As regards strange and unexpected sights, every captain should endeavour while his army is actually engaged with the enemy, to effect some such feint or diversion as will encourage his own men and dismay his adversary since this of all things that can happen is the likeliest to ensure victory. In evidence whereof we may cite the example of Cneius Sulpitius, the Roman dictator, who, when about to give battle to the Gauls, after arming his sutlers and camp followers, mounted them on mules and other beasts of burden, furnished them with spears and banners to look like cavalry, and placing them behind a hill, ordered them on a given signal, when the fight was at the hottest, to appear and show themselves to the enemy. All which being carried out as he had arranged, threw the Gauls into such alarm, that they lost the battle. A good captain, therefore, has two things to see to: first, to contrive how by some sudden surprise he may throw his enemy into confusion; and next, to be prepared should the enemy use a like stratagem against him to discover and defeat it; as the stratagem of Semiramis was defeated by the King of India. For Semiramis seeing that this king had elephants in great numbers, to dismay him by showing that she, too, was well supplied, caused the skins of many oxen and buffaloes to be sewn together in the shape of elephants and placed upon camels and sent to the front. But the trick being detected by the king, turned out not only useless but hurtful to its contriver. In a battle which the Dictator Mamercus fought against the people of Fidenae, the latter, to strike terror into the minds of the Romans, contrived that while the combat raged a number of soldiers should issue from Fidenae bearing lances tipped with fire, thinking that the Romans, disturbed by so strange a sight, would be thrown into confusion. We are to note, however, with regard to such contrivances, that if they are to serve any useful end, they should _be_ formidable as well as _seem_ so; for when they menace a real danger, their weak points are not so soon discerned. When they have more of pretence than reality, it will be well either to dispense with them altogether, or resorting to them, to keep them, like the muleteers of Sulpitius, in the background, so that they be not too readily found out. For any weakness inherent in them is soon discovered if they be brought near, when, as happened with the elephants of Semiramis and the fiery spears of the men of Fidenae, they do harm rather than good. For although by this last-mentioned device the Romans at the first were somewhat disconcerted, so soon as the dictator came up and began to chide them, asking if they were not ashamed to fly like bees from smoke, and calling on them to turn on their enemy, and “_with her own flames efface that Fidenae whom their benefits could not conciliate_,” they took courage; so that the device proved of no service to its contrivers, who were vanquished in the battle.
