Schlacht bei Issos
Later, the Spartan king Agis III recruited the Greek mercenary survivors of the Battle of Issus who had served in the Persian army, a force of 8,000 veterans, and used them in his fight against the Macedonians. In the summer of 331 BC, Agis defeated Coragus, the Macedonian general in command of the Peloponnese and the garrison of Corinth, but was finally defeated at the Battle of Megalopolis.
