2. If the Lacedaemonians or their allies should require any assistance from the King, or the King from the Lacedaemonians or their allies, whatever they both agree upon they shall be right in doing.

3. Both shall carry on jointly the war against the Athenians and their allies: and if they make peace, both shall do so jointly.

4. The expense of all troops in the King’s country, sent for by the King, shall be borne by the King.

5. If any of the states comprised in this convention with the King attack the King’s country, the rest shall stop them and aid the King to the best of their power. And if any in the King’s country or in the countries under the King’s rule attack the country of the Lacedaemonians or their allies, the King shall stop it and help them to the best of his power.

After this convention Therimenes handed over the fleet to Astyochus, sailed off in a small boat, and was lost. The Athenian armament had now crossed over from Lesbos to Chios, and being master by sea and land began to fortify Delphinium, a place naturally strong on the land side, provided with more than one harbour, and also not far from the city of Chios. Meanwhile the Chians remained inactive. Already defeated in so many battles, they were now also at discord among themselves; the execution of the party of Tydeus, son of Ion, by Pedaritus upon the charge of Atticism, followed by the forcible imposition of an oligarchy upon the rest of the city, having made them suspicious of one another; and they therefore thought neither themselves not the mercenaries under Pedaritus a match for the enemy. They sent, however, to Miletus to beg Astyochus to assist them, which he refused to do, and was accordingly denounced at Lacedaemon by Pedaritus as a traitor. Such was the state of the Athenian affairs at Chios; while their fleet at Samos kept sailing out against the enemy in Miletus, until they found that he would not accept their challenge, and then retired again to Samos and remained quiet.

In the same winter the twenty-seven ships equipped by the Lacedaemonians for Pharnabazus through the agency of the Megarian Calligeitus, and the Cyzicene Timagoras, put out from Peloponnese and sailed for Ionia about the time of the solstice, under the command of Antisthenes, a Spartan. With them the Lacedaemonians also sent eleven Spartans as advisers to Astyochus; Lichas, son of Arcesilaus, being among the number. Arrived at Miletus, their orders were to aid in generally superintending the good conduct of the war; to send off the above ships or a greater or less number to the Hellespont to Pharnabazus, if they thought proper, appointing Clearchus, son of Ramphias, who sailed with them, to the command; and further, if they thought proper, to make Antisthenes admiral, dismissing Astyochus, whom the letters of Pedaritus had caused to be regarded with suspicion. Sailing accordingly from Malea across the open sea, the squadron touched at Melos and there fell in with ten Athenian ships, three of which they took empty and burned. After this, being afraid that the Athenian vessels escaped from Melos might, as they in fact did, give information of their approach to the Athenians at Samos, they sailed to Crete, and having lengthened their voyage by way of precaution made land at Caunus in Asia, from whence considering themselves in safety they sent a message to the fleet at Miletus for a convoy along the coast.

Meanwhile the Chians and Pedaritus, undeterred by the backwardness of Astyochus, went on sending messengers pressing him to come with all the fleet to assist them against their besiegers, and not to leave the greatest of the allied states in Ionia to be shut up by sea and overrun and pillaged by land. There were more slaves at Chios than in any one other city except Lacedaemon, and being also by reason of their numbers punished more rigorously when they offended, most of them, when they saw the Athenian armament firmly established in the island with a fortified position, immediately deserted to the enemy, and through their knowledge of the country did the greatest mischief. The Chians therefore urged upon Astyochus that it was his duty to assist them, while there was still a hope and a possibility of stopping the enemy’s progress, while Delphinium was still in process of fortification and unfinished, and before the completion of a higher rampart which was being added to protect the camp and fleet of their besiegers. Astyochus now saw that the allies also wished it and prepared to go, in spite of his intention to the contrary owing to the threat already referred to.

In the meantime news came from Caunus of the arrival of the twenty-seven ships with the Lacedaemonian commissioners; and Astyochus, postponing everything to the duty of convoying a fleet of that importance, in order to be more able to command the sea, and to the safe conduct of the Lacedaemonians sent as spies over his behaviour, at once gave up going to Chios and set sail for Caunus. As he coasted along he landed at the Meropid Cos and sacked the city, which was unfortified and had been lately laid in ruins by an earthquake, by far the greatest in living memory, and, as the inhabitants had fled to the mountains, overran the country and made booty of all it contained, letting go, however, the free men. From Cos arriving in the night at Cnidus he was constrained by the representations of the Cnidians not to disembark the sailors, but to sail as he was straight against the twenty Athenian vessels, which with Charminus, one of the commanders at Samos, were on the watch for the very twenty-seven ships from Peloponnese which Astyochus was himself sailing to join; the Athenians in Samos having heard from Melos of their approach, and Charminus being on the look-out off Syme, Chalce, Rhodes, and Lycia, as he now heard that they were at Caunus.

Astyochus accordingly sailed as he was to Syme, before he was heard of, in the hope of catching the enemy somewhere out at sea. Rain, however, and foggy weather encountered him, and caused his ships to straggle and get into disorder in the dark. In the morning his fleet had parted company and was most of it still straggling round the island, and the left wing only in sight of Charminus and the Athenians, who took it for the squadron which they were watching for from Caunus, and hastily put out against it with part only of their twenty vessels, and attacking immediately sank three ships and disabled others, and had the advantage in the action until the main body of the fleet unexpectedly hove in sight, when they were surrounded on every side. Upon this they took to flight, and after losing six ships with the rest escaped to Teutlussa or Beet Island, and from thence to Halicarnassus. After this the Peloponnesians put into Cnidus and, being joined by the twenty-seven ships from Caunus, sailed all together and set up a trophy in Syme, and then returned to anchor at Cnidus.

As soon as the Athenians knew of the sea-fight, they sailed with all the ships at Samos to Syme, and, without attacking or being attacked by the fleet at Cnidus, took the ships’ tackle left at Syme, and touching at Lorymi on the mainland sailed back to Samos. Meanwhile the Peloponnesian ships, being now all at Cnidus, underwent such repairs as were needed; while the eleven Lacedaemonian commissioners conferred with Tissaphernes, who had come to meet them, upon the points which did not satisfy them in the past transactions, and upon the best and mutually most advantageous manner of conducting the war in future. The severest critic of the present proceedings was Lichas, who said that neither of the treaties could stand, neither that of Chalcideus, nor that of Therimenes; it being monstrous that the King should at this date pretend to the possession of all the country formerly ruled by himself or by his ancestors—a pretension which implicitly put back under the yoke all the islands—Thessaly, Locris, and everything as far as Boeotia—and made the Lacedaemonians give to the Hellenes instead of liberty a Median master. He therefore invited Tissaphernes to conclude another and a better treaty, as they certainly would not recognize those existing and did not want any of his pay upon such conditions. This offended Tissaphernes so much that he went away in a rage without settling anything.
