Such was the plan of warfare which Fabius proposed, but his own countrymen put many obstacles in the way of its success. Many times he was called a coward for declining a battle which would certainly have been a defeat; but he let such idle cries pass him by, and hung on Hannibal's rear, keeping his soldiers, many of whom were raw and untrained, under his own eye. In vain Hannibal drew up his men in order of battle and tried by every kind of insult to induce Fabius to fight. The old general was not to be provoked, and the enemy at length understood this and retired to his camp.
Immediately after the battle of Thrasymene, Hannibal, knowing quite well that he was not strong enough to attack Rome, had taken up his headquarters on the shores of the Adriatic, so as to be at hand if Philip of Macedon made a descent upon Italy, or Carthage sent the reinforcements her general had so frequently asked for. But it was as useless to trust to the promises of the one as to the patriotism of the other, and having laid waste the country nearly as far south as Tarentum, he suddenly crossed the Apennines to the plain on the western sea, where he hoped to gain over some of the cities to his cause. In this again he was doomed to disappointment, for the rich Campanian towns, notably Capua, richest of all, held aloof till they knew for certain who would be conqueror.
In all Hannibal's campaigns nothing is more surprising than the way he managed to elude his enemies, who were always close to him and always on the look-out for him; yet he went wherever he wished.
Seeing that he could not hope for support in Campania, Hannibal determined to carry off the stores and booty he had collected into a safe place east of the Apennines, in order that his troops might be well-fed during the winter. This Fabius learned through a spy, and, knowing that there was only one pass through the mountains, sent a body of four thousand men to occupy a position in ambush from which they might fall upon the Carthaginians as they entered the gorge, while he himself encamped with a large force on a hill near at hand.
We can imagine the old dictator's satisfaction when he had completed his arrangements for crushing the Carthaginians, and felt that this time he would put to silence the grumblings of the people in Rome.
Fabius passed the day in preparing his plan of the attack which was to take place on the morrow, perhaps now and then allowing his secret thoughts to linger a little on the triumph awaiting him at Rome. But that very night Hannibal ordered one of his generals to fell some trees and split them into faggots, which were to be piled close to where two thousand oxen were tethered outside the camp. The men wondered a little what was going to happen, but did as they were bid, and then, by Hannibal's directions, had supper and lay down to sleep. Very early in the morning they were awakened by Hannibal himself, who bade them follow him out of the camp and tie the faggots on to the horns of the oxen. This was soon done, and then the faggots were kindled by a burning torch, and the oxen were driven up a low ridge which stretched before the pass.
'Help the drivers get them on to the ridge,' he said to his light troops, 'and then pass them, shouting and making all the noise you can.'
The march was conducted silently for some distance, but no sooner did the soldiers break out into shrieks and yells than the oxen grew frightened and wildly rushed hither and thither. The Romans in the defile below heard the shouts and saw the bobbing lights, but could not tell what they meant. Leaving their post, the whole four thousand climbed the ridge, where they found the Carthaginians. But it was still too dark for the Romans to see what these strange lights really were, so they drew up on the ridge to wait till daybreak, by which time Hannibal and most of his army were safe through the pass, when he sent back some of his Spanish troops to help the force he had left behind him. The troops speedily defeated the entire army of Fabius, who had now come up, and then, joining Hannibal, pushed on to Apulia.
