The war which followed (the so-called first Punic War) lasted twenty-four years. It was fought out on the high seas and in the beginning it seemed that the experienced Carthaginian navy would defeat the newly created Roman fleet. Following their ancient tactics, the Carthaginian ships would either ram the enemy vessels or by a bold attack from the side they would break their oars and would then kill the sailors of the helpless vessel with their arrows and with fire balls. But Roman engineers invented a new craft which carried a boarding bridge across which the Roman infantrymen stormed the hostile ship. Then there was a sudden end to Carthaginian victories. At the battle of Mylae their fleet was badly defeated. Carthage was obliged to sue for peace, and Sicily became part of the Roman domains.
