The Athenians were now in a desperate situation. On September 3, the Syracusans began to completely blockade the entrance to the port, trapping the Athenians inside. Outside Syracuse, the Athenians built a smaller walled enclosure for their sick and injured, and put everyone else (including many of the soldiers remaining on land) on their ships for one last battle, on September 9. The fleet was now commanded by Demosthenes, Menander, and Euthydemus, while the Syracusan fleet was led by Sicanus and Agatharchus of Syracuse on the wings and Pythen from Corinth in the centre. Each side had about 100 ships participating.
