The Turks took the islands of Tinos and Aegina, crossed the isthmus and took Corinth. Daniele Dolfin, commander of the Venetian fleet, thought it better to save the fleet than risk it for the Morea. When he eventually arrived on the scene, Nauplia, Modon, Corone and Malvasia had fallen. Lefkas in the Ionian islands, and the bases of Spinalonga and Suda on Crete which still remained in Venetian hands, were abandoned. The Turks finally landed on Corfù, but its defenders managed to throw them back. In the meantime, the Turks had suffered a grave defeat by the Austrians at Petrovaradin on 3 August 1716. New Venetian naval efforts in the Aegean and the Dardanelles in 1717 and 1718, however, met with little success. With the Treaty of Passarowitz (21 July 1718), Austria made large territorial gains, but Venice lost the Morea, for which her small gains in Albania and Venetian Dalmatia ("Linea Mocenigo") were little compensation. This was the last war of the Republic with Turkey.
