At Chios, on the moonless night of 6–7 June 1822, forces under his command destroyed the flagship of the Ottoman admiral Nasuhzade Ali Pasha in revenge for the Chios massacre. The admiral was holding a "Bayram" celebration, allowing Kanaris and his men to position their fire ship without being noticed. When the flagship's powder store caught fire, all men aboard were instantly killed. The Turkish casualties comprised men, both naval officers and common sailors, as well as Nasuhzade Ali Pasha himself.
