Whosoever, therefore, would have a city defend itself stubbornly, or an army fight resolutely in the field, must before all things endeavour to impress the minds of those whom he commands with the belief that no other course is open to them. In like manner a prudent captain who undertakes the attack of a city, will measure the ease or difficulty of his enterprise, by knowing and considering the nature of the necessity which compels the inhabitants to defend it; and where he finds that necessity to be strong, he may infer that his task will be difficult, but if otherwise, that it will be easy. And hence it happens that cities are harder to be recovered after a revolt than to be taken for the first time. Because on a first attack, having no occasion to fear punishment, since they have given no ground of offence, they readily surrender; but when they have revolted, they know that they have given ground of offence, and, fearing punishment, are not so easily brought under. A like stubbornness grows from the natural hostility with which princes or republics who are neighbours regard one another; which again is caused by the desire to dominate over those who live near, or from jealousy of their power. This is more particularly the case with republics, as in Tuscany for example; for contention and rivalry have always made, and always will make it extremely hard for one republic to bring another into subjection. And for this reason any one who considers attentively who are the neighbours of Florence, and who of Venice, will not marvel so much as some have done, that Florence should have spent more than Venice on her wars and gained less; since this results entirely from the Venetians finding their neighbouring towns less obstinate in their resistance than the Florentines theirs. For all the towns in the neighbourhood of Venice have been used to live under princes and not in freedom; and those who are used to servitude commonly think little of changing masters, nay are often eager for the change. In this way Venice, though she has had more powerful neighbours than Florence, has been able, from finding their towns less stubborn, to subdue them more easily than the latter, surrounded exclusively by free cities, has had it in her power to do.
