Plutarch, Fabius Maximus
Bernadotte Perrin, Ed.

8. After this he was summoned to Rome by the priests to assist in sundry sacrifices, and put his forces in charge of Minucius, who was not to give battle, nor engage the enemy in any way. Such were not only the commands of Fabius as dictator, but also his reiterated counsels and requests. To all these Minucius gave little heed, and straightway began to threaten the enemy. [2] One day he noticed that Hannibal had sent the larger part of his army off to forage, whereupon he attacked the residue, drove them headlong inside their trenches, slew many of .them, and inspired them all with the fear of being held in siege by him. When Hannibal's forces were reunited in their camp, Minucius effected a safe retreat, thereby filling himself with measureless boastfulness and his soldiery with boldness. [3] An exaggerated version of the affair speedily made its way to Rome, and Fabius, when he heard it, said he was more afraid of the success of Minucius than he would be of his failure. But the people were exalted in spirit and joyfully ran to a meeting in the forum. There Metilius their tribune mounted the rostra and harangued them, extolling Minucius, but denouncing Fabius, not as a weakling merely, nor yet as a coward, but actually as a traitor. [4] He also included in his accusations the ablest and foremost men of the state besides. They had brought on the war at the outset, he said, in order to crush the people, and had at once flung the city into the hands of a man with sole and absolute authority, that he might, by his dilatory work, give Hannibal an assured position and time to reinforce himself with another army from Libya, on the plea that he had Italy in his power.
