The Battle of Chaeronea was a battle between Greek city-states led by Athens and Thebes against King Philip II of Macedon. Philip used deception to lure the Greek infantry force into pursuing his troops across a river. This created a gap in their lines that Alexander exploited by leading his cavalry on a flanking maneuver against the Theban troops. Alexander relentlessly attacked the Thebans and destroyed their unit. With the Thebans defeated, Alexander then charged the main Greek force from the rear while Philip advanced from the front, trapping the Greeks between the two forces in a hammer and anvil maneuver that resulted in a decisive Macedonian victory.
