The siege of Lilybaeum lasted for nine years, from 250 to 241 BC, as the Roman army laid siege to the Carthaginian-held Sicilian city of Lilybaeum (modern Marsala) during the First Punic War. Rome and Carthage had been at war since 264 BC, fighting mostly on the island of Sicily or in the waters around it, and the Romans were slowly pushing the Carthaginians back. By 250 BC, the Carthaginians held only the cities of Lilybaeum and Drepana; these were well-fortified and situated on the west coast, where they could be supplied and reinforced by sea without the Romans being able to use their superior army to interfere.
