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. Alexander, warring in Asia at the time, called it a "battle of mice", according to Plutarch.
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—in Greece itself. The Persians agreed to support Agis; however, they could only spare for him 30 talents and 10 ships. Agis also recruited the Greek mercenary survivors of the Battle of Issus - who had served in the Persian army – a force of 8,000 veterans. In the summer of 331 BC, Agis defeated Coragus, the Macedonian general in command of the Peloponnese and the garrison of Corinth. Agis asked for help from the Peloponnesians and Athens, though Athens refused to help the Spartans.
