Meanwhile Hannibal again crossed the mountains into the heart of Italy to Beneventum, and from there to Capua, the largest Italian city dependent upon Rome. The Dictator followed, condemning his soldiers to the melancholy task of looking on in inaction, while the enemy's cavalry plundered their faithful allies. Finally, Fabius obtained what he considered a favorable opportunity for an attack. Hannibal, disappointed in his expectations that Capua would be friendly to him, and not being prepared to lay siege to the town, had withdrawn towards the Adriatic. Fabius intercepted him near Casilinum, in Campania, on the left bank of the Volturnus. The heights that commanded the right bank of the river were occupied by his main army; and the road itself, which led across the river, was guarded by a strong division of men. Hannibal, however, ordered his light-armed troops to ascend the heights over the road during the night, driving before them oxen with burning fagots tied to their horns, giving the appearance of an army marching by torchlight. The plan was successful. The Romans abandoned the road and marched for the heights, along which they supposed the enemy were going. Hannibal, with a clear road before him, continued his march with the bulk of his army. The next morning he recalled his light-armed troops, which had been sent on to the hills with the oxen. Their engagement with the Romans had resulted in a severe loss to Fabius. Hannibal then proceeded, without opposition, in a northeasterly direction, by a very circuitous route. He arrived in Luceria, with much booty and a full money-chest, at harvest time. Near here he encamped in a plain rich in grain and grass for the support of his army. At Rome the policy of Fabius was severely criticised. His apparent inaction was displeasing to a large party, and he was called Cunctator (the Delayer). At length the assembly voted that his command be shared by one of his lieutenants, Marcus Minucius. The army was divided into two corps; one under Marcus, who intended to attack Hannibal at the first opportunity; the other under Fabius, who still adhered to his former tactics. Marcus made an attack, but paid dearly for his rashness, and his whole corps would have been annihilated had not Fabius come to his assistance and covered his retreat. Hannibal passed the winter of 217-216 unmolested. The season was spent by the Romans in active preparations for the spring campaign. An army of 80,000 infantry and 6,000 cavalry was raised and put under the command of the Consuls, LUCIUS AEMILIUS PAULLUS and GAIUS TERENTIUS VARRO. It was decided to test Hannibal's strength once more in open battle. His army was only half as strong as the Roman in infantry, but was much superior in cavalry.
