fighting in the Sertorian War (80-72 BCE) in Hispania. Pompey, one of the commanders in that war, had crossed Gaul to go to Hispania and subdued some (unspecified) rebellious tribes there. Pompey used Gallia Transalpina, which was on the road to Hispania and, therefore, his line of communications, as a base for his operations in the Iberian Peninsula. He wintered in Gaul in 75/74 BCE. Fonteius also raised corn for the Roman troops and a Gallic cavalry to support them. The Vocontii were mentioned by Julius Caesar (note that Further Province and Hither Province stand for Gallia Transalpina and Gallia Cisalpina; the latter was in northern Italy) : ... Here (in the Alps) the Ceutrones and the Graioceli and the Caturiges, having taken possession of the higher parts, attempt to obstruct the army in their march. After having routed these in several battles, he arrives in the territories of the Vocontii in the Further Province on the seventh day from Ocelum, which is the most remote town of the Hither Province; thence he leads his army into the country of the Allobroges,... Caesar was marching from Italy to the vicinity of Lake Geneva to confront the Helvetii. The historian Pompeius Trogus was a Vocontian. His grandfather served in the army of Pompey in Hispania during the Sertorian War . The Vocontii are later mentioned by Tacitus (Histories, in relation to the Revolt of Vitellius, which took place in 69 CE: The army then proceeded by slow marches through the territory of the Allobroges and Vocontii, the very length of each day's march and the changes of encampment being made a matter of traffic by the general, who concluded disgraceful bargains to the injury of the holders of land and the magistrates of the different states, and used such menaces, that at Lucus, a municipal town of the Vocontii, he was on the point of setting fire to the place, when a present of money soothed his rage. The administrative reforms of Diocletian (reigned 284-305) abolished the old provinces and created new, smaller ones. The number of provinces was doubled. The Roman towns built on the site of or near Vocontian settlements close to the Rhône, Vasio and Noviomagus, and those on the River Drôme, Dia Augusta and Lucius Augustii, came under the Provincia Viennensis. Segusturo, and the area in the Alpes-de-Haute-Provence department came under the Provincia Narbonensis II Rivet gives
