be had, that the one parte of the armie goe not a sunder from the other, or that thoroughe some goyng fast, and some softe, the armie become not slender:  the whiche thynges, be occation of dissorder:  therfore the heddes muste be placed in suche wise, that they may maintaine the pace even, causing to goe softe those that goe to fast, and to haste forward the other that goe to sloe, the whiche pace can not bee better ruled, then by the stroke of the drumme.  The waies ought to be caused to be inlarged, so that alwaies at least a bande of iiii. hundred men may marche in order of battaile.  The custome and the qualitie of the enemie ought to be considered, and whether that he wil assaulte thee either in the mornyng, or at none or in the evenynge, and whether he be more puisante with fotemen or horsemen, and accordyng as thou understandest, to ordeine and to provide for thy self.  But let us come to some particular accidente.  It hapneth sometime, that thou gettyng from the enemie, because thou judgest thy selfe inferiour, and therfore mindynge not to faight with him, and he comyng at thy backe, thou arivest at the banke of a river, passyng over the which, asketh time, so that the enemie is redie to overtake thee and to fayght with thee.  Some, which chaunsing to bee in suche perill, have inclosed their armie on the hinder parte with a diche, and fillyng the same full of towe, and firyng it, have then passed with the armie without beyng able to be letted of the enemie, he beyng by the same fire that was betwene them held backe.

ZANOBI.  I am harde of beliefe, that this fyre coulde stay theim, in especially because I remember that I have harde, howe Annone of Carthage, beyng besieged of enemies, inclosed him selfe on the same parte, with wodde, which he did set on fire where he purposed to make eruption.  Wherfore the enemies beyng not intentive on the same parte to looke to him, he made his armie to passe over the same flame, causing every man to holde his Target before his face for to defend them from the fire, and smoke.

[Sidenote:  Nabide a spartayne; Quintus Luttatius pollecie to passe over a river; How to passe a ryver without a bridge; A polecie of Cesar to passe a river, where his enemie beyng on the other side therof sought to lette hym.]

FABRICIO.  You saye well:  but consider you howe I have saied, and howe Annone did:  for as muche as I saied that they made a diche, and filled it with towe, so that he, that woulde passe over the same, should be constrained to contende with the diche and with fire:  Annone made the fire, without the diche, and because he intended to passe over it, he made it not great, for that otherwise without the diche, it shoulde have letted him.  Dooe you not knowe, that Nabide a Spartan beyng besieged in Sparta of the Romaines, set fire on parte of his towne to let the way to the Romaines, who alredie wer entred in?  And by meane of the same flame not onely
