Leucopetra (Wars of the Achæan League).

Fought 146 B.C., between a Roman Consular Army, under Lucius Mummius, and the forces of the Achæan League, under Diacus. The Greeks, who were only half as strong as their opponents, were routed, and all resistance came to an end, the Greek cities, one after another, opening their gates to the Romans.
