[Sidenote: Hasdrubal Gisconis tertius Carthaginiensium dux. Livy 24, 41, cp. 25, 37.]
+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.
[Sidenote: The points of inherent importance in the conduct of a campaign,—time, place, secrecy, code of signals, agents, and method.]
+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.
[Sidenote: Things necessary. 1. Silence.]
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.
[Sidenote: 2. Knowledge of the capabilities of the force in moving.]
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.
