Actum (now La Punta), a promontory and village in Acarnania, at the entrance of the Ambracian gulf, near which Octavius, afterward Augustus, vanquished Mark Antony, Sept. 2, 31 B. C, in a great naval engagement which decided the question of universal dominion, and made the victor emperor. The generals had nearly equal armies on opposite sides of the bay, but these took no part in the combat. Octavius had 2G0 ships, Antony 220. Cleopatra reinforced Antony with 6O ships, and he imprudently offered a naval battle to Octavius. Agrippa, the admiral of Octavius, by a rapid manœevre, soon put to flight Cleopatra with her galleys. The voluptuous Antony followed her with a few ships. His fleet, deserted by its leader, surrendered, and his army did the like after waiting seven days for his return.
