At 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.
The 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,
sinking 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.
Unsuccessful 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.
In 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.
Indeed 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.
After 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.
After 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,
