Battle of Megalopolis

The Battle of Megalopolis was fought in 331 BC between Spartan led forces and Macedonia. Alexander's regent Antipater led the Macedonians to victory over King Agis III.

Background
In the autumn of 333 BC, the Spartan King Agis III had met with the Persian commanders Pharnabazus and Autophradates, somewhere in the Aegean Sea, and revealed to them his plans for a war against Alexander&mdash;in Greece itself. The Persians agreed to support Agis; however, they could only spare him 30 talents and 10 ships. Agis also recruited the Greek mercenary survivors of Issus - who had served in the Persian army – a force of 8,000 veterans. In the summer of 331 BC, Agis defeated Corrhagus, the Macedonian general in command of the Peloponnese and the garrison of Corinth.

Meanwhile Antipater, Alexander's regent in Macedonia, was occupied in Thrace where the Macedonian general Memnon was involved in a rebellion. After that was solved, Antipater marched against King Agis. Antipater had recruited a large force, over 40,000 strong, with a core of Macedonian troops and substantial numbers of barbarians from the northern fringes of the empire, reinforced with troops from his Greek allies.

Battle
The final battle, fought near Megalopolis in Arcadia, ended in defeat for the Spartans. Early in the battle Antipater's lines broke, but in the end it was the sheer weight of numbers that brought victory to the Macedonians. It is written 5,300 died on the Spartan side and 3,500 on the Macedonian side. For the Spartans that meant a death toll of over 25 percent. King Agis, now wounded and unable to stand, ordered his men to leave him behind to face the advancing Macedonian army so that he could buy his men time to retreat. On his knees, the Spartan king slew several enemy soldiers before being finally killed by a javelin.
