Vignoso’s first intention was to protect the Genoese settlements on the Black Sea against the attacks of the Tartars; but information received at Negroponte, where he touched on the way, led him to change his plans. There he found a fleet of Venetian and Rhodian galleys, under the Dauphin of Vienne, preparing to occupy Chios as a naval base for operations against the Turks in Asia Minor. Vignoso and his associates were offered large sums for their co-operation, but their patriotism rejected the idea of handing over to the rival republic an island which had belonged to the Genoese family of Zaccaria from 1304 to 1329, and which as recently as seventeen years earlier had been recovered by the Greeks. They made all sail for Chios, and offered to assist the islanders against a Venetian attack, if they would hoist the Genoese flag and admit a small Genoese garrison. The scornful refusal of the garrison was followed by the landing of the Genoese; four days sufficed to take the rest of the island; but the citadel made such a spirited resistance that three months passed before food gave out and on September 12 the capitulation was signed. The governor, Kalojanni Cybo, himself of Genoese extraction, and a member of the well-known Ligurian family which afterwards produced Pope Innocent VIII, made excellent terms for himself and his relatives, while the Greeks were to enjoy their former religious liberties and endowments, their property, and their privileges. A Genoese governor was to be appointed to administer the island according to the laws of the Republic, and 200 houses in the citadel were assigned at once for the use of the Genoese garrison. Vignoso proved by his example that he meant to keep these promises. He ordered his own son to be flogged publicly for stealing grapes from a vineyard belonging to one of the natives, and bequeathed a sum of money for providing poor Chiote girls with dowries as compensation for any damage that he might have inflicted upon the islanders.
