force.
This maner of fortificacion was observed of the Pisans, when you
besieged theim, and thei might doe it, bicause thei had strong walles,
whiche gave them time, the yearth beyng softe and moste meete to raise
up banckes, and to make fortificacions: where if thei had lacked this
commoditie, thei should have loste the toune. Therefore it shall bee
alwaies prudently doen, to provide afore hand, makyng diches within the
citee, and through out all the circuite thereof, as a little before wee
devised: for that in this case, the enemie maie safely be taried for at
laisure, the fortificacions beyng redy made. The antiquitie many tymes
gotte tounes, with muinyng under ground in twoo maners, either thei made
a waie under grounde secretely, whiche risse in the toune, and by
thesame entered, in whiche maner the Romaines toke the citee of Veienti,
or with the muinyng, thei overthrewe a walle, and made it ruinate: this
laste waie is now a daies moste stronge, and maketh, that the citees
placed high, be most weake, bicause thei maie better bee under muined:
and puttyng after in a Cave of this Gunne pouder, whiche in a momente
kindelyng, not onely ruinateth a wall, but it openeth the hilles, and
utterly dissolveth the strength of them.

[Sidenote: The reamedie against Caves or undermuinynges; What care the
besieged ought to have; What maketh a citee or campe difficulte to bee
defended; By what meanes thei that besiege ar made afraied; Honour got
by constancie.]

The remedie for this, is to builde in the plain, and to make the diche
that compasseth thy citee, so deepe, that the enemie maie not digge
lower then thesame, where he shall not finde water, whiche onely is
enemie to the caves: for if thou be in a toune, which thou defendest on
a high ground, thou canst not remedie it otherwise, then to make within
thy walles many deepe Welles, the whiche be as drouners to thesame
Caves, that the enemie is able to ordain against thee. An other remedie
there is, to make a cave againste it, when thou shouldeste bee aware
where he muineth, the whiche waie easely hindereth hym, but difficultly
it is foreseen, beyng besieged of a craftie enemie. He that is besieged,
ought above al thinges to have care, not to bee oppressed in the tyme of
reste: as is after a battaile fought, after the watche made, whiche is
in the Mornyng at breake of daie, and in the Evenyng betwen daie and
night, and above al, at meale times: in whiche tyme many tounes have
