Princes, then, have no worse enemy than conspiracy, for when a
conspiracy is formed against them, it either carries them off, or
discredits them: since, if it succeeds, they die; while, if it be
discovered, and the conspirators be put to death themselves, it will
always be believed that the whole affair has been trumped up by the
prince that he might glut his greed and cruelty with the goods and
blood of those whom he has made away with. Let me not, however, forget
to warn the prince or commonwealth against whom a conspiracy is
directed, that on getting word of it, and before taking any steps to
punish it, they endeavour, as far as they can, to ascertain its
character, and after carefully weighing the strength of the
conspirators with their own, on finding it preponderate, never suffer
their knowledge of the plot to appear until they are ready with a force
sufficient to crush it. For otherwise, to disclose their knowledge will
only give the signal for their destruction. They must strive therefore
to seem unconscious of what is going on; for conspirators who see
themselves detected are driven forward by necessity and will stick at
nothing. Of this precaution we have an example in Roman history, when
the officers of the two legions, who, as has already been mentioned,
were left behind to defend the Capuans from the Samnites, conspired
together against the Capuans. For on rumours of this conspiracy
reaching Rome, Rutilius the new consul was charged to see to it; who,
not to excite the suspicions of the conspirators, publicly gave out
that by order of the senate the Capuan legions were continued in their
station. The conspirators believing this, and thinking they would have
ample time to execute their plans, made no effort to hasten matters,
but remained at their ease, until they found that the consul was moving
one of the two legions to a distance from the other. This arousing
their suspicion, led them to disclose their designs and endeavour to
carry them out.
