Tommaso Morosini of Venice set out with 23 ships from Crete on 20 March 1646, heading to Istanbul. They stopped at Tenedos, but failed to establish a foothold there when their ship caught fire, killing many of the crew. In 1654, Hozam Ali of the Turkish fleet landed at the island, gathering Turkish forces for a naval battle against the Venetians. This, the Battle of the Dardanelles (1654), the first of four in a series, the Ottomans won. After the Battle of the Dardanelles in 1656, Barbaro Badoer of the Venetians seized the island on 8 July. The Ottoman defeat weakened its Sultan Mehmed IV, then aged 16, and strengthened the Grand Vizier, Köprülü Mehmed Pasha.
