Against breaches in the walls the defence was, as at the present day, to throw up new works; while mines were met by counter-mines, in which the enemy were either withstood at the point of the sword, or baffled by some other warlike contrivance; as by filling casks with feathers, which, being set on fire and placed in the mine, choked out the assailants by their smoke and stench. Where towers were employed for the attack, the defenders sought to destroy them with fire; and where mounds of earth were thrown up against the walls, they would dig holes at the base of the wall against which the mound rested, and carry off the earth which the enemy were heaping up; which, being removed from within as fast as it was thrown up from without, the mound made no progress.

None of these methods of attack can long be persisted in and the assailant, if unsuccessful, must either strike his camp and seek victory in some other direction, as Scipio did when he invaded Africa and, after failing in the attempt to storm Utica, withdrew from his attack on that town and turned his strength against the Carthaginian army in the field; or else recourse must be had to regular siege, as by the Romans at Veii, Capua, Carthage, Jerusalem, and divers other cities which they reduced in this way.

The capture of towns by stratagem combined with force is effected, as by the Romans at Palæopolis, through a secret understanding with some within the walls. Many attempts of this sort have been made, both by the Romans and by others, but few successfully, because the least hindrance disarranges the plan of action, and because such hindrances are very likely to occur. For either the plot is discovered before it can be carried out, as it readily may, whether from treachery on the part of those to whom it has been communicated, or from the difficulties which attend its inception, the preliminary arrangements having to be made with the enemy and with persons with whom it is not permitted, save under some pretext or other, to hold intercourse; or if it be not discovered while it is being contrived, a thousand difficulties will still be met with in its execution. For if you arrive either before or after the appointed time, all is ruined. The faintest sound, as of the cackling of the geese in the Capitol, the least departure from some ordinary routine, the most trifling mistake or error, mars the whole enterprise. Add to which, the darkness of night lends further terror to the perils of such undertakings; while the great majority of those engaged in them, having no knowledge of the district or places into which they are brought, are bewildered and disconcerted by the least mishap, and put to flight by every imaginary danger. In secret nocturnal enterprises of this sort, no man was ever more successful than Aratus of Sicyon, although in any encounter by day there never was a more arrant coward. This we must suppose due rather to some special and occult quality inherent in the man, than to success being naturally to be looked for in the like attempts. Such enterprises, accordingly, are often planned, but few are put into execution, and fewer still with success.

When cities are acquired by surrender, the surrender is either voluntary or under compulsion; voluntary, when the citizens appeal to you for protection against some threatened danger from without, as Capua submitted to the Romans; or where they are moved by a desire to be better governed, and are attracted by the good government which he to whom they surrender is seen exercising over others who have placed themselves in his hands; as was the case with the Rhodians, the Massilians, and others who for like causes gave themselves up to the Roman people. Compulsory surrenders take place, either as the result of a protracted siege, like those we have spoken of above; or from the country being continually wasted by incursions, forays, and similar severities, to escape which a city makes its submission.

Of the methods which have been noticed, the Romans, in preference to all others, used this last; and for four hundred and fifty years made it their aim to wear out their neighbours by invasion and by defeat in the open field, while endeavouring, as I have elsewhere said, to establish their influence over them by treaties and conventions. It was to this method of warfare therefore that they always mainly trusted, because, after trying all others, they found none so free from inconvenience and disadvantage—the procedure by siege involving expense and delay, that by assault, difficulty and danger, and that by secret practice, uncertainty and doubt. They found, likewise, that while in subduing one obstinate city by siege many years might be wasted, a kingdom might be gained in a single day by the defeat of a hostile army in the field.

CHAPTER XXXIII.—That the Romans intrusted the Captains of their Armies with the fullest Powers.

In reading this History of Titus Livius with a view to profit by it, I think that all the methods of conduct followed by the Roman people and senate merit attention. And among other things fit to be considered, it should be noted, with how ample an authority they sent forth their consuls, their dictators, and the other captains of their armies, all of whom we find clothed with the fullest powers: no other prerogative being reserved to itself by the senate save that of declaring war and making peace, while everything else was left to the discretion and determination of the consul. For so soon as the people and senate had resolved on war, for instance on a war against the Latins, they threw all further responsibility upon the consul, who might fight or decline battle as he pleased, and attack this or the other city as he thought fit.

That this was so, is seen in many instances, and especially from what happened during an expedition made against the Etruscans. For the consul Fabius having routed that people near Sutrium, and thinking to pass onward through the Ciminian forest into Etruria, so far from seeking the advice of the senate, gave them no hint whatever of his design, although for its execution the war had to be carried into a new, difficult, and dangerous country. We have further witness to the same effect, in the action taken in respect of this enterprise by the senate, who being informed of the victory obtained by Fabius, and apprehending that he might decide to pass onward through the aforesaid forest, and deeming it inexpedient that he should incur risk by attempting this invasion, sent two messengers to warn him not to enter Etruria. These messengers, however, did not come up with the consul until he had already made his way into that country and gained a second victory; when, instead of opposing his further advance, they returned to Rome to announce his good fortune and the glory which he had won.

Whoever, therefore, shall well consider the character of the authority whereof I speak, will see that it was most wisely accorded; since had it been the wish of the senate that a consul, in conducting a war, should proceed step by step as they might direct him, this must have made him at once less cautious and more dilatory; because the credit of victory would not then have seemed to be wholly his own, but shared by the senate on whose advice he acted. Besides which, the senate must have taken upon itself the task of advising on matters which it could not possibly understand; for although it might contain among its members all who were most versed in military affairs, still, since these men were not on the spot, and were ignorant of many particulars which, if they were to give sound advice, it was necessary for them to know, they must in advising have made numberless mistakes. For these reasons they desired that the consul should act on his own responsibility, and that the honours of success should be wholly his; judging that the love of fame would act on him at once as a spur and as a curb, making him do whatever he had to do well.

This matter I have the rather dwelt upon because I observe that our modern republics, such as the Venetian and the Florentine, view it in a different light; so that when their captains, commissaries, or provedditori have a single gun to place in position, the authorities at home must be informed and consulted; a course deserving the same approval as is due to all those other methods of theirs, which, one with another, have brought Italy to her present condition.
