C. Julius Caesar, Gallic War

The latter demands hostages from the remaining states; nay, more, appointed a day for this proceeding; he orders all the cavalry, fifteen thousand in number, to quickly assemble here; he says that he will be content with the infantry which he had before, and would not tempt fortune nor come to a regular engagement; but since he had abundance of cavalry, it would be very easy for him to prevent the Romans from obtaining forage or corn, provided that they themselves should resolutely destroy their corn and set fire to their houses; by which sacrifice of private property they would evidently obtain perpetual dominion and freedom. After arranging these matters, he levies ten thousand infantry on the Aedui and Segusiani, who border on our province: to these he adds eight hundred horse. He sets over them the brother of Eporedirix, and orders him to wage war against the Allobroges. On the other side he sends the Gabali and the nearest cantons of the Arverni against the Helvii; he likewise sends the Ruteni and Cadurci to lay waste the territories of the Volcae Arecomici. Besides, by secret messages and embassies, he tampers with the Allobroges, whose minds, he hopes, had not yet settled down after the excitement of the late war. To their nobles he promises money, and to their state the dominion of the whole province.
