Plutarch's version by itself already shows, to my opinion, a few inconsistencies, but when we try to mix it with the material I am posting today we will be ready to make questions and find answers.
Let us thus see what Diodorus Siculus tells in his «Bibliotheca Historica» XVI, 18-19:
After this Dionysius dispatched to Syracuse as general Nypsius the Neapolitan, a man who excelled in valour and in sagacity of generalship; and with him he sent merchantmen laden with grain and other supplies. Nypsius then set sail from Locri and completed the voyage to Syracuse.In another post I will be glad to show you what I found odd by comparing the stories I quoted. Wishing to have tickled your curiosity, I invite you all to that date.
The tyrant's mercenaries, stationed on the acropolis, as their supply of grain failed at this time, were in dire distress for want of supplies, but for a time endured in good spirits their lack of food; then, when human nature succumbed to necessity and they despaired of saving their lives, they came together in an assembly at night and voted to surrender the citadel and themselves to the Syracusans at dawn.
Night was just drawing to a close as the mercenaries sent heralds to the Syracusans to make terms, but, as dawn was just breaking, Nypsius sailed in with his fleet and anchored off Arethusa. Consequently, now that scarcity had suddenly changed into a great abundance of supplies, the general Nypsius, after disembarking his soldiers, held a joint assembly, presented arguments suitable to the occasion and won the support of the men to meet the perils in store. Now the acropolis which was already on the point of being given over to the Syracusans was unexpectedly preserved in the aforesaid manner,
but the Syracusans, manning all their triremes, sailed against the enemy while they were still occupied in unloading the supplies. Since the attack was unexpected and the mercenaries in the citadel could only be drawn up in confused fashion against the enemy triremes, a naval battle took place in which the Syracusans had the superiority, in fact they sank some of the ships, gained possession of others, and pursued the remnant to the shore.
Elated by their success they offered magnificent sacrifice to the gods in honour of the victory, and, turning to banqueting and drink, with contempt for the men they had defeated, were negligent about their guards.
Nypsius, the commander of the mercenaries, wishing to renew the battle and retrieve the defeat, with his army which had been marshalled during the night unexpectedly attacked the wall which had been constructed. And, finding that the guards through contempt and drunkenness had betaken themselves to sleep, he placed against it the ladders that had been constructed in case they were needed.
The bravest of the mercenaries climbed on the wall with these, slaughtered the guards, and opened the gates. As the men poured into the city, the generals of the Syracusans, becoming sober after their drunkenness, tried to bring aid, but, their efforts being hampered by the wine, some were slain and some fled. When the city had been captured and almost all the soldiers from the citadel had rushed inside the circuit-walls, since the Syracusans were panic-stricken by the suddenness and confusion of the attack, a great slaughter took place.
The soldiers of the tyrant numbered more than ten thousand and their lines were so well marshalled that no one was able to withstand their sheer weight, inasmuch as the din and disorder and, furthermore, the lack of a commander, impeded the Syracusans in their hour of defeat.
Once the market-place had come into possession of the enemy, the victors straightway attacked the residences. They carried off much property and took off as slaves many women and children and household servants besides. Where the Syracusans formed to meet them in narrow alleys and other streets, continuous engagements occurred and many were killed and not a few wounded. So they passed the night slaying one another at random in the darkness, and every quarter teemed with dead.
