But now to speak my own mind on the matter, I think we should make this
distinction. Either you have your country strongly defended, as the
Romans had and the Swiss have theirs, or, like the Carthaginians of old
and the King of France and the Italians at the present day, you have it
undefended. In the latter case you must keep the enemy at a distance
from your country, for as your strength lies not in men but in money,
whenever the supply of money is cut off you are undone, and nothing so
soon cuts off this supply as a war of invasion. Of which we have
example in the Carthaginians, who, while their country was free from
invasion, were able by means of their great revenues to carry on war in
Italy against the Romans, but when they were invaded could not defend
themselves even against Agathocles. The Florentines, in like manner,
could make no head against Castruccio, lord of Lucca, when he attacked
them in their own country; and to obtain protection, were compelled to
yield themselves up to King Robert of Naples. And yet, after
Castruccio’s death, these same Florentines were bold enough to attack
the Duke of Milan in his own country, and strong enough to strip him of
his dominions. Such valour did they display in distant wars, such
weakness in those that were near.
But when a country is armed as Rome was and Switzerland now is, the
closer you press it, the harder it is to subdue; because such States
can assemble a stronger force to resist attack than for attacking
others. Nor does the great authority of Hannibal move me in this
instance, since resentment and his own advantage might lead him to
speak as he spoke to Antiochus. For had the Romans suffered in Gaul,
and within the same space of time, those three defeats at the hands of
Hannibal which they suffered in Italy, it must have made an end of
them; since they could not have turned the remnants of their armies to
account as they did in Italy, not having the same opportunity for
repairing their strength; nor could they have met their enemy with such
numerous armies. For we never find them sending forth a force of more
than fifty thousand men for the invasion of any province; whereas, in
defending their own country against the inroad of the Gauls at the end
of the first Carthaginian war, we hear of them bringing some eighteen
hundred thousand men into the field; and their failure to vanquish the
Gauls in Lombardy as they had vanquished those in Tuscany arose from
their inability to lead a great force so far against a numerous enemy,
or to encounter him with the same advantages. In Germany the Cimbrians
routed a Roman army who had there no means to repair their disaster;
but when they came into Italy, the Romans could collect their whole
strength, and destroy them. Out of their native country, whence they
can bring no more than thirty or forty thousand men, the Swiss may
readily be defeated; but in their own country, where they can assemble
a hundred thousand, they are well-nigh invincible.
