Occurring in 49 BC, it saw a significant force of Populares commanded by Gaius Antonius besieged on the island of Curicta by an Optimate fleet under Lucius Scribonius Libo and Marcus Octavius.

[1] Caesar seized numerous cities, towns and settlements such as Arretium, Auximum, Asculum and most significantly Corfinium as he moved down the Italian Peninsula.

[3] At some point during 49 BC, Marcus Octavius and Lucius Scribonius Libo were given command of Pompey's large fleet and directed to begin operations against Caesar's forces in the Adriatic Sea.

[7] An attempt was made to break out from the siege using rafts which were sent in by Lucius Minucius Basilus on the mainland, however the Optimates managed to capture many of these in nets of Cilician design which rose up from below the water.

In fact, one of Caesar's few mentions of these events claims that a centurion named Titus Pullo who was set against him during the Battle of Pharsalus had been instrumental in undermining Gaius Antonius' efforts to defend Curicta.
