After the Hellenic League defeated Persian satraps at the Battle of the Granicus, Darius III personally assumed command, gathered reinforcements, and executed a surprise march behind Alexander's advancing forces to sever their supply lines, compelling Alexander to countermarch and engage near the city of Issus.
On 5 November 333 BC, Alexander the Great's Hellenic League met Darius III's Achaemenid Persian forces near the mouth of the Pinarus River in southern Anatolia. The Macedonian forces decisively defeated the Persian army in what was the first direct encounter between the two commanders.
Darius III was forced to flee the battlefield, abandoning his family and treasury, both of which were captured by Alexander. The defeat significantly weakened Persian resistance and opened the Levant and Egypt to Macedonian advance.
