de bello gallico, 1.7

When it had been announced to Caesar that they were trying to make a journey through our province, he hurried to set out from the city and strove in the longest forced marches possible to farther Gaul, and he arrived at Genava. He levies the whole province as great a number of soldiers as possible (there was altogether one legion in farther Gaul), he ordered the bridge which was at Genava to be cut down. When the Helvetii were made aware (lit. more certain) about his arrival they sent ambassadors to him, the most noble of the state, of which legation Nammeius and Verucloetius were occupying the principal spot, who said that they had in mind to make a journey through the province without any misdeed, on account of the fact that they had no other route; they asked that it be allowed for them to do this by/with his willingness. Caesar, because he was holding in memory that Lucius Cassius the Consul had been killed and that his army had been beaten by the Helvetii and had been sent under the yoke, was not thinking that it should be yielded; and he was not thinking that the men of (lit. in) a hostile mind, with the means/opportunity of making a journey through the province having been given, would refrain from injury and misdeed. Nevertheless, that a space could intervene while soldiers gathered whom he had levied, he responded to the ambassadors that he would take a day for deliberating: if they wished anything they should return (let them return) on the Ides of April.
