obliged once more to shut itself up in its fortresses. Eryx soon fell
into the hands of the Romans (505), and the Carthaginians retained
nothing in the island but Drepana and Lilybaeum. Carthage a second
time offered peace; but the victory of Metellus and the exhaustion

success: they succeeded in introducing their fleet into the harbour
of the city, and in blockading it on the side facing the sea.
The besiegers, however, were not able to close the sea completely.
In spite of their sunken vessels and their palisades, and in spite of
the most careful vigilance, dexterous mariners, accurately acquainted
with the shallows and channels, maintained with swift-sailing vessels
a regular communication between the besieged in the city and the
Carthaginian fleet in the harbour of Drepana. In fact after some

They began with a regular attack; machines were erected, and in a

the walls, so that the breach soon appeared to be practicable. But
the able Carthaginian commander Himilco parried this assault by giving
