Battle of Cape Ecnomus.
The Battle of Cape Ecnomus was a naval battle fought off the coast of Sicily in 256 BC between the fleets of Carthage and the Roman Republic during the First Punic War (264–241 BC). The Carthaginian fleet was commanded by Hanno the Great and Hamilcar; the Roman fleet was led by the consuls for the year, Marcus Atilius Regulus and Lucius Manlius Vulso Longus. The Roman fleet of 330 warships sailed with approximately 140,000 men on board. The Romans' plan was to cross to Africa and invade the Carthaginian homeland, in what is now Tunisia. The Carthaginians were apparently aware of the Romans' intentions and mustered 350 warships off the south coast of Sicily to intercept them. With a combined total of about 680 warships carrying up to 290,000 crew and marines, the battle was possibly the largest naval battle in history by the number of combatants involved. After a prolonged and confused day of fighting the Carthaginians were decisively defeated.
