XXXVI.--Whilst this treaty was going forward, Domitius arrived at Massilia with his fleet, and was received into the city, and made governor of it. The chief management of the war was entrusted to him. At his command they send the fleet to all parts; they seize all the merchantmen they could meet with, and carry them into the harbour; they apply the nails, timber, and rigging, with which they were furnished to rig and refit their other vessels. They lay up in the public stores, all the corn that was found in the ships, and reserve the rest of their lading and convoy for the siege of the town, should such an event take place. Provoked at such ill treatment, Caesar led three legions against Massilia, and resolved to provide turrets, and vinae to assault the town, and to build twelve ships at Arelas, which being completed and rigged in thirty days (from the time the timber was cut down), and being brought to Massilia, he put under the command of Decimus Brutus; and left Caius Trebonius his lieutenant, to invest the city. XXXVII.--Whilst he was preparing and getting these things in readiness, he sent Caius Fabius one of his lieutenants into Spain with three legions, which he had disposed in winter quarters in Narbo, and the neighbouring country; and ordered him immediately to seize the passes of the Pyrenees, which were at that time occupied by detachments from Lucius Afranius, one of Pompey's lieutenants. He desired the other legions, which were passing the winter at a great distance, to follow close after him. Fabius, according to his orders, by using expedition, dislodged the party from the hills, and by hasty marches came up with the army of Afranius. XXXVIII.--On the arrival of Vibullius Rufus, whom, we have already mentioned, Pompey had sent into Spain, Afranius, Petreius, and Varro, his lieutenants (one of whom had the command of Hither Spain, with three legions; the second of the country from the forest of Castulo to the river Guadiana with two legions; the third from the river Guadiana to the country of the Vettones and Lusitania, with the like number of legions), divided amongst themselves their respective departments. Petreius was to march from Lusitania through the Vettones, and join Afranius with all his forces; Varro was to guard all Further Spain with what legions he had. These matters being settled, reinforcements of horse and foot were demanded from Lusitania, by Petreius; from the Celtiberi, Cantabri, and all the barbarous nations which border on the ocean, by Afranius. When they were raised, Petreius immediately marched through the Vettones to Afranius. They resolved by joint consent to carry on the war in the vicinity of Ilerda, on account of the advantages of its situation.
