This seems to have been the reason why the Arvernian war, already almost at an end, once more broke out, and a second appeal to arms took place at Vindalium (above Avignon) at the confluence of the Sorgue with the Rhone.

The result was not different from that of the first: on this occasion it was chiefly the African elephants that scattered the Celtic army.

Thereupon the Arverni submitted to peace, and tranquillity was re-established in the land of the Celts.( 3) Province of Narbo The result of these military operations was the institution of a new Roman province between the maritime Alps and the Pyrenees.
All the tribes between the Alps and the Rhone became dependent on the Romans and, so far as they did not pay tribute to Massilia, presumably became now tributary to Rome.

In the country between the Rhone and the Pyrenees the Arverni retained freedom and were not bound to pay tribute to the Romans; but they had to cede to Rome the most southerly portion of their direct or indirect territory- the district to the south of the Cevennes as far as the Mediterranean, and the upper course of the Garonne as far as Tolosa (Toulouse).
As the primary object of these occupations was the establishment of a land communication between Italy and Spain, arrangements were made immediately thereafter for the construction of the road along the coast.

For this purpose a belt of coast from the Alps to the Rhone, from 1 to 1 3/4 of a mile in breadth, was handed over to the Massiliots, who already had a series of maritime stations along this coast, with the obligation of keeping the road in proper condition; while from the Rhone to the Pyrenees the Romans themselves laid out a military highway, which obtained from its originator Ahenobarbus the name of the -Via Domitia-.
Roman Settlements in the Region of the Rhone As usual, the formation of new fortresses was combined with the construction of roads.
