Plutarch, Cato the Younger
Bernadotte Perrin, Ed.

62. Cato suspected their change of heart, but would not tax them with it. However, he wrote to Scipio and Juba advising them to keep away from Utica, because the three hundred were not to be trusted, and sent away the letter-bearers. And now the horsemen who had escaped from the battle, in numbers quite considerable, rode up to Utica and sent three of their number to Cato. [2] These men, however, did not bring the same proposition from the whole body. For one party among them was bent on going off to Juba, another wanted to join Cato, while a third was prevented by fear from entering Utica. On hearing their views, Cato ordered Marcus Rubrius to attend to the three hundred; he was to accept quietly the lists of those who gave freedom to their slaves, and was to use no compulsion. [3] But Cato himself took the men of senatorial rank and went forth outside of Utica. Here he conferred with the leaders of the horsemen, entreating them not to abandon so great a number of Roman senators, and not to choose Juba as their commander instead of Cato, but to save others as well as save themselves by coming into a city which could not be taken by storm, and had grain and other requisite provision for very many years. [4] In these entreaties the senators also joined, and with tears; whereupon the leaders of the horsemen discussed the matter with the horsemen, while Cato sat down on a mound with the senators and awaited the answers.
