Taking the route toward the capital, he met the Romans at Lake Trasimenus, and totally routed them, killing the commander, Caius Flaminius, who had come from Arretium to oppose him. The defeat was accounted for by the Romans by the fact that Flaminius, always careless about his religious observances, had broken camp at Ariminum, whence he had come to Arretium, though the signs had been against him, and had also previously neglected the usual solemnities upon his election as consul before going to Ariminum. The policy of Hannibal was to make friends of the allies of Rome, in order to attract them to his support, and after his successes he carefully tended the wounded and sent the others away, often with presents. He hoped to undermine Rome by taking away her allies, and after this great success he did not march to the capital, though he was distant less than a hundred miles from it, because he expected to see tokens that his policy was a success. The dismay that fell upon Rome when it was known that her armies had twice been routed, can better be imagined than described. The senate came together, and for two days carefully considered the critical state of affairs. They decided that it was necessary to appoint a dictator, and Fabius Maximus was chosen. Hannibal in the meantime continued to avoid Rome, and to march through the regions on the Adriatic, hoping to arouse the inhabitants to his support. In vain were his efforts. Even the Gauls seemed now to have forgotten him, and Carthage itself did not send him aid. Fabius strove to keep to the high lands, where it was impossible for Hannibal to attack him, while he harassed him or tried to shut him up in some defile. In the spring of the year 216, both parties were prepared for a more terrible struggle than had yet been seen. The Romans put their forces under one Varro, a business man, who was considered the champion of popular liberty. The armies met on the field of Cannæ, on the banks of the river Aufidus which enters the Adriatic, and there the practical man was defeated with tremendous slaughter, though he was able himself to escape toward the mountains to Venusia, and again to return to Canusium. There he served the state so well that his defeat was almost forgotten, and he was actually thanked by the senate for his skill in protecting the remnant of the wasted army.
