Ottoman Capture of Negroponte

Timeline

1. 1470Euripus Strait · EuboeaUsing an attack on Rhodes as a cover, Mehmed II ordered Mahmud Pasha to sail the fleet from Gallipoli. On June 14, 1470, Ottoman ships entered the Negroponte channel, cutting the island off from the mainland and Venetian reinforcements, and immediately laid a combined land and sea siege on the castle.
2. 1470Castle of Negroponte · EuboeaOttoman forces bombarded the walls with heavy artillery while the defenders held out for nearly a month under the Venetian provveditore. Niccolò Canal's relief fleet cruised nearby waters but could not break into the strait. On July 12 the castle was stormed, with heavy casualties among defenders and residents, and Negroponte fell to the Ottomans.
3. 1470Island of Euboea · EuboeaAfter the castle fell, Venetian positions across the island surrendered one after another, and the Ottomans established rule over Euboea. News reaching Venice triggered political recriminations, and Canal was dismissed and exiled. The Republic lost its most important forward base in eastern Greece, and the war's focus shifted to the Albanian coast and peace negotiations.
