VII.--When it was reported to Caesar that they were attempting to make their route through our Province, he hastens to set out from the city, and, by as great marches as he can, proceeds to Further Gaul, and arrives at Geneva. He orders the whole Province [to furnish] as great a number of soldiers as possible, as there was in all only one legion in Further Gaul: he orders the bridge at Geneva to be broken down. When the Helvetii are apprised of his arrival, they send to him, as ambassadors, the most illustrious men of their state (in which embassy Numeius and Verudoctius held the chief place), to say "that it was their intention to march through the Province without doing any harm, because they had" [according to their own representations] "no other route:--that they requested they might be allowed to do so with his consent." Caesar, inasmuch as he kept in remembrance that Lucius Cassius, the consul, had been slain, and his army routed and made to pass under the yoke by the Helvetii, did not think that [their request] ought to be granted; nor was he of opinion that men of hostile disposition, if an opportunity of marching through the Province were given them, would abstain from outrage and mischief. Yet, in order that a period might intervene, until the soldiers whom he had ordered [to be furnished] should assemble, he replied to the ambassadors, that he would take time to deliberate; if they wanted anything, they might return on the day before the ides of April [on April 12th]. VIII.--Meanwhile, with the legion which he had with him and the soldiers who had assembled from the Province, he carries along for nineteen [Roman, not quite eighteen English] miles a wall, to the height of sixteen feet, and a trench, from the lake of Geneva, which flows into the river Rhone, to Mount Jura, which separates the territories of the Sequani from those of the Helvetii. When that work was finished, he distributes garrisons, and closely fortifies redoubts, in order that he may the more easily intercept them, if they should attempt to cross over against his will. When the day which he had appointed with the ambassadors came, and they returned to him, he says that he cannot, consistently with the custom and precedent of the Roman people, grant any one a passage through the Province; and he gives them to understand that, if they should attempt to use violence, he would oppose them. The Helvetii, disappointed in this hope, tried if they could force a passage (some by means of a bridge of boats and numerous rafts constructed for the purpose; others, by the fords of the Rhone, where the depth of the river was least, sometimes by day, but more frequently by night), but being kept at bay by the strength of our works, and by the concourse of the soldiers, and by the missiles, they desisted from this attempt.
