At the same time that this message was delivered to Caesar, embassadors came from the Aedui and the Treviri ; from the Aedui to complain that the Harudes, who had lately been brought over into Gaul, were ravaging their territories; that they had not been able to purchase peace from Ariovistus, even by giving hostages: and from the Treviri , [to state] that a hundred cantons of the Suevi had encamped on the banks of the Rhine , and were attempting to cross it; that the brothers, Nasuas and Cimberius, headed them. Being greatly alarmed at these things, Caesar thought that he ought to use all dispatch, lest, if this new band of Suevi should unite with the old troops of Ariovistus, he [Ariovistus] might be less easily withstood. Having therefore, as quickly as he could, provided a supply of corn, he hastened to Ariovistus by forced marches.
