in their liburnae galleys. Caesar rewarded his supporters in Liburnian Iader and Dalmatian Salona with the status of Roman colonies, but the battle was won by the Liburnian navy, prolonging the civil war, and ensuring control of the Adriatic to the side aligned with Pompey over the next 2 years until his final defeat in 48 BC. In the same year, Caesar sent his legions to take control of the rebellious Illyricum province, and took the fortress of Promona from Dalmatian hands, making them submit. Throughout this time, Roman rule in Illyricum province, largely nominal, was concentrated in only a few cities on the eastern Adriatic coast, such as Iader, Salona and Narona. Renewed Illyrian and Liburnian piracy motivated Octavian to organize a great military operation in Illyricum province in 35 BC, to finally stabilize Roman control of it. This action was first concentrated on the coastal Illyrian tribes to the east of Narona, then was expanded along the depth of Illyrian territory, where continental tribes gave much stronger resistance. After returning from the inland areas of Illyricum, Octavian destroyed the Illyrian pirate communities on the islands of Melita (Mljet) and Korkyra Nigra (Korčula), and continued to Liburnia, where he wiped out the last remnants of the Liburnian naval forces, thus resolving the problems of their renewed piratical activities in the bay of Kvarner (sinus Flanaticus) and their attempt to secede from Rome. Octavian commandeered all the Liburnian ships. Very soon these galleys would play a decisive role in the battle near Actium. Octavian made another expedition inland against the Iapodes from the Liburnian port of Senia (Senj), and conquered their most important positions in 34 BC. Over the next 2 years the Roman army, led by Marcus Vipsanius Agrippa, fought hard battles with the Dalmatae. The Liburnians were not recorded as participants in this war, but their southernmost territories were surely involved. It is uncertain whether the Liburnians joined in the last Great Illyrian Revolt; this remains debatable, as the only evidence is a damaged inscription found in Verona, mentioning the Iapodes and Liburnians under an unknown leader. Over the centuries, naval power was the most important aspect of warfare for the Liburni. After the empowered Roman forces defeated the Liburni, the region became part of the Roman province of Dalmatia, but it was considered marginal in a military sense. Burnum on the Krka river became a Roman military
