It is stated that Aquila was Caesar's legate.

In 60 BCE Caesar was busy getting rid of his debts (by fighting the Lusitanians) and campaigning to become consul.

After his consulate he originally intended to get the province of Illyricum (which had a higher war potential) but had a last minute "change of heart" and took the (already existing) provinces Gallia Cisalpina & Gallia Narbonensis. He must have been a hell of a fortune teller to know that in 58 BCE the Helvetii would try to pass Gallia Narbonensis (which more or less started his conquest of "rest" Gaul).

And the celtic tribes of Gaul where always of interest for Rome:

- the where relatively rich and had very good artisans

- they were somewhat afraid of them. Traumatized by gallic / celtic invasions (and even conquests / plundering of the city of Rome) in the past.
