Scipio's fellow consul, Gaius Duilius, placed the Roman army units under subordinates and took command of the fleet. He promptly sailed, seeking battle. The two fleets met off the coast of Mylae in the Battle of Mylae. Hannibal had 130 ships, and the historian John Lazenby calculates that Duilius had approximately the same number. The Carthaginians anticipated victory, due to the superior experience of their crews, and their faster and more manoeuvrable galleys, and broke formation to close rapidly with the Romans. The first 30 Carthaginian ships were grappled by the and successfully boarded by the Romans, including Hannibal's ship – he escaped in a skiff. Seeing this, the remaining Carthaginians swung wide, attempting to take the Romans in the sides or rear. The Romans successfully countered and captured a further 20 Carthaginian vessels. The surviving Carthaginians broke off the action, and being faster than the Romans were able to escape. Duilius sailed to relieve the Roman-held city of Segesta, which had been under siege.
