Two accounts of the battle of Aegospotami exist. Diodorus Siculus relates that the Athenian general in command on the fifth day at Sestos, Philocles, sailed out with thirty ships, ordering the rest to follow him. Donald Kagan has argued that the Athenian strategy, if this account is accurate, must have been to draw the Peloponnesians into an attack on the small force so that the larger force following could surprise them. In the event, the small force was immediately defeated, and the remainder of the fleet was caught unprepared on the beach.
