"If ever these same things happen to occur among a large group of men... the officers reject the idea of bludgeoning or slaughtering all the men involved [as is the case with a small group or an individual]. Instead they find a solution for the situation which chooses by a lottery system sometimes five, sometimes eight, sometimes twenty of these men, always calculating the number in this group with reference to the whole unit of offenders so that this group forms one-tenth of all those guilty of cowardice. And these men who are chosen by lot are bludgeoned mercilessly in the manner described above [see original text]."

Byzantine Emperor Maurice forbade in his Strategikon the decimatio and other brutal punishments. According to him, punishments where the rank and file see their comrades dying by the hands of their own brothers-in-arms could lead to collapse of morale. Moreover, it will seriously deplete the manpower of the fighting unit.
