§8.17.1Quod cum crebrius accideret, ex captivo quodam comperit Caesar Correum, Bellovacorum ducem, fortissimorum milia sex peditum delegisse equitesque ex omni numero mille, quos in insidiis eo loco collocaret, quem in locum propter copiam frumenti ac pabuli Romanos missuros suspicaretur.
As this happened rather frequently, Caesar learned from a certain prisoner that Correus, the leader of the Bellovaci, had selected six thousand of the bravest infantry and a thousand cavalry from the whole number, to place them in ambush in that place where he suspected the Romans would send troops on account of the abundance of grain and forage.
§8.17.2Quo cognito consilio legiones plures quam solebat educit equitatumque, qua consuetudine pabulatoribus mittere praesidio consuerat, praemittit: huic interponit auxilia levis armaturae; ipse cum legionibus quam potest maxime appropinquat.
Having learned of this plan, he led out more legions than he was accustomed to, and sent the cavalry ahead in accordance with the custom by which he had been used to send them as a guard for the foragers; among these he interspersed light-armed auxiliaries; he himself, with the legions, approached as closely as possible.
