He had already lent a deaf ear to the injunctions of Catulus that he should dismiss the army; it was at least doubtful whether those of the senate would find a better reception, and the consequences of a breach no one could calculate-- the scale of aristocracy might very easily mount up, if the sword of a well-known general were thrown into the opposite scale.
So the majority resolved on concession.

Not from the people, which constitutionally ought to have been consulted in a case where a private man was to be invested with the supreme magisterial power, but from the senate, Pompeius received proconsular authority and the chief command in Hither Spain; and, forty days after he had received it, crossed the Alps in the summer of 677.
Pompeius in Gaul First of all the new general found employment in Gaul, where no formal insurrection had broken out, but serious disturbances of the peace had occurred at several places; in consequence of which Pompeius deprived the cantons of the Volcae-Arecomici and the Helvii of their independence, and placed them under Massilia.
He also laid out a new road over the Cottian Alps (Mont Genevre,( 21)), and so established a shorter communication between the valley of the Po and Gaul.

Amidst this work the best season of the year passed away; it was not till late in autumn that Pompeius crossed the Pyrenees.
Appearance of Pompeius in Spain Sertorius had meanwhile not been idle.

He had despatched Hirtuleius into the Further province to keep Metellus in check, and had himself endeavoured to follow up his complete victory in the Hither province, and to prepare for the reception of Pompeius.
The isolated Celtiberian towns there, which still adhered to Rome, were attacked and reduced one after another; at last, in the very middle of winter, the strong Contrebia (south-east of Saragossa) had fallen.

In vain the hard-pressed towns had sent message after message to Pompeius; he would not be induced by any entreaties to depart from his wonted rut of slowly advancing.
