Mylæ (First Punic War).
Fought B.C. 260, when the Roman fleet, under Caius Duilius, defeated the Carthaginians, under Hannibal, with loss of 50 ships, 3,000 killed and 7,000 prisoners. Duilius had introduced the boarding bridge, which was lowered on to the deck of the opposing galley, and this gave full scope to the superior powers of the Romans in hand-to-hand fighting.
