Valour has its bounds as well as other virtues, which, once transgressed,
the next step is into the territories of vice; so that by having too
large a proportion of this heroic virtue, unless a man be very perfect in
its limits, which upon the confines are very hard to discern, he may very
easily unawares run into temerity, obstinacy, and folly. From this
consideration it is that we have derived the custom, in times of war, to
punish, even with death, those who are obstinate to defend a place that
by the rules of war is not tenable; otherwise men would be so confident
upon the hope of impunity, that not a henroost but would resist and seek
to stop an army.

The Constable Monsieur de Montmorenci, having at the siege of Pavia been
ordered to pass the Ticino, and to take up his quarters in the Faubourg
St. Antonio, being hindered by a tower at the end of the bridge, which
was so obstinate as to endure a battery, hanged every man he found within
it for their labour. And again, accompanying the Dauphin in his
expedition beyond the Alps, and taking the Castle of Villano by assault,
and all within it being put to the sword by the fury of the soldiers, the
governor and his ensign only excepted, he caused them both to be trussed
up for the same reason; as also did the Captain Martin du Bellay, then
governor of Turin, with the governor of San Buono, in the same country,
all his people having been cut to pieces at the taking of the place.

But forasmuch as the strength or weakness of a fortress is always
measured by the estimate and counterpoise of the forces that attack it
--for a man might reasonably enough despise two culverins, that would be
a madman to abide a battery of thirty pieces of cannon--where also the
greatness of the prince who is master of the field, his reputation, and
the respect that is due unto him, are also put into the balance, there is
