It was quite clear that with the two armies so near each other a battle could not be long delayed, and both commanders took what measures they thought necessary.
The way which Hannibal took to 'encourage' his army, as the Greek historian Polybius calls it, was rather a curious one, and reminds us of the manner in which lessons were taught in some of the old Bible stories.
While crossing the Alps he had captured a number of young Gauls in the very act of hurling rocks on the head of his army. Most commanders, both in that age and for very long after, would have put them to death at once, but Hannibal, unlike the Carthaginians, was never unnecessarily cruel, though he put his prisoners in chains and took care they should not escape. He now ordered these young men to be brought before him and placed in the centre of his troops, which were drawn up all round. On the ground near him lay some suits of armour, once worn by Gallic chiefs, and a pile of swords, while horses were tethered close by. Making a short speech, he then offered the young men a chance of saving their lives with honour, or meeting an honourable death at each other's hands. Would they take it, or would they rather remain prisoners?
A shout of joy answered him.
'Well, then,' said Hannibal, 'you will each of you draw lots which shall fight with the other, and the victor of every pair shall be given armour, a horse, and a sword, and be one of my soldiers.'
Pressing eagerly forward towards the urns which held the lots, the captives stopped to hold up their hands, as was their custom, praying to their gods for victory. After the lots were all drawn, they took their places, and under the eyes of the army the combat began. And when it was finished, and half the fighters lay dead on the field, it was they, and not the victors, who were envied by the soldiers, for having gloriously ended the misery of their lives. For in the old world death was welcomed as a friend, and seldom was a man found who dared to buy his life at the cost of his disgrace.
'The struggle between the captives,' said Hannibal to his army, 'is an emblem of the struggle between Carthage and Rome. The prize of the victors will be the city of Rome, and to those who fall will belong the crown of a painless death while fighting for their country. Let every man come to the battlefield resolved, if he can, to conquer, and if not to die.'
It was in this spirit that Hannibal trained his troops and led them to battle. He never made light of the difficulties that lay before him, or the dogged courage of the Romans, who rose up from every defeat with a fresh determination to be victorious. One advantage they had over Hannibal, and it could hardly be valued too highly. Though the councils of the senate who sent forth the troops might be divided, though the consuls who commanded them might be jealous of each other, yet the great mass of the army consisted of one nation, who together had fought for years under the eagles of Rome.
Hannibal, on the other hand, had to deal with soldiers of a number of different races, and his latest recruits, the Gauls, though eager and courageous, could not be depended upon in battle. When to this is added the fact that Hannibal was in a country which he did not know, among a people who feared Rome even while they hated her, and would desert him at the first sign of defeat; that he had to provide daily for the wants of both men and animals, and that for sixteen years he remained in Italy with a dwindling army, striking terror into the hearts of the bravest of the Romans, you may have some little idea of the sort of man he was.
Well may an historian say that the second Punic war was the struggle of a great man against a great nation. Take away Hannibal, and the Carthaginian forces were at the mercy of Rome.
We have no space to describe the various battles in the valley of the Po, in which Hannibal was always the victor. At the river Trebia he defeated Scipio in December 218, by aid of the strategy which never failed, till he taught his enemies how to employ it against himself. Hannibal was a man who never left anything to chance, and whether his generals were trusted to draw the enemy from a strong position into the open field, or to decoy it into an ambuscade, everything was foreseen, and as far as possible provided against. He took care that his troops and his animals should go into action fresh, well-fed, and well-armed, and more than once had the wounds of both horses and men washed with old wine after a battle. That tired soldiers cannot fight was a truth he never forgot or neglected.
During the winter months following the victory of Trebia, Hannibal pitched his camp in the territories of his Gallic allies, and busied himself with making friendly advances to the Italian cities which had been forced to acknowledge the headship of Rome. 'He had not come to fight against them,' he said, 'but against Rome, on their behalf.' So the Italian prisoners were set free without ransom, while the Roman captives were kept in close confinement. He also sent out spies to collect all the information they could as to the country through which he had to travel. He was anxious, for other reasons, to break up his camp as soon as he was able, as he saw signs that the Gauls were weary and rather afraid of having him for a neighbour.
Therefore, in the spring of 217 b. c. he marched southwards, placing the Spaniards and Libyans in front, with the baggage and stores behind them, the Gauls, whom he never quite trusted, in the centre, and the Numidian light horse and cavalry in the rear, under his brother Mago. There were no elephants to be thought of now, for they had all died of cold after the battle of Trebia. North of the Arno was a wide tract of marshland, which had to be crossed before the Apennine mountains could be reached. Never, during all his campaigns, did Hannibal's army have to undergo such suffering. In many ways it was worse than the passage of the Alps, for once in the midst of the morasses, swollen by the melting snows, it was hardly possible to snatch a moment of sleep. Many of the oxen fell and died, and when this happened the wearied men stretched themselves on their still warm bodies, and closed their eyes for a short space.
At length, after three nights and four days of incessant marching, till the troops were nearly numb with cold, firm ground was reached, and for a while they rested in peace on the hill of Fiesole, above the Arno.
Here Hannibal formed his plans for the next campaign. He found out that Flaminius the consul was a vain, self-confident man, with neither experience nor skill in war. It would be easy, he thought, by laying waste the rich country to the south, to draw the Roman general from his camp at Arretium; and so it proved. Flaminius, greedy of glory he could never gain, refused to listen to the advice of his officers and wait for the arrival of the other consul, and set out in pursuit of Hannibal, who felt that victory was once more in his hands.
The place which Hannibal chose for his battle was close to lake Thrasymene, a reedy basin in the mountains not far from the city of Cortona. At this spot a narrow valley ran down to the lake, with lines of hills on both sides, and a very steep mountain at the opposite end of the lake. At the lake end the hills came so close together that there was only a small track through which a few men could pass at a time.
Making sure that his enemy was following in his footsteps, Hannibal placed his steady heavy armed Spaniards and Libyans on the hill at the end of the valley opposite the lake, in full view of anyone who might approach them. His Balearic slingers and archers, and light-armed troops, were hidden behind the rocks of the hills on the right, and the Gauls and cavalry were posted in gorges on the left, close to the entrance of the defile, but concealed by folds in the ground. Next day Flaminius arrived at the lake, and, as Hannibal intended, perceived the camp on the hill opposite. It was too late to attack that night, but the next morning, in a thick mist, the consul gave orders for the advance through the pass. Grimly smiling at the success of his scheme, Hannibal waited till the Romans were quite close to him, and then gave the signal for the assault from all three sides at once.
Never in the whole of history was a rout more sudden and more complete. Flaminius' army was enclosed in a basin, and in the thick fog could get no idea from which direction the enemy was coming. The soldiers seemed to have sprung right out of the earth, and to be attacking on every quarter. All that the Romans could do was to fight, and fight they did with desperation. But there was no one to lead them, for their generals, like themselves, were bewildered, and Flaminius speedily met with the fate his folly deserved. Fifteen thousand Romans fell that day in the fierce battle, during which even an earthquake passed unheeded. Multitudes were pushed back into the lake and were dragged down to the bottom by the weight of their armour. Some fled to the hills and surrendered on the promise of their lives being spared, and a few thousands found their way back to Rome.
The victory being won, Hannibal charged the soldiers to seek for the body of Flaminius, so that he might give it honourable burial, by which nations in ancient times set special store. But, search as they might, they could not find it, nor was it ever known what became of him. Very differently did the Roman general Nero behave eleven years later on the banks of the Metaurus, when Hannibal's brother Hasdrubal, seeing that the day was lost, rode straight into the ranks of the enemy. When he fell, Nero, with savagery worthy of his namesake the emperor, cut off the head of the Carthaginian and threw it into Hannibal's camp.
There was silence in Rome when bands of wounded and weary soldiers came flying to the gates, bearing the news of this fresh disaster. Fifteen thousand men slain, fifteen thousand men taken prisoners! Hardly a family in Rome that was not stricken, and who could tell when the banners of the Carthaginians might not be seen on the crests of the hills? But as the troubles of life show the stuff of which men are made, Romans were never so great as when their cause seemed hopeless. The city was at once put in a state of defence, every boy and old man that could bear arms was sent to the walls, the bridges over the Tiber were destroyed, and the senate, putting aside the consuls, elected a dictator, who for six months had absolute power over the whole state.
The man who in this hour of sorest need was chosen to save the city was Quintus Fabius, whose policy of 'waiting' has become a proverb even to this day. He was already old, and was never a brilliant general, but, like most Romans, possessed great common-sense.
Alone among the senate he saw that there was no hope of conquering Hannibal in a pitched battle. Rome had not then – and, except for Cæsar, never has had – a single general with a genius equal to his; but there was one way, and one only, by which he might be vanquished, and that was to leave him where he was, in the midst of a hostile country, till his troops grew weary of expecting a battle which never was fought, and his Gallic allies became tired of inaction and deserted him.
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.
A howl of rage rang through Rome at the news that they had once more been outwitted, and all Fabius' wise generalship was forgotten in this fresh defeat. Yet, had they stopped to think, the fault did not lie with the dictator, whose plans had been well laid, but with the commander of the troops in the pass, who, instead of sending out scouts to find out the cause of the disturbance on the ridge, moved his whole body of men, leaving the defile unguarded. Perhaps Hannibal, in arranging the surprise, had known something of the commander and what to expect of him; or he may merely have counted – as he had often done before – on the effects of curiosity. But time after time he traded on the weakness of man, and always succeeded.
It was in June 216 b. c. that Hannibal gained his last great battle in Italy. He had remained for many months near the river Ofanto, which runs into the Adriatic, but in the beginning of summer he threw himself into the town of Cannæ, used by the Romans as a storehouse for that part of Italy.
A Roman army of ninety thousand men amply supplied was coming swiftly to meet him along the splendid roads, and he had only fifty thousand to cope with them, the greater number being Gauls, and not to be depended on. Of the original troops that he had brought from Spain, many were dead, but he was able to muster ten thousand cavalry, mostly consisting of the Numidian horse, and in this respect he was superior to the Romans. There was also to be reckoned to his advantage the fact that the two consuls, Varro and Paulus, hated each other bitterly, and that neither of them had any instinct of command, though Paulus was a capable soldier and a brave man.
There was a custom among the Romans, dating back from ancient days, that when the two consuls were serving on the same campaign, each should command on alternate days. It seems strange that such a very practical nation should have made such a foolish law, but so it was; and on this occasion it once more led, as it was bound to do, to an utter defeat. Hannibal played his usual game of sending Numidians across the river to insult and tease his enemy, till at length Varro exclaimed in wrath that the next day the command would be his, and that he would give the Carthaginians battle and teach them something of the majesty of Rome.
In vain the wiser Paulus, who had followed the counsels of Fabius, reasoned and protested. Varro would listen to nothing, and orders were given to the army to be ready on the morrow for the attack.
The day before the battle Hannibal spent 'in putting the bodies of his troops into a fit state to fight,' as the historian tells us – that is, he made them rest and sleep, and prepare plenty of food for their breakfast. Early next morning the Romans began to cross the river, which took several hours, thus leaving their strong camp on the southern bank with only a small force to defend it, and took up their position in the plains, where Hannibal's cavalry had ample room to manœuvre. And, to make matters worse, the consul formed his men into such close columns that they could not avoid being hampered by each other's movements.
The two armies when facing each other in order of battle must have presented a curious contrast. The Roman legions and their allies, amounting in all to seventy-six thousand men, wore helmets and cuirasses and carried swords and short throwing-spears. In front, the Carthaginian troops looked a mere motley crowd, so various were the dress and weapons of the different nations. It is true that the black-skinned Libyans might at first sight have been taken for deserters from the Roman camp, as they, like their enemies, were clad in the same armour and bore the same arms, the spoils of many a victory; and the young men of the legions trembled with rage as they beheld the glittering line, and thought of what it betokened. But the Gauls were almost naked, and their swords, unlike those of the Romans, could only cut, and were useless for thrusting, while the Spanish troops were clothed in a uniform of short linen tunics striped with purple. In the van, or front of the army, were the small remainder of the contingent from the Balearic Isles, with their slings and bows.
In spite of the faults committed by Varro in placing his troops, Hannibal's lines were once broken by the heavy-armed Roman soldiers, while the cavalry on the wing by the river were fighting in such deadly earnest that they leaped from their horses and closed man to man. But at Cannæ, as at Trebia, the honours of the day fell to the Numidians and to the Spanish and Gallic horse commanded by Hasdrubal. The Romans had been again routed by an army weaker by thirty thousand men than their own; the consul Paulus, and Servilius and Atilius, consuls of the year before, were all dead: only Varro saved his life by a disgraceful flight.
Still Hannibal did not march to Rome, as the senate expected. Though the battle of Cannæ decided the wavering minds of those who had been waiting to see on which side lay the victory; though the southern half of Italy and many cities of Campania were now anxious to throw in their lot with him; though Philip of Macedon promised once more to send ships and men to his support, and thousands of Gauls swarmed into his camp, the army on which he could actually rely was too small to besiege the city with any chance of success. He did, indeed, send ambassadors to Rome, with powers to treat for the ransoming of some Roman prisoners, but as before in the case of the Gauls, the envoys were not even given a hearing by the senate.
Till he got reinforcements from Carthage, Hannibal felt he must remain where he was; but surely she would delay no longer when she knew that the moment for which Hannibal was waiting had come, and his allies were ready. So he sent his brother Mago to tell the story of his triumphs and his needs to the Carthaginian senate, never doubting that a few weeks would see the tall-prowed ships sailing up the coast of the Tyrrhene sea, where he now had his headquarters. He did not reckon on the jealousy of his success which filled the breasts of the rulers of his country, a jealousy which even self-interest was unable to overcome. From the first he had borne their burden alone, and owing to the treachery and baseness of his own nation in the end it proved too heavy for his shoulders.
Soon Hannibal began to understand that he would get help from no one, and from Carthage least of all, and the knowledge was very bitter. The Romans had gathered together a fresh army of eighty or ninety thousand men, and had armed a large number of their slaves, offering them freedom. Any check, however slight, to the Carthaginian army was the cause of joy and thankfulness in Rome, for, as Livy says, 'not to be conquered by Hannibal then was more difficult than to vanquish him afterwards.'
In spite of Thrasymene and Cannæ things were now changed, and it was Hannibal who was on the defensive. The Romans had learned their lesson, and the legions always lying at the heels of Hannibal's army were commanded by experienced generals, who adopted the policy of Fabius and were careful never to risk a battle.
Thus three years passed away, and Carthage, absorbed in the difficult task of keeping Spain, from which she drew so much of her wealth, in her hands, sent thither all the troops she could muster to meet the Romans, who were gradually gaining ground in the peninsula.
In Italy the war was shifting to the south, and about 213 b. c. Hannibal was besieged in the town of Tarentum by a Roman fleet which had blocked the entrance to the gulf on which the city was situated. The alarm in Tarentum was great; escape seemed impossible; but Hannibal ordered boards to be placed in the night across a little spit of land that lay between the gulf and the open sea. When darkness fell, the boards were greased, and ox-hides stretched tightly over them. Then one by one the imprisoned Tarentine fleet was dragged along the boards and launched on the other side, and when all the ships were afloat, they formed in a line and attacked the Roman vessels, which were soon sunk or destroyed.
It was deeds such as these which showed the power Hannibal still possessed, and kept alive the Roman dread of him; yet he himself knew that the triumph of Rome was only a work of time, and that the kingdom of Carthage was slipping from her.
In Sicily, which had once been hers, and even now contained many towns which were her allies, a strong Roman party had arisen. Syracuse in the south was besieged by Appius Claudius by land and by Marcellus by sea, and its defence is one of the most famous in history. The Greek engineer, Archimedes, invented all sorts of strange devices new to the ancient world. He made narrow slits in the walls, and behind them he placed archers who could shoot through with deadly aim, while they themselves were untouched. He taught the smiths in the city how to make grappling irons, which were shot forth from the ramparts and seized the prows of the ships. By pressing a lever the vessels were slowly raised till they stood nearly upright, when the grapplers were opened, and the ships fell back with a splash that generally upset the crew into the sea, or were filled with water and sunk to the bottom. Of course you must remember that these were not great vessels with four masts like our old East Indiamen, but were long, high boats, worked by banks of oars, the shortest row being, of course, the lowest, nearest the water.
After a while the Romans got so frightened, not knowing what Archimedes might do next, that they thought every end of loose rope that was lying about hid some machine for their destruction. For a long while the engineer kept the enemy at bay, but in the end the power of Rome conquered; the beautiful marble palaces were ruined, and the paintings and statues which had been the glory of Syracuse were carried to Rome.
Just at this time news from Spain became more and more gloomy for the Carthaginians. The young Scipio, who had saved his father's life nine years before at the battle of the Ticinus, was, at the age of twenty-six, made commander-in-chief in the peninsula. Though never a great soldier, Scipio was a good statesman, and had the gift of winning men to his side. Multitudes of natives flocked to his standard, and many important places fell into his hands; and in his hour of victory he was merciful, and caused his captives as little suffering as possible. In the words of the people themselves, 'he had conquered by kindness.'
Seeing that for the time, at any rate, all was lost in Spain, Hasdrubal set out with an army to join his brother Hannibal. In Auvergne, in the centre of Gaul, where he spent the winter, large numbers of Gallic tribes joined him, and in the spring he crossed the Alps by the same pass as Hannibal. But the difficulties of nine years earlier were now absent, for the mountaineers understood at last that no evil to them was intended, and let the Carthaginian army climb the defile without attempting to hurt them. Traces of Hannibal's roads remained everywhere, and thus the troops, consisting perhaps of sixty thousand men, marched easily along and descended into the plains of the Po. But it was all useless; before Hasdrubal could join Hannibal, who was still in Apulia, the consul Nero, encamped near by at the head of a considerable force, made prisoners some messengers sent by the general to his brother.
Instantly taking steps to have the roads to the north watched by armies, Nero set off at night with a picked detachment to meet the consul Livius on the coast of the Adriatic, south of the river Metaurus. Night and day his men marched, eating as they went food brought them by the peasants. In less than ten days they had gone two hundred miles, and entered the camp of Livius by night, so that the Carthaginian general might know nothing of their arrival. Next morning Nero insisted, against the opinion of the other generals, that battle should be given immediately, as he must return and meet Hannibal at once. In vain they protested that his troops were too tired to fight; he shut his ears, the signal was sounded, and the army drawn up.
