The Egyptian-Athenian victory is short-lived: the Persians, led by Megabyzus, the new satrap of Syria, together with Artabazus, satrap of Phrygia, who arrive in 456 BCE, now counterattack, confronting the Athenian fleet blockading Memphis, destroying two squadrons and confining the remainder of the Greek fleet, along with the Egyptian rebels, to an island in the Nile, where the Persians besiege them.
Charitimides is killed and Inarus is wounded in the thigh by the Persian force; he retreats to Byblus, his stronghold and the only Egyptian city that does not submit to Megabyzus.
