After sinking seven of the Athenian vessels and disabling many, and taking most of the men prisoners and killing others, the Syracusans retired and set up trophies for both the engagements, being now confident of having a decided superiority by sea, and by no means despairing of equal success by land.
In the meantime, while the Syracusans were preparing for a second attack upon both elements, Demosthenes and Eurymedon arrived with the succors from Athens, consisting of about seventy-three ships, including the foreigners; nearly five thousand heavy infantry, Athenian and allied; a large number of darters, Hellenic and barbarian, and slingers and archers and everything else upon a corresponding scale.
