11.14
While the fortifications of the camp were rapidly rising and part of the soldiers were garrisoning the country posts, part gathering in grain warily for fear of ambush, a horde of savages, outstripping by their extraordinary speed any rumour of their coming, with a sudden attack set upon Barbatio and the army he commanded, which was (as has been said) separated from the Gallic camp; and they followed them in their flight as far as Augst, and as much farther as they could; then, after seizing the greater part of his baggage and pack-animals, together with the camp-followers, they returned home again.
