The Battle of Decimomannu, Battle of Cornus or Battle of Caralis was fought 215 BC on the island of Sardinia when a Carthaginian army sailed to the island to support a local revolt against Roman rule. The army, led by Hasdrubal the Bald, fought a Roman army of similar size under the praetor Titus Manlius Torquatus in the Fall of 215 BC somewhere between Sestu and Decimomannu, just north of Caralis. The Romans destroyed the Carthaginian army and then scattered their fleet in a sea battle south of Sardinia.
