For so longe as men for their valiauntnesse, were then rewarded and had in estimacion, glad was he that could finde occasion to venter, yea, and spende his life, to benefite his countrie: as by the manly actes that Marcus Curcius, Oracius Cocles, and Gaius Mucius did for the savegarde of Rome and also by other innumerable like examples dooeth plainly appeare. But when through long and continuall peace, thei began to bee altogether given to pleasure and delicatenesse, little regardyng Marciall feates, nor soche as were expert in the practise thereof: Their dominions and estates, did not so moche before increase and prospere, as then by soche meanes and oversight, thei sodainly fell into decaie and utter ruine. For soche truly is the nature and condicion, bothe of peace and warre, that where in governemente, there is not had equalle consideration of them bothe, the one in fine, doeth woorke and induce, the others oblivion and utter abholicion. Wherfore, sith the necessitie of the science of warres is so greate, and also the necessarie use thereof so manifeste, that even Ladie Peace her self, doeth in maner from thens crave her chief defence and preservacion, and the worthinesse moreover, and honour of the same so greate, that as by prose we see, the perfecte glorie therof, cannot easely finde roote, but in the hartes of moste noble couragious and manlike personages, I thought most excellente Princes, I could not either to the specialle gratefiyng of your highnesse, the universall delight of all studious gentlemen, or the common utilitie of the publike wealth, imploie my labours more profitablie in accomplishyng of my duetie and good will, then in settyng foorthe some thing, that might induce to the augmentyng and increase of the knowledge thereof: inespecially thexample of your highnes most politike governemente over us, givyng plaine testimonie of the wonderfull prudente desire that is in you, to have your people instructed in this kinde of service, as well for the better defence of your highnesse, theim selves, and their countrie, as also to discourage thereby, and to be able to resist the malingnitie of the enemie, who otherwise would seeke peradventure, to invade this noble realme or kyngdome.
