command obedience by his arms. Fortresses are a doubtful source of
strength; against foreign foes they are worse than useless; against
subjects they are worthless in comparison with the goodwill of the
people: 'the best fortress possible is to escape the hatred of your
subjects.' Everything therefore depends upon the well-ordering of a
national militia. The neglect of that ruined the princes of Italy and
enabled Charles VIII. to conquer the fairest of European kingdoms with
wooden spurs and a piece of chalk.[2]

[1] In the _Discorsi_, lib. i. cap. 55, he calls Italy 'la
coruttela del mondo,' and judges that her case is desperate;
'non si può sperare nelle provincie che in questi tempi si
veggono corrotte, come è l' Italia sopra tutte le altre.'

xx.-xxiv. and chapter xii. of the _Principe_.

In his discourse on armies Machiavelli lays it down that the troops with
which a prince defends his state are either his own, or mercenaries, or
auxiliaries, or mixed. 'Mercenary and auxiliary forces are both useless
and perilous, and he who founds the security of his dominion on the
former will never be established firmly: seeing that they are disunited,
ambitious, and undisciplined, without loyalty, truculent to their
friends, cowardly among foes; they have no fear of God, no faith with
men; you are only safe with them before they are attacked; in peace they
plunder you; in war you are the prey of your enemies. The cause of this
is that they have no other love nor other reason to keep the field,
beyond a little pay, which is far from sufficient to make them wish to
die for you. They are willing enough to be your soldiers so long as you
are at peace, but when war comes their impulse is to fly or sneak away.
