The Battle of Lake Tunis was a series of engagements of the Third Punic War fought in 149 BCE between the Carthaginians and the Roman Republic. Roman consuls Manius Manilius and Lucius Marcius Censorinus, leading separate forces, made several unsuccessful attempts to breach the walls of Carthage. Later, the Carthaginians launched fire ships, which destroyed most of the Roman fleet. Eventually Censorinus returned to Rome, leaving Manilius to continue fighting.
