But about thirty days after, Alcibiades escaped from his keeping, and having got a horse, fled to Clazomenae, where he procured Tisaphernes additional disgrace by professing he was a party to his escape. From there he sailed to the Athenian camp, and, being informed there that Mindarus and Pharnabazus were together at Cyzicus, he made a speech to the soldiers, telling them that sea-fighting, land-fighting, and, by the gods, fighting against fortified cities too, must be all one for them, as unless they conquered everywhere, there was no money for them. As soon as ever he got them on shipboard, he hastened to Proconnesus, and gave command to seize all the small vessels they met, and guard them safely in the interior of the fleet, that the enemy might have no notice of his coming; and a great storm of rain, accompanied with thunder and darkness, which happened at the same time, contributed much to the concealment of his enterprise. Indeed, it was not only undiscovered by the enemy, but the Athenians themselves were ignorant of it, for he commanded them suddenly on board, and set sail when they had abandoned all intention of it. As the darkness presently passed away, the Peloponnesian fleet was seen riding out at sea in front of the harbour of Cyzicus. Fearing, if they discovered the number of his ships, they might endeavour to save themselves by land, he commanded the rest of the captains to slacken, and follow him slowly, whilst he, advancing with forty ships, showed himself to the enemy, and provoked them to fight. The enemy, being deceived as to their numbers, despised them, and, supposing they were to contend with those only, made themselves ready and began the fight. But as soon as they were engaged, they perceived the other part of the fleet coming down upon them, at which they were so terrified that they fled immediately. Upon that, Alcibiades, breaking through the midst of them with twenty of his best ships, hastened to the shore, disembarked, and pursued those who abandoned their ships and fled to land, and made a great slaughter of them. Mindarus and Pharnabazus, coming to their succour, were utterly defeated. Mindarus was slain upon the place, fighting valiantly; Pharnabazus saved himself by flight. The Athenians slew great numbers of their enemies, won much spoil, and took all their ships. They also made themselves masters of Cyzicus which was deserted by Pharnabazus, and destroyed its Peloponnesian garrison, and thereby not only secured to themselves the Hellespont, but by force drove the Lacedaemonians from out of the rest of the sea. They intercepted some letters written to the ephors, which gave an account of this fatal overthrow, after their short laconic manner.
"Our hopes are at an end. Mindarus is slain. The men starve. We know not what to do."The soldiers who followed Alcibiades in this last fight were so exalted with their success, and felt that degree of pride, that, looking on themselves as invincible, they disdained to mix with the other soldiers, who had been often overcome. For it happened not long before, Thrasyllus had received a defeat near Ephesus, and, upon that occasion, the Ephesians erected their brazen trophy to the disgrace of the Athenians. The soldiers of Alcibiades reproached those who were under the command of Thrasyllus with this misfortune, at the same time magnifying themselves and their own commander, and it went so far that they would not exercise with them, nor lodge in the same quarters. But soon after, Pharnabazus, with a great force of horse and foot, falling upon the soldiers of Thrasyllus, as they were laying waste the territory of Abydos, Alcibiades came to their aid, routed Pharnabazus, and together with Thrasyllus pursued him till it was night; and in this action the troops united, and returned together to the camp, rejoicing and congratulating one another. The next day he erected a trophy, and then proceeded to lay waste with fire and sword the whole province which was under Pharnabazus, where none ventured to resist; and he took divers priests and priestesses, but released them without ransom. He prepared next to attack the Chalcedonians, who had revolted from the Athenians, and had received a Lacedaemonian governor and garrison. But having intelligence that they had removed their corn and cattle out of the fields, and were conveying it all to the Bithynians, who were their friends, he drew down his army to the frontier of the Bithynians, and then sent a herald to charge them with this proceeding. The Bithynians, terrified at his approach, delivered up to him the booty, and entered into alliance with him.
Afterwards he proceeded to the siege of Chalcedon, and enclosed it with a wall from sea to sea. Pharnabazus advanced with his forces to raise the siege, and Hypocrites, the governor of the town, at the same time, gathering together all the strength he had, made a sally upon the Athenians. Alcibiades divided his army so as to engage both at once, and not only forced Pharnabazus to a dishonourable flight, but defeated Hypocrites, and killed him and a number of the soldiers with him. After this he sailed into the Hellespont, in order to raise supplies of money, and took the city of Selymbria, in which action, through his precipitation, he exposed himself to great danger.
