The besiegers were thus condemned to stay in the country; and the Syracusans, getting wind of what had happened, became more eager than ever to press the Athenians, who had now themselves acknowledged that they were no longer their superiors either by sea or by land, as otherwise they would never have planned to sail away. Besides which the Syracusans did not wish them to settle in any other part of Sicily, where they would be more difficult to deal with, but desired to force them to fight at sea as quickly as possible, in a position favourable to themselves. Accordingly they manned their ships and practised for as many days as they thought sufficient. When the moment arrived they assaulted on the first day the Athenian lines, and upon a small force of heavy infantry and horse sallying out against them by certain gates, cut off some of the former and routed and pursued them to the lines, where, as the entrance was narrow, the Athenians lost seventy horses and some few of the heavy infantry.
Drawing off their troops for this day, on the next the Syracusans went out with a fleet of seventy-six sail, and at the same time advanced with their land forces against the lines. The Athenians put out to meet them with eighty-six ships, came to close quarters, and engaged. The Syracusans and their allies first defeated the Athenian centre, and then caught Eurymedon, the commander of the right wing, who was sailing out from the line more towards the land in order to surround the enemy, in the hollow and recess of the harbour, and killed him and destroyed the ships accompanying him; after which they now chased the whole Athenian fleet before them and drove them ashore.
