of the era of chariot warfare.
