Catognatus, surrounded by his principal Ambactes, was present in the assembly of the magistrates when the envoy delivered his commission. Seeing them hesitating, he replied to the summons as follows: "Here is the object of your search. I am Catognatus; I have afforded an asylum to certain of the Helvetii, who are my friends, and whose hospitality I myself have shared; I am allied with the Helvetii as I am allied with the Romans. If the Romans had been beaten by the Helvetii, and any of them escaped from massacre had taken refuge here, would they consider it honourable for me to give them up to their enemies, had they come here in arms to demand them? If such was the usual conduct of the Romans, I should blush to be their ally. To the vague accusation respecting the influence I am alleged to have exercised over the policy of the Ædui, I have nothing to reply. The Ædui act according to their own good pleasure, and it is not for me to interfere with them. The Romans should demand satisfaction of the Ædui if they have not fulfilled their engagements. As to myself, the Romans have asked nothing of me, and I have promised them nothing: what business have they here? If they had a message to send me, was it necessary that the bearer should be escorted by a legion? Is this how allies should treat each other? Go and tell the legate that we are at home here; that if he comes as a friend we shall treat him as a friend; but that if he presumes to dictate to us and treat us as children, we shall answer him as men who know how to act for themselves." "He is right! he is right!" was the unanimous exclamation of the Ambactes; and overwhelming the envoy with insults, they thrust him out. Catognatus had to interpose to prevent the crowd from tearing him to pieces. Titurius was instructed to show the greatest possible consideration for the inhabitants, that the neighbouring peoples might not be irritated; and to adhere scrupulously to the terms of the demand transmitted by the envoy--simply to require the surrender of the Helvetii and Catognatus. On the other hand, his orders were to accomplish the expedition with all possible despatch, as Cæsar had but a few legions with him. The legate, therefore, refrained from investing the city and the Oppidum, and, as he had no reason to fear the immediate arrival of help to the enemy, he judged it best to direct all his efforts to the plateau, hoping to take the fortress by a vigorous effort. It was, however, to be feared that if the Oppidum was taken by assault, Catognatus and a part of the Helvetii might succeed in escaping. At night, therefore, the legate was devising a plan by which, with the eight thousand men or thereabouts of which his force consisted, he might at the same time prevent all means of escape from within, and make a vigorous attack upon the Oppidum, when a centurion came to tell him that some of the inhabitants requested a private interview with him.
