[-22-] Drusus and Tiberius meanwhile were concerned with the following undertakings. The Rhæti, who dwell between Noricum and Gaul, near the Tridentine Alps close to Italy, overran a good part of the adjacent territory of Gaul and carried plunder even out of Italy. Such of the Romans or their allies as used the road going through their country met with depredations. These actions of theirs were of course more or less like those of any nation which has not accepted terms of peace, but further they destroyed all the males among their captives, not only those who were apparent but also the embryo ones in the wombs of women, the sex of which they discovered by some divination. For these reasons Augustus first sent Drusus against them: he joined battle with a detachment of theirs that met him near the Tridentine mountains, and speedily had them routed; for this exploit he received the honors belonging to prætors. Later, when the tribe had been repulsed from Italy but still harassed Gaul, the emperor despatched Tiberius in addition. Both of the leaders then invaded the Rhætian country at many points at once,--the lieutenants leading such divisions as they did not command personally,--and Tiberius even crossed the lake[6] in boats. In this way, by encountering them separately, the Roman commanders spread alarm and had no difficulty in overcoming those who came near enough for fighting at any time, because they had only to deal with scattered forces; the remainder, who had become weaker and more despondent through such tactics, they captured. And because the land had a large population of males and seemed ripe for revolt, they deported most of those of military age, especially the strongest, leaving behind only so many as would be sufficient to inhabit the country but unable to make any uprising.
