The Battle of Chesma took place on 5–7 July 1770 during the near and in Çeşme, in the area between the western tip of Anatolia and the island of Chios, which was the site of a number of past naval battles between the Ottoman Empire and the Republic of Venice. It was a part of the Orlov revolt of 1770, a precursor to the later Greek War of Independence (1821–1829), and the first of a number of disastrous fleet battles for the Ottomans against Russia. Today it is commemorated as a Day of Military Honour in Russia.
