as it was called, could be let down and the boarders could swarm aboard him.
Simple as this device was, it proved a complete success. It changed the course of the war and the fate of the world. The small amount of invention needed to counteract the corvus was not apparently within the compass of the Carthaginian rulers. At the battle of Mylæ (260 B.C.) the Romans gained their first naval victory and captured or destroyed fifty vessels. At the great battle of Ecnomus (256 B.C.), "probably the greatest naval engagement of antiquity," in which seven or eight hundred big ships were engaged, the Carthaginians showed that they had learnt nothing from their former disaster. According to rule they outmanœuvred and defeated the Romans, but the corvus again defeated them. The Romans sank thirty vessels and captured sixty-four.
Thereafter the war continued with violent fluctuations of fortune, but with a continuous demonstration of the greater energy, solidarity, and initiative of the Romans. After Ecnomus the Romans invaded Africa by sea, and sent an insufficiently supported army, which after many successes and the capture of Tunis (within ten miles of Carthage) was completely defeated. They lost their sea ascendancy through a storm, and regained it by building a second fleet of two hundred and twenty ships within three months. They captured Palermo, and defeated a great Carthaginian army there (251 B.C.), capturing one hundred and four elephants, and making such a triumphal procession into Rome as that city had never seen before. They made an unsuccessful siege of Lilybæum, the chief surviving Carthaginian stronghold in Sicily. They lost their second fleet in a great naval battle at Drepanum (249 B.C.), losing one hundred and eighty out of two hundred and ten vessels; and a third fleet of one hundred and twenty battleships and eight hundred transports was lost in the same year partly in battle and partly in a storm.
For seven years a sort of war went on between the nearly exhausted combatants, a war of raids and feeble sieges, during which the Carthaginians had the best of it at sea. Then by a last supreme effort Rome launched a fourth fleet of two hundred keels, and
