To avenge the massacre of Chios, 64 ships from Hydra, Psara, and Spetses gathered in Psara at the end of April and formed a fleet, which waited for an opportunity to attack. After some unsuccessful attempts, finally, on the night of the 6th to June 7, an opportunity arose: while Turkish officers had gathered on the flagship of the Turkish armada to celebrate the end of Ramadan, Psarian Konstantinos Kanaris managed to attach his fireship to the flagship, which became engulfed in flames. Some 2,000 men on board, including Kara Ali, the perpetrator of the Chios massacre, were killed.
