The danger that threatened civilisation must have seemed great at the time, though it was probably less than had been the case when the fate of the world, so to speak, had been in suspense on the day of Salamis. But the fears of Sicily, felt also, we may believe, in mainland Greece, were suddenly relieved. Hannibal had accomplished his object. He had exacted a never-to-be-forgotten vengeance for the death of his grandfather, and he wanted no more. Half Sicily was now in the hands of Carthage, and the Greek name was more humbled than it had been within the memory of man. He disbanded his army, and returned, laden with the spoils of war, to Carthage, where he was received with enthusiasm.
But the danger was only postponed. If Hannibal had been satisfied with the results of his campaign, Carthage was not. Its old ambition of dominating Sicily was revived, and for the next four years it made costly and incessant preparations for another invasion of the eastern or Greek portion of the island. Unfortunately the Sicilian Greeks spent the time, not in consolidating their strength, but in intestine strife. The most eminent citizen of Syracuse had made repeated attempts to establish a despotism. He had met with failure and death, but he left behind him a legacy of political hatred that might well have proved fatal to the State.
In 407 the hostile intention of Carthage became known to the Sicilian Greeks. They sent envoys to make a remonstrance, and to suggest a treaty of peace. No answer was given, and the preparations went on with unabated zeal.
In the following year the expedition sailed. Hannibal was again in command, but he shared his power with a young kinsman, Himilco by name. His force, on the most moderate computation, amounted to 120,000 men, with a fleet of 120 ships of war. It was in Agrigentum, to which the frontier of Greek Sicily had now been pushed back, that the storm was first to fall.
Agrigentum was a splendid city, second only to Syracuse in population, and not yielding even to it in magnificence and wealth. No city in the island or even in mainland Greece, Athens only excepted, could boast more stately temples and public buildings. Surrounded by a large and fertile territory, it carried on a profitable trade with the African coast. It could boast of one kind of wealth in which few Greek cities could vie with it—a noble breed of horses, which were seen at least as often in the front at the chariot-races of Olympia as the teams sent from Syracuse or Argos. Only two years before the time of which I am speaking an Agrigentine citizen had won the prize for four-horse chariots, and on his return home had been escorted from the frontier by three hundred private chariots each drawn by two white horses.
Agrigentum was built on a site naturally strong and had been skilfully fortified. It occupied a group, or rather part of a group, of hills which on all sides but one, the south-western, rose precipitously from the plain, so precipitously indeed that attack was impossible. On the north-east, crowning the height of the most lofty hill, was the citadel, approachable by one narrow path only.
While the fortifications were strong and well cared for, they were also adequately garrisoned. Besides a numerous force raised from her own citizens Agrigentum had in her pay eight hundred Campanian mercenaries, who three years before had served under Hannibal, and had thrown up their engagement dissatisfied with their pay. She had also secured the services of fifteen hundred other mercenaries who were under the command of Dexippus, a Spartan soldier of fortune. The citizens were confident in their ability to repel any attack that might be made on them. When Hannibal proposed a treaty of alliance, which, however, would permit Agrigentum to stand neutral in the approaching conflict, it was promptly rejected.
For a while all went well with the defence. Hannibal assaulted the town at the only point where an assault was possible, but accomplished nothing. He even lost his siege train, for the Agrigentines made a sally, captured, and burnt it. He then adopted the alternative plan of constructing a mound which would put the assailants on a level with the walls. The cemetery of Agrigentum was situated outside the walls in the same quarter as that which was the scene of the attack. Indeed, it was only here that there was any level space. Massive tombs of stone, in which reposed the remains of distinguished or wealthy Agrigentines of past days, abounded, and Hannibal, with the national carelessness of all religions other than his own, determined to make use of these materials for his siege work. His workmen had destroyed many of the tombs, and were busy with the most splendid of them all, that of Theron (tyrant of Agrigentum from 488 to 472) when a thunderbolt fell on the spot. This was regarded by the Carthaginians as a manifest token of the divine displeasure. The panic which followed largely increased the fatalities from a disease which now appeared in the camp. Thousands perished, Hannibal himself being one of the victims. It was not till various expiations, one of them a human sacrifice, had been made that Himilco, who now succeeded to the chief command, was able to resume the operations of the siege.
But fortune still seemed to favour the Greek cause. The other Greek cities had been actively employed in raising a relieving force. A Syracusan army, made up by contingents from Gela and Camarina to 30,000 foot and 5,000 horse, reached the Agrigentine territory. Himilco despatched a force of Spaniards and Italians to contest their further advance. After a fierce fight the Carthaginian mercenaries were broken, and compelled to retreat to their camp. Daphnæus of Syracuse, who was in chief command, possibly recollecting the disastrous result of the too vigorous pursuit of the enemy before Selinus, held back his men when they would have followed up the victory. The officers in command at Agrigentum were equally cautious. Their troops were eager to sally out from the gates and fall upon the flying mercenaries as they hurried past in disorder, but the generals absolutely refused their permission, and the opportunity of completely destroying the enemy—so at least the malcontents contended—was lost.
The allies now entered the town amidst general rejoicing. It was not long, however, before a discordant note was heard. Loud complaints were made of the supineness of the Agrigentine generals in allowing the enemy to escape. Some went so far as to suggest that a treasonable understanding existed between the Agrigentine generals and Himilco. A public assembly was hurriedly convened, and the accused generals were put upon their trials. The leader of the contingent from Camarina, Menes by name, ranged himself with the accusers. What evidence was brought against the generals we do not know. It is quite possible that there was nothing worthy of the name, for a Southern mob was ready then, as, indeed, it is now, to take its wildest guesses as truth. Anyhow their defence, whatever it was, availed nothing. Four out of the five were stoned to death, the fifth was allowed to escape in consideration of his youth. At the same time the Spartan Dexippus was severely censured.
