The army was now moving through the passes of the Pyrenees. The labour was great; no army had ever before crossed this mountain barrier; roads had to be made, streams bridged, and rocks blasted away, to allow the passage of the elephants and baggage wagons. Opinions have differed as to the explosives used by the Carthaginian miners, but it is certain that they possessed means of blasting rocks. The engineers of Hannibal's force possessed an amount of knowledge and science vastly in excess of that attained by the Romans at that time, and during the campaign the latter frequently endeavoured, and sometimes with success, by promises of high rewards, to induce Hannibal's engineers to desert and take service with them. A people well acquainted with the uses of sulphur and niter, skilled in the Oriental science of chemistry, capable of manufacturing Greek fire—a compound which would burn under water—may well have been acquainted with some mixture resembling gunpowder. The art of making this explosive was certainly known to the Chinese in very remote ages, and the Phoenicians, whose galleys traversed the most distant seas to the east, may have acquired their knowledge from that people.
The wild tribes of the mountains harassed the army during this difficult march, and constant skirmishes went on between them and Hannibal's light armed troops. However, at last all difficulties were overcome, and the army descended the slopes into the plains of Southern Gaul.
Already Hannibal's agents had negotiated for an unopposed passage through this country; but the Gauls, alarmed at the appearance of the army, and at the news which had reached them of the conquest of Catalonia, assembled in arms. Hannibal's tact and a lavish distribution of presents dissipated the alarm of the Gauls, and their chiefs visited Hannibal's camp at Elne, and a treaty was entered into for the passage of the army.
A singular article of this treaty, and one which shows the esteem in which the Gauls held their women, was that all complaints on the part of the natives against Carthaginian troops should be carried to Hannibal himself or the general representing him, and that all complaints of the Carthaginians against the natives should be decided without appeal by a council composed of Gaulish women. This condition caused much amusement to the Carthaginians, who, however, had no cause to regret its acceptance, for the decisions of this singular tribunal were marked by the greatest fairness and impartiality. The greater part of the tribes through whose country the army marched towards the Rhone observed the terms of the treaty with good faith; some proved troublesome, but were wholly unable to stand against the Carthaginian arms.
The exact route traversed by the army has been a subject of long and bitter controversy; but, as no events of very great importance occurred on the way, the precise line followed in crossing Gaul is a matter of but slight interest. Suffice that, after marching from the Pyrenees at a high rate of speed, the army reached the Rhone at the point where Roquemaure now stands, a short distance above Avignon.
This point had been chosen by Hannibal because it was one of the few spots at which the Rhone runs in a single stream, its course being for the most part greatly broken up by islands. Roquemaure lies sixty-five miles from the sea, and it was necessary to cross the Rhone at some distance from its mouth, for Rome was now thoroughly alarmed, and Scipio, with a fleet and powerful army, was near Marseilles waiting to engage Hannibal on the plains of Gaul.
During the last few days' march no inhabitants had been encountered. The Arecomici, who inhabited this part of the country, had not been represented at the meeting, and at the news of the approach of the Carthaginians had deserted their country and fled across the Rhone, where, joined by the tribes dwelling upon the further bank, they prepared to offer a desperate opposition to the passage of the river. The appearance of this mass of barbarians, armed with bows and arrows and javelins, on the further side of the wide and rapid river which had to be crossed, was not encouraging.
“It was bad enough crossing the Pyrenees,” Malchus said to Trebon, “but that was nothing to this undertaking; it is one thing to climb a precipice, however steep, to the assault of an enemy, another to swim across at the head of the army under such a shower of missiles as we shall meet with on the other side.”
Hannibal, however, had prepared to overcome the difficulty. Messengers had been sent up and down the river to all the people living on the right bank, offering to buy from them at good prices every barge and boat in their possession, promising them freedom from all exactions and hard treatment, and offering good pay to those who would render assistance to the army in the passage. Hannibal's offers were accepted without hesitation. That the army, which could, had it chosen, have taken all their boats by force and impressed their labour, should offer to pay liberally for both, filled them with admiration, and they were, moreover, only too glad to aid this formidable army of strangers to pass out of their country.
The dwellers upon the Rhone at this period carried on an extensive commerce, not only with the tribes of the upper river, but with Marseilles and the ports of Spain and Northern Italy, consequently a large number of vessels and barges of considerable tonnage were at once obtained.
To add to the means of transport the whole army were set to work, and, assisted by the natives, the soldiers cut down trees, and, hollowing them out roughly, formed canoes capable of carrying two or three men. So industriously did the troops work that in two days enough canoes were made to carry the army across the river; but there was still the opposition of the natives to be overcome, and when the canoes were finished Hannibal ordered Hanno, one of his best generals, to start with a division at nightfall up the bank of the river.
Hanno marched five miles, when he found a spot where the river was smooth and favourable for the passage. The troops set to at once to cut trees; rafts were formed of these, and the troops passed over. The Spanish corps, accustomed to the passage of rivers, simply stripped, and putting their broad shields of hides beneath them, passed the river by swimming. Once across Hanno gave his men twenty-four hours' rest, and then, calculating that Hannibal's preparations would be complete, he marched down the river until he reached a hill, whose summit was visible from Hannibal's camp at daybreak. Upon this he lit a signal fire.
The moment the smoke was seen in the camp Hannibal gave orders for the troops to embark. The light infantry took to their little canoes, the cavalry embarked in the larger vessels, and, as these were insufficient to carry all the horses, a great many of the animals were made to enter the river attached by ropes to the vessels. The heavier craft started highest up, in order that they might to some extent break the roughness of the waves and facilitate the passage of the canoes.
The din was prodigious. Thousands of men tugged at the oars, the roughly made canoes were dashed against each other and often upset, while from the opposite bank rose loudly the defiant yells of the natives, prepared to dispute to the last the landing of the flotilla. Suddenly these cries assumed a different character. A mass of smoke was seen to rise from the tents of the enemy's camp, and Hanno's division poured down upon their rear. The Arecomici, taken wholly by surprise, were seized with a panic, and fled hastily in all directions, leaving the bank clear for the landing of Hannibal. The whole of the army were brought across at once and encamped that night on the river.
In the morning Hannibal sent off five hundred Numidian horse to reconnoitre the river below, and ascertain what Scipio's army, which was known to have landed at its mouth, was doing. He then assembled his army and introduced to them some chiefs of the tribes beyond the Alps, who had a day or two before arrived in the camp with the agents he had sent to their country. They harangued the soldiers, an interpreter translating their speeches, and assured them of the welcome they would meet in the rich and fertile country beyond the Alps, and of the alacrity with which the people there would join them against the Romans.
Hannibal himself then addressed the soldiers, pointed out to them that they had already accomplished by far the greatest part of their journey, had overcome every obstacle, and that there now remained but a few days' passage over the mountains, and that Italy, the goal of all their endeavours, would then lie before them.
The soldiers replied with enthusiastic shouts, and Hannibal, after offering up prayers to the gods on behalf of the army, dismissed the soldiers, and told them to prepare to start on the following day. Soon after the assembly had broken up the Numidian horse returned in great confusion, closely pressed by the Roman cavalry, who had been sent by Scipio to ascertain Hannibal's position and course. The hostile cavalry had charged each other with fury. A hundred and forty of the Romans and two hundred of the Numidians were slain.
Hannibal saw that there was no time to be lost. The next morning, at daybreak, the whole of his cavalry were posted to the south to cover the movements of the army and to check the Roman advance. The infantry were then set in motion up the bank of the river and Hannibal, with a small party, remained behind to watch the passage of the elephants, which had not yet been brought across.
The elephants had not been trained to take to the water, and the operation was an extremely difficult one. Very strong and massive rafts were joined together until they extended two hundred feet into the river, being kept in their place by cables fastened to trees on the bank above them. At the end of this floating pier was placed another raft of immense size, capable of carrying four elephants at a time. A thick covering of earth was laid over the whole, and on this turf was placed. The elephants were then led forward.
So solid was the construction that they advanced upon it without hesitation. When four had taken their place on the great raft at the end, the fastenings which secured it to the rest of the structure were cut, and a large number of boats and barges filled with rowers began to tow the raft across the river. The elephants were seized with terror at finding themselves afloat, but seeing no way of escape remained trembling in the centre of the raft until they reached the other side. When it was safely across, the raft and towing boats returned, and the operation was repeated until all the elephants were over.
Some of the animals, however, were so terrified that they flung themselves from the rafts into the river and made their way to shore, keeping their probosces above the surface of the water. The Indians who directed them were, however, all swept away and drowned. As soon as the elephants were all across Hannibal called in his cavalry, and with them and the elephants followed the army.
The Romans did not arrive at the spot until three days after the Carthaginians had left. Scipio was greatly astonished when he found that Hannibal had marched north, as he believed that the Alps were impassable for an army, and had reckoned that Hannibal would certainly march down the river and follow the seashore. Finding that the Carthaginians had left he marched his army down to his ships again, re-embarked them, and sailed for Genoa, intending to oppose Hannibal as he issued from the defiles of the Alps, in the event of his succeeding in making the passage.
Four days' march up the Rhone brought Hannibal to the point where the Isere runs into that river. He crossed it, and with his army entered the region called by Polybius “The Island,” although the designation is an incorrect one, for while the Rhone flows along one side of the triangle and the Isere on the other, the base is formed not by a third river, but by a portion of the Alpine chain.
Malchus and his band had been among the first to push off from the shore when the army began to cross the Rhone. Malchus was in a roughly constructed canoe, which was paddled by Nessus and another of his men. Like most of the other canoes, their craft soon became waterlogged, for the rapid and angry current of the river, broken and agitated by so large a number of boats, splashed over the sides of the clumsy canoes, which were but a few inches above the water. The buoyancy of the wood was sufficient to float them even when full, but they paddled slowly and heavily.
The confusion was prodigious. The greater part of the men, unaccustomed to rowing, had little control over their boats. Collisions were frequent, and numbers of the boats were upset and their occupants drowned. The canoe which carried Malchus was making fair progress, but, to his vexation, was no longer in the front line. He was urging the paddlers to exert themselves to the utmost, when Nessus gave a sudden cry.
A horse which had broken loose from its fastenings behind one of the barges was swimming down, frightened and confused at the din. It was within a few feet of them when Nessus perceived it, and in another moment it struck the canoe broadside with its chest. The boat rolled over at once, throwing its occupants into the water. Malchus grasped the canoe as it upset, for he would instantly have sunk from the weight of his armour. Nessus a moment later appeared by his side.
“I will go to the other side, my lord,” he said, “that will keep the tree from turning over again.”
He dived under the canoe, and came up on the opposite side, and giving Malchus his hand across it, there was no longer any fear of the log rolling over. The other rower did not reappear above the surface. Malchus shouted in vain to some of the passing boats to pick him up, but all were so absorbed in their efforts to advance and their eagerness to engage the enemy that none paid attention to Malchus or the others in like plight. Besides, it seemed probable that all, if they stuck to their canoes, would presently gain one bank or other of the river. Malchus, too, had started rather low down, and he was therefore soon out of the flotilla.
The boat was nearly in midstream when the accident happened.
“The first thing to do,” Malchus said when he saw that there was no chance of their being picked up, “is to rid myself of my armour. I can do nothing with it on, and if the tree turns over I shall go down like a stone. First of all, Nessus, do you unloose your sword belt. I will do the same. If we faste............
