Psara was the third most powerful naval force in Greece, after Hydra and Spetses, and the birthplace of great fire starters, which severely damaged the Turkish fleet. The Ottoman fleet, under Hüsrev Mehmed Pasha, landed in Psara on June 20, 1824. The defense of the people of Psara was not well organized, so the island fell relatively quickly. Massive destruction and massacres followed. Out of the 30,000 inhabitants, 18,000 were killed or captured.
