On 6 July, the Russians bombarded the Ottoman ships and land positions. At about 12:30 a.m. on the morning of  7 July, Orlov sent Samuel Greig (who transferred to "Rostislav") to attack with "Evropa", "Rostislav" and "Ne tron menya" forming a south–north line facing the Ottomans, and with "Saratov" in reserve, "Nadezhda" attacking the batteries at the eastern side of the bay entrance, "Afrika" attacking the batteries on the western side, and "Grom" near "Afrika". At about 1:30 a.m. or earlier (times were about 90 minutes earlier, according to Elphinstone), fire from "Grom" and/or "Ne tron menya" caused an Ottoman ship of the line to blow up after her main topsail caught fire, and the fire quickly spread to other ships of the line. By 2:00 a.m., two Ottoman ships of the line had blown up and more were on fire, and Greig sent in three fireships (the fourth, seeing the danger, stayed out), which contributed in a small way to the burning of almost the entire Ottoman fleet. At about 4:00 a.m., boats were sent in to save two ships of the line which were not burning, but one of these caught fire while it was being towed. The other, "Semend-i Bahri" 60, survived and was captured along with five galleys. Fighting ended at about 8:00 a.m. Russian casualties on 5 July were 14 killed, plus 636 killed in "Sviatoi Evstafii", and about 30 wounded, and on 7 July 11 killed. Ottoman casualties were much higher. Hüsameddin, Hasan Pasha and Cafer Bey survived. Hüsameddin was removed from his position, which was given to Cafer Bey. This was the only significant fleet battle during the Russo-Turkish War.
