From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
In the provinces and the dependent states Caesar had even less influence than in Italy. Transalpine Gaul indeed as far as the Rhine and the Channel obeyed him, and the colonists of Narbo as well as the Roman burgesses elsewhere settled in Gaul were devoted to him; but in the Narbonese province itself the constitutional party had numerous adherents, and now even the newly-conquered regions were far more a burden than a benefit to Caesar in the impending civil war; in fact, for good reasons he made no use of the Celtic infantry at all in that war, and but sparing use of the cavalry.
In the other provinces and the neighbouring half or wholly independent states Caesar had indeed attempted to procure for himself support, had lavished rich presents on the princes, caused great buildings to be executed in various towns, and granted to them in case of need financial and military assistance; but on the whole, of course, not much had been gained by this means, and the relations with the German and Celtic princes in the regions of the Rhine and the Danube,--particularly the connection with the Noric king Voccio, so important for the recruiting of cavalry,--were probably the only relations of this sort which were of any moment for him.
