After the Morea was added to Ottoman lands, Negroponte, which threatened communications by land and sea, grew in importance. According to the TDV article on Negroponte, during the Ottoman–Venetian war of 1463–1479 Mehmed II besieged the city with a large army under his own command (1470), supported by the fleet commanded by Mahmud Pasha. The city was taken after a long siege and fierce street fighting; some 5,000 people are said to have been killed during and after the fighting and 2,500 deported to Istanbul. Negroponte remained an important Ottoman naval base until 1831.
