The arrangements agreed on at Luca respecting the military command of Gaul were submitted directly to the burgesses by Crassus and Pompeius, those relating to Spain and Syria by the tribune of the people Gaius Trebonius, and in other instances the more important governorships were frequently filled up by decree of the people. That the regents did not need the consent of the authorities to increase their troops at pleasure, Caesar had already sufficiently shown: as little did they hesitate mutually to borrow troops; Caesar for instance received such collegiate support from Pompeius for the Gallic, and Crassus from Caesar for the Parthian, war. The Transpadanes, who possessed according to the existing constitution only Latin rights, were treated by Caesar during his administration practically as full burgesses of Rome.(7)
7. This is not stated by our authorities. But the view that Caesar levied no soldiers at all from the Latin communities, that is to say from by far the greater part of his province, is in itself utterly incredible, and is directly refuted by the fact that the opposition-party slightingly designates the force levied by Caesar as "for the most part natives of the Transpadane colonies" (Caes. B. C. iii. 87); for here the Latin colonies of Strabo (Ascon. in Pison. p. 3; Sueton. Caes. 8) are evidently meant. Yet there is no trace of Latin cohorts in Caesar's Gallic army; on the contrary according to his express statements all the recruits levied by him in Cisalpine Gaul were added to the legions or distributed into legions.
It is possible that Caesar combined with the levy the bestowal of the franchise; but more probably he adhered in this matter to the standpoint of his party, which did not so much seek to procure for the Transpadanes the Roman franchise as rather regarded it as already legally belonging to them (iv. 457). Only thus could the report spread, that Caesar had introduced of his own authority the Roman municipal constitution among the Transpadane communities (Cic. Ad Att. v. 3, 2; Ad Fam. viii. 1, 2). This hypothesis too explains why Hirtius designates the Transpadane towns as "colonies of Roman burgesses" (B. G. viii. 24), and why Caesar treated the colony of Comum founded by him as a burgess-colony (Sueton. Caes. 28; Strabo, v. 1, p. 213; Plutarch, Caes. 29), while the moderate party of the aristocracy conceded to it only the same rights as to the other Transpadane communities, viz. Latin rights, and the ultras even declared the civic rights conferred on the settlers as altogether null, and consequently did not concede to the Comenses the privileges attached to the holding of a Latin municipal magistracy (Cic. Ad Att. v. 11, 2; Appian, B. C. ii. 26). Comp. Hermes, xvi. 30.
