Battle of the Lipara Islands
From Conservapedia
The Battle of the Lipara Islands was fought in 260 B.C. as part of the First Punic War between Rome and Carthage. It was a naval engagement in which the Roman squadron under C. Cornelius Scipio was defeated. The Romans, being a land power and never building a real navy before, were no match for the Carthaginians who had roamed the Mediterranean for centuries.
