Those who gave him the most trouble were the Salassi, the transalpine Iapydes, the Segestani, the Dalmatians, the Dæsitiatæ, and the Pannonians, far distant from the Salassi, who occupy the higher Alpine mountains, difficult of access, the paths being narrow and hard to climb. For this reason they had not only preserved their independence, but had levied tolls on those who passed through their country. Vetus assaulted them unexpectedly, seized the passes by stratagem, and besieged them for two years. They were driven to surrender for want of salt, which they use largely, and they received a Roman garrison; but when Vetus went away they expelled the garrison forthwith, and, possessing themselves of the mountain passes, they mocked at the forces that Augustus sent against them, as unable to accomplish anything of importance. Thereupon Augustus, anticipating a war with Antony, acknowledged their independence and allowed them to go unpunished for their offences against Vetus. But as they were suspicious of what might happen, they laid in large supplies of salt and made
incursions into the Roman territory until Messala Corvinus
was sent against them and reduced them by hunger. In this way were the Salassi subjugated.
