Machiavelli, Volume I

by Niccolò Machiavelli

[THE SEVENTH BOOKE]

Tounes and Fortresses maie be strong twoo waies; The place that now a daies is moste sought to fortifie in; How a Toune walle ought to bee made; The walle of a toune ought to bee high, and the diche within, and not without; The thickenes that a Toune walle ought to bee of, and the distaunces betwene everie flancker, and of what breadth and deapth the dich ought to bee; How the ordinaunce is planted, for the defence of a toune; The nature of the batterie.

ou oughte to knowe, how that tounes and fortresses, maie bee strong either by nature, or by industrie; by nature, those bee strong, whiche bee compassed aboute with rivers, or with Fennes, as Mantua is and Ferrara, or whiche bee builded upon a Rocke, or upon a stepe hille, as Monaco, and Sanleo: For that those that stande upon hilles, that be not moche difficulct to goe up, be now a daies, consideryng the artillerie and the Caves, moste weake. And therfore moste often times in building, thei seke now a daies a plain, for to make it stronge with industrie. The firste industrie is, to make the walles crooked, and full of tournynges, and of receiptes: the whiche thyng maketh, that thenemie cannot come nere to it, bicause he maie be hurte, not onely on the front, but by flancke. If the walles be made high, thei bee to moche subjecte to the blowes of the artillerie: if thei be made lowe, thei bee moste easie to scale. If thou makeste the diches on the out side thereof, for to give difficultie to the Ladders, if it happen that the enemie fill them up (whiche a great armie maie easely dooe) the wall remaineth taken of thenemie. Therefore purposyng to provide to the one and thother foresaid inconveniences, I beleve (savyng alwaies better judgement) that the walle ought to be made highe, and the Diche within, and not without. This is the moste strongeste waie of edificacion, that is made, for that it defendeth thee from the artillerie, and from Ladders, and it giveth not facilitie to the enemie, to fill up the diche: Then the walle ought to be high, of that heighth as shall bee thought beste, and no lesse thick, then two yardes and a quarter, for to make it more difficult to ruinate. Moreover it ought to have the toures placed, with distances of CL. yardes betwen thone and thother: the diche within, ought to be at leaste twoo and twentie yardes and a halfe broad, and nine depe, and al the yearth that is digged out, for to make the diche, muste be throwen towardes the Citee, and kepte up of a walle, that muste be raised from the bottome of the diche, and goe so high over the toune, that a man maie bee covered behinde thesame, the whiche thing shal make the depth of the diche the greater. In the bottome of the diche, within every hundred and l. yardes, there would be a slaughter house, which with the ordinaunce, maie hurte whom so ever should goe doune into thesame: the greate artillerie that defende the citee, are planted behinde the walle, that shutteth the diche, bicause for to defende the utter walle, being high, there cannot bee occupied commodiously, other then smalle or meane peeses. If the enemie come to scale, the heigth of the firste walle moste easely defendeth thee: if he come with ordinaunce, it is convenient for hym to batter the utter walle: but it beyng battered, for that the nature of the batterie is, to make the walle to fall, towardes the parte battered, the ruine of the walle commeth, finding no diche that receiveth and hideth it, to redouble the profunditie of thesame diche: after soche sorte, that to passe any further, it is not possible, findyng a ruine that with holdeth thee, a diche that letteth thee, and the enemies ordinaunce, that from the walle of the diche, moste safely killeth thee. Onely there is this remedie, to fill the diche: the whiche is moste difficulte to dooe, as well bicause the capacitie thereof is greate, as also for the difficultie, that is in commyng nere it, the walle beeyng strong and concaved, betwene the whiche, by the reasons aforesaied, with difficultie maie be entered, havyng after to goe up a breache through a ruin, whiche giveth thee moste greate difficultie, so that I suppose a citee thus builded, to be altogether invinsible.

BAPTISTE. When there should bee made besides the diche within, a diche also without, should it not bee stronger?

FABRICIO. It should be without doubt, but mindyng to make one diche onely, myne opinion is, that it standeth better within then without.

BAPTISTE. Would you, that water should bee in the diches, or would you have them drie?

A drie diche is moste sureste.

FABRICIO. The opinion of men herein bee divers, bicause the diches full of water, saveth thee from mines under grounde, the Diches without water, maketh more difficulte the fillyng of them: but I havyng considered all, would make them without water, for that thei bee more sure: For diches with water, have been seen in the Winter to bee frosen, and to make easie the winnyng of a citee, as it happened to Mirandola, when Pope Julie besieged it: and for to save me from mines, I would make it so deepe, that he that would digge lower, should finde water.
