The Battle of Crannon (322 BC), fought between the Macedonian forces of Antipater and Craterus and the forces of a coalition of cities including Athens and the Aetolian League, was the decisive battle of the Lamian War. The Macedonian victory, though militarily unspectacular, convinced the other Greeks to sue for peace.
