C. Julius Caesar, Gallic War

1. While Caesar was in winter quarters in Hither Gaul, as we have shown above, frequent reports were brought to him, and he was also informed by letters from Labienus, that all the Belgae, who we have said are a third part of Gaul, were entering into a confederacy against the Roman people, and giving hostages to one another; that the reasons of the confederacy were these-first, because they feared that, after all [Celtic] Gaul was subdued, our army would be led against them; secondly, because they were instigated by several of the Gauls; some of whom as [on the one hand] they had been unwilling that the Germans should remain any longer in Gaul, so [on the other] they were dissatisfied that the army of the Roman people should pass the winter in it, and settle there; and others of them, from a natural instability and fickleness of disposition, were anxious for a revolution; [the Belgae were instigated] by several, also, because the government in Gaul was generally seized upon by the more powerful persons and by those who had the means of hiring troops, and they could less easily effect this object under our dominion.
