Procopius, History of the Wars, Books III and IV: The Vandalic War
“ But I think it not untimely to remind you of this one thing, that, if you on the present occasion but prove equal to your own selves in valour, straightway there will be an end for the Vandals of their hopes, and for you of the battle. Hence there is every reason why you should enter into this engagement with the greatest eagerness. For ever sweet to men is toil coming to an end and reaching its close. Now as for the host of the Vandals, let no one of you consider them. For not by numbers of men nor by measure of body, but by valour of soul, is war wont to be decided. ”
