§8.2.1Quae ne opinio Gallorum confirmaretur, Caesar Marcum Antonium quaestorem suis praefecit hibernis; ipse equitum praesidio pridie Kal. Ianuarias ab oppido Bibracte proficiscitur ad legionem XIII, quam non longe a finibus Aeduorum collocaverat in finibus Biturigum, eique adiungit legionem XI, quae proxima fuerat.
Lest this opinion of the Gauls should be confirmed, Caesar placed Marcus Antonius the quaestor in command of his winter quarters; he himself, with a guard of cavalry, set out from the town of Bibracte on the day before the Kalends of January for the Thirteenth Legion, which he had stationed in the territory of the Bituriges, not far from the borders of the Aedui, and to it he joined the Eleventh Legion, which had been the nearest.
§8.2.2Binis cohortibus ad impedimenta tuenda relictis reliquum exercitum in copiosissimos agros Biturigum inducit, qui, cum latos fines et complura oppida haberent, unius legionis hibernis non potuerint contineri quin bellum pararent coniurationesque facerent.
Leaving two cohorts from each legion to guard the baggage, he led the rest of the army into the very fertile lands of the Bituriges, who, since they had extensive territories and numerous towns, could not be contained by the winter quarters of a single legion from preparing war and forming conspiracies.
