News of the danger facing Kasos arrived at Hydra on the 21st, and the Greek fleet mobilized with much delay and difficulty, not arriving before the island until 2 July. The agha left as governor by Ismael Gibraltar fled the island to Karpathos, but the island was entirely destroyed; Vice Admiral Georgios Sachtouris and his captains proposed to the islanders to transport them to the Peloponnese, but the Kasiots refused, and the Greek fleet, receiving news that the main Ottoman fleet had set sail from Constantinople, was forced to leave the island.[15][16] Indeed, the destruction of Kasos was followed soon after by another, heavier blow for the Greeks: the Destruction of Psara.[17][18]
