When the Syracusans, too, heard this, they were much more stimulated not to relax in their efforts against the Athenians, since they themselves had now confessed that they were no longer their superiors, either by sea or by land, (for they would not else have meditated sailing away;) and at the same time, because they did not wish them to go and settle in any other part of Sicily, and so to be more difficult to make war upon;
but were desirous of forcing them to a sea-fight there, as quickly as possible, in a position that was advantageous to themselves. They manned their ships therefore, and practised as many days as they thought sufficient. And when a favourable opportunity presented itself, on the first day they assaulted the Athenian lines; and a small division of their heavy-armed and horse having sallied forth against them through certain gateways, they intercepted some of the heavy-armed, and routed and pursued them back; and as the entrance was narrow, the Athenians lost seventy horses, and some few heavy-armed.
On that day, then, the army of the Syracusans drew off; but on the next they both sailed out with their ships, seventy-six in number, and at the same time advanced with their troops against the walls. The Athenians put out to meet them with eighty-six ships, and closed and fought with them.
Now when Eurymedon, who commanded the right wing of the Athenians, and wished to surround the ships of the enemy, had sailed out from the line too much towards the shore; the Syracusans and their allies, after first defeating the centre of the Athenians, intercepted him also in the bottom and furthest recess of the harbour, and both killed him, and destroyed the ships that were following him. After which the Syracusans closely pursued all the ships of the Athenians, and drove them ashore.
When Gylippus saw the enemy's ships defeated, and carried beyond the stockades and their own station, wishing to cut off the men that were landing from them, and that the Syracusans might more easily tow off the vessels, through the land being in possession of their friends, he ran down to meet them at the break-water with some part of his army.
The Tyrrhenians (for it was they who were keeping guard at this point) seeing them coming on in disorder, advanced towards them, and fell upon and routed their van, and drove them into what was called the marsh of Lysimelea.
Afterwards, when the force of the Syracusans and their allies had now come up in greater numbers, the Athenians also advanced against them, being afraid for their ships, and entered into action with them, and defeated and pursued them to some distance, killing a few heavy-armed. They saved also the greater part of their own ships, and brought them together alongside their station; eighteen of them, however, the Syracusans and their allies captured, and put all the men to the sword.
Wishing also to burn the rest of them, they filled an old merchantman with faggots and pine-wood, and having thrown fire into it, and the wind blowing right on the Athenians, they let the vessel drift towards them. The Athenians, alarmed for their ships, contrived, on the other hand, means for checking and extinguishing it; and having stopped the flames and the near approach of the merchantman, they thus escaped the danger.
After this, the Syracusans erected a trophy, both for their sea-fight, and for the interception of the heavy-armed above, at the wall, where they als took the horses; while the Athenians did the same for the rout of those of the infantry whom the Tyrrhenians drove into the marsh, and for that which they themselves effected with the rest of their army.
