The Battle of Catana took place in the summer of 397 BC. The Greek fleet under Leptines, the brother of Dionysius I of Syracuse, engaged the Carthaginian fleet under Mago near the city of Catana in Sicily. While the Greek army under Dionysius was present near the city of Catana during the battle, the Carthaginian army under Himilco was away in the interior of Sicily, making a detour around the erupting Mt. Etna. The Carthaginian fleet crushed the Greek fleet in the battle, which ultimately led to the siege of Syracuse by the Carthaginians later in 397 BC.
