XVII. After this immense success, Hannibal was urged by his friends to follow up his victory and enter Rome with the fugitives, promising that five days thereafter he should sup in the Capitol. It is not easy to say what reasons could have deterred him from doing so, and it seems rather as if some divinity prevented his march, and inspired him with the dilatory and timid policy which he followed. It is said that the Carthaginian, Barca, said to him, “You know how to win a victory, but do not know how to use one.” Yet so great a change was effected by this victory that he, who before it had not possessed a single city, market, or harbour in Italy, and had to obtain his provisions with the utmost difficulty by plunder, having no regular base of operations, but merely wandering about with his army as though carrying on brigandage on a large scale, now saw nearly the whole of Italy at his feet. Some of the largest and most powerful States came over to him of their own accord, and he attacked and took Capua, the most important city next to Rome itself.
It would appear that the saying of Euripides, that “adversity tries our friends,” applies also to good generals. That which before this battle was called Fabius’s cowardice and remissness, was now regarded as more than human sagacity, and a foresight so wonderful as to be beyond belief. Rome at once centred her last hopes upon Fabius, taking refuge in his wisdom as men take sanctuary at an altar, believing his discretion to be the chief cause of her surviving this present crisis, even as in the old Gaulish troubles. For though he had been so cautious and backward at a time when there seemed to be no imminent danger, yet now when every one was giving way to useless grief and lamentation, he alone walked through the streets at a calm pace, with a composed countenance and kindly voice, stopped all womanish wailings and assemblies in public to lament their losses, persuaded the Senate to meet, and gave fresh courage to the magistrates, being really himself the moving spirit and strength of the State, which looked to him alone to command it.
