But if it ever happens that a number of men are involved in these same acts: if, for instance, some entire maniples have quitted their ground in the presence of the enemy, it is deemed impossible to subject all to the fustuarium or to military execution; but a solution of the difficulty has been found at once adequate to the maintenance of discipline and calculated to strike terror. The Tribune assembles the legion, calls the defaulters to the front, and, after administering a sharp rebuke, selects five or eight or twenty out of them by lot, so that those selected should be about a tenth of those who have been guilty of the act of cowardice. These selected are punished with the fustuarium without mercy; the rest are put on rations of barley instead of wheat, and are ordered to take up their quarters outside the vallum and the protection of the camp. As all are equally in danger of having the lot fall on them, and as all alike who escape that, are made a conspicuous example of by having their rations of barley, the best possible means are thus taken to inspire fear for the future, and to correct the mischief which has actually occurred.
