For a short time a terrible panic reigned among the Carthaginians, great numbers were cut down, and it seemed as if the whole force would be destroyed. Hannibal and his generals rode about trying to get the scattered men to form and oppose the enemy; but the panic was too general, and had it not been for the Carthaginian legion all would have been lost. The horse and foot, however, of this body, having abstained from joining in the pillage, had, for the most part, kept together in bodies, and these now sallied out in close and regular order, and fell upon the attacking enemy.
The streets were too narrow for cavalry to act, and Malchus and his comrades fought on foot. The enemy, who had scattered on their work of slaughter, were in their turn taken at a disadvantage, and were unable to withstand the steady attack of the solid bodies. These, in the first place, cut their way to the square in the centre of the town, and there united. Hannibal, seeing he had now a solid body of troops under his command, at once broke them up into parties and advanced down all the streets leading from the central square. The hand-to-hand fight which was going on all over the town was soon terminated. The Carthaginians fell in in good order behind the ranks of their comrades, and the small bodies soon became columns which swept the enemy before them.
The enemy fought desperately, firing the houses, hurling stones from the roofs upon the columns, and throwing themselves with reckless bravery upon the spears, but their efforts were in vain. Foot by foot they were driven back, until they were again expelled from the town. Keeping together, and ever showing front to the Carthaginians, the Vacaei, now reduced to less than half their number, retired to an eminence near the town, and there prepared to sell their lives dearly. The Carthaginians now fell into their regular ranks, and prepared to storm the enemy's position; but Hannibal rode forward alone towards the Vacaei, being plainly visible to them in the broad blaze of light from the burning city.
From his long residence in Spain he was able to speak the Iberian tongue with fluency, and indeed could converse with all the troops of the various nationalities under the banner of Carthage in their own language.
“Men of Salamanca,” he said, “resist no longer. Carthage knows how to honour a brave enemy, and never did men fight more valiantly in defence of their homes than you have done, and although further resistance would be hopeless, I will press you no further. Your lives are spared. You may retain the arms you know so well how to wield, and tomorrow my army will evacuate your town and leave you free to return to it.”
Hannibal's clemency was politic. He would have lost many more men before he finally overcame the desperate band, and he was by no means desirous of exciting a deep feeling of hate among any of the tribes, just as he was meditating withdrawing the greater portion of the army for his enterprise against Rome. With the fall of Salamanca the resistance of the Vacaei ceased, and Hannibal prepared to march back to Carthagena.
A storm, however, had gathered in his rear. Great numbers of the Vacaei had sought refuge among the Olcades, who had been subdued the previous autumn, and together they had included the whole of the fierce tribes known as the Carpatans, who inhabited the country on the right bank of the upper Tagus, to make common cause with them against the invaders. As Hannibal approached their neighbourhood they took up their position on the right bank of the river near Toledo. Here the stream is rapid and difficult of passage, its bed being thickly studded with great boulders brought down in time of flood from the mountains. The country on each side of the river is sandy, free from forests or valleys, which would cover the movements of an army.
The host gathered to oppose the Carthaginians were fully one hundred thousand strong, and Hannibal saw at once that his force, weakened as it was with its loss at Salamanca, and encumbered by the great train laden with the booty they had gathered from the Vacaei, would have no chance whatever in a battle with so vast a body. The enemy separated as he approached the river, their object being evidently to fall upon his rear when engaged in the difficult operation of crossing. The Carthaginians moved in two heavy columns, one on each side of their baggage, and Hannibal's orders were stringent that on no account should they engage with the enemy.
The natives swarmed around the columns, hurling darts and javelins; but the Carthaginians moved forward in solid order, replying only with their arrows and slings, and contenting themselves with beating off the attacks which the bolder of their foes made upon them. Night was falling when they arrived on the bank of the river. The enemy then desisted from their attack, believing that in the morning the Carthaginians would be at their mercy, encumbered by their vast booty on one side and cut off from retreat by a well nigh impassable river on the other.
As soon as the army reached the river Hannibal caused the tents of all the officers to be erected. The baggage wagons were arranged in order, and the cattle unharnessed. The troops began to throw up intrenchments, and all seemed to show that the Carthaginians were determined to fight till the last on the ground they held. It was still light enough for the enemy to perceive what was being done, and, secure of their prey in the morning, they drew off to a short distance for the night. Hannibal had learned from a native that morning of a ford across the river, and it was towards this that he had been marching. As soon as it was perfectly dark a number of men entered the river to search for the ford. This was soon discovered.
