The Battle of the Oinousses Islands (Italian: Battaglia di Spalmadori) comprised two separate actions, on 9 and 19 February 1695 near the Oinousses (Turkish: Koyun Adaları), a small island group off Cape Karaburun in western Anatolia, between a Venetian fleet under Antonio Zeno and the Ottoman fleet under Mezzo Morto Hüseyin. The result of the first battle was a Venetian defeat, and although the second engagement ended in a draw, the Venetian position in Chios became untenable, forcing Zeno to abandon the island.
In the first engagement, Venetian casualties were 142 killed and 300 wounded on the sailing ships, excluding the three ships lost, and 323 killed and 303 wounded on the galleys. All together, less than 2500 casualties. In the second engagement, the Venetians were at a numerical disadvantage, due to the loss of three ships and the absence of the damaged San Vittorio. Venetian deaths were 132, and Fama Volante was damaged, along with 2 Ottoman sailing ships.
