No doubt Rome owed something, but not as much as her poets and orators pretended, to the cautious tactics of Quintus Fabius. At any rate, he gave her time to grow used to the presence of the invader and to recover from the shock of the three disasters with which the war opened. The Romans had never before been called upon to face a consummate strategist. Pyrrhus had been, within the limitations of Greek warfare, a clever tactician; he had even shown the originality to copy the Roman manipular system in his later battles. But Hannibal was more than a strategist; he was a psychologist who knew when the opposing general was rash and when he was wary, who had spies everywhere and could supplement their intelligence by disguising himself to do his own scouting. Scouting was an art that the Romans had yet to learn by bitter experience. At the Trasimene Lake[10] they blundered straight into the most obvious of natural death-traps. But the Romans were always good learners, and, as usually happens, the amateur patriot army steadily improved during the war while the hired professionals steadily deteriorated. The actual strategy by which Hannibal won most of his battles was simple enough. It was the policy of a long weak centre into which the Roman legions buried themselves deep while the two strong wings of the enemy closed round on their flanks and rear. In his Numidian horsemen Hannibal had the finest light cavalry yet known to European warfare. For a time all went brilliantly for the invader. Italians, Greeks, and Gauls joined his victorious standard. Rome was on the brink of despair. The very gods began to tremble; their statues sweated blood, two-headed lambs were born with alarming frequency, and cows in Apulia uttered prophetic warnings with human voices; the most horrible of omens portended destruction. But the city and the senate never lost heart and gradually as the years passed by Hannibal began to see that his cause was lost. The Latin allies stood firm for Rome. The Romans were able to hold Sicily and even despatch a brilliant and lucky young general named Scipio to reconquer Spain. Thus the longed-for reinforcements were cut off. The stupid aristocracy of Carthage were jealous of their great soldier, and when at last a reinforcing Punic army from Spain managed to slip through into Italy, Nero caught it at the River Metaurus just before the junction was effected. The first news of that battle came to Hannibal when the Romans tossed over the rampart into his camp the bleeding head of the defeated general, his own brother Hasdrubal. Horace has sung of this tragic episode in his noblest manner: quid debeas, o Roma, Neronibus testis Metaurum flumen et Hasdrubal devictus et pulcer fugatis ille dies Latio tenebris. * * * * *
