History of the Peloponnesian War by Thucydides — Book VII, Decelea; Plemmyrion lost

In the meantime the Lacedaemonians prepared for their invasion of Attica, in accordance with their own previous resolve, and at the instigation of the Syracusans and Corinthians, who wished for an invasion to arrest the reinforcements which they heard that Athens was about to send to Sicily. Alcibiades also urgently advised the fortification of Decelea, and a vigorous prosecution of the war. ^18.2But the Lacedaemonians derived most encouragement from the belief that Athens, with two wars on her hands, against themselves and against the Siceliots, would be more easy to subdue, and from the conviction that she had been the first to infringe the truce. In the former war, they considered, the offence had been more on their own side, both on account of the entrance of the Thebans into Plataea in time of peace, and also of their own refusal to listen to the Athenian offer of arbitration, in spite of the clause in the former treaty that where arbitration should be offered there should be no appeal to arms. For this reason they thought that they deserved their misfortunes, and took to heart seriously the disaster at Pylos and whatever else had befallen them. ^18.3But when, besides the ravages from Pylos, which went on without any intermission, the thirty Athenian ships came out from Argos and wasted part of Epidaurus, Prasiae, and other places; when upon every dispute that arose as to the interpretation of any doubtful point in the treaty, their own offers of arbitration were always rejected by the Athenians,—the Lacedaemonians at length decided that Athens had now committed the very same offence as they had before done, and had become the guilty party; and they began to be full of ardor for the war. ^18.4They spent this winter in sending round to their allies for iron, and in getting ready the other implements for building their fort; and meanwhile began raising at home, and also by forced requisitions in the rest of Peloponnese, a force to be sent out in the merchantmen to their allies in Sicily. Winter thus ended, and with it the eighteenth year of this war of which Thucydides is the historian.

^19.1In the first days of the spring following, at an earlier period than usual, the Lacedaemonians and their allies invaded Attica, under the command of Agis, son of Archidamus, king of the Lacedaemonians. They began by devastating the parts bordering upon the plain, and next proceeded to fortify Decelea, dividing the work among the different cities. ^19.2Decelea is about thirteen or fourteen miles from the city of Athens, and the same distance or not much further from Boeotia; and the fort was meant to annoy the plain and the richest parts of the country, being in sight of Athens. ^19.3While the Peloponnesians and their allies in Attica were engaged in the work of fortification, their countrymen at home sent off, at about the same time, the heavy infantry in the merchant vessels to Sicily; the Lacedaemonians furnishing a picked force of Helots and Neodamodes ‘or freedmen), six hundred heavy infantry in all, under the command of Eccritus, a Spartan; and the Boeotians three hundred heavy infantry, commanded by two Thebans, Xenon and Nicon, and by Hegesander, a Thespian. ^19.4These were among the first to put out into the open sea, starting from Taenarus in Laconia. Not long after their departure the Corinthians sent off a force of five hundred heavy infantry, consisting partly of men from Corinth itself, and partly of Arcadian mercenaries, placed under the command of Alexarchus, a Corinthian. The Sicyonians also sent off two hundred heavy infantry at the same time as the Corinthians, under the command of Sargeus, a Sicyonian. ^19.5Meantime the five-and-twenty vessels manned by Corinth during the winter, lay confronting the twenty Athenian ships at Naupactus until the heavy infantry in the merchantmen were fairly on their way from Peloponnese; thus fulfilling the object for which they had been manned originally, which was to divert the attention of the Athenians from the merchantmen to the galleys.

^20.1During this time the Athenians were not idle. Simultaneously with the fortification of Decelea, at the very beginning of spring, they sent thirty ships round Peloponnese, under Charicles, son of Apollodorus, with instructions to call at Argos and demand a force of their heavy infantry for the fleet, agreeably to the alliance. At the same time they despatched Demosthenes to Sicily, ^20.2as they had intended, with sixty Athenian and five Chian vessels, twelve hundred Athenian heavy infantry from the muster-roll, and as many of the islanders as could be raised in the different quarters, drawing upon the other subject allies for whatever they could supply that would be of use for the war. Demosthenes was instructed first to sail round with Charicles and to operate with him upon the coasts of Laconia, ^20.3and accordingly sailed to Aegina and there waited for the remainder of his armament, and for Charicles to fetch the Argive troops.

^21.1In Sicily about the same time in this spring, Gylippus came to Syracuse with as many troops as he could bring from the cities which he had persuaded to join. ^21.2Calling the Syracusans together, he told them that they must man as many ships as possible, and try their hand at a sea-fight, by which he hoped to achieve an advantage in the war not unworthy of the risk. ^21.3With him Hermocrates actively joined in trying to encourage his countrymen to attack the Athenians at sea, saying that the latter had not inherited their naval prowess nor would they retain it for ever; they had been landsmen even to a greater degree than the Syracusans, and had only become a maritime power when obliged by the Mede. Besides, to daring spirits like the Athenians, a daring adversary would seem the most formidable; and the Athenian plan of paralyzing by the boldness of their attack a neighbor often not their inferior in strength, could now be used against them with as good effect by the Syracusans. ^21.4He was convinced also that the unlooked-for spectacle of Syracusans daring to face the Athenian navy would cause a terror to the enemy, the advantages of which would far outweigh any loss that Athenian science might inflict upon their inexperience. He accordingly urged them to throw aside their fears and to try their fortune at sea; ^21.5and the Syracusans, under the influence of Gylippus and Hermocrates, and perhaps some others, made up their minds for the sea-fight and began to man their vessels.

^22.1When the fleet was ready, Gylippus led out the whole army by night; his plan being to assault in person the forts of Plemmyrium by land, while thirty-five Syracusan galleys sailed according to appointment against the enemy from the great harbor, and the forty-five remaining came round from the lesser harbor, where they had their arsenal, in order to effect a junction with those inside and simultaneously to attack Plemmyrium, and thus to distract the Athenians by assaulting them on two sides at once. ^22.2The Athenians quickly manned sixty ships, and with twenty-five of these engaged the thirty-five of the Syracusans in the great harbor, sending the rest to meet those sailing round from the arsenal; and an action now ensued directly in front of the mouth of the great harbor, maintained with equal tenacity on both sides; the one wishing to force the passage, the other to prevent them.

^23.1In the meantime, while the Athenians in Plemmyrium were down at the sea, attending to the engagement, Gylippus made a sudden attack on the forts in the early morning and took the largest first, and afterwards the two smaller, whose garrisons did not wait for him, seeing the largest so easily taken. ^23.2At the fall of the first fort, the men from it who succeeded in taking refuge in their boats and merchantmen, found great difficulty in reaching the camp, as the Syracusans were having the best of it in the engagement in the great harbor, and sent a fast sailing galley to pursue them. But when the two others fell, the Syracusans were now being defeated; and the fugitives from these sailed along shore with more ease. ^23.3The Syracusan ships fighting off the mouth of the harbor, forced their way through the Athenian vessels and sailing in without any order fell foul of one another, and transferred the victory to the Athenians; who not only routed the squadron in question, but also that by which they were at first being defeated in the harbor, ^23.4sinking eleven of the Syracusan vessels and killing most of the men, except the crews of three ships whom they made prisoners. Their own loss was confined to three vessels; and after hauling ashore the Syracusan wrecks and setting up a trophy upon the islet in front of Plemmyrium, they retired to their own camp.

^24.1Unsuccessful at sea, the Syracusans had nevertheless the forts in Plemmyrium, for which they set up three trophies. One of the two last taken they razed, but put in order and garrisoned the two others. ^24.2In the capture of the forts a great many men were killed and made prisoners, and a great quantity of property was taken in all. As the Athenians had used them as a magazine, there was a large stock of goods and corn of the merchants inside, and also a large stock belonging to the captains; the masts and other furniture of forty galleys being taken, besides three galleys which had been drawn up on shore. ^24.3Indeed the first and chiefest cause of the ruin of the Athenian army was the capture of Plemmyrium; even the entrance of the harbor being now no longer safe for carrying in provisions, as the Syracusan vessels were stationed there to prevent it, and nothing could be brought in without fighting; besides the general impression of dismay and discouragement produced upon the army.

^25.1After this the Syracusans sent out twelve ships under the command of Agatharchus, a Syracusan. One of these went to Peloponnese with ambassadors to describe the hopeful state of their affairs, and to incite the Peloponnesians to prosecute the war there even more actively than they were now doing, while the eleven others sailed to Italy, hearing that vessels laden with stores were on their way to the Athenians. ^25.2After falling in with and destroying most of the vessels in question, and burning in the Caulonian territory a quantity of timber for shipbuilding, which had been got ready for the Athenians, ^25.3the Syracusan squadron went to Locri, and one of the merchantmen from Peloponnese coming in, while they were at anchor there, carrying Thespian heavy infantry, ^25.4took these on board and sailed along shore towards home. The Athenians were on the look-out for them with twenty ships at Megara, but were only able to take one vessel with its crew; the rest getting clear off to Syracuse. ^25.5There was also some skirmishing in the harbor about the piles which the Syracusans had driven in the sea in front of the old docks, to allow their ships to lie at anchor inside, without being hurt by the Athenians sailing up and running them down. ^25.6The Athenians brought up to them a ship of ten thousand talents' burden furnished with wooden turrets and screens, and fastened ropes round the piles from their boats, wrenched them up and broke them, or dived down and sawed them in two. Meanwhile the Syracusans plied them with missiles from the docks, to which they replied from their large vessel; until at last most of the piles were removed by the Athenians. ^25.7But the most awkward part of the stockade was the part out of sight: some of the piles which had been driven in did not appear above water, so that it was dangerous to sail up, for fear of running the ships upon them, just as upon a reef, through not seeing them. However divers went down and sawed off even these for reward; although the Syracusans drove in others. ^25.8Indeed there was no end to the contrivances to which they resorted against each other, as might be expected between two hostile armies confronting each other at such a short distance: and skirmishes and all kinds of other attempts were of constant occurrence. ^25.9Meanwhile the Syracusans sent embassies to the cities composed of Corinthians, Ambraciots, and Lacedaemonians, to tell them of the capture of Plemmyrium, and that their defeat in the sea-fight was due less to the strength of the enemy than to their own disorder; and generally, to let them know that they were full of hope, and to desire them to come to their help with ships and troops, as the Athenians were expected with a fresh army, and if the one already there could be destroyed before the other arrived, the war would be at an end.

^26.1While the contending parties in Sicily were thus engaged, Demosthenes, having now got together the armament with which he was to go to the island, put out from Aegina, and making sail for Peloponnese, joined Charicles and the thirty ships of the Athenians. Taking on board the heavy infantry from Argos they sailed to Laconia, ^26.2and after first plundering part of Epidarus Limera, landed on the coast of Laconia, opposite Cythera, where the temple of Apollo stands, and laying waste part of the country, fortified a sort of isthmus, to which the Helots of the Lacedaemonians might desert, and from whence plundering incursions might be made as from Pylos. ^26.3Demosthenes helped to occupy this place, and then immediately sailed on to Corcyra to take up some of the allies in that island, and so to proceed without delay to Sicily; while Charicles waited until he had completed the fortification of the place, and leaving a garrison there, returned home subsequently with his thirty ships and the Argives also.
