6. On this being known at Rome, the utmost confusion and terror prevailed among the inhabitants, — this movement of Hannibal’s being as unexpected as it was sudden; for he had never been so close to the city before. At the same time their alarm was increased by the idea at once occurring to them, that he would not have ventured so near, if it were not that the armies at Capua were destroyed. Accordingly, the men at once went to line the walls, and the points of vantage in the defences of the town; while the women went round to the temples of the gods and implored their protection, sweeping the pavements of the temples with their hair: for this is their customary way of behaving when any serious danger comes upon their country. But just as Hannibal had encamped, and was intending to attempt the city itself next day, an extraordinary coincidence occurred which proved fortunate for the preservation of Rome.
For Gnaeus Fulvius and Publius Sulpicius, having already enrolled one consular army, had bound the men with the usual oath to appear at Rome armed on that very day; and were also engaged on that day in drawing out the lists and testing the men for the other army: whereby it so happened that a large number of men had been collected in Rome spontaneously in the very nick of time. These troops the Consuls boldly led outside the walls, and, entrenching themselves there, checked Hannibal’s intended movement. For the Carthaginians were at first eager to advance, and were not altogether without hope that they would be able to take Rome itself by assault. But when they saw the enemy drawn up in order, and learnt before long from a prisoner what had happened, they abandoned the idea of attacking the city, and began devastating the country-side instead, and setting fire to the houses. In these first raids they collected an innumerable amount of booty, for the field of plunder upon which they were entered was one into which no one had ever expected an enemy to set foot.
7. But presently, when the Consuls ventured to encamp within ten stades of him, Hannibal broke up his quarters before daylight. He did so for three reasons: — first, because he had collected an enormous booty; secondly, because he had given up all hope of taking Rome; and lastly, because he reckoned that the time had now come at which he expected, according to his original idea, that Appius would have learnt the danger threatening Rome, and would have raised the siege of Capua and come with his whole force to the relief of the city; or at any rate would hurry up with the greater part, leaving a detachment to carry on the siege. Publius had caused the bridges over the Anio to be broken down, and thus compelled Hannibal to get his army across by a ford; and he now attacked the Carthaginians as they were engaged in making the passage of the stream and caused them great distress. They were not able however to strike an important blow, owing to the number of Hannibal’s cavalry, and the activity of the Numidians in every part of the field. But before retiring to their camp they wrested the greater part of the booty from them, and killed about three hundred men; and then, being convinced that the Carthaginians were beating a hasty retreat in a panic, they followed in their rear, keeping along the line of hills. At first Hannibal continued to march at a rapid pace, being anxious to meet the force which he expected; but at the end of the fifth day, being informed that Appius had not left the siege of Capua, he halted; and waiting for the enemy to come up, made an attack upon his camp before daylight, killed a large number of them, and drove the rest out of their camp. But when day broke, and he saw the Romans in a strong position upon a steep hill, to which they had retired, he decided not to continue his attack upon them; but marching through Daunia and Bruttium he appeared at Rhegium, so unexpectedly, that he was within an ace of capturing the city, and did cut off all who were out in the country; and during this excursion captured a very large number of the Rhegini.
8. It seems to me that the courage and determination both of the Carthaginians and Romans at this crisis were truly remarkable; and merit quite as much admiration as the conduct of Epaminondas, which I will describe here for the sake of pointing the comparison.
He reached Tegea with the allies, and when he saw that the Lacedaemonians with their own forces in full were come to Mantinea, and that their allies had mustered together in the same city, with the intention of offering the Thebans battle; having given orders to his men to get their supper early, he led his army out immediately after nightfall, on the pretext of being anxious to seize certain posts with a view to the coming battle. But having impressed this idea upon the common soldiers, he led them along the road to Lacedaemon itself; and having arrived at the city about the third hour of his march, contrary to all expectation, and finding Sparta destitute of defenders, he forced his way right up to the market-place, and occupied the quarters of the town which slope down to the river. Then however a contretemps occurred: a deserter made his way into Mantinea and told Agesilaus what was going on. Assistance accordingly arrived just as the city was on the point of being taken; and Epaminondas was disappointed of his hope. But having caused his men to get their breakfast along the bank of the Eurotas, and recovered them from their fatigue, he started to march back again by the same road, calculating that, as the Lacedaemonians and their allies had come to the relief of Sparta, Mantinea would in its turn be left undefended: which turned out to be the case. So he exhorted the Thebans to exert themselves; and, after a rapid night march, arrived at Mantinea about midday, finding it entirely destitute of defenders.
But the Athenians, who were at that time zealously supporting the Lacedaemonians in their contest with the Thebans, had arrived in virtue of their treaty of alliance; and just as the Theban vanguard reached the temple of Poseidon, seven stades from the town, it happened that the Athenians showed themselves, by design, as if on the brow of the hill overhanging Mantinea. And when they saw them, the Mantineans who had been left behind at last ventured to man the wall and resist the attack of the Thebans. Therefore historians are justified in speaking with some dissatisfaction of these events, when they say that the leader did everything which a good general could, but that, while conquering his enemies, Epaminondas was conquered by Fortune.
9. Much the same remark applies to Hannibal. For who can refrain from regarding with respect and admiration a general capable of doing what he did? First he attempted by harassing the enemy with skirmishing attacks to raise the siege: having failed in this he made direct for Rome itself: baffled once more by a turn of fortune entirely independent of human calculation, he kept his pursuers in play, and waited till the moment was ripe to see whether the besiegers of Capua stirred: and finally, without relaxing in his determination, swept down upon his enemies to their destruction, and all but depopulated Rhegium. One would be inclined however to judge the Romans to be superior to the Lacedaemonians at this crisis. For the Lacedaemonians rushed off en masse at the first message and relieved Sparta, but, as far as they were concerned, lost Mantinea. The Romans guarded their own city without breaking up the siege of Capua: on the contrary, they remained unshaken and firm in their purpose, and in fact from that time pressed the Capuans with renewed spirit.
I have not said this for the sake of making a panegyric on either the Romans or Carthaginians, whose great qualities I have already remarked upon more than once: but for the sake of those who are in office among the one or the other people, or who are in future times to direct the affairs of any state whatever; that by the memory, or actual contemplation, of exploits such as these they may be inspired with emulation. For in an adventurous and hazardous policy it often turns out that audacity was the truest safety and the finest sagacity; and success or failure does not affect the credit and excellence of the original design, so long as the measures taken are the result of deliberate thought....
TARENTUM
When the Romans were besieging Tarentum, Bomilcar the admiral of the Carthaginian fleet came to its relief with a very large force; and being unable to afford efficient aid to those in the town, owing to the strict blockade maintained by the Romans, without meaning to do so he used up more than he brought; and so after having been constrained by entreaties and large promises to com
e, he was afterwards forced at the earnest supplication of the people to depart....
THE SPOILS OF SYRACUSE
10. A city is not really adorned by what is brought from without, but by the virtue of its own inhabitants....
The Romans, then, decided to transfer these things to their own city and to leave nothing behind. Whether they were right in doing so, and consulted their true interests or the reverse, is a matter admitting of much discussion; but I think the balance of argument is in favour of believing it to have been wrong then, and wrong now. If such had been the works by which they had exalted their country, it is clear that there would have been some reason in transferring thither the things by which they had become great. But the fact was that, while leading lives of the greatest simplicity themselves, as far as possible removed from the luxury and extravagance which these things imply, they yet conquered the men who had always possessed them in the greatest abundance and of the finest quality. Could there have been a greater mistake than theirs? Surely it would be an incontestable error for a people to abandon the habits of the conquerors and adopt those of the conquered; and at the same time involve itself in that jealousy which is the most dangerous concomitant of excessive prosperity. For the looker-on never congratulates those who take what belongs to others, without a feeling of jealousy mingling with his pity for the losers. But suppose such prosperity to go on increasing, and a people to accumulate into its own hands all the possessions of the rest of the world, and moreover to invite in a way the plundered to share in the spectacle they present, in that case surely the mischief is doubled. For it is no longer a case of the spectators pitying their neighbours, but themselves, as they recall the ruin of their own country. Such a sight produces an outburst, not of jealousy merely, but of rage against the victors. For the reminder of their own disaster serves to enhance their hatred of the authors of it. To sweep the gold and silver, however, into their own coffers was perhaps reasonable; for it was impossible for them to aim at universal empire without crippling the means of the rest of the world, and securing the same kind of resources for themselves. But they might have left in their original sites things that had nothing to do with material wealth; and thus at the same time have avoided exciting jealousy, and raised the reputation of their country: adorning it, not with pictures and statues, but with dignity of character and greatness of soul. I have spoken thus much as a warning to those who take upon themselves to rule over others, that they may not imagine that, when they pillage cities, the misfortunes of others are an honour to their own country. The Romans, however, when they transferred these things to Rome, used such of them as belonged to individuals to increase the splendour of private establishments, and such as belonged to the state to adorn the city....
SPAIN
11. The leaders of the Carthaginians, though they had conquered their enemies, could not control themselves: and having made up their minds that they had put an end to the Roman war, they began quarrelling with each other, finding continual subjects of dispute through the innate covetousness and ambition of the Phoenician character; among whom Hasdrubal, son of Gesco, pushed his authority to such a pitch of iniquity as to demand a large sum of money from Andobales, the most faithful of all their Iberian friends, who had some time before lost his chieftainship for the sake of the Carthaginians, and had but recently recovered it through his loyalty to them. When Andobales, trusting to his long fidelity to Carthage, refused this demand, Hasdrubal got up a false charge against him and compelled him to give up his daughters as hostages....
ON THE ART OF COMMANDING ARMIES
12. The chances and accidents that attend military expeditions require great circumspection; and it is possible to provide for all of them with precision, provided that a man gives his mind to the conduct of his plan of campaign. Now that fewer operations in war are carried out openly and by mere force, than by stratagem and the skillful use of opportunity, any one that chooses may readily learn from the history of the past. And again that operations depending on the choice of opportunity oftener fail than succeed is easily proved from experience. Nor can there be any doubt that the greater part of such failures are due to the folly or carelessness of the leaders. It is time therefore to inquire into the rules of this art of strategy.
Such things as occur in campaigns without having been calculated upon in any way we must not speak of as operations, but as accidents or casualties. It is the conduct of a campaign in accordance with an exact plan that I am to set forth: omitting all such things as do not fall under a scientific rule, and have no fixed design.
13. Every operation requires a time fixed for its commencement, a period and place for its execution, secrecy, definite signals, persons by whom and with whom it is to be executed, and a settled plan for conducting it. It is evident that the man who has rightly provided for each of these details will not fail in the ultimate result, while he who has neglected any single one of them will fail in the whole. Such is the order of nature, that one insignificant circumstance will suffice for failure, while for success rigid perfection of every detail is barely enough.
Leaders then should neglect no single point in conducting such expeditions.
Now the head and front of such precautions is silence; and not to allow either joy at the appearance of an unexpected hope, or fear, or familiarity, or natural affection, to induce a man to communicate his plans to any one unconcerned, but to impart it to those and those alone without whom it is impossible to complete his plan, and not even to them a moment sooner than necessary, but only when the exigencies of the particular service make it inevitable. It is necessary, moreover, not only to be silent with the tongue, but much more so in the mind. For it has happened to many generals before now, while preserving an inviolable silence, to betray their thoughts either by the expression of their countenances or by their actions.
The second requisite is to know accurately the conditions under which marches by day or night may be performed, and the distances to which they can extend, and not only marches on land, but also voyages by sea.
The third and most important is to have some knowledge of the seasons, and to be able to adapt the design to them.
Nor again is the selection of the ground for the operation to be regarded as unimportant, since it often happens that it is this which makes what seems impossible possible, and what seemed possible impossible.
Finally there must be no neglect of the subject of signals and counter signals; and the choice of persons by whom and with whom the operation is to be carried out.
14. Of these points some are learnt by experience, some from history, and others by the study of scientific strategy. It is a most excellent thing too that the general should have a personal knowledge both of the roads, and the locality which he has to reach, and its natural features, as well as of the persons by whom and with whom he is to act. If that is not possible, the next best thing is that he should make careful inquiries and not trust just any one: and men who undertake to act as guides to such places should always deposit security with those whom they are conducting.
These, and other points like them, it is perhaps possible that leaders may learn sufficiently from the mere study of strategy, whether practical or in books. But scientific investigation requires scientific processes and demonstrations, especially in astronomy and geometry; the working out of which is not much to our present point, though their results are important, and may contribute largely to the success of such undertakings.
The most important operation in astronomy is the calculation of the lengths of the days and nights. If these had been uniform it would not have been a matter requiring any study, but the knowledge would have been common to all the world: since however they not only differ with each other but also with themselves, it is plainly necessary to be acquainted with the increase and diminution of both the one and the other. How can a man calculate a march, and the distance practicable in a day or in a night, if he is unacquainted with the variation of these periods o
f time? In fact nothing can be done up to time without this knowledge, — it is inevitable otherwise that a man should be sometimes too late and sometimes too soon. And these operations are the only ones in which being too soon is a worse fault than being too late. For the general who overstays the proper hour of action only misses his chance, since he can find out that he has done so before he arrives, and so get off safely: but he that anticipates the hour is detected when he comes up; and so not only misses his immediate aim, but runs a risk of ruining himself altogether.
15. In all human undertakings opportuneness is the most important thing, but especially in operations of war. Therefore a general must have at his fingers’ ends the season of the summer and winter solstice, the equinoxes, and the periods between them in which the days and nights increase and diminish. For it is by this knowledge alone that he can compute the distance that can be done whether by sea or land. Again, he must necessarily understand the subdivisions both of the day and the night, in order to know at what hour to order the reveillé, or the march out; for the end cannot be attained unless the beginning be rightly taken. As for the periods of the day, they may be observed by the shadows or by the sun’s course, and the quarter of the heaven in which it has arrived, but it is difficult to do the same for the night, unless a man is familiar with the phenomenon of the twelve signs of the Zodiac, and their law and order: and this is easy to those who have studied astronomy. For since, though the nights are unequal in length, at least six of the signs of the Zodiac are nevertheless above the horizon every night, it is plain that in the same portions of every night equal portions of the twelve signs of the Zodiac rise. Now as it is known what portion of the sphere is occupied by the sun during the day, it is evident that when he has set the arc subtended by the diameter of his arc must rise. Therefore the length of the night is exactly commensurate with the portion of the Zodiac which appears above the horizon after sunset. And, given that we know the number and size of the signs of the Zodiac, the corresponding divisions of the night are also known. If however the nights be cloudy, the moon must be watched, since owing to its size its light as a general rule is always visible, at whatsoever point in the heaven it may be. The hour may be guessed sometimes by observing the time and place of its rising, or again of its setting, if you only have sufficient acquaintance with this phenomenon to be familiar with the daily variation of its rising. And the law which it too follows admits of being easily observed; for its revolution is limited by the period of one month, which serves as a model to which all subsequent revolutions conform.
